Improper beam patterns on vehicle lights have major implications for the level of driving safety. This beam pattern control technique has been developed to improve driving safety. Most of them use additional components that increase power costs. In LED-based light sources, the design of LED arrays can increase the level of lighting and expand the transmission area. A large transmitting area is needed, but in a turn of the road, conditions are only needed based on the direction of the vehicle. Therefore, in this study, a system was designed to regulate LED beam patterns based on the direction of the vehicle. The main objective is to reduce power consumption so that it is more environmentally friendly and supports green technology programs. The control process was done by adding control components that work based on the direction of the vehicle that is read by the direction sensor. The digital control algorithm was implemented on the Altera DE-0 Nano FPGA with controls using fuzzy logic. The memory resources needed for implementing this system are 145 logic in the form of the loop up tables and 102 registers with a total power of 2 mW. This control module is able to provide a better focus of lighting and power efficiency up to 53% compared to a system without control.
