Description of the embodiments
The utility model is described in detail below with reference to the accompanying drawings.
Examples: see fig. 1-3; an inductive lighting circuit for a smart switch, comprising: an illumination electronic switching unit and a sensor;

As shown in fig. 1, in the prior art, there is no delay charge-discharge circuit, the output end of the sensor is directly connected with the control end of the lighting electronic switch unit, and the on-off of the lighting electronic switch unit is controlled by the sensor, so as to control the lighting. The technical scheme is that a delay charge-discharge circuit is arranged between the output end of the sensor and the lighting electronic switch unit, and the working process is that: when sensing that there is the human body, the sensor output sends the signal to the control end of charging electronic switch unit, and charging electronic switch unit is in the on-state, and the power charges to the electric circuit that stores up, and the charging time can be set up according to the requirement, and when the electric energy of electric circuit reserves to the default, the high level output sends the signal to lighting switch electronic unit, and lighting switch electronic unit switches on, lamps and lanterns illumination. If the human body leaves during the electricity storage period, the high-level output end does not send out a signal. Thereby preventing false triggering.
During the lighting process, the power storage circuit continues to store power. When the human body is sensed to leave, the output end of the sensor stops sending out signals, the charging electronic switch unit is cut off, and the power supply stops supplying power to the power storage circuit; because the electric energy of the electric storage circuit is higher than the preset value at this moment, the high-level output end can continuously send out signals until the electric energy consumption of the electric storage circuit is lower than the preset value, so that the power failure is avoided to stop lighting once a human body leaves.
Further, the power storage circuit comprises an energy storage branch circuit, the energy storage branch circuit comprises a capacitor C1 and a capacitor C2 which are connected in parallel, the output end of the charging electronic switching unit is grounded through the energy storage branch circuit, and the capacitor C1 is connected with a resistor R5 in parallel, a resistor R6 and a resistor R7 which are connected in series; the output end of the resistor R6 is connected with a triode Q3 and is connected with the base electrode of the triode Q3, the emitter electrode of the triode Q3 is grounded, the collector electrode of the triode Q3 is connected with a MOS tube Q4 through a resistor R8 and is connected with the grid electrode of the MOS tube Q4, the source electrode of the MOS tube Q4 is connected with a power supply through a resistor R4, and a resistor R10 is connected between the source electrode and the drain electrode of the MOS tube Q4; the drain electrode of the MOS tube Q4 is grounded through a resistor R9 and is connected with the high-level output end.
When the storage circuit works, when the charging electronic switch unit is turned on, the power supply supplies power to the energy storage branch to store energy, 1, when the energy storage of the capacitor C1 and the capacitor C2 has no preset value, the potential between the resistor R6 and the resistor R7 which are connected in series does not have the bias voltage threshold value of the base electrode of the triode Q3, such as 0.7V; the triode Q3 is cut off; no potential difference or very small potential difference exists between the source electrode and the drain electrode of the MOS tube, and the MOS tube is also cut off; if the charging electronic switch unit is turned off, the energy storage branch circuit, the resistor R5, the resistor R6 and the resistor R7 connected in series form a loop, and the energy storage branch circuit discharges.

3. In the working process, the capacitor C1 and the capacitor C2 are continuously charged, when the charging electronic switch unit is turned off, the capacitor C1 and the capacitor C2 are externally discharged, and after the time t2, the energy storage value of the capacitor C1 and the capacitor C2 is lower than a preset value, and the triode Q3 is kept on between the capacitor C1 and the capacitor C2, so that the power failure is prolonged.
