Conventional LED display screen VS energy-saving LED display screen
Reducing energy consumption and promoting green environmental protection is currently an important development direction in the LED display industry technology. Outdoor environmentally friendly and energy-saving LED displays reference cutting-edge design concepts from the international community, consider various cost factors, and finally innovate and design low power consumption from three aspects:
1、 Energy saving design of wireless modules
The design technology is mainly based on the latest LED wireless modules and constant current drive chips to drive the design of high luminous efficiency LED tubes.
(1) The latest LED wireless module image design and low energy consumption LED lamp selection: Environmentally friendly and energy-saving LED wireless module pixel images are generally composed of a single pixel combination, with a maximum pixel power consumption of 300w/㎡. The physical density can reach up to 40000 points per square meter. The current is linearly proportional to the brightness of the light spot. By using high-density and low-energy consuming device groups, the power consumption of LED tubes is as low as 50% compared to ordinary LEDs, and the pixel power consumption of display screens is relatively small. When the pixel brightness of the display screen remains uniform, the power consumption of the wireless module of the LED energy-saving display screen will be reduced to over 20%. Therefore, adopting environmentally friendly LED display devices with high light spot efficiency and high intensity and brightness value can achieve effective energy conservation.
(2) Efficient constant current drive circuit design: Traditional LED display components use a 5V power supply to drive the dot matrix module, which divides the voltage onto the constant current drive circuit IC.
2、 Energy saving design of LED environmental protection and energy-saving led screen control system
The LED energy-saving display screen includes computer hardware and system software, and in the media editing platform of the LED energy-saving and environmental protection display screen system, it provides video as an image signal source for the LED energy-saving and environmental protection display screen; It is also a monitoring platform for LED energy-saving systems. Properly regulate various software and hardware of the system from the perspective of environmental protection and energy conservation, in order to achieve system energy conservation:
(1) According to the current power consumption requirements feedback from actual operations, balance control is carried out on the three way cross power supply components of the paired hardware;
(2) Achieve time efficiency rate management of LED display pixels;
(3) Realize the rational control of display brightness in the environmental program.
3、 Energy saving design of module power supply
The outdoor LED energy-saving and environmentally friendly display screen adopts high efficiency, with PFC synchronous circuit design for power supply, which greatly improves pixel power, reduces heat energy consumption, and effectively converts the energy of the switching power supply. It is a bus power supply method with parallel output of low-voltage high current switching power supply modules. Due to low power factor and high copper loss in transformers, the overall power conversion efficiency is low (only up to 75% at full load). The energy conversion efficiency of modular switching power supply is over 86%, which is at least 20% more energy-efficient than that of conventional power supply. The advantages of adopting the above measures for outdoor LED energy-saving and environmentally friendly display screens with low power consumption include four aspects:
(1) Saving electricity costs; The reduction of operating costs.
(2) Reduce the temperature of the display module; Reduce investment in heat dissipation equipment;
(3) Reduce display screen power consumption, reduce investment in cables and power capacity expansion
(4) Delaying LED attenuation speed, reducing temperature drift of display screen photoelectric parameters, stabilizing image effects, improving system reliability, and extending display screen lifespan. Compared with conventional LED display screens, outdoor LED energy-saving and environmentally friendly display screens not only reduce the investment of heat dissipation equipment and delay LED attenuation speed, but also achieve an energy-saving rate of 25-50%. The benefits are significant. Compared with P10 outdoor surface mounted full color display screens, traditional LED display screens consume 1000W of electricity per 100 square meters and 100KW of electricity per hour
