Integrated high-beam and low-beam automatic switching headlamp

Abstract

The invention discloses an integrated high-beam and low-beam automatic switching headlamp, which comprises a light distribution main lens, a directional light detector, a shell with protection and heat dissipation functions, a driving power supply, a control loop, a high-beam and low-beam LED light source and a connecting cable. The light distribution main lens is fixedly connected with the shellin a spinning mode. The directional light detector is inserted into an open hole of the light distribution main lens. The high-beam and low-beam LED light source, the driving power supply and the control loop are all fixed on the shell. One end of a connecting cable is connected with the driving power supply and the control loop, and the other end of the connecting cable penetrates through a cablelocking waterproof piece on the shell to be connected with an external automobile power supply loop. According to the invention, when motor vehicles running at night intersect with each other, the headlamps of the motor vehicles are automatically switched from high beam illumination to low beam illumination. Therefore, the dizziness of drivers of opposite coming vehicles caused by high beams of the motor vehicles running in opposite directions can be avoided. The possibility of traffic accident tragedies caused by dizziness is reduced.

Description

technical field [0001] The invention belongs to the field of motor vehicle exterior lighting, and in particular relates to an integrated far and near beam automatic switching headlamp. Background technique [0002] As a key component of the exterior lighting of motor vehicles, headlights have many advantages compared with current automotive interior and exterior lighting solutions, such as higher performance, longer life, and lower cost. This lighting method improves The aesthetics and performance of automotive lighting are compromised; driving LEDs directly from the car battery requires a DC / DC converter to regulate a constant LED current and protect the LEDs from the vagaries of the car battery bus. [0003] The traditional motor vehicle headlight assembly is a split design of the high beam and the low beam. When driving at night, the driver of the motor vehicle needs to switch the high and low beams. When the two vehicles meet, if the driver does not switch the high beam ...

[0003] The traditional motor vehicle headlight assembly is a split design of the high beam and the low beam. When driving at night, the driver of the motor vehicle needs to switch the high and low beams. When the two vehicles meet, if the driver does not switch the high beam Switching back to the low beam will cause the driver of the other motor vehicle to be dazzled and unable to see the road conditions clearly, thus causing traffic accidents
