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.
Summary of the invention
The objective of the invention is a heat radiation difficult problem, design a kind of external radiator high-power LED street lamp fixture of being with at the above ultra-high power LED street lamp of great power LED cooling technical barrier, particularly 25W more than the present 5W.
Of the present inventionly be with external radiator high-power LED street lamp fixture, comprise light fitting main casing, lampshade, the LED lamp, external radiator, the power circuit system critical piece constitutes, it is characterized in that: comprise housing (1) on its light fitting main casing, heat pipe connector (2), LED lamp socket (3), heat pipe (8), radiating component (6) constitutes, one end of its light fitting main casing is provided with heat pipe connector (2), one end of heat pipe connector (2) is provided with and is no less than one or one group of heat pipe and is connected in LED lamp socket (3), and the other end of heat pipe connector (2) is provided with and is no less than one or one group of heat pipe and is connected in external radiator.Its external radiator constitutes by being no less than the combination of two unit member couplings.Heat pipe (8) outer edge (27) on the LED lamp socket (3), the size (C1) that is cut in the plane (25) of lamp socket (3) or exceeds plane (25) is for being not less than 0.2mm.Make heat pipe can be directly with the substrate of LED lamp or tight base is close combines, play the effect that the heat that makes LED is removed fast.The foundry goods that the housing that comprises on the described light fitting main casing (1), heat pipe connector (2), LED lamp socket (3), radiating component (6) are formed in one or constitute in the parts mode respectively.For reaching the purpose that improves heat-conducting effect, the housing that its light fitting main casing comprises (1), heat pipe connector (2), LED lamp socket (3), radiating component (6) are good with integrated formed structure, with integrated metal casting structure, can obtain better optimum efficiency.Heat pipe connector (2) cooperates with external radiator, can adopt the existing interconnection technique of separate type to finish, and connects for good to adopt concavo-convex coupling, and it can make more firm, the reliable while of connection, also can play the effect of auxiliary transmission heat radiation.Radiator can constitute by pin is fixing by being no less than two unit member (or claiming the unit parts) coupling combination, and radiator (9) is provided with fin (10), heat pipe interface (11).It can be designed to two combinations of radiator, four products such as combination, is combined as best design with four unit member couplings.It can adopt the art methods manufacturing to finish.For easy for installation, on LED lamp socket (3), be provided with screw (20b), be provided with in the housing that lamp stand fixedly fastens screw (22) so that install.Also can be equipped with fixedly snap ring (21), but also can be unworthy of, can adopt art methods to finish as the case may be flexiblely.Its power circuit system and installation, connection etc. all can be adopted art methods.The LED lamp is more convenient in the installation of lamp socket (3), the fixing general screw bolt method of using, and also can adopt art methods to finish.
The invention has the beneficial effects as follows:
Of the present inventionly be with external radiator high-power LED street lamp fixture, be provided with external radiator in the design, the heat that sends in the time of can migrating out super-high-power LED work rapidly, not only can satisfy the needs of high-power LED lamp heat radiation effectively, the working temperature that makes ultra-high power LED street lamp that can make is lower, increased the service life of ultra-high power LED street lamp, solved the great power LED cooling technical barrier effectively, make ultra-high power LED street lamp realize large-scale industrialization production and use.
