Problems solved by technology

Furthermore, the present invention uses an adhesive layer to bond the light-emitting laminate with the micro-reflector to the surface of the substrate, instead of only relying on the top of the reflector to be partially bonded to the carrier as in the aforementioned known technology, so that the structure can be solved. The disadvantage that the mechanical strength is not strong enough

Abstract

A light-emitting component with a micro-reflector reflects the light emitted to the micro-reflector from a luminous layer first then derives it out to increase the luminescence efficiency of the component.

Description

technical field [0001] The invention relates to a light-emitting component, in particular to a light-emitting component with a micro-reflector. [0002] Light-emitting components are widely used, for example, in optical display devices, laser diodes, traffic signals, information storage devices, communication devices, lighting devices, and medical devices. In this technology, one of the important tasks for technicians at present is how to improve the luminous efficiency of the light-emitting component. Background technique [0003] In U.S. Patent Publication No. 2002 / 0017652, an AlGaInP light-emitting device with a buried micro-reflective structure is disclosed, such as figure 1 As shown, it uses etching technology to etch the epitaxial layer of the light-emitting component into a micro-reflective structure epitaxial layer 41. The micro-reflective structure includes a hemispherical, pyramidal or pyramidal shape, etc., and then deposits a metal reflective layer 42 on the epi...
