Abstract (en)
The fluorescent light has a LED module on which two LEDs (1) are arranged with series or parallel connection in two-dimensional array. The LEDs are connected with a resistor (2) and a switch (3) such that the change of the lights of the LEDs is possible. A constant current source is provided for supplying current to the LEDs. A control unit is provided to control the switch. The white LEDs and multi-color LEDs are used.
