FIELD: physics.
SUBSTANCE: lamellar LED screen consists of several LED segments connected in a single surface. Each segment includes a segment frame, several LED lamels and one or more control units. The screen element fixing devices are located in one line on one side of the screen, which greatly simplifies the replacement of LED elements. The screen elements are fixed on the segment frame using the guides and clamps. The guides block movement of the LED elements on two axes, and blocking is performed along the third axis by means of clamps of the longitudinal motion. The clamp of the longitudinal motion consists of a permanent magnet and a core. The permanent magnet holds the clamp on the segment frame, and the core blocks the motion of the LED screen element.
EFFECT: creating a LED screen long up to 10 meters; providing the possibility of a simple and quick replacement of the screen elements behind and in front; simplifying the installation of screen elements by reducing the number of external connecting cables.
