White light emitting device

摘要

The invention provides light emitting devices having a phosphor layer that are useful as sources of white light, and other applications. The invention provides a light emitting device having a laser diode and a phosphor composition positioned to receive light from the laser diode. The laser diode is adapted to emit light, and the phosphor composition is adapted to absorb light from the laser diode and emit light at longer wavelengths than the light from the laser diode.
