[0024] Please refer to Figures 1-5 , the embodiments of the present utility model provide a technical solution: a point light source illumination module with a variable beam angle, including: a base 1, an installation housing 8 is provided at the middle position of the top of the base 1, an installation through hole 6 is jointly opened at the middle position of the bottom of the installation housing 8 and the middle position of the inside of the base 1, a heat dissipation component is arranged inside the installation through hole 6, a module 7 is installed at the inner bottom of the installation housing 8, a light source 13 matching with the module 7 is installed at the top of the module 7, and a beam angle adjustment component is arranged outside the installation housing 8.
[0025] The heat dissipation component includes a heat conduction plate 2, heat dissipation fins 3, a heat dissipation mounting plate 4 and heat conduction columns 5. The heat dissipation mounting plate 4 is installed at the middle position of the bottom of the base 1 and is sealed with the bottom of the installation through hole 6. Heat conduction columns 5 extending to the inside of the installation housing 8 through the installation through hole 6 are arranged on both sides of the top of the heat dissipation mounting plate 4. A heat conduction plate 2 fitting with the module 7 is jointly arranged at the top of the two groups of heat conduction columns 5, and heat dissipation fins 3 are evenly arranged at the bottom of the heat dissipation mounting plate 4.
[0026] The beam angle adjustment component includes a threaded rod 9, an internally threaded sleeve 10, a transparent glass 11, an adjustment convex lens 12 and a sealing housing 14. The sealing housing 14 is sleeved on the top of the outside of the installation housing 8. A transparent glass 11 is arranged at the middle position of the top of the sealing housing 14. An adjustment convex lens 12 matching with the light source 13 is installed at the inner top of the sealing housing 14. Internally threaded sleeves 10 are arranged on both sides of the sealing housing 14, and threaded rods 9 are threadedly penetrated through the two groups of internally threaded sleeves 10, and the threaded rods 9 are connected to both sides of the top of the base 1.
[0027] Bearings are arranged at the bottoms of the two groups of threaded rods 9, and the bearings are connected to the base 1.
[0028] Support plates are arranged on both sides of the bottom of the base 1, and internal threaded holes are opened on the sides far away from each other inside the two groups of support plates.
[0029] Fixing blocks are arranged on both sides of the inner top of the sealing housing 14, and fixing bolts matching with the adjustment convex lens 12 are penetrated through the fixing blocks.

[0032] Working principle: During use, the point light source illumination module can be installed at a specified position through an external fixing bolt. When it is necessary to adjust the beam angle between the adjusting convex lens 12 and the light source 13, the operator can directly rotate the threaded rod 9 to make it rotate inside the internal threaded sleeve 10, and then drive the internal threaded sleeve 10, the sealed housing 14 and the components above it to move to a specified position outside the base 1. By driving the movement of the sealed housing 14 through the internal threaded sleeve 10, the distance between the convex lens 12 and the light source 13 can be better adjusted. When the beam angle between 21 and the light source 13 is larger, the central light intensity is smaller and the light spot will be softer. On the contrary, when the beam angle is smaller, the central light intensity will be larger and the light spot will be harder.
[0033] When it is necessary to disassemble the sealed housing 14 and the mounting housing 8 later, the threaded rod 9 can be continuously rotated to remove the internal threaded sleeve 10 to the outside of it.
[0034] At the same time, when the point light source illumination module is working, the heat generated inside due to the operation of the module 7 and the light source 13 can be adsorbed by the mounting through-port 6 and the heat conducting columns 5. Finally, with the heat dissipation functions of the heat dissipation mounting plate 4 and the heat dissipation fins 3, the internal cooling efficiency can be effectively improved, the problem of partial circuit aging caused by high temperature can be reduced, and thus the service life of the point light source illumination module can be extended.

However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art to which the present invention pertains, various changes can be made without departing from the purpose of the present invention.
