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
The present invention relates to a kind of optical lens that can be used for hybrid light source, belong to optical field.How to be applicable to light
The laser flashlight in source or other multiple light courcess products.
Background technology
Along with the raising of socioeconomic development and living standards of the people, the kind of light source is day by day various, and the application mode of single light source also more and more can not meet people's demand, so the application of the hybrid light source such as laser flashlight is also more and more extensive.Existing laser flashlight generally has the structure of following two kinds: 1. only have a kind of LASER Light Source or single LED light source, realize the effect of indication, but light source is more single; 2. LASER Light Source centering, a plurality of LED are around surrounding, and this kind of scheme no doubt realized the mixing of two light sources, but cannot regulate the light intensity in spot size and unit area as illuminating LED, and usable range is subject to restriction to a certain extent.In addition, two kinds of light sources are directly exposed in air, and dust easily enters light source and interiors of products, not easy to clean.
Summary of the invention
The present invention aims to provide a kind of optical lens that can be used for hybrid light source, with what solve that prior art exists, cannot regulate the light intensity in spot size and unit area, and usable range is subject to restriction to a certain extent; And light source is directly exposed in air, dust easily enters light source and interiors of products, not the problem of easy to clean.
Technical scheme of the present invention is: a kind of optical lens that can be used for hybrid light source, it is characterized in that, and on the convex surface summit of plano-convex lens, be provided with the top plane parallel and coaxial with the baseplane of this plano-convex lens.
Center in the baseplane of this optical lens is provided with coaxial cylindrical bore.
At the outside surface of this optical lens or/and the inside surface of cylindrical bore carries out coating film treatment as required.
Described plated film is anti-reflection film or reflectance coating.
The material of this optical lens comprises glass, crystal or plastics, or selects as required the light transmissive material of other refractive indexes.
Advantage of the present invention is: by the convex surface summit at plano-convex lens, be provided with the top plane parallel and coaxial with the baseplane of this plano-convex lens, change the distance of lens and light source, the light that LED light source or other light sources can be sent is focused, the beam quality that is positioned at the logical radiant in center is not changed, having realized the mixing of coaxial multiple light courcess uses, use convenient flexibly, (refer to that lens outer surface is an integral body, outside surface does not have hole in the not perforate of sealing of this optical lens design.On market, on the lens of some product, punch, airborne like this dust can be fallen on internal light source), avoided light source directly to contact with air, be easy to cleaning.
Accompanying drawing explanation
Fig. 1 is structural front view of the present invention;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the axial cut-open view of an application example of the present invention (with hybrid light source combination).
In figure: 1. optical lens; 11. baseplanes; 12. top planes; 13. cylindrical bore; 2.LED light source; 3. LASER Light Source; 4. LED pedestal that can be integrated with other light sources.
Embodiment
Referring to Fig. 1 and Fig. 2, a kind of optical lens that can be used for hybrid light source of the present invention, is characterized in that, this optical lens 1 is on the convex surface summit of plano-convex lens, to be provided with the top plane 12 parallel and coaxial with the baseplane 11 of this plano-convex lens.The size of baseplane 11 and top plane 12 diameters, the curvature of the curvature portion of plano-convex lens can, according to the material decision of optical lens therewith of the angle of divergence of central light source light beam, specifically determine according to actual service condition.
On the baseplane 11 of the optical lens 1 in above-described embodiment, can have the cylindrical bore 13 coaxial with baseplane 11, cylindrical bore 13 diameters and the degree of depth can and need to design according to the type of light source.During light scioptics, have certain loss, lens are thinner, and the loss of light is just fewer, so the object of cylindrical bore 13 is set, is to make lens center lead to the attenuation of light part, reduce the light loss of central light source when luminous as far as possible.
The material of the optical lens in above-described embodiment can be glass, crystal or plastics, also can select as required the light transmissive material of other refractive indexes.
The outside surface of the optical lens 1 in above-described embodiment (removing the inside surface of cylindrical bore 13) is or/and the inside surface of cylindrical bore 13 can carry out coating film treatment as required.Conventional anti-reflection film or reflectance coating for example, plated film effect is that the light that light source is sent carries out anti-reflection or reflection.Coating Materials is conventional material.
The present invention can be directly used on coaxial multiple light courcess laser flashlight or other multiple light courcess products, and the central shaft of optical lens 1 is coaxial with other light sources central shaft.Also lens can be fixed in the adjusting seat of adjustable focus, like this when changing the distance of lens and light source, be positioned at light (wavelength depends on the needs) this plane of process that the logical radiant of multiple light courcess product center sends, light beam can not change, but the light that LED light source or other light sources send is focused, having there is variation in hot spot, makes to throw light on convenient flexible.
As shown in Figure 3, the structure of an application example of the present invention and hybrid light source combination, this hybrid light source is comprised of LED light source 2, LASER Light Source 3 and LED pedestal 4, on the top of LED pedestal 4, along circumference, several LED light sources 2 is housed, and LASER Light Source 3 is housed in the center pit of LED pedestal 4 and forms.Optical lens 1 of the present invention is arranged on the top of this hybrid light source, and the light beam that LASER Light Source 3 is sent (central authorities two rays) is vertically through not changing after the baseplane 11 of optical lens 1 and top plane 12.And the light that LED light source 2 around sends focuses through the curved surface of optical lens 1, there is variation in hot spot.By adjusting optical lens 1 and the distance of hybrid light source, can be met the light beam of different needs, make to throw light on convenient flexible.
