"Lehman Optoelectronics: Outdoor LED" Protective Shield "for Abnormal Weather"

Recently, extreme weather has occurred frequently across the country, posing severe challenges to the stable operation of outdoor LED display equipment. The Sichuan, Shaanxi and Chongqing regions have encountered continuous high-temperature roasting tests. The temperature in Chongqing has exceeded 40 ° C for five consecutive days, and the sauna day barbecue day mode has remained online. At the same time, many places in North and South China have experienced concentrated heavy rainfall, and some areas are also accompanied by short-term strong winds. Under the intertwined climate, many outdoor LED displays have experienced faults such as flashing screens and blurred image quality, which seriously affects the use effect and equipment life.
作为深耕 LED 显示领域 21 年的资深企业，雷曼光电始终将产品品质与运行稳定性置于核心位置。Based on years of practical experience in dealing with complex climates and product technology advantages, we have compiled a comprehensive set of outdoor LED display operation and maintenance suggestions for our customers in response to the current abnormal weather to help your equipment smoothly tide over the climate challenge period.
High temperature environment is an invisible threat to outdoor LED displays. Continuous high temperatures can easily lead to the attenuation of the luminous efficiency of LED chips and color cast. It will also accelerate the aging of components and shorten the service life of equipment.
高温环境是户外 LED 显示屏的 "隐形威胁"—— 持续高温易导致 LED 芯片发光效率衰减、色彩偏色，还会加速元器件老化，缩短设备使用寿命。Lehman Optoelectronics 'LED products overcome the high temperature problem from the source of design: using high-temperature resistant materials and optimized circuit layout, they can operate stably in a wide temperature environment of-20 ℃ to 50℃, calmly coping with extreme high temperatures.
此前，雷曼光电为马来西亚 PAVILION 购物中心打造的 1250㎡超高清裸眼 3D 屏，便是耐高温性能的典型案例。The screen is located in the hot tropical climate of Southeast Asia all year round, but it always maintains bright picture quality, dynamic and smooth operation, and is not affected by the high temperature environment. For the current high temperature weather, we recommend that you:

1. Regularly check the cooling system: ensure that the cooling channels of the outdoor large screen are free of dust and debris blockages, and ensure that cooling fans, cooling fins and other components work normally;

2. Enable the intelligent monitoring function: With the help of the Lehman intelligent monitoring system, the internal temperature of the large screen can be monitored in real time. When the temperature is low in winter, the system will automatically turn off the air conditioner to save energy; When the summer temperature exceeds the preset threshold, the balanced cooling mechanism will be automatically activated to ensure the cooling effect while not affecting the display quality;

3. Relying on energy-saving advantages to reduce load: Lehman products have industry-leading energy-saving characteristics, and their operating energy consumption in high temperature environments is 30%-40% lower than the industry average. It can greatly reduce circuit load during long-term use and reduce the risk of failure.​

The strong winds brought by typhoons may exceed the wind pressure limit of the screen, and the leakage of heavy rain may easily cause a short circuit in the circuit. Under the dual threat, outdoor LED displays face severe challenges.
台风带来的强风可能超出屏体风压承受极限，暴雨渗漏则易引发电路短路，双重威胁下户外 LED 显示屏面临严峻考验。Lehman Optoelectronics has strengthened its protection capabilities in all aspects from structural design to performance testing: the outdoor LED display adopts an integrated waterproof structure with a protection level of IP65 and above, which can effectively isolate rainwater intrusion; at the same time, it can withstand the impact of a 12-level typhoon to ensure structural safety in extreme weather.
位于广州的新大新 1200㎡超高清裸眼 3D 曲面屏项目，便是雷曼防护设计的 "实战标杆"。Since the screen was put into use, it has experienced many heavy rains and typhoons, but it has always maintained stable operation without any faults. Based on this experience, we give the following emergency suggestions:

1. Pre-typhoon inspection: Check the firmness of the screen installation structure in advance, clean up the drainage channels around the screen, and avoid stagnant water flowing back;

2. Post-heavy rain treatment: Check the sealing performance of the equipment promptly after the rain. If the screen is found to be wading, cut off the power immediately and contact professional maintenance personnel or manufacturers for handling. Do not disassemble it yourself to prevent electric shock or secondary damage;

3. Special maintenance guarantee: Lehman's professional after-sales team can provide quarterly regular maintenance services, and special inspections can also be arranged before the typhoon season, focusing on checking for the aging of waterproof strips and key aspects such as lightning protection module functions to eliminate hidden dangers in advance.​

In addition to dealing with extreme weather, scientific daily and long-term maintenance are equally important, which can effectively reduce the probability of equipment failure and extend service life.
除了应对极端天气，科学的日常与长期维护同样重要，能有效降低设备故障概率，延长使用寿命。
（一）日常维护建议

1. In normal weather, it is recommended to turn on the machine at least twice a week, and each time it turns on the machine for no less than 2 hours to avoid moisture or performance degradation due to long-term idle use of components;

2. When the environmental humidity is greater than 90% RH, it is necessary to ensure that the machine is turned on every day and the machine is turned on for no less than 2 hours each time. The internal humidity is reduced through the heat generated by the operation of the equipment;

3. If the display has not been used for two consecutive weeks, preheating operation needs to be carried out before starting again. Wait until the equipment temperature stabilizes before running normally to prevent excessive temperature differences from damaging components.​

（二）长期维护建议

1. Conduct a comprehensive inspection of the display screen and peripheral equipment (such as controller, power supply, etc.) every quarter to ensure that all functions are normal and replace aging parts in a timely manner;

2. Develop the habit of backing up configuration files and operating data regularly. If the equipment fails, settings can be quickly restored to reduce downtime losses;

3. Establish an equipment operation ledger to record in detail the operating status, fault conditions and treatment results after each abnormal weather, so that the after-sales team can analyze potential risks;

4. Actively participate in regular user training organized by Lehman, master basic troubleshooting and emergency response skills, and respond quickly when encountering small problems;

5. It is recommended to sign an annual maintenance agreement for key projects. Lehman's after-sales team will customize personalized maintenance plans based on the climate characteristics of the project location (such as increasing waterproof testing in rainy areas and strengthening heat dissipation in high-temperature areas) to ensure equipment operation in all aspects.​
