ABSTRACT:
A fixing structure for the light sensitive lightening circuit of 2-stage microswitch type on a lightening shoe, wherein the shoe heel is excavated to form a receiving recess having fixing holes on the top surface and a shallow concave groove on the bottom surface thereof; a transparent fixing seat has at the top thereof lugs corresponding to the fixing holes, further at the bottom thereof a receiving groove corresponding to the shallow concave groove for receiving a lightening circuit board; the fixing seat is insertable into the receiving recess of the heel, and is formed a part of the heel by joining the lugs with the fixing holes. The circuit can be activated through the darkening of circuference, and the LEDs in the circuit can shine intermittently following another activation by the trampling action on the shoe created by walking or dancing.
