High beam and low beam integrated LED automobile lens

Abstract

The invention discloses a high beam and low beam integrated LED automobile lens. The problems that an existing automobile headlamp is short in service life, large in size, unclear in cut-off line and low in brightness are mainly solved. According to the high beam and low beam integrated LED automobile lens, a cooling fan (1) is mounted at the tail of a cooling support (2), and a low beam lamp bead (3) and a low beam reflecting cup (5) are arranged on the upper surface of the cooling support (2); and a high beam lamp bead (4) and a high beam reflecting cup (6) are arranged on the lower surface of the cooling support (2), a shading plate (7) and a lens support (8) are mounted at the front end of the cooling support (2), and the front end of the shading plate (7) is of a crescent sharp knife edge structure, and used for blocking out a straight bright-dark clear cut-off line. The shading plate (7) is sleeved with the lens support (8), a lens (9) is mounted at the front end of the lens support (8), and the lens (9) is used for refracting light to be in the light types of low beams and high beams. According to the structure, the LED automobile lens is clear in cut-off line and high in brightness.

Description

technical field [0001] The invention relates to the field of automobile lighting equipment, in particular to an LED automobile lens integrating far and near light. Background technique [0002] Light-emitting diodes (LEDs) are considered to be one of the most potential light sources at present because of their main characteristics such as small size, high luminous efficiency, long life, no flicker, and high brightness. In the existing automotive lighting applications, glass lamp beads with tungsten filaments as the wick are mainly used. The lamp beads are large in size, low in luminous efficiency, and short in life. Due to the large size of the lamp beads, the car headlights with tungsten lamps as the light source need a larger reflector cup, and the exposed lamp beads affect the appearance. In addition, car headlights have high beam and low beam functions. The low beam reduces the glare of oncoming vehicles, and the high beam illuminates a longer distance. Existing car he...

AI Technical Summary

Problems solved by technology

Existing car headlights are divided into far and near light separation structure and far and near light integrated structure, the volume of the far and near light integrated structure is relatively small, but its low beam is not bright enough, the cut-off line of light and dark is not clear enough, and the sense of dazzling is strong; The light is not concentrated enough, and the irradiation distance is short
