Abstract

The invention relates to an LED (Light-Emitting Diode) light-emitting element. The LED light-emitting element comprises LED chips and a glass substrate, wherein the LED chips and a metal conductive circuit are fixed on the glass substrate; the connecting surfaces of the glass substrate and the LED chips are coated with aluminum nitride coatings, and the LED chips are coated with fluorescent powder adhesives; a plurality of the LED chips are connected in series and arranged on thin-film circuits of the aluminum nitride coatings in a solid-phase crystallization way; the surfaces of the LED chips are coated with fluorescent powder so that white-light devices are formed; aluminum nitride coating thin-films are grown on the glass substrate in a magnetron sputtering film-forming way; and fluorescent powder adhesive protective layers coated at the outer layers of the LED chips can be formed into needed shapes according to the light-emitting shapes of the LED chips. The LED light-emitting element disclosed by the invention increases the radiating area by coating the aluminum nitride coating thin-films as heat-conducting insulated layers on the LED chips and the glass substrate, thereby realizing optimal radiation.

Description

technical field [0001] The invention relates to an LED light-emitting component, in particular to an LED light-emitting component provided with a heat-conducting insulating layer on an LED chip and a glass substrate. Background technique [0002] LED is a light-emitting diode (LED, Lighting emitted diode), which is a solid-state light-emitting device that uses the PN junction to emit light under the action of an electric field. With the characteristics of high life / environmental protection / energy saving, it is a new green light source. [0003] LED technology is becoming more and more mature. At present, LED white light is white light produced by exciting yellow-green phosphors through blue chips and reconciling wavelengths. At present, the luminous efficiency of LEDs has exceeded most traditional light sources. Generally speaking, LED grows a PN layer and a light-emitting layer on an epitaxial wafer through MOCVD (Metal-organic Chemical Vapor Deposition), and then makes it...
