Abstract
An excimer bulb assembly including a krypton/chlorine excimer bulb and a pass filter. The excimer bulb assembly does not emit substantial UV C radiation in wavelengths longer than deadly 240 nm through UV C wavelengths. The pass filter is adapted to block substantial UV C radiation in wavelengths in the range of 240 nm-280 nm. The assembly may include a captured reflector, a smart chip, and/or a heat sink. The bulb and its electrical connectors may form a cartridge. The assembly may include a housing and the cartridge may swivel in the housing.
Claims17
An excimer bulb assembly,
- comprising:
- a krypton/chloride excimer bulb;
- and
- a high pass filter, said high pass filter having a cutoff wavelength of 234 nm, and said high pass filter adapted to receive UV-C radiation from said krypton/chloride bulb with an incidence angle of zero degrees,
- wherein said excimer bulb and said high pass filter form a single unit such that said excimer bulb assembly does not emit substantial UV C radiation in wavelengths longer than 240 nm.

A replaceable excimer bulb cartridge,
- comprising:
- a krypton/chloride excimer bulb;
- a finned heat sink in thermal communication with said excimer bulb to conduct heat generated by said excimer bulb into the environment;
- and
- a high pass filter;
- said high pass filter adapted to block substantial UV C radiation in wavelengths in the range of 240 nm-280 nm,
- wherein said excimer bulb, said heatsink, and said high pass filter are integrated into the cartridge.
