Abstract
The utility model discloses a kind of polarisation road and bridge lens, a kind of polarisation road and bridge lens, including lens body, the lens body bottom surface is equipped with the spherical inner cavity being put into for LED lamp bead, the contact surface of spherical inner cavity and lens body is incidence surface, and the another side of the bottom surface where the incidence surface is the light-emitting surface that the light projected to incidence surface is reflected.When the light of LED light source enters light-emitting surface by spherical inner cavity surface, it is reflected away again by light-emitting surface, effectively light can be projected on road in LED street lamp application, width is projected up to 8 meters, hot spot is uniform, intensity transition is soft, euphorosia, structure is simple, and design is rationally, practical.
Description
Technical field
The utility model relates to lens art, especially a kind of polarisation road and bridge lens.
Background technique
Street lamp is the important component of road lighting, and traditional street lamp is frequently with high-pressure sodium lamp, and high-pressure sodium lamp is on the whole
The low disadvantage of light efficiency causes the huge waste of the energy, and therefore, LED street lamp is new and effective, energy saving as one kind, the service life is long, aobvious
Colour index is high, environmental protection street lamp and be widely used in city illumination engineering.In the practical application of LED street lamp, Ren Menwei
Light distribution and illumination brightness appropriate are obtained, generally requires a secondary lens are installed again in LED lamp bead.However, limit
In the structure of secondary lens in the prior art, the light that LED lamp bead issues passes through perpendicular projection, there is significant component of light projection
Onto pavement.This not only reduces motor road illumination zone, also reduces the uniformity of car lane illumination, is easy shadow
Ring traffic safety.
Utility model content
In order to solve the above technical problems, the purpose of the utility model is to provide a kind of polarisation road and bridge lens.
The technical solution adopted in the utility model is:
A kind of polarisation road and bridge lens, including lens body, the lens body bottom surface are equipped with the class being put into for LED lamp bead
The contact surface of spherical inner chamber, spherical inner cavity and lens body is incidence surface, the another side of the bottom surface where the incidence surface
It is the light-emitting surface that the light projected to incidence surface is reflected.
The lens body bottom surface and side surface are provided with light-blocking lines.
The side of the light-emitting surface is provided with the protrusion that the light for projecting light-emitting surface reflects.
The lens body bottom surface is symmetrically arranged with positioning column.
The light-emitting surface is optical aspherical surface.
The utility model has the beneficial effects that
The utility model is equipped with the spherical inner cavity that is put into for LED lamp bead in lens body bottom surface, spherical inner cavity with
The contact surface of lens body be incidence surface, the another side of the bottom surface where the incidence surface be to incidence surface project light into
The light-emitting surface of row refraction.When the light of LED light source enters light-emitting surface by spherical inner cavity surface, then reflected by light-emitting surface
Go, can effectively be projected light on road in LED street lamp application, projection width up to 8 meters, hot spot uniformly, light intensity
Transition is soft, euphorosia, and structure is simple, and design is rationally, practical.
Detailed description of the invention
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.
Fig. 1 is the stereoscopic figure of the utility model.
Fig. 2 is the utility model front view.
Fig. 3 is the top view of the utility model.
Fig. 4 is the cross-sectional view of the utility model line A-A along Fig. 3.
Specific embodiment
As Figure 1-Figure 4, a kind of polarisation road and bridge lens, including lens body 1,1 bottom surface of lens body are equipped with
For the spherical inner cavity 2 that LED lamp bead is put into, the contact surface of spherical inner cavity 2 and lens body 1 is incidence surface 3, the incidence surface
The another side of bottom surface where 3 is the light-emitting surface 4 that the light projected to incidence surface 3 is reflected.When the light of LED light source passes through
Spherical 2 face of inner cavity enters light-emitting surface 4, then reflect away by light-emitting surface 4, in LED street lamp is applied can effectively by
Light projects on road, projects width up to 8 meters, and hot spot is uniform, intensity transition is soft, euphorosia, and structure is simple, design
Rationally, practical.
1 bottom surface of lens body and side surface are provided with light-blocking lines 5, for preventing the light of LED light source
Leakage, causes the waste of light.
The side of the light-emitting surface 4 is provided with the protrusion 6 that the light for projecting light-emitting surface 4 reflects, and has small
The light that part light-emitting surface 4 projects can be towards the direction of deviating road, which can be totally reflected above-mentioned light, changes
Become above-mentioned light goes out light path so that above-mentioned light, so that light be made more to concentrate, can also add towards the transmitting of the direction of road
The projection width of long light.
1 bottom surface of lens body is symmetrically arranged with positioning column 7, to facilitate the spreadlight lens by this product to be installed to road
In lamp lamp bracket, and positioning is carried out, make bottom surface and road at an angle, usually 30 ° or so, actual angle can be according to entering
Smooth surface 3 and it is actually required go out optical range design and adjust.
The light-emitting surface 4 is optical aspherical surface, and plastic aspherical element optical element is due to, optics low with light weight and cost
Part and installing component can be molded as an entirety the advantages that save assembly work amount and good impact resistance.
The foregoing is merely the preferred embodiments of the utility model, the utility model is not limited to above-mentioned embodiment party
Formula, if with essentially identical means realize the utility model aim technical solution belong to the protection scope of the utility model it
It is interior.
