Abstract:
Lighting packages are described for light emitting diode (LED) lighting solutions having a wide variety of applications which seek to balance criteria such as heat dissipation, brightness, and color uniformity. The present approach includes a backing of thermally conductive material and two or more arrays of LEDs attached to a printed circuit board (PCB). The PCB is attached to the top surface of the backing and the two or more arrays of LEDs are separated by a selected distance to balance heat dissipation and color uniformity of the LEDs.
