摘要

We have designed and fabricated angle-selective filters to increase the luminous throughput of a blue light emitting diode (LED) and its associated color wheel. The emission direction was tailored to increase the light emission in the useful direction by using multilayer optical coating with alternating high and low refractive indices layers. The angle selective filters limit the luminance angle to less than an acceptance angle of 30 degrees for green and red on the phosphors color wheel. The filters increase the luminance efficiency by converging and recycling the light. The color performance of the phosphors color wheel was improved and gave an advantage of energy saving in the LED projector.
