Abstract
The invention relates to a high-power solid road lamp and aims to solve the problem of heat dissipation in prior art. The road lamp mainly comprises a main housing, a lamp shade, a LED lamp, an external radiator, and a LED power supply unit. The external radiator formed by the heat pipe network can rapidly remove the heat produced during the operation of the ultra-high power LED as well as the heat produced by the power supply unit, so as to ensure the low working temperature of the ultra-high power LED lamp and the power supply unit. As a result, the working temperature of the whole ultra-high power LED road lamp is significantly reduced, the service life of the LED lamp is prolonged, the technical problem of heat dissipation of high-power LED lamp is solved, and the industrialized production and application of ultrahigh power LED road lamps are realized.
Description
Technical field
The present invention relates to a kind of LED lamp, particularly a kind of ultra-high power LED street lamp.
Background technology
At present, worldwide energy shortage has caused the great attention of various countries to power-saving technology, is developing energetically such as solar energy, and in the time of renewable and clean energy resources such as wind energy, various countries also utilize in rational and effective and strengthened dynamics aspect the energy.Being reflected in the illumination aspect is exactly constantly weeding out the old and bring forth the new and extensive use of various new light sources.This wherein, long and its high reliability has caused concern more and more widely and progressively has been applied to lighting field light emitting diode with its low energy consumption, high light efficiency, life-span.Because LED need be below 80 degrees centigrade, the reliable operate as normal of ability.But its in great power LED when work, caloric value was very big moment, therefore how to solve the focus that the great power LED cooling problem has become the solid-state illumination field, and the light decay that great power LED does not freely cause because of heat radiation has also become one bottleneck on the solid-state illumination road.Because the technical problem of heat radiation, the power of the LED of prior art is difficult to do greatly, and chip power is general all below 5W; After our company is solving heat dissipation problem, implement in 2007100031036.6 and 20071003103.0 the Patent project technology of oneself, finding again has the LED supply unit of skill owing to be mounted in the light fixture, temperature is higher in the light fixture, make that fin in the supply unit temperature difference extraneous with it is too little or do not have temperature difference state, in use its fin radiating effect is bad or do not had the effect of natural air cooled heat radiation, has occurred satisfying the problem that operate as normal requires.
Summary of the invention
The objective of the invention is to design a kind of large power solid-state illumination street light fitting scheme and products thereof at a present high-power LED lamp heat dissipation technology difficult problem.
Large power solid-state illumination street light fitting of the present invention, comprise light fitting main casing, lampshade, the LED lamp, external radiator, LED supply unit critical pieces such as (or claiming LED power circuit system device) constitutes, its light fitting main casing is provided with and comprises housing, the heat pipe connector, the LED lamp socket, heat pipe, radiating component, one end of its light fitting main casing is provided with the heat pipe connector, one end of heat pipe connector is provided with and is no less than one or one group of heat pipe and is connected in the LED lamp socket, the other end of heat pipe connector is provided with and is no less than that one or one group of heat pipe are connected in external radiator combination and the cooling system that constitutes is characterized in that: the radiating element of its LED supply unit is provided with and is no less than one or one group of heat pipe and is connected with cooling system.The radiating element of its LED supply unit can be connected to any one or a plurality of heat pipe interface in the cooling system with heat pipe.Its LED supply unit is connected with cooling system, is preferably the heat pipe position that is connected to the LED lamp socket, that is: the radiating element of its LED supply unit is connected in heat pipe or the heat pipe interface that is located at the LED lamp socket.The distance of the two can reach the shortest like this, and it is minimum to consume heat resistant material, helps reducing cost.LED supply unit of the present invention, the available different types of prior art or the LED supply unit of model of comprising.For the LED supply unit.As everyone knows, generally speaking, in its basic circuit system, silicon-controlled rectifying switch diode (or claiming switching tube or rectifying tube) is arranged all; This device can generate heat at work, maintains the low value scope of a regulation in order to protect its operating temperature just, generally all is this device to be installed be connected on the radiator; Its radiator reaches radiating effect with thermal-radiating radiating mode.In other words, by the air natural heat dissipation.Because the cavity temperature of LED road lamp is higher, be placed in the LED supply unit in the LED road lamp, its radiator and the temperature difference on every side are very little or do not had the temperature difference, and its radiator plays the thermal-arrest effect at this, does not have thermolysis; The present invention adopts the heat pipe for thermal conductivity method, and its heat is shifted out, and has solved LED supply unit heat dissipation problem effectively.
The invention has the beneficial effects as follows:
Large power solid-state illumination street light fitting of the present invention, designed by hot pipe network and connect mode and the outer cooling system scheme that constitutes, when migrating out the heat that super-high-power LED work sends rapidly, the heat of supply unit is forced to take out of together by Heat Pipes, the LED that makes ultra-high power LED street lamp and the supply unit working temperature that make are lower, thereby the whole working temperature of ultra-high power LED street lamp significantly reduces, reach and realize that the LED lamp increases purpose service life, solved the heat dissipation technology difficult problem of high-power LED lamp effectively, made ultra-high power LED street lamp realize large-scale industrialization production and use.
