INTERFACE CIRCUIT

An interface circuit is disclosed for operating a light source from an electronic fluorescent driver. In one example, the interface circuit comprises input terminals for connection to lamp connection terminals of the electronic fluorescent lamp driver, a first string interconnecting a first pair of input terminals, a second string interconnecting a second pair of input terminals, a third string interconnecting a first terminal of the first string and a second terminal of the second string and comprising a rectifier, output terminals of said rectifier being coupled during operation to the light source. When a light source is operated making use of the interface circuit, a proper emulation of a fluorescent lamp is obtained.
