Adjustable LED high-beam and low-beam module

Abstract

The invention relates to an adjustable LED high-beam and low-beam module. The adjustable LED high-beam and low-beam module comprises a low-beam module, a high-beam module and a linkage module, wherein the low-beam module comprises a low-beam support, independent widening component and light-dark cut-off line component which are connected to the low-beam support, a first bulb dimming mechanism and a second bulb dimming mechanism, the widening component is rotationally installed on a hinge seat of the low-beam support, and the second bulb dimming mechanism is installed on the back part of a first heat dissipater; the first bulb dimming mechanism and a third bulb dimming mechanism which are used for adjusting relative angles of the low-beam module and the high-beam module are installed at the two sides of the back part of the low-beam support; a third heat dissipater and a third reflector of the high-beam module are connected to a high-beam support, and a ball seat is installed on the high-beam support; and a linkage support of the linkage module is connected with a dimming motor, the ball seat and the third bulb dimming mechanism. The adjustable LED high-beam and low-beam module disclosed by the invention is compact in structure, and capable of realizing accurate adjustment for the relative positions of LED and the reflectors, and the relative positions of the high-beam module and the low-beam module, thus a production cost can be reduced.

Description

technical field [0001] The invention relates to an adjustable LED far and near light module, which belongs to the technical field of automobile lighting lamps. Background technique [0002] With the rapid development of the automotive industry, the importance of automotive lighting is increasingly reflected. After the car light source has experienced acetylene lamp - incandescent lamp - halogen lamp - xenon lamp, LED light source is widely used in the field of automotive lighting because of its high brightness, rich color variety, low energy consumption, long life and other advantages. [0003] However, the LED car light type is extremely sensitive to the positional error between its light source and the reflective surface, and its allowable deviation value should usually be controlled between 0.1 and 0.2 mm. Within the tolerance range, but during the assembly process, the cumulative tolerance of each component will inevitably lead to certain assembly errors, which will eve...

Problems solved by technology

In order to precisely control the light type of the low beam and the high beam, the current automobile headlights are equipped with dimming motors and ball head dimming mechanisms on the low beam module and the high beam module respectively, which not only causes the structure of the LED high and low beam module It is complex and requires high manufacturing precision, which increases the cost

Secondly, it is troublesome to operate the lock when adjusting the relative position of the LED light source and the reflector and the coincidence degree of the low beam light pattern and the high beam light pattern, and the production efficiency is low.
