Abstract

The utility model relates to an asymmetric lenticular LED road lamp. In order to reach the requirements of lighting brightness and evenness index, the majority of the existing road LED lamps adopt reflecting shade structures, which has the disadvantage that the direct light and the reflected light are easy to produce a bright band at the junction on the ground, resulting in uneven brightness on the ground. The utility model aims to develop an asymmetric lenticular LED road lamp. The lamp comprises LEDs (6) which are distributed and fixed on a profile lamp body, and is characterized in that anasymmetric optical lens (5) capable of evenly distributing the light is fixed on each LED (6). The asymmetric lenticular LED road lamp has the functions of reducing light loss and improving the lighting brightness of the ground and the lighting evenness, and is convenient for large-scale production. The asymmetric lenticular LED road lamp is not limited to lighting on roads and is widely applicable for lighting in tunnels and other places.
