Outdoor LED display screens, as the new favorite of future outdoor display advertising media, are widely used in finance, taxation, industry and commerce, postal and telecommunications, sports, advertising, factories and mining enterprises, transportation, education systems, stations, docks, airports, shopping malls, hospitals, hotels, banks, securities markets, construction markets, auction houses, industrial enterprise management, and other public places. So, how can outdoor LED displays achieve energy conservation?
1、 Reasonably adjusting the brightness of outdoor LED display screens
The LED display screen itself uses energy-saving materials, but the outdoor LED display screen has a large area and is still quite power consuming. Therefore, we need to adjust the brightness of the outdoor LED display screen reasonably according to changes in the environment.
2、 In structural design methods
Due to the influence of environmental factors such as air humidity and air salinity, outdoor LED display screens need to be designed with these factors in mind in order to save maintenance costs and achieve energy conservation and consumption reduction.
3、 Improving LED power supply
This plays an important role in the energy-saving of outdoor LED display screens. Currently, half bridge or full bridge high-efficiency switching power supplies are directly used for outdoor LED display screens. In addition, synchronous rectification has a significant energy-saving effect, reducing the power supply voltage as much as possible in a constant current driving state. By supplying power separately to the red, green, and blue chips, better energy-saving effects can be achieved.
