Abstract

An LED lamp stovepipe-type airflow supply/suction heat sink belongs to an LED illuminating lamp. LED (4) are connected in parallel and are arranged on the periphery of an intra vane aluminum pipe (12) in the manner of 3-320 units in each of 1-30 rows; an LED power bus (3) is leaded out on a mounting circuit board (6) and are installed in a transparent outer cover (5); heat conduction grease (7) is filled between the mounting circuit board (6) and an insulating piece (8), and is equipped with a lamp inner cover (10); an upper cover (2) equipped with a stovepipe-type air-suction pipe (9) is installed at the upper part of the transparent outer cover (5), a top cover (1) is installed at the top part of stovepipe-type air-suction pipe (9), and then the assembly is installed at the upper part of a stovepipe-type air-supply pipe (15). The LED lamp stovepipe-type airflow supply/suction heat sink can efficiently and smoothly radiate the heated generated by LED working out of the lamp via an airflow rapid passage which is formed by the aluminum pipe and the intra vane as well as a stovepipe-type up/down airflow accelerative pipe, so that the LED work in the normal temperature and the humidity ranges, the efficient service life of LED can be efficiently exerted, and the LED lamp stovepipe-type airflow supply/suction heat sink is applicable to the LED illuminating lamp.

Description

LED lamp black chimney tubular type is sent the wandering thermic devices of bleeding

Technical field:

The utility model relates to the LED lighting, and particularly a kind of LED lamp black chimney tubular type is sent the wandering thermic devices of bleeding.

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 black chimney tubular type to send the wandering thermic devices of bleeding, aluminum pipe and aluminum pipe upper and lower side are installed the chimney tubular type and are sent the wandering thermic devices of bleeding in the LED lamp, the heat that produces when it can be worked LED is effectively successfully distributed in the lamp external space by the intra vane of aluminum pipe and aluminum pipe and the quick gas channel of chimney current accelerating tube formation, reaches the purpose of heat radiation.

Formation of the present utility model: by the intra vane aluminum pipe, LED, the LED power bus, thermal grease conduction, mounting circuit boards, insulating trip, the printing opacity enclosing cover, top cover, funnel-shaped exhaust tube, funnel-shaped snorkel, gas channel constitutes, with LED 4 all in parallel, with straight line, curve or helix are arranged as row, face arrangement installation 1-30 is capable around face around the intra vane aluminum pipe 12 or part, every capable 3-320 intensive or interval arrangement states only is installed on the mounting circuit boards 6, and arrange or volume is the plane cast for tubular or group row, sphere cast or other differential mode cast constituent components, draw LED power bus 3 simultaneously, the surface that this assembly is installed on the intra vane aluminum pipe 12 of the aluminum pipe intra vane 13 that posts insulating trip 8 becomes integration component and is installed in the printing opacity enclosing cover 5, full-filling thermal grease conduction 7 between mounting circuit boards 6 and insulating trip 8, it is firm to add a cover 10 sealing-ins of lamp inner cap, the loam cake 2 that funnel-shaped exhaust tube 9 is housed is installed in printing opacity enclosing cover 5 tops to be become behind the assembly simultaneously the top at funnel-shaped exhaust tube 9 top cover 1 is installed, and then this grip assembly is installed on the top of funnel-shaped snorkel 15, and offer funnel-shaped snorkel 15 airflow inlets 14 at the lower port or the downside of snorkel 15.

The cast cross section that carries the intra vane aluminum pipe can be circular, square, rectangle, semicircle, ellipse or other special-shaped tubular structures respectively; The LED cohort can also be arranged in pipe arbitrary part of face on every side.

It can be respectively horizontal type, vertical, tilting that the LED lamp is settled state, and stovepipe arrangement state is necessary for tilting or vertical type.

Compared with the prior art, the air-flow express passway that intra vane and the funnel-shaped upper and lower air-flow accelerating tube of the heat that produces when the utility model can be worked LED effectively by aluminum pipe and aluminum pipe constitutes is successfully distributed in the lamp external space, makes LED work in the scope of normal temperature and humidity and brings into play the useful life of LED effectively.
