LED fire solution thinking

Late last year, the guangzhou baiyun airport electronic screen, fire losses; Recently, and the WCBA venues in Beijing from a particular brand of LED display burn out smoking news, industry wide attention again, also have to cause our thinking. How to effectively avoid the LED display is on fire, improve product safety and stability of this problem, before all the LED display supplier.

the first LED display the cause analysis, power supply wire on the market of wire rod quality is uneven, many spools for copper clad aluminum wire, appearance looks like copper wire, actual it is aluminum alloy wire; This line is commonly used in temporary thread, simply cannot be used for regular products. Copper and copper wire, insulation, wire diameter size problem ( The high-power 1 general requirements according to the display screen. More than 2 times) As long as one of neglect, these questions, will be buried hidden trouble, bring after big disaster;

2, power reference inferior power, or to use the power of the maximum rated power, resulting in long-term overload power ( Only commonly used power supply 70% of the rated power) As power cords, terminal inferior and contact sturdiness, these can be the cause of the fire hazards induced;

the third, the PCB itself inferior material, copper clad slants thin, unreasonable design, craft is poor in copper wire, such as burr phenomenon will produce a short circuit will become the source of fire hazard;

4, the cooling system. LED display working under high temperature, heat dissipation problem becomes the first need to solve the problem. Such as the cooling air duct design is not reasonable, easy to cause the dust accumulation on fan main shaft, power supply and main board, causing poor heat dissipation, electronic short circuit, fan stuck, causing a fire.

5, service and maintenance. On the one hand is display suppliers no systematic training for customers, leading to operation is not standard. The other that is not to have sold LED display screen suppliers for regular maintenance, late or not careful not timely maintenance, lead to fail to find anomalies.

based on the analysis of the cause of the fire in LED display and thinking, the new Asia wins photoelectric out special fire protection solution to share with you.

a, new Asia - independent research and development of optoelectronic integrated within the production of LED display cabinet, display, drive and receive integrated one, simplify the internal structure, only an external power and signal lines, from the source to eliminate the hidden line aging or damaged cause a short-circuit. The power cord has been used domestic famous brands and through the national 3 c compulsory certification of copper core, leaving enough space on the power to use, to display open running current biggest 1. 2 times to determine the wire diameter, so give enough protection on online diameter;

2, power supply we use exclusive custom power supply, the all materials strict control and screening. The power rating size is 1 case full power. 4 times. Normal power supply at 50 ℃, the efficiency will decline to 70%, and our power supply can still has 100% efficiency.

3, PCB. Use 4 layer board design, wiring strictly according to the standard, IEC/EN/UL60950 maximum thickness up to 4 oz copper. For PCB incoming inspection, we have a professional IQC team and improve the incoming inspection process and ensure that every piece of PCB zero burr, effectively prevent safety problems because of the PCB short circuit.

4, turbine cycle heat dissipation design and manufacturing technology, fire wall type of safety barriers. New Asia - photovoltaic research and development production of LED display USES the turbine circulation cooling system, when the power supply when the temperature of 50 ℃, the turbine cooling system, automatic start and outdoor fan start can adjust freely according to the use of the environment. At the same time, the control box lid for large area whole aluminum fins cover board, power supply directly installed in the above, the heat can be directly exported to, greatly improve the heat dissipation effect. Science of heat dissipation design and sophisticated manufacturing technology for the product increases the fire wall type of safety barriers.

5, the reliability of the products through rigorous testing we have in the industry the most complete laboratory and the largest training center. From raw materials, and the whole production process, we have strict quality system control, the company laboratory run 24 hours, sampling test for each batch of material; Each link has self-checking system and security system, and timing of each post personnel do operation specification and quality awareness training and examination.

6, systematic service mechanism, avoid the caused by improper operation, maintenance is not timely safe hidden trouble. New Asia photoelectric has established the systematic service mechanism, in product sales, to provide specification, careful operation training service, the daily operation specification. If customers have special requirements, new Asia - photoelectric will provide professional and technical personnel on-site support for installation. Project to install 1 months later, the new Asia wins photoelectric telephone pays a return visit regularly, found the abnormal situation in time, and resolved. Major activities held by the customer, we can send technicians to escort the scene. From maintenance training and post to the scene, a dragon service mechanism, avoid the improper operation or maintenance is not timely and safe hidden trouble.

7, authority and safety certification, strictly the quality pass. New Asia wins and photoelectric products passed the ISO9001:2008 quality system certification, CCC, CE, FCC, TUV certification, and implementation of full, comprehensive quality management, implement rigorous quality control process, never expect shipment controlled every link, do not accept, don't make, not out of bad product.
