An integrated control system for vehicle lighting components

Abstract

The invention relates to the field of vehicle lighting control, and specifically discloses an integrated control system for vehicle lighting components, comprising an input module, a constant voltage driving module, a constant current driving module, a control module and an LED module; the input module is connected to an external power supply through a first interface , the input module transmits the input power supply voltage to the constant voltage drive module, and the constant voltage drive module performs preset constant voltage processing on the input power supply voltage and transmits it to the LED module; the control module is connected to the LED module through the second interface control signal, the control module converts the input control signal into a control current and transmits it to the constant current drive module, and the constant current drive module performs preset constant current processing on the input control current and transmits it to the LED module. In the integrated control system for vehicle lighting components of the present application, the voltage output is first controlled by the constant voltage circuit, and then the current output is controlled by the constant current circuit, so as to achieve the effect of constant voltage and constant current.

Description

technical field [0001] The invention relates to the field of vehicle lighting control, in particular to an integrated control system for vehicle lighting components. Background technique [0002] Cars may include light assemblies that provide several different light functions. For example, light assemblies typically provide high beam and / or low beam for forward driving functions, daytime running light (DRL) functions, and positionlight functions. The Drive Forward function illuminates the roadway in front of the vehicle so that the driver can see the roadway in low light conditions. The light provided by the DRL function makes the vehicle visible to oncoming vehicles during the day. The position light function provides light so that the vehicle can be seen by oncoming vehicles in low light conditions or at night. Because the position light function operates at night or in low light conditions, the position light function requires a relatively low light output to be visibl...

Problems solved by technology

[0003] However, each light is controlled by the power line output by its own switch, so there will be a large number of wiring harnesses, complicated installation and layout, and a large number of interfaces, which will lead to problems of high failure rate. There are many driving circuits for each light. The required size of the board is larger, the cost is higher, and the circuit loss is larger

[0004] At the same time, each wiring harness needs to be arranged concealedly to the corresponding working position. Not only are there many lines, it is troublesome to conceal, and once there is a problem on the line, it is difficult to check

And too many lines can easily cause voltage drop
