Used as a kind of preferred technical scheme of this utility model, the radiating layer material is albronze material, and for thin Lamellar.

Used as a kind of preferred technical scheme of this utility model, the LED lamp is in semicircle shape, for highlighting.

Used as a kind of preferred technical scheme of this utility model, the LED lens include that material is transparent polymer material Lens body and material for translucent polymer material lens outer layer.

Used as a kind of preferred technical scheme of this utility model, each several part of the LED lens is connected into by junctional complex One entirety.

Used as a kind of preferred technical scheme of this utility model, the LED lens have original arc shell shape to be changed to Jagged employing fresnel lens structure.

Compared with prior art, the beneficial effects of the utility model are：The LED lens, by the setting of two-layer light collecting part, So that the spotlight effect of the LED lens is more preferably, effectively light source is gathered in wick axial location, tied by Fresnel lens The design of structure, the Absorption in lens on light source is reduced while reducing lens thickness, reduces material, setting by heat dissipating layer Put, the disperses heat for effectively producing LED, it is to avoid burn out LED because temperature is too high.

Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of this utility model protection.

Embodiment：

Fig. 1 is referred to, this utility model provides a kind of technical scheme：A kind of LED lens, including support 1, the and of LED lamp 2 Glass lens 3, the bottom of the support 1 is provided with heat sink 4, because its temperature is not with the size variation of the heat energy for being delivered to it, institute To be used to help radiate so as to stablize the operating temperature of LED lens, the upper surface of the support 1 is provided with heat dissipating layer 5, described to dissipate Thermosphere material is albronze material, and for flake, heat dissipating layer is connected by the inside of support 1 with the heat sink of downside, described The top of heat dissipating layer 5 is connected with the edge of glass lens 3, LED seat 6 is provided with inside glass lens 3, in the LED seat 6 Side is welded with LED lamp 2, and the LED lamp 2 is in semicircle shape, and for highlighting, the LED seat 6 passes through ceramic substrate 7 It is connected with heat dissipating layer 5.

The upper end of the LED lamp 2 is provided with the first light collecting part 8 and the second light collecting part 9, and first light collecting part 8 is just to LED The axis of wick 2 is arranged, for converging direction and close axis side that the LED light source sends towards the axis direction To light, second light collecting part 9 is arranged at the top of the first light collecting part 8, and second light collecting part 9 is around the first light collecting part 8 The loop configuration of setting, second light collecting part 9 is used to towards the axis direction of the LED light source converge to send from the LED light source The deviation axis light, first light collecting part 8 is integrated setting with the adjacent light collecting part 9, and LED lens have original Arc shell shape be changed to jagged employing fresnel lens structure, the LED lens include that material is transparent polymer The lens body 10 of material and the lens outer layer 11 that material is translucent polymer material, the light that LED lamp 2 sends is through saturating After mirror main body 10, then by the outgoing of lens outer layer 11.
