Abstract

A control circuit of a small night lamp comprises a power circuit having a battery, a solar cell, the battery being installed with a switch for controlling the turning on and off of the power; a sound sensing circuit having a sound pickup, two transistors; the sound pickup serving to sense sounds and then to conduct the transistors; a light circuit having a plurality of LED lights; and a main control circuit having a microprocessor which is connected to the sound sensing circuit and the LED lights; the main control circuit being actuated by the transistors of the sound sensing circuit; when the main control circuit is actuated, all the LED lights lighting up or the LED lights lighting up in turn.

Claims

1. A control circuit of a small night lamp comprising:

a power circuit having a battery, a solar cell, the battery being installed with a switch for controlling the turning on and off of the power;

a sound sensing circuit connected to the power circuit and having a sound pickup, two transistors;

the sound pickup serving to sense sounds and then to conduct the transistors;

a light circuit having a plurality of LED lights; and

a main control circuit connected between the sound sending circuit and the light circuit;

the main control circuit having a microprocessor which is connected to the sound sensing circuit and the LED lights;

the main control circuit being actuated by the transistors of the sound sensing circuit;

when the main control circuit is actuated, all the LED lights lighting up or the LED lights lighting up in turn.

2. The control circuit of a small night lamp as claimed in claim 1, wherein the power circuit includes a rectifier for rectifying AC current in DC current.
