LED displays belong to electronic products, and some of the main materials are combustible, which can easily trigger fire. So how do we prevent and do fire work on LED screens?
The fire performance of LED display depends on the quality of the fire-proof material and the box body. The fireproof material mainly includes the wire material, power supply, external protective structure fireproof material and plastic package.
First, In the application of most LED displays, 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.
Second, through the power of the UL certification product 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.
Third, in full color LED display to the material aspect of the outer protective structure, high fire rating on the market of LED display products are mostly used fire 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 ℃, the decomposition temperature of 300 ℃ or higher, environmental performance, low smoke zero halogen, etc. General of the outdoor LED 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 into the screen body internal cause short-circuit fire electronic components.
Forth, full-color LED display, fire prevention materials and an important part of the 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.
Tips: use high quality power, wire, IC, connector and other devices to reduce the failure rate and control the fire probability of LED display. 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 LED display from being fired due to the surrounding fire hazard.
