1. A method for identification of a light inductive charger, wherein the light inductive charger comprises a power base and a wireless charging receiver, in which the body of the power base has a light receiving hole for the light receiver to stand out, and the wireless charging receiver includes a light emitter comprising a light emitting component that can emit lights towards the light receiving hole;

  • the execution steps are as follows;

    (a) Put the light receiver of the emitting terminal in standby mode, switch on the power base and set to read light signals from the light receiver through the light receiving hole;

    (b) Check light sources, and transmit signals from the light receiver to the microprocessor for determination purpose via the voltage detection circuit;

    (c) Decide on brightness, if it is bright, proceed to step (d);

    otherwise, proceed to step (e);

    (d) No power supply without any cover or in bright places, if there is no electromagnetic wave energy is emitted, the light receiver will receive bright light rays and decide that no wireless charging receiver is placed on the power base, or there is no cover or the light receiver is in a bright place, so no power supply is needed, then proceed to step (a) again;

    (e) If there is any cover or the light receiver is in a dark place, when it suddenly darkens or the light receiver is always in a dark place, it is likely that the charging module is fully charged and the light emitting component will not respond;

    (f) Transmit electromagnetic wave energy to the receiving terminal in a short period of time, and if the charging module of the wireless charging receiver is not fully charged, it will feed light signals in the same period of time as the electromagnetic wave energy to the light receiver so as to enable the light emitting component to emit lights towards the light receiver in order to respond to the power base;

    this state shall be understood as requiring charging;

    (g) Decide on responses and the state of responses includes charging required and charging not required;

    if the light is dark, proceed to step (h);

    if the light is bright for a short period of time, proceed to step (i);

    (h) If there is no response, it means that no compatible receiving terminal of the wireless charging receiver is placed or that the charging module is fully charged without the need to supply power;

    (i) If there is any response, it indicates that the receiving terminal begins to transmit power, and the power base will begin to supply power to the wireless charging receiver upon confirmation of responses, and the light emitting component is continuously switched on in the charging process;

    (j) Recheck following a preset time period of charging, and the charging module will recheck at an interval of a time predetermined period;

    if the charging module is fully charged, it will not feed light signals to the light emitter and the charging process will be interrupted.
