Abstract
Flexible LED light arrays particularly suitable for use in clothing and other articles are disclosed. The light arrays are disposed on flexible printed circuit boards (PCBs). The flexible PCBs include substantially sinusoidal metal contact traces, along which the LEDs are attached at an angle preselected to minimize stresses in the expected directions of bending. The flexible PCBs may have control electronics provided on separate, attachable control boards, which may be either flexible or rigid. The flexible LED light arrays may also be arranged in master-slave configurations with a number of arrays, in which one master control array or board is attached to a number of slave arrays and handles external communication for the slave arrays.
