[0003] In traditional light source technology, the collimation of light is usually carried out by single lens structure.

[0031] Condensing assembly includes first straightening lens 9, and the side wall of first straightening lens 9 is fixedly connected in the side wall of compression ring 10, and the side wall of first straightening lens 9 is fixedly connected with focusing gasket 15, and the side wall of focusing gasket 15 is fixedly connected with second straightening lens 14, and first straightening lens 9 and second straightening lens 14 can adopt quartz glass material quality.Quartz glass has very low thermal expansion coefficient and high optical uniformity, can maintain good optical performance under the condition of high-power aluminum base lamp plate 12 heating and environmental temperature change, and the outer wall of second straightening lens 14 is fixedly connected in the inside of lens barrel 8, and the inner wall of lens barrel 8 is fixedly connected with high-power aluminum base lamp plate 12, and high-power aluminum base lamp plate 12 usually adopts aluminum as substrate, because aluminum has good heat conduction performance, can quickly conduct heat generated by lamp bead out.And lamp bead can select high-brightness LED chip or other suitable luminescent material, and the side wall of high-power aluminum base lamp plate 12 is fixedly connected with heat sink 11, and heat sink 11 can adopt copper or aluminum alloy heat dissipation fin structure, and is combined with heat pipe technology.Copper has excellent heat conduction performance, can quickly absorb the heat of high-power aluminum base lamp plate 12 and transfer to heat dissipation fin, and the outer wall of heat sink 11 is fixedly connected with power connection 13, and installation side plate 4 is provided with support assembly inside;

[0032] Specifically, in the process of using a high-parallelism coaxial light source, the core light-emitting component, a high-power aluminum-based light plate 12, plays a key role. When the power is turned on, the light plate is stably powered by the power connection 13, prompting the light plate to efficiently generate light. After the light is generated, it immediately enters the precise optical channel inside the lens barrel 8. Here, the light first encounters the second collimating lens 14, which, thanks to its unique optical curved surface design, preliminarily corrects and guides the propagation direction of the light, accurately transmitting it to the collection surface of the first collimating lens 9. At this time, the first collimating lens 9 works in coordination with the second collimating lens 14 to make fine adjustments to the light in multiple dimensions. The double-lens configuration can greatly improve the accuracy and stability of the light parallelism, effectively reducing the divergence and deviation of the light. The collimated light continues to travel and reaches the beam splitter 6. The beam splitter 6, based on its special optical coating and refraction principle, can intelligently identify and separate different wavelength components in the light, skillfully dispersing those unnecessary light sources that do not meet specific requirements, ensuring that only light of a specific wavelength range and propagation direction can pass through the subsequent optical path. Finally, the processed light, with the help of the optical amplification and focusing action of the anti-reflection lens 7, is transmitted to the designated location according to the preset path and intensity requirements, providing reliable light source support for various application scenarios that require high-parallelism light.

[0033] With reference to Figure 1 and Figure 3 , the support assembly includes a connecting ring 22 fixedly connected at the bottom to the top of the installation side plate 4 and slidably connected at the outer wall to the inside of the face plate 1. A sleeve ring 17 is slidably connected inside the connecting ring 22, and the sleeve ring 17 is suitably made of metal, such as aluminum alloy. Aluminum alloy has the characteristics of light weight and good wear resistance. A push rod 16 is slidably connected to the inner wall of the sleeve ring 17, and the push rod 16 can be made of stainless steel. The high hardness and good corrosion resistance of stainless steel enable it to maintain shape stability during frequent push-pull operations. A beveled column 21 is fixedly connected at one end of the push rod 16, and a clamping ball 20 is provided on the outer wall of the beveled column 21. The clamping ball 20 can be made of high-hardness alloy steel, which has good wear resistance and mechanical strength to ensure shape and performance stability during frequent sliding and clamping with the sleeve ring 17. The clamping ball 20 is slidably connected to the inside of the sleeve ring 17. A fixed ring 19 is fixedly connected to the bottom of the push rod 16. The beveled column 21 and the fixed ring 19 can also be made of metal, such as carbon steel. Carbon steel has high strength and hardness after appropriate heat treatment, which can meet the mechanical requirements of the beveled column 21 during the pushing of the clamping ball 20. A spring 18 is provided at the top of the fixed ring 19, with one end fixedly connected to the top of the fixed ring 19 and the other end fixedly connected to the outer wall of the push rod 16. The beveled column 21 is slidably connected to the inside of the sleeve ring 17, and the fixed ring 19 is slidably connected to the inside of the sleeve ring 17.

[0034] Specifically, when operating the structure of the mounting side plate 4 and the panel 1, etc., its unique dismounting and mounting mechanism exhibits the characteristics of convenience and efficiency. When dismounting is needed, firstly pull the push rod 16, and at the moment when the external force is applied, the push rod 16 will transmit the force to the spring 18 on the outer wall, causing the spring 18 to shrink. At the same time, with the displacement of the push rod 16, the inclined column 21 closely connected to the bottom of the push rod 16 will also move synchronously under the action of mechanical linkage. The movement trajectory of the inclined column 21 is designed very cleverly, and during its movement, it will accurately act on the clamping ball 20 on the outer wall, pushing the clamping ball 20 to move along a specific path until the clamping ball 20 completely enters the inside of the sleeve ring 17. At this time, the sleeve ring 17 is no longer restricted by the clamping ball 20 and can be easily pulled out, thereby quickly realizing the dismounting of the structure of the mounting side plate 4 and the panel 1, etc., greatly improving the convenience and efficiency of operation. When mounting, the whole process is the reverse process of dismounting. Under the action of the strong elastic force of the spring 18 itself, the spring 18 will quickly recover to the original stretched state, and in this process, the spring 18 will apply a reverse thrust to the push rod 16, prompting the push rod 16 to return to the inside of the sleeve ring 17 along the original path. With the homing of the push rod 16, the inclined column 21 connected thereto will also return to the initial position, and at this time, the clamping ball 20 on the outer wall of the inclined column 21 will be pushed out of the inside of the sleeve ring 17 with the help of the elastic force of the spring 18 and the pushing of the inclined column 21, and will return to the position where it can effectively lock the sleeve ring 17, ensuring that the structure of the mounting side plate 4 and the panel 1, etc. is stable and reliable after mounting, guaranteeing the structural integrity and stability of the whole device.

[0035] Working principle: When using a high-parallelism coaxial light source, first of all, the high-power aluminum-based lamp panel 12 is used to generate light, and generates light after being electrified. The power wiring 13 provides power for the lamp panel to enable it to work normally and emit light, and then the light source will move inside the lens barrel 8, and at the same time, the light source first contacts the second collimating lens 14, and then the second collimating lens 14 transmits the light source to the collection surface of the first collimating lens 9, and then the light source will be dispersed by the beam splitter 6, and the double-lens structure of the second collimating lens 14 and the first collimating lens 9 can more finely adjust the light propagation direction, improve the precision and stability of the light parallelism, and then the light source is transmitted to the designated position through the anti-reflection lens 7, and then when dismounting the structure of the mounting side plate 4 and the panel 1, etc., firstly pull the push rod 16, and the push rod 16 is stressed to drive the spring 18 on the outer wall to shrink, and then the push rod 16 moves and moves the inclined column 21 at the bottom, and then the inclined column 21 moves and drives the clamping ball 20 on the outer wall to move into the inside of the sleeve ring 17, and then the sleeve ring 17 can be pulled out, achieving the effect of quick dismounting. When mounting, directly through the elastic force of the spring 18, the push rod 16 is driven to make it return to the inside of the sleeve ring 17, and the clamping ball 20 on the outer wall of the inclined column 21 is pushed out of the inside of the sleeve ring 17.

[0036] Finally, it should be noted that the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
