Patent ID: 7438441

Claim:
A light emitting Diode (LED) light tube applied to be directly assembled to two pairs of electrode insertion holes of a fluorescent light tube fixture to replace a fluorescent light tube for projecting an illumination light beam, and comprising: a heat-dissipating base extended along an extension direction, and comprising: a base body substantially composed of a heat-conductive material, and having an arrangement surface, a first peripheral-surface and two first end-surfaces; two pairs of electrode contacts respectively protruded from the two first end-surfaces for assembling to the two pairs of electrode insertion holes; and a plurality of heat-dissipating grooves formed on the first peripheral surface for dissipating a lighting heat generated when projecting the illumination light beam; a plurality of linear-extended LEDs arranged on the arrangement surface; and a light-transmissible shell extended along the extension direction, matching to the heat-dissipating base, and having an opening for assembling to the arrangement surface to package the plurality of linear-extend LEDs with the heat-dissipating base.
