Description

LED lamp water cooling heat abstractor

Technical field:

The utility model relates to the LED lighting, particularly a kind of LED lamp water cooling 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 has only 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 water cooling heat abstractor, the heat that produces when this device can be worked LED is effectively successfully distributed in the lamp space by the water stream channel of the intra vane formation of aluminum pipe and aluminum pipe, makes LED work in the scope of normal temperature and humidity.

Formation of the present utility model: level and smooth or carry the aluminum pipe of intra vane by inwall, LED and ballast spare thereof, the LED power bus, thermal grease conduction, mounting circuit boards, insulating trip, light transmitting shell, the loam cake edge, loam cake, the sump cavity, sump sealing loam cake, sump sealing lower cover, the turnover water valve constitutes, the aluminum pipe 13 that will have intra vane 14 or smooth internal walls is loaded onto sump sealing loam cake 10 and sump sealing lower cover 15, refill enterprising outlet valve 1,16 become sump cavity assembly, again with luminous angle greater than 50 ° LED3 and LED ballast spare 12 thereof all in the mode of parallel operation, with straight line, curve or helix are arranged as keeps straight on or bent row, it is capable to arrange 2-30 at sump assembly aluminum pipe 13 outer peripheral faces, every capable 2-320 arrangement states welded and installed only constituent components and draw LED power bus 11 on mounting circuit boards 5 is again with this assembly with common LED 3 and common mounting circuit boards 5 welded and installed, arrangement or volume are filled thermal grease conduction 6 for the outer surface that tubular casing is loaded on the sump cavity assembly aluminum pipe 13 that posts insulating trip 7 between mounting circuit boards 5 and insulating trip 7; Arrange or volume is that the outer surface that tubular casing is loaded on the aluminum pipe reason 13 of posting insulating trip 7 is filled thermal grease conduction 6 between circuit board 5 and insulating trip 7 with this assembly that mounts LED3 and aluminium base mounting circuit boards 5; Then this is contained sump cavity assembly in pack into light transmitting shell 4 and install loam cake 9 sealing additional firmly of interior integration component;

Aluminum pipe can be with blade and not be with blade, and the cast cross section 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 water stream 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.

Description of drawings:
