"Energy conservation and emission reduction" means to save energy and reduce energy consumption. As an important part of the manufacturing industry, LED display industry "energy saving" is also the topic that LED display manufacturers have been paying attention to.
At present, many LED display enterprises in the industry are involved in the research, development and production of energy conservation and emission reduction. At present, some energy-saving LED displays on the market mainly improve the energy-saving effect by improving the power supply, which has attracted the attention of many consumers and given them quite high expectations.
This way starts from the power supply. First, the existing LED display screen directly adopts the half-bridge or full-bridge high-efficiency switching power supply, and the synchronous rectification has significant energy-saving effect. The second is to reduce the power supply voltage as far as possible under the condition of constant current driving IC, and to achieve better energy saving effect by separate power supply through the red, green and blue tube cores. Of course, the application cost of this non-standard voltage power supply and new technology is bound to rise. From the screen drive IC, energy saving is not obvious, reducing the drive constant current pressure difference will bring new problems including cost. Part of IC enterprise propaganda drive energy-saving design, is nothing more than a sales strategy.
Then, in addition to energy saving from LED display power, what are the better ways to achieve LED display energy saving?
Compared with other traditional advertising methods, LED display has its own "halo" of energy saving and environmental protection --LED display has self-adjustment function of brightness. Therefore, another aspect is to achieve the purpose of energy saving through brightness adjustment of LED display.
LED displays themselves use light-emitting materials that are energy efficient. However, because the outdoor display screen area is generally large, high brightness, so, the power consumption is still large. However, outdoor LED display, due to the great change of ambient brightness between day and night, LED display brightness needs to be reduced at night, so the brightness self-adjustment function is very necessary.
However, given that LED display screen itself is a natural energy-saving material, but in the actual application process, the display area is usually large occasions, long time running and high brightness playback, power consumption is not to be underestimated. In the application of outdoor advertising, in addition to bearing the costs associated with LED display, the electric bill will increase geometrically with the use of the equipment. Therefore, only the improvement of technology can solve the problem of greater energy saving of products.
