Embodiment
[0012] Such as figure 1 Shown, the present invention mainly consists of diode rectifier U, photosensitive transistor VT1, transistor VT2, transistor VT3, transistor VT4, transistor VT5, one-way thyristor D3, resistance R1, resistance R2, resistance R3, resistance R4, resistance R5, resistance R6, Resistor R7, resistor R8, resistor R9, capacitor C1, capacitor C2, capacitor C3, street lamp EL, Zener diode D1 and Zener diode D2.
[0013] Wherein, the P pole of the Zener diode D2 is connected to the positive output terminal of the diode rectifier U, and the N pole is connected to the collector of the triode VT2 after passing through the Zener diode D1. The resistor R1 is connected in series between the collector of the transistor VT2 and the negative output terminal of the diode rectifier U. Therefore, the Zener diode D1, the Zener diode D2 and the resistor R1 jointly form a voltage stabilizer circuit. Both the Zener diode D1 and the Zener diode D2 are 2CW6 Zener diodes, and the...

The invention discloses an automatic control circuit for a street lamp. The automatic control circuit is characterized by mainly comprising a diode rectifier U, a phototriode VT1, a triode VT2, a triode VT3, a triode VT4, a triode VT5, a unidirectional thyristor D3 and the like. The automatic control circuit can automatically control the street lamp to be turned on when the environment brightness is not enough, and automatically control the street lamp to be turned off when the environment brightness is enough, the automatic degree is high and the street lamp does not need to be manually turned on or turned off, so that the condition that a lot of electric energy is wasted due to the fact that the street lamp is forgotten to be turned off when the light is enough during the day is avoided; and a lot of electric energy is saved.
Description
technical field [0001] The invention relates to a switch circuit, in particular to a street lamp automatic control circuit. 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 lamps, and it is easy to forget to turn off the street lamps during the day when the light is su...
