LED (light-emitting diode) light source upper beam and lower beam integrated automobile lamp module

Abstract

An LED (light-emitting diode) light source upper beam and lower beam integrated automobile lamp module is characterized in that an upper beam LED circuit board (5) and a lower beam LED circuit board (8) are arranged behind a condenser 1 respectively, and a reflection mirror comprises a first grade reflection mirror (10) and a second grade reflection mirror (9), which are used for forming a lower beam light shape. The first grade reflection mirror (10) can form the spreading width of the lower beam light shape independently, the second grade reflection mirror (9) increases the number of ray of light forming the lower beam light shape, and part of reflected light is used for forming a III region of the lower beam light shape. The ray of light emitted from an LED light source on the lower beam LED circuit board (8) is reflected by the first grade reflection mirror and the second grade reflection mirror, most ray of light therein is emitted after refracted by a lens (4) and forms a spreading width (5-1) of the lower beam light shape on a screen, the other part of ray of light is emitted from the lens (4) after reflected and refracted by the condenser to form a stop line (5-2) of the lower beam light shape and the III region (5-3). According to the invention, a square aluminizing surface does not need to be made on a radiator or other parts, the parts are simple to machine, and the cost is lower; the volume of the automobile lamp module is smaller, and the switching between the upper beam and lower beam has no noise.

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...
