    摘要： A control method is provided for controlling a lighting system for automatically adjusting the colour temperature of the lighting system, by adjusting the colour temperature of the light emitted by the lighting system during one day according to a pre-set daily emission profile; the colour temperature emitted by the lighting system is progressively adjusted during the day according to a daily emission profile represented by a spline function consisting of a plurality of spline function portions corresponding to respective pre-set time periods; the daily emission profile is, moreover, modified based on a geographic position and, in particular, a latitude of the lighting system being controlled, as well as on the current date.

    摘要： A multi-function lighting apparatus (1) comprising a support structure (2), a light engine (3) mounted on the structure (2), and a control unit (4) controlling the light engine (3); the light engine (3) comprising a first group of warm LEDs (6) having color temperature ranging between 2000 and 2500 K and color rendering index (CRI) ranging between 85 and 95; and a second group of cold LEDs (7) having color temperature of at least 5000 K and color rendering index (CRI) ranging between 65 and 75; the control unit (4) being a two-channel driver control unit which controls independently the warm LEDs (6) and the cold LEDs (7) and is configured to control the light engine (3) to emit white light with variable color temperature and luminous flux according to at least three different modes performing a lighting function, a plant maintenance function, and a sanification function respectively, as the color temperature and the luminous flux emitted by the light engine (3) vary.
