[Electrode connection status]
Next, the connection state of the electrode 14 of the illumination device 1 according to the embodiment will be described with reference to FIGS. 5A and 5B. FIG. 5A is a diagram illustrating a state in which the first power supply path 18a and the second power supply path 18b are connected in parallel in the lighting device 1 according to the embodiment. FIG. 5B is a diagram illustrating a state in which the first power supply path 18a and the second power supply path 18b are connected in series in the lighting device 1 according to the embodiment. 5A and 5B, the power supply line 22 that electrically connects the power supply units 21 among the power supply lines 22 is indicated by a solid line, and the power supply line 22 that is electrically disconnected between the power supply units 21 is illustrated.

  Thus, the first power supply path 18a and the second power supply path 18b are connected in parallel by the first power supply line 22a and the second power supply line 22b. In this case, the first electrode 14a and the second electrode 14b are electrically connected, and power is supplied from the power supply device 30 to the first power supply path 18a. Further, the third electrode 14c and the fourth electrode 14d are electrically connected, and power is supplied from the power supply device 30 to the second power supply path 18b.

In this case, the first electrode 14a and the fourth electrode 14d are electrically connected, and power is supplied from the power supply device 30 to the first power supply path 18a and the second power supply path 18b. For example, power is supplied to the first power supply path 18a and the second power supply path 18b connected in series from the power supply device 30 having a voltage V2 (= V1 × 2) that is twice that of V1. That is, the power supply unit 21 electrically connects the first electrode 14a and the fourth electrode 14d of the plurality of power supply paths 18a and 18b and supplies power with a common voltage. In this way, the light emitting module 2 irradiates the illumination space with light.

  That is, the illumination device 1 according to the embodiment can supply power to the same light emitting module 2 from the power supply device 30 having a different voltage, and can irradiate the illumination space with light.

[Effect of the embodiment]
As described above, the socket 10 according to the embodiment is provided with the substrate 10 having the plurality of electrodes 14 for supplying power, and electrically connects the plurality of electrodes 14. Specifically, the socket 7 electrically connects the first electrode 14a and the second electrode 14b of the first power supply path 18a in the first power supply path 18a and the second power supply path 18b connected in parallel, and The third electrode 14c and the fourth electrode 14d of the two power supply paths 18b can be electrically connected to supply power.

Can be supplied. Therefore, the same light emitting module 2 can be used even when the usage is different, for example, when the driving voltage is different. Thereby, it is not necessary to design and develop the light emitting module 2 for each application, and it is not necessary to manufacture a different member for each application, and the light emitting module 2, particularly the substrate 10 can be shared.

  Further, the socket 7 according to the embodiment changes the connection state of the electrode 14. Specifically, the socket 7 according to the embodiment includes a plurality of power supply lines 22 that connect between the power supply units 21 that are electrically connected to the electrodes 14. And the connection state of the electrode 14 is changed by interrupting a part of the feeder 22. Therefore, the connection state of the electrode 14 can be easily changed according to the application.

(Modification)
In the lighting device 1 according to the above-described embodiment, the connection state of the electrode 14 is changed by providing the power supply line 22 in the socket 7 and cutting a part of the power supply line 22, but is not limited thereto. For example, a connection state of the electrode 14 may be changed by providing a switch in the power supply line 22 and switching the switch. In addition, the connection state of the electrode 14 may be changed by providing the power supply line 22 on the substrate 10 and, for example, cutting a part of the power supply line 22.

  Further, a switch or the like may be provided in the cable 31 or the power supply device 30 outside the socket 7 and the connection state of the electrode 14 may be changed by switching the switch. For example, by switching the switches, the first electrode 14a and the second electrode 14b of the first power supply path 18a are electrically connected so that the first power supply path 18a and the second power supply path 18b are connected in parallel as shown in FIG. 6A. And the third electrode 14c and the fourth electrode 14d of the second power supply path 18b may be electrically connected. Further, as shown in FIG. 6B, the second electrode 14b of the first power supply path 18a and the third electrode 14c of the second power supply path 18b are connected so that the first power supply path 18a and the second power supply path 18b are connected in series. In addition, the first electrode 14a of the first power supply path 18a and the fourth electrode 14d of the second power supply path 18b may be electrically connected. FIG. 6A is a diagram illustrating a state in which the first power supply path 18a and the second power supply path 18b are connected in parallel in the lighting device 1 according to the modification. FIG. 6B is a diagram showing a state in which the first power supply path 18a and the second power supply path 18b are connected in series in the lighting device 1 according to the modification.

  Moreover, you may change the connection state of the electrode 14 by using the some socket 7 by which the connection state of the electrode 14 was changed. For example, the socket 7 to which the electrode 14 is electrically connected so as to connect the first power supply path 18a and the second power supply path 18b in parallel, and the first power supply path 18a and the second power supply path 18b are connected in series. The socket 7 to which the electrode 14 is electrically connected may be used depending on the application.

  Moreover, in the illuminating device 1 which concerns on the said embodiment, although the light emission color of the light emitting element 15 arrange | positioned at the 1st electric power feeding path 18a and the 2nd electric power feeding path 18b was demonstrated as an example, it is restricted to this. There is nothing. The light emission color of the light emitting element 15 arranged in the first power supply path 18a may be different from the light emission color of the light emitting element 15 arranged in the second power supply path 18b. That is, the substrate 10 may include a plurality of electrodes 14 that feed power to the light emitting elements 15 having different emission colors.

  Then, in the case of irradiating light with a light control toning method that changes the color and brightness of each light emitting element 15 having a different emission color, as shown in FIG. 7A, the first power supply line 22a and the second power supply line 22b and the 3rd electric power feeding line 22c are cut | disconnected. Thereby, the connection state of the electrode 14 is such that the first electrode 14a and the second electrode 14b of the first power feeding path 18a are electrically connected, and the third electrode 14c and the fourth electrode 14d of the second power feeding path 18b are electrically connected. It will be in the state which supplies power separately. FIG. 7A is a diagram illustrating a connection state of the electrodes 14 in the case of irradiating light with a light control and toning method in the illumination device 1 according to the modification. In this case, the power supply unit 21 supplies power from the power supply device 30a to the first power supply path 18a and supplies power from the power supply device 30b to the second power supply path 18b. That is, the power supply unit 21 supplies power to the first power supply path 18a from the power supply device 30a with the first predetermined voltage, and supplies power to the second power supply path 18b from the power supply device 30b with the second predetermined voltage. The first predetermined voltage and the second predetermined voltage are different predetermined voltages and are individually controlled voltages.

  In addition, when irradiating light by the Dim to Warm method in which the color and brightness of the light emitting elements 15 having different emission colors are changed, the third feeder line 22c is cut as shown in FIG. 7B. Thereby, the connection state of the electrode 14 is a state in which the first electrode 14a of the first power supply path 18a and the fourth electrode 14d of the second power supply path 18b are electrically connected to perform the same power supply. FIG. 7B is a diagram illustrating a connection state of the electrodes 14 when the illumination device 1 according to the modification irradiates light by the Dim to Warm method. In this case, the power supply unit 21 supplies power from the same power supply device 30 to the first power supply path 18a and the second power supply path 18b. That is, the power supply unit 21 supplies power to the first power supply path 18a and the second power supply path 18b with a common voltage.

  Thereby, even if it is the light emitting module 2 which has the light emitting element 15 from which luminescent color differs, the drive system can be changed and used according to a use using the same light emitting module 2. FIG. Therefore, it is not necessary to design and develop the light emitting module 2 for each application, and it is not necessary to manufacture a different member for each application, and the light emitting module 2, particularly the substrate 10, can be shared. Note that the power supply unit 21 may supply power to the first power supply path 18a and the second power supply path 18b as in the above modification even when the emission colors are the same color.

  In the light emitting module 2 according to the above embodiment, the substrate 10 provided with the four electrodes 14 and the socket 7 provided with the four power supply units 21 have been described as examples. However, the present invention is not limited thereto. The light emitting module 2 only needs to include three or more electrodes 14 and three or more power supply units 21.

The socket 7 includes a first power feeding unit 21e, a second power feeding unit 21f, and a third power feeding unit 21g. In the light emitting module 2 according to this modification, the first power supply path 18c and the second power supply path 18d are connected in series in the light emitter 6, and the third electrode 14g is connected to the first power supply path 18c and the second power supply path. It is electrically connected to the mounting pattern between 18d.

  In the light emitting module 2 according to the modification, for example, as illustrated in FIG. 9A, the first power supply unit 21e and the second power supply unit 21f are electrically connected to the power supply device 30 via the cable 31, and the first electrode 14e and The second electrode 14f is electrically connected.

FIG. 9B is a diagram illustrating a state where the first electrode 14e and the third electrode 14g are electrically connected in the light emitting module 2 according to the modification. For example, the third power feeding unit 21g and the second power feeding unit 21f may be electrically connected to the power supply device 30 via the cable 31, and the second electrode 14f and the third electrode 14g may be electrically connected. Further, for example, one of the cables 31 is connected to the third power feeding unit 21g, the other cable 31 is connected to the first power feeding unit 21e and the second power feeding unit 21f, and the first power feeding path 18c and the second power feeding path 18d. The third electrode 14g, the first electrode 14e, and the second electrode 14f may be electrically connected such that are connected in parallel.

  Thus, by providing three or more electrodes 14 and three or more power supply units 21, the connection state of the electrodes 14 can be changed with respect to the same light emitting module 2.

  Moreover, although the light emitting module 2 which concerns on the said embodiment is provided with the two electric power feeding paths 18 in the board | substrate 10, it is not restricted to this. The light emitting module 2 may include three or more power supply paths 18 on the substrate 10. Such a light emitting module 2 can change the connection state of the electrode 14 by, for example, cutting the power supply line 22. Therefore, similarly to the above-described embodiment, it is not necessary to design and develop the light emitting module 2 for each application, and it is not necessary to manufacture a different member for each application, and the light emitting module 2, particularly the substrate 10, can be shared.

  Moreover, in the said embodiment, although the socket 7 was demonstrated as an example of an electrical connector, it is not restricted to this. The electrical connector may be a connector that is electrically connected to the electrode 14 of the substrate 10. For example, the electrical connector may include an external cable 31, a switch, and the like in addition to the socket 7.

  Moreover, in the said embodiment, although the illuminating device 1 provided with the socket 7 was demonstrated as an example, it is not restricted to this. In the lighting device 1 according to the modification, the electrode 14 of the substrate 10 may be electrically connected by wiring (for example, an external cable) without using the socket 7. For example, the lighting device 1 according to the modification can change the connection state of the electrode 14 by cutting a part of the wiring or switching the switch.

  Moreover, although the said embodiment demonstrated the light emitting module 2 provided with the case 4, the glass cover 8, the elastic body 9, etc. as an example, it is not restricted to this.
