In order to utilizing the light flux reasonably and effectively, the LED reflector which is designed according to light reflection principle, makes the light emitted from LED resource spread in a specific direction through reflection. The problems about LED oblique illumination are described in the paper. By comparing the optical properties of elliptical and parabolic and using the optical modeling software, a compound trough reflector is designed. The irradiance map of optical simulation shows that a uniform rectangular spot is shaped on the lighting plane and the optical efficiency reach up to 72.3%.
