Problems solved by technology

Although the temperature resistance of the ceramic substrate can be greater than 600°C, it is not easy to form the aforementioned boss structure on the surface of the ceramic substrate, resulting in poor heat dissipation effect using the ceramic substrate, which in turn affects the excitation efficiency of the fluorescent wheel
In addition, the ceramic substrate itself is a brittle material, which is prone to hidden cracks during the molding and processing of the substrate, and cracks during operation, which will affect the reliability of the fluorescent wheel

Abstract

A wavelength conversion module comprises a ceramic substrate, a wavelength conversion layer and a plurality of colloid bosses. The ceramic substrate has a first surface. The wavelength conversion layer is disposed on the first surface of the ceramic substrate. The colloid bosses are separately arranged on the ceramic substrate and at least located on the first surface. The colloid boss and the wavelength conversion layer are separated from each other, and the heat resistance temperature of the colloid boss is greater than 500 DEG C. The wavelength conversion module has a good heat dissipation effect.

Description

technical field [0001] The present invention relates to an optical module and a projector, and more particularly, to a wavelength conversion module and a projector having the wavelength conversion module. Background technique [0002] Most of the existing fluorescent wheels use a metal substrate of aluminum or aluminum alloy as the heat dissipation substrate, and the external design of the heat dissipation substrate is mostly a plane circular or annular structure, and there is no special structure on its surface. In order to increase the efficiency of heat dissipation, at present, the surface area is increased by forming a boss or groove structure on the front, back or both sides of the heat dissipation substrate by stamping or processing. In the process of high-speed rotation of the fluorescent wheel, these boss structures will generate turbulence or enhance convection, and accelerate the removal of heat around the fluorescent wheel through these turbulence or convection, s...
