Description

Technical Field

[0001] The utility model relates to the technical field of coaxial light sources, in particular to a high-brightness air-cooled coaxial light source. Background Art

[0002] With the development of industrial automation, LED light sources are usually used in conjunction with smart cameras to complete the inspection of industrial products. Different light sources are selected according to the reflective characteristics of the object being inspected.

[0003] According to the structure of the light source, it can be divided into annular light sources, backlight sources, strip light sources, linear and coaxial light sources, etc. The structure of the light source is different, and its function is also different. According to the needs of the use environment, choose the light source with the corresponding structure. For example, the linear light source, its structure uses a cylindrical lens to focus light, has high-brightness light, and is used in AOI with an automatic camera; and the coaxial light source can provide more uniform light than the ordinary light source, which improves the accuracy and reproducibility of visual inspection, so it is widely used in the inspection of products with strong reflectivity. In the fields of high-speed inspection such as metal surface scratch detection, liquid crystal mark positioning, laser marking, and QR code recognition, high-brightness coaxial light sources are generally used. Because high-brightness LED lamp beads are used inside, their power and heat generation are relatively large compared to ordinary LED lamp beads. If the heat is not dissipated in time, it will not only reduce the service life of the light source equipment, but also increase the energy consumption of the light source; in order to avoid the above problems, the existing technology uses a cooling fan to cool the light source. However, the existing high-brightness air-cooled coaxial light source has uneven heat dissipation and cannot be used for a long time, which will affect the life of the light source equipment. For this reason, we propose a high-brightness air-cooled coaxial light source. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a high-brightness air-cooled coaxial light source.

[0005] The utility model is implemented by the following technical scheme: a high-brightness air-cooled coaxial light source, comprising an air-cooling structure, a heat dissipation structure and a lens structure, wherein the heat dissipation structure is located at the right end of the air-cooling structure, and the lens structure is located at the right end of the heat dissipation structure;

[0007] As a further improvement of the above solution, there are two air blowers, which are symmetrically distributed inside the air cooling chamber in the upper and lower parts.

[0008] Through the above technical solution, two blowers supply cold air to the entire device, thereby achieving a uniform heat dissipation effect.

[0009] As a further improvement of the above scheme, the heat dissipation structure includes a heat sink, a surface of the heat sink is provided with an air outlet, an outer wall of the air outlet is fixedly connected to an LED light board, and one side of the LED light board is fixedly connected to a light-emitting surface.

[0010] As a further improvement of the above solution, the air blower is arranged opposite to the air outlet, the LED light board is composed of a plurality of LED lights, and the heat sink is equal to the LED light board in size.

[0011] Through the above technical solution, the cold air generated by the blower is delivered through the air outlet, thereby cooling and dissipating the circuit inside the entire device, thereby extending the life of the light source equipment.
