Description

A kind of iraser LED lens

Technical field

This utility model relates to LED lens technologies field, particularly relates to a kind of iraser LED saturating Mirror.

Background technology

LED lens can strengthen the service efficiency of light and luminous effect together with being i.e. closely connected with LED Rate, can use the optics of the optical field distribution of different lens change LED according to different effects System.

In prior art, iraser LED lens, when with the connection of LED lamp panel, connect not After closely or using for a long time, meeting generation gap at joint face, iraser LED light source sends Light can spill from gap, affect the normal use of equipment.

Utility model content

This utility model provides a kind of iraser LED lens, can prevent iraser LED light leak.

For reaching above-mentioned purpose, this utility model adopts the following technical scheme that

A kind of iraser LED lens, including lens body, described lens body includes incidence surface And exiting surface, described incidence surface offers receiving chamber, described receiving chamber is rectangular-shaped, described Accommodate and in the middle part of the roof in chamber, convex to form hemispherical convex surface, described receiving chamber to described exiting surface side Two relative edges of opening part are along being provided with multiple projection, and multiple projections are oppositely arranged two-by-two, described appearance Chamber opening part of receiving is not provided with two relative edges of described projection and is respectively equipped with inclined plane along place, multiple described It is equipped with reflecting layer in protruding and described inclined plane.

Further, described receiving chamber opening part two relative edges along on be respectively equipped with two described convex Rise, and described projection is positioned on two relatively short sides of described receiving chamber opening part.

Further, the cross section of described projection is rectangle.

Further, distance between projection described in relative two is 3～3.2 millimeters.

Further, distance between inclined plane edge described in two is 5～5.3 millimeters.

Further, the total height in described receiving chamber is 4.8～5 millimeters.

Further, the outer surface of described lens body is frosting.

This utility model compared with prior art has the advantage that and effect:

This utility model iraser LED lens, due to two relative edges of described receiving chamber opening part Along being provided with multiple projection, multiple projections are oppositely arranged two-by-two, and described receiving chamber opening part does not sets Put two relative edges of described projection and be respectively equipped with inclined plane along place, multiple described projections and described tiltedly Being equipped with reflecting layer on face, therefore, the light that iraser LED light source sends is along lens and LED When the joint face of lamp plate outwards penetrates, understand by the reflecting layer multiple reflections on multiple projections and inclined-plane, Gradually weaken so that light cannot be penetrated by the analysis of lens and the joint face of LED lamp panel, from And prevent iraser LED light leak.

Accompanying drawing explanation

In order to be illustrated more clearly that the technical solution of the utility model, required in embodiment being described below The accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is only this utility model Some embodiments, for those of ordinary skill in the art, on the premise of not paying creative work, Other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 1 is the cross section structure schematic diagram of this utility model iraser LED lens；

Fig. 2 is the upward view of this utility model iraser LED lens.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical solution of the utility model is carried out clearly Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of this utility model, and It is not all, of embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not having Make the every other embodiment obtained under creative work premise, broadly fall into the model of this utility model protection Enclose.

Fig. 1 is the cross section structure schematic diagram of this utility model iraser LED lens；Reference Fig. 1, Fig. 2, iraser LED lens, including lens body 1, described lens body 1 includes incidence surface 11 and exiting surface 12, described incidence surface 11 offers receiving chamber 2, described receiving chamber 2 is rectangular Body shape, convexes to form hemispherical convex surface to described exiting surface side in the middle part of the roof in described receiving chamber 2, Two relative edges of described receiving chamber 2 opening part are along being provided with multiple protruding 21, multiple protruding 21 two-by-two Be oppositely arranged, described receiving chamber 2 opening part be not provided with described protruding 21 two relative edges along place distinguish Be provided with inclined plane 22, multiple described protruding 21 and described inclined plane 22 on be equipped with reflecting layer.

This utility model iraser LED lens, two relative due to described receiving chamber 2 opening part Edge is provided with multiple protruding 21, multiple protruding 21 and is oppositely arranged two-by-two, and described receiving chamber 2 is opened Two relative edges being not provided with described protruding 21 at Kou are respectively equipped with inclined plane 22 along place, multiple described convex Rise 21 and inclined plane 22 on be equipped with reflecting layer, therefore, iraser LED light source sends Light is when outwards penetrating along the joint face of lens and LED lamp panel, and meeting is by multiple protruding 21 and tilts Reflecting layer multiple reflections on face 22, gradually weakens so that light cannot be by lens and LED lamp panel Joint face analysis at penetrate, thus prevent iraser LED light leak.

Preferably, as in figure 2 it is shown, two relative edges of described receiving chamber 2 opening part set respectively along upper There are two described protruding 21, and described protruding 21 are positioned at the two relatively long of described receiving chamber 2 opening part Bian Shang.Two pairs of projections 21 can make light line reflection repeatedly, simplifies and finish while preventing light from spilling Structure.

As in figure 2 it is shown, so that reflecting effect is more preferable, the described cross section of protruding 21 is preferably square Shape.

Specifically, distance between protruding 21 described in relative two is preferably 3～3.2 millimeters；Described in two Distance between inclined plane 22 edge is preferably 5～5.3 millimeters；The total height in described receiving chamber 2 is 4.8～5 millimeters；Thus can leave enough installing spaces to LED light source.

The outer surface of described lens body 1 can be that bright finish can also be for frosting.Preferably employ mill Sand face, frosting can use light evenly.

This utility model iraser LED lens can be used for infrared array video camera, infrared ball machine etc. Infrared monitoring device.

The above, detailed description of the invention the most of the present utility model, but protection of the present utility model Scope is not limited thereto, and any those familiar with the art discloses at this utility model Technical scope in, can readily occur in change or replace, all should contain in protection of the present utility model Within the scope of.Therefore, protection domain of the present utility model should be with described scope of the claims It is as the criterion.
