Semiconductor LED is just energy-conservation with it in recent years, high brightness, advantages such as environmental protection have become main trend in the development of light fixture industry, but because the requirement of led light source self-radiating, the light fixture outward appearance often do more complicated, the loaded down with trivial details fin form of many employings, weight is substantially all more than 15 kilograms, even and can not reach the requirement of led light source heat radiation like this, so directly influenced the whole light decay of LED light fixture, and then cause that electrical quantity changes, make light source and power supply whole system unstability occur, so the LED street lamp life-span is no more than a year and a half at most now, this radiating mode is through facts have proved, be not suitable for led light source heat radiation standard, heat dissipation problem has become the main difficult problem of puzzlement LED light fixture development.
Summary of the invention
Task of the present invention provide a kind of simple in structure, volume is little, the LED lighting of rapid heat dissipation.
Technical scheme of the present invention is as follows:
A kind of LED light fixture, comprise lamp outer casing, heat abstractor and led light source part, led light source partly comprises metal pcb board and the LED that is welded on the metal pcb board, it is characterized in that: described heat abstractor comprises copper coin and super heat-conductive pipe, copper coin is installed in the back side of metal pcb board and is connected with the metal pcb board, the part of super heat-conductive pipe is fixed in the copper coin, and fin is installed on super heat-conductive pipe.The metal pcb board is except that the effect with fixed L ED but also be the first road heat transfer medium of LED, so the heat conductivility of metal pcb board is related to the quality of LED light fixture integral heat sink.The heat of LED is delivered to copper coin by the metal pcb board, rapidly heat is dissipated by super heat-conductive pipe and fin by copper coin, makes the LED fast cooling.
The part of described super heat-conductive pipe is embedded in the copper coin, and fin is laminated structure and is nested on the super heat-conductive pipe at intervals.This structure has fully increased the contact area of fin and air, and helps the mobile of air and help allowing air take away the heat of fin fast.
The part of described super heat-conductive pipe is embedded in the copper coin and an end stretches out copper coin, and the other end of super heat-conductive pipe is arranged on the wherein side of copper coin by the dogleg section in the middle of the super heat-conductive pipe, and described fin is arranged on the super heat-conductive pipe of copper coin side.
The center line of the described super heat-conductive pipe that is arranged on the copper coin both sides about about copper coin is symmetrical arranged.
On the described copper coin fan is installed, replaces natural heat dissipation, accelerated flowing of air, make air take away heat fast, accelerated radiating rate greatly with the air-cooled mode of active.
Also be provided with fin on described copper coin, fin is installed between copper coin and the fan, and each the piece fin on the copper coin is made of one piece with the corresponding fin on the relevant position that is arranged on the copper coin both sides.
The described top plan that is arranged on the fin on the copper coin is lower than the top plan of the fin that is arranged on the copper coin both sides, the fin of fin on being arranged on copper coin that is arranged on the copper coin both sides constitutes the low structure in height middle part, both sides, and described fan places the central authorities of central region.This structure all plays a role fan simultaneously in vertical and horizontal direction, made full use of fan air-out characteristics, has given play to maximum effectiveness.
Described fin is copper sheet or aluminium flake.
Described metal pcb board is the copper-clad plate of copper base.The metal pcb board is the first road heat transfer medium of LED, heat radiation to LED has crucial effects, and the copper-clad plate of copper base has good heat transfer property, the copper base copper-clad plate has better heat dispersion than the basic copper-clad plate of other metal, copper is as the heat conduction high-end product, simultaneously also there is the plate face smooth, the intensity height, dimensional stability is good, characteristics such as easy processing, especially its thermal resistance is little, and heat-transfer rate is fast, and thermal capacity is big, especially be fit to do the heat radiation heat transfer carrier that this heat of led light source is concentrated, led light source stability can greatly be provided, prolong the led light source life-span, guarantee the light fixture total quality.
The described LED that is welded on the metal pcb board is patch-type LED, and becomes matrix form to arrange.
Advantage of the present invention be simple in structure, volume is little, in light weight, avoided the shortcoming of the big weight of traditional high-power LED lamp, large volume and radiator structure complexity, moreover, the present invention has also improved the radiating rate of high-power LED lamp.
