Abstract:
1. A method for manufacturing an integrally formed multi-layer light-emitting device, comprising the following steps: preparing a seat including a central main body and a plurality of heat dissipation fins, a central portion of the central main body having two through holes longitudinally formed therein; milling a bottom of the central main body to form a first chamber having an accommodating space concaved inwardly, a top of the central main body being milled to form a second chamber having an accommodating space concaved inwardly, the second chamber including a bottom and an inclined inner sidewall, the two through holes each being milled to form a step at one end near the second chamber; arranging two connection pieces in the two through holes, respectively, each connection piece including a conductive rod and a sleeve for inserting the conductive rod therein, two ends of each conductive rod being extended out of the sleeve, each conductive rod having a flange on one end near the second chamber, the flange being placed on the step; arranging two fixing pieces in the two through holes, respectively, so that the two connection pieces are fixed in the seat; selectively electroplating a first reflective layer onto an area of the seat; arranging a plurality of light-emitting elements on the bottom; electrically connecting the light-emitting elements with one ends of the two connection pieces by wire-bonding with use of metal wires; and arranging a lens mask on the second chamber, so that the seat is sealed by the lens mask.
