ABSTRACT:
A light module for use with a plurality of light sources mounted to footwear, includes a power supply, an oscillator circuit, a power supply transmission circuit and a switch. The oscillation circuit supplies power to the light sources to sequentially cause illumination of the light sources. The switch has an open condition and a closed condition. A power transistor of the power supply transmission circuit has an input connected with the switch, and an output path connected between the power supply and the oscillation circuit for supplying power from the power supply to the oscillation circuit when the switch is closed and for terminating over time the supply of power from the power supply to the oscillation circuit when the switch is open. A bypass circuit includes diodes connected between the oscillation circuit and the switch to disable the oscillation circuit in order to continuously illuminate the light sources when the switch is closed. The bypass circuit is disabled when the switch is open. A first capacitive device of the power supply transmission circuit is connected between the input and the output path of the power transistor for storing a charge when the switch is closed and for discharging through the output path of the power transistor when the switch is opened to cause the oscillation circuit to sequentially supply power to the light sources and sequentially cause illumination of the light sources until the stored charge of the first capacitive device falls below a predetermined value.
