Abstract
The utility model discloses a polarized lens of an LED street lamp, which comprises a lens body, wherein a sphere-like inner cavity is arranged on the bottom plane of the lens body and used for holding an LED bulb and forms the incident light surface of the lens; the plane opposite to the bottom plane where the incident light surface is positioned adopts an emergent light surface; and a warp is arranged at one side edge of the lens body and used for reflecting the light emitted from the incident light surface. The polarized lens is applied in the LED street lamp so as to effectively project the light onto the motor vehicle lane and eliminate the need of adjusting the elevation/depression angle of the street lamp, is very convenient to use, and effectively solves the problems of inconvenient adjustment and light pollution of the prior art.
Description
Technical field
The utility model relates to a kind of lens, especially a kind of spreadlight lens with the LED street lamp.
Background technology
Street lamp is the important component part of road lighting, traditional street lamp often adopts high-pressure mercury lamp, the high-pressure mercury lamp shortcoming that light efficiency is low has on the whole caused the huge waste of the energy, therefore, the LED street lamp as a kind of new and effective, energy-conservation, the life-span is long, colour rendering index is high, the street lamp of environmental protection and being widely used in the city illumination engineering.In the practical application of LED street lamp, people often need install a secondary lens again in order to obtain suitable distribution of light and illumination brightness on LED lamp pearl.Yet, being limited to the structure of secondary lens in the prior art, the light that LED lamp pearl sends has the light of quite a few to project on the pavement through perpendicular projection.This has not only dwindled the motor road illumination zone, has also reduced the uniformity of car lane illumination, influences traffic safety easily.Traditional solution is to adjust the light fixture elevation angle, but this method then can cause inconvenience is installed, and influences attractive in appearance.And this lens also can cause certain light pollution.
The utility model content
For addressing the above problem, the utility model provides a kind of light chopping lens that can concentrate projection LED lamp pearly-lustre line.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of LED street lamp spreadlight lens, comprise lens body, described lens body base plane is provided with the class spherical inner chamber of putting into for LED lamp pearl, it forms the incidence surface of lens, the reverse side of the base plane at described incidence surface place is an exiting surface, and a lateral edges of described lens body is provided with the warpage that light that incidence surface is penetrated reflects.
As improvement of the technical scheme, a side that is positioned at warpage in the described class spherical inner chamber be provided with relative with warpage and with base plane vertical substantially go into optical plane.
As further improvement in the technical proposal, described warpage is formed by the spherical arc transition of plurality of sections different curvature or same curvature.
As further improvement in the technical proposal, the both sides relative with going into optical plane are provided with the groove that is used for cutting light on the described lens body.
As further improvement in the technical proposal, also be provided with mounting structure on the described lens body.
As further improvement in the technical proposal, described mounting structure is the alignment pin that is symmetricly set on the lens body side.
The beneficial effects of the utility model: when the light that sends when led light source is refracted to lens warpage position by spreadlight lens class spherical inner chamber incidence surface of the present utility model, make the light generation total reflection that projects the lens afterbody, effect thereby realization light does not reflect the lens afterbody in whole reflected back lens, the light of reflected back lens throws away by exiting surface again, can form specific light spot shape towards a side of lens exiting surface.Can be effectively in the LED street lamp application with ray cast to car lane, thereby do not need to adjust the angle of pitch of street lamp, use very conveniently, can effectively solve lens exist in the prior art adjustment inconvenience, have the defective of light pollution.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a perspective view of the present utility model;
Fig. 2 is that the utility model lens are looked up structural representation;
Fig. 3 is the utility model lens perspective structure schematic diagram.
The specific embodiment
Referring to figs. 1 through Fig. 3, a kind of LED street lamp spreadlight lens of the present utility model, comprise lens body 1, described lens body 1 base plane 11 is provided with the class spherical inner chamber of putting into for LED lamp pearl 2, it forms the incidence surface of lens, the reverse side of the base plane 11 at described incidence surface place is an exiting surface 3, and a lateral edges of described lens body 1 is provided with the warpage 4 that light that incidence surface is penetrated reflects.When the light that sends when led light source is refracted to lens warpage 4 positions by spreadlight lens class spherical inner chamber 2 incidence surfaces of the present utility model, make the light generation total reflection that projects the lens afterbody, effect thereby realization light does not reflect the lens afterbody in whole reflected back lens, the light of reflected back lens throws away by exiting surface again, can form specific light spot shape towards a side of lens exiting surface.Can be effectively in the LED street lamp application with ray cast to car lane, thereby do not need to adjust the angle of pitch of street lamp, use very conveniently, can effectively solve lens exist in the prior art adjustment inconvenience, have the defective of light pollution.
As preferably, a side that is positioned at warpage 4 in the described class spherical inner chamber 2 be provided with relative with warpage 4 and with base plane 11 vertical substantially go into optical plane 21.Like this, go into optical plane 21 and can light refraction be arrived warpage 4 positions, more rays can be reflected than what concentrate.
Wherein, bright dipping aspect according to actual needs, the angle between warpage 4 and the lens base plane 11 can be adjusted.If warpage 4 is divided into upper and lower surface, then the lower surface of warpage 4 belongs to optical cross section (light only reflects in this optical cross section), this optical cross section is determined according to incidence surface, can with base plane 11 angled being obliquely installed, thereby reach the utility model with the purpose of ray cast to the car lane.Warpage 4 upper surfaces then belong to exiting surface (light mainly reflects at this face), the exiting surface of warpage 4 is to determine according to the optical range that goes out of optical cross section and actual needs, so the actual angle of warpage 4 can design and adjust according to the optical range that goes out of incidence surface and actual needs.
In order to reach different light distribution effects, as preferably, described warpage 4 is formed by the spherical arc transition of plurality of sections different curvature or same curvature.
In addition, in order to reach the purpose of cutting light, both sides relative with going into optical plane 21 on the described lens body 1 are provided with groove 5.
As preferred implementation, can on lens body 1, mounting structure be set, be installed in the street lamp lamp bracket with convenient spreadlight lens this product.Further, described mounting structure is the alignment pin 12 that is symmetricly set on lens body 1 side, and structure is very simple, is convenient to make.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
