Patent ID: 7025473

Claim:
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 ( 3 a ) and a second terminal ( 3 b ); a circuit ( 4 ), said circuit ( 4 ) being connected ( 9 a ) between the contact pins ( 10 , 10 ′) of the mains plug ( 1 ) and the terminals ( 3 a , 3 b ) 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 ( 5 a ) and a second end ( 5 b ); 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 ( 5 a ) of the capacitor ( 5 ) and the second end ( 5 b ) of the capacitor ( 5 ) is connected to the first terminal ( 3 a ) of the lighting unit ( 3 , 6 ), wherein the second end ( 5 b ) of the capacitor ( 5 ) and the first terminal ( 3 a ) 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 ).
