Embodiment 1
[0033] Such as Figure 4 As shown, a sliding zoom lens bracket includes a sliding bracket 1 and a fixed bracket 2 that are mated and connected to each other. The sliding bracket 1 can slide up and down along the fixed bracket 2 .
[0034] Such as Figure 5 As shown, the sliding bracket 1 is a ring structure, including a main ring body 11, the upper part of the main ring body 11 is provided with an upper buckle 12, and the inner wall of the main ring body 11 is provided with a step 14, the upper buckle 12 and the step 14 It is used to fix the lens 4.
[0035] The lower part of the main ring body 11 is provided with a lower buckle 13, the lower buckle 13 is a PC plastic part, an ABS plastic part, a nylon part or an aluminum part, and the thickness of the lower buckle 13 is 0.5mm-1.5mm, preferably about 1mm. The lower buckle 13 has a certain degree of elasticity, thereby reducing the requirements for the processing technology of the bracket.
[0036] The outer wall of the main...
Embodiment 2
[0043]A lamp structure, including a sliding zoom lens bracket according to Embodiment 1. The sliding bracket 1 is fixedly connected with a lens 4 , and the fixed bracket 2 is fixedly connected with an LED light source 5 . Specifically, such as figure 1 , image 3 As shown, in this embodiment, the lens 4 is a TIR lens, the lens 4 is fixed on the sliding bracket 1 through the upper buckle 12 and the step 14, the LED light source 5 is installed on the light source bracket 3, and the light source bracket 3 and the fixed bracket 2 are fixed through the buckle 26 Connect with the positioning post 27 turnbuckles.
Embodiment 3
[0045] The difference between this embodiment and embodiment 2 is that, as figure 2 As shown, in this embodiment, the lens 4 is a convex lens.
