Solar street lights can achieve lighting effects without connecting to the grid

　　As a kind of energy-saving lighting equipment, solar street lights have gradually entered people's lives. Recently, Changhui realized the independent switch and adjustment control of solar street lights. Moreover, the LED light source is a new type of lighting equipment, which is different from traditional lighting equipment. It not only saves electricity, but also has high-speed switching action, so the non-stop switching action will not affect the normal lighting use.

　　The luminous efficiency of the solar panel can reach 127Wp/m2, and the efficiency is very high, which is very beneficial to the wind resistance design of the solar street lamp lighting system. The lamp holder part is integrated with 1W white LED and 1W yellow LED on the circuit board. The spaced dot matrix is u200bu200bused as the plane light source.

　　 This lighting system uses a valve-regulated sealed lead-acid battery, which is also called a maintenance-free battery because it is rarely maintained, which is conducive to reducing system maintenance costs. At the same time, the charge and discharge controller is designed to take into account the functions. Light control, time control, over-charge protection, over-discharge protection and reverse connection protection, etc. and cost control, to achieve a very high cost performance.

　　Solar street light is a solar cell module made using the principle of photovoltaic effect. During the day, solar panels receive solar radiant energy and convert it into electrical energy output, which is then stored in the battery through the charge and discharge controller, and the charge and discharge controller detects After this voltage value is activated, the battery discharges the lamp cap. After the battery is discharged for a certain period of time, the charge-discharge controller will act and the battery discharge ends. The main function of the charge and discharge controller is to protect the battery, so that the solar street light can be illuminated without connecting to the grid.
