Abstract

L'invention concerne un module à LED (1) comprenant : - des bornes (2) destinées à une section de LED (3); - un circuit (4) qui est conçu pour représenter une charge, de préférence une charge de puissance active lorsqu'une première tension d'alimentation (5a) différente de zéro est appliquée au module à LED (1), qui est dimensionnée de telle sorte que lors de la connexion d'une section de LED celle-ci est non-conductrice, et qui est conçu pour représenter l'absence de charge lorsqu'une seconde tension d'alimentation (5b) différente à zéro est appliquée au module à LED (1), pour laquelle lors de la connexion de la section de LED (3) celle-ci est conductrice et émet de la lumière, le type de variation de charge étant choisi en fonction de la valeur de la première tension d'alimentation et/ou d'une modulation de la première tension d'alimentation.
