Abstract

The utility model relates to an LED lamp lens which comprises a base (1), a lens plate (2) fixed on the base (1), and supporting legs (3) fixed under the base (1), and is characterized in that the exterior of the lens plate (2) consists of an outer side surface (21) and an outer top (22); and the interior of the lens plate (2) comprises a refracting layer I (23), a refracting layer II (24) and a refracting layer III (25). The LED lamp lens has the advantages that by utilizing the characteristic of asymmetric optical convergence angle, the LED lens has the function of directional refraction and brightness correction for light passing through the lens, so that an LED street lamp can irradiate with even brightness and has uniform light shape, and the number of needed LED light-emitting components is obviously reduced.

Description

LED lamp lens

Technical field

The utility model relates to a kind of LED lamp lens, relates in particular to a kind of LED lamp lens of big lighting angle.

Background technology

Along with the progress in epoch and the maturation of technology, the manufacturing technology of light emitting diode is showing improvement or progress day by day in recent years, and advantages such as the brightness height that it has, power saving, life-span length display, and have been widely used in the lighting field of light fixture.

Yet, though the appearance of the existing high light large power product of LED lamp at present, but the monomer whose luminosity is still limited, can't directly apply to illumination, common way is that a plurality of LED light-emitting components are lined up on the same plane that array is arranged on equal height, in a concentrated manner to the demand of certain regional cover with satisfied illumination, the light that all LED light-emitting components are projected can be contained a specific region scope, so for light-emitting zone and the projected area that improves each LED light-emitting component in the array better, its front end all is provided with special LED lamp lens usually, yet existing LED lamp lens are because the defective of design, though LED lamp light concentration degree after its projection increases, but because its lighting angle is generally less, cause the illumination of the light beam that the array LED lamp finally projects too concentrated, problems such as effective area is little, and hot spot is inhomogeneous.

The utility model content

The purpose of this utility model is to provide a kind of LED lamp lens, so that solve problems such as LED lamp lens lighting angle is less in the prior art, illumination is too concentrated, effective area is little, hot spot is inhomogeneous.

The utility model discloses a kind of LED lamp lens, it comprises base and the lens that is fixed on the base, and the feet that is fixed on the base below, the outside of lens is to be made of lateral surface and outer top, the inside of lens is to be made of refracting layer one, refracting layer two and refracting layer three.Design by such multilayer refracting layer can make the light by LED lamp lens be reflected by multilayer, can obtain bigger more uniform range of exposures after seeing through LED lamp lens at last.

Further, lateral surface is a cylindrical sides, outer top is the truncated cone-shaped top, folding refracting layer one, refracting layer two and refracting layer three sectional structure on the lens fore-and-aft direction designs for middle " V " type that is down, refracting layer one, refracting layer two and refracting layer three sectional structure on the lens left and right directions is the refracting layer of " M " type of middle indent, and refracting layer one is positioned at refracting layer two, and refracting layer two is positioned at refracting layer three.

By refracting layer one, refracting layer two and refracting layer three at the cutaway view of fore-and-aft direction as can be known, middle each refracting layer is down " V " type and designs, and can make whole optical path obtain by a larger margin diffusion at fore-and-aft direction by each refracting layer.

By refracting layer one, refracting layer two and refracting layer three are at the cutaway view of left and right directions as can be known, each refracting layer that middle each refracting layer is " M " type design of indent can make whole optical path obtain restriction in left and right directions output, for narrow angle penetrates, help concentrating of light beam, reach the effect of homogeneous and bright, whole optical path figure is analyzed as can be known, the scope of the light irradiation that the LED lamp of last entire belt the utility model LED lamp lens sends presents an ellipse, can make whole road surface all be capped by the LED lamp that a plurality of band the utility model LED lamp lens are set on same road surface, arrive the effect of basic dull thread blind area.

Compare with prior art, the utlity model has following advantage:

The beneficial effects of the utility model are: by utilizing the characteristic of asymmetric optics convergent angle, feasible light by LED lamp lens carries out the function of directed refraction and brightness correction, make the LED street lamp carry out even brightness irradiation and light shape even, required LED light-emitting component quantity can obviously reduce.

The specific embodiment

Below in conjunction with accompanying drawing, specify the utility model.

As Fig. 1-Figure 5 shows that structure of this LED lamp lens, the utility model discloses a kind of LED lamp lens, it comprises base 1 and the lens 2 that is fixed on the base 1, and the feet 3 that is fixed on base 1 below, the outside of lens 2 is to be made of lateral surface 21 and outer top 22, and the inside of lens 2 is to be made of refracting layer 1, refracting layer 2 24 and refracting layer 3 25.The LED lamp is set at base 1 and is fixed between the lens 2 on the base 1, and the refraction that the light that the LED lamp sends will pass through refracting layer 1, refracting layer 2 24 and refracting layer 3 25 arrives the road surface at last.

Lateral surface 21 is cylindrical sides, outer top 22 is truncated cone-shaped tops, refracting layer 1, refracting layer 2 24 and refracting layer 3 25 sectional structure on the lens fore-and-aft direction designs for middle " V " type that is down, refracting layer 1, refracting layer 2 24 and refracting layer 3 25 sectional structure on the lens left and right directions is the refracting layer of " M " type of middle indent, and refracting layer 1 is positioned at refracting layer 2 24, and refracting layer 2 24 is positioned at refracting layer 3 25.

Be illustrated in figure 6 as by the index path on the utility model LED lamp lens fore-and-aft direction, as we know from the figure, refracting layer 1, refracting layer 2 24 and refracting layer 3 25 sectional structure herein design for middle " V " type that is down, can make whole optical path obtain by a larger margin diffusion at fore-and-aft direction by each refracting layer.

Be illustrated in figure 7 as by the index path on the utility model LED lamp lens left and right directions, as we know from the figure, refracting layer 1, refracting layer 2 24 and refracting layer 3 25 sectional structure herein are " M " type design of middle indent, each refracting layer can make whole optical path obtain restriction at left and right directions, for narrow angle penetrates.Whole optical path figure is analyzed as can be known, the scope of the light irradiation that the LED lamp of last entire belt the utility model LED lamp lens sends presents an ellipse, can make whole road surface all be capped by the LED lamp that a plurality of band the utility model LED lamp lens are set on same road surface, arrive the effect of basic dull thread blind area.
