Abstract
A light emitting diode illumination system comprises a printed circuit board with score lines allowing a user to break the board into segments. The segments are a plurality of printed circuit boards provided with electrical elements. The electrical elements include light emitting diodes, a plurality of resistors and a zener diode. The zener diode has an associated capacitor and a plurality of associated rectifying diodes. The rectifying diodes convert AC to DC. Two pairs of electrical contacts are provided. Either pair is capable of coupling the electrical elements to a source of electrical potential to illuminate the light emitting diodes with minimum current while generating minimum heat.
