Patent ID: 8632210

Claim:
A light emitting assembly ( 10 ) comprising; a heat sink ( 12 ) presenting a mounting surface ( 20 ) and an oppositely facing heat transfer surface ( 22 ), said heat sink ( 12 ) including a plurality of independent sections ( 14 ) each presenting side edges ( 16 ) extending between opposite end edges ( 18 ), a plurality of light emitting diodes ( 52 ) (LEDs) disposed on said mounting surface ( 20 ) of said sections ( 14 ), each of said sections ( 14 ) including walls ( 24 , 26 ) extending transversely from said mounting surface ( 20 ) about said side edges ( 16 ) and said end edges ( 18 ) so that each of said mounting surfaces ( 20 ) and surrounding walls ( 24 , 26 ) define an open container with said light emitting diodes ( 52 ) and said mounting surface ( 20 ) at the bottom of said open container, and characterized by each of said sections ( 14 ) including a plurality of first fins ( 32 ) extending outwardly from said walls ( 24 , 26 ) and disposed in spaced relationship to one another for transferring heat away from said sections ( 14 ) to surrounding ambient air, and a support means ( 36 ) extending longitudinally across said sections ( 14 ) for supporting said sections ( 14 ) in spaced relationship to one another with said first fins ( 32 ) of adjacent sections ( 14 ) extending toward one another in the space between sections ( 14 ).
