Abstract
The utility model discloses an aluminum substrate without thermal resistance. The aluminum substrate comprises copper foil, a heat conducting insulating layer, and an aluminum substrate. The aluminum substrate is arranged at the bottom while the copper foil is arranged on the heat conducting insulating layer arranged on the aluminum substrate. A seat hole used for mounting a LED is arranged on the copper foil and the heat conducting insulating layer corresponding to the copper foil. Two electrodes used with the LED are mounted on surface of the copper foil on two sides of the seat hole. With simple structure and good heat dissipating performance, the aluminum substrate without thermal resistance substantially increases operating stability of the LED.
Description
Technical field
The utility model belongs to field of semiconductor illumination, more specifically to a kind of without thermal resistant aluminum-based plate.
Background technology
Existing aluminium base is comprised of three layers of Copper Foil, heat conductive insulating layer and aluminium sheets, the heat conductive insulating layer is that the heat that LED produces is passed to aluminium sheet fast, aluminium sheet is the heat conductive insulating layer to be derived the heat that comes pass to again Lamp cup, existing LED is installed on the Copper Foil, the caloric requirement of its generation is passed to the heat conductive insulating layer by Copper Foil, passes to aluminium sheet by the heat conductive insulating layer again, and heat transfer path is too much, cause the loose effect of heat bad, affect the stability of LED work.
The utility model content
The purpose of this utility model is exactly in order to remedy the deficiency of conventional art, to aim to provide a kind of without thermal resistant aluminum-based plate.This aluminium base can directly be passed to aluminium sheet to the heat that LED produces, and need not through the transmission of heat conductive insulating layer, reduces thermal resistance, improves the loose effect of thermal effect of LED, improves the stability of LED work.
The utility model is achieved by the following technical programs.
The utility model is without thermal resistant aluminum-based plate, comprise Copper Foil, heat conductive insulating layer and aluminium sheet, the bottom is described aluminium sheet, it is described heat conductive insulating layer above the described aluminium sheet, be described Copper Foil above the described heat conductive insulating layer, be provided with the seat hole of installing for LED at described Copper Foil and corresponding described heat conductive insulating layer place thereof, the surface of the described Copper Foil of seat both sides, hole is provided with matching used two electrodes with LED.
The utility model is compared with conventional art and had the following advantages: simple in structure, good heat dissipation effect can improve the stability of LED work greatly.
