FIELD: electronics.
SUBSTANCE: invention relates to devices for presenting varying information material and can be used for creation of external video display devices. Light-emitting diode bar arrangement consists of one or more light-emitting diode modules, wherein device housing represents external current-conducting section, containing one or more slots to receive inner current conducting sections, insulated from external current-conducting sections by means of electrically insulating layer, inner and outer current-conducting sections serve as electric current conductors for light-emitting diode modules power supply, light-emitting diode modules represent printed-circuit boards with light-emitting diodes located in front, behind on light-emitting diode modules printed circuit boards power supply contact pads are located, arranged into longitudinal straight lines, light-emitting diode modules are connected to each other by means of adapters, light-emitting diode modules are in series arranged on external current-conducting section surface so, that power supply contact pads of separate light-emitting diode modules form line of contacts, which are in contact with current-conducting sections contact surfaces, in front light-emitting diode bar with light-emitting diode modules is covered with transparent waterproof film, glued on each side of external current-conducting section, on light-emitting diode bar perforated covers are installed above transparent waterproof film, which holes are located opposite to light-emitting diode modules light-emitting diodes, perforated covers are fixed on light-emitting diode bar surface by means of side latches, which cover outer conducting section on both sides.
EFFECT: technical result is reduction of light-emitting diode bar weight, simplification of assembly and servicing.
