Abstract:
An laser driven light source comprises a bulb that encloses a discharge medium, a laser beam unit for emitting a laser beam, wherein the laser beam is focused in the bulb for generating a discharge, and a beam shield element that is provided in the bulb to shield peripheral devices from the laser beam, which passes through the discharge generated in the bulb.
