Completely-metal integrated illuminating and backlight LED heat radiating structural body

Abstract

The invention discloses a completely-metal integrated illuminating and backlight LED heat radiating structural body which comprises a lamp holder, a lamp cup body, a circuit board provided with an LED, and a lamp shade, wherein the lamp holder is fixedly connected with one end of the lamp cup body through an insulation plastic shell, the lamp shade is fixedly connected with the other end of the lamp cup body, the circuit board is connected to the lamp cup body, the lamp cup body is an integrated structure made of an aluminum material; an aluminum foil or aluminum plate layer is arranged on one surface in the circuit board, which is connected with the lamp cup body, the outer side surface of the aluminum foil or aluminum plate layer is plated with a first metal coating; one surface in the lamp cup body, which is connected with the circuit board is provided with an aluminum installing surface, the outer side surface of the aluminum installing surface is plated with a second metal coating; and the first metal plating layer of the aluminum foil or aluminum plate layer of the circuit board is welded and fixed with the second metal coating of the lamp cup body. The invention realizes a completely-metal integrated structure, greatly improves the heat radiation of the LED lamp and ensures that the heating temperature of the LED lamp is effectively controlled.

Description

technical field [0001] The invention relates to an LED heat dissipation structure, in particular to an LED heat dissipation structure capable of realizing complete metal integration for lighting and backlight. Background technique [0002] At present, with the shrinking size of LED lamps and the increasing power of LED lamps, the heat generated by LED lamps is increasing, and the heat generated by LED lamps will affect their light and service life. For example, when the LED is overheated, its light will become darker, its color will become lighter, and at the same time, its service life will be shortened accordingly. Therefore, the design of the overall heat dissipation structure of LED lighting is very important. [0003] In the prior art, between the lamp cup body of the LED lamp and its circuit board, thermal paste is generally used to achieve mutual affixation, but because the thermal conductivity of the polymer material of the thermal paste is too low (only 0.01-0.1w / m...
