Abstract

An illumination device includes a reception portion configured to receive a terminal ID stored by a radio terminal; a transmission portion configured to transmit the received terminal ID and a device ID; an illumination portion configured to emit light from a light source; and a housing portion configured to be detachably provided to the illumination portion and include a secondary battery capable of supplying power to the reception portion and the transmission portion.

First claim

What is claimed is:

1. An illumination device comprising:
at least one terminal, configured to receive power from an external source:
a reception portion configured to receive a terminal ID from a radio terminal;
a transmission portion configured to transmit the received terminal ID and a device ID of the illumination device, to another device;
an illumination portion, including at least one or more light sources, configured to receive power from the external source via the at least one terminal and to emit light; and
a housing portion, including a battery and configured to be separate from and detachably connectable to the illumination portion, the battery being configured to supply power to the reception portion and the transmission portion, at least in the absence of power being received via the at least one terminal.

2. The illumination device as claimed in claim 1 , wherein
the housing portion is configured to include at least one of the reception portion and the transmission portion.

3. The illumination device as claimed in claim 1 , wherein
the housing portion is configured to include have a light reflection member to reflect the light from the at least one or more light sources.

4. The illumination device as claimed in claim 1 , wherein
the reception portion is configured to receive the terminal ID by extremely low power radio.

5. The illumination device as claimed in claim 4 , wherein
the reception portion is configured to receive the terminal ID included in a beacon signal transmitted at each of plural intervals of time.

6. The illumination device as claimed in claim 4 , wherein
the transmission portion is configured to transmit the terminal ID and the device ID by a radio communication method different from the extremely low power radio.

7. The illumination device as claimed in claim 5 , wherein
the transmission portion is configured to transmit the terminal ID and the device ID by a radio communication method different from the extremely low power radio.

8. A communication system comprising:
the illumination device claimed in claim 1 ; and
a management apparatus configured to manage a position of the radio terminal, wherein
the transmission portion of the illumination device is configured to transmit the terminal ID and the device ID to the management apparatus.

9. The communication system as claimed in claim 8 , wherein
a housing portion of the illumination device is configured to include at least one of the reception portion and the transmission portion.

10. The communication system as claimed in claim 8 , wherein
the housing portion of the illumination device is configured to have a light reflection member reflecting the light from the at least one or more light sources.

11. The communication system as claimed in claim 8 , wherein
the reception portion of the illumination device is configured to receive the terminal ID by extremely low power radio.

12. The communication system as claimed in claim 11 , wherein
the reception portion of the illumination device is configured to receive the terminal ID included in a beacon signal transmitted at each of plural intervals of time.

13. The communication system as claimed in claim 11 , wherein
the transmission portion of the illumination device is configured to transmit the terminal ID and the device ID by a radio communication method different from the extremely low power radio.

14. The communication system as claimed in claim 12 , wherein
the transmission portion of the illumination device is configured to transmit the terminal ID and the device ID by a radio communication method different from the extremely low power radio.

15. The communication system as claimed in claim 8 , further comprising:
a relay apparatus configured to relay the terminal ID and the device ID transmitted from the transmission portion.

16. The illumination device as claimed in claim 1 , wherein the battery is configured to supply power to and maintain operation of the reception portion and the transmission portion, independent of power externally supplied to the illumination portion.

17. The illumination device as claimed in claim 1 , wherein the at least one terminal is configured to supply the externally supplied power to at least the illumination portion, the battery being configured to store externally supplied power and to supply power to the reception portion and the transmission portion, at least in the absence of the externally supplied power.

18. The illumination device as claimed in claim 1 , wherein illumination portion includes a plurality of light sources capable of generating heat, and wherein the battery is separate from the plurality of heat generating light sources of the illumination portion.

19. A communication system comprising:
the illumination device claimed in claim 17 ; and
a management apparatus configured to manage a position of the radio terminal, wherein
the transmission portion of the illumination device is configured to transmit the terminal ID and the device ID to the management apparatus.

20. A communication system comprising:
the illumination device claimed in claim 18 ; and
a management apparatus configured to manage a position of the radio terminal, wherein
the transmission portion of the illumination device is configured to transmit the terminal ID and the device ID to the management apparatus.
