Problems solved by technology
As far as the W-level low beam is concerned, this implementation method requires a large number of LED light sources, and the cost is high; according to different driving conditions, the control system is complicated to control the on and off of each LED; and the arrangement of a large number of LED light sources also makes the model large group size

Embodiment Construction
[0026] Such as figure 1 , 2 , 3, the present invention discloses a car light module (hereinafter referred to as the car light module) that can meet the ECE standard W-level low beam requirements, which is used for the lighting of cars and placed in the car headlights. Realize the integrated lighting functions of single low beam and far and near beam. The vehicle lamp module includes a low beam LED circuit board 9 , a low beam concentrator 10 and a lens 5 fixedly arranged in sequence along the light path direction. Under normal circumstances, the light emitted by the low-beam LED light source (on the low-beam LED circuit board) is refracted and totally reflected by the low-beam concentrator, the light is gathered and emitted forward, and part of the light passes through the low-beam After the condenser is focused on the second focal point, it is directly emitted, and then enters the lens, and part of the light meets the lower surface of the low-beam concentrator to form total...

The invention relates to a car lamp module capable of meeting W-level near-light requirements of ECE standards. The car lamp module is fixedly provided with a near-light LED circuit board, a near-light condenser and a lens sequentially in a direction of a light path, wherein a transparent light shading plate capable of automatically rotating is further arranged between the near-light condenser and the lens; the transparent light shading plate at least can be stopped on a first position and a second position; at the first position, the transparent light shading plate is positioned on the light path between the near-light condenser and the lens for shading the front end of the near-light condenser, weakening light, which corresponds to a segment 10 area in a near-light light shape, emitted by near light, and reducing a brightness value to be lower than 7100 cd; at the second position, the transparent light shading plate deviates from the light path between the near-light condenser and the lens for enabling the light which corresponds to the segment 10 area to normally irradiate, and reducing the brightness value of the light to be lower than 12300 cd. Conversion between the light shape of W-level near light and light shape of near light of other levels can be realized without a great number of LED light sources; and an implementation way is simple, and size is small.
Description
technical field [0001] The invention relates to a car lamp module that can meet the requirements of ECE standard W-class low beam, and belongs to the technical field of car lamps. Background technique [0002] The continuous development of LED light source car light modules has produced more diverse demands, which can meet the lighting requirements under different road conditions. For roads with a lot of water, conventional low beams are irradiated on the water accumulation area in front of the vehicle. Due to the reflection of water, it is easy to dazzle the driver and the driver of the oncoming vehicle, which brings hidden dangers to driving safety. In the EU car lamp standard ECE R123-2013, for harsh driving environments, especially rainy roads and watery road conditions, a special W-class car lamp standard for the low beam function of the front lighting system has been formulated. [0003] At present, there are very few car light modules that can meet the ECE standard W...
