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 he directly mounted on the light-scattering plate. The number of LED is determined by the brightness of the lighting lamp tube. The lamp caps and the electrode pins possess the same international standards as common lamp tubes. An alternate current flows into the converter through electrode pins and is converted into a direct current, which will be supplied for LED. The transparent tube body can be made of transparent or translucent materials, and the tube body can he processed to have a convex-concave inner surface to facilitate scattering of light. The LED lighting lamp tube can directly substitute fluorescent tubes and lamp tubes for other lighting or decoration, which are used nowadays. |
