AI Technical Summary
In the existing LED headlight lens fixing method, the fixing ring structure will block the reflection and absorption surface of the lens and the light absorption surface, resulting in a decrease in the utilization and light transmittance of the lens.
The design of a bracket is adopted, which includes two connecting arms, a first connecting plate and a second connecting plate. These plates are connected by glue to fix the lens, canceling the fixing ring structure, thereby releasing the absorbing surface and reflecting surface under the lens.
By abolishing the fixing ring structure and fixing the lens by glue bonding, the utilization and light transmittance of the lens are improved and the light can be effectively released.

Principle of the utility model: the fixing ring structure is eliminated, and the lens is fixed by gluing the first connecting plate and the second connecting plate, the absorption surface and the reflection surface below the lens are not blocked, and the light can be released, thereby improving the utilization rate and light transmittance of the lens.
[0005] As an improvement, the first connecting plate abuts against the incident surface of the lens.
[0006] As an improvement, the two connecting arms are arranged symmetrically on the left and right.
[0007] As an improvement, the positioning protrusion is arranged on the first connecting plate, and the positioning groove is arranged on the outer edge of the lens.
[0008] As an improvement, a plurality of first glue grooves are provided on the bottom surface of the first connecting plate, and a plurality of second glue grooves are provided on the top surface of the second connecting plate, and the first glue grooves and the second glue grooves are staggered in distribution.
[0009] As an improvement, the first connecting plate and the connecting arm are integrally formed, and the second connecting plate and the lens are integrally formed.
[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] The fixing ring structure is eliminated, and the lens is fixed by gluing the first connecting plate and the second connecting plate. The absorption surface and the reflection surface below the lens are not blocked, and light can be released, thereby improving the utilization rate and light transmittance of the lens.
