A street light having a hollow pole is provided with a lower hand-access opening closed by a hatch (3). The hollow pole (1) has an internal surface and an external surface, its external surface being lined by external photovoltaic cells (14) in an upper section thereof, and a lamp (6) that is positioned inside the hollow pole (1). The upper end of the hollow pole (1) is open and the lamp (6) is mounted on positioning means so that the lamp can be moved, inside the hollow pole (1), from the lower hand-access opening until near the upper end of the hollow pole (1) on which a tiltable screen (11) is mounted having a side facing upward and a side facing downward, the latter being lined by a reflecting panel (13), the internal surface of the hollow pole (1) being covered by internal photovoltaic cells (14).
