Illumination device

Abstract

The present invention is applicable to a lighting device and discloses a lighting device comprising a light source assembly, a housing assembly and an optical prism, the light source assembly is fixed in the housing assembly, and a light exit window is opened on the housing assembly. The optical prism is fixed in the light exit window, a sealing member is provided between the optical prism and the light exit window, and at least one convex rib is protruded on the side of the sealing member that is in contact with the optical prism. The lighting device provided by the present invention, by protruding ribs on the side wall of the sealing member, uses the compression deformation of the sealing member and ribs to seal the product, which improves the sealing performance and anti-vibration performance of the product. The glue seals the product, which is convenient for disassembly, assembly and maintenance, and avoids the technical problem in the prior art that the sealant is easy to drip onto the surface of the optical prism, causing the optical prism to be scrapped, thereby reducing the scrapping rate of the product.

Description

technical field [0001] The invention belongs to the field of lighting devices, in particular to a lighting device with good sealing reliability. Background technique [0002] In the prior art, the prisms in the lamps are all sealed with sealant on the four sides of the prisms before assembly, and then the prisms are assembled on the housing. After the sealant is cured, the sealing between the prisms and the housing of the lamps can be realized. However, when the lamps When it needs to be repaired or maintained and disassembled, it is necessary to clean up the residual sealant on the shell of the lamp and the prism. When assembling, it is necessary to apply sealant between the prism and the shell. After putting the prism into the shell, it is necessary to wait for the sealant to cure. This method of sealing between the prism and the lamp by applying sealant is time-consuming and laborious, which is not conducive to the maintenance and disassembly of the product, and it is ea...

Problems solved by technology

[0002]In the prior art, the prisms in the lamps are all sealed on the four sides of the prisms before assembly, and then the prisms are assembled on the shell, and the sealant is cured. The seal between the prism and the shell of the lamp can be realized, but when the lamp needs to be repaired, maintained and disassembled, the residual sealant on the shell of the lamp and the prism needs to be cleaned, and the sealant needs to be applied between the prism and the shell during assembly After putting the prism into the shell, you must wait for the sealant to cure before the lamp can be used. This method of sealing between the prism and the lamp by sealing the sealant is time-consuming and laborious, which is not conducive to product maintenance and disassembly, and is easy to seal. Glue dripped on the optical surface of the prism due to misuse, causing the prism to fail and be scrapped, resulting in inconvenient product maintenance and a high scrap rate; in addition, the sealant generally contains silicone grease and other ingredients, and the lamp will generate a high temperature environment when it is working. Silicone grease is easy to precipitate silicon powder in high temperature environment, and silicon powder is easy to adhere to the surface of the prism, which reduces the light extraction efficiency of the lamp
