Description
Technical field
The present invention relates to lens technologies field, relate in particular to a kind of directional lighting polarisation LED lens.
Background technology
Along with power-type LED is more and more ripe for general lighting field, for reaching excellent fit light effect, adopted optical lens.LED optical lens is mainly used in optically focused, leaded light and the astigmatism of LED light source series of products.According to the angle design distribution curve flux of different LED emergent light, contribute to promote light extraction efficiency, the minimizing light loss of LED, change the optical field distribution of LED, and can be according to the secondary light-distribution lens of the different designs different angles of shadow surface.
Current lens majority is penetration lens, and when LED light is during through a curved surface of lens, light refraction can occur and optically focused, and when distance between adjustment lens and LED, the angle of emergent light also can change.But the lens flare through ordinary optical design is equally distributed at present, can not distribute according to the requirement of shadow surface.
Summary of the invention
For solving the problems of the technologies described above, the invention provides the accurate directional lighting of a kind of LED of realization light fixture, reduce light source power and can improve the directional lighting polarisation LED lens of illumination efficiency.
In order to achieve the above object, the present invention proposes a kind of directional lighting polarisation LED lens, comprises lens body, and the cross section of described lens body is crescent, and the inner surface of lens body is shaped face.
Preferably, the inner surface of described lens body is the arcwall face that curvature changes.
Preferably, the outer surface of described lens body is the arcwall face that curvature changes.
Preferably, the dead ahead of described lens body is penetration concentration structure.
Preferably, the wall thickness of described lens body is irregular distribution.
Preferably, the maximum flying height of the inner surface of described lens body is 3.72mm.
Preferably, the material of described lens adopts polymethyl methacrylate, Merlon or optical glass material.
Preferably, the hot spot of described lens outgoing is symmetrical Flower Print.

In order to make technical scheme of the present invention clearer, clear, below in conjunction with accompanying drawing, be described in further detail.
The specific embodiment
As Figure 1-Figure 5, the embodiment of the present invention proposes a kind of directional lighting polarisation LED lens, comprises lens body 1, and the cross section of described lens body 1 is crescent, and the inner surface 11 of lens body 1 is shaped face.Some described lens form module spreadlight lens 2.
Particularly, lens are to utilize refraction principle, and the light that can make spot light send converges or disperses, and play the effect that changes beam angle size, thereby reach, change by the lighting area according to surperficial and the object of brightness value.
In the present embodiment, the cross section of lens body 1 is crescent, and the wall thickness of lens body 1 is irregular distribution.
The inner surface 11 of lens body 1 adopts shaped face, the arcwall face that the inner surface 11 of lens body 1 changes for curvature, the outer surface of lens body 1 is the arcwall face that curvature changes, and forms thus special-shaped lens, and the maximum flying height h of the inner surface 11 of lens body 1 is 3.72mm.And at the dead ahead of lens body 1 penetration concentration structure, thereby the hot spot that can change LED optical lens distributes, and its principle is as follows:
In the dead ahead of lens body 1, with penetration optically focused, inwall adopts shaped face sidelight all can be collected and reflected away, and the overlapping of these two kinds of light just can obtain the most perfect light utilization and good hot spot effect.
First than the structure of existing LED optical lens, mostly existing optical lens is penetration lens and refraction-reflection lens, when penetration lens are light through a curved surface of lens can there is refraction and optically focused in light, and refraction-reflection lens are by cylindricality or tapered side, sidelight to be collected to reflect away again, the light that these two kinds of lens go out is all regular geometry, such as circle or rectangle etc.
And the spreadlight lens of the present invention's design is a kind of special-shaped lens, in dead ahead, with penetration optically focused, inwall adopts shaped face sidelight all can be collected and reflected away in the design of lens, and the overlapping of these two kinds of light just can obtain the special hot spot that design is wanted, mostly hot spot is symmetrical or asymmetric Flower Print.Compared to existing technology, the present invention program's tool has the following advantages: the light that luminous point sends can be irradiated according to definitive orbit; The many irregular light of filtering disturbs and makes shadow surface formation rule figure; Remove light pollution, improve illumination efficiency.
Wherein, for the material of lens, can adopt following three kinds:
Optical grade PMMA (polymethyl methacrylate, is commonly called as: acrylic), optical grade acrylic (PMMA), light transmittance is high, penetrance 93% left and right during 3mm thickness; But temperature can not surpass 80 ° (92 ° of heat distortion temperatures), and irradiation time is difficult for longly, otherwise can reduce light transmittance.
Optical grade material Polycarbonate (being called for short PC, Merlon), light transmittance is slightly low, penetrance 89% left and right during 3mm thickness; But temperature can not surpass 110 ° (135 ° of heat distortion temperatures).
Optical glass material, its advantage is: have the features such as light transmittance high (97%), heatproof be high, anti-aging.
Spreadlight lens of the present invention can, according to the difference of light fixture difference and use occasion, select to adopt above-mentioned three kinds of materials.
Spreadlight lens of the present invention, by changing lens shape, it is mainly the irregular distribution of inner guide lighting channel and lens wall thickness, with penetration optically focused, the shaped face of inwall can all be collected sidelight and reflect away in lens dead ahead, thereby makes light utilization that the overlapping of these two kinds of light can improve and good hot spot effect.
Therefore, the translucent effect of spreadlight lens is far longer than the translucent effect of ordinary optical lens, and can be according to the brightness requirement light distributed of shadow surface, reduce unnecessary indirect lighting, reduce light pollution, improve illumination efficiency, greatly reduce light source power, reduce light source cost, more energy-saving and cost-reducing.So the prospect of spreadlight lens will be more wide.
In addition solved, the problem of the accurate directional lighting of LED light fixture; Lens itself belong to precision optics accessory, therefore its required precision to mould is high, the present invention is because structural design is ingenious, can completely autonomous die sinking, after die sinking, both met the high efficiency of producing in enormous quantities, and also guaranteed the accuracy of spreadlight lens.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or flow process conversion that utilizes description of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
