Description
(1), technical field: the utility model relates to a kind of lens and lampshade, particularly a kind of special-shaped lens and LED lampshade.
(2), background technology: along with the development of LED technology, increasing lamp adopts great power LED luminous tube to manufacture, especially in factory building and outdoor illumination, because site environment is more severe, while using general incandescent lamp and energy-saving fluorescent lamp, not only the efficiency of lamp is low, the life-span is short (although the efficiency of energy-saving fluorescent lamp is higher, but its life-span is shorter), and the mechanical strength of two kinds of lamps is all poor, has had a strong impact on consumer's use, therefore, LED lamp demonstrates its advantage more and more.Yet, on illumination mode, also there are some shortcomings in existing LED lamp, because the light distribution of common on the market LED lamp is generally lambertian distribution, hot spot is circular, for the light fixture of numerous large-sized workshops workshop and warehouse lighting, this kind of illumination mode exists that non-uniform light, light pollution are serious, light utilization efficiency is low, causes serious dazzle in certain angle, impact is normal produces and the defect of work.
(3), utility model content:
The technical problems to be solved in the utility model is: not enough for prior art, a kind of special-shaped lens and LED lampshade of simple in structure, the good illumination effect that can make LED lamp are provided.
The technical solution of the utility model:
, contain a positive N frustum of a pyramid, the side of this positive N frustum of a pyramid is outwardly curved surface, at the middle part of the upper surface of this positive N frustum of a pyramid, is provided with a pit, N is more than or equal to 3 natural number.
Pit is square pit.
N is 3, or is 4, or is 5, or is 6.
Curved surface is arc-shaped curved surface.
The material of special-shaped lens is transparent material.Special-shaped lens is injection molded by high perspex.
A kind of LED lampshade that contains described special-shaped lens, contain cover body and the frame that is located at its surrounding, cover body contains M identical special-shaped lens and a base plate, M special-shaped lens is all arranged on the upper surface of base plate, M special-shaped lens on base plate by being regularly arranged into an array, the surrounding of base plate is connected with frame, and M is more than or equal to 1 natural number.
M special-shaped lens is evenly arranged on base plate, contains gapped between adjacent special-shaped lens.
Array is rectangular array or square array, and described frame is provided with locating dowel and through hole is installed.
Between M special-shaped lens and base plate, being integral type structure, is fabricated structure or integral structure between base plate and frame.
The material of M special-shaped lens and base plate is transparent material.During actual production, can be by whole LED lampshade
Injection molded by high perspex.Perspex can be realized higher light transmission, and deformation can not occur at higher temperature.
During actual this LED lampshade of use, LED light source plate can be arranged on to the back side of LED lampshade, make each LED lamp on LED light source plate just in time be arranged in the pit on special-shaped lens, like this, the light that LED lamp sends sends from the bottom even of special-shaped lens after special-shaped lens refraction and reflection, forms a uniform hot spot.
The beneficial effects of the utility model:
1,, in special-shaped lens of the present utility model, the light that LED lamp sends is first from the positive N frustum of a pyramid
It is inner that face enters the positive N frustum of a pyramid, then, part light sends from positive N frustum of a pyramid bottom surface after superrefraction, and another part light first passes through the offside reflection of the positive N frustum of a pyramid after superrefraction again, finally also from positive N frustum of a pyramid bottom surface, sends, like this, special-shaped lens has almost been collected all light that LED lamp sends, and then makes it again evenly to divide and send, therefore, special-shaped lens can effectively improve the luminous defect of LED lamp, improves the illumination effect of LED lamp.
2, in LED lampshade of the present utility model, if special-shaped lens adopts positive tetragonous cone table structure, M
Individual special-shaped lens is pressed rectangular arranged on base plate, the light that LED lamp sends just can form a uniform rectangular light spot after special-shaped lens, M rectangular light spot combined and just formed a sheet of uniform irradiated region, improved like this light utilization efficiency, reduced light pollution, reduced the dazzle of light fixture, made the illumination effect of LED lamp better.
3, of the present utility model simple in structure, manufacture convenient, production cost is low.
