ABSTRACT:
Footwear includes a heel; an upper; a light source mounted to at least one of the heel and upper; and a light module positioned within the heel, the light module including a power supply for supplying power; a capacitor for storing power from the power supply and for discharging the stored power, the capacitor being connected with the light source to activate the light source; a switch for alternately opening and closing a connection between the power supply and the capacitor upon movement of the footwear, such that when the switch closes the connection, the capacitor charges to a full capacity thereof as determined by the power supply, and the light source is activated to emit light at a first intensity in accordance with the full capacity of the charge on the capacitor, and when the switch opens the connection, the capacitor discharges from the full capacity thereof, and the light source is activated to emit light at an intensity less than the first intensity and which decreases over time, in accordance with the discharge, to produce a fading effect; and a photosensor for sensing ambient light and for preventing activation of the light source when the photosensor senses ambient light of an intensity greater than a predetermined intensity, regardless of whether the switch is open or closed.
