LED long-term development requires quality assurance

LED long-term development requires quality assurance The rapid development of LED lighting has also brought opportunities for the development of the LED lighting market. At the same time, consumers’ increased awareness of energy conservation and environmental protection has also prompted more and more users to turn their attention to LED lighting, which has brought a huge area for the development of the entire industry. However, the rapid growth of LED lighting products has not been as steady as the development of the industry, but the lack of relevant regulations and consumers' understanding of the product has placed Kung Fu on reducing product quality in order to further reduce prices. To win over consumers and ignore the guarantee of product quality.

The development of low-quality, low-cost products has never been a long-term solution, especially for LED lighting products with more stringent quality requirements.

Foreign markets first strengthened the certification and supervision of lighting products. The European Commission’s Production Design Directives Regulatory Commission discussed the directional lamps and all LED lights and related equipment bills, adding new ErP directives. U.S. LED lighting TBT notifications recently began to comment on the recent US TBT report on LED lamp testing procedures, involving LED lamp lumen output, input power, and relative spectral distribution methods. The mandatory standards for LED lamps revised by the Mexican economic sector will take effect from May 5 this year.

With the continuous development of the industry and the market, the quality of China's LED lighting products began to highlight. In less than half a year's time, China's LED lighting products in the international market, "the limelight." First, Canada recalled the lighting products produced in China. Then the US Consumer Product Safety Commission voluntarily recalled the KED lamps in China, followed by the EU and issued a consumer warning on the quality of LED lamps produced in China.

Quality problems have become a major issue hindering the development of China's LED lighting industry. China's LED lighting manufacturers have relied on low prices in exchange for the market, but the development of LED still needs long-term plan. If we can't improve product quality, we will be at a disadvantage in the future development.

The advantages of LED lighting rely on the assurance of product quality. Low-quality products not only lose the market, but also adversely affect the overall development of the industry. With the development of market globalization, foreign products will also occupy the domestic market. After China's LED lighting products lose their geographical advantages, the products that are at a disadvantage in quality will also face terrible consequences.

Compared with traditional lighting products, the main advantages of LED lighting are higher light efficiency and longer life. These advantages are closely related to the quality of the products. The quality of the products is not too hard, and the advantages of LED lighting cannot be discussed.

Whether it is the domestic market or international competition, the development of LED products can not be separated from the quality assurance. Whether it is from the perspective of the development of the industry or from the perspective of the long-term perspective of the company, it is necessary to improve the quality of LED products. Only by guaranteeing the quality of their own products can companies be invincible in their development.

SCSI-90°DIP Section

Small computer system interface (SCSI) is an independent processor standard for system level interfaces between computers and intelligent devices (hard disks, floppy drives, optical drives, printers, scanners, etc.). SCSI is an intelligent universal interface standard.

The last SCSI device in the SCSI chain uses a terminator, and the intermediate device does not need a terminator. Once the terminator is used by the intermediate device, the SCSI card cannot find the future SCSI device. If the last device does not use a terminator, SCSI will not work properly. Terminator is composed of resistors, located at the end of the SCSI bus, to reduce the mutual influence of the signal, maintain the constant voltage on the SCSI chain.

Most of the SCSI devices have built-in terminators and use a jumper to control on / off. The SCSI device is highly intelligent and can automatically control the terminator on / off. For example, if a hard disk is connected to a CD-ROM, the CD-ROM can work normally regardless of whether the terminator of the hard disk is on or off. However, when two hard disks are connected, the situation becomes more complicated. Before two Seagate hard disks are connected, one hard disk terminator must be off. Before a Seagate hard disk is connected to a quantum hard disk, a hard disk terminator can work normally regardless of whether it is on or off.
