Description

Aluminum pipe air-flow speed-raising heat abstractor in the LED lamp

Technical field:

The utility model relates to the LED lighting, aluminum pipe air-flow speed-raising heat abstractor in particularly a kind of LED lamp.

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 aluminum pipe air-flow speed-raising heat abstractor in a kind of LED lamp, it be in a kind of LED lamp vaned aluminum pipe with the air-flow heat abstractor that raises speed, the heat that produces when it 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, reaches the purpose of heat radiation.

Formation of the present utility model: by carrying the intra vane aluminum pipe, 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 constitutes, with LED and ballast spare 4 thereof all with parallel way, with straight line, curve or helix are arranged as row, face arrangement 2-30 is capable around intra vane aluminum pipe 12 is arranged, every capable 2-320 arrangement states only is installed on mounting circuit boards 6 and arranges or roll up is tubular constituent components, draw LED power bus 2 simultaneously, the outer surface that again this assembly is placed in the intra vane aluminum pipe 12 that intra vane 13 is arranged that posts insulating trip 8 becomes integration component and is set in the light transmitting shell 5, and between mounting circuit boards 6 and insulating trip 8, fill thermal grease conduction 7, add a cover interior lower cover 10 sealings of lamp firmly, become the assembly bonnet in the loam cake 3 of again interior loam cake 1 being packed into and be encapsulated on the light transmitting shell 5;

The cast cross section that carries the aluminum pipe of intra vane respectively can be round, square, square type, semi-circular, ellipse, polygonal or other special-shaped tubular structures.

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 and 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.

Description of drawings:
