Optical signal output of operating parameters with an LED lighting unit

摘要

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.

主权项

1. A method for the optical signal output of operating parameters in an operating device (3) with an LED light source (4) which is controlled by said operating device and is formed by at least two non-white LEDs (4a, 4b, 4c), which individually are configured to emit non-white light of different colors and together provide lighting by emitting white total light, wherein the method comprises the steps of:
selecting one or more of the non-white LEDs (4a, 4b, 4c) forming the LED light source (4) that are configured to emit the non-white light; and driving these one or more selected non-white LEDs to provide a diagnostic optical signal output comprising emitted non-white light indicating operating parameters of the operating device.
