Description

LED lamp crown cap heat abstractor

Technical field:

The utility model relates to the LED lighting, particularly a kind of LED lamp crown cap 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 electric light changes the efficient 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 crown cap heat abstractor, it is a kind ofly to be transmitted to the heat abstractor that shell is dispersed into the lamp external space again with the heat that produces when the excessive aluminium box of heat conduction is worked LED is set in the LED lamp, guarantees that effectively LED works in normal temperature, humidity range.

Formation of the present utility model: by air chamber, the excessive aluminium basin of heat conduction, sealing ring, euphotic cover, crown cap, thermal grease conduction, LED ballast spare, LED, insulating trip, LED power bus and mounting circuit boards constitute, 1～800 LED8 and LED ballast spare 7 thereof installed with parallel way be welded on the mounting circuit boards 11 and draw LED power bus 10, again this assembly is packed in the euphotic cover 4, thermal grease conduction 6 is arranged on mounting circuit boards 11, insulating trip 9, heat being conducted excessive aluminium basin 2 is fitted in the euphotic cover 4 again, it is contacted with insulating trip 9 tight faces, conduct the periphery of excessive aluminium basin 2 and the mouth placement sealing ring 3 of euphotic cover 4 in heat, afterwards crown cap 5 tightly is stuck in the outer rim of euphotic cover 4, makes euphotic cover 4, crown cap 5, the bonding crack of the excessive aluminium basin 2 of heat conduction is by sealing ring 3 sealings.

Compared with the prior art, the heat that produces when the utility model can be worked LED effectively excessively is transmitted to crown cap 5 by the aluminium basin and successfully distributes in space outerpace, and prevent that steam from entering in the lamp, guarantee effectively that LED works in normal temperature, humidity range and service life of giving full play to LED.

Description of drawings:

Fig. 1 is that mounting circuit boards is the construction for heat radiating device schematic diagram of aluminium base; Fig. 2 is that mounting circuit boards is the construction for heat radiating device schematic diagram of common fire-retardant circuit substrate.

1. air chambers among the figure, the 2. excessive aluminium basin of heat conduction, 3. sealing ring, 4. euphotic cover, 5. crown cap, 6. thermal grease conduction, 7.LED ballast spare, 8.LED, 9. insulating trip, 10.LED power bus, 11. mounting circuit boards.

The specific embodiment:

With 1～800 LED8 and LED ballast spare 7 install be welded on the mounting circuit boards 11 and draw LED power bus 10 after this assembly is packed in the euphotic cover 4, on mounting circuit boards 11, fill out thermal grease conduction 6, on the pad behind the insulating trip 9, again heat is conducted excessive aluminium basin 2 covers be placed on euphotic cover 4 outer rim and with insulating trip 9 closely face contact, again after heat is conducted the mouth of excessive aluminium basin 2 outer race and euphotic cover 4 limit is put sealing ring 3, crown cap 5 is stuck in euphotic cover 4 outer rims and keeps simultaneously contact, pass through thermal grease conduction 6 with the heat that guarantees LED8 work generation with the good face of the excessive aluminium basin 2 of heat conduction, heat excessive aluminium basin 2 of conduction and crown cap 5 distribute in the external space and prevent that steam from entering in the lamp.Air in the air chamber 1 is that nature stops thing.
