In the cold winter, the temperature also becomes dry, so in winter the whole color LED screen fire prevention work. The fire protection technology of the display screen is mainly related to the fire-resistant raw materials and the box technology. Fireproof raw materials mainly include the use of wire, power, external protective structure and plastic package for the inside of the display.
1. In most display applications, the larger the unit area of the display screen, the larger the power consumption, and the higher requirements for the electrical stability of the wire.
2, through the UL certification of power supply products is the best choice when choosing a similar products, its effective conversion can guarantee safety and stability of power load, under the condition of the external environment temperature hot, also can work normally.
3, in full color LED display to the material aspect of the outer protective structure, high fire rating display on the market are mostly adopt fire prevention aluminum-plastic plate, its excellent fire resistance, fire retardant sex is extremely strong, core material is special oxygen aging resistance is strong, melting point temperature 135 ℃, decomposition temperature of 300 ℃ or higher, environmental performance, low smoke zero halogen, etc. General outdoor display products of aluminum-plastic plate with high temperature, the rain cold and hot shock aging faster, in the more humid climate season, the rain easily penetrate into the screen body internal cause short-circuit fire electronic components.
4, full-color LED display, fire prevention materials and an important part, it is plastic package, plastic package is primarily a unit module mask pan, the use of materials is mainly use the raw material which has the function of flame retardant PC + glass fiber materials, not only has the function of flame retardant, better when under high and low temperature, and long-term use, not deformation, not brittle cracking, combined with good sealing glue used at the same time, can effectively block the external environment of rainwater in internal that cause a short circuit fire.
Belongs to electronic products due to the LED electronic display, full-color LED display price of the main part of the materials also belong to fuel, using high quality power supply, wire, IC, connecting device, such as flammable components, reduce the failure rate, and control the LED display fire probability; In technology, the installation of LED display screens must be installed, guided, and checked by professionals. The flammable and combustible materials around the LED display are cleared to prevent the fire from the whole colored LED display due to the surrounding fire hazards
