ABSTRACT:
The invention involves an inexpensive, rugged, flexible, composite plastic backlight panel that provides an even heat distribution across the entire surface of the backlight panel for a convertible top of a vehicle. Two wires are connected to the car battery. A series of conductive members are each in electrical engagement with each of the wires, forming a closed loop electric circuit. The conductive members are printed onto one of the laminates, forming an interlayer thereon. An inner transparent plastic laminate, and an outer transparent plastic laminate are sandwiched around one end of each of the wires, and the interlayer. The laminates including the wires and members are bonded together and the resulting panel is secured to the convertible top thereby forming the backlight panel. When the circuit is energized, the electrical energy is converted into thermal energy that is transmitted to the outer laminate.
