Abstract
A LED lighting lamp tube comprises a transparent tube body, lamp caps, electrode pins, pedestals mounted at the connection position of the transparent tube body and the lamp caps, a power supply converter located adjacent to the lamp caps and inside the tube body, a PCB and a plurality of LED mounted on the PCB. These LED are connected in parallel or in series, and a light-scattering plate may be disposed over these LED. A plurality of LED chips can be directly mounted on the light-scattering plate. The lamp caps and the electrode pins possess the same international standards as common lamp tubes.
