Abstract

The invention discloses a LED and a manufacturing method thereof. The LED at least comprises: a conductive substrate with oppositely a first and a second surfaces; a reflection structure at least comprising a conductive reflection layer jointed on the conductive substrate, and a conductive dispersed Bragg reflection structure overlapped on the conductive reflection layer; a light emitting epitaxial structure arranged on the reflection structure; a first electrode arranged on part of the light emitting epitaxial structure; and a second electrode jointed with the second surface of the conductive substrate.

Description

technical field [0001] The present invention relates to a photoelectric element and its manufacturing method, and in particular to a light emitting diode and its manufacturing method. Background technique [0002] Semiconductor light-emitting elements, such as light-emitting diodes, are elements made of semiconductor materials, which are tiny solid-state light sources that can convert electrical energy into light energy. Because this kind of semiconductor light-emitting element is not only small in size, but also has the characteristics of low driving voltage, fast response rate, shock resistance, and long life, and can meet the needs of various application equipment for lightness, thinness, shortness, and smallness. Optoelectronic components that are quite common in life. [0003] At present, a fairly common method for increasing the light output of a light-emitting diode is by increasing the light extraction rate of the light-emitting diode. There are roughly the followi...
