  • Method of varying luminous intensity of light in an illumination system
    Patent number: 5658070
    Abstract: A fiberoptic illumination system having an attenuator with a "multiple wedge" aperture that more uniformly attenuates the light beam striking the fiberoptic without changing the color temperature of the light beam or affecting the exit divergence angle of the light beam. The system includes an optical housing design having orthogonal lights paths that allows two fiberoptics to be illuminated from the same bulb, two bulbs located in primary and back-up positions, respectively, mounted on a rotating carousel and a retinal protection filter that filters out wavelengths of light harmful to the retina.
