[0002] With the gradual development of LED lighting fixtures, LED lamps are becoming more and more popular. Due to the advantages of high luminous purity, concentrated light beam, low power consumption and long service life, LED lighting fixtures have gradually replaced some traditional light source products in public places such as auxiliary lighting of lighting projects, and have played their highly controllable characteristics. From homes to office buildings, from roads to tunnels, from cars to pedestrians, from auxiliary lighting to main lighting, their scope of use is becoming wider and wider. The LED lighting fixture system with intelligent control has brought a higher level of service to mankind.

This production and fixing method consumes a lot of working time, and the silicone cannot move while waiting for it to solidify, which affects the subsequent production efficiency. In addition, the longer the silicone is outdoors, the less sticky it will be and the lower its shock resistance will be, which will cause the LED lens to fall off and affect its use.

The two groups of sleeves are provided with a limit rod extending into the limit groove on the side close to each other. The two groups of sleeves are provided with a spring connected to the limit rod on the side away from each other, so as to improve the convenience and flexibility of the lens snap-fitting and fixing.

[0007] According to the snap-on structure of the glue-applied lens, through grooves are provided on the tops of the two groups of sleeves, and a pulling block connected to the limiting rod is penetrated on the adjacent side of the two groups of through grooves, so that the later operator can pull the limiting rod to facilitate the release of the fixation.

[0008] According to the snap-on structure of the glue-coated lens, the sides of the two groups of the bottom of the clamping plates that are away from each other and the sides of the two groups of the top of the limiting rods that are close to each other are both provided with guiding inclined surfaces, and the two groups of guiding inclined surfaces cooperate with each other, so that the limiting rods can be pushed to move through the guiding inclined surfaces during the downward movement of the clamping plates, so as to facilitate the subsequent clamping and fixing work.

[0009] According to the snap-on structure of the glue-coated lens, internal threaded holes are provided at the middle positions on both sides of the substrate, and the two groups of internal threaded holes cooperate with external bolts to facilitate the later fixation and installation of the substrate and its components.
