Abstract
Disclosed is a manufacturing method for a wavelength conversion device, comprising: preparing a plurality of wavelength conversion modules, each wavelength conversion module comprising a ceramic substrate, a reflecting layer and a fluorescent powder layer, said layers being stacked sequentially and formed into one piece; installing and fixing the plurality of wavelength conversion modules on one surface of a base substrate. By arranging different fluorescent powders respectively on the different wavelength conversion modules, a plurality of wavelength conversion modules 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.
