LED based lighting and display device, has regulation module regulating real voltage at terminals of LED line such that voltage is maintained less than or equal to reference voltage corresponding to normal voltage of each LED

摘要

The system has an electrical circuit (10) with line conductor tracks (11A-11H) crossing column conductor tracks (12J-12N), where each column track includes LEDs (2) in series to form an LED column (2J-2N). The LEDs of the columns between the line tracks form LED lines (2AB, 2BC, 2CD, 2DE, 2EF, 2FG). A regulation module (3) regulates a real voltage at terminals of a LED line at a power supply state of the circuit such that the voltage is maintained less than or equal to a reference voltage that corresponds to a normal voltage of each LED forming the corresponding LED line.
