Abstract
A cooling assembly particularly suitable for use with high brightness light sources requiring compact housing. The assembly comprises an air cooled heat sink and a connecting means being flexible and having a high thermal conductivity coefficient. This device provides an efficient method for cooling filament leads in the seal end of high brightness lamps and the joint between the lamp and reflector, thereby increasing lamp life.
Claims6
In combination,
- a. a high brightness incandescent lamp having an operating temperature and a seal end temperature substantially high in comparison to the corresponding temperature of inert gas incandescent lamps,
- b. means for dissipating heat from the seal end of said incandescent lamp comprising a mass of material having the heat conductivity characteristic thereof at least that of metals and of a quantity sufficient to prevent failure of the seal end region of said lamp, and
- c. flexible heat conductive adhesive means between said lamp seal end and said heat dissipating means for adhering said lamp and said heat dissipating means and for allowing expansion of said heat dissipating means and said lamp seal end without injury to the latter, said adhesive means comprising a flexible material of low heat conductivity combined with a material of high heat conductivity.
