Description
Technical field
The utility model relates to the technical field of road lighting, specifically a kind of double polarization opticals applied to guard rail lamp
Lens group.
Background technique
Important component of the LED light lens as LED lamp, its functionality are rationally to handle LED's itself
It shines, the optical requirement of different application is met by lens.
Guard rail lamp is to provide the light of viaduct road and its ring road illumination, with national basis Facilities Construction and changes
That makes puts more effort, and the market demand of guard rail lamp is also increasing year by year.What the application of guard rail lamp had not only been beautified the environment
Effect also has increasingly higher demands to the functionality of illumination.LED guard rail lamp uses line type moulding, and lamp installation is in road
On protective fence, bilateral cloth lamp.
Since its mounting height is lower, need light uniform irradiation as far as possible to road surface to reach such purpose, lamps and lanterns gesture
Necessity increases the elevation angle.But if increased using the traditional street lamp optical plan elevation angle, along be that dazzle value increases, it is right
It shines in driver into uncomfortable visual experience, also increases security risk.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of double polarization optical lens groups applied to guard rail lamp.
The utility model is adopted the technical scheme that solve technical problem present in well-known technique:
Double polarization optical lens groups applied to guard rail lamp of the utility model, first including road surface two sides are arranged in is saturating
Mirror and the second lens, each lens respectively include bottom plate, driving light distribution surface and vertical light distribution face again, driving light distribution surface and vertically match
Smooth surface is separately positioned on bottom plate, and the polarisation for light distribution surface of driving a vehicle is consistent with road surface direction with light direction, the polarisation in vertical light distribution face
Vertical with road center line direction with light direction, the driving light distribution surface of the first lens and the second lens is hung down relative to the center on road surface
Face is symmetrical, and the vertical light distribution face of the first lens and the second lens is symmetrical relative to the center vertical plane on road surface；First lens and
The polarisation of two lens is consistent with the direct motion direction of vehicle with light direction, and the distribution curve flux maximum value for light distribution surface of driving a vehicle is driving side
To.
The utility model can also use following technical measures:
The driving light distribution surface is convexed to form by the mirror surface of each lens towards road surface side, and vertical light distribution face is by each lens
Mirror surface away from road surface side, which is recessed, to be formed；The LED lamp bead of guard rail lamp is correspondingly arranged in the recess in vertical light distribution face.
Side setting positioning fixed column of the bottom plate away from road surface.
The mirror surface that the curvature mirror that the driving light distribution surface corresponds to vehicle direct motion direction is less than the retrograde direction of vehicle is bent
Rate, the curvature mirror of vertical light distribution face upper end are less than the curvature mirror of lower end.
The utility model has the advantages and positive effects of:
In double polarization optical lens groups applied to guard rail lamp of the utility model, symmetrically arranged first lens and second
The polarisation of lens is mainly displaced to the direct motion direction of vehicle with light direction.Based on such light type, just it is able to obtain at the lamps and lanterns elevation angle
To increase, more light are just able to add among road, to obtain better uniformity effect.
Detailed description of the invention
Fig. 1 is one group of first lens and the second lens in double polarization optical lens groups for guard rail lamp of the utility model
Top view；
Fig. 2 is the side view of the first lens in double polarization optical lens groups applied to guard rail lamp of the utility model.
Specific embodiment
The technical solution of the utility model is described in detail below by way of the drawings and specific embodiments.
As depicted in figs. 1 and 2, double polarization optical lens groups applied to guard rail lamp of the utility model, including setting exist
The first lens 1 and the second lens 2 of road surface two sides, each lens respectively include bottom plate 3, driving light distribution surface 4 and vertical light distribution again
Face 5, light distribution surface of driving a vehicle and vertical light distribution face are separately positioned on bottom plate, and the polarisation for light distribution surface of driving a vehicle is with light direction and road surface direction
Unanimously, the polarisation in vertical light distribution face is vertical with road center line direction with light direction, and the driving of the first lens and the second lens is matched
Smooth surface is symmetrical relative to the center vertical plane on road surface, and center of the vertical light distribution face of the first lens and the second lens relative to road surface
Vertical plane is symmetrical；The polarisation of first lens and the second lens is consistent with the direct motion direction of vehicle with light direction, and light distribution surface of driving a vehicle is matched
Light curve maximum value is direction of traffic.
Driving light distribution surface is convexed to form by the mirror surface of each lens towards road surface side, and vertical light distribution face deviates from road by each lens
The mirror surface of face side is recessed to be formed；The LED lamp bead of guard rail lamp is correspondingly arranged in the recess in vertical light distribution face.
Side setting of the bottom plate away from road surface positions fixed column 6, to ensure that each lens are relative to LED lamp bead in use
Fixation position it is relatively fixed, to ensure that illuminating effect.
The curvature mirror that light distribution surface of driving a vehicle corresponds to vehicle direct motion direction is less than the curvature mirror in the retrograde direction of vehicle, vertically
The curvature mirror of light distribution surface upper end is less than the curvature mirror of lower end.To enable the first lens and the second lens to match by driving
The light of LED lamp bead is deflected along vehicle direct motion direction and is emitted by smooth surface, while increases the elevation angle of lamps and lanterns by vertical light distribution face,
More light are mapped among road.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation, it is any however, be not intended to limit the utility model although the utility model has been described by way of example and in terms of the preferred embodiments
Those skilled in the art are not departing within the scope of technical solutions of the utility model, certainly can be using in the technology disclosed
Appearance makes a little change or modification, becomes the equivalent embodiment of equivalent variations, but all without departing from technical solutions of the utility model
