This research attempted simplifications to the LED street light for price competitiveness. The street light was simplified by replacing the SMPS with an IC driver on the PCB using an AC-type LED. The optical element that shape of a line-shaped lens covered LED crowded. Thus, this study aims to improve LED efficiency by using the minimum optical system. In order to satisfy the M3 regulation of street lighting at grade, the lens was divided into two parts depending on the forward direction of the light. Further, the changes in the number of LEDs located on part 1 and part 2 of the lens were analyzed. Through simulation, we determined the proper light distribution that meets M3 regulation of street lighting.
