Abstract:
Sideways emission enhancements are described for light emitting diode (LED) lighting solutions having a wide variety of applications. While a typical LED lighting device has a substantial portion of its light emitted near a normal to the semiconductor photonic chip emitting the light, the present approach may suitable provide a compact, easily manufacturable device with good thermal design characteristics and a changed emission pattern without changing the horizontal mounting plane of the semiconductor photonic chip.
