Abstract
The invention provides an automated light-emitting apparatus, which can be disposed in an object, includes a light-emitting unit, a force-sensing module, and a power-generating module. The force-sensing module includes a first component and a second component engaged to the first component. When the object receives an external force, the force-sensing module changes the distance between a first portion of the first component and a second portion of the second component. Moreover, the power-generating module includes a coil coupled to a magnetic member, the magnetic member engaged to the first component, and a magnetic conductor engaged to the second component. Particularly, when the distance between the first portion and the second portion is changed, the coil generates an induced electromotive force for supporting the light-emitting unit with needed power.
