Abstract
A laser light assembly includes a substrate, a reflective phosphor plate, a plurality of laser diodes, a light shield, at least one mirror, a plurality of beam-shaping lenses, and a first lens. The reflective phosphor plate is coupled to the substrate and converts incident blue laser light into white light. The laser diodes emit the blue laser light. The light shield prevents the blue laser light emitted by the laser diodes from escaping the assembly. The mirror reflects the blue laser light emitted from each laser diode toward a predetermined position on the reflective phosphor plate, whereby the reflective phosphor plate emits white light. The beam-shaping lenses are disposed between a different one of the laser diodes and the mirror. The first lens receives the white emitted from the reflective phosphor plate.
