Embodiment Construction

[0034] See figure 1 , figure 1 It is a structural schematic diagram of an embodiment of the light source system of the present invention. Such as figure 1 As shown, the light source system of this embodiment includes: a blue LD light source group 11, a reflector group (not marked), a spectroscopic device 15, a fluorescent color wheel 17, a first drive device 18, a first reflector 20, a second reflector A mirror 26 , a light combining device 21 , a color filter wheel 22 , a second driving device 23 , a light collecting device 24 and a control device (not shown). Among them, the blue LD light source group 11 includes a plurality of blue LD111 distributed on the substrate, and the blue LD111 is used to emit blue light; the reflector group includes a plurality of reflectors 12, and each blue LD111 has a one-to-one correspondence The reflector 12, the reflector 12 is used to reflect the blue light emitted by the corresponding blue LD111 to the spectroscopic device 15, so the fun...

Abstract

The invention relates to a light source system comprising a blue LD light source group, a beam splitting device, a fluorescent color wheel, a first drive device, a beam combining device, a filter color wheel, and a second drive device. The beam splitting device is used for transmitting blue light and reflecting colored light newly generated by the fluorescent color wheel. The fluorescent color wheel comprises at least three regions which are distributed along the center axis of the fluorescent color wheel, do not overlap, and are shaped like a fan ring, wherein the at least three regions comprise a first region for transmitting blue light, a second region for converting the blue light into red light, and a third region for converting the blue light into green light. The first drive device is used for driving the fluorescent color wheel to rotate along the center axis of the fluorescent color wheel. The beam combining device is used for combining colored light emitted by the fluorescent color wheel. The filter color wheel is used for selecting colored light in a time-sharing manner. The second drive device is used for driving the filter color wheel to rotate along the center axis of the filter color wheel so as to make the fluorescent color wheel and the filter color wheel rotate synchronously. Through the above method, the light source system provided by the invention can improve the color saturation and color gamut of a light source so as to improve the display quality of a picture displayed through projection.

Description

technical field [0001] The invention relates to the technical field of illumination and display, in particular to a light source system. Background technique [0002] A single-chip DLP (Digital Light Processor) projector needs to provide three colors of red, green, and blue on one imaging device at the same time, and its imaging principle is to generate a full-color projection image through a high-speed rotating color wheel , the color wheel consists of red, green, and blue blocks. In the prior art, after the white light emitted by the light source passes through the rotating color wheel, the red, green and blue colors in the white light will be sequentially and alternately projected onto the surface of the DMD (Digtal Micromirror Device) chip. The reflection from the small mirror on the camera reaches the lens, and then the lens is projected to the screen to form an image. However, the service life of the bulb light source is limited, and it cannot meet the requirements o...
