Abstract

A clothing illumination device is switchable between illumination with visible light only and illumination with visible light mixed with ultraviolet light. The clothing illumination device also has an LED light source and an IC tag reader. A clothing illumination system has a first and a second clothing illumination device which are each switchable between illumination with visible light only and illumination with visible light mixed with ultraviolet light, and which operate in a fashion coordinated with each other to perform the switching.

Claims

1. A clothing illumination device configured to be capable of switching between illumination with visible light only and illumination with visible light mixed with ultraviolet light.

2. The clothing illumination device according to claim 1, comprising:

an LED light source capable of emitting visible light and ultraviolet light; and

a filter device capable of switching whether or not to cut an ultraviolet component of the LED light source.

3. The clothing illumination device according to claim 1, comprising:

a first LED light source capable of emitting visible light only; and

a second LED light source capable of emitting ultraviolet light,

wherein switching is possible as to whether or not to emit ultraviolet light from the second LED light source.

4. The clothing illumination device according to claim 3,

wherein the second LED light source is capable of emitting visible light and ultraviolet light.

5. The clothing illumination device according to claim 3,

wherein the first LED light source is arranged so as to illuminate an obverse side of clothing, and the second LED light source is arranged so as to illuminate the clothing from behind.

6. The clothing illumination device according to claim 1,

wherein switching is possible between illumination of colored clothes with visible light only and illumination of white clothes with visible light mixed with ultraviolet light.

7. The clothing illumination device according to claim 1, further configured to be capable of inhibiting illumination with ultraviolet light only.

8. The clothing illumination device according to claim 1, comprising an outside light detector,

wherein switching between illumination with visible light only and illumination with visible light mixed with ultraviolet light is done based on the outside light detector.

9. The clothing illumination device according to claim 1,

wherein switching between illumination with visible light only and illumination with visible light mixed with ultraviolet light is done according to time zone.

10. The clothing illumination device according to claim 1,

wherein switching between illumination with visible light only and illumination with visible light mixed with ultraviolet light is done according to where a piece of clothing to be illuminated is located.

11. The clothing illumination device according to claim 1,

wherein switching between illumination with visible light only and illumination with visible light mixed with ultraviolet light is done according to condition of illumination by another clothing illumination device.

12. The clothing illumination device according to claim 1, comprising an IC tag reader.

13. A clothing illumination system comprising a plurality of clothing illumination devices each according to claim 1,

wherein the clothing illumination devices operate in a fashion coordinated with one another so as to be individually switched between illumination with visible light only and illumination with visible light mixed with ultraviolet light.

14. A clothing illumination device comprising an LED light source and an IC tag reader.

15. A clothing illumination system comprising:

a first clothing illumination device configured to be capable of switching between illumination with visible light only and illumination with visible light mixed with ultraviolet light; and

a second clothing illumination device configured to be capable of switching between illumination with visible light only and illumination with visible light mixed with ultraviolet light,

wherein the first and second clothing illumination devices operate in a fashion coordinated with each other to perform the switching.

16. The clothing illumination system according to claim 15,

wherein, when the first clothing illumination device illuminates with visible light mixed with ultraviolet light, the second clothing illumination device illuminates with visible light only.

17. The clothing illumination system according to claim 15,

wherein the first clothing illumination device is an illumination device for a fitting room, and the second clothing illumination device is a ceiling illumination device.

18. The clothing illumination system according to claim 15,

wherein, when a white piece of clothing under illumination by the first clothing illumination device illuminating with visible light mixed with ultraviolet light is taken to under illumination by the second clothing illumination device, the second clothing illumination device is switched from illumination with visible light only to illumination with visible light mixed with ultraviolet light.

19. The clothing illumination system according to claim 18, comprising an outside light detector,

wherein, when the outside light detector detects a predetermined amount or more of outside light, illumination by the second clothing illumination device with visible light only is continued.

20. The clothing illumination system according to claim 18,

wherein, when a current time is outside opening hours, illumination by the second clothing illumination device with visible light only is continued.
