Abstract
The utility model discloses an aluminum base with high efficient heat dissipation performance. The aluminum base comprises an aluminum plate (1), an insulating heat-conduction layer (2), a copper foil layer (3), electrodes (4) and a pedestal hole (5). In the aluminum base with high efficient heat dissipation performance, interlaced lines are carved on the bottom surface of the aluminum plate (1), and the low-thermal resistance insulating heat-conduction layer (2) is arranged on the upper surface of the aluminum plate (1); the copper foil layer (3) is located at the upper part of the insulating heat-conduction layer (2), the pedestal hole (5) is arranged in the copper foil layer (3), and two ends of the pedestal hole (5) are provided with two matched electrodes (4), so the problems of single production material for the insulating heat-conduction layer and influence on system heat-dissipation process caused by high thermal resistance of the insulating heat-conduction material are solved. In comparison with the conventional aluminum base, the aluminum base of the utility model is featured by simple structure, excellent heat-dissipation performance and the like, and can improve the service life and the stability of light emitting diodes.
Description
Technical field
The utility model relates to a kind of high-efficiency heat-radiating aluminum plate.
Background technology
Aluminium base in the market is divided into 3 layers mostly: one deck is a copper foil layer; Two layers is the insulating heat-conductive layer; Three layers is aluminium sheet, and copper foil layer plays a part bearer circuit, is generally used for conduction; The insulating heat-conductive layer plays the heat that produces LED and passes to aluminium sheet fast, and the effect of aluminium sheet is to derive the heat of coming to the insulating heat-conductive layer to pass to Lamp cup again.Through heat transfer path repeatedly, can cause radiating effect bad, influence the operate as normal of LED.And the material of insulating heat-conductive layer in the market is single, and the excessive heat radiation process that also has influence on system greatly of the thermal resistance of insulating heat-conduction material gets steady operation thereby influence the LED lamp, hinders the development of high-powered LED lamp.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency that exists in the prior art, and a kind of insulating heat-conductive layer by ceramic material is provided, and in copper foil layer, is provided with the high-efficiency heat-radiating aluminum plate in a hole.
The technical scheme that the utility model adopts is: include aluminium sheet (1), insulating heat-conductive layer (2), copper foil layer (3), electrode (4), seat hole (5); In copper foil layer (3), be provided with the high-efficiency heat-radiating aluminum plate in a hole (5); The material that has overcome the insulating heat-conductive layer is single, the excessive heat radiation process that has influence on system of the thermal resistance of insulating heat-conduction material.Staggered lines is carved with in said aluminium base (1) bottom surface; The low thermal resistance insulating heat-conductive layer (2) that ceramic material is arranged above; The top of insulating heat-conductive layer (2) is copper foil layer (3), is provided with a hole (5) in the copper foil layer (3), and the two ends in seat hole (5) are with matching used two electrodes (4).
The advantage that the utlity model has is: simple in structure, be easy to produce, good heat dissipation effect, can improve service time and the stability thereof of LED greatly.
