Abstract

A heat radiation device for an energy-saving LED lamp belongs to a lighting lamp. LED and corresponding elements (4) of LED are arranged on a copper foil circuit (7) on an insulated and insolated layer (3) at one side of an aluminum substrate (2) of an aluminum composite circuit board, and lead out a connecting wire of a LED working power. Then an aluminum plate (2) at the other side of the insulated and isolated layer (3) is closely combined with an upper metal cover (1) on a large contact surface. The transparent, dustproof and moistureproof cover (5) covers one side, which is equipped with LED and corresponding elements (4) of LED. LED and corresponding elements (4) of LED together with a paraboloid become a basic electro-optical unit. Two or a plurality of basic electro-optical units forms a matrix. The invention can effectively radiate the heat produced by LED at work to the surrounding space of the lamp via the aluminum substrate and the upper metal cover, and effectively guarantee that LED works within the allowed normal working temperature scope. Moreover, the invention can prevent moisture or dust into the lamp to effectively guarantee the usable life of LED, and is suitable for lighting lamps.

Description

The heat abstractor of LED electricity-saving lamp

Technical field: the present invention relates to lighting, particularly a kind of heat abstractor of LED electricity-saving lamp.

Background technology: the single lamp of existing illumination roughly is a three major types; The incandescent lamp bulb of the red-hot formula glass shell of first kind high energy consumption; Be characterized in that electro-optical efficiency is low, filament temperature is up to more than 3000 ℃, and the life-span is short; So far not substantive breakthroughs as yet, easy fragmentation is dangerous because its shell generally is a glass material again; Second type is electronic circuit integrated energy-saving fluorescent lamp, and its electro-optical efficiency is high, can reach the several times of incandescent lamp usually; Life-span also improves a lot; But its illuminator shell is still glass material, exists frangible dangerously equally, and its life-span also is several thousand hours; The 3rd type is the product-LED energy-saving lighting lamp of third generation illumination revolution; Its electro-optical efficiency is high, and the 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; Promptly ventilate and also be difficult to resolve certainly heat dissipation problem, also exist simultaneously to be difficult to moistureproof dustproof problem, high and moisture problems is difficult to fully increase the service life because of heat to cause LED.

Summary of the invention: the heat abstractor that the object of the present invention is to provide a kind of LED electricity-saving lamp; It is a kind ofly to have the attaching on the copper foil circuit of intermediate insulation separation layer with what LED and kit thereof were installed on aluminium base compound circuit plate; The another side of intermediate insulation separation layer is the good aluminium base of heat radiation; Again the upper metal shell of this aluminium base and LED lamp is combined closely; Make heat that LED work produces by aluminium base with metal shell conduction distribute in space outerpace, guarantee that effectively the LED lamp is operated in normal temperature range, it is interior and reach the purpose that increases the service life to prevent that moisture from getting into lamp in a large number simultaneously again.

Formation of the present invention; Constitute by upper metal cap, aluminium base compound circuit plate, LED and kit thereof, LED working power tie-in line, printing opacity dust and moisture lid; LED andkit 4 thereof are installed on attaching on thecopper foil circuit 7 on 3 of the dielectric isolation layers ofaluminium base 2 one side of aluminium base compound circuit plate; And draw LED working power tie-inline 6; Again with thealuminium base 2 of the aluminium base compound circuit plate ofdielectric isolation layer 3 another sides combining closely than large contact surface and upper metal cap 1, and printing opacity dust andmoisture lid 5 is placed on the one side that LED andkit 4 thereof are installed.

LED andkit 4 thereof are equipped with parabolic 8 becomes basic electrooptics unit, two constitutes matrixes to some cover electrooptics elementary cells thus again.

Compare with prior art; The heat that the present invention distributes in the time of effectively LED being worked is through aluminium base and upper metal cap; Distribute surrounding space effectively in lamp; And guarantee that effectively LED works in the normal permission operating temperature range, can prevent that again the moisture dust from getting in the lamp, guarantees the service life of LED effectively.

1. upper metal caps among the figure, the aluminium base of 2. aluminium base compound circuit plate, 3. dielectric isolation layer, 4.LED and kit thereof, 5. printing opacity dust and moisture lid, 6.LED working power tie-inline 7. attaches copper foil circuit, 8. parabola.

The specific embodiment: byaluminium base 2, thedielectric isolation layer 3 of aluminium base compound circuit plate with attachcopper foil circuit 7 and constitute; To attach Copper Foil earlier and process the requiredcopper foil circuit 7 that attaches; Attaching installation LED andkit 4 thereof on thecopper foil circuit 7; And draw LED working power tie-inline 6; Again with installations of combining closely of upper metal cap 1 andaluminium base 2, printing opacity dust andmoisture lid 5 is installed inaluminium base 2 LED and the one side ofkit 4 thereof behind, and available upper shield or overlap card or screw or bound edge and fixed by upper metal cap 1 Ka Gai or extended surface limit mode; What need directed light harvesting then gives LED4 with addition of parabolic 8 becoming basic electrooptics unit, two constituting matrixes to some cover electrooptics elementary cells thus more again, places between LED andkit 4 thereof and the printing opacity dust andmoisture lid 5.
