NOVELTY - The invention relates to a floor standard lamp with LEDs, with solar battery and optimizer of the electric power provided thereby. According to the invention, the floor standard lamp comprises a part in the shape of a tray-like support (1) with a fixing pipe (a) at its base, a cylindrical electric lamp (C) consisting of a plastic support cylinder (17) with LEDs (I) which are in series, in parallel or series-parallel interconnected and a module (E) for electrically supplying the electric lamp (C) having, as a fixing support, a square-shaped cover (3) mounted on a transparent plastic or glass body (2), including a photovoltaic battery (4) placed between the end parts (b) of the cover (3), some rechargeable batteries (13, 13') and a photoelectric switch (14) which switches off the supply of the electric lamp ( C) when light is detected. The electric supply module (E) also comprises two choppers (15, 15') for pulsed current generation, the current being needed by an optimizer of the electric power provided by the photovoltaic battery (4), consisting of a magneto-electric module (D) fixed inside the support cylinder (17) of the electric lamp ( C) and meant to optimize the electric charging of the batteries (13, 13'), which comprises two cylindrical magnets (7, 7'), at the most, coupled with the co-linear polarizations of at least one ferromagnetic bar (6), on which there is a small solenoid winding (8, 8') supplied with pulsed current from the photovoltaic battery (4), through the chopper (15), for periodically diminishing the magnetic flux generated by the cylindrical magnets (7, 7'), which also has two pairs of collecting windings (9, 9' and 10, 10') and at least one medial collecting winding (11), as well as a magnetic transformer (B) located within the support (1) and consisting of some modules (M, M') for optimizing the supply of the electric lamp (C) from the batteries (13, 13'), which are located within a ferromagnetic support casing (5) wherethrough the magnetic field lines are closed.
