Abstract

Provided is an illumination device which can be used in a manner suitable for the condition. The exchange time information to be acquired from an LED illumination lamp by an illumination instrument or the exchange time information to be stored by the illumination instrument itself is recognized by a controller at and via an ON/OFF control-dedicated switch control line of the LED illumination lamp. Alternatively, the acquisition of the exchange time information and ON/OFF-control of the LED illumination lamp are performed by the controller at hand via a general-purpose power line. The exchange time information is acquired from the illumination instrument in an OFF period of the LED illumination lamp, so that the exchange information can be acquired by simple information transmission means regardless of the ON-period noise. The exchange time information acquisition function is checked on a daily basis so as to cope with an alarm after a long period. The exchange time check result is stored so as to execute the alarm at an appropriate timing. The exchange time information held by the LED illumination lamp itself is transmitted firstly to the illumination instrument by simple information transmission means. The information is recognized by using a control path existing between the illumination instrument and the controller at hand.

Claims

1. An illumination device comprising:

an illumination instrument whose light source is an LED illumination lamp; and

a remote controller which remotely controls turn-on of the LED illumination lamp and remotely receives information about exchange time of the LED illumination lamp from the illumination instrument.

2. An illumination device according to claim 1, wherein the illumination instrument includes a storage unit which stores the information about exchange time of the LED illumination lamp.

3. An illumination device according to claim 2, wherein the LED illumination lamp is detachable from the illumination instrument, and the storage unit stores the information about exchange time when the LED illumination lamp is attached.

4. An illumination device according to claim 1, wherein the LED illumination lamp is detachable from the illumination instrument, and the illumination instrument includes an acquiring unit which acquires the information about exchange time stored in the LED illumination lamp from the LED illumination lamp.

5. An illumination device according to claim 1, wherein a control route from the remote controller to the illumination instrument is shared as a transmission route of the information about exchange time of the LED illumination lamp from the illumination instrument to the receiving unit.

6. An illumination device according to claim 5, wherein the control route and the transmission route are a power line.

7. An illumination device according to claim 5, wherein the control route is a switch control signal transmission route for controlling on and off of the LED illumination lamp, and the switch control signal transmission route is shared as the transmission route for the information about exchange time of the LED illumination lamp.

8. An illumination device according to claim 1, wherein the LED illumination lamp is detachable from the illumination instrument, and the illumination instrument includes a storage unit which stores the information about exchange time of the LED illumination lamp, a control unit which controls the storage unit to store the information about exchange time when the LED illumination lamp is attached, and a transmitting unit which transmits externally the information about exchange time of the LED illumination lamp stored in the storage unit.

9. An illumination device according to claim 1, wherein the LED illumination lamp is detachable from the illumination instrument, and the illumination instrument includes an acquiring unit which acquires the information about exchange time stored in the LED illumination lamp from the LED illumination lamp, and a transmitting unit which transmits externally the information about exchange time of the LED illumination lamp acquired by the acquiring unit.

10. An illumination device according to claim 1, wherein the remote controller includes a display unit which performs a display based on the information about exchange time of the LED illumination lamp that is received.

11. An illumination device according to claim 10, wherein the display unit performs a display based on the information about exchange time of the LED illumination lamp in association with remote control of turn-on of the LED illumination lamp.

12. An illumination device according to claim 1, wherein the remote controller receives the information about exchange time of the LED illumination lamp from the illumination instrument during an OFF period of the LED illumination lamp.

13. An illumination device according to claim 12, wherein the remote controller controls the LED illumination lamp to be in an OFF state before the receiving unit receives the information about exchange time of the LED illumination lamp.

14. An illumination device according to claim 12, wherein the remote controller controls the LED illumination lamp to be in an ON state after the receiving unit receives the information about exchange time of the LED illumination lamp.

15. An illumination device comprising:

an illumination instrument whose light source is an LED illumination lamp; and

a controller including a receiving unit which receives information about exchange time of the LED illumination lamp from the illumination instrument and a checking unit which automatically checks a function of the receiving unit.

16. An illumination device according to claim 15, wherein the controller includes a control unit which remotely controls turn-on of the LED illumination lamp, and automatically receives the information about exchange time of the LED illumination lamp from the illumination instrument in association with turn-on control of the LED illumination lamp by the control unit.

17. An illumination device according to claim 15, wherein the controller includes a display unit which displays a result of the automatic checking of the function of the receiving unit.

18. An illumination device comprising:

an illumination instrument whose light source is an LED illumination lamp; and

a controller including a receiving unit which receives information about exchange time of the LED illumination lamp from the illumination instrument during an OFF period of the LED illumination lamp.

19. An illumination device according to claim 18, wherein the controller includes a control unit which controls the LED illumination lamp to be in an OFF state before the receiving unit receives the information about exchange time of the LED illumination lamp.

20. An illumination device according to claim 18, wherein the controller includes a control unit which controls the LED illumination lamp to be in an ON state after the receiving unit receives the information about exchange time of the LED illumination lamp.
