Abstract In this parer, the optical properties of the 54[W] LED module have confirmed by changing the angles of LED modules for street light applications. The angle of LED module changed from the 0[˚] to 6060[˚] varying by 20[˚] as horizontal direction θ₁. Morever, the angle of LED module changed from the 0[˚] to 15[˚] varying by 5[˚] as vertical direction θ₂. As a result of simulation, the average illumination was about 17[lux] and the overall illuminance unifonnity was 0.29 for a 10.39[m] long and 6[m] wide illuminance area at height of 6[m], which is acceptable for street lighting illumination in the Illuminating Engineering Society[IES] standard.
