Abstract:
A light assembly includes a light source circuit board and a plurality of light-emitting diodes disposed on the light source circuit board. A plurality of light pipes axially extends from and adjacent to each light-emitting diode. Each light pipe has a respective first end adjacent to the plurality of light-emitting diodes and a second end opposite to the light-emitting diodes. The plurality of light pipes communicates light from the light-emitting diodes therethrough and defines a cavity therebetween. A plurality of thermal vanes forms a heat sink for removing heat from the light-emitting diodes. The plurality of thermal vanes extend adjacent to the plurality of light pipes. A driver circuit board is disposed within the cavity.
