Patent ID: 8419253

Claim:
A lighting display system having an anti-theft feature, the system comprising: a mounting structure comprising: at least one mounting plate having a front side and a back side; a first conductor line carried by the at least one mounting plate; a second conductor line carried by the at least one mounting plate and spaced apart and electrically insulated from and extending parallel to the first conductor line; a plurality of first holes traversing the at least one mounting plate adjacent to the first conductor line, wherein the holes are arranged such that non-uniform separation exists between the holes; a plurality of second holes traversing the at least one mounting plate adjacent to the second conductor line, wherein the holes are arranged such that non-uniform separation exits between the holes; and a power supply terminal electrically connected to the first and second conductor lines and which is connectable to a power supply; and a plurality of luminescent bodies, wherein each of the plurality of luminescent bodies comprises: a first contact plug exposed at a back side of the luminescent body and electrically connected to the first conductor line; a second contact plug exposed at a back side of the luminescent body and electrically connected to the second conductor line, wherein a line extending between centers of the first and second contact plugs is oriented at an angle α of more than 105° or less than 85° relative to a direction of extension of the first conductor line; and a plurality of light sources electrically connected to the first and second conductor lines via the first and second plugs, such that the light sources are energized when the first and second conductor lines are connected to the power supply; and wherein a line extending between centers of any of the first or second holes is never perpendicular to a direction of extension of the first conductor line.
