Abstract

A light emitting diode lamp includes multiple LED members, a plane circuit board, an LED fixing cover, a circuit board mounting seat, a drive circuit, and an LED lamp base having a bulb copper head. The plane circuit board is initially cut to form a multiple-ring shape. Then, the multiple LED members are arranged and soldered on the plane circuit board. Then, the circuit board mounting seat is mounted on the bottom of the plane circuit board, thereby forming a spatial shape having a convex arcuate face. Then, the plane circuit board and the circuit board mounting seat are mounted in the LED lamp base. Then, the LED fixing cover is mounted on the LED lamp base, thereby assembling the light emitting diode lamp which may be available for the present filament bulb seat.
