Abstract: A high efficient tubular light emitting cylinder is disclosed. The high efficient tubular light emitting cylinder is especially an LED tubular light emitting cylinder which can be installed and maintained easily and has a high light emitting efficiency. The tubular light emitting cylinder has a plurality of light emitting segments. The light emitting segments are connected in series. The connected light emitting segments are installed in a tubular light emitting cylinder for improving the light emitting efficiency. The light emitting segments can be taken out from the light emitting cylinder easily so that the light emitting cylinder can be installed and maintained easily and conveniently.

Abstract: An LED tubular lighting device and control device includes LEDs planted in a transparent tube and controllable via a controller to obtain multifarious light sources. The tubular lighting device includes LEDs soldered onto a circuit board in an equi-distant arrangement. The circuit board with the LEDs is secured in a boat-shaped receiving, heat-dissipating trough, which are disposed in a transparent tube having heat-dissipating holes in the bottom wall thereof and through holes in both ends thereof. The LED tubular lighting devices can be connected in series and controllable to produce changes in colors and luminosity.

Abstract: A matrix type LED wall display tube device is adapted for mounting on a wall, and includes equidistantly spaced apart LEDs soldered onto circuit boards and disposed inside transparent tubes to form serially connected display tubes. The display tubes are spaced apart and secured in juxtaposition by means of interconnected bases. A programmable controller is used to achieve LED signal displays to therbey provide a display device with advantages of good displaying effects, easy installation and low costs.
