Embodiment Construction

[0029] Below in conjunction with accompanying drawing, technical scheme of the present invention is described further:

[0030] The invention discloses an energy-saving lighting system for automotive LED self-adaptive headlamps based on micro-element energy mapping, which includes four lighting modules: a cut-off line light module, a widened light module, a strong light module and a sign light module. type module.

[0031] The cut-off line light type adopts a direct projection structure, as attached figure 1 As shown, the light emitted by the LED (1) is refracted by the inner surface (3) and the outer surface (4) of the lens (5) to form the cut-off line light pattern expected by the design, while the large-angle light emitted by the LED (1) is in the parabola Under the converging effect of the reflector (2), it is concentrated in the area near the optical axis Z, and then refracted to the front of the vehicle by the inner surface (3) and the outer surface (4) of the lens.

Abstract

An energy-saving lighting system for automotive LED adaptive headlights based on micro-element energy mapping is described, which is mainly used for energy-saving lighting of automotive headlights adapted to different road conditions. The system includes four lighting modules, namely cut-off line light module, widened light module, strong light module and sign light module. These four modules can be superimposed to achieve the requirements of ECE123 regulations through a certain LED power distribution. C-level light type, V-level light type, E-level light type and W-level light type. The average light energy utilization rate of the system reached 62%.

Description

technical field [0001] The invention relates to the field of automobile lighting, in particular to a design of an energy-saving lighting system for automobile LED self-adaptive headlights based on micro-element energy mapping. Background technique [0002] With the development of automobiles towards high speed, comfort, energy saving and environmental protection, people put forward higher and higher requirements for the safety and energy saving performance of automobile lighting. That is to say, good headlights should be able to provide safe lighting for driving without dazzling pedestrians and oncoming vehicles. At the same time, the lighting system should also have better energy-saving performance. [0003] However, due to the singleness of traditional car headlights that follow the changes of the body, the limitations of low beam and high beam lighting modes, low beam and high beam light types, it is difficult to meet the driver's requirements for car lighting in most cas...
