Solar energy, wind energy in each period, the seasonal and regional distribution is uneven, in order to ensure the stable operation of the lighting-weather inevitably require the entire system must be the best design to engineering to years of climate data and engineering lighting requirements, system energy production, storage, consumption to achieve the the dynamic best match and efficient operation. 1, system design: Constant really has a strong team of experts, many years of practical experience and success stories will provide strong backing of the successful implementation of the project. 2 Technology: A MPPT MPPT and battery intelligent charging management technology makes the system power and charging efficiency of 10% -20%. B, high frequency switching and automatic control pulse width modulation technology and intelligent discharge management technology, alternative the general constant current source drives plus a simple electronic switch control mode, comprehensive energy efficiency up to 30% -60%. C, the use of LED lamp beads using well-known companies in the world's top chip and using the oversized stent flip technology, one-time molding the approximate rectangular beam optical lens realize the effect of high luminous efficiency, low light failure, bad light control in every 20,000 hours less than 3%, the highest luminous efficiency reach 130lm / W. D, using a unique formula and gas-liquid separation technology, to extend the battery life of 2-3 times. Together technology and the best system is designed to ensure that the high cost of the lighting system, maintenance-free, free testing, free management; resist ENGINEERING longest rainy days, 365 days all night working properly, breaking comprehensive pure new energy LED lighting system promote the application of technical bottlenecks. Our solar street light has the following characteristics: 1. Photovoltaic modules Featured efficient Class A single (multi) chip and high transmittance optical special glass packaging components, electricity production stable enough power; 2 LED lamp beads used by the Division CREE company's top chip the oversized bracket and flip-chip technology, forming the approximate rectangular beam optical lens, and realize the effect of high light efficiency, low light failure, bad light control in every 20,000 hours to less than 3%, the highest light efficiency reach 125lm / W. 50WLED lamps equivalent to 250W high pressure sodium lamp illumination, 30W equivalent to 150W high pressure sodium lamp illumination; battery nanotechnology applications, batteries breathable water can be battery directly buried in the ground to get the best work environment, conducive to maintaining constant working temperature to extend the battery life of more than 1.5 times. The controller has the following features: A. battery overcharge and over discharge protection, over ten function; B, MPPT MPPT and battery intelligent charging management technology allows the system power generation and charging efficiency improvements of 10-20%. C, switch and automatic control of high-frequency pulse width modulation technology, and intelligent discharge management technology, alternative the general constant current source drives plus a simple electronic switch control mode, integrated energy-saving rate of 30-60% D. built-in the SPC power adjustment module can be achieved after midnight gradual power adjustment function, more than 20% of the energy-saving. E. in debugging over-charge and over-discharge protection, solar panel, controller, battery, light source to implement a one-to-one precise debugging, 1.5 times longer battery life and extend LED life of more than 1.5 times. The installation of solar street lights is very user-friendly, a lamp stand good light pole, waterproof connectors can be connected to 5-7, wires and connectors dedicated for solar and life to meet the demand for 30 years of use.
