LED wall panel: Summer outdoor LED screen cooling
Why do outdoor LED displays need to do a good job of temperature control?
Under different temperature conditions, the brightness attenuation and decline of red, green, and blue lamps are different. At 25 degrees Celsius, the white balance is normal, but at 60 degrees Celsius, the brightness of the three colors all decline. , and its attenuation value is inconsistent, so the whole screen brightness will drop and the color cast will occur.
How to cool down the outdoor LED large screen
At the same time, the working temperature of the LED display screen exceeds the bearing temperature of the chip, which will rapidly reduce the luminous efficiency of the LED display screen, resulting in obvious light decay and damage; the lamp tube packaging material will change to a rubbery shape and the thermal expansion coefficient will rise sharply, resulting in The LED tube is open and ineffective, so the LED display should do a good job of dissipating heat and control the temperature of the screen below 60 °C.
Outdoor LED display cooling method
LED display screen within 20 square meters, choose the appropriate size exhaust fan according to the installation space.
If conditions permit, the LED display screen within 20 square meters can be dissipated by two exhaust fans with a diameter of about 300mm, which is determined according to the size of the installation space.
More than 20 square LED display
Choose the heat dissipation method according to the installation method and needs, install it against the wall, choose the exhaust fan or install the air conditioner according to the size of the area.
If the installation position of the LED display is against the wall, the exhaust fan can be selected according to the size of the area, and the installation position of the exhaust fan is arranged in sequence above the side of the screen. When installing the exhaust fan, make sure that there is a net inside to prevent personal injury caused by wind adsorption. At the same time, aluminum alloy shutters are installed on the air outlet of the exhaust fan on the outside aluminum composite panel to play a waterproof role.
If installing an air conditioner, ensure enough space to place the air conditioner host without affecting the overall appearance of the wall. Generally, 1.5P, 2P and 3P air conditioners are used. Northern cities use 20 square meters of 1P air conditioners; southern cities use 15 square meters of 1P air conditioners. If the area of the LED outdoor display is relatively large, the air conditioner needs to be customized.
Column-type installation, it is best to use an exhaust fan to dissipate heat.
If it is a column-type LED display, it is best to use an exhaust fan to dissipate heat. The exhaust fan is installed on the top of the aluminum-plastic panel on the back of the large screen, and it is made into a shutter to prevent water. If it is an LED display in the form of a double column, several shutters can be opened in the middle of the double column as an air intake, and the exhaust fan above is an exhaust port, which forms a complete air convection and makes the heat dissipation effect better.
Install exhaust fans and air conditioners at the same time, and adjust the heat dissipation method according to the ambient temperature.
The LED display can be dissipated by a combination of exhaust fan and air conditioner. When the temperature reaches above 40°C, the air conditioner is turned on and the exhaust fan is turned off. When the temperature is less than 40°C, the exhaust fan is turned on and the air conditioner is turned off.
If it is required to install an air conditioner, the purchase cost and use cost will increase, and the heat dissipation effect will be better, but the space for the installation of the air conditioner external unit must be considered to ensure the overall aesthetics.Choose high-protection outdoor LED display products No matter which heat dissipation method is used, it is essential to choose LED display products with high performance and high protection. Strong Jucai outdoor surface mount products use advanced lamp surface glue filling technology and spray three-proof paint on the back. Screen is safe!
