Abstract

The invention discloses an automatic control circuit for a high-stability streetlamp and with an overcurrent protection function. The automatic control circuit is characterized by being mainly composed of a diode rectifier U, a fuse FU, an audion VT1, a phototriode VT2, an audion VT3, an audion VT4 and the like. The automatic control circuit can automatically control the streetlamp to be turned on when ambient brightness is not high enough, and can automatically control the streetlamp to be turned off when ambient brightness is high enough, so that the degree of automation is high, the street lamp does not need to be manually turned on or off, the situation that a person forgets to turn off a street lamp under sufficient light during the daytime, and consequently a large amount of electric energy is wasted can be avoided, and electric energy is saved to a great extent. The automatic control circuit can well filter out alternating components in direct-current voltage, so that the streetlamp works more stably, and the lighting effect of the streetlamp is improved.

Description

technical field [0001] The invention relates to a switch circuit, in particular to a high-stability street lamp automatic control circuit with overcurrent protection. Background technique [0002] Energy shortage is a serious problem in the development of human society, but people often waste a lot of electricity inadvertently in their lives. For example, most of the current street lights are manually turned on and off. This control method is cumbersome, and it is easy to forget to turn off the street lights during the day when the light is sufficient, resulting in a lot of waste of electric energy. Therefore, it is an urgent task at present to provide a control circuit that can automatically control the on and off of street lamps according to the ambient brightness. Contents of the invention [0003] The purpose of the present invention is to overcome the cumbersome way of manually controlling the on and off of street lights, and it is easy to forget to turn off the stre...
