Abstract (en)
[origin: WO2010000349A1] The invention relates to detecting a lamp type and setting of operating parameters for operating luminous elements depending on the type of luminous element detected, comprising the following steps: Constant regulating of the power fed to the luminous element, - detecting the voltage drop across the burning luminous element at constant power or the current flowing through the luminous element, and - selecting at least one operating parameter as a function of the voltage drop.
