This site provides information such as LED street light knowledge, new energy LED light design, outdoor street light Installation and maintenance, etc.
Do you know the outdoor street light knowledge ? We will introduce Basic knowledge of new energy LED street lights
After the wind power generator is installed, it is always in the severe test of nature. In addition to being attacked by wind, frost, rain, and snow, it may be attacked by lightning, hail and wind sand. The working environment of wind turbines is very bad, so the correct use and maintenance of wind turbines […]
The main difference between new energy LED street lamp and conventional street lamp is the different power supply. The power supply system of new energy LED street lamp is composed of solar cell module, wind turbine, battery and controller, which brings great difficulties to daily maintenance because of its standard, component quality and installation method. […]
The management and maintenance of urban lighting facilities are of great significance and considerable economic value and social value, and the more important in the world of energy shortage today. Urban lighting facilities can only maintain continuous and effective work under good maintenance conditions. If it is not well maintained, it will increase the aging […]
1.New Energy LED street light run management 1.1New energy LED street light operation management method Urban road lighting is an indispensable part of urban infrastructure. It provides lighting for people at night, which can effectively improve the safety of night driving, greatly reduce criminal criminal crimes, and promote urban prosperity and drive regional economic development. […]
In order to effectively control the power fluctuation caused by the change of wind speed, the control system adopts the method of adjusting the size of the unloaded load. When the difference between the measured power and the power consumption of the lead-acid battery circuit reaches a certain value, the threshold switch is closed, the […]
In the wind solar complementary LED street lamp, the controller mainly includes three parts: wind power control unit, photoelectric control unit and battery charge and discharge control unit. The control part controls the operation mode and disconnection of the wind turbine and solar cell array according to the sunshine intensity, wind power and load changes, […]
The size of the wind energy captured by the wind wheel of a wind turbine is proportional to the vertical windward area of the wind wheel. That is to say, for a certain wind wheel, when it is in the vertical wind direction (front windward), it captures more wind energy; and when it is not […]
(1) Mechanical speed limit protection.The purpose of setting the high wind speed limit protection is to effectively reduce the wind turbine when the wind turbine input energy is greater than the total energy that the system can consume and the energy stored by the system at a certain wind speed. The absorbed wind energy prevents […]
In many cases, no matter how the wind speed changes, the speed of the generator should be kept constant or not exceed a certain limit value. For this reason, a speed regulation or speed limit device is adopted. When the wind speed is too high, these devices are also used to limit the power output […]
Due to the instability and pulsation of the natural wind, the wind speed is high and sometimes small, and sometimes strong winds and storms occur. The speed of the wind turbine impeller changes with the change of the wind speed. If there is no speed regulation mechanism, The speed of the impeller of the wind […]
