Description
Technical field
The utility model is related to lighting field, more particularly to a kind of LED flashlight lens.
Background technology
At present, typical flashlight optical element be mirror reflection efficiency in LED and reflector, reflector not
It is high so that the luminous component light loss of LED light source center is serious, so as to cause overall brightness to reduce, while the optically focused of reflector
Effect is poor, the light that sends can part it is scattered so that the flashlight range that lights is shorter, it is impossible to see the object of distant place clearly, be this we
A kind of LED flashlight lens are have developed, to solve problem present in transmission flashlight.
Utility model content
The purpose of this utility model is to provide a kind of LED flashlight lens suitable for LED flashlight, above-mentioned to solve
The problem of being proposed in background technology.
To achieve the above object, the utility model provides following technical scheme, a kind of LED flashlight lens, including lens
Body, the body bottom portion is provided with the accommodating cavity for being used for setting light source, it is characterised in that the lateral wall of the body is reflection
Face, the reflecting surface is shiny surface, and the body top surface is exiting surface, and the exiting surface is in cambered surface, and the exiting surface extends
Central surface at the top of fixed edge, the accommodating cavity is in pearl face, and the pearl face is set to shiny surface, and accommodating cavity side wall is light
Sliding surface.
It is preferred that, the lens body is transparent PMMA materials.
It is preferred that, the lens body is integrally formed.
A kind of LED flashlight, including light source and a kind of LED flashlight lens described in claim 1, it is characterised in that
The light source is arranged in the accommodating cavity of the lens body.
It is preferred that, the light source is arranged on the center in the accommodating cavity.
Compared with prior art, the beneficial effects of the utility model are：A kind of LED flashlight lens of the present utility model,
Lens body sets accommodating cavity, and LED/light source is arranged in accommodating cavity, central surface is set at the top of accommodating cavity, central surface can be very
The light of good collection light source center part outgoing, so as to improve the brightness of flashlight, the exiting surface is set to cambered surface, reduces
The angle of light extraction, improves the luminous range of flashlight, while the design of cambered surface can avoid shrinking when producing injection, and
Shorten injection cycle.

Embodiment
The technical scheme in the utility model embodiment is clearly and completely described below, it is clear that described reality
It is only a part of embodiment of the utility model to apply example, rather than whole embodiments.Based on the embodiment in the utility model,
The every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, belongs to this reality
With novel protected scope.
Referring to Fig. 1, a kind of LED flashlight lens, including lens body 1, the bottom of body 1, which is provided with, to be used to set light
The accommodating cavity 2 in source, it is characterised in that the lateral wall of the body 1 is reflecting surface 11, and the reflecting surface 11 is shiny surface, described
The top surface of body 1 is exiting surface 12, and the exiting surface 12 is in cambered surface, and the exiting surface 12 extends fixed edge 13, the accommodating cavity 2
The central surface at top is in pearl face 22, and the pearl face 22 is set to shiny surface, and accommodating cavity side wall 21 is shiny surface.It is described go out
Smooth surface 12 is set to cambered surface, relative to the exiting surface for being set to plane, reduces rising angle, so as to improve the effect of optically focused
Really, the range of flashlight is added, while the design of cambered surface can avoid shrinking when producing injection, and injection week is shortened
Phase, the fixed edge 13 that the exiting surface 12 extends is stuck in torch tub, the body 1 is fixed well, institute
The central surface for stating the top of accommodating cavity 2 is set in pearl face, and the pearl face 22 can effectively collect the central part of light source 3 and separate
The light penetrated, it is to avoid light stream mistake, so that the brightness that flashlight sends light is improved, the reflecting surface 11, pearl face 22 and accommodating cavity
Side wall 21 is disposed as shiny surface so that the light source 3 polarisation rule in body 1 described in whole lens, improves lens
Spotlight effect.
It is preferred that, the lens body is transparent PMMA materials, with higher optics penetrance and spotlight effect.
It is preferred that, the lens body is integrally formed, and technique is simple, and production efficiency is high.
A kind of LED flashlight, including light source and a kind of LED flashlight lens described in claim 1, it is characterised in that
The light source is arranged in the accommodating cavity of the lens body, and the light that light source center is sent effectively is collected, so as to improve
Brightness.
It is preferred that, the light source is arranged on the center in the accommodating cavity so that the light that light source is sent is by saturating
It is evenly distributed during mirror and light beam rule.
Although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art
Say, it can still be modified to the technical scheme described in foregoing embodiments, or which part technical characteristic is entered
Row equivalent substitution, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvements made etc. all should
