The characteristics of outdoor LED display
Since its appearance, LED display screens have been valued for energy saving and environmental protection. LED is synonymous with energy saving. Compared with traditional lighting products, the energy-saving advantages of LEDs are quite obvious and outstanding. In the near future, there is a trend to replace traditional lighting with full power. The following editors will introduce the characteristics and installation precautions of outdoor LED display, let's take a look.
Characteristics of outdoor LED display
Since its appearance, LED display screens have been valued for energy saving and environmental protection. LED is synonymous with energy saving. Compared with traditional lighting products, the energy-saving advantages of LEDs are quite obvious and outstanding. In the near future, there is a trend to replace traditional lighting with full power.
With the increasing environmental awareness of people all over the world, we can hear low carbon, energy saving and emission reduction everywhere, and can feel the efforts made by people for environmental protection: urban electric taxis; LED street lights; solar + wind energy street lights; no Fluorine refrigerators and air conditioners are the most real feelings in our lives.
The luminescent material used in the LED display itself is an energy-saving product. However, since the area of ​​the outdoor display screen is generally large, the power consumption is still large. In response to the World Energy Organization's call and the long-term development interests of the industry, many outdoor LED display manufacturers have launched more energy-saving and low-carbon outdoor LED display products. Their power consumption is more than that of previous display screens. Great improvement.
Outdoor LED display, due to the great changes in ambient brightness during the day and night, we can achieve the effect of energy saving and emission reduction by automatically adjusting the brightness of the outdoor LED display.
Precautions for outdoor LED display installation
1. Lightning protection measures for installation of buildings and screens
In order to prevent the display from being subjected to strong electromagnetic attacks caused by lightning, the screen body and outer protective layer of the display must be grounded, and the resistance of the grounded line should be less than 3 ohms, so that the current caused by thunder Is drained from the ground.
2. Waterproof, dustproof and moisture-proof measures for the entire screen
The connection between the box body and the box body, and the combination of the screen body and the force installation object should be seamlessly connected to avoid water leakage and moisture. There must be good drainage and ventilation measures inside the screen body, and if there is water accumulation inside, it can be dealt with in a timely manner.
3. About the choice of circuit chip
In the northeastern part of China, the temperature in winter can generally reach minus ten degrees Celsius, so when choosing a circuit chip, you must choose an industrial-grade chip with a working temperature of minus 40 degrees Celsius, which means 80 degrees Celsius, to avoid the occurrence of excessive temperature. Low causes the display to fail to start.
4. Ventilation measures should be done inside the screen
A certain amount of heat will be generated when the screen is powered on and working. If the heat cannot be discharged, and it accumulates to a certain degree, it will cause the internal environment temperature to be too high, which will affect the operation of the integrated circuit. Seriously, it may cause burnout. The display cannot run. Therefore, the ventilation and heat dissipation measures inside the screen body must be done, and the temperature of the internal environment should be kept between minus 10 degrees and 40 degrees.
5. Selection of highlight wick
The high-brightness LED tube is selected, which allows us to display well under direct sunlight, and also enhance the contrast with the surrounding environment, so that the audience of the picture is wider, at a far distance, and a wide viewing angle. Locally, there are still good performances.
Outdoor LED display media is the development trend of the advertising industry in the 21st century. It is an indoor and outdoor advertising display device with audio and video functions. It is an internationally leading high-tech product. The appearance of this type of equipment is novel and unique, and its area can be adjusted at will. It can not only broadcast audio and video advertising programs, but also can install fixed light box advertising spaces on all four sides. Currently, local governments are encouraging the use of outdoor LED screens, and the approval of canvas ads and light box ads .
