Touch switch control circuit of fading type delay lamp

Abstract

The invention discloses a touch switch control circuit of a fading type delay lamp. The touch switch control circuit comprises 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 triode, a second triode, a field-effect transistor, a thyristor, a voltage stabilizing diode, a touch electrode plate, a bridge rectifier circuit and the lamp. According to the touch switch control circuit of the fading type delay lamp, when the lamp needs to be turned on, the circuit can be switched on just by touching the touch electrode plate, and then the lamp is turned on immediately; after a certain time delay, light of the lamp becomes dimming until the light goes out. A touch switch is only provided with two external lead wires and can be used for replacing a common lamp switch without changing original wire arrangement; the delay time can be changed by adjusting the resistance value of the sixth resistor. The touch switch control circuit is simple in structure and convenient to replace and has the popularization and use value.

Description

technical field [0001] The invention relates to a switch control circuit, in particular to a touch switch control circuit for a dimming delay lamp. Background technique [0002] With the development of society and the advancement of science and technology, the degree of development of a city can be measured to a certain extent by the penetration rate of lights in the city at night. At the same time, for the safety of people walking, street lights are installed in residential corridors, but Due to the aggravation of noise pollution in the city, the sound and light sensor lights installed in residential corridors are often awakened by the noise, resulting in a waste of power resources. At the same time, the sudden on and off of the lights will cause temporary blindness to the eyes. Contents of the invention [0003] The object of the present invention is to provide a touch switch control circuit for a dimming delay lamp in order to solve the above problems. [0004] The pre...
