Abstract (en)
A Led module (1) comprises at least one Led (4) and a current controller (5) which regulates the current delivered to the Led (4), so that said controller (5) sets the intervals of time in which the Led (4) is conducting current. A Led-based lightning system comprises at least a first controller (3) and at least one of said Led modules (1), whose controller (5) is then a second controller, and a data connection between the first controller (3) and the Led module (1), through which a modulation signal generated by said first controller (3) is transmitted to the associated second controller (5).
