Description

  Embodiments described herein relate generally to a lighting fixture.

  There is an energy management system that monitors power consumed in homes and buildings and controls appliances through a network. In the lighting fixture, it is required to deal with such an energy management system only with the lighting fixture without requiring other devices. In order to support an energy management system with only lighting equipment, for example, a communication unit that performs communication with an external device, a control unit that performs control in accordance with an instruction from the external device, and the like are required. When a communication unit, a control unit, or the like is mounted on the same surface of a plate-like support, the support has a large area. Increasing the area of the support makes it difficult to install the lighting fixture on the ceiling or the like. For this reason, in a lighting fixture, it is desired to be compatible with an energy management system while suppressing an increase in the area of the support.

  Each embodiment will be described below with reference to the drawings.

  The drawings are schematic or conceptual, and the relationship between the thickness and width of each part, the size ratio between the parts, and the like are not necessarily the same as actual ones. Further, even when the same part is represented, the dimensions and ratios may be represented differently depending on the drawings.

  Drawing 1 (a) and Drawing 1 (b) are mimetic diagrams showing the lighting fixture concerning an embodiment.

  FIG. 1A is a schematic plan view of the lighting fixture 10, and FIG. 1B is a schematic side view of the lighting fixture 10. In FIG. 1B, for the sake of convenience, a part of the lighting fixture 10 is cut out and illustrated.

  As illustrated in FIGS. 1A and 1B, the lighting fixture 10 includes a fixture body 12, a support body 14, a communication unit 16, a control unit 18, a first terminal block 21, A two-terminal block 22 and a third terminal block 23 are included. The instrument body 12 holds the light source unit 30. The instrument body 12 holds the light source unit 30 in a detachable manner, for example. The light source unit 30 includes a light source 80 (see FIG. 3A) that emits light. That is, the instrument body 12 holds the light source 80. The instrument main body 12 holds the light source 80 in a detachable manner, for example. The support 14 supports, for example, each of the communication unit 16, the control unit 18, the first terminal block 21, the second terminal block 22, and the third terminal block 23.

  The luminaire 10 is attached to the ceiling of the room with the light source unit 30 facing downward, for example. The lighting fixture 10 is used as a downlight, for example. The lighting fixture 10 can communicate with an external device via the communication unit 16. Thereby, in lighting fixture 10, it can apply to energy management systems, such as HEMS (Home Energy Management System) and BEMS (Building Energy Management System), for example with lighting fixture 10 alone. In the lighting fixture 10, for example, lighting and extinguishing can be controlled from the outside by a portable terminal that can be connected to a network. For example, dimming control can be performed from a portable terminal or the like.

  The instrument body 12 includes, for example, a cylindrical frame body 41 and a support plate 42 that supports the frame body 41. In this example, the frame body 41 is cylindrical. The frame body 41 may be, for example, a rectangular tube shape. The instrument main body 12 holds the light source unit 30 inside the frame body 41. For example, the instrument body 12 holds the light source unit 30 in a state where the optical axis OA of the light source unit 30 is parallel to the central axis CA of the frame body 41. In this example, the optical axis OA is substantially coaxial with the central axis CA. The optical axis OA may be inclined with respect to the central axis CA. Further, the optical axis OA may be variable with respect to the central axis CA. That is, the luminaire 10 may be, for example, a universal type downlight that can change the light irradiation direction.

  The support plate 42 is attached to one end of the frame body 41 in the axial direction, for example. In this example, the support plate 42 closes one end of the frame body 41 in the axial direction. The frame body 41 is supported by the support plate 42 by screwing or the like, for example.

  For the frame body 41 and the support plate 42, for example, a metal material such as iron, aluminum, or stainless steel is used. Thereby, the heat dissipation of the heat | fever emitted from the light source unit 30 at the time of lighting can be improved, for example.

  A flange portion 44 is provided on the other end in the axial direction of the frame body 41 (the end portion opposite to the support plate 42). For example, the flange portion 44 protrudes outward from the end portion of the frame body 41 in a direction perpendicular to the central axis CA.

  A pair of attachment springs 45 are provided on the outer surface of the frame body 41. Each attachment spring 45 is used for attaching the lighting fixture 10 to the ceiling or the like. Each attachment spring 45 has a leaf spring shape, for example. Each attachment spring 45 may be in the form of a torsion spring, for example.

  When installing the luminaire 10 on the ceiling, an embedding hole is provided in the ceiling board in advance. At this time, the diameter of the embedding hole is larger than the outer diameter of the frame body 41 and smaller than the outer diameter of the flange portion 44. The lighting fixture 10 inserts the support body 14 and the frame body 41 into the embedding hole from the indoor side with the flange portion 44 facing the indoor side. Then, the ceiling plate is sandwiched between the flange portion 44 and each mounting spring 45. Thereby, the lighting fixture 10 is attached to a ceiling board. One surface of the flange portion 44 is exposed to the ceiling. The flange portion 44 also functions as a decorative frame that covers an embedding hole or the like, for example.

  The support body 14 includes a first plate portion 51 and a second plate portion 52. The first plate portion 51 is attached to the instrument body 12. In this example, the first plate portion 51 is attached to the support plate 42. For example, the first plate portion 51 may be attached to the frame body 41.

  In this example, the 1st board part 51 is attached to the instrument main body 12 so that rotation is possible centering around the rotating shaft RA. The rotation axis RA is set, for example, in a direction that intersects the optical axis OA. In this example, the rotation axis RA is orthogonal to the optical axis OA. In other words, the rotation axis RA is orthogonal to the central axis CA. Thereby, for example, when the lighting apparatus 10 is installed on a ceiling or the like, the support body 14 can be bent with respect to the apparatus main body 12, and the support body 14 can be easily inserted into the embedding hole. The lighting fixture 10 can be easily installed on the ceiling or the like. The direction of the rotation axis RA may be arbitrary. Moreover, the 1st board part 51 may be fixed to the instrument main body 12 by screwing etc., for example. The first plate portion 51 may be formed integrally with the support plate 42, for example.

  The first plate portion 51 extends from the instrument body 12 in the first direction D1. The first direction D1 is, for example, a direction perpendicular to the rotation axis RA. The first plate portion 51 has a first surface 51a. The first surface 51a has, for example, a rectangular shape extending in the first direction D1. For example, the first surface 51a intersects the optical axis OA. For example, the first surface 51a is orthogonal to the optical axis OA. In this example, the first plate portion 51 is rotatable with respect to the instrument body 12. That is, the first plate portion 51 can set, for example, a state in which the first surface 51a is orthogonal to the optical axis OA.

  The second plate portion 52 faces the first surface 51a and has a second surface 52a. In this example, the second surface 52a is substantially parallel to the first surface 51a. The second surface 52a does not necessarily have to be parallel to the first surface 51a. The second surface 52a is a surface facing the first surface 51a of the second plate portion 52, for example. The second surface 52a may be, for example, a surface facing the side opposite to the first surface 51a of the second plate portion 52. The 2nd board part 52 has the outer peripheral part 52b surrounding the circumference | surroundings of the 2nd surface 52a, for example. The 2nd board part 52 is box shape, for example. The second plate portion 52 is attached to the first plate portion 51 by, for example, screwing.

  For the first plate portion 51 and the second plate portion 52, for example, a metal material such as iron, aluminum, or stainless steel is used. For example, a resin material or the like may be used for the first plate portion 51 and the second plate portion 52. The material of the 1st board part 51 and the 2nd board part 52 may be arbitrary materials which can obtain required rigidity. The first plate portion 51 and the second plate portion 52 are formed, for example, by bending a metal plate. In this example, the second plate portion 52 is provided on the light irradiation direction side with respect to the first plate portion 51. The second plate portion 52 may be provided on the opposite side. That is, the first plate portion 51 may be provided on the light irradiation direction side with respect to the second plate portion 52.

  Drawing 2 is a mimetic diagram showing a part of lighting fixture concerning an embodiment.

  FIG. 2 illustrates a state in which the instrument main body 12 is viewed from the flange portion 44 side. FIG. 2 shows a state where the light source unit 30 is removed.

  As shown in FIG. 2, a socket 46 is provided inside the frame body 41. The socket 46 is provided at the end opposite to the flange portion 44 inside the frame body 41. The socket 46 is attached to the support plate 42 by, for example, screwing. For example, the socket 46 detachably holds the light source unit 30 and obtains an electrical connection with the held light source unit 30. However, the socket 46 is electrically insulated from the frame body 41 and the support plate 42. The socket 46 corresponds to, for example, a GX53 type base. The shape of the socket 46 is not limited to this, and may be any shape.

  A cutout 41 a is provided at the end of the frame body 41 on the support plate 42 side. The notch 41a is provided, for example, at a position facing the support body 14 side of the frame body 41. A notch 52c is provided on the surface of the outer peripheral portion 52b of the second plate portion 52 facing the instrument body 12 side. A pair of wirings 60a and 60b is inserted into the notch 41a and the notch 52c. One end of each of the wirings 60 a and 60 b is connected to the socket 46. The other ends of the wirings 60 a and 60 b are connected to the control unit 18. Thereby, the control unit 18 and the socket 46 are electrically connected via each wiring 60a, 60b.

  Further, a notch 42 a is provided at a position facing the notch 52 c of the support plate 42. For example, when the lighting fixture 10 is installed on a ceiling or the like while the support 14 is bent or stretched with respect to the fixture body 12, the notches 42a are connected to the support plate 42 and the first plate portion. It is suppressed that it is pinched between 51. For example, it is possible to prevent the wirings 60a and 60b from being damaged.

  Fig.3 (a)-FIG.3 (c) are schematic diagrams showing the light source unit which concerns on embodiment.

  FIG. 3A is a schematic side view of the light source unit 30. FIG. 3B is a schematic plan view of the light source unit 30. FIG. 3C is a schematic perspective view of the light source unit 30.

  3A to 3C, the light source unit 30 includes, for example, a light source 80, a power supply circuit 81 that supplies power to the light source 80, and a cylinder that houses the light source 80 and the power supply circuit 81. A case 82, a light-transmitting cover 83 that closes one end of the case 82, and a cap 84 provided at the other end of the case 82.

  For the light source 80, for example, a COB (Chip On Board) type light emitting module is used. The COB type light emitting module includes, for example, a substrate, a plurality of LED (Light Emitting Diode) chips provided side by side on the substrate, and a phosphor layer provided on each LED chip. For example, ceramics or the like is used for the substrate. For example, an LED that emits blue light is used as the LED chip. For example, a yellow phosphor is used for the phosphor layer. Thereby, for example, substantially white light can be irradiated. The light source 80 may be, for example, an SMD (Surface Mount Device) type light emitting module. The light source 80 may be, for example, an organic light emitting diode (OLED), an inorganic electroluminescence light emitting element, an organic electroluminescence light emitting element, or other electroluminescent light emission. An element or the like may be used.

  For example, the power supply circuit 81 converts AC power supplied via the socket 46 and the like into DC power, and supplies the converted DC power to the light source 80. As a result, the light source 80 is turned on and light is emitted from the light source 80.

  The housing 82 holds the light source 80 and the power supply circuit 81 in an internal space, for example. For the housing 82, for example, a metal material such as iron, aluminum, or stainless steel is used. Thereby, the heat dissipation of the heat | fever generated with the lighting of the light source 80 can be improved. A plurality of heat radiating fins 85 are provided on the outer surface of the housing 82. For example, the heat radiation fins 85 extend along the optical axis direction of the light source 80 and are arranged around the optical axis. Thereby, heat dissipation can be improved more.

  For the cover 83, for example, a resin material such as polycarbonate having light diffusibility is used. Thereby, for example, luminance unevenness and color unevenness of irradiation light can be suppressed. The cover 83 does not necessarily have light diffusibility. The cover 83 may be transparent, for example. The cover 83 only needs to have at least light transmittance.

  The base part 84 is provided with a pair of electrode pins 86. For example, each electrode pin 86 is electrically connected to the electrode portion of the socket 46 while being held by the socket 46. Each electrode pin 86 is electrically connected to the power supply circuit 81. As a result, power is supplied to the power supply circuit 81 via the socket 46 and each electrode pin 86. For example, AC power is supplied to the power supply circuit 81.

  The base portion 84 has, for example, a GX53 type base structure. The base portion 84 fits into the socket 46 of the lighting fixture 10. As a result, the light source unit 30 is held by the instrument body 12 via the base portion 84. The shape of the base portion 84 is not limited to this, and may be any shape corresponding to the shape of the socket 46.

  Drawing 4 is a typical side view showing a part of lighting fixture concerning an embodiment.

  FIG. 4 shows a state in which the support body 14 is viewed in parallel to the first direction D1.

  FIG. 5 is a schematic block diagram illustrating the lighting apparatus according to the embodiment.

  FIG. 5 schematically shows an electrical connection state of the lighting fixture 10.

  4 and 5, the first terminal block 21 has a pair of input terminals 21a and 21b to which a pair of power supply lines 70a and 70b for supplying power are connected. The first terminal block 21 is used for power input. The number of input terminals provided on the first terminal block 21 is not limited to two, and may be one or three or more.

  Each power supply line 70a, 70b is connected to a commercial power supply 90, for example. Thereby, for example, an AC power supply is input to the first terminal block 21. Each power line 70a, 70b may be connected to, for example, a generator. For example, the power supply lines 70 a and 70 b may be connected to a dimmer, and an AC power supply that is phase-controlled may be input to the first terminal block 21. The power source input to the first terminal block 21 may be a DC power source.

  The second terminal block 22 has a pair of input terminals 22a and 22b to which a pair of signal lines 71a and 71b for inputting the first control signal are connected. The second terminal block 22 is used for inputting the first control signal. The number of input terminals provided on the second terminal block 22 is not limited to two, and may be one or three or more.

  Each signal line 71a, 71b is connected to a wall switch 91, for example. The wall switch 91 is provided, for example, on the inner wall of the room. The wall switch 91 includes, for example, a changeover switch 91a for switching between lighting and extinguishing, and a variable resistor 91b for performing dimming. The first control signal includes, for example, switching information for switching between lighting and extinguishing and phase control information for phase controlling the AC power supply. For example, the lighting fixture 10 switches between turning on and off the light source unit 30 according to the input of the first control signal, and dimming the light source unit 30 according to the input of the first control signal.

  For example, a change in resistance value due to the operation of the changeover switch 91a and the variable resistor 91b may be input to the second terminal block 22 as the first control signal. Alternatively, an electrical signal corresponding to the operation of the changeover switch 91a and the variable resistor 91b may be generated by the wall switch 91, and the electrical signal may be input to the second terminal block 22 as a first control signal. The device connected to each signal line 71a, 71b is not limited to the wall switch 91. The device connected to each signal line 71a, 71b may be any device that can input the first control signal including the switching information, the phase control information, and the like to the lighting fixture 10 without using a network or the like, for example.

  The communication unit 16 has an input terminal 16a to which a communication line 72 for connecting to the network 92 is connected. The communication unit 16 receives the second control signal from the external device 93 via the network 92.

  The network 92 may be a network in a specific area such as a LAN (Local Area Network) or a WAN (Wide Area Network), or may be a public network such as the Internet. For example, a LAN adapter or the like is used for the communication unit 16. The communication unit 16 may be, for example, any device that supports the communication standard of the network 92. The communication line 72 is connected to the network 92 via, for example, a modem or a router (not shown). For the communication line 72, for example, a LAN cable or the like is used. As the external device 93, for example, any electronic device that can be connected to the network 92, such as a personal computer or a mobile phone, can be used. The external device 93 accesses the control unit 18 via, for example, a dedicated server. The external device 93 may directly access the control unit 18.

  The second control signal includes, for example, switching information for switching between lighting and extinguishing and phase control information for phase controlling the AC power supply. For example, the lighting fixture 10 switches between turning on and off the light source unit 30 according to the input of the second control signal, and dimming the light source unit 30 according to the input of the second control signal.

  As described above, the control unit 18 is electrically connected to the socket 46 via the wires 60a and 60b. The control unit 18 is electrically connected to the light source unit 30 (light source 80) held by the instrument body 12 via the wirings 60a and 60b and the socket 46.

  The control unit 18 is electrically connected to the first terminal block 21 through a pair of wires 61a and 61b. The control unit 18 is electrically connected to the power supply lines 70a and 70b via the wires 61a and 61b and the first terminal block 21. As a result, power from each of the power lines 70 a and 70 b is supplied to the control unit 18. For example, AC power is supplied to the control unit 18. The control unit 18 is driven by supplying AC power, for example.

  The control unit 18 is electrically connected to the second terminal block 22 via a pair of wires 62a and 62b. The control unit 18 is electrically connected to the signal lines 71 a and 71 b via the wirings 62 a and 62 b and the second terminal block 22. As a result, the first control signal is input to the control unit 18.

  The control unit 18 is electrically connected to the communication unit 16 via the wiring 63. As a result, the second control signal is input to the control unit 18.

  The control unit 18 controls the supply of power to the light source unit 30 (light source 80) based on at least one of the first control signal and the second control signal. For example, the control unit 18 switches between supplying power to the light source unit 30 and stopping the supply based on switching information included in the first control signal and the second control signal. The light source unit 30 converts the AC power supplied from the control unit 18 into a DC power by the power circuit 81 and supplies the converted DC power to the light source 80. Thereby, the light source 80 of the light source unit 30 is turned on. As described above, in the lighting apparatus 10, the light source unit 30 is turned on and off according to the operation of the changeover switch 91 a of the wall switch 91 or the operation of the external device 93.

  The control unit 18 also performs phase control on the AC power supply based on the phase control information included in the first control signal and the second control signal, and outputs the phase-controlled AC power supply to the light source unit 30. Thereby, the light source unit 30 is dimmed according to the operation of the changeover switch 91 a of the wall switch 91 or the operation of the external device 93.

  In addition, for phase control, for example, a phase control (leading edge) method for controlling a conducting phase in a period in which the absolute value of the AC voltage reaches a maximum value from the zero cross of the AC voltage, and the absolute value of the AC voltage is the maximum value. And an anti-phase control (trailing edge) method for controlling a phase to be cut off during a period in which the AC voltage is zero-crossed.

  As described above, in the lighting fixture 10, the lighting and extinction of the light source unit 30 and the dimming can be controlled even from the external device 93. Therefore, the luminaire 10 can correspond to an energy management system such as HEMS. The lighting fixture 10 can be adapted to the energy management system with only the lighting fixture 10 without requiring other devices or the like.

  Note that, when AC power that is phase-controlled by a dimmer or the like is supplied from each of the power lines 70a and 70b, the control unit 18 may output the light source unit 30 as it is without performing phase control. Alternatively, the phase of the AC power supply after the phase control may be further controlled by the control unit 18.

  The dimming control by the control unit 18 is not limited to phase control, and may be PWM control, for example. In this case, control information for PWM control may be included in the first control signal and the second control signal. When the light source unit 30 includes multi-color types of light emitting elements, for example, the control unit 18 can perform toning control by enabling the light emitting elements to be lit to be selected for each color. Good. In this case, control information for toning control may be included in the first control signal and the second control signal.

  The third terminal block 23 is electrically connected to the control unit 18 through a pair of wires 64a and 64b. The third terminal block 23 has a pair of output terminals 23a and 23b that branch and output the power output from the control unit 18 to the light source unit 30 (light source 80). The control unit 18 outputs an AC power source to the light source unit 30 and the third terminal block 23 in accordance with the operation of the wall switch 91 and the external device 93. For example, the control unit 18 outputs a phase-controlled AC power supply to the light source unit 30 and the third terminal block 23.

  For example, a pair of power supply lines 73a and 73b is connected to each output terminal 23a and 23b. And another lighting fixture 100 is connected to each power supply line 73a, 73b.

  The lighting fixture 100 includes, for example, an input terminal block 101, a socket 102, and an output terminal block 103. The input terminal block 101 has, for example, a pair of input terminals to which the power supply lines 73a and 73b are connected. The socket 102 is electrically connected to the input terminal block 101. The socket 102 is substantially the same as the socket 46 of the lighting fixture 10, holds the light source unit 30 in a detachable manner, and is electrically connected to the light source unit 30. The socket 102 corresponds to, for example, a GX53 type base.

  The lighting fixture 100 turns on the light source unit 30 held in the socket 102 by the AC power output from the third terminal block 23 of the lighting fixture 10. The output terminal block 103 is electrically connected to the input terminal block 101. The output terminal block 103 has a pair of output terminals for branching and outputting the power input to the input terminal block 101.

  For example, a pair of power supply lines 74a and 74b is connected to the output terminal block 103, and another lighting device 100 is connected via the power supply lines 74a and 74b.

  In this way, a plurality of lighting fixtures 100 can be connected to the lighting fixture 10. And in the lighting fixture 10, the some light source unit 30 connected to each of the lighting fixture 10 and the lighting fixture 100 can be made to light by the substantially same control aspect. For example, by installing the lighting fixture 10 and the lighting fixture 100 side by side, the plurality of light source units 30 can be turned on with the same brightness. The lighting apparatus 100 includes a communication unit 16 and a control unit.

18 need not be provided. Thereby, when the several light source unit 30 is lighted, the number of parts of the whole system can be reduced. For example, the cost of the system can be reduced. That is, the lighting fixture 10 is, for example, a Master fixture, and the lighting fixture 100 is, for example, a Slave fixture. The plurality of lighting fixtures 100 are connected to the lighting fixture 10 in parallel, for example.

  Drawing 6 (a) and Drawing 6 (b) are mimetic diagrams showing another lighting fixture concerning an embodiment.

  FIG. 6A is a schematic plan view showing the lighting fixture 100, and FIG. 6B is a schematic side view showing the lighting fixture 100. FIG.

  As illustrated in FIGS. 6A and 6B, the lighting fixture 100 further includes, for example, a frame body 104, a support plate 105, and a pair of attachment springs 106. A flange portion 107 is provided at one end of the frame body 104. Since the frame body 104 and each attachment spring 106 are substantially the same as the frame body 41 and each attachment spring 45 of the lighting fixture 10, detailed description is abbreviate | omitted. A socket 102 is provided inside the frame body 104, and the light source unit 30 is held inside the frame body 104. Similar to the lighting fixture 10, the lighting fixture 100 is attached to the ceiling plate by sandwiching the ceiling plate between the flange portion 107 and each mounting spring 106.

  The support plate 105 is attached to one end of the frame body 104 in the axial direction, for example. The input terminal block 101 and the output terminal block 103 are attached to a support plate 105. For example, after the lighting fixture 100 is attached to the ceiling board, the input terminal block 101 is electrically connected to the third terminal block 23 of the lighting fixture 10 via the power supply lines 73a and 73b. Alternatively, the input terminal block 101 is electrically connected to the output terminal block 103 of another lighting apparatus 100 via the power supply lines 74 a and 74 b. Thereby, according to the electric power supply from the lighting fixture 10, the light source unit 30 hold | maintained at the lighting fixture 100 lights.

  As illustrated in FIG. 1B and FIG. 4, in the lighting fixture 10, the control unit 18 is provided on the second surface 52 a, for example. The control unit 18 may be provided on the first surface 51a. The communication unit 16 is provided on the same surface as the control unit 18. In this example, the communication unit 16 is provided on the second surface 52a. The communication unit 16 is arranged at a position farther from the instrument body 12 than the control unit 18. The communication unit 16 is provided with the input terminal 16a facing away from the instrument body 12 in the first direction D1.

  The first terminal block 21 is provided on the support body 14 with the input terminals 21 a and 21 b facing away from the instrument body 12 in the first direction D <b> 1, farther away from the instrument body 12 than the communication unit 16. The second terminal block 22 is provided on the support 14 with the input terminals 22a and 22b facing away from the instrument main body 12 in the first direction D1 and farther from the instrument main body 12 than the communication unit 16. The third terminal block 23 is provided on the support body 14 with the output terminals 23 a and 23 b facing away from the instrument body 12 in the first direction D <b> 1, farther from the instrument body 12 than the communication unit 16. The first terminal block 21, the second terminal block 22, and the third terminal block 23 are provided on a different surface from the communication unit 16 and the control unit 18. In this example, the first terminal block 21, the second terminal block 22, and the third terminal block 23 are provided on the first surface 51a. Each of the 1st terminal block 21, the 2nd terminal block 22, and the 3rd terminal block 23 is arranged in the direction perpendicular to the 1st direction D1, for example.

  In the lighting fixture 10, the input terminal 16a of the communication unit 16 does not overlap with each of the first terminal block 21, the second terminal block 22, and the third terminal block 23 in the first direction D1. In the lighting fixture 10, the distance between the first surface 51a and the second surface 52a, the size and position of each part, and the like are adjusted in this way.

  Moreover, in the lighting fixture 10, the communication unit 16 and the control unit 18 are provided in the 2nd surface 52a, and the 1st terminal block 21, the 2nd terminal block 22, and the 3rd terminal block 23 are provided in the 1st surface 51a.

Thereby, in the lighting fixture 10, each wiring 61a, 61b, 62a, 62b, 64a, and 64b can be passed through the space between the 1st board part 51 and the communication unit 16. FIG. For example, the wirings 61a, 61b, 62a, 62b, 64a and 64b can be easily routed. For example, electrical connection between each of the first terminal block 21, the second terminal block 22, and the third terminal block 23 and the control unit 18 can be facilitated.

  In lighting fixtures that support energy management systems, the number of components such as communication units and control units, the number of input / output wirings, and the like increase compared to non-compliant fixtures. For this reason, in the luminaire corresponding to the energy management system, for example, when the respective components are arranged on the same plane, the support has a large area. For example, the wiring insertion surface (surface orthogonal to the first direction D1) for inserting the wiring has a rectangular shape. For example, the length of the wiring insertion surface becomes longer than the diameter of the embedding hole for inserting the instrument, and there is a possibility that the support cannot be inserted into the embedding hole.

  On the other hand, in the lighting fixture 10 which concerns on this embodiment, it distributes to two surfaces and each component is arrange | positioned. Thereby, for example, the shape of the wiring insertion surface can be made closer to a square. For example, the length of the diagonal line on the wiring insertion surface can be shortened. That is, an increase in the area of the first surface 51a and the second surface 52a of the support 14 can be suppressed. Thus, in the lighting fixture 10 which concerns on this embodiment, it can respond to an energy management system, suppressing the enlargement of the 1st surface 51a of the support body 14 and the 2nd surface 52a.

  Moreover, in the lighting fixture 10 which concerns on this embodiment, it is spaced apart from the fixture main body 12 in order of the control unit 18, the communication unit 16, and the 1st terminal block 21-the 3rd terminal block 23 in the 1st direction D1. And the input terminal 16a of the communication unit 16 is turned to the opposite side to the instrument main body 12. The input terminals 21 a and 21 b of the first terminal block 21 are directed to the opposite side of the instrument body 12. The input terminals 22 a and 22 b of the second terminal block 22 are directed to the opposite side of the instrument body 12. The output terminals 23 a and 23 b of the third terminal block 23 are directed to the opposite side of the instrument body 12. As a result, each of the input terminals 16a, 21a, 21b, 22a, 22b and the output terminals 23a, 23b, respectively.

Wiring can be easily connected to this.

  Further, as described above, the first surface 51a and the second surface are shifted by shifting the positions of the control unit 18, the communication unit 16, and the first terminal block 21 to the third terminal block 23 in the first direction D1. The distance between 52a can be made closer. For example, the length of the diagonal line on the wiring insertion surface can be further shortened. For example, an increase in area of the first surface 51a and the second surface 52a of the support 14 can be further suppressed.

  Furthermore, in the lighting fixture 10 which concerns on this embodiment, the input terminal 16a of the communication unit 16 does not overlap with each of the 1st terminal block 21, the 2nd terminal block 22, and the 3rd terminal block 23 in the 1st direction D1. Thereby, for example, the connection of the communication line 72 to the input terminal 16a of the communication unit 16 can be made easier.

  The lighting fixture 10 has a third terminal block 23 for output, and a plurality of different lighting fixtures 100 can be connected thereto. Thereby, in the lighting fixture 10, failure diagnosis of the control unit 18 and the light source unit 30 can be performed. For example, when each light source unit 30 of the lighting fixture 10 and the lighting fixture 100 does not light, it can diagnose that the control unit 18 is out of order. On the other hand, when any one of the light source units 30 of the lighting fixture 10 and the lighting fixture 100 is not turned on, it can be diagnosed that the power supply circuit 81 of the light source unit 30 is malfunctioning. Further, for example, even when the lighting fixture 10 is used alone, the failure diagnosis as described above can be performed by connecting the lighting fixture 100 to the third terminal block 23.

  FIG. 7 is a schematic side view showing another lighting apparatus according to the embodiment.

  As shown in FIG. 7, in the lighting fixture 110, the 3rd terminal block 23 is attached to the 2nd surface 52a. For example, depending on the size of the communication unit 16 and the sizes of the first terminal block 21 to the third terminal block 23, the third terminal block 23 is provided on the second surface 52a in this way, so The increase in area of the first surface 51a and the second surface 52a can be further suppressed. That is, by attaching the third terminal block 23 to the same surface as the communication unit 16 and the control unit 18, it is possible to further suppress an increase in the area of the first surface 51 a and the second surface 52 a of the support 14.

  The first terminal block 21 or the second terminal block 22 may be attached to the same surface as the communication unit 16 and the control unit 18. Further, any two of the first terminal block 21 to the third terminal block 23 may be attached to the same surface as the communication unit 16 and the control unit 18. That is, at least one of the first terminal block 21 to the third terminal block 23 may be provided on a different surface from the communication unit 16 and the control unit 18.

  FIG. 8 is a schematic block diagram showing another lighting apparatus according to the embodiment.

  As illustrated in FIG. 8, the lighting fixture 120 further includes a fourth terminal block 24. The fourth terminal block 24 is electrically connected to the control unit 18 via a pair of wires 65a and 65b. The fourth terminal block 24 has an output terminal that branches and outputs the power output from the control unit 18 to the light source unit 30. In this example, the control unit 18 outputs AC power to the light source unit 30, the third terminal block 23, and the fourth terminal block 24 in accordance with the operation of the wall switch 91 and the external device 93. For example, the control unit 18 outputs a phase-controlled AC power supply to the light source unit 30, the third terminal block 23, and the fourth terminal block 24.

  The fourth terminal block 24 may be attached to the first surface 51a or may be attached to the second surface 52a. Thus, the lighting fixture may include more than two terminal blocks. It is only necessary that at least one of the plurality of terminal blocks is provided on a surface different from the communication unit 16 and the control unit 18.

  For example, an inspection cable 75 is connected to the output terminal of the fourth terminal block 24. Inspection cave

An inspection device 94 is connected to the cable 75. The inspection device 94 diagnoses the failure of the control unit 18 and the failure of the light source unit 30 by analyzing the output from the control unit 18, for example. Thus, by providing the 4th terminal block 24 and enabling it to connect the test | inspection apparatus 94, the failure of the control unit 18 and the failure of the light source unit 30 can be diagnosed more appropriately, for example. As the inspection device 94, for example, a portable electronic device such as a notebook personal computer or a tablet personal computer is used. As the inspection cable 75, for example, a USB cable or an IEEE 1394 cable is used. The output terminal of the fourth terminal block 24 corresponds to the standard of the inspection cable 75. A plurality of output terminals and inspection cables 75 of the fourth terminal block 24 may be provided.

  In each of the above embodiments, the light source unit 30 is held by the instrument main body 12, but the present invention is not limited thereto, and for example, the light source 80 itself such as an LED may be held by the instrument main body 12. The instrument body 12 may hold the light source 80 in a detachable manner, for example, via a connector. For example, the light source 80 may be mounted on a substrate provided in the instrument body 12. That is, the light source 80 may not necessarily be detachable from the instrument body 12.
