| Abstract |
This study is to develop and experiment with a controller for LED module diagnosis and current balancing. For this, to the respective modules used in the lighting devices were applied with current balancing to keep the heat of all LED elements, By having the existing constant current converted replaced with a constant voltage converter, and by using a current balancing circuit, the respective modules’ current control can be enabled. The currents of the respective modules are to be determined by the PWM Duty of the MCU. The fact that the current control for the respective modules through the current balancing circuit is possible has the following advantages: first, an improvement in the current imbalance due to the tolerance of the LED element. Second, the resolution to the excessive set power for the LED module and concentrated current in existing systems when open/short states occur to the LED module. |
