Abstract
An excimer bulb assembly, with an excimer bulb, at least one integral captured reflector, and an integral filter such that the excimer bulb only emits substantial UV radiation between 200 nm and 230 nm, using a filter that passes light from about 200 nm to 234 nm (+/−2 nm).
Claims22
An excimer fixture, comprising:
- a krypton/chlorine excimer bulb emitting UV radiation substantially in a far UV C frequency range;
- a power supply for providing electrical power to the krypton/chlorine excimer bulb;
- said power supply adapted for dimming the krypton/chlorine excimer bulb.
A method of providing power to an excimer bulb emitting UV radiation substantially in a far UV-C frequency range, the method comprising:
- providing electrical power to the excimer bulb by a power supply;
- dimming the excimer bulb using said power supply;
- controlling said power supply with a processor
- sensing objects in the proximity of the excimer bulb with a proximity sensor;
- instructing said power supply to provide electrical power to the excimer bulb such that said bulb emits UV radiation based upon the proximity of objects in the proximity of the excimer fixture as sensed by said crowd density sensor;
- sensing the distance between the excimer bulb and a surface using a distance sensor;
- instructing said power supply to provide electrical power to the excimer bulb such that said bulb emits UV radiation based upon the distance of the excimer fixture and said surface as said distance is sensed by said distance sensor.

An excimer fixture including an excimer bulb emitting UV radiation substantially in a far UV-C frequency range, comprising:
- a power supply for providing electrical power to the excimer bulb;
- said power supply adapted for dimming the excimer bulb;
- a crowd density sensor in communication with said processor;
- said crowd density sensor adapted for sensing the number of people in a given area;
- said processor adapted for instructing said power supply to provide electrical power to the excimer bulb such that said bulb emits UV radiation based upon the number of people in a given area sensed by said crowd density sensor.
An excimer fixture including an excimer bulb emitting UV radiation substantially in a far UV-C frequency range, comprising:
