Solar energy street lamp sunlight

详情

Solar energy street lamp sunlight during the day and recharge at night to use, without complex and expensive pipeline laying, the layout can be adjusted lighting, security, clean energy, without manual operation stable and reliable, maintenance-free savings in electricity bills.
1. System components
    System consists of components in solar cells (including bracket), LED lamp, the control box (with a controller, battery) and the poles of several parts; Beijing Tianzhu sun light efficiency of solar panels to **7Wp/m2, efficient, wind-resistant design of the system is very favorable; head part of the 1W*5W white LED and yellow LED 1W*5W integrated in printed circuit board arranged for a certain distance of the lattice as the light source plane. Control box with stainless steel as a material box, beautiful and durable; control box placed on maintenance-free lead-acid batteries and charge-discharge controller. The system selected valve-regulated lead-acid batteries, because of its minimal maintenance, it is also known as "maintenance-free battery" will help reduce the cost of system maintenance; charge and discharge controller is designed to take into account the full-featured (with photo control, time control, overcharge protection, over discharge and reverse polarity protection, etc.) and cost control, to achieve a very high price.
2. Work
    System works is simple, the use of photovoltaic solar cells made of the principle effects of daytime panels and to receive solar radiation into electrical energy output, through charge and discharge controller is stored in batteries at night when the illumination gradually reduced to about *0lux, Changsha photosynthetic solar open circuit voltage of about 4.5V battery plate, charge and discharge controller to detect movement of the voltage value, the battery on the caps discharge. 8.5 hours of battery discharge, the charge and discharge controller action, the end of battery discharge. Charge and discharge controller's main role is to protect the battery.
