This kind of box appeared in the early stage of LED industry development, and it was slightly larger and heavier. The sizes of iron LED display boxes are 1280mm×960mm, 960mm×960mm, 768mm×768mm, etc. Iron boxes can be divided into sealed boxes and simple boxes. Sealed led boxes are more expensive than simple boxes of the same size.
1, the protection level of sealed led box can reach IP65, and it can work normally in all kinds of environments, mainly used outdoors.
2, simple LED display box, relatively simple workmanship, mainly indoors.
Second, die-casting aluminum LED box
Die-casting aluminum box has the advantages of light weight, reasonable structure and high precision, and can realize seamless splicing. At present, it basically occupies the indoor and rental LED display market. The die-casting aluminum LED box has been optimized and updated in terms of structure and performance. It is a patented compact rental display screen with high splicing accuracy and convenient disassembly and maintenance. The following five clock boxes were introduced:
1, indoor die-casting aluminum 480mm×480mm box.
The LED display box of this size has high strength, high precision, single weight of 9KG, strong versatility and convenient upgrade. The same model supports P 1.6P2.5P4P4.8P5 rental display models.
2. Indoor die-casting aluminum 500mm×500mm box
The LED display box of this size is opened separately, which makes it easier to cooperate with most modules at present and is closer to the user's personal customization. Deeply favored by domestic and foreign customers, the same paragraph supports P3.91P4.81P4P6.944 rental LED display models.
3. Indoor die casting aluminum 5 12mm×5 12mm box.
The die-cast aluminum LED display box of this size is formed separately, which is easier to cooperate with most of the current modules and closer to the user's personal customization.
4. Indoor die-casting aluminum 576mm×576mmLED box.
The die-cast aluminum box with this size is light in weight and convenient to install, and can realize two installation methods: stacking and hoisting. It occupies a large share in the indoor LED display and rental LED display market. The same paragraph supports P3P4P6 rental LED display model.
5. Outdoor die-casting aluminum 640mm×640mm box.
This size die-cast aluminum LED display box is mainly used for renting LED display screens outdoors, and the same model supports P6.67P8P 10P 16 rental LED display models.
Three. Magnesium alloy light emitting diode box
Magnesium alloy is an alloy based on magnesium and added with other elements. Its characteristics are: low density, high specific strength, high specific elastic modulus, good heat dissipation, good shock absorption, greater impact load bearing capacity than aluminum alloy, and good resistance to organic matter and alkali corrosion. Magnesium alloy used as LED box has high cost performance, convenient installation and good heat dissipation, which makes the product have more market advantages.
Fourth, high-tech material LED box
There are two main materials: nano-polymer and carbon fiber. At present, these two LED boxes are not popular, and only a few LED display manufacturers are using them.
1, nano-polymer LED box
It has the characteristics of impact resistance and falling resistance, and its weight is much lighter than that of conventional boxes. The weight of a single box is only about 5KG. Moreover, the price is lower than that of die-casting aluminum box, and it is simple to assemble and disassemble and portable; Save money, truss cost and transportation cost are low.
2, carbon fiber LED box
The appearance of carbon fiber boxes has solved the problem that LED display screens cannot be installed in some sites due to load-bearing restrictions and rigging restrictions. Carbon fiber box is characterized by ultra-thin, light weight, good strength and high tensile strength. Moreover, it adopts fully modular design, which is more convenient for maintenance. The 45-degree right angle edge can realize the 90-degree splicing installation of the screen body.
