LED LIGHTING MODULES AND LUMINAIRES INCORPORATING SAME
First Claim
1. A light emitting diode (LED) lighting module for installation in a light fixture as a replacement for a lamp, said module, comprising:
- (a) a polyhedral body of highly thermally conductive material, said body having a mounting axis and a plurality of exterior facets disposed about said mounting axis in a substantially polygonal array, each of said facets facing outwardly away from said mounting axis and at a downward angle with respect to said mounting axis;
(b) a support having an upper end and a lower end, said upper end and said lower end being mutually spaced from one another along said mounting axis, said body being supportably mounted to said upper end of said support, said lower end of said support being adapted to be mechanically coupled to the light fixture;
(c) a plurality of LEDs, at least one LED of said plurality of LEDs being supportably mounted to each respective one of at least a majority of said facets and thermally conductively coupled to said body, each of said LEDs having an optical axis oriented at an acute angle with respect to said mounting axis, and(d) a plurality of heat dissipating fins supportably mounted to said body and thermally conductively coupled to said body.

Abstract
LED lighting modules have a highly thermally conductive polyhedral body having a plurality of exterior facets disposed around a mounting axis in a polygonal array facing outwardly away from the mounting axis and at a downward angle thereto. At least a majority of the facets carries at least one LED whose optical axis is angled acutely. The body carries a plurality of heat dissipating fins and serves as a heat sink to prevent overheating the LEDs in a transient and steady state operation. For retrofit applications, the module is mounted to a fixture via either a support or a bracket in a mounting position in which the elevation of the LEDs is determined according to the mounting and geometry of the replaced lamp.
