more and more outdoor advertising pictures and video advertisements and outdoor dynamic information need to be played. These are not achieved by traditional inkjet billboards. At present, only outdoor LED electronic screens can better achieve these functions.
the annual power consumption of outdoor LED electronic screens in China is 16.7 billion kilowatt-hours, which is equivalent to the power generation of the Three Gorges Dam in about 60 days, equivalent to about 8.5 million tons of raw coal consumption, and nearly 17 million tons of carbon dioxide emissions.
This fully reflects the value created by outdoor LED electronic screens for the society, and reflects the trend of outdoor LED electronic screen use.
Therefore, although the outdoor LED electronic screen consumes a lot of power, we can’t use it, we can only find ways to save power.
So, how can outdoor giant LED electronic screens save electricity? gave the following suggestions:
1. Using high-efficiency LED, the light-emitting chip does not cut corners;
2. Using high-efficiency switching power supply, greatly improving the power conversion efficiency;
3. Carry out excellent heat dissipation design of the screen to reduce the power consumption of the fan;
4. Design a scientific overall circuit plan to reduce the power consumption of internal circuits;
5. Automatically adjust the brightness of the outdoor LED electronic screen according to changes in the external environment.
Through the above measures, the power consumption of outdoor LED electronic screens can be greatly reduced. At the same time, the improvement of efficiency and the reduction of heat generation also make the light decay of outdoor LED electronic screens smaller for long-term use.
