Cold winter season outdoor LED display installation should pay attention to the link
For the outdoor LED display, due to the special outdoor environment, it must be treated differently from the ordinary indoor LED display. Especially in the cold winter season, factors such as low temperature, rain and snow, etc. are also very likely to affect the installation of LED outdoor display. Six notes for outdoor LED display installation: 1. Install lightning protection devices on the display and buildings. The main body and the outer casing of the display are well grounded, and the grounding resistance is less than 3 ohms, so that the large current caused by lightning can be released in time; the display screen may be attacked by strong electric current caused by lightning. 2. LED display itself waterproof measures The screen body and the joint between the screen body and the building must be strictly waterproof and leakproof; the screen body should have good drainage measures, and the water can be discharged smoothly once the water accumulation occurs; pay attention to waterproof and moisture. The display screen is installed outdoors, often exposed to the sun and rain, the wind blows the dust cover, and the working environment is bad. If the electronic equipment is wet or seriously damp, it may cause a short circuit or even a fire, causing malfunction or even fire, resulting in loss; 3. Circuit chip selection Industrial-grade integrated circuit chips with an operating temperature between -40 ° C and 80 ° C are selected to prevent the display from starting due to low temperature in winter. 4. Install ventilation equipment so that the internal temperature of the screen is between -10 °C and 40 °C. The axial flow fan is installed on the back of the screen body to discharge heat; when the display screen is working, it must generate a certain amount of heat. If the ambient temperature is too high and the heat dissipation is poor, the integrated circuit may not work properly or even be burnt, thus making the display system impossible. normal work; 5. Must use ultra-high brightness LED In order to ensure long-distance visibility in the case of strong ambient light, ultra-high brightness LEDs must be used; contrast is increased. The audience is wide, the distance between the line of sight is long, the field of vision is wide, and the ambient light changes greatly, especially if it is exposed to direct sunlight. 6. Display medium selects new wide viewing angle tube The viewing angle is wide, the color is pure, and the color is consistent. The outer packaging of the display medium is more than 100,000 hours. The outer packaging of the display medium is the most popular square-shaped cylinder with the cover, the silicone seal and the metal-free assembly; the appearance is exquisite and beautiful, and the structure is durable. It is protected from direct sunlight, dust, water, high temperature and short circuit. In the cold winter season, it brings certain difficulty to the installation of outdoor LED electronic display. The six major items in the installation process involve the future use and safety of the product, and must be treated strictly.
