Description
Technical field
The utility model relates to technology and the design of LED lamp post structure of adopting LED to carry out road lighting.
Background technology
LED (light emitting diode) is because energy consumption is low, and the life-span is long, in recent years by extensive exemplary application in road lighting, it is 3000 multinomial that the patent application that only relates to the LED street lamp in China has surpassed.National government has been released the test plan in " ten thousand in ten cities " for the LED illumination that promotes development from 2008, encourage each manufacturing enterprise, research and development unit exploitation road lighting lamp.
Because single LED luminescence chip power is very low, but road lighting is very big with the power that lamp requires, and all road lamp devices all require a plurality of LED aggregate erections within a lamp device.Because the situation of road lighting is special, the light that the designing requirement light fixture of street lamp sends can be concentrated from afar and project in the long and narrow path area, and produces uniform brightness simultaneously.Research through domestic and international numerous designers and technical staff has obtained some achievements in this respect.Disclosed up-to-date typical achievement comprises: China's patent: " patent No. 101118047A ", " high-power invention street lamp patent of invention: CN101487579B " (authorizing in 2002 0602), and the international monopoly of quoting; Patent of invention " CN101649976B (authorizing in 2011 0209) "; Patent of invention " CN 10144589A "; Patent of invention " CN 101059213A ".All these patents all are to attempt to adopt the way of 3 times different luminous intensity distributions to adjust the output light distribution of light fixture, and combine the street lamp mounting means to carry out luminous intensity distribution the 4th time, in the hope of reaching uniform road illumination and the purpose of saving energy consumption.Though the frame mode that adopts is different, and is the same with known other technologies scheme, all be the variation that has utilized LED mounting structure in the light fixture, the arrangement of adjustment LED realizes the photodistributed both wings of bat shape are strengthened with different modes.And then utilize the illumination between adjacent a plurality of street lamps complementary, make road better reach even illumination, and obtain energy-saving effect preferably.
Yet,, also do not have a kind of more satisfactory street lamp design can really satisfy the specific (special) requirements of road lighting all sidedly up to now though hundreds of multi-form product occurred.This be because, adopt LED as road lighting, except energy-conservation, can not ignore the purpose that street lamp is set is the safety traffic that guarantees vehicle, just will make the driver that the better road traveling visual field is arranged.And above mentioned scenarios is directed against is to improve road illumination and save two indexs of energy loss, all be to integrate improvement from the angle of using energy source.The not direct involvement aspect of these performance indications is to numerous drivers' application performance index.So adopt LED street lamp that existing fabrication techniques goes out often than the approval that is easier to obtain administration of energy conservation department, but be difficult to road user and accept.
The user of road mainly is the driver, and the brightness on the just road surface that his vision can be experienced is the brightness on the road surface seen on his the residing steering position more strictly speaking.And his suffered interference also mainly is the minute surface reflection (particularly rainy day) that street lamp is head-on produced according to dazzle that comes and road surface.The illumination on road surface is meant the illumination flux from light fixture that receives at the road surface per unit area, and the brightness on road surface is by the luminous flux of road reflection to observer's eyes position.The brightness on road surface has more than the illumination that depends on the road surface, but relevant with the character state on the incident angle of the illumination on road surface, light, observer, driver's position, road surface.Especially when crevice projection angle differs greatly, the luminance factor on road surface can mutually far short of what is expected times.The street lamp that can produce even road illumination in other words might not produce the road surface brightness of the equilibrium that the driver hopes to see.That takes in the prior art strengthens with sidelight, throws the road scope that obtains even illumination with light source wide-angle distance light, and has reduced trackside light and overflow, and shifts to an earlier date illumination efficiency.But this has increased the inhomogeneities of road surface brightness simultaneously.
The specular light that direct irradiation or the light fixture from light fixture in the angular field of view that drops on the observer produces is depended in the dazzle that street lighting produces on the road surface.The wide-angle sidelight that the reinforcement batswing tab distribution that prior art adopts produces strengthens illumination can be to serious blinding glare or the discomfort glare that shows of human pilot generation.This is the critical defect that existing LED road lighting technology is brought when pursuing the road surface uniform illumination.
In addition, be to adopt angle pencil of ray LED to carry out street lighting in the prior art, because all be (also being the width of road) that the beam angle that will use the LED unit to be produced comes horizontal covering path illumination.And because the output of LED light beam, the Illumination Distribution on its arrival ground mostly is the distribution of bell (optical axis center is high, and periphery is low); The street lamp of prior art; Be installed in the road both sides,, the center line of road illumination be improved even if adopt the suitable elevation angle to install; But the result of common lighting always near the illumination of the road middle body of light beam axis, always will be higher than the road both sides.If make the two sides of road satisfy minimum illumination or brightness requirement, the unnecessary illumination that the street lamp of existing technology will improve at the road mid portion greatly.And this lighting arrangements has a large amount of light and overflows the road surface from the road both sides, causes waste, thereby reduced the road lighting rate of energy.And because the tapered projection of LED light beam distributes, at near-end and far-end, its illumination spoke lid scope is different.Prior art all is to adopt LED unified or that be number several kinds of beam angle broads seldom to throw light in same light fixture.Consequently, if near-end can satisfy the covering on road surface, a large amount of light will take place and overflow in far-end light, and are if the LED beam angle is less, just smaller in the illumination zone of near-end. and in the lower end near LED, this light beam just can not be full of the road surface.Length direction has carried out pterion light intensity branch enhancing even prior art is on the road surface, but can not solve the problem that horizontal proliferation is overflowed.
In addition; Also there is a very serious shortcoming in prior art, is exactly that each technology all is to a certain characteristics or is fit to a certain type of road and designs, and lacks the distribute mobility of adjustment of light on the structure; Same Design of Luminaires can not be fit to different roads.Though what have provides the scope that can supply regulate technically, all be global design on the structure of machinery and electronic driver, can't carry out part adjustment, because in fact remain an a kind of scheme of lamp.And these designs, in case all be that partial LED is damaged, just can only integral replacing.This overall fixed design, different people, different views is intelligent, lets a hundred schools contend, and is difficult to carry out part-subassemble standardization.So the basis of large-scale production of not standardizing, thereby can not be applied on a large scale.
The utility model content
The purpose of the utility model is to provide a kind of LED street lamp of free from glare, to avoid the dazzle that street lamp produces and the minute surface reflected glare of road surface generation as much as possible, makes the driver that the better road traveling visual field can be arranged, thereby has guaranteed the safety traffic of vehicle.
For solving the problems of the technologies described above; The embodiment of the utility model provides a kind of LED street lamp of free from glare; Comprise: the curved lamp housing of top inner wall 1, at least three mechanical structured members 2 that independently are used to install led array, mechanical structured member 2 is installed in said lamp housing 1 inboard;

Fig. 2 is the sketch map that can independently change according to the mechanical structured member in the utility model one preferred embodiments.
The specific embodiment
The utility model one preferred embodiments relates to a kind of LED street lamp of free from glare.As shown in Figure 1, the LED street lamp of this free from glare comprises: by lamp housing 1, at least three independences that are installed in lamp housing 1 inboard and the mechanical structured member 2 that is used to install led array that can change that top inner wall is curved.Mechanical structured member arc inner wall direction along lamp housing in lamp housing is fan-shaped array; The platform 3 to the lower surface of each mechanical structured member for the installation led array; The mounting base of at least one led array 4 is housed on each platform; Form the obtuse angle each other along fan-shaped lower edge between each platform plane and interlock, the emission optical axis that is installed in each led array on each platform forms each other in the projection plane parallel with covering of the fan and intersects.
Wherein, The mounting base of the led array at edge is not less than 40 ° with the vertical normal angle of cut A on the road surface of being thrown light in the lamp housing; And; On perspective plane, have the LED mounting base of two kinds of normal direction Different Plane at least, and the acute angle that these two normals that are in the LED mounting base of Different Plane are crossed as is less than 30 ° on said perspective plane perpendicular to the link length direction.
The beam angle of all led array is all less than 50 °, is in the beam angle of led array that the fan type arranges edge less than 28 °.On the vertical plane parallel with the road surface length direction, the line at the below of light fixture case both sides and the led array center in the outside, limit that is installed in offside, with the normal angle of the crossing B of the mounting base of the led array in this outside, limit less than 20 degree.Each led array by at least 3 independently led chip, the secondary optical system of projection is assembled in output to corresponding LED light, the substrate that LED and said secondary optical system be installed is formed jointly; Led chip in the same led array is installed on the same printed circuit board (PCB), constitutes the common output of direction, and constitutes common optical axis and output beam angle, is connected to driver through common electricity input.
Need to prove; The electronic driver that is used to drive the led array on this mechanical structured member is being housed on each mechanical structured member; This electronic driver is connected to arrangements of electric connection; This arrangements of electric connection is in company with this mechanical structured member on loading onto lamp housing the time, is connected to be arranged in advance in the inner supply socket of lamp housing, with the electronic driver energized.And, in described street lamp, have at least two groups of led array to adopt different power to drive.Because independently being used to install on the mechanical structured member of led array, each is furnished with independently electronic driver, therefore can be according to the requirement of three luminous intensity distributions, with each led array beam angle; Projecting direction, the power output of adjustment array changes the light intensity that its throws; Cooperate the mounting arrangements of street lamp, accurately dispose the power of road surface illumination, the luminous intensity distribution of existing four levels; Thereby it is even to reach road surface brightness, simultaneously is again the purpose of high-light-energy utilization rate.
That is to say,, the identical fan-shaped LED mounting platform (promptly being used to install the mechanical structured member of led array) of a plurality of contour structures has been installed in the inside of the shell (being lamp housing) of a cylindrical shape.Mounting platform is inboard along the lampshade cylinder, and neighboring devices forms domes.Each platform all can independently insert or take out, and is as shown in Figure 2.The end face in the face of the arch-core direction of each platform is provided with 8 pedestals that led array is installed, and each pedestal all has the plane that led array is installed, and between the LED mounting plane of each pedestal and the place platform end face, the angle of setting is arranged all.The light beam projecting direction (or optical axis direction) that is installed in 8 led array on the pedestal has angle to interlace between mutually.A led array all is installed on each pedestal.Led array is to post the metal green sheet of 9 led chips and transparent cover that the top is provided with 9 positions and the corresponding secondary optical system of led chip is formed by unified.Described secondary optical system is the custom-designed collector lens that is arranged on the capping top, and the light that it sends led chip converts the directed projecting beam of certain beam angle to.The luminous power of this array and beam emissions angle are by the optical design decision of LED that is pasted and the capping of selecting for use.Adopt the secondary optics closure design of existing LED product line and prior art, just can make up the led array of multiple performance.Capping self has also risen led chip, together with the close and protect effect of eyeglass inner surface.
Inner at fan-shaped mounting platform, the electronic driver that is used to drive the led array on this platform is housed.The output of electronic driver is wired on the metal green sheet of each led array.The input of electronic driver is connected with connector.This connector is connected with the supply socket that is installed in advance on the lamp housing when the platform plug-in mounting is gone into lamp housing simultaneously.
Be not difficult to find that in this embodiment, through the foundation design on each platform, the led array emitted light beams that a plurality of angles are less constitutes the laterally evenly illumination in a certain length section in road surface, the light that has also reduced the road edge simultaneously overflows.And being assembled into each platform of arch, each that send section illumination complements each other, and constitutes the even illumination of link length aspect.The light fixture case edge of cylinder shape is used to produce photodistributed rescinded angle effect, to guarantee that light fixture can not form dazzle.
This shows that this embodiment uses a plurality of secondary optics Combination Design, particularly adopt the different low-angle led array combination of the angle of departure.For cooperating the led array of multiple projectional angle and beam angle, adopt mechanism identical but settle the different a plurality of led array mounting platforms of angle and the LED electronic driver that divides into groups independently to assist to construct optical design for the third time.The scheme that optical design is for the third time constructed in this multifactorial cooperation is to satisfy various application conditions and specification requirement provides maximum mobility, can realize that the desirable irradiation in complicated cutting back angle distributes.Because the photodistributed light fixture of rescinded angle type, its illumination range is only limited to 2/3rds illumination highway section near the light fixture both sides (that is the highway section between two adjacent lamp stands).Its light radiation is not delivered to far-end, arranges like this that therefore street lamp can not produce dazzle to the vehicle driver.Because the incidence angle excursion that shines on the ground is smaller, and do not have big incidence angle illumination, the index variation difference of road surface brightness all is far smaller than the illuminating street lamp of prior art.Because the rescinded angle illumination light distributes, the angular range of light fixture road pavement irradiation is well-illuminated little more a lot of than existing enhancing bat type street lamp fire.The illuminance uniformity on road surface and brightness uniformity are unified easily to be improved, and for the road surface of one-way traffic, the utility model can be accomplished best brightness uniformity especially.This road lighting is just pursued and is helped and existing technology is difficult to accomplish.The cutting back angle illumination light that adopts the utility model to realize distributes; Can make range estimation person in the visual range of 20 ° or 30 °, all can't see direct light, therefore can reach the free from glare effect of disability glare T1=0 or discomfort glare GR=0 in theory from light fixture.Thereby make the driver that the better road traveling visual field can be arranged under the bright condition of lower low consumption, guarantee the safety traffic of vehicle.
The simplification maintenance of the utility model when the structural uniformity of machine assembly is the standardization of products and use provides maybe.That is to say that this embodiment is a kind ofly can satisfy the combination lamp post structure that the LED road lamp carries out each item index of area illumination comprehensively.It is according to desired vertical and horizontal illumination profile in the field of illumination, the requirement of rescinded angle light, in light fixture low-angle led array category set inside, and be installed to can be mutually can the normal structure of amalgamation on.Utilize the installation direction of standard platform, light is distributed make orientation adjustment, and utilize the power adjustment of the independent electronic driving of each platform, guarantee the accuracy of photodistributed setting, reach the performance target of the illumination functions of optimization comprehensively.Because led array, mounting platform, electronic driver and shell all are relatively independent, and can standardization large-scale production, therefore help the mass-produced standardization of street lamp and apply.Product can adapt to various road conditions and design assembly unit.Separating component is convenient to on-site maintenance maintenance again, change easily worn part and need not carry out integral replacing to street lamp like this to prior art.
In sum, this embodiment provides a kind of limited standard unit combination of using, and just can constitute to satisfy various application conditions and the street lamp product of optimizing effect.Almost the illumination scheme of any calculation optimization all might obtain implementing in this product design.Rather than the illumination Design taked of prior art be subject to light fixture traditional approach.The enforcement power bracket of embodiment on same frame for movement of the utility model technology also can from tens watts to several hectowatts, width of roadway can be from 6 meters-40 meters, the road distance between tie rods is from 20 meters-35 meters; Height is from 5 meters-15 meters, and is one-sided, bilateral; Interlaced arrangement; Various different pavement qualities, all available with a kind of light fixture, suitably select element to make up and be met.Therefore be a kind of desirable, can supply the LED street lamp design of large-scale standardized production and popularization.
Above-mentioned embodiment is a specific embodiment of realizing the utility model, and in practical application, can be in form with on the details it is done various changes, and do not depart from the spirit and the scope of the utility model.
