Abstract
The present invention provides a lighting system for use within a display sign, wherein the lighting system comprises a first module having a multi-layer circuit board and an arrangement of components electrically connected to the circuit board. The component arrangement includes a driver control chip that provides regulated voltage to the light emitting diodes, at least one surface mounted resistor, and a pair of light emitting diodes wherein each diode is mounted to a longitudinal end portion of the circuit board. Thus, the driver control chip is positioned between the light emitting diodes. The component arrangement further includes a high-frequency capacitor that filters undesired electrical noise and a rectifying diode that converts electrical potential from alternating current to direct current. A second module is electrically connected to the first module by a pair of flexible conductor wires. The second module includes a multi-layer circuit board and an arrangement of components electrically connected to the circuit board. The component arrangement of the second module is similar to that of the first module, wherein a light emitting diode is mounted to each longitudinal end…
