摘要： An illumination devices using excitation light and a wavelength conversion material to generated converted light for illumination, where the wavelength conversion material is excited by multiple excitation lights from both sides to achieve increased brightness. The excitation lights incident on the two sides of the wavelength conversion material may have the same color or different colors. Light separation structures are provided on both sides of the wavelength conversion material to separate the excitation light and the converted light. Light separation may be based on color difference or etendue difference of the excitation light and converted light. In one particular example, wavelength conversion material is formed on a surface of an LED which acts as the first excitation light source, and a second excitation light is delivered through a light separation structure onto the other side of the wavelength conversion material.

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.

The light emitting device (100) comprises a coherent source (110), a diffusing element (120), and a light guide part (140). The coherent source (110) is used for generating coherent light. The diffusing element (120) includes a first surface (121) and a second surface (122) which are opposite to each other, and the diffusing element (120) is used for dispersing the coherent light coming from the coherent source (110) so as to generate incoherent light.

The light guide part (140) is used for guiding the coherent light emitting from the coherent source (110) to be incident on the first surface (121) so as to form a first light path, guiding a part of incoherent light emitting from the first surface (121) to emit through the first light path, guiding the remaining incoherent light to emit through a second path, and separating the first path and the second path. The luminous flux of the incoherent light emitting through the first light path is less than that of the incoherent light emitting through the second light path.

摘要： A light source device includes a LED light source or a wavelength conversion material having a near Lambertian light emitting surface. The light source device includes a light recycling system to reflect small-angle lights (lights closer to the normal direction of the light emitting surface) back to the light source, and a collection system for collecting and outputting large-angle lights (lights farther away from the normal direction). The lights reflected by the light recycling system is scattered by the emitting surface in all directions, where the large-angle scattered lights are collected by the light collection system and the small-angle scattered light is reflected by the light recycling system again. A second excitation light source without wavelength conversion material or a second light source with its own wavelength conversion material may be provided, and the second light is directed to the light emitting surface by appropriate optical components.

摘要： A light source system and a projection system, comprising a light source (30); a switching system (40,60) switching light emitted by the light source (30) into at least two light beams (»1, »2, »3, »4) having a preset proportion in the manner of time division or light intensity division; a color wheel assembly (50, 70) located in a transmission light path of each light beam of the at least two light beams (»1, »2, »3, »4), with the color wheel assembly (50, 70) generating light having different colors and a preset proportion under the irradiation of each light beam of the at least two light beams (»1, »2, »3, »4), and light of different colors being able to synthesize a projection image after being modulated by a light modulation system, wherein the switching system (40, 60) can adjust the proportion of the at least two light beams (»1, »2, »3, »4) according to the parameters of the projection image, so as to adjust the proportion of the light of different colors. Once an offset of a white balance occurs on the projection image, the proportion of light beams of different colors can be adjusted by adjusting the proportion of the switched light beams, so as to achieve the white balance again, so that it is not necessary to replace same with a new color wheel, thereby solving the problems of relatively high costs and relatively large usage difficulty of the projection system.

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.
