Abstract
The utility model relates to a technical field, fresnel lens technical field, concretely relates to prevent fresnel lens of edge leakage, include the anchor ring that is used for the central transparent surface that passs through away the central ray that the light source sent and is used for the permanent center transparent surface, the anchor ring is close to the one side of light source and establishes to the frosting. Compared with the prior art, the utility model discloses a prevent fresnel lens of edge leakage establishes to the frosting through the one side with being close to the light source on the anchor ring to can prevent well that light from passing through away through the anchor ring from the juncture of anchor ring with central transparent surface.
Description
Technical field
This utility model is related to Fresnel Lenses technical field and in particular to a kind of Fresnel Lenses of lateral leakage protection.
Background technology
Fresnel Lenses is a kind of magnifier, and the light being usually used in sending LED light source is diffused.Existing Fresnel is saturating
Mirror occurs the phenomenon of corner light leak, and specifically, existing Fresnel Lenses includes the central ray transmission for sending light source
The center transparent surface gone out and the anchor ring for fixed center transparent surface, the material due to anchor ring is transparent material, and it can
Printing opacity, but because anchor ring is used for fixed center transparent surface, there is intersection in anchor ring and center transparent surface, so through center
The light of transparent surface has one and goes out from anchor ring transmission through described intersection, causes the problem of light side leakage.
Utility model content
The purpose of this utility model is for deficiency of the prior art, and provides a kind of Fresnel of lateral leakage protection saturating
Mirror, can prevent light from going out from anchor ring transmission.
For achieving the above object, the technical scheme that this utility model is taken is: a kind of Fresnel Lenses of lateral leakage protection, including
For the central ray transmission center transparent surface gone out sending light source and the anchor ring being used for fixed center transparent surface, described
Anchor ring is set to frosting near the one side of light source.
Wherein, also include first being totally reflected for the week side of boss light sending light source to central ray transmission direction
Outer exterior portion, the first outer exterior portion around center transparent surface and is fixed on anchor ring, and the first outer exterior portion is formed by multiple plain splice.
Wherein, described Fresnel Lenses also includes the second outer exterior portion setting gradually from inside to outside and the 3rd outer exterior portion, the
In the periphery of the first outer exterior portion, the second outer exterior portion and the 3rd outer exterior portion are both secured to anchor ring to two external portion, the second outer exterior portion
Form by multiple plain splice with the 3rd outer exterior portion.
Wherein, described center transparent surface is provided with multiple salient points near the one side of light source, so that transmiting through face from center
The light going is evenly distributed.
The beneficial effects of the utility model:
A kind of Fresnel Lenses of lateral leakage protection of the present utility model, by being set to grind the one side near light source on anchor ring
Sand face, so as to prevent light from going out through anchor ring transmission from the intersection of anchor ring and center transparent surface well.
Brief description
Using accompanying drawing, the utility model is described in further detail, but the embodiment in accompanying drawing is not constituted to of the present utility model
Any restriction, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to following attached
Figure obtains other accompanying drawings.
Fig. 1 is a kind of structural representation of the Fresnel Lenses of lateral leakage protection of this utility model.
Fig. 2 be a kind of Fresnel Lenses of lateral leakage protection of this utility model in light move towards schematic diagram.
Reference:
1- center transparent surface, 11- salient point, the outer exterior portion of 21- first, the outer exterior portion of 22- second, the outer exterior portion of 23- the 3rd, 3- annulus
Face, 4- light source.
Specific embodiment
With the following Examples this utility model is further described.
A kind of specific embodiment of the Fresnel Lenses of lateral leakage protection of this utility model, as shown in Figure 1 to Figure 2, including use
In the central ray transmission center transparent surface 1 gone out sending light source 4 with the anchor ring 3 that is used for fixed center transparent surface 1, institute
The one side stating anchor ring 3 near light source 4 is set to frosting.
A kind of specific embodiment of the Fresnel Lenses of lateral leakage protection of this utility model, by by anchor ring 3 near light
The one side in source 4 is set to frosting, so as to prevent light from the intersection of anchor ring 3 and center transparent surface 1 through annulus well
Face 3 transmission is gone out.
In the present embodiment, also include being all-trans to central ray transmission direction for the week side of boss light sending light source 4
The the first outer exterior portion 21 penetrated, the first outer exterior portion 21 around center transparent surface 1 and is fixed on anchor ring 3, and the first outer exterior portion 21 is by many
Individual plain splice forms.So the week side of boss light that light source 4 sends can be totally reflected to central ray transmission direction, so that thoroughly
The light gathering efficiency of mirror is higher, and light intensity after this lens for the light source 4 is also higher.
In the present embodiment, described Fresnel Lenses is also included outside the second outer exterior portion 22 and the 3rd of setting gradually from inside to outside
Exterior portion 23, the second outer exterior portion 22 is located at the periphery of the first outer exterior portion 21, and the second outer exterior portion 22 and the 3rd outer exterior portion 23 are both secured to
Anchor ring 3, the second outer exterior portion 22 and the 3rd outer exterior portion 23 are formed by multiple plain splice.Second outer exterior portion 22 and the 3rd appearance
The setting in portion 23 can improve light gathering efficiency further.
In the present embodiment, described center transparent surface 1 is provided with multiple salient points 11 near the one side of light source 4, so that saturating from center
The light that the face transmission of mistake is gone out is evenly distributed.
Finally it should be noted that above example is only in order to illustrating the technical solution of the utility model, rather than to this reality
With the restriction of novel protected scope, although having made to explain to this utility model with reference to preferred embodiment, this area general
Lead to it will be appreciated by the skilled person that the technical solution of the utility model can be modified or equivalent, without deviating from this
The spirit and scope of utility model technical scheme.
