A light emitting assembly includes an elongated heat sink (22) of aluminum material, a heat spreader (24) of a copper material disposed on the heat sink (22), and light emitting diodes (26) disposed on the heat spreader (24). An insulating layer (54) is disposed on the heat spreader (24) and a circuit (62) including a ribbon (64) extends continuously along the insulating layer (54) between the light emitting diodes (26). A conformal coating (70) is disposed over the circuit (62) so that the heat sink (22), conformal coating (70), the ribbon (64), the insulating layer (54), and the heat spreader (24) are sandwiched together. A reflector (72) is disposed around each of the light emitting diodes (26) for reflecting the light in a predetermined direction. |
