3 h, 5 h and 8 h are set to light for three hours, five hours and eight hours.
The hollow round sun is full brightness, and the semi-solid round sun is half brightness.
On is on, off is off.
Automatically turn on from dim light and automatically set to turn off at dawn.
When the solar panel senses darkness, lighting begins.
Extended data
During the day, even on cloudy days, this kind of solar generator (solar panel) can collect and store solar energy. As a new type of safe and environmentally friendly electric lamp, solar lamp has attracted more and more attention.
Solar lamp is composed of solar cell module, some LED lamps, control box (with charger, controller and storage battery in the control box) and lamp post. The light efficiency of the solar panel reaches 127Wp/m2, with high efficiency, which is very beneficial to the wind-resistant design of the system.
In the lamp holder part, 1W white LED and 1W yellow LED are integrated on the printed circuit board and arranged in a dot matrix at a certain distance as a plane light source. The control box is made of stainless steel, which is beautiful and durable; Maintenance-free lead-acid batteries are placed in the control box, and a special charging controller for solar street lamps is successfully developed by using patented slow pulse fast charging and discharging technology.
The system adopts valve-controlled sealed lead-acid battery, which is also called "maintenance-free battery" because of its less maintenance, which is beneficial to reduce the maintenance cost of the system. The design of the charge and discharge controller considers the complete functions (including light control, time control, overcharge protection, overdischarge protection and reverse connection protection, etc.). ) and cost control to achieve high cost performance.
