  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing the overall configuration of an effect lighting device according to an embodiment of the present invention, and FIG. 2 is a front sectional view of the effect lighting device shown in FIG.

  The lighting device for performance 100 according to the present embodiment is configured so as to be installed outdoors, and obtains a performance effect by lighting it at night and illuminating the surroundings. And the said illuminating device 100 is a light extinction state in the daytime.

  As shown in FIG. 1, the lighting device for effect 100 includes a light emitting unit 1 embedded in the ground so as to be positioned below the ground (walking surface) 101, and a light guide unit provided above the light emitting unit 1. 2 and a reflection part 3 provided at the upper end of the light guide part 2.

  The light emitting unit 1 is configured to be able to irradiate light upward. As shown in FIG. 2, an LED light emitting element 11 as a light source and a housing 12 that houses the LED light emitting element 11 are provided. Have.

  An opening 12a for allowing light from the LED light emitting element 11 to pass therethrough is provided on the upper surface of the housing 12, and the light guide portion 2 is disposed so as to cover the opening 12a. A transparent plate material such as a glass plate is fitted into the opening 12a to close the upper surface of the housing 12, and the upper surface of the plate material and the lower end surface of the light guide portion 2 are fixed with an adhesive. Also good. In this case, it is preferable to use a resinous adhesive such as an acrylic resin that hardly affects the translucency.

  Further, as the light source, for example, a fluorescent lamp or the like other than the LED light emitting element 11 can be used.

  Although not shown in the figure, a power supply component such as a connector, a power supply circuit that supplies power to the power supply component, and the like are housed in the housing 12, and power is supplied to the power supply circuit by wiring that penetrates the housing 12. Is to be supplied.

  The light guide unit 2 is for guiding the light from the light emitting unit 1 to the upper reflection unit 3. The light guide portion 2 is formed in a solid quadrangular prism shape extending in the vertical direction, and a lower portion thereof is buried in the ground. For this reason, it appears to the pedestrian that the light guide unit 2 stands up directly from the ground 101.

  Moreover, the light guide part 2 of this embodiment is comprised by translucent materials, for example, inorganic materials, such as glass, and organic materials, such as an acrylic resin and a polycarbonate resin. By configuring the light guide unit 2 with a light-transmitting material in this way, the background can be visually recognized through the light guide unit 2 when the lighting device 100 is turned off, and the presence of the light guide unit 2 is diluted. can do.

  The light guide unit 2 has a horizontal cut surface at the lower end connected to the light emitting unit 1, and the lower end of the reflection unit 3 connected to the reflection unit 3 (a pair of reflection surfaces described later). 31) and a substantially V-shaped cut surface in front view.

  In addition to the above-described rectangular column shape, the light guide unit 2 may be of any shape such as a polygonal column shape such as a triangular column shape, a cylindrical shape, a semi-cylindrical shape, and a spherical shape. In the case where the side surface is rounded as described above, the background through the light guide unit 2 is distorted. Therefore, from the viewpoint of landscape protection, it is more preferable that the prismatic shape is not round. However, when the distortion is intentionally produced in the background, the light guide unit having a rounded shape may be used.

  Further, the light guide unit 2 may be not only a solid structure but also a so-called rectangular tube shape or a cylindrical shape having a hollow structure.

  In addition, when the light guide unit 2 has a hollow structure, the outer peripheral surface of the light guide unit 2 is coated with a coating for light distribution control, an uneven surface treatment, and an optical control sheet applied thereto, etc. You may go. If comprised in this way, it will become possible to gradation of the light from the light emission part 1, or to randomize the intensity | strength of the brightness | luminance, and to provide the lighting environment more rich in performance.

  The reflection part 3 is formed in a substantially V shape when viewed from the front, and reflects the light guided by the light guide part 2 to the side. The reflecting portion 3 has a pair of reflecting surfaces 31 that are inclined to the opposite sides and outward with respect to the horizontal plane, and the reflecting surfaces 31 illuminate both sides of the lighting device 100 with priority. Can be done.

  As such a reflection portion 3, a general-purpose one in which aluminum is vapor-deposited on a resin substrate can be used.

  In addition, the reflecting portion 3 is bonded to the substantially V-shaped upper end surface of the light guide portion 2 with a resinous adhesive such as an acrylic resin that hardly affects the translucency.

  Next, each aspect at the time of lighting and extinguishing of the lighting device 100 having the above configuration will be described.

  At the time of lighting, light from the light emitting unit 1 reaches the reflecting unit 3 through the light guide unit 2 and is reflected by the pair of reflecting surfaces 31 of the reflecting unit 3 to both sides of the lighting device 100.

Specifically, as shown in FIG. 2, the light a emitted from the LED light emitting element 11 almost directly travels straight up in the light guide unit 2 and is illuminated by the pair of reflection surfaces 31 of the reflection unit 3. both outer sides of the device 100 into (in FIG. 2 left and right outer side) is reflected in multiple directions. In addition, the light b emitted obliquely upward from the LED light emitting element 11 travels in the light guide unit 2 while being substantially totally reflected by the peripheral surface of the light guide unit 2 (boundary surface with the atmosphere). It is reflected towards both outer side of the lighting apparatus 100 by a pair of reflective surfaces 31. Although not shown, a part of the light b travels from the peripheral surface (interface with the atmosphere) of the light guide 2 in the direction of the external atmosphere, so that the rectangular light guide 2 is formed. It starts to emit light dimly.

  On the other hand, when the light is turned off, the background can be easily visually recognized through the light guide portion 2 made of a translucent material, and the presence of the light guide portion 2 becomes dilute, so that the lighting device 100 is not sufficiently conspicuous.

  In addition, when the pedestrian approaches the lighting device 100 and looks at the light emitting unit 1 to visually recognize the light emitting unit 1, the light guide unit 2 is disposed between the pedestrian and the light emitting unit 1. It is difficult for a person to visually recognize the light emitting unit 1.

As a result, the background through the light guide 2 is less likely to be distorted, so that the lighting device 100 can be made less noticeable.

  Moreover, in this embodiment, since the LED light emitting element 11 was used as a light source as mentioned above, the illuminating device 100 can be reduced in size. Further, in this case, since it becomes possible to fill the housing 12 with a waterproof silicone resin or the like, there is no need to worry about dew condensation in the housing 12.

  In addition, although the case where the lighting apparatus 100 for production was installed outdoors was demonstrated in the said embodiment, not only this but the said lighting apparatus 100 can also be installed indoors. In this case, the light emitting unit is provided below the floor surface, which is a walking surface, and it appears to the pedestrian that the light guide unit stands up directly from the floor surface.

  In the above-described embodiment, the example in which the substantially V-shaped reflecting portion 3 is provided in the front view has been described. However, the present invention is not limited thereto, and as illustrated in FIG. Good. In this case, the light guided by the light guide unit 2 can be efficiently reflected in four directions by the four reflection surfaces 41 inclined outward from the reflection unit 4.
