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.

Abstract: Disclosed are a wavelength conversion device, and a light source system and a projection system therefor. The wavelength conversion device comprises a supporting structure and a plurality of wavelength conversion modules arranged together, each wavelength conversion module comprising a ceramic carrier and a phosphor material provided thereon. The supporting structure ensures that the plurality of wavelength conversion modules 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 phosphor material enables high temperature resistance, and prevents detachment of the phosphor material due to deformation at high temperatures. In addition, such a modular wavelength conversion device does not crack easily, and has a flexible design and shorter production cycle.

Abstract: A wavelength converter is provided. The wavelength converter comprises a light emitting-reflecting layer, and the light emitting-reflecting layer comprises a wavelength converting material, aluminum oxide, titanium oxide and an adhesive, which not only reduces the heat generated by the light propagation in the light emitting-reflecting layer, but also improves the density and heat dissipation performance of the wavelength converter. Thus, the wavelength converter is more applicable to a high-power excitation light source. A fluorescent color wheel and a light-emitting device comprising the wavelength converter are also provided.

Abstract: An illumination device includes a wavelength conversion material layer with a first surface, which includes a wavelength conversion material and a scattering material; a light guide device located adjacent the wavelength conversion material layer on a side facing its first surface for directing an excitation light onto the first surface of the wavelength conversion material layer, and for directing a mixed light emitted from the first surface, which includes converted light and remaining excitation light not absorbed by the wavelength conversion material layer, into a light exit port. In this illumination device, the light guide device can collect the excitation light reflected by the wavelength conversion material layer effectively, which insures that adding scattering materials into the wavelength conversion material layer doesn't have a significant impact on the luminous efficiency of the illumination device, and resolves the conflict between color uniformity and luminous efficiency of the device.
