Another important part of the display of fire raw materials, that is, plastic packages, plastic packages primarily use cell module Bottom mask material, the main use of raw materials is PC + glass fiber material with fire-retardant features, not only has the fire-retardant features, more and long-term energy when used at high temperature, deformation, not brittle cracking, combined with better sealing glue to use, can effectively block the rainwater penetration into the interior of the external environment in order to cause a short circuit fire.
In addition to the interior of the raw materials will affect the fire effect, external configuration and design are also very important, but the external configuration of the main problems related to the heat of fire, and it will work in the display configuration exhaust fans and air conditioning for cooling the interior of the screen, cooling, recommended every 8-10 square assembly 1P body temperature to ensure the screen to maintain normal air conditioning thermostat, air conditioning or fan configuration is not in place can cause uneven heat treatment, can easily lead caused due to temperature enhance internal security Screen risks. In response to a thunderstorm, Screen device is to avoid the lightning arrester assault and burn the screen inside the device an essential tool, you can directly import the lightning ground, without affecting the screen body impact.
Wireless LED display control card played a certain role in this propaganda. Wireless LED display control card is a small community guard, can quickly respond to the call, timely broadcast information, but also broadcast weather forecasts. Real-time weather information collected and transmitted to the LED display real-time display, the current time, weather warning signal icon, temperature and humidity and other information; real-time scrolling text information, publishing the latest weather, important information promptly issued a notice to meet meteorological disaster prevention and mitigation information display requirements.
Because LED electronic display are electronic products, the main part of the material also belongs to combustibles, so fundamentally from the start, “precautionary measures in unburned”, the use of high-quality power supply, wire, IC, connecting devices such as flammable devices, reducing the failure rate, and control the probability of fire led display; technical aspects, the led display installation process must be installed by a professional guide, inspect, you can take preventive measures; perimeter led display for easy combustibles, flammable materials cleanup, prevent fire hazards around the fire led to led display; and maintenance aspects, led by professionals regularly monitor to detect and check.
To enter the US market should reach UL48 safety wire and cable, ETL certification, while the British safety certification required by BS, Japan will need to reach PSE mandatory safety certification, while Hong Kong has long been aware of the department, although this international problem.
