Description

A kind of high-powered LED lamp

Technical field

The present invention relates to a kind of illuminating lamp, especially a kind of LED lamp.

Background technology

At present, the bulb of most lamps still adopts the luminous principle of filament heating to make on market, and its power supply conversion efficiency is low, and the energy major part loses with the form of heat, and service life is short, troublesome maintenance.

Because the appearance of LED (light emitting diode), therefore advantages such as it has energy-saving and environmental protection, the life-span is long, driving voltage is low, light efficiency is high, radiationless, shock resistance hold out broad prospects on the bulb lamp applications.Though also occurred the bulb of few a part of LED in the market, especially with the decorating lamp bulb of low-power LED making, quality is uneven, and major part exists problems such as brightness is not enough, power is limited, radiating effect is poor, optical attenuation is fast, cost height.The illuminating lamp of great power LED does not solve heat dissipation problem mainly due to also good, and can not get large-area promotion and application.

Summary of the invention

Shortcoming at existing LED lamp the invention provides a kind of high-powered LED lamp.

In order to realize above-mentioned purpose, the scheme that the present invention taked is: the structure of this high-powered LED lamp is, two contact pins that connect two electrodes are packed in the insulating part, the insulating part close-fitting is installed in the interior cavity of pedestal, the plastic cement external member is fixedly mounted on an end of pedestal, is separately installed with the lens of LED and dome-type on the pedestal.Wherein said chip is a high-power LED chip, also can be the packaged LED of band heat-radiating substrate.Pedestal is an all-in-one-piece cylindrical-shaped structure.Base-plates surface is distributed with fin, can horizontal, vertical or irregular distribution, can be good at the heat that LED produces is exhaled; Pedestal one end is formed by stacking by the diminishing cylinder of several diameters, and the cylinder size of stack is corresponding with groove with the through hole of plastic cement external member respectively.Wherein LED just is installed on topmost the cylindrical protrusion, and is provided with two little flutings in its both sides, is provided with two through holes in the inside of fluting accordingly, directly and the oval hole slot of the other end of pedestal link to each other, as the passage of lead connection; The other end at pedestal is provided with oval hole slot, is used for fixing insulating part.By two metal pins in the plastic cement external member two electrodes on the LED are drawn, link to each other with contact pin by the through hole in the fluting with lead, wherein contact pin directly is fixed in the insulating part when making.Lens are fixed on the pedestal at last, can adopt different lens to regulate its lighting angle as required.

Described LED is a high-power LED chip, also can be the packaged LED of band heat-radiating substrate.

Described pedestal is a monolithic construction.

Described pedestal one end is formed by stacking by the diminishing cylinder of several diameters.

Described base-plates surface is manufactured with fin.

Described fin can be horizontal, vertical or random distribution.

Described fin quantity can increase or reduce.

Described insulating part can adopt heat proof materials such as ABS, pottery.

The present invention can improve the radiating efficiency of LED, especially by the fin of all-in-one-piece base-plates surface, effectively raises heat conduction and radiating effect, and the LED light decay is slowed down, and has improved its service life.

The specific embodiment

See also Fig. 1,2,3 as can be known, the present invention is made up oflens 1, plastic cementexternal member 2, LED (light emitting diode) 3,pedestal 4, insulatingpart 5, contact pin 6.Twocontact pins 6 that connect two electrodes are packed in 5 li of insulating parts, 6 fixing and insulating effects of 5 pairs two contact pins of insulatingpart.Insulating part 5 close-fittings are installed in the cavity in thepedestal 4, and pedestal has a cavity for 4 li.Plastic cementexternal member 2 is fixedly mounted on an end ofpedestal 4, is separately installed with thelens 1 of LED3 and dome-type on the pedestal.Two leads, one end connects twocontact pins 6 respectively, and alongpedestal 4 internal cavities (promptly slotting 45, through hole 47) cabling, the other end links to each other with twometal pins 21 respectively then again.The other end of twometal pins 21 links to each other with two electrodes of LED by lead respectively.Connect power supply like this, just can carry out power supply LED.

Shown in Fig. 3,4,5,pedestal 4 is a mounting platform of whole bulb, and it is an all-in-one-piece cylindrical-shaped structure.Surface distributed hasfin 41, can horizontal, vertical or irregular distribution, be provided with two throughholes 47 in the inside of fluting 45 accordingly.The other end atpedestal 4 is provided withoval hole slot 46, and insulatingpart 5 close-fittings are installed in 46 li of circular hole slots in the pedestal 4.LED3 is welded in thegroove 24, and has twometal pins 21 that two electrodes on the LED3 are drawn, and links to each other withcontact pin 6 by the throughhole 47 in the fluting with lead, and whereincontact pin 6 directly is fixed in theinsulating part 5 when making.The edge oflens 1 is manufactured with fourpins 11, and itsjack 47 with pedestal one end is corresponding, and both are fixed onlens 1 on the pedestal, when adjusting lighting angle, also can effectively protect LED3.

LED3 is a high-power LED chip, also can be the packaged LED of band heat-radiating substrate.

Pedestal 4 is a monolithic construction, andpedestal 4 one ends are formed by stacking by the diminishing cylinder of several diameters (42,43,44).This cylinder can be class cylinder or round platform.Pedestal 4 surfaces are manufactured withfin 41, andfin 41 can be horizontal, vertical or random distribution, andpedestal 4 is cylindric or prism-shaped.The material ofpedestal 4 is at least a in aluminium, zinc, copper, pottery, the aluminium alloy.

Fin 41 quantity can increase or reduce.

Insulating part (plug-in unit of PIN seat) 5 can adopt heat proof materials such as ABS, pottery, and twocontact pins 6 are arranged on the insulating part.Only twocontact pins 6 need be inserted in the power supply during use, just can realize LED is powered.
