Abstract
The utility model discloses a multi-color light-mixing condensing lens with small angle and high efficiency. A light emitting surface of the lens comprises a central light emitting surface and more than two annular light emitting surfaces which are distributed on the periphery of the central light-emitting surface and are different in height; and the central light emitting surface and the annular light emitting surfaces are formed by micro lens arrays. The light emitting surface of the lens is provided with a plurality of annular light emitting surfaces and is divided to form a step shape with more than two layers; and according to the light emitting surface with the stepped shape, excessive materials having no influence on the light direction are removed, and thus materials can be saved and the weight of the lens is reduced. The light emitting angle and the light-mixing uniformity are influenced by the curvature of micro lenses on the central light emitting surface and the annular light emitting surfaces. If the curvature radius is small, the light mixing effect is uniform and the light emitting angle is great; and if the curvature radius is great, the light mixing uniformity is poor and the light emitting angle is small. After light is distributed by the multi-color light-mixing condensing lens disclosed by the utility model, 50 percent of beam angles are within 20 degrees; and the multi-color light-mixing condensing lens is high in light emitting intensity and suitable for projection lamps for a longer distance.
Description
Technical field
The utility model relates to the LED light distribution structure, the high efficiency multiple color mixed light collector lens of especially a kind of low-angle.
Background technology
The LED Projecting Lamp (LED Downlight) be spotlight, projecting lamp, shot-light or the like again; Mainly be used for doing the usefulness of building decoration illumination; And commercial space illumination usefulness, ornamental composition is heavier, and its external form has the round also side of having; Because generally all must consider the reason of dispelling the heat, so its profile and traditional Projecting Lamp still have some differences.LED Projecting Lamp at present commonly used on the market is to select the 1W great power LED for use (each LED element can have high light efficiency lens of being processed by PMMA basically; Its main function is the light that secondary distribution LED sends; Secondary optics just); For commercial Projecting Lamp, rising angle and projection distance generally have requirement, and present Projecting Lamp rising angle and irradiation distance all do not reach requirement.
Summary of the invention
The utility model technical problem to be solved provides the high efficiency multiple color mixed light collector lens of a kind of low-angle, and rising angle is littler, and irradiation distance is farther.
For solving the problems of the technologies described above; The technical scheme of the utility model is: the high efficiency multiple color mixed light collector lens of a kind of low-angle; Said lens exiting surface comprises the center exiting surface and is distributed in the exiting surface peripheral annular exiting surface that is differing heights in center more than two that said center exiting surface and annular exiting surface are made up of microlens array.The lens exiting surface is provided with some annular exiting surfaces, the exiting surface of lens is divided into two-layer above stepped, and the exiting surface of this shape has been removed the excess stock that radiation direction not have influence, can save material, minimizing lens weight.Lenticular curvature on center exiting surface and the annular exiting surface can influence rising angle and even light mixing degree, and radius of curvature is little, and the mixed light effect is even, and rising angle is big; Radius of curvature is big, and the even light mixing degree is poor, and rising angle is little.After process the utility model carried out luminous intensity distribution, 50% beam angle was in 20 degree; Output intensity is high, is fit to throw more at a distance light fixture.
As improvement, outside by the lens centre, the height and the diameter of said annular exiting surface increase gradually.
As improvement, said lens exiting surface comprises four annular exiting surfaces.
As improvement, said lens are bowl-shape.
As improvement, said lens bottom is provided with the depression of ccontaining led light source.
As improvement, said led light source is made up of the different colours chip, and the emergent light shades of colour mixes behind the scioptics.
As improvement, said chip light emitting area is smaller or equal to 100mm2.
As improvement, said lenticular radius of curvature is 2 ~ 9mm.
The beneficial effect that the utility model is compared with prior art brought is:
1, light source can adopt the integrated LED of multicore sheet, and the multicore sheet can be a different colours, and the chip light emitting area is smaller or equal to 100mm2;
2, the lens exiting surface is stepped, removes the excess stock that radiation direction is not had influence, can save material, reduces lens weight;
3, the lenticular curvature on the lens exiting surface can influence rising angle and even light mixing degree, and radius of curvature is little, and the mixed light effect is even, and rising angle is big.Radius of curvature is big, and the even light mixing degree is poor, and rising angle is little;
4,50% beam angle is in 20 degree;
5, output intensity is high, is fit to throw more at a distance light fixture;
6, lens bright dipping diameter is less than 85mm;
7, the emergent light shades of colour mixes behind the scioptics.
