Abstract

An LED light bulb (10), comprising: a head portion (14); an insulation tube (16), with its bottom end screw-locked onto the head portion, and with its inside provided with a driver-circuit-board component (20) having its one end connected electrically to said head portion; a heat dissipation cup (22), disposed on said insulation tube, inner and outer surfaces of said heat dissipation cup are provided with indent-protrusion texture structures (21), and its bottom surface is provided with two conduction-wire through-holes (24); an LED circuit board (27), and at least a Hi-Power LED (26) is provided thereon, and said LED circuit board is disposed on said bottom surface of said heat dissipation cup (22), said LED circuit board (27) is connected electrically to an other end of said driver-circuit-board component (20); and a hood (30), provided on a top end of said heat dissipation cup. The indent-protrusion texture structures on said heat dissipation cup are capable of dissipating speedily heat generated by the LED.
