HIGH POWERED LIGHT EMITTER PACKAGES WITH COMPACT OPTICS

摘要

A light emitter includes a supporting surface, a light source positioned on the spreader region, and an encapsulant positioned on the spreader region to surround the light source. The encapsulant is capable of expanding and contracting along the surface of the spreader region in response to a change in temperature so that forces caused by differences in the coefficient of thermal expansion between the different components is minimized. One or more reflective elements can be positioned proximate to the light source to increase the light emitting efficiency of the light emitter. The reflective elements can include the a reflective layer on the spreader region and/or a reflective layer on a portion of the encapsulant.
