Abstract
A lighting device includes a cover, a cap, a central post having opposite ends coupled to the cover and the cap respectively, and a plurality of first and second frames. The cover and the cap both form a plurality of circumferentially distributed slots opposite to each other. The first and second frames have ends respectively fit into the slots of the cover and the cap and each frame carries at least one light-emitting diode. As such, a light-emitting diode lighting device that is hollow, light-weighted, and exhibiting excellent heat dissipation is formed.
