Street lamp lighting circuit design features and advantages

At present, the light pole lighting accounts for 25% ~ 30% of total energy consumption of lighting, road lighting energy saving has a great potential and space. At present, the road lighting is the most widely used in high pressure nano light. The light source to save poor color rendering, long start-up time, high power consumption and high calorific value of the



at present, the light pole lighting accounts for 25% ~ 30% of total energy consumption of lighting, road lighting energy saving has a great potential and space. At present, the road lighting is the most widely used in high pressure nano light. The light source to save poor color rendering, long start-up time, high power consumption and high calorific value faults. Using integrated operational amplifier ( Integrated operational amplifier ( 集成运算放大器) Referred to as 'integrated op-amp, multistage direct coupling amplifier circuit is made of high gain analog integrated circuits. 】 Voltage comparator consisting of 【 Voltage comparator is to identify and compare circuit of input signal, is the basic unit of the sine wave generating circuit circuit. 】 As a light pole control circuit. The circuit is composed of a hardware control system, simple and reliable, easy maintenance, low cost, low power consumption. This is a matching circuit with good sex. The key is according to the storage battery charging and discharging characteristics of the circuit to design a good homodyne voltage source. At the same time, the choice of equipment to be reliable. In addition, the charge and discharge status indication circuit composed of leds become a practical control circuit, have prevent the battery discharge and charge function. Street lamp light pole battery charging protection circuit is made up of zener diode 【 Zener diode, English name Zener diode, also called Zener diode. 】 , transistors and resistors, simple circuit. When the solar panels 【 Solar panels, 太阳能板) Is by absorbing sunlight, the solar radiation through the photoelectric effect or photochemical effect directly or indirectly converted into electrical energy device, the main material of most of the solar panel as the 'silicon', but because of the production cost is larger, so it widely used, we still have some limitations. 】 To recharge the battery, solar panel and battery connection between a diode, to prevent the reverse charge battery for solar panels. A major part of the battery over discharge protection circuit is hysteresis comparator and relay. Using the hysteresis comparator to judge whether batteries for discharge, relay as a selector switch, choose to battery power supply or standby power supply.
