The heat dissipation structure of light-emitting diode lamps mainly comprises a light-emitting diode (1), a metal welding board (2), a heat dissipation metal seat (3), a heat-conducting insulating layer (4), and an insulating batten (6). The heat dissipation structure of light-emitting diode lamps can be widely used in lamps using light-emitting diodes as light sources.
Description
Technical field
The utility model relates to a kind of radiator structure of LED lamp, relates in particular to the radiator structure of a kind of integrated use LED as lighting source.
Background technology
LED has long characteristics of the high and low heating of luminous efficiency, power saving and life-span, therefore uses more and more widely.Single led luminous quantity is limited, if will be used for normal lighting, then will especially for the higher light fixtures such as shot-light of brightness requirement, require integrated LED more the densely arranged integrated together use of a plurality of LED, and promptly closeness is higher.But, LED is very high to the temperature requirement of environment, the LED lantern festival that high integration is used causes heat to accumulate in a large number in the less space and can not distribute rapidly, when LED and environment temperature reach balance, the temperature of LED is very high, thereby cause the decay of LED illumination and aging rapidly, shorten service life greatly.Present LED light fixture generally is that LED is integrated on traditional single face wiring board, because traditional wiring board thermal resistance is big, and heat transfer, area of dissipation are little, can only lean on the heat radiation of LED pin, therefore its radiating efficiency is very low, thereby has limited the scope of application of high illuminance LED lamp.
So existing technology has the following disadvantages: radiating effect is poor, influence life-span and the integrated level of LED, simple in structure, cost is low.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of good heat dissipation effect is provided, improves LED life-span and integrated level, the radiator structure of simple in structure, LED lamp that cost is low.
The technical scheme that the utility model adopted is: the utility model comprises several LED, the radiator structure of described LED lamp also comprises several metal welding plates, heat radiating metal seat, heat conductive insulating layer, the two poles of the earth of described LED are connected on two described metal welding plates by pin respectively, several described metal welding plates by described heat conductive insulating interlayer every being arranged on described heat radiating metal seat upper surface.
Described metal welding plate is vertical bar shaped or concentric ring bar shaped.
The lower surface of described heat radiating metal seat is provided with the radiating fin of some projectioies.
The radiator structure of described LED lamp also comprises one or more than one insulation press strips, and described insulation press strip is arranged on the described metal welding plate and by screw and is connected with described heat radiating metal seat.
The beneficial effects of the utility model are: because the utility model is provided with metal welding plate, heat radiating metal seat, heat conductive insulating layer, the heat that LED produces passes to described metal welding plate by pin, finally pass on the heat radiating metal seat by metal welding plate, heat conductive insulating layer again, the heat radiating metal seat can distribute heat fast, keep lower temperature around making LED, so thereby good heat dissipation effect can improve LED life-span and integrated level; Because the two poles of the earth of described LED are connected on two described metal welding plates by pin respectively, the metal welding plate just by described heat conductive insulating interlayer every being arranged on described heat radiating metal seat upper surface, saved the expense of wiring board, so simple in structure, cost is low; Owing to be provided with the insulation press strip, the insulation press strip can be fixed on the metal welding plate on the heat radiating metal seat well simply, and is so firmly, simple in structure, cost is low.
