Abstract
LED downlight and other point source luminaires contain one or more Application-Specific LED modules with integrated optical, mechanical, and heat dissipation systems; a fluted extruded metal housing acts as a heat sink as well as the luminaire housing containing the AS-LED module(s) or receiving a rotatable spherical housing that contains the AS-LED module, printed circuit board units, and wires; mounting brackets; and a remote LED driver. The extruded aluminum housing (and heat sink) may be comprised of a single cylinder or multiple concentric cylinders. The heat dissipation base of the AS-LED module can be any shape and size dependent on the type of LED luminaire the AS-LED module is designed for. The LED luminaires have a short thermal path, including just one electrical/thermal insulation layer between the LED chips and the housing, and one optical lens system between the LED chips and the surrounding ambient air.
