Description
Technical field
The utility model belongs to lighting technical field, relates to a kind of lighting, is specifically related to a kind of light chopping LED road lamp.
Background technology
The New Times of lighting engineering revolution has been opened up in the development of LED technology, because LED has plurality of advantages such as volume is little, the life-span is long, electrical efficiency is high, environmental protection and energy saving, makes LED street lighting technology obtain developing rapidly in recent years.At present; The reality of single on the market LEDs light source can be accomplished 100lm/W; Adopt tradition 250 watts of LPS street lamps (low-pressure sodium lamp) or MH (metal halide lamp) street lamp; After the led light source replacement, only need 60 plurality of LEDs just can produce identical brightness, thereby greatly saved the consumption of the energy.
Because the radiation angle of most of led light source is distributed as 120 ° to 110 ° lambertian distribution; Impinging upon ground smooth type is that central light strength is stronger; The symmetrical circular hot spot distributes; There is 50% light to be scattering into outside the road approximately and is not utilized, and can produce dazzle, be not inconsistent with the requirement of road lighting to vehicle or pedestrian at a distance.Led light source is made up of the led chip and the lens of this chip of sealing at present; " city illumination design standard " requires the luminous intensity distribution of street lamp is rectangle, equally distributed hot spot, therefore needs on led light source, to install an optical lens reasonable in design, but because some LED Design of Luminaires are unreasonable; Cause the optically focused performance not high enough; Can't light field be accomplished the distribution of degression type, form irregular luminously, thereby use to road lighting and to have caused inconvenience.
The utility model content
The purpose of the utility model is to overcome above-mentioned deficiency of the prior art, and a kind of light chopping LED road lamp is provided, and it is reasonable in design, and is simple in structure, good illumination effect, and efficiency of energy utilization is high, and operating cost is low, is convenient to promote the use of.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: a kind of light chopping LED road lamp; It is characterized in that: comprise radiator and led light source, said radiator upside is provided with the optical lens with convex lens characteristic, and said optical lens set inside has led light source and heat transfer substrate; Said led light source is fixed on the heat transfer substrate, and said heat transfer substrate is fixed on the radiator.
Said optical lens is installed on the radiator through feet.
Said optical lens incident tangent plane to a surface becomes with horizontal plane greater than 30 ° and less than 60 ° inclination angle.
The utility model compared with prior art has the following advantages:
(1) this light chopping LED road lamp is reasonable in design; Its optical lens incident tangent plane to a surface becomes with horizontal plane greater than 30 ° and less than 60 ° inclination angle; The light that makes led light source emit can be regulated optical field distribution by far and near distance, and realizes cutting light at lens plane of incidence edge, collects the edge veiling glare; Thereby eliminated dazzle, illuminating effect is very good.
(2) this light chopping LED road lamp is compared with conventional low sodium street lamp or metal halide street lamp, has improved utilization rate of electrical greatly.
(3) production cost of this light chopping LED road lamp and operating cost are all very low, are convenient to promote the use of.
Through accompanying drawing and embodiment, the utility model is done further detailed description below.

Description of reference numerals:
The 1-radiator; The 2-heat transfer substrate; The 3-LED light source;
The 4-optical lens; The 5-feet.
The specific embodiment
A kind of light chopping LED road lamp as shown in Figure 1; Comprise radiator 1 and led light source 3; Said radiator 1 upside is provided with the optical lens 4 with convex lens characteristic; Said optical lens 4 set inside have led light source 3 and heat transfer substrate 2, and said led light source 3 is fixed on the heat transfer substrate 2, and said heat transfer substrate 2 is fixed on the radiator 1.
As shown in Figure 1, the aluminium base of said heat transfer substrate 2 for having the good heat transfer rate, aluminium base not only heat transfer property is good, also has advantages such as the processing of being prone to, cost are low, non-corrosive.
As shown in Figure 1, said optical lens 4 is installed on the radiator 1 through feet 5.
As shown in Figure 1; Said optical lens 4 incident tangents plane to a surface become with horizontal plane greater than 30 ° and less than 60 ° inclination angle; The light that the inclination angle makes led light source 3 emit can be regulated optical field distribution by far and near distance, and realizes cutting light at lens plane of incidence edge, collects the edge veiling glare; Thereby eliminated dazzle, played good illuminating effect.
The course of work of the utility model light chopping LED road lamp is: at first this light chopping LED road lamp is installed on the street lamp post, and energized, led light source 3 can be luminous; LED light is through behind the optical lens 4; Have good optical field distribution, and realize cutting light, collect the edge veiling glare at lens plane of incidence edge; Thereby eliminated dazzle, played good illuminating effect.The heat that produces when led light source 3 is luminous in addition can conduct on the radiator 1 through aluminum heat transfer substrate 2 fast, and heat is left very soon.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any restriction; Every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of the utility model technical scheme.
