Abstract: A lighting assembly for illuminating a display case includes an LED that illuminates items placed in the display case. The lighting assembly can attach to a door, a door frame, or another structure of the display case.

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).

Abstract: A light source (10) comprises a light engine (16), a base (24), a power conversion circuit (30) and an enclosure (22). The light engine (16) comprises at least one LED (12) disposed on a platform (14). The platform (14) is adapted to directly mate with the base (24) which a standard incandescent bulb light base. Phosphor (44) receives the light generated by the at least one LED (12) and converts it to visible light. The enclosure (22) has a shape of a standard incandescent lamp.
