Abstract
An excimer bulb fixture including an excimer bulb emitting a beam of UV light at a far UV C wavelength. The fixture includes a krypton/chloride bulb, a band pass filter and a diffusion layer or lens. The krypton/chloride bulb is adapted to project a beam of far UV C light through the filter and then through the diffusion layer or lens. The band pass filter is adapted to block substantial UV radiation wavelengths longer than 234 nm. The diffusion layer or lens is adapted to widen the beam of far UV C light. A method far widening a beam of far UV C light includes the steps of projecting a beam of far UV C light produced by a krypton/chloride bulb through a band pass filter; blocking substantially UV C radiation longer than 234 nm; projecting the filtered beam through a diffusion filter or lens; and, widening the filtered beam.
