Photovoltaic solar street lamps system configuration technology

A, solar street lamps light source adopts special solar power LED light source, according to the customer need to choose pury chips, more than 130 lm/w, more than hundreds of hours of life, light failure is less than 20% after 50000 hours. Second, solar street lamps controller using optical add

a, solar street lamps light source for solar special high power led light source. The prius chips are chosen according to the customer's demand. Light source of the life of more than 100000 hours, 50000 hours after the light attenuation is less than 20%. Second, solar street lamps controller controlled by intelligent machine, equipped with optical control and time control. It requires low power consumption. With over charge, over discharge protection, battery open circuit protection, load over-voltage protection, short circuit protection, reverse connection protection and time delay, floating, temperature compensation, electric time control, moisture protection, automatic switching and time adjustment, etc. In order to ensure the reliable operation of the system. Three battery USES the valve control specially used for solar street lamps, solar street lamp sealing colloid and maintenance-free battery, the service life of more than five years, using the temperature range for - 25 ℃ ~ + 50 ℃, requires depth charge and discharge function. Four, solar road lighting panels 1. Solar street light battery is solar street lamp system is the most important energy collection system, taking for the solar street light system to provide the important task of traffic light energy. To this end, the company adopt international famous brand yingli solar single ( More) Crystalline silicon solar panels, the panels of minus reflection film for plasma enhanced chemical vapor deposition silicon nitride film. High conversion efficiency, long service life, after-sales service effectively. 2. Solar street lamps solar lamp panel module framework: module framework by anodic oxidation of high quality aluminum alloy frame, the surface of alumina film thickness is 25 microns. It requires strong and durable, and can withstand the winds in not less than 35 m/SEC. 3 solar panels imported low iron tempered glass, The iron content is less than 0. 02%) Toughened glass, most of the spectral band of light transmittance is greater than 92%. Although the solar cell components of packaging materials is a kind of auxiliary material, but it also to give full play to the function of the solar cell has a great influence. Therefore, it is imported from abroad with anti-aging EXA ( Ethylene - Vinyl acetate polymers). And the high quality with good weatherability TPT ( Composite fluorine plastic film) Laminated together.
