LIGHT SOURCE USING A PHOTOLUMINESCENT PLATE

摘要

A light source using a photoluminescent plate is disclosed. A point light source such as an LED sources light into a linear light guide, which in turn deflects light into a surface light guide, which creates a surface of light by light extraction. One or more photoluminescent plates are situated between the linear and surface light guides, converting wavelengths of some of the light. In an embodiment, the photoluminescent plates can move, changing the wavelength conversion effect.
