Abstract
The utility model relates to the non-imaging optical technology of LED lighting, in particular to an integrated LED street lamp light distribution lens. The integrated LED street lamp light distribution lens comprises a lens body, and is characterized in that a plurality of light spots combined in different manners are arranged on the lens, and distribute lights which are emitted by an LED and accords with the Lambertian distribution into bulb-shaped light spots in the road length direction; if a light distribution curved surface of the lens is in the direction of a road and passes an optical axis, an included angle between an edge light of the lens and the optical axis is Phi, wherein Phi is larger than or equal to 30 degrees; if the light distribution curved surface of the lens is in the direction of the road and passes the section of optical axis, an included angle between light with the largest emergence angle and the optical axis is Omega, wherein Omega is larger than 60 degrees and smaller than 70 degrees. The light efficiency of the integrated lens is 96%, and is higher than 3%-5% of that of a traditional lens, so that the lighting effect of an LED street lamp is greatly improved.
Description
Technical field
The utility model relates to the nonimaging optics technology of LED illumination, more particularly, relates to a kind of integrated light-distribution lens for LED street lamp.
Background technology
LED(Light Emitting Diode, light emitting diode) New Times of lighting engineering has been opened up in the development of technology.Because LED has the plurality of advantages such as the life-span is long, and light efficiency is high, and volume is little, and electrical efficiency is high, environmental protection and energy saving, make LED street lighting technology at high speed development recent years.Because most of LED street lamp radiation angles are distributed as the lambertian distribution (Lambertian distribution) of 110 degree to 120 degree, if the light type not impinging upon on road surface through luminous intensity distribution is the circular hot spot that disperses, approximately 50% light falls apart and is not utilized to road outside, and can produce dazzle to vehicles or pedestrians at a distance, be not inconsistent with the requirement of road lighting, it is rectangular hot spot that good road lighting requires the luminous intensity distribution of street lamp, and nearly all light all can be distributed on road surface.
In addition, on some trunk roads, because street lamp mounting distance is distant, if lamp is apart from 50 meters or 60 meters, existing street lamp is difficult to road surface between two street lamps to carry out adequate illumination.
Tradition LED lens are single arrangement, in lamp assembled and structural design, waterproofing design, expend more materials and need more complicated packaging technology.
Summary of the invention
The purpose of this utility model is to solve between street lamp in the larger situation of spacing, and road surface can not adequate illumination, and LED street lamp light utilization is low, single the problem that installation process wastes time and energy.
The present invention is in order to solve the problems of the technologies described above, the technical scheme of taking is: for the integrated light-distribution lens of LED street lamp, comprise lens body, it is characterized in that: on lens, be provided with the hot spot of several various combination, the light of the lambertian distribution that this hot spot sends led is made into the ball bubble shape hot spot along link length direction; The light distribution curved surface of lens is along road direction and by optical axis, the angle of the rim ray of lens and described optical axis is φ, φ >=30 °; The light distribution curved surface of lens is along road width direction and by the cross section of optical axis, and the angle of the light of angle of emergence maximum and described optical axis is, ω, 75 ° of 60 ° of < ω <.
Described lens are provided with external diameter and internal diameter, and external diameter is reserved with capillary groove, and sealing ring is arranged in this capillary groove; Inner radius is also provided with groove, in this groove, is placed with sealing ring.
The number of combinations of described hot spot is 3.
Described φ is 32 °.
Described ω is 70 °.
The invention has the advantages that: after adopting integrated lens, simplify and strengthened waterproofing design, owing to having reduced the design (for waterproof and dustproof) of the saturating safety glass of existing height, make light source light transmission efficiency of the present invention and distribution curve flux precision all there is great raising.
?owing to adopting 3 kinds of different distribution curve fluxs in structure, realize the whole luminance effects that improves light, and the illumination range of light.
?in order can be thrown light on fully in the region between two lamps, need to adopt light constraint full-shape is the light-distribution lens of 135-145 °, and integrated light-distribution lens has increased the road surface illuminance between street lamp, makes road lighting become very even.
The reserved groove of lens internal diameter external diameter is can add sealing ring in order to install, and realizes waterproof effect.
In brief, integrated lens luminous efficiency is 96%, than traditional high 3%-5% of lens luminous efficiency.Greatly strengthened the light efficiency of LED street lamp.
