Abstract
An LED tube has a tube body, an LED light board and two caps. The tube body has a translucent tube shell and a heat dissipating seat. The translucent tube shell has two openings and a gap. The heat dissipating seat is mounted in the gap. The LED light board is mounted in the tube body and has a luminous surface, wherein two opposite ends of the LED light board extend out of the heat dissipating seat. The luminous surface has four electrical connecting parts, wherein each two electrical connecting parts are respectively mounted near a corresponding one of the two opposite ends, thus, the four electrical connecting parts are mounted away from the heat dissipating seat to extend internal creepage distances between the four electrical connecting parts and the heat dissipating seat, and further increase electrical safety of the LED tube.
