Environmental protection and Energy LED Display is a collection of electronic technology, computer technology, electrical technology, optical technology, Green Environmental protection to reduce light pollution and low power consumption and other international advanced engineering Technology Integration of the system engineering applications, large engineering area, longer screening time, low electricity consumption has become a key indicator of user Concern. Reduce energy consumption green environmental protection is LED Display Screen industry technology at present an important direction of development, outdoor environmental protection and energy-saving LED Show The screen refers to the international cutting-edge design concept, taking into account all aspects of cost factors, and finally from three aspects of low-power innovation and Design:
one, the Wireless module energy-saving design
Can design technology mainly according to the latest led wireless module, Constant Current Drive Chip to drive the high-efficiency LED tube design carried Out. (1) The latest LED Wireless module screen design and low energy consumption LED lamp selection: environmental protection and energy-saving led wireless Module pixel screen Universal single pixel combination, pixel point maximum power consumption is: 300w/㎡. physical density up to 40,000/㎡. the current and light point luminance are linearly proportional. Using high-density and low-energy device groups, LED lamp point power consumption compared to ordinary LEDs as low as 50%, the display pixel power consumption is relatively small. In the case of the display pixel brightness uniformity, the LED energy-saving display of the wireless module power consumption will be reduced to more than 20%. thus, the use of high light point efficiency, strong luminous value of the green LED Display To achieve effective energy savings. (2) High-efficiency constant Current drive circuit design: led traditional display module using 5V power supply to drive the lattice module, voltage divider to the constant current driver circuit ic, to exclude the constant current circuit chip to reach the linear conduction of the necessary positive voltage power, the other remaining voltage conversion to heat is caused by unnecessary consumption. LED energy-saving and Environmental protection display components Pixel-point constant current drive circuit, designed to take the Unit-type led device decentralized power supply mode: cell devices also use the latest technology energy-saving Low-voltage energy-saving driver Ic.
After many tests have proved that in the use of the same class of energy-saving constant current drive chip led components, and the need to display the same situation, energy-saving wireless module compared to the traditional model of energy saving more than 20%.
second, energy-saving design of LED environmental protection and energy saving display control system LED environmental protection and energy-saving display including computer hardware and system software, and in the LED Energy-saving and environmental protection display system of media editing platform, to the LED Energy-saving environmental protection display video for image signal source; is also the LED energy-saving system monitoring platform.
From the angle of environmental protection and energy saving appropriate control system of various hardware and software, so as to achieve system energy:
(1) according to the actual operational feedback of the current consumption requirements, paired with the hardware of the Three-power cross-supply components for equalization control;
(2) achieve the time into the efficiency of management LED display pixels;
(3) to achieve the environmental procedures of this rationalization control display BRIGHTNESS.
three, Module Power Saving design Outdoor LED energy-saving and environmental protection display using high efficiency, with PFC synchronous circuit design power supply so greatly improve the pixel power, reduce heat consumption so that switching power supply energy to be effectively converted Efficiency. is a low-voltage high-current switching power supply module output Parallel bus power supply Mode. Due to the low power factor, transformer copper loss, The entire power conversion efficiency is low (full load can only be achieved within 75%). Module switching power supply Energy conversion efficiency of more than 86%, efficiency is the conventional power conversion rate of energy saving is at least 20%.
Take the above measures outdoor led energy-saving Environmental protection display low power advantage has 4 aspects: (1) savings in electricity cost;
Reduction in operating Costs. (2) reduce the Display module temperature;
Reduce the input of cooling equipment;
(3) reduce the power consumption of the display, reduce the input of cable, power increase capacity (4) delay the LED attenuation speed, reduce the temperature drift of the display photoelectric parameters, stabilize the image effect, improve the system reliability and prolong the display Life. Outdoor LED energy-saving and environmental protection screen compared with the conventional led display, not only reduce the input of the cooling equipment, delay the LED attenuation speed, and the energy saving rate of 25%-50%, the benefit is significant to P10 the appearance of the full color screen control, in order to 100㎡ the outdoor P10 surface stickers full-colour display to calculate, Traditional LED display 100㎡ power consumption of 1000W, electricity consumption per hour of 100KW, according to a 1 yuan of electricity, 100 yuan per hour electricity costs. According to daily average illumination of 10 hours to calculate, the daily cost of 1000 yuan of Electricity. The same 100㎡p10 surface stickers energy-saving display, The average energy savings of 40% per 100 square meters of power consumption of 545W per hour screen consumption can be 54. 5KW, According to a once electricity 1 yuan calculation, hourly electricity cost 54.
5 yuan, According to the traditional advertising screen lighting 10 hours a day, the cost of 545 yuan per day to spend on Electricity. You can see that energy-saving display can save 455 yuan a day electricity, energy-saving display annual electricity savings of 161980 Yuan. If the screen age is used for 6 years then this 6 years can save 971.
880 yuan, so that the cross-sector industry chain is rushing to cascade and accelerate the application Layout. Energy-saving LED display vs Conventional LED display | Not only energy saving but also save money
