Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those skilled in the art's every other implementation obtained without creative efforts
Example, shall fall within the protection scope of the present invention.
Fig. 1 to Fig. 5 is please referred to, one embodiment of new type reflection and refractive optics TV lens in the embodiment of the present invention should
Lens include lens body 1, which is cubic rotary table 2 at cylindrical and its bottom, and the bottom of lens body 1 opens up
There is the first cavity 3, and the center of the first cavity 3 is located in 1 axial direction of lens body, the inner wall of the first cavity 3 constitutes incidence surface 31,
The center of incidence surface 31 is made of multiple equidistant concentric circles 51, to realize that preferably extension acts on to light.The four of first cavity 3
It is equipped with Fresnel ring 8 week, Fresnel line is distributed on Fresnel ring 8, Fresnel line plays focusing light effect, reduces light loss.
The top of the lens body 1 of the present embodiment offers the second cavity 4, and the inner wall of the second cavity 4 is reflecting surface 41, light
Line is reflected in lens interior via reflecting surface 41, which can be the face free curve TIR, realizes light total internal reflection.
In the present embodiment, the center of the first cavity 3 and the second cavity 4 is respectively positioned in 1 axial direction of the lens body, and thoroughly
Mirror is axially centrosymmetric along lens body 1.The regular texture that this center piles can guarantee that light is reflected through lens and reflect
Afterwards, light-emitting surface is wide, uniform in light emission, eliminates hot spot.
In the present embodiment, the side of lens body 1 is formed with the light-emitting surface 6 of the revolution bodily form, the radial section of light-emitting surface 6
Diameter extend from bottom to top and gradually become smaller along lens body 1 is axial, preferably semiellipse is spherical or hemispherical, out light
Face 6 is ellipsoidal surface or spherical surface.The light-emitting surface 6 of the revolution bodily form can play good disperse function to light.In order to enable expanding
Scattered effect is more uniform, and 6 center of light-emitting surface of the present embodiment is made of multiple equidistant concentric circles 52, to play preferably to light
Diffusion.
In the present embodiment, in order to facilitate the installation of, it is set on the cubic rotary table 2 of 1 bottom of lens body there are four positioning column 7,
Positioning column 7 is to facilitate installation to fix, and can play preferable locating effect at four angles of cubic rotary table 2.Certainly, if
It sets four positioning columns 7 to be used only for explaining the effect that the present embodiment facilitates installation to position, in order to realize more preferably installation positioning effect
Fruit can according to need the positioning column 7 of setting different number and different location.
In the present embodiment, optics TV lens 10 further include LED light source 20, diffuser plate 30 and reflective sheeting 40, the LED
Light source 20 is located at first cavity 3, and diffuser plate 30 is located at 10 top of lens, and reflective sheeting 40 is located at 10 bottom of lens.
In the specific implementation, LED light source emits beam, and is refracted into lens, part light via the incidence surface 31 of the first cavity 3
Line can directly reflect lens via light-emitting surface 6, and some light can be complete interior anti-via the reflecting surface 41 for being located at the second cavity 4
It penetrates, then by the Nie Feier ring optically focused of lens bottom and reflector reflection, reenters lens refraction, reflection, and from light out
Face 6 is projected, and is spread via diffuser plate.Divergence of beam is opened, is used by constantly reflecting, reflecting by the light of the present embodiment
Smooth surface 6 is wider, and light is more uniform out.
Due to the special construction of lens, pass through a LED light source, it will be able to light-emitting surface 6 and the out uniformity of light are widened, and
And the usage amount of lamp bead can also be reduced, reduce cost.
In conclusion new type reflection provided in an embodiment of the present invention and refracted light TV lens, LED light source are passed through saturating
Reflection, the refraction of each curved surface of mirror, then by reflective sheeting and diffuser plate, divergence of beam is opened, keeps light-emitting surface 6 wide, uniform in light emission, solution
Certainly existing optics TV lens light-emitting surface is narrow, the non-uniform technical problem of light efficiency can reach big face when not increasing lamp bead
Long-pending display effect.
