Abstract: A multi-function lighting apparatus comprising a support structure, a light engine mounted on the structure, and a control unit controlling the light engine; the light engine comprising a first group of warm LEDs having color temperature ranging between 2000 and 2500 K and color rendering index ranging between 85 and 95; and a second group of cold LEDs having color temperature of at least 5000 K and color rendering index ranging between 65 and 75; the control unit being a two-channel driver control unit which controls independently the warm LEDs and the cold LEDs and is configured to control the light engine 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 vary.

Abstract: An LED lamp, in particular a table lamp, comprises a lighting head extending about a central axis; the head comprises: a body shaped as a ring about the axis and provided with a substantially annular seat; a plurality of LEDs arranged spaced apart from one another along the seat and about the axis and supported by a printed circuit board positioned in the seat and having a face, on which the LEDs are positioned, perpendicular to the axis; and a lens positioned in front of the LEDs to close the seat; the lens consists of a monolithic piece extending about the axis and has a concave annular inlet surface, facing the LEDs, and a convex annular outlet surface, substantially aligned parallel to the axis and extending about the axis and shaped so as to generate a rotosimmetric light emission about the axis.

Abstract: 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.
