Coats in this reflection, and faces its light-emitting area to have the diamond surface reflection cover, when LED photo source transmitted light, will concentrate backward completely by the diamond surface unification refraction backward front end opens the mouth to launch, will promote the optical efficiency, because and complete photo source after diamond curve refraction projects, therefore namely can adjust this point source smoothly because of the change diamond surface's curvature/area/arrangement way the smooth shape, will be helpful in the simplified overall headlight's structure and the manufacture cost
