The MidNight function feature allows an autonomous dimming without the need for an additional control line. The output levels can be set to 0% (OFF) or between 10% and 100% in steps of 1%
Two different modes for MidNight function are supported:
Time-based: The dimming profile defined in the reference schedule is referenced to the switchon time of the LED driver.
Astro-based: The dimming profile defined in the reference schedule is referenced to the annual average middle of the night, which is calculated based on the theoretical sunrise and sunset times.
