Description
Technical field
The present invention relates to LED white-light illuminating field, specifically a kind of LED street lamp lighting apparatus component.
Background technology
Characteristics such as LED-based long-life, high efficiency, light utilization height, high-power LED illumination now is used widely in road lighting, a lot of people to LED the application in road lighting done a lot of trials, but be not difficult to find out this over 1 year the LED street lamp well do not developed, tracing it to its cause is: cost height, life-span are short, illuminating effect poor (lack of homogeneity).The upstream industry development is rapid fortunately, and the lifting of led chip light efficiency and the reduction of price all make the LED road lighting more and more nearer, and the optical design of specialty also makes illuminating effect that very big lifting is arranged, and also has more producer doing such trial.But the how simple employing reflective surface of present LED street lamp carries out Design for optical system in conjunction with LED module placement direction, this method for designing is difficult to the road surface uniformity that reaches satisfied, and can cause the waste of a lot of light, the configuration design of light fixture simultaneously has been subjected to very big restriction.And common secondary optical lens material is PMMA, and the transmissivity of the PMMA material that present technology is used has only 94%, is made into behind the lens because the effect of turning back and penetrating has more additional light loss usually.
Summary of the invention
Technical assignment of the present invention is at above-mentioned the deficiencies in the prior art, and the LED that a kind of cost is low, optical efficiency is high is provided street lamp lighting apparatus component.
LED street lamp lighting apparatus component of the present invention comprises LED, reflective device, ray machine framework and heat radiation entity, carries out reflective and luminous intensity distribution by the reflective device of reverberation bowl formula, reach higher light efficiency and form rectangular light spot,
Described reflective device is the reflective device of reverberation bowl formula, its light-emitting window is rectangular bamboo basket shape light-emitting window, its reflecting surface is made up of three parts, intermediate host partly is the parabolic refractive body of water tank type, two is the same focal length, with the parabolic refractive body of even depth, the focal length of two refractive body, the degree of depth are consistent with focal length, the degree of depth of the parabolic refractive body of intermediate host part water tank type;
Reflective device bottom is provided with the LED putting hole;
Parallelly on the described ray machine framework be provided with three and fall dovetail grooves, the inclination angle of the cross section of falling dovetail groove dual-side is 45 °;
The side of falling the dovetail groove by aluminium base and ray machine framework after reflective device combines with LED fixes.
In order to make LED after the light through reflective device internal reflection surface changes, can form similar rectangular light spot at light-emitting window, so that realize the suitable distribution curve flux of whole street lamp, can make the focus of the parabolic refractive body of reflector spare intermediate host part water tank type and the focus of two refractive body, with placement LED luminous position point in the same space position.That is, make the LED light-emitting area be in the focal position of whole reflective device.
Preferably, the parabolic refractive body at reflective device two formed by excessive cooperation of two free form surfaces, and free form surface physical distance intermediate host water tank type parabolic refractive body centre distance in both sides is 5.5mm.
Preferably, can establish reflector efficiency at reflective device inner surface and be not less than 96% reflectance coating.As the composite reflectance coating: Al_2O_3/MgF_2 reflectance coating, silver-plated reflectance coating: reflectivity reaches＞and 98.5%; KIMOTO reflectance coating and Dong Li reflectance coating or the like.
LED street lamp lighting apparatus component of the present invention compared with prior art has following outstanding beneficial effect:
(1) adopt the reflective device of reverberation bowl formula to carry out reflective and luminous intensity distribution, the efficient height, use common Lambertian to go out the led light source of optical mode, single light source can reach the hot spot effect of desirable roads light, therefore can be according to street lamp power needs increase and decrease LED quantity;
(2) through simulating, too part light can be accessed, the light distribution requirements of roads light can be satisfied in a lateral direction along the road surface;
(3) compare with general high-power LED street lamp secondary lens optics luminous intensity distribution, have characteristics such as cost is low, optical efficiency is high, assembling is easy.
