Abstract
In this paper, a freeform reflector is designed for low road lighting. In the case of low road lighting, which requires light distribution over a wide lane compared to the height, it is difficult to match uniformity, compared to existing road lighting. To satisfy road lighting grade M3, the reflector was divided into nine parts, and the inclination of the reflecting surface was changed to have the desired light distribution. The fitted curves were drawn based on each point, following the formula that was derived. Through the Street Light Simulation of LightTools, we confirmed that it meets the M3 road lighting standard; we then made it directly and satisfied the lighting grade on an actual road, proving the validity of the design result.
