Abstract:
A lighting system includes various LED boards. The LED boards are connected to a power source via an LED driver that regulates power from the power source to the LED boards. The LED driver includes a positive output and a negative output. The positive output of the LED driver is connected to a positive connection point of a first LED board and the negative output of the LED driver is connected to a negative connection point of a last LED board to distribute power or current approximately evenly across the LED boards. Distributing power or current approximately evenly across the LED boards or balancing current through the LED boards can cause the brightness or intensity of various LEDs in the lighting system to be approximately the same.
