Patent ID: 7108504

Claim:
A light for activating light-activated materials comprising: a wand adapted to be grasped by a human hand for use in positioning and manipulating the light, a wand housing that is at least a portion of the exterior surface of said wand, said wand housing having a top, a bottom, a left side and a right side, an elongate heat sink located at least partially within said wand, said elongate heat sink having a proximal end, a distal end, and a longitudinal axis therebetween, a mounting platform on said elongate heat sink distal end, at least one semiconductor chip capable of emitting light of a wavelength that is useful in activating light-activated materials, said semiconductor chip being located on said mounting platform at said elongate heat sink distal end, said mounting platform being oriented so that light emitted directly in front of said chip travels at an angle of 30 to 150 degrees with respect to said longitudinal axis, a cover for covering said chip, said cover being made at least in part from a material that permits light emitted by said chip to pass through said cover to travel to a light-activated material, a plurality of air vents on said housing, a plurality of insulators located between said heat sink and said wand housing, an air jacket located between said heat sink and said housing, said air jacket being maintained by said insulators keeping said housing spaced apart from said elongate heat sink, said air jacket at least partially surrounding said heat sink, said air jacket permitting air circulation, ventilation and heat dissipation in order to manage heat given off by said chip, said circulation occurring by air entering an air vent, passing through said air jacket where said air picks up heat from said elongate heat sink, and said air departing through an air vent to the exterior of said housing in order to dissipate heat from said elongate heat sink.
