Abstract (en)
A light source for generating a specific wave length light including a bulb (13) containing a filament (14) for generating multiple wave length light, a coating (15a) on the surface of the bulb for reflecting certain wave lengths back into the bulb and for passing other wave lengths outside the bulb, a reflector (12) surrounding the bulb, a light reflecting surface (16a) mounted inside a portion of the reflector to reflect the specific wave length light impinging on it from the bulb outside the reflecting light source, wherein the light reflecting source is mounted at a location inside the reflector so that the specific wave length light impinging upon it is reflected, but other wave lengths of light emitted by the bulb do not impinge on it and are not reflected.
