Title:
METHOD AND APPARATUS FOR A LAMP HOUSING
Document Type and Number:
WIPO Patent Application WO/2003/060378
Kind Code:
A3
Abstract:
A method and apparatus for a lamp housing (20) is provided that blocks light and dissipates heat. The lamp housing (20) encases or is integral to a reflector (12), and has an inner surface (30) that absorbs radiation emitted by the lamp burner and an outer surface (34) that allows for heat dissipation through radiation and convection means. The inner surface (30) absorbs radiation and the outer surface (34) is enlarged with a plurality of formations (22/24) for heat dissipation through radiation and convection means. The housing (20) also blocks stray visible light from escaping, thereby reducing or eliminating any need for light leakage systems.
