Description
Technical field
The present invention relates to a kind of LED street lamp, relate in particular to high-power, high brightness LED (LED) street lamp as the shaft-like profile of lighting source, and other outdoor lighting light fixture, as Lawn lamp, garden lamp, road sign indicator lights, belong to technical field of semiconductor illumination.
Background technology
Since Edison's invention electric light in 1882, artificial lighting source has experienced incandescent lamp, fluorescent lamp and gas-discharge lamp three phases.At present at indoor a large amount of use fluorescent lights, at outdoor then a large amount of using gases discharge lamps, luminous principle was made when gas-discharge lamp utilized electric current by gas in the lamp or steam, need the rectifier build-up of luminance, the building-out capacitor that needs in service, to improve power factor, according to the requirement of road actual illumination, the street lighting light source adopts high-pressure sodium lamp, low-pressure sodium lamp or high-pressure mercury lamp usually.These light sources have the light efficiency height, and are photochromic good, the characteristics that the life-span is long.Weak point is: the light colour rendering is poor, lights to start slowly, and power factor is low.The high-pressure sodium lamp light source contains poisonous mercury in addition, can cause certain harm to environment.
In recent years, along with the continuous development of LED scientific research and the chip technology level of production constantly promote, the high-power LED encapsulation technology is ripe gradually, and the LED luminous efficiency is greatly improved, and its application is progressively widened.LED is the less semiconductor devices of a kind of appearance and size, plurality of advantages such as have that size is little, life-span length, vibration resistance, no mercury are nontoxic, no electromagnetic pollution, no harm ray, luminous efficiency height, initial drive characteristic are good, reliable operation, Maintenance and Repair workload are low especially.The laboratory light efficiency index of 1W white light LEDs product has surpassed 1001m/W at present, progress of science and technology makes LED very likely become general solid light source of new generation, is also progressively using the lighting source as outdoor street lamp, Lawn lamp, garden lamp, trail guide.
LED is a kind of cold light source, and its principle of luminosity is the compound photon that directly sends of electronics process, does not need the process of heat, and still, the efficient of LED when transferring electric energy to luminous energy is not to be 100%, can follow heat to produce in luminous yet, and take care of the pence.If heat can not get fully distributing, the LED internals will produce mechanical stress because of thermal coefficient of expansion is different, and this stress can cause the LED fault.Junction temperature rising LED luminous efficiency can sharply descend, and too high temperature also can shorten even terminate service life of LED.
According to national city illumination design standard regulation, requiring the mean flow rate of illumination on through street is 1.5nit (Cd/m
2), illumination is 20 (Lx); Trunk roads and secondary distributor road require the then corresponding reduction with illumination of mean flow rate of illumination, and the mean flow rate of mainly throwing light on for the current rto request of pedestrian and non motorized vehicle approximately is 0.1nit (Cd/m
2), illumination is 1～2 (Lx).This shows that the brightness of the street lamp that uses is corresponding will to reach thousands of to tens thousand of lumens on main arterial traffic.With high-power, high brightness LED (LED) street lamp as lighting source, so high brightness is provided, need the integrated application of a plurality of LED large-power light-emitting diodes.Therefore, the structural design of road lamp system and heat dissipation technology research are the important technological problems that must consider.
Summary of the invention
The purpose of this invention is to provide a kind of with high-power, high brightness LED (LED) LED street lamp as lighting source.
For realizing above purpose, technical scheme of the present invention provides a kind of Novel LED street lamp, comprise the high bar of street lamp, street lighting light source assembly and power conversion and control module and main strut, be provided with branch pole and main strut in the high bar of street lamp upper end, be respectively equipped with the street lighting light source assembly in the end of minute pole and main strut, it is characterized in that, position in the bottom of the high bar of street lamp near ground is provided with power conversion and control module, the one side is provided with air inlet, is provided with motor at street lighting light source assembly one end.
The high bar of described street lamp, branch pole and main strut are hollow, at main strut and branch pole the airflow line that area of section is gradual change from fine to coarse from top to bottom are set.
That the present invention adopts is high-power, high brightness LED (LED) is as the street lamp of lighting source, and the high bar of street lamp, mobile jib and branch pole inner hollow are to guarantee the air up/down perforation.Because stock and pressure differential effect, the inside of high bar can produce the higher air-flow of flow velocity, the high bar of street lamp has more than one air inlet near the suitable position on ground, utilize the air of the inner high speed convection that produces of middle outage bar of street lamp, for the lighting source of street lamp high-power, high brightness LED (LED) assembly provides heat radiation, temperature rise control certain numerical value when making light emitting diode work, prevent that the rising of LED junction temperature from causing the rapid decline phenomenon of luminous efficiency, improve the heat radiation of lighting source LED assembly, guarantee the safe operation of LED street lighting light source and the service life of expection.
Advantage of the present invention is rational in infrastructure, and is convenient for installation and maintenance, and energy-saving effect is remarkable, is a kind of Green Product, is fit to all kinds of road lightings.
