A light emitting diode lamp includes a light source and a heat radiating device combined with the light source. The light source includes a hollow substrate that is made of metal and has a substantially arcuate shape, a plurality of light emitting diodes mounted on an outer wall of the substrate, a plurality of heat conducting fins mounted on an inner wall of the substrate, and a light permeable cover mounted on the outer wall of the substrate to cover the light emitting diodes. Thus, the substrate of the light source is a substantially spherical body so that the light emitting diodes mounted on the outer wall of the substrate emit light beams outwardly in an irradiating manner and have a larger lighting angle to enhance the lighting effect. |
