ABSTRACT:
An inductor induced light emitting bottle comprises a seat having a transformer therein; the transformer being connected to a power source for voltage reduction. A transparent bottle serves for receiving water. A first coil is made of copper wire. The first coil encloses a periphery of the transparent bottle. One end of the first coil passes through the though hole to be connected to a lower voltage output end of the transformer. A light emitting unit has a hollow transparent casing, a second coil, a LED lamp, a sealing cover. A diameter of the second coil is smaller than that of the first coil. The LED lamp is connected to two ends of the second coil. The light emitting unit is disposed in the transparent bottle so that the second coil of the light emitting unit is disposed in the first coil as a transformer when they are conducted.
