Abstract
A vehicle lamp assembly includes a light source unit (e.g., one or more LEDs) mounted to an associated vehicle for providing illumination and a heat sink thermally coupled to the light source unit for dissipating generated heat therefrom. The heat sink has a main body portion, spaced apart fins extending from the main body portion, and an angled surface section on the main body portion disposed between adjacent ones of the spaced apart fins for urging environmental elements to run off the heat sink.

7. A vehicle lamp assembly comprising:
-
a light source unit mounted to an associated vehicle for providing illumination; and a heat sink thermally coupled to said light source unit for dissipating generated heat therefrom, said heat sink having a main body portion, spaced apart fins extending from said main body portion, and an angled surface section on said main body portion disposed between adjacent ones of said spaced apart fins for urging environmental elements to run off said heat sink; said main body portion including a lower surface from which said fins extend and an opposite surface formed on a side of said main body portion opposite said lower surface, wherein said angled surface section is a portion of said lower surface disposed between adjacent ones of said spaced apart fins, and wherein said lower surface and said angled surface section are formed in a plane oriented at an acute angle relative to a plane in which said opposite surface is formed. - View Dependent Claims (2, 8, 9, 10, 24, 25)

11. A LED lamp assembly for a vehicle, comprising:
-
a lamp housing mounted to an associated vehicle; a LED light source unit operatively mounted to said lamp housing; a heat sink mounted on an exterior of said lamp housing for dissipating heat generated from said LED light source unit, said heat sink including a main body portion and heat dissipating fins upstanding from said main body portion, angled surface sections disposed between each adjacent pair of said heat dissipating fins that are oriented acutely relative to a normal direction of gravity for promoting run off of environmental elements received thereon. - View Dependent Claims (6, 14, 15, 26)

21. A vehicle lamp assembly having a LED light source unit, comprising:
-
a lamp housing of an associated vehicle; a LED light source unit operatively mounted in said lamp housing for providing illumination; and a heat sink thermally connected to said light source unit and mounted to an exterior of said lamp housing so as to be exposed to the environment, said heat sink including; a main body portion having a lower surface; an opposite surface formed on a side of said main body portion opposite said lower surface, said lower surface oriented at an acute angle relative to said opposite surface, spaced apart fins extending upwardly from said lower surface of said main body portion for dissipating heat generated by said light source unit, and surface sections of said lower surface defined between adjacent ones of said spaced apart fins, said surface sections angularly oriented relative to a horizontal plane for urging and promoting environmental elements off of said heat sink. - View Dependent Claims (19)
