For outdoor LED displays, it is used outdoors. Therefore, it is inevitable to treat it differently from ordinary indoor LED displays. Outdoor LED display installation requirements are also different from ordinary indoor LEDs. It must be done in detail on the installation. Otherwise it is very likely to cause trouble.
There are six ideas for installing an outdoor LED display:
1. Lightning protection devices are installed 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. Waterproof measures for LED display itself
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 the ventilation equipment to cool down, 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 under strong ambient light conditions, ultra-high brightness LEDs must be used; contrast ratio is increased. The audience is wide, the line of sight is far and the field of view is wide; the ambient light varies greatly, especially in direct sunlight.
6. Display medium adopts 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.
The installation precautions for outdoor LED electronic display involve the future use and safety of the product, and must be treated strictly.
