摘要： A Light Emitting Diode (LED) light tube includes a heat dissipation base having a light emitting side formed with a recess and at least one illumination unit and a bridging unit disposed on a bottom surface of the recess. The illumination unit and the bridging unit are connected electrically relative to each other via wire-bond technique. Two circuit units are disposed on the light emitting side of the heat dissipation base respectively located at two opposite sides of the recess.
