Detailed Description

The invention will be further described with reference to the following examples.

Referring to fig. 1 to 4, a lens includes a body 1, the body 1 is made of a transparent material, the body 1 includes a base 2 and a cover 3, the base 2 and the cover 3 are integrally formed, a light emitting cavity 4 for accommodating an external LED is recessed in the center of the base 2, a side wall of the base 2 protrudes out of an edge of the cover 3, the side wall of the base 2 is obliquely disposed, and a width of the base 2 gradually decreases from being close to the cover 3 to being far from the cover 3; the upper part of the cover body 3 is in a curved surface shape for light refraction and diffusion, and the end surface of the base 2 far away from the cover body 3 is provided with a matte treatment layer 7.

The utility model discloses simple structure can install in the TV for the TV is thinner, plays the effect that enlarges the light angle. An external LED is used as a light source to be arranged in the light-emitting cavity 4, and light emitted by the LED enters the body 1 to be refracted and reflected for adjustment. The upper part of the cover body 3 is in a curved surface shape for light refraction and diffusion, so that light waste is reduced, and the light utilization rate is improved. Through setting up base 2 to and the edge that the lateral wall of base 2 stretches out the cover body 3 suddenly, the lateral wall slope of base 2 sets up, and the width of base 2 reduces from being close to the cover body 3 to keeping away from the cover body 3 gradually. The structural arrangement can reduce the occurrence of difficult demoulding and even top cracking during the production of the lens, and improve the yield of the lens. The matte treatment layer 7 is arranged to reduce light leakage at the edge. The base 2 is integrally formed with the cover 3, which improves the rigidity of the structure. Specifically, the transparent material includes, but is not limited to, transparent rubber such as vulcanized rubber.
