摘要： A light conversion device is disclosed. The light conversion device includes a substrate and a wavelength conversion element. The wavelength conversion element includes an inorganic binder, such as sodium silicate. Also disclosed are phosphor wheels and light engines including such phosphor wheels. Further disclosed are high-power laser projection display systems comprising a laser having a power of from about 60W and about 300W and a light conversion device. The use of an inorganic binder permits high thermal stability at reasonable cost.
