A lighting group (1, 10), comprising: a frame (2); a support (3) which is constrained to the frame (2); a photovoltaic cell (4) which is constrained to the support (3); an artificial light source (5). In particular, the support (3) is provided with a reflective surface (6) arranged and conformed such as to convey solar rays (R) towards the photovoltaic cell (4); the artificial light source (5) is constrained to the support (3) such as to emit a light beam (50) which reflects against the reflective surface (6) and propagates towards the outside; the support (3) is rotatable about an axis such as to be arranged such as to maximise a quantity of solar rays (R) which reflect against the reflective surface (6) and are conveyed towards the photovoltaic cell (4) and in order to regulate the direction of the light beam (50) emitted outwards from the artificial light source (5). |
