Abstract (en)
[origin: EP1992542A2] The arrangement has two strands of high performance-LEDs (32, 34) connected in series, where the LEDs are arranged on a common circuit board such that the LEDs of one strand produce same light distribution as the LEDs of the other strand. The strands separated from each other are supplied with current to activate the LEDs in the respective strands. A monitoring unit monitors current flowing in the strands and voltage flowing to the strands. A control unit is provided for automatic change over to another strand during failure of the working strand or the LED of the working strand. An independent claim is also included for a method for operating an LED arrangement.
