摘要:
A reflector providing directional control of visible and infra-red radiation emanating from a lamp held within the reflector. The reflector includes a first, optical interference coating applied to the interior surface of the dome-shaped portion of the reflector which is operable to transmit infra-red radiation while reflecting visible light. A second coating which is non-transmissive to IR radiation is applied to selected portions of the reflector body, and preferably to the area adjacent the neck portion of the reflector whereby components placed rearwardly of the reflector are protected from IR radiation. Various application techniques are disclosed, and the second coating may be applied in manners allowing for coding of reflectors of different types, as well as creating an aesthetically pleasing effect on surfaces illuminated by the IR radiation transmitted rearwardly of the reflector. Visible light escaping from the neck portion of prior art reflectors is also addressed by the present invention.
