LED light

摘要

There is disclosed a LED light (10) including a lower housing (14), an upper housing (15), and a thermally insulative base gasket (16). The upper housing has a top wall (31) with a central mounting area (35) and a peripheral margin. The wall thickness of the central mounting area is thicker than that of the peripheral margin (38). The upper housing also includes a plurality of heat dissipating ribs (41) extending between the mounting area and the sidewalls. The ribs increase in height as they extend outwardly toward the sidewalls. The lighting portion includes a LED light array (37), a lens (48), and a lens gasket (49). With the LED array mounted to the central mounting area, heat generated by the LED array is conveyed to the central mounting area and then conveyed through the upper housing top wall and ribs to the sidewalls.

主权项

1. A LED light for a cold room environment comprising,
a housing having at least a thermally conductive top wall and peripheral sidewalls, said top wall having a top surface, a bottom surface, a central region with a first wall thickness between said top surface and said bottom surface, and a peripheral margin extending between said central region and said peripheral sidewalls with a second wall thickness between said top surface and said bottom surface smaller than said central region first wall thickness; a plurality of LED light elements mounted in thermal contact with said top surface of said top wall in said central region; a lens coupled to said housing and covering said plurality of LED light elements, and a power supply circuit positioned within said housing and electrically coupled to said LED light elements, whereby the housing central region is a heat sink which conducts heat away from the plurality of LED light elements.
