solar is the most direct the most common and most clean energy, solar energy as a huge amount of renewable energy. As the traditional energy increasingly scarce, the application of solar energy will be more and more widely, especially in solar power field within the short several years has developed into a mature sunrise industry. At present, the road lighting accounts for 25% ~ 30% of the entire lighting electricity consumption, so the road lighting energy saving has a great potential and space. The road lighting is the most used high pressure sodium lamp' High pressure sodium lamp is a kind of high intensity discharge lamp, belongs to the third DaiDian light source, its luminous tube use translucent alumina tube, lamp shell adopts hard glass. 】 Poor, this kind of light source color rendering, long start-up time, the high power consumption and calorific value, need to develop new ways of more energy-efficient lighting source. High power LED high photosynthetic efficiency is at home and abroad in recent years, rapid development of new light source, it has high photosynthetic efficiency, ≥90 lmPW( 1 w
领导) ) , long life, 30000~50000h) , resistant to vibration is not easy to damage, the instantaneous start, no pollution, etc. White LED
is an ideal light source to general lighting and road lighting. Solar street light has many advantages: safe, reliable, convenient maintenance; Don't need to conventional energy, do not pollute the environment; Can put everywhere according to need, don't have to connect the public power grid. Therefore, development of
LED street lamp has the important significance of energy saving. In this paper, on the basis of the original solar street light system is proposed and developed a new type of intelligent LED solar street light system. 1 solar street lamp system of street lamp system consists of the following several parts: 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. 】 , booster circuit module, controller module, Zigbee 【 ZigBee is based on IEEE802. 15. Four criteria of low-power LAN protocols. 】 Communication components, battery' Battery is a kind of independent and reliable power supply, it is not affected by the ac power, when any accidents which happen in power plant or transformer substation, even in the whole factory, total station under the condition of the ac power is power outage, still can guarantee the dc electrical equipment in the system is reliable and continuous, smooth and voltage; At the same time also can be used as a factory, total station, emergency lighting power supply, uninterrupted power supply is the last barrier. 】 , LED light source. The basic operation principle of the system: the solar controller Called the solar controller solar charge controller, is used for solar power generation system, the control of multiple solar cell phalanx of battery and battery for solar power inverter load automatic control equipment. 】 Under the control of solar panels during the day after two road booster circuit ( The 12 v to 42 v) To the battery charge, battery to provide power to the LED at night
light load. In the control module, and realized the booster circuit, battery voltage, temperature,
LED headlamp unit temperature real-time control of voltage, panels, and through the analog switch data feedback to the PIC of street lamp intelligent control system. And Zigbee module for street lamp system network provides a reliable technical guarantee.
