PORTABLE LIGHT HAVING A HEAT DISSIPATER WITH AN INTEGRAL COOLING DEVICE

摘要

A portable light or device (10, 10', 10", 10"') or heat dissipater (200, 200', 200', 200'") may comprise a heat sink (210, 210', 210', 210"') for having a light source (240) or other heat generating element (240) thermally coupled thereto, and having a plurality of walls (211-215, 211 "'-215"', 1211) extending from a side thereof for defining a cavity and plural passages, a fluid mover (220, 220"') in the cavity of the heat sink (210, 210', 210', 210'") for selectively causing a fluid to move through the cavity and the plural passages, and a light source (240) or other heat generating element (240) adjacent to and thermally coupled to the heat sink (210, 210', 210', 210'"). The heat dissipater (200, 200', 200', 200"') may be connected to a housing (20, 20') in various configurations.
