Abstract
A submount for red, green, and blue LEDs is described where the submount has thermally isolated trenches and/or holes in the submount so that the high heat generated by the green/blue AlInGaN LEDs is not conducted to the red AlInGaP LEDs. The submount contains conductors to interconnect the LEDs in a variety of configurations. In one embodiment, the AlInGaP LEDs are recessed in the submount so all LEDs have the same light exit plane. The submount may be used for LEDs generating other colors, such as yellow, amber, orange, and cyan.
