Electric lamp having reflector for transferring heat from light source

摘要

The invention relates to an electric lamp (102) comprising a primary semiconductor light source (104) in thermal communication with a primary reflector (106). Herein, the primary reflector (106) is reflective, transparent and/or translucent. The primary reflector (106) is configured for transferring heat generated by the primary semiconductor light source (104) during operation away from said primary semiconductor light, source (104). As a result, the electric lamp (102) according to the invention effectively reduces the number of parts comprised in the electric lamp (102), thereby lowering the costs of manufacturing the electric lamp (102).

主权项

1. An electric lamp, comprising:
a primary semiconductor light source having a primary optical axis and positioned in thermal communication with and mounted to a primary reflector, a printed circuit board for facilitating thermal communication between the primary semiconductor light source and the primary reflector, wherein the primary reflector is plate-like in shape, extending in a predetermined plane that is transverse to said primary optical axis, and is reflective, transparent and/or translucent, and configured for transferring heat generated by the primary semiconductor light source during operation away from said primary semiconductor light source, a transparent optical chamber for encompassing at least the primary semiconductor light source, and enclosing a first unfilled volume and a second unfilled volume such that the first volume extends in a direction parallel to the primary optical axis and the second volume extends in a direction opposing from the direction of the first volume, the transparent optical chamber arranged on the primary reflector such that the plate-like primary reflector is arranged between the first and second volumes of the transparent optical chamber.
