Abstract: An installation such as, for example, a box or cabinet for horticultural applications includes a lighting space between a lighted plane and a lighting plane parallel to the lighted plane, with side walls that are at least partly light-reflective. The illuminated plane may be defined by the upper surface of a plant culture medium. A set of light radiation sources, e.g. LEDs, arranged centrally relative to the lighting plane projects light radiation towards the lighted plane in the direction of a radiation emission axis. The set of light radiation sources emits light radiation with a distribution of illuminance projected towards the lighted plane, wherein the lighted plane is non-uniform and gradually decreases as a function of the angle relative to the aforesaid radiation emission axis, wherein the reflection of the radiation on the side walls facilitates uniform illuminance at the lighted plane.

Abstract: A lighting device may have a planar array of electrically-powered light radiation sources partitioned into a plurality of sets of light radiation sources. The light radiation sources of the same set may emit light radiation of the same color, and different sets of radiation sources may emit light radiation of different colors. Each one of the different sets of light radiation sources may include a respective fraction of the total number of light radiation sources in the array. The light radiation sources have respective planar coordinates relative to a common center of the array, and the different sets of light radiation sources have respective centers located at the common center. The array comprises at least two complementary sub-arrays, opposite to the common center. The different sets of radiation sources are present in the sub-arrays in respective partial fractions of the number of radiation sources included in the sub-array.
