LED SPHERICAL LIGHT FIXTURES WITH ENHANCED HEAT DISSIPATION

摘要

An underwater light fixture (100) comprises an at least partially spherical thermally conductive housing (110, 120) having a hollow interior and a first aperture at a front side of the housing (110, 120). A transparent window (112) extends across the first aperture. A seal (232) between a periphery of the window (112) and the front body provides resistance to the entry of water into the hollow interior of the housing (110, 120). An LED driver circuit is positioned in the housing interior. At least one LED is mounted on an LED printed circuit board (PCB) and disposed behind the rear side of the window (112).
