LED optical module with self-adaptation function

Abstract

The invention discloses an LED optical module with a self-adaptation function. The LED optical module comprises a radiator, an LED circuit board, a reflection panel, an LED lamp bank, a collimating lens, a lens support and an ordinary lens, wherein the lens support is clamped and mounted on the outer sides of the ordinary lens and the collimating lens; the reflection panel is mounted on the collimating lens in the projection direction of the LED lamp bank; a projection space for LED lamp bank projection light is reserved in the reflection panel; the LED lamp bank is mounted on the LED circuitboard; and the LED circuit board is mounted on the radiator. The LED optical module has the beneficial effects that firstly, LEDs are lined up or distributed in multiple rows, no reflector and condenser are used, the size of a car lamp body is greatly reduced, and many convenient conditions are provided for modeling design of a whole lamp; and secondly, precision parts such as reflector and condensers with high machining precision requirements are not used, the structure of the whole lamp is optimized, assembling errors between different parts are reduced, and the whole lamp performance is improved.

Description

Technical field: [0001] The invention relates to the technical field of vehicle lamps, and more specifically relates to an LED optical module with an adaptive function. Background technique: [0002] Compared with halogen lamps and discharge lamps, LEDs have many advantages. With the rapid development of LED light source technology, the traditional halogen and discharge high beams on the market will gradually be replaced by LED high beams. Due to the high color temperature of the LED and the high brightness of the high beam, the LED high beam is often more harmful to the eyes of pedestrians and drivers on the road. The high beam causes dazzling eyes of oncoming drivers and is one of the main causes of night traffic accidents. . So the high beam with ADB (adaptive driving beam) function came into being. The ADB function is mainly realized by controlling the on and off of LEDs through cameras, sensors, and control modules, and the LEDs are basically arranged in a matrix. At...

Problems solved by technology

[0003] (1) In terms of shape design: reflective type, because each group of LEDs will have a reflector, it will inevitably lead to an increase in the volume of the lamp body, strictly restricting the shape of the whole lamp, and it is difficult to meet the needs of different customers;

[0004] (2) Competitiveness perspective: the processing precision of the concentrator is high, and multiple groups of concentrators are added together, which will easily lead to a large deviation between the actual product and the design state, resulting in a decline in the competitiveness of the product;

[0005] (3) In terms of cost: the cost of concentrators is high, and the use of a large number of concentrators will inevitably lead to an increase in product costs and will also reduce its competitiveness
