Abstract

To solve the problem of rapid reduction of brightness of the conventional left/right LED headlights of an automobile due to the characteristics of an LED module when an automobile battery is low after discharged while operating at rated voltage, and the problem of overheating in the left/right LED headlights of an automobile using excessive current, and in the constant voltage and constant current components, the present invention provides a simultaneous control module for left/right LED headlights of automobile for controlling identical luminance of left/right LED headlights. The simultaneous control module comprises a simultaneous control module (200) for left/right LED headlights of an automobile, which is connected to one side of an automobile ECU, senses the output current that passes through a plurality of parallel-type LED modules arranged in parallel and connected to one side of the left/right LED headlights of an automobile, and then switches the input current being inputted back into the plurality of parallel-type LED modules, according to a reference voltage for LED module operation, so that the brightness of the left/right LED headlights of an automobile is maintained identically. The present invention can operate without a relay device, thereby reducing the volume of the control module for left/right LED headlights of an automobile by 70% or more the volume of a conventional control module, select the brightness of the left/right LED headlights of an automobile from three stages according to the weather outside and the driving location, measure the current flowing in the plurality of left/right LED headlights of an automobile arranged in parallel, and maintain the identical brightness of the left/right LED headlights of an automobile without using constant voltage and constant current components by controlling the PWM pulse width until the microcomputer unit acknowledges the low battery status.
