FIELD: image forming devices.SUBSTANCE: invention relates to devices for presenting varying information material and can be used for creation of external video display devices. Inventions are aimed at solving task of creating a new type of light-emitting diode video screens, consisting of a set of long (up to 10 metres) light-emitting diode segments. Said screens will have low weight, easy assembly and maintenance. Device consists of a waterproof profile, transparent waterproof film and a set of perforated covers. LED modules are placed on surface of waterproof profile. On front profile with LED modules is covered with transparent waterproof film, which is glued on each side of profile using waterproof glue. Therefore, a continuous waterproof cover is formed around group of LED modules. On front, film is fitted with perforated covers, holes of which are located opposite light-emitting diodes of LED modules. Perforated covers are fixed on surface of LED modules by means of latches, which cover waterproof profile on both sides.EFFECT: invention is intended to create waterproof LED lamellae for street light-emitting diode video screens.20 cl, 11 dwg |
