Abstract
An ambient air cooled high intensity light emitting instrument in which the lamp is contained in a heat sink mounted within the housing. The housing contains a plurality of vent holes which circumscribe the heat sink. As heat from the light is conducted along the heat sink when the instrument is in use, the heat emanates into the chamber surrounding the heat sink, and rises through the vent holes to the surrounding atmosphere, generating a thermal current which replaces the departing hot air with cooler air from the atmosphere.
