[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0043] The high-power light source structure of the target optical simulation device needs to meet the following requirements at the same time: provide a light source that meets the requirements, the volume should be as small as possible, and the heat dissipation performance should be as good as possible. How to provide a light source structure that meets the above requirements is the problem to be solved by the present invention, which is further explained through the following examples.

[0044] like Figure 1 and Figure 2As shown, the high-power light source structure of the target optical simulation device provided in this embodiment includes a metal base 1, a metal heat dissipation structure 2, lamp beads 3 and a fan 4.

[0045] The metal base 1 comprises a support 11 and a barrel 12. The barrel 12 is connected to the support 11, enabling the support 11 to securely mount the simulation device. An optical lens 13 is located at the front end of the barrel 12, protecting the lamp and preventing dust. It also corrects focus shifts caused by the different refractive indices of infrared and visible light, providing preliminary correction for incoming light.

[0046] See also Figure 2 and Figure 3 As shown, the metal heat dissipation structure 2 includes a heat conducting section 21 and a heat dissipation section 22. The heat conducting section 21 is inserted into the rear end of the cylinder 12 and is close to the inner wall of the cylinder 12. The end is spaced apart from the optical lens 13 to form an installation space. The heat dissipation section 22 and the heat conducting section 21 are processed as one piece. The heat dissipation section 22 includes a plurality of heat dissipation fins 221 arranged at intervals to increase the heat dissipation area.

[0047] The lamp bead 3 is a high-power lamp bead, which is arranged in the installation space and installed at the end of the heat-conducting section 21 , and the light emitted is emitted after passing through the optical lens 13 .

[0048] The fan 4 is installed on the rear side of the heat dissipation section 22 and is spaced apart from the heat dissipation section 22 for dissipating heat from the heat dissipation section 22 .

[0049] During operation, light from the lamp beads is emitted through the optical lens, providing illumination for the simulation device. Heat generated by the lamp beads is transferred to the metal heat dissipation structure and dissipated through the heat dissipation section. The presence of a fan further accelerates heat dissipation efficiency. The entire light source has a simple structure and a small size, providing excellent heat dissipation and extending the light source's service life.

[0050] To ensure effective heat dissipation, structural strength, and ease of fabrication, the metal heat dissipation structure 2 is made of copper. In one example, the heat dissipation section 22 is square and 80 mm in size. The heat sink 21 is 1 mm thick, with a 2.5 mm spacing between adjacent heat sinks 21 and a depth (from the heat dissipation section to the heat conduction section) of 10 mm.

[0051] To further improve the heat dissipation effect, a plurality of heat dissipation slots 23 are arranged at intervals in the heat dissipation section. In one example, the plurality of heat dissipation slots 23 are arranged in parallel and at intervals, and the width of the heat dissipation slots 23 is 2.5 to 4 mm, for example, 2.5 mm, 3 mm, 3.2 mm, 4 mm, etc.

[0052] In order to facilitate processing and installation, in one example, see Figure 2As shown, the fan 4 is mounted on the heat dissipation section 22 via a mounting post 24 . The mounting post 24 is integrally formed with the heat dissipation section 22 . A threaded hole is provided at the end of the mounting post 24 for threaded engagement with a fixing screw of the fan 4 .

[0053] In a specific example, a 30W high-power lamp bead is used, and the metal heat dissipation structure 2 is made of copper. In one example, the heat dissipation section 22 is 80mm square, the thickness of the heat dissipation fin 21 is 1mm, the interval between two adjacent heat dissipation fins 21 is 2.5mm, the depth is 10mm, and five heat dissipation slots 23 are set (distributed as shown in FIG. Figure 3 As shown), the width of each heat dissipation groove 23 is 3.5 mm, which can keep the temperature of the lamp bead below 52 degrees during operation.

[0054] In one example, see Figure 1 and Figure 2 As shown, the support 11 and the cylinder 12 are processed as one piece.

[0055] In one example, see Figure 1 and Figure 2 As shown, a plurality of screw holes are provided on the circumference of the cylinder 12, and threaded connection holes that match the number and position of the screw holes are provided on the circumference of the heat conducting section 21. The heat conducting section 21 is fixed to the cylinder 12 by connecting the screws with the threaded connection holes. A light leakage-proof seal, such as a rubber gasket, is provided at the threaded connection hole to prevent stray light.

[0056] In order to facilitate the passage of wires and prevent stray light, in one example, a wire hole 121 is provided on the cylinder 12 for the passage of the lamp power line. A light leakage-proof seal is provided at the wire hole 121, such as a rubber ring with a wire hole, to prevent stray light and reduce interference while achieving wire passage.

[0057] In one example, see Figure 2 As shown, a retaining ring 122 is provided on the inner wall of the cylinder 12, one side of the optical lens 13 rests on the retaining ring 122, and a pressing ring 5 is provided on the other side to fix the optical lens 13 to the cylinder 12. Preferably, a sealing ring 6 is also provided at the optical lens 13, for example, the sealing ring 6 is provided between the pressing ring 5 and the optical lens 13 to seal and prevent light leakage and reduce interference.

[0058] To further prevent stray light, in one example, at least the interior of the cylinder 12 is blackened, and the entire metal heat dissipation structure 2 is blackened to prevent stray light from escaping and reduce interference. It should be noted that blackening the metal surface is a prior art and will not be described in detail here.

[0059] Any details not described in detail in the present invention are common knowledge or prior art in the art.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that not every embodiment contains only one independent technical solution. In the absence of a conflict of solutions, the various technical features mentioned in each embodiment can be combined in any manner to form other implementation methods that can be understood by those skilled in the art.

[0061] In addition, without departing from the scope of the present invention, the technical solutions described in the aforementioned embodiments may be modified, or some of the technical features thereof may be replaced by equivalents, without causing the essence of the corresponding technical solutions to depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
