[0023] See also Figure 1 and Figure 2 As shown, this embodiment provides a spatial light source homogenization system based on a semiconductor module, which includes: a laser generating mechanism 100; a homogenizing mechanism 200, wherein the homogenizing mechanism 200 includes a lens group 210, wherein the lens group 210 includes a homogenizing shaping lens 212 and a collimating beam expander lens 213, and a transmission channel 211 is provided inside the lens group 210, wherein the homogenizing shaping lens 212 and the collimating beam expander lens 213 are sequentially arranged at both ends of the transmission channel 211 on the laser transmission path, wherein the homogenizing shaping lens 212 is an aspherical optical lens, and the collimating beam expander lens 213 is a spherical optical lens.

[0024] The semiconductor module-based spatial light source homogenization system described in the utility model transmits the preliminarily homogenized light to the homogenization mechanism 200 through the laser generating mechanism 100. The homogenization mechanism 200 homogenizes and shapes the light through the homogenization shaping lens 212 arranged inside it, and then collimates and expands the homogenized light again through the collimating and expanding lens 213, and adjusts the angle, thereby making the output light more uniform and having a better processing effect. At the same time, it effectively avoids the process of mechanical coupling in batches during the operation stage of this system, and solves the problem that multiple light sources cannot be quickly connected. Compared with the existing conventional light source output technology, this application has the advantages of high light homogenization, wide application range, and good matching.

[0025] See also Figure 1As shown, in the process of outputting the spatial light source of the semiconductor module, if the homogenization effect of the output light source is not high, it means that the light is unevenly distributed during the emission process, which may cause uneven illumination on the surface of the object, affecting the visual effect and measurement accuracy, and may also cause uneven temperature distribution inside the module, affecting the performance and life of the module. Therefore, the laser generating mechanism 100 in this embodiment is used to output light after power is turned on, and it includes a laser light source 110 and a transmission optical fiber 120, the input end of the transmission optical fiber 120 is connected to the pump end of the laser light source 110, and the output end of the transmission optical fiber 120 is connected to the input end of the transmission channel 211, wherein the pump end is responsible for transferring energy to the fluid, so that it increases pressure and flows, and the first homogenization process of the present application can be realized in the above process. Specifically, the laser light source 110 in this embodiment is preferably a semiconductor laser module with a wavelength of 980nm, which can realize the conversion of a highly concentrated laser beam into a light with a more uniform light intensity distribution to meet different application requirements. In other embodiments, the laser light source 110 can also be adaptively adjusted according to actual use requirements, and the utility model does not make specific restrictions on this.

Specifically, the main body 221 in this embodiment is preferably a cylindrical barrel element, whose extension direction is the same as that of the lens group 210, and the lens group 210 is arranged at the center of the housing 220, and the light enters the housing 220 from the laser generating mechanism 100 and passes through the housing 220 from the other side of its length direction. In the extension direction of the shell 220, the connector 223 is arranged from the edge of the main body 221 toward its center and gradually approaches the laser generating mechanism 100. Specifically, the connector 223 is an SMA (Sub-Miniature Version A) connector 223 that can maintain excellent signal transmission performance, low loss, and low reflectivity. At the same time, it is easy to manufacture and install in automated equipment. Furthermore, the shell 220 in this embodiment also includes a connecting portion 222, which extends outward from the surface of the main body 221 to an external fixed surface. In actual use, the operator can connect the homogenizing mechanism 200 to the fixed surface through the connecting portion 222 by means of screws, bolts and other components, thereby improving the stability of the light output. See Figure 2 As shown, the housing 220 further includes a seal 224, which is disposed at the junction of the joint 223 and the laser generating structure to prevent moisture, dust and other pollutants from entering the homogenizing mechanism 200, and its base material is preferably elastic rubber.

It is an aspherical convex lens. When the light passes through the homogenizing and shaping lens 212, it can achieve homogenization and shaping under its refraction. Correspondingly, the collimating and expanding lens 213 is fixed inside the housing 220 and is arranged on the side of the transmission channel 211 away from the laser generating mechanism 100. It is a spherical convex lens. The operator can adjust the angle of the output light by adjusting the collimating and expanding lens 213, and achieve the effect of collimation and expansion. Specifically, in this embodiment, the lens group 210 also includes a lens pressure ring 214, which is arranged around the collimating and expanding lens 213 to fix the collimating and expanding lens 213.
