Abstract

The invention discloses a current adjustment type automatic on-off control system for a lighting lamp. The current adjustment type automatic on-off control system mainly comprises a diode rectifier U, a sound sensor MIC, a triode VT2, a triode VT3, a triode VT4, a switch S, a current adjustment circuit, a thyristor voltage stabilization switch circuit and a rectification amplification circuit, wherein the rectification amplification circuit is connected with the sound sensor MIC, a base of the triode VT2 and the a base of the triode VT4. Automatic on-off of the lighting lamp can be achieved according to environmental brightness change and sound information of the lighting lamp within an application range, a voltage signal output from the sound sensor MIC can be filtered and amplified, so that the voltage signal is more stable, the control effect of the current adjustment type automatic on-off control system is ensured, the problem that the lighting lamp is turned on by mistake can be effectively solved, and the power resource is greatly saved.

Description

technical field

[0001] The invention relates to a control circuit, in particular to a current-adjusting self-opening and closing control system for an illuminating lamp. Background technique

[0002] Current lighting lamps are usually controlled by a mechanical switch, and the power supply of the lighting lamp is controlled to be turned on and off by controlling the conduction and closing of the mechanical switch. However, during the use of the mechanical switch, it is very easy to be damaged due to the great mechanical wear and tear due to repeated operations. In order to solve the problem that the mechanical switch is easy to wear and damage during long-term use, people have adopted a voice control system that can collect sound information within the range of use of the lighting lamp to control the opening or closing of the lighting lamp. However, The existing sound control system has the problem of poor control effect, which leads to the lighting lamp being turned on by ...
