Description

Technical Field

[0001] The utility model relates to the technical field of supplementary lights, and more particularly to a coaxial light infrared supplementary light. Background Art

[0002] With the rapid development of modern monitoring technology, cameras have been widely used in many fields such as security, transportation, and industrial automation. However, in low-light or no-light environments, the imaging effect of traditional cameras is often limited by insufficient light, resulting in unclear images. To solve this problem, various types of supplementary lights have emerged on the market, including visible light and infrared supplementary lights. Infrared supplementary lights can enhance the imaging ability of cameras at night or in low-light conditions by emitting invisible infrared light, avoiding the interference of visible light supplementary lighting on the surrounding environment or monitoring targets.

[0003] The existing security camera supplementary lighting mainly uses infrared plus white light. The encapsulation of infrared plus white light supplementary light beads chips usually adopts a non-coaxial encapsulation method with upper and lower distribution, and a lens with a fixed angle is installed above the light beads. However, when the design requires the light beads to turn 90 degrees or other angles for patching, the light distribution curve of the light beads will change, and the imaging effect of the camera will have a large difference, which needs to be corrected by adjusting the direction of the lens. When there are multiple light beads with inconsistent directions on the light board, the production efficiency is seriously affected.

[0004] Therefore, a coaxial light infrared supplementary light is needed to solve the above problems. Summary of the Utility Model

The infrared chips are surrounded to form a circle, and its center coincides with the LED chip to form coaxiality between the first light source member 2 and the plurality of second light source members 3. During the assembly process, even when the plurality of second light source members 3 rotate, there is no need to adjust the direction of the lens 4 to correct the light distribution effect, thereby effectively improving the assembly efficiency of the supplementary light and saving the labor cost of assembly.

[0030] The material of the lens 4 can be optical glass or plastic, which has good light transmittance and weather resistance.
