Abstract

An electric sign device can include a backboard; first and second metal strips attached to the backboard; a plurality of LED assemblies, each LED assembly comprising: a board; first and second metal contacts attached to a first side of the board; first and second magnets attached to the first and second metal contacts, respectively; the first and second metal contacts contacting the first and second metal strips, respectively; a plurality of LEDs disposed on a second side of the board, the plurality of LEDs being electrically connected to the first and second metal contacts; and a carrier having one or more channels or apertures that receive the plurality of LEDs, the carrier being attached to the board; wherein the first and second magnets are magnetically attached to the first and second metal strips, respectively, so that the each LED assembly is magnetically attached to the backboard.

An electric sign device, comprising:

a first board;
a first metal strip attached to the first board, the first metal strip having at least a first length and extending along the first board;
a second metal strip attached to the first board, the second metal strip having at least the first length and extending along the first board, the second metal strip being separated from the first metal strip;
a first light emitting diode (LED) assembly, comprising:
a second board having a first width that is smaller than the first length;
a first magnet;
a first metal contact attached to a first side of the second board, the first metal contact being constructed and arranged to receive the first magnet, the first metal contact being constructed and arranged to contact the first metal strip;
a second magnet;
a second metal contact attached to the first side of the second board, the second metal contact being separated from the first metal contact, the second metal contact being constructed and arranged to receive the second magnet, the second metal contact being constructed and arranged to contact the second metal strip;
a first plurality of LEDs disposed on a second side of the second board, the first plurality of LEDs being electrically connected to the first metal contact and the second metal contact;
and
a first carrier having one or more first channels or apertures that are constructed and arranged to at least partially receive the first plurality of LEDs, the first carrier being attached to the second board;
wherein the first magnet is constructed and arranged to be magnetically attached to the first metal strip and the second magnet is constructed and arranged to be magnetically attached to the second metal strip so that the first LED assembly is magnetically attached to the first board;
a second LED assembly, comprising:
a third board having a second width that is smaller than the first length;
a third magnet;
a third metal contact attached to a first side of the third board, the third metal contact being constructed and arranged to receive the third magnet, the third metal contact being constructed and arranged to contact the first metal strip;
a fourth magnet;
a fourth metal contact attached to the first side of the third board, the fourth metal contact being separated from the third metal contact, the fourth metal contact being constructed and arranged to receive the fourth magnet, the fourth metal contact being constructed and arranged to contact the second metal strip;
a second plurality of LEDs disposed on a second side of the third board, the second plurality of LEDs being electrically connected to the third metal contact and the fourth metal contact;
and
a second carrier having one or more second channels or apertures that are constructed and arranged to at least partially receive the second plurality of LEDs, the second carrier being attached to the third board;
wherein the third magnet is constructed and arranged to be magnetically attached to the first metal strip and the fourth magnet is constructed and arranged to be magnetically attached to the second metal strip so that the second LED assembly is magnetically attached to the first board.
