Uncertain start of the lighting industry growth or slowdown this year

It is understood that lighting industry is generally concerned that this year may be affected by multiple factors such as cost pressures, the impact of property market policies, and weak internal and external demand, the industry growth rate will be significantly lower than last year, the price index has continued to decline in recent years, LED lighting products may this year Faced with a more serious price war.

The prices of commercial lighting products started to decline this year. The trend of the wholesale price index of lighting products in the ancient town of Zhongshan shows that in addition to the 7.28% decrease in the commercial lighting series index in the first few weeks of this year, the LED application series index, the lighting series index, the outdoor lighting series index, and the light source series index Both rose slightly.

Some market participants said that in 2011 the lighting industry experienced a period of recession, the market generally reflects the peak season is not prosperous, the off-season is even lighter, the ancient town lighting price index out of a twisting line in the atmosphere of no prosperity, but overall, still Better than 2010, the annual lighting wholesale price index rose by 19.0%.

This person predicts that in 2012 the lighting industry will face the pressure of high raw materials, slower growth of internal and external demand, and intensified competition in the industry. In 2012, the Guzhen Lighting Price Index will continue to show the ups and downs of the traditional light season. There was a steady increase, but the increase was slightly slower than in 2011.

From the index point of view, outdoor lighting series index volatility in the most recent six months, the beginning of this year is still unstable, the first week index was 91.80, the third week fell to 81.1, currently rose to 88.4, or 5.62%, is a rise in several indicators biggest.

The light source series index rose overall in the past six months, but it fluctuates significantly in the second half of this year. The index for the second week of this year was 115.70, but it fell more than 10 points in the second and third weeks.

The cost of LED lighting is reduced, but the price war LED lighting is currently the hottest lighting lighting industry. With the fierce fighting in the past two years, LED lighting product technology continues to reduce driving costs, but it is also inevitable in the industry. Set off a fiercer price promotion campaign.

According to the reporter's understanding, under the support of government policies, LED has become the direction of transformation and upgrading of large and small lighting lighting companies. Whether it is chips, epitaxial wafers, or packaging and applications, the number of LED lighting has exploded. The LED application series index shows that although the price decline has slowed down in recent months due to the high cost of raw materials and other factors, overall, the industry as a whole has shown that prices continue to decline.

This year, LED product prices have started to rise, and business owners predict that despite intense competition, LED and energy-saving products will have a better development this year. The main reason is that the government will ban sales and import of general lighting of 100 watts and above in the near future. With incandescent lamps, policies will promote the wider application of energy-saving lamps and LED lighting.

Raw material prices and real estate policies will continue to impact the lighting industry. In 2011, it can be seen that the rise in raw material prices, labor costs, and logistics costs hampered the development of enterprises. According to the calculations of enterprises, production costs will increase by 20% to 30%. Another major pressure comes from the deepening of real estate policy control, and the weak growth in terminal demand for lighting products.

According to the company's forecast, from the perspective of the state policy and the macroeconomic operating environment, the regulation of the domestic real estate industry in 2012 will not be relaxed, which means that the relevant lighting industry in 2012 will still face greater marketing resistance.

SCSI Solder Type 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.

In addition to SCSI, IDE is also a very common interface. From the point of view of ease of use, IDE is more suitable for ordinary users. In addition, personal computer users not only need to configure a few peripherals, but also do not require high speed. Therefore, it is more appropriate to choose IDE interface. In addition, IDE also has the characteristics of high performance price ratio and wide application. Although the SCSI interface has many incomparable characteristics, the price of the interface and its peripherals is too expensive to be borne by ordinary users, which determines the limitation of its actual use range.

1. The working mode of IDE requires the whole process participation of CPU. When the CPU reads and writes data, it can't perform other operations. In this case, in the multitask operating system of Windows 95 / NT, the system reaction will be greatly slowed down. The SCSI interface controls the data reading and writing operation completely through the independent high-speed SCSI card, so the CPU does not have to waste time to wait, which obviously can improve the overall performance of the system. However, IDE interface has also made great improvements to improve this problem. DMA mode can be used instead of PIO mode to read and write data. DMA channel is responsible for data exchange, which greatly reduces the CPU consumption. However, comparing the CPU utilization of SCSI and IDE, we can find that SCSI still has considerable advantages.

2. The scalability of SCSI is larger than that of IDE. Generally, each ide system can have two IDE channels, with a total of four IDE devices. The SCSI interface can connect 7-15 devices, much more than IDE, and the cable connected is far longer than ide.

3. Although the price of SCSI device is higher, compared with IDE, the performance of SCSI is more stable, durable and reliable.
