Abstract

An LED lamp inner lobe aluminum pipe fan airflow radiating device pertains to a radiating device. LEDs and ballasts (4) are all arranged in 2 to 30 lines on the surface of an inner lobe aluminum pipe (12) in parallel connection; 3 to 320 in each line are arranged on a mounting circuit board (6) to form a module; an LED power bus (2) is led out to cover the module on the external surface of the inner lobe aluminum pipe (12) with an insulating plate (8) and in a light permeable shell (5); an insulating thermal conductive grease (7) is filled between the mounting circuit board (6) and the insulating plate (8) and then an inner lower cover (10) is added; then an inner upper cover (1) is arranged in an upper cover (3) so as to be used as an upper cover module for sealing the light permeable shell (5). In addition, one end of the inner lobe aluminum pipe (12) is provided with an axial flow fan (14) which can effectively emit the heat produced in the operation of LED through an airflow channel which is composed of an aluminum pipe and the inner lobe of the aluminum pipe. Therefore, the LED can work in the normal temperature and moisture range and effectively utilize the effective service life of LED. The utility model is suitable for LED lighting fixture.

Description

LED lamp internal lobe aluminum pipe fan airstream heat abstractor

Technical field:

The utility model relates to the LED lighting, particularly a kind of LED lamp internal lobe aluminum pipe fan airstream heat abstractor.

Background technology:

The single lamp of existing illumination roughly is a three major types, and the incandescent lamp bulb of the red-hot formula glass shell of first kind high energy consumption is characterized in that electro-optical efficiency is low, filament temperature is up to more than 3000 ℃, life-span is short, and not substantive breakthroughs as yet so far are again because its shell generally is that easily fragmentation is dangerous for glass material; Second class is an electronic circuit integrated energy-saving fluorescent lamp, and its electro-optical efficiency height can reach the several times of incandescent lamp usually, and the life-span also improves a lot, but its illuminator shell is still glass material, and same frangible dangerous, its life-span also is several thousand hours; The 3rd class is product---the LED energy-saving lighting lamp of third generation illumination revolution, its electro-optical efficiency height, life-span reaches tens thousand of hours, but the overwhelming majority is that LED is assemblied on the common line plate of common paper substrate or glass fabricbase at present, use plastic casing, even surrounding air better also is difficult to resolve certainly LED lamp body heat dissipation problem, causes LED to distribute with moisture problems and be difficult to fully increase the service life because of heat collection difficulty.

Summary of the invention:

The purpose of this utility model is to provide a kind of LED lamp internal lobe aluminum pipe fan airstream heat abstractor, and the heat that produces when it can be worked LED is successfully distributed in the lamp external space by the gas channel of the intra vane formation of aluminum pipe and aluminum pipe, reaches the purpose of heat radiation.

Formation of the present utility model: by the aluminum pipe that carries intra vane, LED and ballast spare thereof, the LED power bus, thermal grease conduction, mounting circuit boards, insulating trip, light transmitting shell, interior loam cake, loam cake, interior lower cover, loam cake turnover transom window, gas channel and axial flow blower constitute, with LED and ballast spare 4 thereof all in parallel, with straight line, curve or helix are arranged as row, it is capable to arrange 2-30 at intra vane aluminum pipe 12 side faces, every capable 2-320 arrangement states only is installed on mounting circuit boards 6 and arranges or roll up is tubular constituent components, draw the LED power bus 2 that is connected with power supply source simultaneously, the outer surface that this assembly is placed in the intra vane aluminum pipe 12 that aluminum pipe intra vane 13 is arranged that posts insulating trip 8 becomes integration component and is set in the light transmitting shell 5, and lower cover 10 sealings are firm in adding a cover behind the filling insulating heat-conductive fat 7 between mounting circuit boards 6 and insulating trip 8, again interior loam cake 1 being packed into becomes the cover assembly bonnet in the loam cake 3 and is encapsulated on the light transmitting shell 5, again in an end installation shaft flow fan 14 of intra vane aluminum pipe 12;

The cast cross section that carries the aluminum pipe of intra vane can be circular, square, rectangle, semicircle, ellipse, polygon or other special-shaped tubular structures respectively.

Compared with the prior art, the heat that produces when the utility model can be worked LED is effectively successfully distributed in the lamp external space by the gas channel of the intra vane formation of aluminum pipe and aluminum pipe, and can seal to a certain extent, prevent that dust and aqueous vapor from entering in the LED lamp housing, make LED work in the scope of normal temperature and humidity and bring into play the useful life of LED effectively.
