Abstract

A system for improving an appearance of light from an excimer lamp includes the excimer lamp configured to output excimer light that includes ultraviolet light having an ultraviolet wavelength and visible light having a first visible wavelength or spectra. The system further includes at least one additional light source configured to be packaged with the excimer lamp and to output additional light having a second visible wavelength or spectra. The system further includes a cover that is at least one of transparent or translucent to the ultraviolet wavelength and having a surface pattern that causes the excimer light to blend with the additional light.

First claim

What is claimed is:

1. A system for improving an appearance of light from an excimer lamp, the system comprising:
the excimer lamp configured to output excimer light that includes ultraviolet light having an ultraviolet wavelength and visible light having a first visible wavelength or spectra;
at least one additional light source configured to be packaged with the excimer lamp and to output additional light having a second visible wavelength or spectra; and
a cover that is at least one of transparent or translucent to the ultraviolet wavelength and having a surface pattern that causes the excimer light to blend with the additional light.

2. The system of claim 1 , wherein the ultraviolet wavelength of the ultraviolet light that is output by the excimer lamp is between 200 and 225 nanometers.

3. The system of claim 1 , wherein the excimer lamp includes a plurality of excimer lamps spaced apart, and the at least one additional light source includes a plurality of additional light sources interspersed with the plurality of excimer lamps.

4. The system of claim 1 , wherein a combination of the excimer light and the additional light appears white to a human eye.

5. The system of claim 1 , wherein the second visible wavelength or spectra is selected to cause a combination of the visible light having the first visible wavelength or spectra and the additional light having the second visible wavelength or spectra to appear white to a human eye.

6. The system of claim 1 , wherein the at least one additional light source includes at least two additional light sources that each output the additional light having a different visible wavelength such that a combination of the additional light that is output by the at least two additional light sources appears white to a human eye.

7. The system of claim 1 , wherein a second luminescence of the additional light is at least one order of magnitude greater than a first luminesce of the visible light that is output by the excimer lamp so as to mask the visible light that is output by the excimer lamp.

8. The system of claim 1 , wherein the cover includes a quartz glass.

9. The system of claim 8 , wherein the quartz glass is etched to have the surface pattern.

10. A system for improving an appearance of light from an excimer lamp, the system comprising:
the excimer lamp configured to output excimer light that includes ultraviolet light having an ultraviolet wavelength and visible light having a first visible wavelength or spectra;
at least one additional light source configured to be packaged with the excimer lamp and to output additional light having a second visible wavelength or spectra;
a casing having an outlet;
a first reflector configured to reflect the excimer light and the additional light towards the outlet; and
a second reflector configured to reflect the excimer light and the additional light from the first reflector, from the excimer lamp, and from the at least one additional light source out of the outlet, the second reflector configured to reflect the ultraviolet light.

11. The system of claim 10 , wherein the second reflector has a polytetrafluoroethylene (PTFE) coating.

12. The system of claim 10 , wherein the excimer lamp and the casing each have an elongated shape, and the at least one additional light source includes an array of light sources spaced along a length of the casing.

13. The system of claim 10 , wherein the ultraviolet wavelength of the ultraviolet light that is output by the excimer lamp is between 200 and 225 nanometers.

14. The system of claim 10 , wherein a combination of the excimer light and the additional light appears white to a human eye.

15. The system of claim 10 , wherein the second visible wavelength or spectra is selected to cause a combination of the visible light having the first visible wavelength or spectra and the additional light having the second visible wavelength or spectra to appear white to a human eye.

16. The system of claim 10 , wherein the at least one additional light source includes at least two additional light sources that each output the additional light having a different visible wavelength such that a combination of the additional light that is output by the at least two additional light sources appears white to a human eye.

17. The system of claim 10 , wherein a second luminescence of the additional light is at least one order of magnitude greater than a first luminesce of the visible light that is output by the excimer lamp so as to mask the visible light that is output by the excimer lamp.

18. A method for improving an appearance of light from an excimer lamp, the method comprising:
outputting, by the excimer lamp, excimer light that includes ultraviolet light having an ultraviolet wavelength and visible light having a first visible wavelength or spectra;
outputting, by at least one additional light source, additional light having a second visible wavelength or spectra; and
blending the excimer light with the additional light to hide the visible light having the first visible wavelength or spectra that is output by the excimer lamp.

19. The method of claim 18 , wherein blending the excimer light with the additional light includes diffusing, by a quartz glass cover, the excimer light and the additional light.

20. The method of claim 18 , wherein blending the excimer light with the additional light includes blending, using at least one reflector configured to reflect the excimer light, the excimer light and the additional light prior to a combination of the excimer light and the additional light leaving an outlet.
