Abstract
Abstract A fiber optics light source of compact, flat configuration comprises a narrow lamphouse including lamp, reflector and condenser aligned for focusing into the receiving end of a fiber optics bundle, and an air impeller mounted laterally of the lamphouse to direct air over the lamp for dissipating heat buildup. The light source may be built into a dental chair or the like, or it may be a separate module.

Claim 1
Independent Claim
362 words
A compact, high-intensity light source for a fiber optics illumination system, comprising: a. a case having protrusions therein for mounting a lamphouse, and defining apertures in the walls of said case for receiving air, for expelling air, and for light egress; b. a lamphouse disposed within said case, and being demountable therefrom, comprising: 1. a narrow mounting bracket having slots corresponding to said protrusions in said case, said mounting bracket being formed sealably with said case and defining an aperture for the passage of air; 2. a socket disposed upon said mounting bracket for mounting and positioning a high-intensity lamp; 3. a high-intensity lamp having a filament and a narrow envelope; 4. a reflector mounted in optical alignment with said highintensity lamp for reflecting light back toward the filament of said lamp; 5. an optical condenser lens mounted in optical alignment with said lamp, socket and reflector and focusing light from said lamp through said light egress aperture of said case; 6. a housing mounted upon said mounting bracket for holding said reflector and said condenser, said housing defining a lamp chamber connecting with said mounting bracket at said air passage aperture, and connecting with said case at said air expelling aperture; 7. a heat baffle mounted upon said housing within said lamp chamber for receiving heat from said lamp, said heat baffle comprising a sheet metal member depending from said housing to define an aperture across said lamp chamber for the passage of air around said sheet metal member to carry off heat therefrom through said air expelling aperture; c. a flatly formed air impeller disposed within said case laterally from said lamphouse and adjacent to said air receiving aperture; d. a fan scroll sealably disposed within said case around said air impeller and extending spirally toward said air passage aperture of said lamphouse mounting bracket, for guiding air from said air impeller to said air passage aperture; and e. coupling means on said case for coupling a fiber optics illumination conduit to said case at said light egress aperture; whereby said components are disposed to supply high-intensity light to said fiber optics illumination conduit while dispersing heat from said lamp.
