LIGHT-EMITTING DEVICES AND RELATED METHODS

摘要

Light-emitting devices and related methods are described that involve spatially distributing the light emission from a primary light source such as a laser or LED before it is incident on the photoluminescent material. The photoluminescent material emits a secondary emission that may comprise visible light. Some variations of the light-emitting devices may utilize an optical waveguide to couple-in light from the primary light source and spatially distribute the coupled-in light in a controlled manner to pump the photoluminescent material. A variety of configurations for high efficiency light fixtures may be possible using the light- emittins devices and methods described herein.
