Side be light reflecting surface, provided with reflection plated film；The top surface of lens body is exiting surface；The crown center of the cavity is provided with
One unthreaded hole, unthreaded hole penetrate the top surface and cavity of lens body along the vertical direction；The top surface centre position of the lens body is provided with
One concave station, concave station is recessed from the top surface of lens body to the internal direction of lens body, in the central axis and unthreaded hole of concave station
Mandrel line overlaps；The anti-dazzling screen is made up of light-proof material, and anti-dazzling screen is installed on the concave station.
Preferential, when the anti-dazzling screen is installed on the concave station, the upper surface of anti-dazzling screen flushes with lens body top surface.
Preferential, the concave station is circular concave station, and the anti-dazzling screen is the circular anti-dazzling screen matched with concave station.
Preferential, the diameter of the anti-dazzling screen is more than the unthreaded hole.
Preferential, the lens body side is provided with metallic reflection plated film.
Preferential, the anti-dazzling screen is the anti-dazzling screen of black.
Preferential, the anti-dazzling screen bonding is installed on concave station.
Preferential, the anti-dazzling screen engaging is installed on concave station.
A kind of lens combination of anti-dazzle of the present utility model, including two independent mounting assemblies, one are lens master
Body, lens body are rotationally symmetric body.In use, LED light source is located in cavity, light is through in cavity interior walls entrance lens main body
Portion；After the first time refraction of cavity interior walls, the side wall of light directive lens body；Side wall is light reflection surface, and light is by side
After the reflection of wall, launch towards the top surface of lens, and be emitted through lens top surface.Light positioned at the LED light source in unthreaded hole direction is straight
Connect and projected upwards inside unthreaded hole, and blocked and sponged by anti-dazzling screen, the anti-dazzling screen of black is easier to absorb light, will not
The secondary reflection or transmission for causing light form interference light.Concave station is coaxially disposed with unthreaded hole, anti-dazzling screen and concave station form fit
Installation, it is advantageous in that, the axial location that anti-dazzling screen easily can be aligned to unthreaded hole is installed, it is not easy to which side is moved, and is adapted to
Manufactured in lot-size.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment lens combination；
Fig. 2 is the index path of the utility model embodiment lens combination.
Embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
As illustrated, a kind of anti-glare lens system of the present embodiment, including two independent mounting assemblies, one are
Mirror main body 1, secondly being anti-dazzling screen 2, lens body 1 is rotationally symmetric body.
Wherein lens body 1 includes bottom surface, peripheral side 12 and top surface 13.
The bottom surface of lens body 1 is provided with the cavity 11 for being used for accommodating LED light source 3, and cavity 11 is from the bottom surface of lens body 1
Between position be recessed to the internal direction of lens body, the inwall of cavity 11 is incidence surface, and incidence surface is smooth surface, LED light
The light in source is injected inside lens body from incidence surface.
The side 12 of lens body 1 is reflecting surface, and lens body has a symmetrical side 12 that rotates in a circumferential direction, side 12 it is outer
Surface is provided with reflective coating, and plated film is preferably metal coating, and the light of entrance lens main body is after side 12 is reflected towards lens
Top surface 13 projects.
The top surface 13 of lens body is exiting surface, and exiting surface is smooth surface, and light transmittance is good.
There is a unthreaded hole 14 on lens body 1, unthreaded hole 14 is along the vertical direction vertically through the He of top surface 13 of lens body
The crown center of cavity 11 so that the top of cavity 11 connects with lens superjacent air space, and unthreaded hole is pore.
The top surface centre position of lens body 1 is provided with a concave station 15, and concave station 15 is from the top surface of lens body 1 to lens master
The internal direction depression of body, the central axis of concave station 15 overlap with the central axis of unthreaded hole 14, and anti-dazzling screen 2 is installed on concave station 15
It is interior, and anti-dazzling screen 2 is installed with the form fit of concave station 15；And because concave station 15 and unthreaded hole 14 are coaxially disposed, can be easily
The axial location that anti-dazzling screen 2 is aligned to unthreaded hole is installed.
The diameter of anti-dazzling screen 2 is more than unthreaded hole 14, when anti-dazzling screen 2 is installed on the concave station 15, the upper surface of anti-dazzling screen 2 with
The top surface of lens body 1 flushes.Anti-dazzling screen 2 is made of light-proof material, such as black plastic, is easier to sponge center method
The too strong light of line.
Anti-dazzling screen 2 is preferential to be installed on concave station by the way of bonding, can use the side of engaging in other embodiments
Formula.
The anti-glare lens system of the present embodiment, light is through cavity interior walls entrance lens body interior；Through cavity interior walls
After reflecting for the first time, the side wall of light directive lens body；Side wall is light reflection surface, and light is after the reflection of side wall, direction
The top surface transmitting of lens, and be emitted through lens top surface.Light positioned at the LED light source in unthreaded hole direction is upward directly from unthreaded hole inside
Project, and blocked and sponged by anti-dazzling screen, the anti-dazzling screen of black is easier to absorb light, will not cause the secondary counter of light
Penetrate or transmit and form interference light.Concave station is coaxially disposed with unthreaded hole, and anti-dazzling screen and concave station shape Matching installation, it is advantageous in that,
The axial location that anti-dazzling screen easily can be aligned to unthreaded hole is installed, it is not easy to which side is moved, and is suitable for lot-size production system
