Problems solved by technology

[0002] In a projection system, light sources of various colors are usually used, the most basic ones are red, green, and blue three primary color light sources, which are converged and collimated through a complex optical path, and then color-mixed and light-mixed, and then the light spots are adjusted. Shaping and light uniformity to achieve the required spot shape for output, mainly including two types, namely, a typical three-color LED or a three-color laser projection system light source combined light and mixed light, a light uniform system and a typical laser projection system light source combined light mixed light, Uniform light system. At present, the above-mentioned two typical light combining systems, light mixing systems and uniform light shaping systems of the above-mentioned projection light sources are all composed of very complex optical systems. The requirements are also very high, and assembly and debugging are difficult. In order to solve the above technical problems, a new technical solution is needed

Embodiment 1

[0020] see figure 1 , the present invention provides a technical solution: a projection light source transmission and light mixing and uniform light system, including a light source and an optical fiber bundle, characterized in that: the light source is divided into a red light source 1, a green light source 2 and a blue light source 3, the The above-mentioned fiber bundles are divided into red light fiber bundles 4, green light fiber bundles 5 and blue light fiber bundles 6, and the red light fiber bundles 4, green light fiber bundles 5 and blue light fiber bundles 6 are uniformly aggregated to form a composite The optical fiber bundle 7, the optical fiber bundle 7 adopts random distribution, so that the light distribution at the exit port is uniform, the right output end of the combined optical fiber bundle 7 is the fiber exit end face 8, and the red light fiber bundle 4 , The left input ends of the green light fiber bundle 5 and the blue light fiber bundle 6 are provided wi...

Embodiment 2

[0023] see figure 2 , the principle of this embodiment is the same as that of Embodiment 1. When in use, the light emitted by the laser array 9 reaches the dichroic film 17 through the beam compression optical path 10, and the dichroic film 17 passes the red, green, and blue light rays through the converging lens 11 to reach Laser conversion system 12, the laser conversion system 12 reflects red light and green light through blue light, the transmitted blue light enters the blue laser coupling end face 14, and reaches the fiber output end 16 through the optical fiber bundle, the reflected red light and green light will be Enter the red-green light coupling end face 15 through the focusing lens 13, and reach the fiber exit end 16 through the fiber bundle. Good performance and high transmission efficiency. According to different chip specifications of the projection system, the end face can also be circular, elliptical or polygonal in shape.
