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: 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.

Abstract: A lighting device extends substantially along a first axis and comprises a LED light source, which has a substantially hemispheric emission on a side of an emission plane, and an optical group, which is placed in front of the light source; the optical group is configured so as to intercept the light emitted by the light source and generate a light ring, which extends at 360° around the light source on opposite sides of the emission plane and is substantially parallel to a meridian plane, which is perpendicular to the emission plane and goes through the axis of the lighting device.

Abstract: A lighting system comprises at least one plurality of lighting units and at least one joint, connecting two or more units; the joint comprises a central support extending along a first rotation axis and two or more arms, radially projecting from the support and hinged in a rotary manner to the support to rotate with respect to the support about the first rotation axis; each arm is hinged in a rotary manner about a second rotation axis, orthogonal to the first rotation axis to a connection head fixed to a lighting unit.

Abstract: A modular lighting system, comprising at least one module and auxiliary components which can be assembled together; the module comprising a support core, extending along an axis; a plurality of LEDs, arranged on at least one face of the core and axially spaced along the axis; a light body positioned in front of the LEDs and at least partly around the LEDs and having a lighting surface which transmits the light emitted by the LEDs to the surrounding environment; the modules and the auxiliary components are joined to each other by respective concealed mechanical and electrical connection devices, which are completely housed and concealed inside the modules and/or the auxiliary components.

Abstract: A lighting system comprises a plurality of lighting devices interconnected with one another in a communication network, preferably a wireless communication network; the lighting devices define respective equivalent nodes of the network and are configured so that any one of said lighting devices of the lighting system selectively acts as a master, if an initial control input is received directly by that lighting device; and as a slave, if the initial control input is received by another lighting device.

Abstract: A lighting device, in particular a LED lighting device, comprises at least one light source and a reflector extending along and around a longitudinal axis and having an internal reflective surface arranged so as to intercept at least part of the light emitted by the light source and reflect said part towards a light exit opening; the internal reflective surface is a faceted polynomial surface.

Abstract: A LED lighting device comprises a lighting body extending along an axis and internally provided with a chamber housing a LED light source and is delimited by at least one lateral wall consisting of a diffuser having an outer surface defining an emission surface of the device; the diffuser is an opaline diffuser having a transmission coefficient greater than or equal to 50% and a reflection coefficient greater than or equal to 45%.
