1. A night light for mains power sockets and wall sockets comprising:

  • a mains plug (1), said mains plug (1) having a first contact pin (10

    ) and a second contact pin (10), and the mains plug (1) with the contact pins (10, 10

    ) being constructed in such a manner that it fits into a standard mains power socket and a wall socket;

    a housing (2);

    at least one lighting unit (3, 6) for emitting a visible light permanently, said lighting unit (3, 6) having a first terminal (3a) and a second terminal (3b);

    a circuit (4), said circuit (4) being connected (9a) between the contact pins (10, 10

    ) of the mains plug (1) and the terminals (3a, 3b) of the lighting unit (3, 6), and the circuit (4) including at least one high-voltage capacitor (5) with small dimensions, said capacitor (5) having a first end (5a) and a second end (5b);

    wherein the circuit (4) is constructed in such a manner that the first contact pin (10

    ) of the mains plug (1) is connected to the first end (5a) of the capacitor (5) and the second end (5b) of the capacitor (5) is connected to the first terminal (3a) of the lighting unit (3, 6), wherein the second end (5b) of the capacitor (5) and the first terminal (3a) of the lighting unit (3, 6) have no direct connection to the mains plug (1), wherein the first contact pin (10

    ) of the mains plug (1) and the capacitor (5) and the lighting unit (3, 6) are connected in series, wherein a voltage at the lighting unit (3, 6) and a current through the lighting unit (3, 6) are reduced by the capacitor (5), so that extremely little electrical energy is burned off by the circuit (4), and wherein the lighting unit (3, 6) and/or the capacitor (5) are mounted on a board or printed circuit board (8).
