Insufficient heat dissipation of the display. PCB burns and catches fire. Wires are messy and prone to short circuits and fires. Wires are exposed, which poses a high risk of electric shock. The power supply is not selected or installed in a standardized manner. The above are main reasons lead to fire accidents. The frequency occurrence of fire accidents in LED displays makes it clear that the research and development of new products that are resistant to high temperatures should be taken seriously.
According to these situations, we developed a pure aluminum cabinet and module cabinet.
1. Selection of flame retardant materials
Using flame-retardant PCB boards (such as FR-4 flame-retardant materials) in LED modules can effectively prevent fires in the circuit. Using flame-retardant wires that meet fire protection standards can reduce the risk of fire caused by short circuits or overloads. Using fire-retardant glue in module packaging can prevent the glue from burning at high temperatures.
2. Sealing structure design
Sealing design: The box adopts a high-precision sealing design to prevent external fire sources from entering the interior, while reducing oxygen circulation and reducing the possibility of combustion. Insulation layer: Add insulation materials (such as ceramic fiber or fireproof cotton) inside the box or key parts to block the impact of external high temperature on internal components. Heat dissipation design: By optimizing the heat dissipation structure (such as heat sink, fan, etc.), the temperature inside the module and box is reduced to reduce the risk of fire caused by overheating.
3. Electrical safety design
Overload protection: Overload protection devices are installed in the power supply and circuit to prevent fire caused by excessive current. Short circuit protection: Use power supplies and driver ICs with short circuit protection functions to avoid fire caused by short circuits. Grounding protection: Ensure that the box and module are well grounded to prevent static electricity accumulation or leakage from causing fire.
4. Comply with fire protection standards
Certification requirements ensure that the modules and cabinets comply with international or industry fire protection standards (such as UL94, RoHS, etc.) and pass relevant fire protection certification.
1. Energy Saving
Common cathode technology attaches LED chips directly to PCB boards, eliminating the brackets and wire bonding in traditional SMD packaging, thereby greatly improving pixel density. This enables screen displays to achieve higher resolutions and is suitable for applications with extremely high image quality requirements.
2. IP65 High Waterproof Level
The power supply box is equipped with a waterproof air venting calve, which ensures the balance of air pressure inside the power supply box and prevents moisture from entering the box. What’s more, circuit boards and electronic components are coated with conformal coating. In addition, Using waterproof plugs for power and signal cables.
3. Excellent heat dissipation performance
Thick and high silver containing heat sinks. PCB board directly be in touch with aluminum power box. Special cabinet design effectively reduces the operating temperature of the chip and extends the service life of the display.
4. Conformal Coating
It is a special coating used to protect electronic circuit boards. It has moisture-proof (waterproof), corrosion-proof and dust-proof functions. It is widely used in electronic equipment, especially those used outdoors or in harsh environments. It is suitable for coastal cities, places with heavy wind and sand, and places with strong rain corrosion.
5. Wide viewing angle display
The luminous angle of the cabinet display can usually reach more than 140 degrees, and the light is uniform, which is suitable for scenes that require a wide viewing angle, such as shopping malls, exhibition halls and stadiums.
1. It can be installed against the wall, meeting the conditions for front maintenance. For small spacing, use a magnetic suction tool to suck the module from the box for maintenance. How to maintain large spacing? You can use a gear tool to rotate the four holes on the module and take it off.
2. If you are making an extra-large double-sided or single-sided screen, The cabinet is designed to be installed as a column. we will also provide some necessary installation materials and guidance such as connecting pieces.
The fireproof, waterproof and corrosion-resistant properties of outdoor LED displays significantly improve their safety, durability and stability, while reducing maintenance costs. They are suitable for a variety of outdoor scenarios and are a reliable and economical choice.
