LED LAMP BRIGHNESS MAINTENANCE SYSTEM AFTER FAULT DETECTION OF SERIAL LED LAMP FOR VEHICLE

摘要

The present invention relates to a system for maintaining the brightness of an LED lamp after detecting a serial LED lamp failure for a vehicle, and when the failure of a vehicle LED lamp provided inside the vehicle is provided, the brightness of the LED lamp is maintained through detection and control of a microcontroller. An object of the present invention is to provide an LED lamp brightness maintenance system after detecting a failure of a serial LED lamp for a vehicle that can be maintained. To this end, after detecting a series LED lamp failure for a vehicle according to the present invention, the LED lamp brightness maintenance system adjusts the DC voltage input from the battery of the vehicle according to the number of LED lamps to be driven and then outputs it to a plurality of LED lamps. -DC converter; A plurality of LEDs (LEDs) provided in series, and operated by an output voltage from the DC-DC converter, an LED lamp that provides lighting in the vehicle; Connected to the DC-DC converter and LED lamp, the forward voltage of the LED lamp is checked to determine whether the LED is shorted, and accordingly, the output voltage of the DC-DC converter is adjusted to maintain the same brightness of the LED lamp. It is configured to include; a microcontroller to control so that.
