摘要: In a light emitting package (8), at least one light emitting chip (12, 14, 16, 18) is supported by a board (10). A light transmissive encapsulant (30) is disposed over the at least one light emitting chip and over a footprint area (32) of the board. A light transmissive generally conformal shell (40) is disposed over the encapsulant and has an inner surface (44) spaced apart by an air gap (G) from, and generally conformal with, an outer surface (34) of the encapsulant. At least one phosphor (50) is disposed on or embedded in the conformal shell to output converted light responsive to irradiation by the at least one light emitting chip. A thermally conductive filler material disposed in the generally conformal shell (40) is effective to enhance a thermal conductivity of the composite shell material to a value higher than 0.3 W/(m.K).

摘要: Embodiments described herein provide optical systems that can mix colors to produce illumination patterns having a large area with uniform color. One embodiment of an optical system can include a set of optical units that each produces an illumination pattern with uniform color and intensity. The optical units are spaced so that the individual illumination patterns overlap to create an overall illumination pattern with an overlap area. In the overlap area, the colors emitted by the individual optical units mix to create a desired color. Embodiments of optical systems can provide beam control so that the optical units emit a high percentage of light in beam.
