Green environmental protection has become one of the main themes in modern times, social in progress, but the pollution of environment is in the constantly expanding, so human have to protect our home, and today, all walks of life are also made in advocate green environmental protection products, then LED to enterprise how to develop design won't produce LED display
, light pollution and waste of electricity energy that has become an essential part of the production enterprises must solve the product performance.
LED display has been widely used in city street corner, has become a kind of unique logo to promote the image of city, but it to beautify city image at the same time, the screen body strong light night life of urban residents also caused some negative effect.
Created while the LED industry is a 'light' in the industry, the display 'light' this right, but from the urban environment pollution indicators to measure, it has become a new type of pollution 'light pollution'.
As an enterprise should, therefore, should pay attention to in the production of 'light pollution' problem, should control good brightness Settings.
The first kind of control method: using can automatically adjust the brightness adjustment system.
Based on day and night, environment and time in different locations, the display brightness slightly change will produce a great result.
If the LED display brightness fifty percent of brightness is greater than the environment, we can clearly feel the eyes, also caused the 'light pollution'.
So we can use outdoor brightness acquisition system, at any time of the acquisition of environmental brightness and use data and display control system by receiving system through the software automatically converted to suitable to broadcast the brightness of the environment.
The second kind of control method: multi-level gray scale correction technology.
Ordinary LED display system consists of 18 bit color display hierarchy, the excessive, so in some low gray scale and color color will display very stiff, therefore can cause color light does not adapt.
And new type of LED large screen control system USES is 14 bit of color shows level, greatly improve the colour on the excessive hardness, that make people feel when watching the color soft, avoid discomfort about light.
In terms of power consumption, while using luminescent material is energy-saving LED display itself, but some need to be used in the display area is larger, due to the long time use, the overall power consumption still is bigger, because it need higher brightness, under the action of these comprehensive factors, the display of power consumption is quite amazing, so advertising owners all bear the electricity will be geometric growth.
LED display manufacturers, therefore, enterprises can save energy through the following five: (
Can through the adoption of high photosynthetic efficiency, LED light emitting chip not cut corners;
Adopt high efficiency switching power supply, greatly improve the power conversion efficiency;
To design excellent screen body heat, reducing the fan power consumption;
Overall circuit scheme of design science, reduce internal circuit power consumption;
According to the external environment changes, automatically adjust the brightness of outdoor display screen, so as to achieve the effect of energy conservation and emissions reduction source: LED screen is the search LED network under 3 matters needing attention in a LED display
