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).
Claims20
An excimer fixture, comprising:
- a krypton/chlorine excimer bulb emitting UV radiation substantially in a far UV C wavelength range;
- a power supply for providing electrical power to the krypton/chlorine excimer bulb to produce far UV C at a first intensity, said electrical power comprising a pulse train;
- said power supply adapted for dimming the krypton/chlorine excimer bulb to produce far UV C at a second intensity which is less than said first intensity by varying a characteristic of said pulse train.
An excimer fixture including an excimer bulb emitting UV radiation substantially in a far UV-C wavelength range, comprising:
- a power supply for providing electrical power to the excimer bulb;
- said power supply adapted for dimming the excimer bulb such that the excimer bulb will selectively emit radiation at either a first intensity or a second intensity different from said first intensity;
- a processor adapted for communication with said power supply;
- 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.
