(1) Switching power supply selection: Select a switching power supply that can meet the required rated power for actual use, to avoid the actual use of the load exceeds the rated power of the switching power supply, resulting in excessive switching power supply load, causing the switching power supply to burn out and causing ignition.
(2) LED selection: Do not blindly require the screen body to achieve a bright effect, easily lead to aging of the device, reduce service life, and easy to age and catch fire, we choose the LED corresponding to the brightness at the same time, a rich design experience Manufacturers will propose 20% extra margin at the beginning of the design. In this way, the designed modules will have very low current. (P16 static is about 7~8A of the module current, and the average video current is about 2~3A. ), The product is highly efficient, stable, and energy-saving;
(3) Power supply line: Detailed understanding of whether the power supply distribution of the modules in the DC power supply line is balanced, multiple output of the AC power supply line, and whether the output power of each phase is balanced are the causes of the fire of the line.
(4) Box alignment: whether the cabling conforms to the cabling principle and meets the safety requirements.
(5) LED brightness ratio: LED's RGB color selection standard follows the principle of 3:6:1. Many manufacturers use small-sized LED chips in order to reduce the purchase cost of raw materials, which will inevitably lead to the need to improve single-group LED. The current can achieve the effect of white balance and increase the current of the single group color LED, which will lead to the high temperature of the local part of the module, the high temperature and no good heat dissipation measures, and the module will have the phenomenon of inconsistent brightness. The use of time will cause the device to age and catch fire;
(6) Wire rods: Whether the wire rods are national standard wire rods, whether the requirements of the fire and flame retardant of “IEC60332†standard have been passed, and whether the size of the core wire has sufficient margin in practical use.
(7) Potting glue: Whether the material passed the flame retardant requirements of "ULE325549V0" standard.
(8) Key components: Whether the temperature of critical components in the heat can be maintained at a reasonable level during prolonged use.
(9) Kit: Whether the material passes the fire retardant requirements of UL94V0. [Editor: ltongled]
