ABSTRACT:
A light-emitting safety device is embedded in the transparent heel of shoe and is composed of a base, a circuit board housed in a receiving space of the base, and a deformable cap engaged with the base. The circuit board is composed of a light-emitting body, a control integrated circuit, a battery, and two connection points. The cap is provided with a conductive member capable of connecting the two connection points so as to trigger the control integrated circuit to make the power supply available to the light-emitting body when the cap is deformed by the pressure of a foot wearing the shoe. As soon as the cap is relieved of the pressure of the foot, the cap is capable of recovering its original form such that the conductive member disengages the two connection points, thereby resulting in the interruption of the power supply to the light-emitting body.
