Abstract: Pursuant to some embodiments, a high mast luminaire includes a driver housing and a light engine assembly comprising a light engine housing which includes a circumferential wall, the light engine housing comprising an interior space in which a plurality of LED light engines are located, wherein the light engine housing includes a plurality of air flow channels on a radially outer side of the wall, and wherein the air flow channels are separated from the plurality of LED light engines by the circumferential wall.

Abstract: A light emitting diode (LED) package according to various embodiments can include a metal substrate having a surface roughness. A thin film coated reflector is applied to the metal substrate. At least one light emitting diode (LED) chip is mounted above at least a portion of the metal substrate.

Abstract: Provided is a multi-layer reflective coating for application to a lighting housing assembly, including a polymer substrate adjacent a polymer base coat layer applied to the lighting housing. Atop the polymer base coat layer is an aluminum adhesion layer, followed by a diffusive barrier layer, and a silver reflective layer. The aluminum adhesion layer promotes adhesion between the polymer base coat layer and the silver reflective layer. The diffusive barrier layer prevents aluminum and silver interaction, which could form a silver and aluminum alloy. A spectrum tunable layer is applied atop the silver reflective layer for spectrum tuning the silver reflective layer for maximum compatibility with a light emitting diode (LED) lighting source.
