Abstract

A wavelength conversion element comprises a substrate, a fluorescent powder layer and a through-hole blade. The substrate is configured to rotate based on an axis. The fluorescent powder layer is arranged on the substrate. The through-hole blade is disposed on the substrate, and has a pore density of between 10 ppi and 500 ppi, or has a volume porosity of between 5% and 95%.

Description

technical field [0001] The invention relates to a wavelength conversion element and a light source module Background technique [0002] In recent years, optical projectors have been used in many fields, and the range of applications is expanding day by day, from consumer products to high-tech equipment. Various optical projectors are also widely used in schools, homes and commercial occasions to amplify the display pattern provided by the signal source and display it on the projection screen. [0003] For the light source configuration of the optical projector, it can be driven by a solid-state laser light source to make the fluorescent material emit light. In this regard, the fluorescent material can be coated on the wheel, and the motor is used to drive the wheel to make it rotate at a high speed, so as to reduce the energy of the laser light source received by the fluorescent material in a unit time, thereby achieving the purpose of heat dissipation. However, as the bri...
