US Patent 9523491 LED luminaire having lateral cooling fins and adaptive LED assembly

A luminaire including a housing made of thermally conductive material having a top, a bottom and two opposite sides connecting the top to the bottom, each side having plurality of external, vertically spaced, substantially parallel cooling fins that extend longitudinally and project laterally outwardly of the housing, preferably at a shallow downward and outward angle. The housing configuration provides a large surface area per unit of housing length to optimize heat dissipation. A configurable, cartridge-like LED bezel assembly—readily replaceable in the field—is supported on the bottom of the housing. A driver for the LED assembly—also readily replaceable in the field—is located within the housing.
