Quality has always been a key topic at the two sessions each year. At the Fourth Session of the 12th National People's Congress, which was opened on March 5, when Premier Li Keqiang laid out the main objectives, tasks and major measures during the 13th Five-Year Plan period in the government work report, he clearly stated that "building a quality power", followed by How to speed up the construction of a quality and strong country is being discussed by the deputies and the community. It coincides with the arrival of the 3.15 International Consumer Rights Day in 2016. “Counterfeiting†and “Quality†have once again become hot topics in society.
3.15 For some people, it is really "a few happy couples", happy consumers, what are the unscrupulous black heart manufacturers. Looking at the LED display industry, quality issues are already a commonplace topic, but today, the author once again took it out and said things, because important things need to be said more than three times.
LED is a new energy-saving and environmental protection industry for the benefit of mankind, but it has been criticized by consumers for the quality problems that have been repeatedly exposed. Not only that, the inferior LED display makes the operators miserable, but also seriously affects the healthy development of the industry. It can be described as a "bad" three "injury."
Therefore, both consumers and suppliers should clearly know which aspects of LED display quality problems are relatively large:
First, the wire: the quality of the wire on the market is uneven, many inferior wire spools are copper-clad aluminum, seemingly copper wire, in fact, aluminum alloy, this line can only be used temporarily, can not be used in regular products. There are also copper wire, insulation layer, wire diameter (generally required to be equipped with 1.2 times the maximum power of the display), as long as one of these links is wrong, it may bury a safety hazard;
Second, the power supply: use inferior power supply, or the power is too small, long-term power supply overload operation;
Third, the PCB board: the material is inferior, the copper is thin, the design is unreasonable, the process is poor, the copper wire has burrs and other phenomena will cause circuit short circuit, which becomes the root cause of fire hazard;
Fourth, the heat dissipation system: LED display, especially the outdoor display, is working under high temperature for a long time, and the heat dissipation problem is the primary problem to be solved. If the design of the cooling air duct is unreasonable, it is easy to cause dust to accumulate on the fan main shaft, the power supply and the main board, resulting in poor heat dissipation, short circuit of the electronic components, and the fan is stuck, which may cause a fire.
V. Service and maintenance: On the one hand, the LED display supplier service is not in place, and the system does not provide the system's display function training, resulting in the customer's operation is not standardized; on the other hand, the LED display supplier to the sold LED The display does not perform regular maintenance, or the maintenance is not detailed and timely, resulting in failure to detect abnormal conditions in time.
Although there are fakes every year, but there are still holidays every year, what does this mean? It shows that the intensity of counterfeiting is not enough. This requires not only the supervision department to increase the intensity of the crackdown, but also the manufacturers to hold the bottom line of quality (pray the heart of the conscience) Is it possible?), also a healthy environment for the LED industry.
