LED LIGHTING STRING

摘要

A lighting string includes LEDs at spaced-apart locations within the hollow interior of a length of clear plastic or vinyl tubing or other flexible tube of light-transmitting material. The LEDs are connected in an LED circuit. An input connector attached to a first end portion of the flexible tube connects the LED circuit to a separate source of electric power. An output connector may be included on a second end portion of the flexible tube for connecting the lighting string to a second similar lighting string. One lighting string embodiment includes multiple colors of LEDs within the flexible tube that are arranged in series-connected single-color groupings so that adjacent LEDs are of different color and LEDs of the same color are energized together. A second type lighting string includes shift registers and other circuit components within the flexible tube for sequentially energizing the individual LEDs according to a data signal and a clock signal to produce the appearance of movement along the tube. A controller connected to the input connector controls the LED circuit in order to achieve a desired visual effect, and a suitably programmed controller connected to eight parallel lighting strings of the second type can produce moving character displays.
