Night illumination device controlled by door lock

Abstract

The invention discloses a night illumination device controlled by a door lock. The night illumination device comprises an alternating-current power source, a touch electrode, a rectifier, a one-way silicon controlled rectifier, a voltage stabilizing diode, a first resistor, a second resistor, a third resistor, a fourth resistor, a fifth resistor, a sixth resistor, a seventh resistor, an eighth resistor, a first capacitor, a second capacitor, a first bulb, a second bulb, a first triode, a second triode, a third triode, a photoresistor, a potentiometer, and a music integrated chip of which the type is KD-9300. The night illumination device disclosed by the invention has the advantage of high sensitivity, and the touch electrode is connected with the door lock. When a person returns home and opens a door, a key touches the door lock and touches the touch electrode of the door lock, signals are transmitted to the base electrodes of the triodes so as to switch on the triodes, the music integrated chip is triggered to work so as to enable lamps inside and outside the door to simultaneously lighten, when the music integrated chip stops working, the lamps automatically go off , so that noise pollution can be avoided, and electric energy is saved, which is favorable for popularization and promotion.

Description

technical field [0001] The invention relates to an auxiliary lighting device at night, in particular to a night lighting device controlled by a door lock. Background technique [0002] Lighting is a measure of using various light sources to illuminate working and living places or individual objects. Its primary purpose is to create good visibility and a comfortable and pleasant environment. In this busy era, night lighting is also very important. When passing through the long When you arrive at home in a long dark corridor, when you are looking for a key to open the door, the help of a bright light will bring a lot of convenience. In response to the needs of the general public, many controllers that control the lights at night have gradually appeared. However, we used to use them at night The sound controller used to control the light is easy to cause noise pollution, reduce the service life of the bulb, cause waste of electric energy and inconvenient use, and is difficult t...
