Embodiment Construction
[0015] see figure 1 and figure 2 , an optical lens that can be used for mixing light sources according to the present invention is characterized in that the optical lens 1 is provided with a top plane 12 parallel and coaxial with the bottom plane 11 of the plano-convex lens at the apex of the convex surface of the plano-convex lens. The size of the diameters of the bottom plane 11 and the top plane 12, and the curvature of the curved surface of the plano-convex lens can be determined according to the divergence angle of the light beam of the central light source and the material of the optical lens, specifically according to the actual use situation.
[0016] The bottom plane 11 of the optical lens 1 in the above embodiment may have a cylindrical hole 13 coaxial with the bottom plane 11. The diameter and depth of the cylindrical hole 13 can be designed according to the type and needs of the light source. There will be a certain loss when light passes through the lens. The th...
