An LED light source far and near light integrated car light module

Abstract

An LED light source far and near light integrated car light module, the high beam LED circuit board (5) and the low beam LED circuit board (8) are respectively arranged behind the concentrator 1, and the reflector includes a primary reflector (10) and a low beam LED circuit board (8). The secondary reflector (9) is used to form the low beam light shape. The primary reflector (10) can independently form the broadening of the low-beam light shape, and the secondary reflector (9) increases the number of rays forming the low-beam light shape, and at the same time, part of the reflected light is used to form zone III of the low-beam light shape. The light emitted by the LED light source on the low-beam LED circuit board (8) is reflected by the first and second reflectors, and most of the light is refracted by the lens (4) and then emitted to form a low-beam light on the screen. The broadening (5-1) of the shape, another small part of the light is reflected and refracted by the condenser and then emitted from the lens (4), forming the cut-off line (5-2) and zone III of the low-beam light shape (5‑3). According to the invention, there is no need to make a square aluminum-plated surface on the radiator or other parts, the parts are easy to process, and the cost is low; the volume of the lamp module is small, and the switching between the far and low beams is noiseless.

Description

technical field [0001] The present invention relates to a car lamp, in particular, the present invention relates to a car lamp module with an LED light source integrating far and near beams. Background technique [0002] With the application of LED light sources in car lights, the technology of car light modules is constantly being introduced, and the shapes and structures are becoming more and more diverse, and the volume and weight are getting smaller and smaller. [0003] Existing LED light source car light modules generally need to be partially aluminum-plated on the radiator, and the aluminum-plated surface on the radiator and the light-shielding plate cooperate to form the light shape of III area on the screen. The necessary condition is that there is The structure positions part of the light emitted by the light source to irradiate the position of the III zone. [0004] However, according to the existing far and near light integrated headlight module, the light shape...
