Abstract
The utility model relates to a combined lens which comprises a lens supporting frame and a plurality of single lenses, wherein each single lens is provided with an edge; grooves matched with the edges are formed in the lens supporting frame; the edge of each single lens is joined with the corresponding groove to fix the single lens on the lens supporting frame; preferably, the single lenses are welded on the lens supporting frame through an ultrasonic welding device. According to the combined lens, the cost can be lowered; a product can be diversified in a combineded way, lenses of different angles can be combined on the same frame to achieve different effects, only the frame is required to be redesigned to adapt to changes in product shape, and a frame die is only required to be dimensionally accurate, but not required to reach an optical level, so that the combined lens is low in cost.
Description
Technical field
The utility model relates to LED light source lighting field, particularly relates to a kind of combined LED lens.
Background technology
LED lamp is widely used in various occasions but because LED lamp is directive property light source, and major part needs adapter lens to change optic angle, to improve light utilization efficiency and to reach efficient illumination and show with required light.Need to or adopt discrete lens for the box-like mould of the single opener of every sample product at present, separate type lens need complicated assembling.
The lens that shaping volume is larger need the ejaculation time more of a specified duration so that the distortion of its shrink reduction portion just can maintain its optical design angle, therefore though integrated form eyeglass can economization built-up time, but must open new die and be high-accuracy optical mould, uneconomical and consumes resources, during production, cost is not low and take a large amount of die sinking time yet.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provide a kind of can high-speed production, rapid-assembling can reach the Combined lens of integrated eyeglass effect.
For achieving the above object, technical solution adopted in the utility model is as follows.
A kind of Combined lens, comprise lens supporting frame and some single lens, described in each, single lens have an edge, on described lens supporting frame, be provided with the groove matching with described edge, single lens being fixed on lens supporting frame by described edge and described groove described in each.
Further, described single lens pass through ultrasonic wave welding device welding on described lens supporting frame.
Further, described single lens are made by PPA plastics.
Further, described single lens are made by PC plastics.
The beneficial effects of the utility model are: Combined lens of the present utility model adopts knockdown mode to reach the effect of integrated eyeglass, can high-speed production, rapid-assembling, and can fast Development in the cost-effective while.Because the mould of each single lens optics completes, single a large amount of lens can be applied mechanically and be combined in various framework to adapt to the demand of different lamps, various angles also can change lens and change, and do not need out a plurality of moulds, when light fixture changes, only need open cheap frame mold.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of Combined lens of the present utility model.
In figure, 1-lens supporting frame, mono-lens of 2-, 3-edge, 4-groove.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Combined lens of the present utility model as shown in Figure 1, comprise lens supporting frame 1 and some single lens 2, each single lens 2 all has an edge 3, on lens supporting frame 1, be provided with the groove 4 matching with edge 3, single lens 2 being fixed on lens supporting frame 1 by edge 3 and groove 4.As preferably, single lens 2 by ultrasonic wave welding device welding on lens supporting frame 1.The material of lens can be PPA or PC plastics.
Combined lens of the present utility model is manufactured by following step:
1) prepare a plurality of single lens pieces, described in each, single lens add an edge when die sinking;
2) on lens supporting frame, open the corresponding groove in some and described edge;
3) described edge is engaged in the groove on lens supporting frame, single lens are loaded on lens supporting frame;
4) use ultrasonic wave welding device by single lens welding described in each on described lens supporting frame.
Combined lens of the present utility model, for LED light source illumination, adopts knockdown mode to reach the effect of integrated eyeglass, can high-speed production, rapid-assembling, and can fast Development in the cost-effective while.Because the mould of each single lens optics completes, single a large amount of lens can be applied mechanically and be combined in various framework to adapt to the demand of different lamps, various angles also can change lens and change, and do not need out a plurality of moulds, when light fixture changes, only need open cheap frame mold.
This Combined lens can also be saved cost, can make product diversification by combination, same framework different angles lens capable of being combined to be to reach different effects, and product design changes and only need again open framework and can adapt to, it must not be precisely optical grade that frame mold only needs size, therefore cheaply many.
The foregoing is only preferred embodiment of the present utility model, be not used for limiting practical range of the present utility model; If do not depart from spirit and scope of the present utility model, the utility model is modified or is equal to replacement, all should be encompassed in the middle of the protection domain of the utility model claim.
Claims (4)
