Beschreibung
Zusammenfassung:	An illumination device (1) comprises: mains input terminals (2, 3); a power source (30), having input terminals (31, 32) coupled to the mains input terminals and having three output terminals (33, 35, 34), one of said output terminals being a common output terminal (35). A first output (36) is defined by a first output terminal and said common output terminal; a second output (37) is defined by a second output terminal and said common output terminal. A first LED string (110) is connected to the first power source output in series with a first resistor (120). A second LED string (210) is connected to the second power source output in series with a second resistor (220). The power source is controllable to vary the voltage at the common output terminal within the range from the voltage at the first output terminal to the voltage at the second output terminal.
