20100289415 | Energy efficient decorative lighting - Energy efficient system for lighting is provided that allows variation of length, density of illumination and positioning. The inventive system is particularly suitable for decorative lighting and seasonal display. The lighting system comprises at least one light string having a plurality of light emitting diodes (LEDS) interconnected to a parallel set of power wires maintaining output voltage within a prescribed range. A direct current (DC) transformer is connected to the parallel set of power wires to convert alternating current (AC) input to DC output to control power to the lighting system at relatively low voltage level and less than about fifteen watts. Multiple LED light strings may be connected to the parallel set of power wires to provide decorative lighting displays of desired length, configuration and density of illumination. Accordingly, the unique system provides decorative lighting that is energy efficient and suitable for low cost manufacture compared with conventional incandescent light strings. | 11-18-2010 |
