Problems solved by technology

Furthermore, the present invention uses a transparent adhesive layer to bond the micro-reflective structure layer and the surface of the light-emitting stack together, instead of only relying on the top of the reflector to be partially bonded to the carrier as in the aforementioned known technology, so it can solve the problem of the structure. Disadvantages of insufficient mechanical strength

Embodiment Construction

[0058]Please refer to FIG. 2 , according to a preferred embodiment of the present invention, a light-emitting component 1 with a microreflective structure layer includes a substrate 10 and a microreflective structure layer 11 formed on the substrate 10. The microreflective structure layer is formed by die-casting technology. , using a master mold with a predetermined pattern to die-cast the metal reflective layer into a micro-reflection structure layer, wherein the predetermined pattern of the master mold includes geometric patterns such as raised hemispheres, pyramids, or pyramids, or combinations thereof, and the master mold The production method is to plate a layer of polymer material on the carrier, such as polyimide, and then use etching technology to initially etch the layer of polymer material into the aforementioned predetermined pattern, or perform a heating process after etching to The etched pattern, such as a rectangle, becomes a raised hemispherical shape after the...

Abstract

A luminous component with a micro-reflection structure layer derives the light emitted to said reflection structure layer by the emit layer to increase the radiation efficiency of the light emit component.

Description

technical field [0001] The invention relates to a light-emitting component, in particular to a light-emitting component with a micro-reflection structure layer. [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, the micro-reflective structure includes a hemispherical, pyramidal or pyramidal shape, etc., and then deposits a metal reflective layer on the epitaxia...
