Description

A waterproof laser light source heat dissipation inspection device

Technical field

The utility model relates to the field of stage lighting, in particular to a waterproof laser light source heat dissipation inspection device.

Background technique

Laser light source is an electric light source that uses excited particles to emit light under the action of stimulated radiation. It is a coherent light source. Laser light sources, like LED light sources, are solid-state light sources. Because of their high brightness, low power consumption, long range, good directivity, and bright colors that are not easy to drift, they are used in stage performances and outdoor landscape lighting projects, especially in the recent single-stage lighting projects. White laser light sources mainly use fluorescent functional materials to convert monochromatic lasers into white light, which greatly reduces the cost of laser light sources. This type of light source is more suitable for outdoor use in the stage lighting industry and is used to replace long-distance beam lights and searchlights. However, this kind of laser light source is small in size, the temperature of the light source is relatively concentrated, and the lamp light source has high requirements on the heat dissipation of the light source during the conversion process of the white laser light source.

During the assembly process of the lamp, a heat dissipation component is usually assembled on the laser light source to form a radiator component, and then the radiator component is integrally installed into the lamp. Although heat dissipation components use various methods to dissipate heat, such as heat pipes, radiators, air cooling, coating with thermal conductive materials, etc., due to the influence of accessories accuracy and assembly errors, the heat dissipation performance will inevitably be affected to a certain extent. As a result, the actual cooling effect of the radiator component is often not as good as expected.

Therefore, in actual production, after the radiator assembly including the light source is installed into the lamp, poor heat dissipation inside the lamp is often discovered only after the stage light is put into use as a whole. When this happens, the operator needs to disassemble the radiator assembly from the lamp bracket, make adjustments, and then reinstall it on the lamp. The disassembly and reinstallation of radiator components is relatively difficult and troublesome, consuming production manpower and time, and greatly affecting production efficiency; moreover, frequent assembly and disassembly can easily affect the waterproof performance of stage lights and easily lead to higher product defects. Rate.

The utility model discloses a waterproof laser light source heat dissipation inspection device, which is used to inspect the heat dissipation performance of a radiator assembly 10 containing a light source. The meaning of the radiator assembly 10 is: since the waterproof laser lamp has high requirements for the heat dissipation of the light source, for example, in this embodiment, the laser light source emits full power at a normal temperature of 25°C, and its temperature cannot exceed 55°C. Therefore, it is necessary to perform heat dissipation treatment on the laser light source plate 11 , and assemble a heat sink assembly 10 by installing various heat dissipation parts on the light source plate 11 . When assembling stage lighting, the radiator assembly 10 can be directly installed on the lighting bracket to complete the installation of the stage light source.
