High brightness solid luminous subassembly manufacture method and luminous subassembly

Abstract

The invention discloses a method for manufacturing a solid luminescent component with high brightness, which comprises the following steps: (1) a luminescent unit which can generate light is formed on a base plate; (2) a transparent coarsening unit is formed on the outer surface of the base plate by transparent material covering; (3) a selective etching liquid medicine is prepared and the transparent coarsening unit is immerged in the liquid medicine; (4) the outer surface of the transparent coarsening unit is bombarded by plasma beam so that concavo convex is formed on the outer surface; (5) a P type electrode which has an orme contact with a P type batch coating is formed on the reserved location of the upward of the transparent coarsening layer; (6) an N type electrode which has an orme contact with an N type batch coating is formed on the reserved location of the N type batch coating. The invention also discloses a luminescent component by adopting the method, which comprises an insulating base plate; a luminescent component arranged on the baseboard; a transparent coarsening unit with concavo convex state out surface. The invention has a better refraction effect and a higher external luminescent efficiency.

Description

Technical field [0001] The invention relates to the manufacturing technology of solid-state light-emitting components, in particular to a method for manufacturing high-brightness solid-state light-emitting components by selective etching solution and plasma beam bombardment, and the light-emitting components. Background technique [0002] For the manufacturing method of high-brightness solid-state light-emitting components in the prior art, in the published patent literature, the Taiwan patent application publication number is 200536139, the application date is April 26, 2004, and the title of the invention is "Manufacturing of high-brightness solid-state light-emitting components The patent application of "Methods and Products" discloses a method for manufacturing a high-brightness solid-state light-emitting component and its products, which are mainly to randomly arrange a plurality of spaced masking blocks on a transparent roughening unit, and the plurality of spaced apart mas...

AI Technical Summary

Problems solved by technology

Its disadvantages are: 1. It needs at least the process of forming a masking block, etching, and removing the masking block on the transparent roughening unit before it can achieve the desired effect and produce the product, and there must be a photoresist in this process. 2. The concave area obtained by it is always lower than the upper surface of the transparent roughening unit, and the refraction effect produced by it still needs to be improved
