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...

Abstract

An optical lens capable of being used for mixed light sources is characterized in that a top plane parallel to and coaxial with a bottom end plane of a planoconvex lens is arranged at the convex side top of the planoconvex lens. The optical lens has the advantages of achieving mixing use of multiple coaxial light sources, adopting planoconvex lens which processes the convex side top into the plane parallel to the plane, changing the distance between the lens and the light sources, being capable of focusing light emitted by a light-emitting diode (LED) light source or other light sources, enabling light beam quality of light through light sources at the center not to change, being more convenient and flexible in lighting and use, avoiding direct contact of the light sources and products and air and being easy to clean.

Description

technical field [0001] The invention relates to an optical lens which can be used for mixing light sources and belongs to the field of optics. Suitable for multi-light [0002] source laser flashlight or other multi-light source products. Background technique [0003] With the development of social economy and the improvement of people's living standards, there are more and more types of light sources, and the application of a single light source is increasingly unable to meet people's needs. Therefore, the application of mixed light sources such as laser flashlights is becoming more and more extensive. Existing laser flashlights generally have the following two structures: 1. There is only one laser light source or a single LED light source to realize the indication function, but the light source is relatively single; 2. The laser light source is placed in the center, surrounded by multiple LEDs, Although this kind of solution realizes the mixing of two light sources, the...
