Abstract
Official abstract text for this publication.
The application discloses a method and apparatus for providing a desired warning signal for a lighting unit. A coded warning system is provided employing a detection module ( 320 ) and a signal generating module ( 330 ), wherein the detection module is configured to obtain information regarding the detection of one or more operating parameters of the lighting unit and the signal generating module generates a desired warning signal ( 331 ) selected from a plurality of warning signals, upon determination that one or more of the operating parameters are abnormal operating parameters. Each warning signal of the plurality of warning signals is indicative of a specific abnormal operating parameter or a known combination of specific abnormal operating parameters.
