Abstract:
A light module for use with a plurality of light sources mounted to footwear, comprising:a power supply for supplying power;an oscillation circuit for supplying power to said light sources to sequentially cause illumination of said light sources;a switch having an open condition and a closed condition;a power supply transmission circuit connected between said power supply, said switch and said oscillation circuit for supplying power from said power supply to said oscillation circuit when said switch is closed and for ending the supply of power from said power supply to said oscillation circuit when said switch is open;a bypass circuit connected between said oscillation circuit and said switch to disable said oscillation circuit and continuously illuminate said light sources when said switch is closed, said bypass circuit being disabled when said switch is open; anda first capacitive device connected with said power supply transmission circuit for storing a charge when said switch is closed and for discharging through said power supply transmission circuit when said switch is opened to cause said oscillation circuit to sequentially supply power to said light sources and sequentially cause illumination of said light sources until the stored charge of said first capacitive device falls below a predetermined value.
