When (plane) is seen to incidence surface, it may appear that lofty round clear area, middle position light intensity are higher than surrounding light intensity, influence light efficiency
Fruit, to affect the validity of shooting.
Utility model content
For this purpose, the mirror center portion the technical problem to be solved by the utility model is to conventional flash lamp lens is divided into convex lens
Mirror, easily forms round clear area, and influence is taken pictures authenticity, and to propose a kind of light-out effect evenly, no clear area improves
The flashlight lens of shooting effect.
In order to solve the above technical problems, the technical solution of the utility model is：
The utility model provides a kind of flashlight lens comprising lens body, the lens body include being set to sudden strain of a muscle
The light-emitting surface of the incidence surface of light light source and the separate flash light source, the incidence surface are Fresnel Lenses face, institute
It is plane to state light-emitting surface.
Preferably, the lens body has an accommodating cavity for housing the flash light source, the accommodating cavity
Top is the incidence surface.
Preferably, the Fresnel Lenses face is made of a series of sawtooth concentric rings being sequentially arranged, the same sawtooth
Two neighboring sawtooth spacing is 0.05-0.5mm in ring.
Preferably, a height of 0.001-0.5mm of sawtooth tooth.
Preferably, the fleam is not less than 28 degree.
Preferably, the tooth top radius of the sawtooth is not less than 0.02mm, the radius of flute of tooth is not less than 0.01mm.
Preferably, the sawtooth height of center saw-tooth ring is less than the sawtooth height of external saw-tooth ring.
Preferably, the lens body include the first lens section and be shaped at the top of first lens section the
Two lens sections, the incidence surface are set to first lens section, and the light-emitting surface is set to second lens section.
The above-mentioned technical proposal of the utility model has the following advantages compared with prior art：
Flashlight lens described in the utility model comprising lens body, the lens body include being set to flash of light
The light-emitting surface of the incidence surface of light source and the separate flash light source, the incidence surface is Fresnel Lenses face, described
Light-emitting surface is plane.The middle position of its incidence surface is also Fresnel Lenses face, does not contain smooth convex lens part, lines one
Cause property is good so that without round clear area when from light extraction towards in terms of incidence surface, light extraction uniform intensity, effect is good, so that answering
It is stronger with the mobile terminal shooting validity of the flashlight lens, in addition, the flashlight lens aesthetics higher, more metal
Texture.
