LED LUMINOUS-PANEL MODULAR SYSTEM

摘要

The present LED luminous-panel modular system consists of a set of panels (1) of LEDs (2), controlled by intelligent modules (10) connected to a control module (3) via the bus (4), in which the preprogrammed sequence sent from a computing system (5) is displayed, there being an array of equalizing resistors (6) connected in series with each LED of the panels (1), which are connected on the other side to the power supply (7) via a pulse width modulation (PWM) system (9) that regulates the input voltage. The intelligent modules activate the LEDs corresponding to the image to be displayed and control its brightness by means of an internal PWM system (8), thereby providing great flexibility in the production of all types of information panel and minimizing power losses.
