Abstract:
1. A method for manufacturing a light-emitting diode having a high heat-dissipating efficiency, comprising the steps of: a) preparing a thickened metal; b) forming the thickened metal into a support having a first electrode and a second electrode, wherein the first electrode has a supporting portion with a trough, the first electrode and the trough are integrally formed in this step; wherein the supporting portion of the first electrode formed in the step b) further has a plurality of penetrating holes, one end of the supporting portion is connected with a conductive pin; c) applying a layer of adhesive on the trough of the first electrode; d) adhering the chip on the adhesive; e) welding two leads on the chip, and electrically connecting one end of each of the two leads to the first and second electrodes respectively; f) dotting glue on the chip, the first electrode, the second electrode, adhesive, leads and the support; and g) forming a thin seat and lens having a packaged chip, adhesive, leads and support by means of a hot press-forming process.
