Description

A kind of improved lens of structure

Technical field

The utility model relates to backlight lens technologies more particularly to one kind to make outgoing light energy distribution uniformly saturating Mirror.

Background technique

In the backlight of the electronic products such as liquid crystal, need lighting device provide light source, lighting device often by LED and thoroughly Microscope group at, meanwhile, lens have the function of that the light for being irradiated LED is diffused as wide-angle so that outgoing light it is more uniform.So And in the case where liquid crystal display industry samples the background for requiring to be continuously improved, traditional downward back optical lens (CSP series) is easy to appear Energy tomography problem, cause optics taste be not easy to be received.

Summary of the invention

The utility model provides a kind of improved lens of structure, overcomes deficiency in the prior art.

In order to solve the above-mentioned technical problem, technical solution adopted in the utility model are as follows:

A kind of improved lens of structure, including lens body and pedestal, the lens body are arranged on the pedestal, institute Lens body is stated with a light-emitting surface and lens base, the middle part indent of the lens base has an incidence surface, the light-emitting surface The incidence surface is arranged in goes out light side, is being respectively the first radius distance and the second radius distance from lens base center Radial direction is provided with the groove that at least one circle cross section is triangle in section.

Further, first radius distance is 5.5-6.5mm, second distance 7.5-8.5mm.

Preferably, first radius distance is 6mm, second distance 8mm.

Further, the groove has the first inclined-plane and the second inclined-plane, and the width on first inclined-plane is 0.65- 0.75mm, the width on second inclined-plane are 0.2-0.25mm, and the height of the groove is 0.1-0.15mm.

Preferably, the width on first inclined-plane is 0.7mm, and the width on second inclined-plane is 0.22mm, the groove Height be 0.12mm.

Preferably, the circle number of the groove is two circles.

Preferably, the cross section of the light-emitting surface is in M type shape, and the incidence surface is in class bullet shape.

Preferably, the lens base outer profile is circle, radius size 9mm.

Preferably, the lens body and pedestal are integrally formed.

Preferably, it is provided on the lens base and inside contracts suspension column.

The utility model provides a kind of improved lens of structure, including lens body and pedestal, the lens body setting On the pedestal, the lens body has a light-emitting surface and lens base, and the middle part indent of the lens base has one to enter The light side out of the incidence surface is arranged in smooth surface, the light-emitting surface, is being respectively the first radius distance from lens base center Radial direction is provided with the groove that at least one circle cross section is triangle in the section of the second radius distance.The lens it is recessed LED light can be adequately reflected into light-emitting surface by slot structure, and have biggish light-emitting surface at energy position of fault, thus significantly Improve light-out effect.

Detailed description of the invention

Fig. 3 is partial enlargement diagram at the A of Fig. 1.

Specific embodiment

With reference to the accompanying drawing, the embodiments of the present invention is specifically illustrated, attached drawing is only for reference and illustrates use, not structure The limitation of pairs of the utility model patent protection scope.

As shown in Figures 1 to 3, the improved lens of a kind of structure, including lens body 2 and pedestal 1, the lens body 2 are set It sets on the pedestal 1, the lens body 2 has a light-emitting surface 22 and lens base 21, the middle part of the lens base 21 Indent has an incidence surface 211, and the light side out of the incidence surface 211 is arranged in the light-emitting surface 22, in from lens base 21 The heart be respectively in the section of the first radius distance and the second radius distance along radial direction be provided at least one circle cross section be three Angular groove 3.Specifically, first radius distance is 5.5-6.5mm, second distance 7.5-8.5mm.The present embodiment In, first radius distance is 6mm, second distance 8mm.

Specifically, the groove 3 has the first inclined-plane 31 and the second inclined-plane 32, and the width on first inclined-plane 31 is 0.65-0.75mm, the width on second inclined-plane 32 are 0.2-0.25mm, and the height of the groove 3 is 0.1-0.15mm.This reality It applies in example, the width on first inclined-plane 31 is 0.7mm, and the width on second inclined-plane 32 is 0.22mm, the height of the groove 3 Degree is 0.12mm.

In the present embodiment, the circle number of the groove 3 is two circles.

The cross section of the light-emitting surface 22 is in M type shape, and the incidence surface 211 is in class bullet shape.

21 outer profile of lens base is circle, radius size 9mm.

The lens body 2 and pedestal 1 are integrally formed.

It is provided on the lens base 21 and inside contracts suspension column 4.

Working principle: from LED be emitted light, by indent lens incidence surface, light by incidence surface diffusion, again It is spread through light-emitting surface, but some light is reflected onto lens base, inclined-plane is then formed by by groove at this time and is spread again To light-emitting surface, waste is avoided, further improves the energy tomography of a certain position of lens light-emitting surface.Meanwhile part LED light is from leaning on The side of nearly lens base sheds, and causes biggish waste, but by the reflection and refraction on groove inclined-plane, greatly reduces light Source waste, improves light extraction efficiency.

Above disclosed is only the preferred embodiment of the utility model, and the right of the utility model cannot be limited with this Protection scope, therefore equivalent variations made according to the patent scope of the utility model still belong to the model that the utility model is covered It encloses.
