Abstract
A light emitting diode (LED) disc lamp includes a lamp base, a plurality of LED modules on the lamp base and a lampshade to cover the lamp base. The lamp base is made of aluminum. The lamp base includes a bottom plate which is integrally formed with a circular trough by stamping. The circular trough has a circumferential wall and a bottom which are formed with a plurality of apertures. Each of the plurality of LED modules includes a heat sink fin which is disposed in the circular trough of the lamp base. The LED modules can be replaced with ease. The heat generated from the LED modules can be radiated effectively. The height of the disc lamp can be reduced to beautify the disc lamp.
