Embodiment Construction

[0038] According to the present invention, in one way to be practiced here, in a translucent heat conducting element (for example, aluminum oxide (Al 2 o 3 ), transparent alumina (TPA), spinel, sapphire, etc.) to deposit conductive interconnects (transparent or reflective). This can be achieved by photolithography or, preferably, by screen printing. LEDs or LEDs on surface mountable ceramic substrates (also referred to herein as LED packages) are mounted (eg, by soldering or conductive adhesive) to interconnects on the translucent thermally conductive element. Preferably, the mounting method establishes a low thermal resistance contact from the LED to the light transmitting thermally conductive element. Light emitted by the LED is directed to the thermally conductive translucent element, where it passes through the thermally conductive translucent element and out through the thermally conductive light transmission (thereby emitting light, emitting light) element. The light ...

Abstract

A solid state light source having an LED in thermal contact with a thermally conductive translucent element, wherein light emitted from the LED is directed to exit a heat dissipating surface of the element. A thermally conductive translucent element is arranged or combined with a reflector to form a light recycling cavity. The outer surface of the thermally conductive translucent element forming the cavity becomes glow. At the same time, heat from the LEDs is conducted through and to the light-emitting outer surface of the cavity's elements, which radiatively and convectively cools the light source, eliminating the need for bulky additional heat sinks.
