AI Technical Summary

Problems solved by technology

The high beams of existing automotive headlight systems are mostly designed with halogen bulbs for reflection or LED plus reflector structures. Headlights with these structures often have mediocre lighting effects. In a dark environment, the front illumination range is only More than 300 meters, it may cause safety problems during driving

Embodiment 1

[0019] Such as figure 1 As shown, it is the transmissive laser LED composite high and low beam and auxiliary high beam module of this embodiment, including laser transmitter 1, LED lamp 2, lens 3, radiator 4, fan 5 and LED circuit board 6, LED lamp 2 Fixed on the LED circuit board 6 , the laser emitter 1 and the LED lamp 2 are arranged side by side, the lens 3 is erected on the radiator 4 , and the laser emitter 1 and the LED lamp 2 are located between the lens 3 and the radiator 4 .

[0020] The number of laser emitter 1 and LED lamp 2 is one, and the number of lenses 3 is two. Laser emitter 1 and LED lamp 2 each correspond to a lens 3, and laser emitter 1 and LED lamp 2 are respectively in and It corresponds to the main optical axis of the lens 3 .

[0021] The radiator 4 is a finned radiator, and the position corresponding to the position of the laser emitter 1 on the radiator 4 is divided into upper fins 41 and lower fins 42 . The fan 5 is located at the back of the radi...

Embodiment 2

[0026] In this embodiment, the difference from Embodiment 1 is that the number of laser emitters 1 and lenses 3 is different. In this embodiment, the number of laser emitters 1 is two, the number of LED lights 2 is one, and the number of LED lamps 2 is one. The lamp 2 is located between the two laser emitters 1 , the number of lenses 3 is three, and the positions of the lenses 3 correspond to the positions of the laser emitter 1 and the LED lamp 2 one by one.

[0027] It can be understood that the number of laser emitters 1 and LED lights 2 can also be changed in other ways. The number of laser emitters 1 can be more than two, and the number of LED lights 2 can be more than one. 1 interval distribution, which can all achieve the same effect as this case.

Abstract

The invention belongs to the technical field of vehicle lamps and specially relates to a transmission type laser LED composite high-low beam, and auxiliary high beam module. The module includes laseremitters, LED lamps, lenses, a radiator and a fan. The laser emitters and the LED lamps are disposed side by side; the lenses are disposed on the radiator in an erection manner; the laser emitters andthe LED lamps are located between the lenses and the radiator; the number of the laser emitters and the number of the LED lamps are at least one; each of the laser emitters and the LED lamps is corresponding to one lens; and the fan is connected to the radiator. The transmission type laser LED composite high-low beam, and auxiliary high beam module can achieve auxiliary high beams brighter than standard high beams, so that vehicle driving is safer and more reliable.

Description

technical field [0001] The invention belongs to the technical field of vehicle lamps, and in particular relates to a transmissive laser LED composite high and low beam and auxiliary high beam module. Background technique [0002] With the development of the automobile industry, automobiles have become the main means of transportation and transportation for people in modern society. Automobile headlights are lighting fixtures for road lighting and identification of obstacles ahead when automobiles are driving under severe weather conditions. Use when driving at night. With the continuous development of headlight technology, people are no longer satisfied with ordinary low beam and high beam systems, and need to develop higher brightness, high comfort and safer automotive headlights. The high beams of existing automotive headlight systems are mostly designed with halogen bulbs for reflection or LED plus reflector structures. Headlights with these structures often have mediocr...
