Abstract:
1. A method for auto commissioning a light emitting diode (LED) lighting system to provide feedback to a technician when the LEDs require servicing; the technician providing a command to a control module causing: (i) the lighting system to turn on and remain on for a sufficient period of time; (ii) an algorithm to run a capture routine causing at least one light sensor to provide frequent readings of light levels from the lighting system to determine the lowest light level (lmin) over the sufficient period of time; (iii) the control module analyzing the readings to select and store the lowest level reading in a non volatile memory device; (iv) the algorithm setting a timer to repeat the capture routine at repeated intervals of time and, if a lower value for lmin is found, to replace the previously stored value in the non volatile memory device, (v) after the algorithm repeats the capture routine at repeated intervals for a specified time, the capture routines will stop, and the lowest value of lmin will remain in long term memory; (vi) periodically thereafter, the light level being measured and compared with lmin to determine if the system requires servicing and, if criteria are met, providing a signal to the technician.
