Title:
LIGHT DISTRIBUTION METHOD FOR COB MODULE LED STREETLAMP LENS CAPABLE OF ILLUMINATING 3-5 LANES
Document Type and Number:
WIPO Patent Application WO/2015/109891
Kind Code:
A1
Abstract:
A light distribution method for a COB module LED streetlamp lens capable of illuminating 3-5 lanes is characterized in that light emitted by a COB module LED light source is firstly refracted by a water drop-shaped refractive lens (11) and then refracted for the second time by a light distribution curved lens (12), in order to obtain the optimal illuminating effect. The method lays a foundation for the use of a single COB module LED light source on urban roads, and has the advantages of being low in cost and high in efficiency.
