WIPO Patent Application WO/2019/056208
Kind Code:
A1
Abstract:
A light conversion device comprising a layer formed from an inorganic binder, the inorganic binder comprising: from about 25 to about 80 wt％of a filler；from about 20 to about 75 wt％of an inorganic adhesive; and from about 0.5 to about 5 wt％of a dispersant. The inorganic binders are capable of withstanding high temperatures, have a high light transmittance, have a high tensile-shear strength, can be applied by a flexible coating process, and have a low curing temperature. Such inorganic binders could advantageously be employed in a variety of applications, such light tunnels (300), projection display systems, and optical light conversion devices, such as phosphor wheels (100), used in such systems.
