Outdoor LED screens are widely used in a variety of large-scale events, commercial advertising and information release, but the outdoor environment is more stringent requirements for LED screens, so special solutions are needed. This article will introduce the outdoor LED display solutions in detail, including LED beads, shell materials, cooling system, control system and power system.
LED lamp bead selection
Outdoor LED displays need to be bright enough to remain clear in bright light. Therefore, when choosing LED beads, it is necessary to consider their brightness and reliability. Generally speaking, LED beads used in outdoor LED displays should have a brightness of more than 5000cd/m², and need to have long life, high reliability and other characteristics. At the same time, it is also necessary to choose LED beads that can adapt to various climatic conditions, in order to ensure the stability of the display effect.
Choice of shell material
Outdoor LED displays need to be waterproof, dust-proof, impact-resistant and so on, so special housing materials need to be selected. Generally speaking, outdoor LED display shell material uses aluminum alloy or stainless steel and other metal materials, and needs to carry out special waterproof, dustproof and impact resistance treatment. In addition, in order to ensure the stability and durability of the shell, also need to carry out special surface treatment, such as plastic spraying, anodizing, etc.
Design of cooling system
Because the outdoor LED display needs to work stably for a long time, it is necessary to design an efficient cooling system to ensure the normal work of the LED beads and control system. Generally speaking, outdoor LED display cooling system adopts air-cooled or water-cooled, among which air-cooled cooling system is more common. An air-cooled cooling system usually uses a fan and a heat sink to dissipate heat quickly to ensure the stable operation of the display for a long time.
Design of control system
Outdoor LED display requires remote control and monitoring functions, so it is necessary to design an efficient control system. Generally speaking, the outdoor LED display control system uses a combination of PC and control card, PC is used for remote control and monitoring, control card is used to control the brightness and color of LED beads. To ensure the stability and reliability of the control system, you need to select high-quality PCS and control cards, and take special anti-lightning and anti-static measures. In addition, in order to ensure the security of the control system, it is necessary to set password protection and remote monitoring functions to detect and handle anomalies in a timely manner.
Design of power supply system
The power system of outdoor LED display should be stable, reliable and safe to ensure the normal operation of the display. Generally speaking, the power system of outdoor LED display adopts the combination of UPS and regulated power. UPS is used to ensure the stability and reliability of the power supply, and regulated power is used to ensure the stability and safety of the voltage. In addition, you need to take anti-lightning and anti-static measures to ensure the stability and security of the power system.
To sum up, outdoor LED display solutions include LED beads, shell materials, cooling systems, control systems and power systems. By selecting high brightness LED lamp beads, using waterproof, dustproof, impact-resistant shell materials, design efficient cooling system, using stable and reliable control system and power system, we can ensure that the outdoor LED display operates stably under various climatic conditions, and has remote control and monitoring functions. For a variety of large-scale events, commercial advertising and information release occasions to provide high quality services.
