Outdoor fixed led screen how to be more energy efficient

Green environmental protection has become a major theme in the modern era. The society is advancing, but environmental pollution is also constantly expanding. Therefore, human beings must protect our homes. Nowadays, all walks of life are also promoting green environmental protection. Products, then how LED companies can develop and design outdoor fixed LED screen displays that do not produce light pollution and waste electrical energy, which has become an important product performance that manufacturers must address.

Outdoor fixed LED display screens have been widely used in various corners of the city, and have become a unique symbol to enhance the image of the city. However, while beautifying the image of the city, the strong light of the screen also has a certain negative impact on the nightlife of urban residents. influences. Although the LED industry is a “light-forming” industry, the display “lighting” is understandable, but it has been reduced to a new type of pollution “light pollution” from the city's environmental pollution indicators. Therefore, as a company should pay attention to the "light pollution" problem in production, we should control the setting of brightness.

The first method of control: an adjustment system that automatically adjusts the brightness.

Depending on the day and night, a slight change in display brightness can have a significant effect in different locations and time periods. If the brightness of the outdoor fixed LED billboard display is greater than 50% of the ambient brightness, we will obviously feel the eye discomfort, which will cause "light pollution."

Then we can use the outdoor brightness acquisition system to collect the ambient brightness at any time, and use the display control system to broadcast the screen by receiving system data and automatically converting it into a suitable brightness by software.

The second control method: multi-level grayscale correction technology.

The ordinary outdoor fixed led sign LED display system adopts an 18-bit color display level so that in some low grayscales and excessive colors, the color will be displayed very hard, so it will cause the color light to be unsuitable. The new LED large-screen control system uses a 14-bit color display layer, which greatly improves the hardness of the color, so that people feel soft color when watching, to avoid people's discomfort with light.

In terms of power consumption, although the illuminating material used in the LED display itself is energy-saving, some applications need to be applied in a large display area. Because of long-term use, the overall power consumption is still large because of the brightness required. It will be relatively high. Under the influence of these comprehensive factors, the power consumption of the display screen is quite amazing, and the electricity expenses of all the advertising owners will also grow geometrically. Therefore, companies can save energy by using the following five points:

(1) The high-efficiency LED can be used, and the light-emitting chip does not cut corners;

(2) Adopt a high-efficiency switching power supply to greatly improve power conversion efficiency;

(3) Perform excellent screen heat dissipation design to reduce fan power consumption;

(4) Design a scientific overall circuit scheme to reduce the internal line power consumption;

(5) Automatically adjust the brightness of the outdoor fixed led screen display according to changes in the external environment, thereby achieving the effect of energy-saving and emission reduction
