Abstract

There is provided a light-emitting device including a wireless communication unit that performs wireless communication with another device, a light-emitting unit that emits light, and a control unit that performs control by switching between a mode in which the light emission of the light-emitting unit is controlled in accordance with a timing at which a signal is received by the wireless communication unit and a mode in which the light emission of the light-emitting unit is controlled in accordance with an internal timer based on a light emission timing included in a signal received from the other device by the wireless communication unit.

2. The light-emitting device according to claim 1, wherein the broadcast mode and the ID separation mode are modes in which the another device transmits a driving signal and controls the light-emitting device.

3. The light-emitting device according to claim 1, wherein the broadcast mode is a mode in which the light-emitting unit is controlled the same as all other light-emitting devices in a predetermined area.

4. The light-emitting device according to claim 3, wherein the control of the light-emitting unit includes emission color, luminance, and turn-on/off time.

5. The light-emitting device according to claim 1, wherein the ID separation mode is a mode in which the light-emitting device is controlled differently than other light-emitting devices within a predetermined area for each ID allocated to each light-emitting device.

6. The light-emitting device according to claim 5, wherein control of the ID separation mode is performed so that emission color, luminance and turn-on/off time is different for each light-emitting device in the predetermined area.

7. The light-emitting device according to claim 1, wherein an acquire unit acquires a user'"'"'s operation of the light-emitting device.

8. The light-emitting device according to claim 1, further including a manual mode.

9. The light-emitting device according to claim 8, wherein the manual mode is started after the light-emitting device is turned on.

10. The light-emitting device according to claim 1, wherein the control unit performs control by switching between a mode in which the light emission of the light-emitting unit is controlled based on a signal received by the wireless communication unit, and a mode in which the light-emitting unit, in accordance with an input to a user operation based on whether the wireless communication unit receives a signal from the another device within a predetermined time.

11. A light-emitting method for a light-emitting device comprising the steps of:

a wireless communication step that performs wireless communication with another device;

a light-emitting step that emits light by a light-emitting unit; and

a control step configured to perform control by switching between a mode in which light emission of the light-emitting unit is a broadcast mode and a mode in which the light emission of the light-emitting unit is an ID separation mode.

12. The light-emitting method according to claim 11, wherein the broadcast mode is a mode in which all light-emitting devices within a predetermined area are controlled the same.

13. The light-emitting method according to claim 12, wherein the control of the light-emitting device includes emission color, luminance, and turn-on/off time.

14. The light-emitting method according to claim 11, wherein the broadcast mode and the ID separation mode are modes in which the another device transmits a driving signal and controls the light-emitting device.

15. The light-emitting method according to claim 11, wherein the ID separation mode is a mode in which the light-emitting device is controlled differently than other light-emitting devices within a predetermined area for each ID allocated to each light-emitting device.

16. The light-emitting method according to claim 15, wherein control of the ID separation mode is performed so that emission color, luminance and turn-on/off time is different for each light-emitting device in the predetermined area.

17. The light-emitting method according to claim 11, wherein an acquire unit acquires a user'"'"'s operation of the light-emitting device.

18. The light-emitting method according to claim 11, further including a manual mode.

19. The light-emitting method according to claim 18, wherein the manual mode is started after the light-emitting device is turned on.

20. The light-emitting method according to claim 11, wherein the control step performs control by switching between a mode in which the light emission of the light-emitting unit is controlled based on a signal received by a wireless communication unit, and a mode in which the light-emitting unit, in accordance with an input to a user operation based on whether the wireless communication unit receives a signal from the another device within a predetermined time.

21. A computer program embodied on a non-transitory-computer readable medium for a light-emitting device comprising the steps of:
