Light-emitting diode-based white light sources are penetrating into the lighting market thanks to its energy efficiency. However, the brightness of such light source is limited by the droop effect, triggering exploration in the laser-driven white lighting because lasers have even higher efficiency without droop effect in addition to the compact size and small spot size. In this project, a new type of wavelength conversion material i.e. fluorescent silicon carbide (f-SiC) is explored as a laser-driven white light source, aiming to provide a better solution than the commercial phosphor solution in terms of brightness, thermal conductivity, and lifetime.
