Abstract

A magnetic induction charged candle includes candle, holder and charger. Said candle and holder are equipped with printed circuit board (PCB), integrated circuit (IC), light emitting diode (LED), battery, switch, and terminal respectively. In that, the terminals can be coupled with each other. Thereby, the candle can be combined and mounted to the holder. At the bottom end of the holder has an electromagnetic coil corresponding to an electromagnetic coil inside the charger. When the holder is place into the charger, an electromotive force is produced between the two electromagnetic coils to induce currents. Thereby, the candle and the holder can be charged at the same time. Even the candle and the holder are not equipped with power line, they can be charged with full capacity of electricity. Moreover, the chargers can be in connection with one another in-line to expand the charging capacity.

Claims

1. A magnetic induction charged candle comprising:

a candle having a housing includes a diffuser resembling a fume on the top end, and a luminary installed inside the housing;

said luminary includes a vertical printed circuit board (PCB) with a light emitting diode (LED), a battery, a linking terminal installed to the PCB, said LED raised above the top end of the PCB, said terminal dangled from the PCB to expose the terminal below the housing;

a holder being a base pervious to light having an upper chamber and a lower chamber, a luminary mounted inside the lower chamber, and a lid for covering the opening of the bottom end of the lower chamber, said luminary includes a horizontal PCB with an LED, a battery, a terminal T2, and an electromagnetic coil installed to the surface of the PCB, said terminal is extended from the PCB into the upper chamber to connect to the terminal of the candle, an electromagnetic coil disposed below the PCB;

a charger having a housing, a horizontal PCB mounted inside the housing, and a lid for covering the opening at the bottom end of the housing;

said PCB equipped with an electromagnetic coil to correspond to the electromagnetic coil inside the holder, a socket for receiving a sheath type plug, said socket is exposed outside the housing.

2. A magnetic induction charged candle according to claim 1 wherein the luminary of the candle includes integrated circuit (IC) to process the modes of emitting light of the LED.

3. A magnetic induction charged candle according to claim 1 wherein the luminary of the holder includes IC to process the modes of emitting light of the LED.

4. A magnetic induction charged candle according to claim 1 wherein the PCB of the candle is equipped with a switch exposed outside the candle to actuate the candle.

5. A magnetic induction charged candle according to claim 1 wherein the PCB of the holder is equipped with a switch exposed outside the holder to actuate the holder.

6. A magnetic induction charged candle according to claim 1 wherein the charger equipped with a sheath type plug can plug into a socket of other charger.

7. A magnetic induction charged candle according to claim 1 wherein the sheath type plug has a button exposed outside the housing to determine the sheath type plug whether pop out or not.
