ABSTRACT:
An illuminated sign (88) includes a flexible electrical power cord (100) including first and second parallel conductors (112, 114) surroundingly contained within an insulating sheath defining a constant separation distance between the parallel conductors (112, 114). A plurality of light emitting diode (LED) devices (102) are affixed to the cord (100). Each LED device (102) includes an LED (104) having a positive lead (130p) electrically communicating with the first parallel conductor (112) and a negative lead (130p) electrically communicating with the second parallel conductor (114). A stencil (92) defines a selected shape, and the electrical cord (100) is arranged on the stencil (92). Power conditioning electronics (210, 220) disposed away from the stencil (92) electrically communicate with the first and second parallel conductors (112, 114) of the electrical power cord (100). The power conditioning electronics (210, 220) power the LED devices (102) via the parallel conductors (112, 114).
