Description
Technical field
The utility model relates to a kind of high-power LED street lamp, particularly a kind of failure judgement rapidly, the modular construction high-power LED street lamp that is convenient for changing led light source, is convenient to keep in repair.
Technical background
1, traditional high-power LED street lamp lamp body structure generally adopts the aluminium alloy integral die-cast.The heat radiation of LED street lamp mostly is the heat-conducting plate mode, is the thick copper coin of a slice 5mm, in fact is temperature-uniforming plate, and the thermal source samming is fallen; Also have finned to dispel the heat, but weight is too big.Weight is very important on road lamp system, because the street lamp height has 9 meters, if too heavy danger just increases, especially runs into typhoon, earthquake and all may produce accident.
The radiating mode of tradition high-power LED street lamp mainly is a Natural Heat Convection, rises by hot-air, and light fixture below cold air replenishes, and forms convection current, and the heat of derivation can be distributed rapidly step by step, improves radiating efficiency.And existing the radiating fin area arbitrarily to set in the design of LED road lamp cooling, arrangement is unreasonable, does not consider the occupation mode of light fixture, has influence on the performance of fin effect, only emphasizes heat conduction link, ignores the heat loss through convection link, ignores the harmony of conducting heat.Although numerous producers has considered various measures: heat pipe, loop heat pipe, add heat-conducting silicone grease or the like, do not recognize that but heat finally still will rely on the external surface area of light fixture to loose, if the Temperature Distribution of fin is seriously inhomogeneous, will causing wherein, the fin of a part does not play a role or acts on very limited.
In addition, lamp housing fin radiating mode commonly used now is limited because of surface area, effect still is unsatisfactory, especially the street lamp major part is mounted in highway both sides and outdoor, dust is bigger, in case the heavy collection of dust will reduce radiating effect greatly on fin, shorten high-power LED street lamp service life.
2, generally to adopt the great power LED of single or the integrated encapsulation of multicore sheet be light source to traditional high-power LED street lamp light source, and two kinds of light sources of multipoint mode and integrated form are arranged.The advantage of integrated LED road-light light-source is rectangular light spot, light can evenly cover whole road surface, and shortcoming is that heat radiation is required than higher, and the power concentration of last hectowatt can be brought a large amount of heats on individual chip module, when special LED luminous efficiency was relatively lower, more electric energy had changed into heat energy; The advantage of multipoint mode is that heat radiation is easy, but the circuit structure relative complex, the road surface distribution of light is even inadequately, and the light of multiple spot chip overlaps to form " ghost " phenomenon, the harm traffic safety.
3, the luminous intensity distribution of traditional high-power LED street lamp generally adopts lens to solve, by optical design, according to different needs, be equipped with different convex surface curves, rely on lens that light is assigned to different directions, production technology and raw material enlarge lighting angle, if can not guarantee that it is consistent that lamp light distribution characteristic of the same race just can not reach.Light transmittance is had a greatly reduced quality.
4, the general employing of traditional driving power supply for high-power LED street lamp is street lamp of a constant current switch power supply control, voltage range is generally between 80V-265V, and domestic street lamp voltage at night the highest value range considerably beyond it, can't use once driving power damages street lamp.
This shows, there are many deficiencies in design in traditional high-power LED street lamp: the one, and the heat spreader structures design is lack of standardization, the 2nd, illuminating source packaging structure is unreasonable, the 3rd, the production technology of light-distribution lens and raw material can't guarantee light efficiency, the 4th, the driving power unstable properties, the 5th, produce, install, safeguard more complicated.
Maximum high-pressure mercury lamp of road surface employing now, inner parts such as ballast are not easy to damage, and the reason that major part does not work is that light source damages, and as long as the mode of maintenance is the replacing light source.A skilled operator can the individual carry out high platform operation fully.But, the LED street lamp, inner parts are a lot, damage except other various piece of light source (chip) all to cause chip not work.So can't conclude the reason that the LED street lamp damages at the scene at once.If the LED street lamp does not work, need take the LED street lamp and transport factory back and carry out every detection maintenance, the mode of changing the LED street lamp like this seems very loaded down with trivial details, high-power LED street lamp finally can be selected modularization production, installation and maintenance, make a skilled workman also can independently judge the reason and the device of damage rapidly fully, and carry out field maintenance.
Summary of the invention
Deficiency in view of present high-power LED street lamp existence, order of the present utility model is the high-power LED street lamp of a kind of modular organization of design, make heat spreader module, light source module, power module all can be arbitrarily made with the product of different capacity and brightness demand, its simple modularization composite structure can be convenient to the service worker accurately failure judgement promptly on-the-spot easily repair and replacement of existing side by side rapidly.
