Abstract: The assembly comprises a reflector housing subassembly incorporating a shell having a surface area for heat dissipation and a LED light source providing a prerequisite lumen output. A correlation of the surface area and the lumen output with a thickness of the shell, made generally of aluminum alloy, allows the shell to function as a heat sink. In the case of a conventional 6 in Pot Light, the assembly includes a reflector made of aluminum alloy with a gauge thickness of 1.5-1.63 mm. The LED light source is supplied by a 12 W power. For a parking garage area lightening assembly, a reflector with a bottom opening of 13 in×13 in and made of aluminum alloy with a gauge thickness of 1.5-1.63 mm is used. The LED light source has at least 2000 lumens and operates at least at 40 W.
