An LED lighting device, extending along a longitudinal axis and having a circular shape about the axis, comprises an LED holder plate, having a front face which supports a plurality of LEDs; an optical element positioned in front of the front face of the LED holder plate and having a plurality of lenses aligned with and facing respective LEDs; and a grid positioned in front of the optical element on the opposite side of the LED holder plate and having a plurality of hexagonal cells which are arranged in a honeycomb pattern and which are aligned with and facing respective lenses of the optical element.

LED lighting device with honeycomb grid

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.

Multi-function lighting apparatus

A lighting system comprises a support cable having two conductive wires only; a plurality of fastening elements for supporting the cable along a path; a plurality of coupling elements fixable to the cable and having respective pairs of contacts which draw current from the cable; and a plurality of lighting devices coupled to respective coupling elements; each fastening element is provided with a printed circuit board, connected to the contacts and to the lighting device coupled to the fastening element and comprising a DC converter; a dimmer; and a Bluetooth module for receiving and processing signals from an external control device; the board is configured to receive current from the cable and generate a dimmed direct current which supplies the lighting device connected to the board.

Lighting system

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.

Method for controlling a lighting system

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.
