Abstract:
The invention relates to a light distribution method for a COB module LED street lamp lens capable of illuminating 3 or 5 lanes. The light distribution method is characterized in that the light emitted by a COB module LED light source is firstly refracted by a drop-shaped refraction lens (11) and then refracted secondarily by a light distribution curved surface lens (12) to achieve an optimal irradiation effect. The light distribution method provides a foundation for the use of a single COB module LED light source in an urban road, and has the advantages of low cost and high efficiency.
