An illuminated sign for residence street address to be connected across the terminals of the button of a house bell. The sign comprises light emitting diodes (LED) which project light on a reflector and through a plate displaying opaque digits. The LED\s are constantly energized by a suitable direct current obtained by the rectification of the alternative current existing of the terminals of the house bell.

An illuminated street address sign for residence adapted to be connected across electrical terminals of a button actuating a doorbell having a voltage of 8 to 16 volts, said sign comprising: an elongated shallow casing, having a backwall and a roof portion forwardly extending from said backwall, said backwall being covered with a reflective surface, and said roof portion having a track tilted towards the reflective surface; a set of juxtaposed miniature, light emitting diodes (LED) mounted adjacent said roof portion and oriented for directing light on said reflective surface, said roof portion shielding said LED from frontal projection; a substantially flat translucent plate mounted in front of said roof portion and extending over said casing for closing the casing and enclosing the LED and said reflective surface, said translucent plate adapted to receive the light reflected from said reflective surface and to prevent glare, said plate adapted to receive substantially opaque digits on its surface for obstructing light received from the reflective surface; a circuit board mounted in said track, said circuit board comprising a printed circuit on which the LED\s are mounted in series with said terminals, at least one pair of diodes in said circuit for maintaining the current in said LED\s in a unidirectional direction, said casing having a removable lateral wall, the removal of said wall adapted to free the end of said track to allow the circuit board to slide in and out of said track, whereby the circuit is constantly energized to project light through the translucent plate and adapted to be obstructed by the opaque digits.
