Abstract
An electronic device is for identifying a LED driver which is a switched mode power supply. For example the LED driver is part of an LED luminaire. An interface () is adapted to be coupled to a high frequency power commutation component of the switched mode power supply, for sensing the high frequency power commutation of the switched mode power supply in driving the LED. A mapping is made between identifications of LED drivers which are switched mode power supply and characteristics of the high frequency power commutations in driving the LED of a respective switched mode power supply. Thus, a LED driver which uses a switched mode power supply can be identified corresponding to extracted characteristics of the high frequency power commutations in driving the LED. This identification can be used for energy monitoring and fault diagnosis purposes, for use in a universal low cost LED driver.
