Abstract
The utility model relates to a fresnel lens technical field, concretely relates to fresnel lens of high -efficient spotlight, including the central transparent surface that is used for pass through away the central ray that the light source sent, the first outward appearance portion of all sidelight aline central ray transmission direction total reflection of being used for sending the light source and be located first outward appearance and central transparent surface between the anchor ring, first outward appearance is spliced by a plurality of planes and to be formed. The utility model discloses a fresnel lens of high -efficient spotlight adopts central transparent surface to pass through away the central ray that the light source sent, and all sidelight aline central ray transmission direction total reflection of adopting first exterior inferior officer's light source of being formed by the concatenation of a plurality of planes to send, compare for only passing through away central ray among the prior art, the utility model discloses the light that passs through away is more, and all gathers to the central ray direction to make the light gathering efficiency of lens higher, it is also stronger through the light intensity of these lens.
Description
Technical field
This utility model is related to Fresnel Lenses technical field and in particular to a kind of Fresnel Lenses of high-effective concentration.
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, this is because the week side of boss light that LED light source sends is directly from Fresnel Lenses the week side of boss transmission
Go out, the deviation of directivity that the central ray transmission that the direction that this week side of boss light transmission is gone out is sent with light source is gone out too big it is impossible to
Form the consistent light in direction, the week side of boss light that transmission is gone out is side leakage light it is impossible to utilize, thus causing to waste.
Utility model content
The purpose of this utility model is for deficiency of the prior art, and provides a kind of Fresnel of high-effective concentration saturating
The light of script side leakage can be converged with central ray, improve light gathering efficiency by mirror.
For achieving the above object, the technical scheme that this utility model is taken is：A kind of Fresnel Lenses of high-effective concentration, bag
Include the center transparent surface gone out for the central ray transmission sending light source, be used for the week side of boss light that light source is sent to center
First outer exterior portion of light transmission direction total reflection and the anchor ring being located between the first outer exterior portion and center transparent surface, outside first
Exterior portion is formed by multiple plain splice.
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.
Wherein, described anchor ring is set to frosting near the one side of light source.
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 outside 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.
The beneficial effects of the utility model：
A kind of Fresnel Lenses of high-effective concentration of the present utility model, center light light source being sent using center transparent surface
Line transmission is gone out, and using the week side of boss light being sent light source from the first outer exterior portion of multiple plain splice to central ray
Transmission direction is totally reflected, and only goes out to compare by central ray transmission with respect in prior art, this utility model transmission is gone out
Light is more, and all assembles to central ray direction, so that the light gathering efficiency of lens is higher, by the light intensity of this lens
Higher.
Brief description
Fig. 1 is a kind of structural representation of the Fresnel Lenses of high-effective concentration of this utility model.
Fig. 2 be a kind of Fresnel Lenses of high-effective concentration 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 high-effective concentration of this utility model, as shown in Figure 1 to Figure 2, including
The center transparent surface 1 gone out for the central ray transmission sending light source 4, be used for the week side of boss light that light source 4 is sent in
First outer exterior portion 21 of heart light transmission direction total reflection and the anchor ring being located between the first outer exterior portion 21 and center transparent surface 1
3, the first outer exterior portion 21 is formed by multiple plain splice.
A kind of specific embodiment of the Fresnel Lenses of high-effective concentration of this utility model, using center transparent surface 1 by light
The central ray transmission that source 4 sends is gone out, and using being sent light source 4 by the first outer exterior portion 21 of multiple plain splice
The week side of boss light is totally reflected to central ray transmission direction, only goes out to compare by central ray transmission with respect in prior art, this
The light that utility model transmission is gone out is more, and all assembles to central ray direction, so that the light gathering efficiency of lens is higher,
Light intensity after this lens for the light source 4 is also higher.
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.
In the present embodiment, described anchor ring 3 is set to frosting near the one side of light source 4.This frosting can prevent light from
The intersection of anchor ring 3 and the first outer exterior portion 21 is gone out through anchor ring 3 transmission.
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 outside 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.
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.
