Embodiment Construction

[0012] The matrix type headlight optical device of the present invention will be further described in detail through specific embodiments below.

[0013] Such as figure 1 , figure 2 As shown, a matrix type headlight optical device includes the optical area of ​​the high beam light composed of 42 LEDs 1, a tapered square rod 2 and an imaging lens 3. The 42 LEDs 1 are arranged in a matrix and emit light individually. control, the optical arrangement of the 42 LEDs 1 and the tapered square rod 2 generates 42 rectangular light spots in the near field, and the imaging lens 3 images the 42 rectangular light spots generated in the near field to the distance to reach the projection angle of the high beam . It also includes auxiliary cameras, radar and other equipment used to detect the driving situation ahead.

[0014] The working principle of the present invention is: in this device, the first optical structure is tapered square rod 2, and its optical principle is total reflectio...

Abstract

The invention relates to a matrix type vehicle lamp optical device which comprises an optical area of a high beam composed of 42 LEDs, a conical square rod and an imaging lens, the 42 LEDs are controlled to emit light independently, 42 rectangular light spots are generated in a near field through optical arrangement of the 42 LEDs and the conical square rod, and the imaging lens images the 42 rectangular light spots generated in the near field to the distance. The projection angle of the high beam is achieved. A high beam light is divided into 42 lighting areas, and light of each area is controlled by a single LED. In the driving process, the auxiliary camera, the radar and other devices are used for detecting the driving condition in front, turning off the corresponding LEDs and controlling the distance light of the area, the anti-dazzling purpose is achieved, the driving safety is improved, and the driving comfort is also improved.

Description

【Technical field】 [0001] The invention relates to the technical field of optics, in particular to a matrix type headlight optical device. 【Background technique】 [0002] With the improvement of living standards, cars have entered thousands of households, and cars have become an important means of transportation in people's lives. People have higher and higher requirements for automobile headlights. [0003] In the prior art, frequent manual switching of the high beam and the low beam will cause the fatigue of the driver. The abuse of high beams will also cause drivers to be dazzled and increase the probability of traffic accidents. Whether it is from the safety or comfort of driving, the generation of adaptive automobile headlights is required. 【Content of invention】 [0004] In order to solve the above problems, the purpose of the present invention is to provide a matrix type headlight optical device that can control the high beam in this area according to the driving ...
