LED and thermal management module for a vehicle headlamp

An LED light source module comprising:

• an LED array light source on backing thermally coupled to a first cooling fin element;
• the first cooling fin element thermally coupled to the LED with the opposite side having an array of perpendicularly protruding cooling fin short legs with distal ends adjacent to a fan, protruding cooling fin leg array supported by a substantially thin flat base element;
• the thin flattened fan in a plane parallel to the first cooling fin base element, sandwiched between the first cooling fin element and a second cooling fin element, wherein the fan electrically coupled to a power source;
• the second cooling fin element juxtaposed and parallel to the first cooling fin element, comprising a flat base supporting an array of protruding cooling fin short legs with distal ends adjacent to the fan and base ends coupled to the thin base element in a plane parallel to the plane of the fan, the base element side opposite the leg array thermally coupled to an LED driver circuit board;
• the LED driver circuit board with electronic circuitry for supplying the LED light source with voltage and current of a predetermined waveform and magnitude to power the LED source in accordance with electrical requirements of the LED and electronics;
• an optical composite lens comprising a at least one partial aspheric lens configured with respect to the LED array light source beam centerline;
• whereby the LED light module contains a compactly structured LED light source with beam shaping composite lens for collimating and directing light onto a desired forward pattern, associated thermal management and control circuitry for minimizing the LED negative temperature coefficient character, all in one package.
