Abstract

An illumination system includes a plurality of illumination apparatuses including a sleeping location illumination apparatus provided near a sleeping location. Each of the illumination apparatuses has a light source configured to irradiate an illumination light, a control unit configured to control lighting of the light source, and a transceiver configured to transmit and receive a control signal including a lighting signal for lighting the light source. A control unit of at least one of the illumination apparatuses turns on the light source before a preset wake-up time and controls the transceiver to transmit the control signal to another illumination apparatus.

Claims

1. An illumination system comprising:

a plurality of illumination apparatuses including a sleeping location illumination apparatus provided near a sleeping location,

wherein each of the illumination apparatuses has a light source configured to irradiate an illumination light, a central processing unit (CPU) configured to control lighting of the light source, and a transceiver configured to transmit and receive a control signal including a lighting signal for lighting the light source,

wherein, in at least one of the illumination apparatuses, the CPU turns on the light source before a preset wake-up time and controls the transceiver to transmit the control signal to another illumination apparatus,

wherein the control signal includes attribute information of the at least one of the illumination apparatuses,

wherein, before the preset wake-up time, each of the illumination apparatuses transmits and receives the control signal and sets respective lighting start times based on the attribute information, and

wherein the attribute information includes at least one of information on a distance from each of the illumination apparatuses to the sleeping location, lighting output information of each of the illumination apparatuses, and light distribution information of each of the illumination apparatuses.

2. The illumination system of claim 1, wherein the attribute information includes the information on the distance from each of the illumination apparatuses to the sleeping location.

3. The illumination system of claim 2, wherein the attribute information further includes the lighting output information of each of the illumination apparatuses.

4. The illumination system of claim 3, wherein the attribute information further includes the light distribution information of each of the illumination apparatuses.

5. The illumination system of claim 3, wherein at least one of the illumination apparatuses further includes a sensor configured to detect a user'"'"'s sleeping state,

wherein the control signal further includes detection information of the sensor, and

wherein the plurality of illumination apparatuses sets respective lighting start times based on the detection information.

6. The illumination system of claim 3, wherein at least one of the illumination apparatuses includes an input for setting the preset wake-up time,

wherein the input configured to allow two or more the preset wake-up times to be set.

7. The illumination system of claim 2, wherein the attribute information further includes the light distribution information of each of the illumination apparatuses.

8. The illumination system of claim 2, wherein at least one of the illumination apparatuses further includes a sensor configured to detect a user'"'"'s sleeping state,

wherein the control signal further includes detection information of the sensor, and

wherein the plurality of illumination apparatuses sets respective lighting start times based on the detection information.

9. The illumination system of claim 2, wherein at least one of the illumination apparatuses includes an input for setting the preset wake-up time,

wherein the input configured to allow two or more the preset wake-up times to be set.

10. The illumination system of claim 1, wherein the attribute information includes the lighting output information of each of the illumination apparatuses.

11. The illumination system of claim 10, wherein the attribute information further includes the light distribution information of each of the illumination apparatuses.

12. The illumination system of claim 10, wherein at least one of the illumination apparatuses further includes a sensor configured to detect a user'"'"'s sleeping state,

wherein the control signal further includes detection information of the sensor, and

wherein the plurality of illumination apparatuses sets respective lighting start times based on the detection information.

13. The illumination system of claim 10, wherein at least one of the illumination apparatuses includes an input for setting the preset wake-up time,

wherein the input configured to allow two or more the preset wake-up times to be set.

14. The illumination system of claim 1, wherein the attribute information includes the light distribution information of each of the illumination apparatuses.

15. The illumination system of claim 1, wherein at least one of the illumination apparatuses further includes a sensor configured to detect a user'"'"'s sleeping state,

wherein the control signal further includes detection information of the sensor, and

wherein the plurality of illumination apparatuses sets respective lighting start times based on the detection information.

16. The illumination system of claim 1, wherein at least one of the illumination apparatuses includes an input for setting the preset wake-up time,

wherein the input configured to allow two or more the preset wake-up times to be set.

17. An illumination apparatus used for the illumination system described in claim 1.
