Patent ID: 6902291

Claim:
An in-pavement high intensity LED-based luminaire comprising: a housing including a generally flat top surface having at least one transparent window for output light passage; a power controller having an input and an output, wherein the input is electrically connected to an airfield power infrastructure and the output is electrically connected to a light module; the light module including, a plurality of high flux LEDs, wherein each of the LEDs is connected to the power controller and emits light with a wide divergence, said LEDs located linearly in a plane perpendicular to an LED optical axis; a non-imaging light transformer that includes an input end opposite an output end, a refractive member located around the LED optical axis, and a total internal reflection member, wherein the light transformer collects a significant amount of light through the input end that is emitted by the LEDs that are located at a distance equal to the light transformer's focal distance from the input end, compresses and redistributes the collected light in a vertical plane with high efficiency into a predetermined pattern, and directs the compressed light outside of the light module through the output end; and a thermoelectric cooling device providing LED temperature control for emitted luminous flux, color and spatial intensity distribution stabilization, wherein the thermoelectric device is electrically connected to the power controller.
