Integrated type LED vehicle lamp

Abstract

An integrated type LED vehicle lamp comprises a lens, a shell, a control circuit board and an LED light-emitting source installed on the control circuit board. The lens is divided into a lens head and a lens body with an annular flange as a boundary. The lens body comprises a front thick body part and a thin tail part. A plurality of limiting protrusions are arranged on the end face of the end, close to the tail part, of the front body part at intervals in the circumferential direction. The shell comprises a front frame, a middle shell and a back cover. A limiting wall is arranged on the inner wall of the back cover, and a plurality of limiting parts are arranged at the top end of the limiting wall. The control circuit board is fixed to the inner wall of the back cover. The front frame, the middle shell and the back cover are sequentially connected. A containing cavity is defined by the back cover and the middle shell jointly. The annular flange of the lens is clamped between the front frame and the middle shell. The lens body part extends into the containing cavity, and the end face of the tail part right faces the LED light-emitting source. The limiting protrusions of the front body part are correspondingly connected with the limiting parts of the limiting wall in a one-to-one and abutted mode. The integrated type LED vehicle lamp is high in integration degree and installing and positioning precision and capable of fixing the lens well.

Description

technical field [0001] The invention relates to a car lamp, in particular to an LED car lamp. Background technique [0002] The integrated LED car light can integrate the LED light source, control circuit board, lens, and installation shell into one body to realize the modularization and structure simplification of the car headlight. However, the number of parts used in the existing LED car lights is still relatively large, and the integration level is not high. Too many parts lead to an increase in the manufacturing process, and the assembly error of the product is accumulated and magnified due to the errors of multiple parts. The installation process is complicated. In addition, the existing integrated LED car lights do not solve the problem of fixing and protecting the lens well. The above factors will ultimately affect the output performance of LED lights. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an ...
