    Abstract: A light-emitting diode structure and a method for manufacturing the light-emitting diode structure. The method includes steps of: preparing a metal plane blank in a production line and punching the blank with an upper mold section to form a concave central section protruding from the blank; punching the concave central section with a lower mold section in a reverse direction, whereby a bottom of the central section is formed with at least one rigid wall defining a cavity; pressing a predetermined position of the central section with another upper mold section in a direction the same as the moving direction of the upper mold section to form a bowl seat on the central section for fixing a chip in the bowl seat; and forming a grid structure on a periphery of the central section so as to complete a model body. The model body has a central section and a connecting section. The central section has a bowl seat for fixing therein a chip. The central section is defined as a cathode end.
