ABSTRACT:
A compact, lightweight illumination system for producing a uniform, intense, and adjustable light beam. The illumination assembly may be easily mounted upon the head of a user, either on a headband or a spectacle frame. The illumination system includes a unique optical subassembly consisting of a low pass heat filter, a low scatter angle diffuser, and a compound projection/focussing lens sandwiched together and disposed along an optical axis. The optical subassembly may be used in conjunction with a conventional filament lamp illumination source to produce a readily adjustable, yet uniform and intense, beam of light.
