| description | The present invention comprises a street light control system characterized by comprising: a lighting unit in which a plurality of LED modules are connected in parallel; a power supply unit supplying power to the lighting unit; and a current equalization control unit which senses the current value of each LED module and adjusts the current value by means of PWM control of a LED module having a deviation from an average current value or a set current value so as to control the LED modules to maintain a uniform current value, wherein the lighting unit includes a switching element for switching power lines of the LED modules, and the current equalization control unit controls the switching element by varying a duty ratio according to the deviation of the current value.
La présente invention comprend un système de commande de réverbère caractérisé en ce qu'il comprend : une unité d'éclairage dans laquelle une pluralité de modules de DEL sont connectés en parallèle ; une unité d'alimentation électrique fournissant de l'énergie à l'unité d'éclairage ; et une unité de commande d'égalisation de courant qui détecte la valeur de courant de chaque module de DEL et règle la valeur de courant au moyen d'une commande PWM d'un module de DEL ayant un écart par rapport à une valeur de courant moyenne ou une valeur de courant définie de façon à commander les modules de DEL pour maintenir une valeur de courant uniforme, l'unité d'éclairage comprenant un élément de commutation pour commuter des lignes d'alimentation des modules de DEL, et l'unité de commande d'égalisation de courant commandant l'élément de commutation en faisant varier un rapport cyclique en fonction de l'écart de la valeur de courant.
