It's not very difficult to quote the price of solar street lamp automatically. Working principle of solar street lamp quotation: the photovoltaic panel of solar street lamp quotation collects light energy and converts it into electric energy, which is stored by storage battery for LED lighting at night. < br / > in general, the street lamp control devices provided by solar lamp manufacturers have timing, light control, and even rain control functions, so it is very convenient to use. If your solar street lamp only has battery and LED light source and light source power supply circuit, but no circuit control. We know that if we want to control the lighting of the 220 V lighting circuit, we only need a 220 V timer to automatically switch on and off, while the solar street lamp is powered by batteries. How can we control it? < br / > < br / > < br / > < br / > < br / > < br / > < br / > at present, the solar street lamp control system can be divided into two categories: < br / > one type: to use the ordinary solar street lamp controller, you need to use the remote controller to set the opening and closing time of the solar street lamp in advance and its own brightness. < br / > class II: single light controller of Internet of things, with Internet of things control function, can use mobile phone small program, and computer client, one key to send instructions, with remote control, detection, fault alarm and other advantages. < br / > the method to transform the ordinary acousto-optic street lamp switch into the household solar street lamp switch is as follows: < br / > < br / > < br / > < br / > < br / > < br / > < br / > (1) remove the part of the circuit that supplies power to the control circuit through the step-down rectification of the transformer or the resistance and capacitance, and replace it with the solar power supply (if the voltage is a little high, the resistor can be used to reduce the voltage) Electricity. < br / > (2) if the position of the automatic control switch is too high from the ground, the intensity of the sound reaching the control switch may not be enough to trigger the voice control function, that is, the street lamp may not be on at night. At this time, you can short-circuit the microphone (directly use a wire jumper), and do not use the voice control function. Of course, if the control switch is not high from the ground, I hope there is When people pass by, the light will be on, which can still keep the original voice control part of the control circuit. < br / > (3) the relay does not need to be changed. < br / > (4) change the 220 V input of the relay secondary to the solar power input.
