A vVehicle light assembly integrated control system

Abstract

The invention relates to the field of vehicle lightlamplight control, and particularly discloses a vehicle lamplightlight assembly integrated control system which comprises an input module, a constant-voltage driving module, a constant-current driving module, a control module and an LED module. Wherein tThe input module is connected with an external power supply through a first interface, the input module transmits accessed power supply voltage to the constant-voltage driving module, and the constant-voltage driving module performs preset constant-voltage processing on the input power supply voltage and then transmits the power supply voltage to the LED module; the control module is connected with a control signal through a second interface, the control module converts the connected control signal into a control current and transmits the control current to the constant-current driving module, and the constant-current driving module performs preset constant-current processing on the input control current and then transmits the control current to the LED module. According to the integrated control system for the vehicle lamplight assemblyvehicle light assembly integrated control system, the voltage output is controlled by the constant-voltage circuit firstly, then current output is controlled by the constant-current circuit, and therefore thus the constant-voltage and constant-current effects are achieved.

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] A car may include a light assembly that provides 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 position light functions. The forward driving function illuminates the roadway ahead 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 marker light function provides light that makes your vehicle visible to oncoming vehicles in low-light conditions or at night. Because the position marker light function operates at night or in low light conditions, the position marker light function requires a relatively low lig...

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
