Abstract
A method and a lighting control system for automatically determining a calibration curve for use in daylight harvesting applications. The lighting control system comprises a light sensor configured for recording light levels and a load controller configured for provide a dimmed output to a lighting load. The calibration curve comprises a calibration slope (S) defined by a calibration coordinate (C) and a night coordinate (C). The calibration coordinate (C) comprises a calibration dimming level (D) set by a user and a calibration light level (L) recorded by the light sensor when the lighting load is set to the calibration dimming level (D). The night coordinate (C) comprises a night scene dimming level (D) and a night scene light level (L), wherein the night scene light level (L) comprises a difference between a sunlight plus night scene light level (L) recorded by the light sensor when the lighting load is set to the night scene dimming level (D) and a sunlight level (L) recorded by the light sensor when the lighting load is turned off.
