  • High temperature resistant reflective layer for wavelength conversion devices
    Patent number: 11762190
    Abstract: A wavelength conversion device (100) comprises: a substrate (110), a reflective layer (120) on the substrate (110) and a wavelength conversion layer (130) on the reflective layer (120). The reflective layer (120) comprises a binder (121) and reflective titanium dioxide nanoparticles (122). The nanoparticles (122) have a particle size of about 200 nanometers to about 500 nanometers. The reflective layer (120) has enhanced thermal stability. Methods of manufacture the wavelength conversion device are also disclosed.

  • HIGH TEMPERATURE RESISTANT BINDER
    Publication number: 20230279267
    Abstract: Disclosed is an inorganic binder made with silica sol-gel, and a method of manufacturing the inorganic binder. Techniques and systems are disclosed for using the inorganic binder in light conversion systems, including phosphor wheels. Phosphor wheels with the inorganic binder are capable of withstanding high temperatures, have a highlight transmittance, have a high tensile-shear strength, can be applied by a flexible coating process, and have a low curing temperatures.
