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.
