Beschreibung
Zusammenfassung:	A wavelength conversion device (100), such as a phosphor wheel, comprises: a substrate (110), a reflective layer (120) and a wavelength conversion layer(130) on the reflective layer (120). The reflective layer (120) comprises (A) an inorganic binder or an organic silicone, and (B) reflective nanoparticles (122). The nanoparticles (122) have a particle size of about 200 nanometers to about 500 nanometers. The reflective layer (120) has high thermal stability. A method of manufacturing the wavelength conversion device (100) and a light projection system comprising the wavelength conversion device (100) are also disclosed.
