Problems solved by technology

Especially when using halogen bulbs, because the brightness of halogen bulbs is low, low beams and high beams need to be used separately to meet the lighting needs of the vehicle during driving, high energy consumption and increased production costs
At the same time, the reliability of signal transmission in the existing lighting control system is low, and there are often failures that cannot transmit signals normally

Embodiment Construction

[0013] An integrated far and near beam lamp for vehicles, comprising a reflective bowl 68, the lamp body is installed in the reflective bowl 68, the lamp body is a xenon lamp, the light source of the xenon lamp has high brightness, and a single xenon lamp can meet the requirements of far and near light at the same time. Light needs. A support is provided at the mouth of the reflective bowl 68, and the support is connected to the drive shaft 54 ​​of the driving device 50. The drive shaft 54 ​​of the drive device 50 drives the support to make the reflective bowl 68 rotate around a horizontal axis perpendicular to the vehicle's driving direction. When the lamp body is tilted downward, it emits a low beam. On the contrary, when the lamp body is basically in a horizontal position, it emits a high beam. figure 1 , 2 , 3 shown.

[0014] combine figure 1 , 2 3. The support includes a first support 61 fixed at the mouth of the reflective bowl 68, the first support 61 is frame-shape...

Abstract

The invention relates to a vehicle high-low beam integrated light. The light comprises a reflector, wherein the light body is arranged in the reflector; a bracket is arranged at the opening of the reflector and is connected with a driving shaft of a driving device; and the driving shaft of the driving device drives the bracket to make the reflector swing up and down in a vertical direction. The invention also discloses a control system for the high-low beam integrated light which can ensure signal transmission and have high reliability. In the vehicle high-low beam integrated light, a high-low beam integrated light component integrates the conventional high-low beam lights so as to not only meet the requirement of lighting but also reduce energy consumption and production cost. Moreover, a vehicle controller and a headlight electric control unit (ECU) transmit a signal through a signal line and a controller area network (CAN) bus so as to ensure the reliability of signal transmission.

Description

technical field [0001] The invention relates to the field of automobile lighting, in particular to an integrated far and near beam lamp for a vehicle and a control system thereof. Background technique [0002] At present, most of the automotive lighting systems installed on vehicles use halogen headlights, and a small number of them use xenon headlights. Among them, halogen headlight bulbs are cheap and have low technical requirements, but the brightness of the light source is low and consume more energy; xenon headlight bulbs are expensive and have high technical requirements, but the brightness of the light source is better than that of halogen headlights, and it is more energy-saving and environmentally friendly. [0003] According to the usual configuration on the car at present, one group of low beam lights and one group of high beam lights are respectively installed on the vehicle body, and the low beam lights and the high beam lights are used as independent light sour...
