Title:
Wavelength converter and its light source system, projection system
Document Type and Number:
Japanese Patent JP6353041
Kind Code:
B2
Abstract:
Disclosed are a wavelength conversion device, and a light source system and a projection system therefor. The wavelength conversion device comprises a supporting member (104) and a plurality of wavelength conversion modules (108a, 108b) arranged each relative to the others, each wavelength conversion module (108a, 108b) comprising a ceramic carrier (103) and a fluorescent powder (101) arranged thereon. The supporting member (104) ensures that the plurality of wavelength conversion modules (108a, 108b) remain fixed relative to one another. The light source system and the projection system both comprise the present wavelength conversion device. The use of ceramic material as the carrier for the fluorescent powder (101) enables high temperature resistance, and averts any failure of the fluorescent powder (101) to attach due to high-temperature deformation. In addition, using the method wherein a plurality of wavelength conversion modules (108a, 108b) are arranged each relative to the others produces a modular wavelength conversion device that is difficult to break, and has a flexible design and shorter production cycle.
