Title: LASER LED HYBRID LIGHT SOURCE FOR PROJECTION DISPLAY
Abstract:
The present invention is a light source for a projection display. The light sources has a heat sink; a phosphor composition provided on the heat sink, wherein the phosphor composition is a phosphor powder, a ceramic phosphor or a liquid phosphor; one or more lasers directed at the phosphor composition; an electronic circuit connected to the one or more lasers to regulate power output to the one or more lasers; and a power source connected to the electronic circuit, wherein when the one or more lasers are activated exciting the phosphor composition the light emitted from the phosphor composition is the light source for the projection display.
