Abstract
The invention relates to a lighting arrangement with an operating device (3) and with an LED light source (4) which is controlled by said operating device and which is formed by at least two LEDs (4a, 4b, 4c), which emit light of different colors and together emit a white total light. The operating device (3) drives some of the LEDs (4a, 4b, 4c) forming the LED light source (4) which are intended to emit monochromatic (non-white) light in such a way that said LEDs emit light signals representing certain operating parameters.
