摘要:
Disclosed is a manufacturing method for a wavelength conversion device, comprising: preparing a plurality of wavelength conversion modules (2a, 2b, 2c), each wavelength conversion module (2a, 2b, 2c) comprising a ceramic substrate (23), a reflecting layer (22) and a fluorescent powder layer (21), said layers being stacked sequentially and formed into one piece; installing and fixing the plurality of wavelength conversion modules (2a, 2b, 2c) on one surface of a base substrate. By arranging different fluorescent powders respectively on the different wavelength conversion modules (2a, 2b, 2c), a plurality of wavelength conversion modules (2a, 2b, 2c) can be produced separately at the same time, thereby significantly shortening the production cycle. Each such module is produced independently and is thus not subject to the restrictions of the characteristics of other fluorescent powders. This is beneficial for the optimization of the various processes, and a wavelength conversion device having optimal performance is thereby obtained.
摘要:
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.
