LED lighting instead of traditional fluorescent and incandescent lighting will repeat the LED-to-fluorescent (CCFL) replacement process in the field of TV backlights. It can be found that LEDs have the fastest decline in price difference relative to CCFL backlights. Permeability has a rapid rise in time.
As commercial and industrial companies are more sensitive to the cost of electricity, and government-to-business LED lighting replaces traditional fluorescent and incandescent lighting, it will repeat the LED-to-fluorescent (CCFL) replacement process in the field of TV backlights. The fastest decline in the price difference between CCFL backlights is the rapid rise of LED backlight penetration. Commercial and industrial sectors are more active in the use of energy-efficient lighting products because of the sensitivity of commercial and industrial enterprises to the cost of electricity and the stricter requirements of the government for energy conservation and emission reduction.
In the process of rapid decline in the price difference between LED lighting products and traditional lighting products, LED lighting penetration rate will rise rapidly. In the LED industry, there is a Haitz law proposed by Agilent Roland Haitz, which is considered to be the Moore's Law of the LED industry.
Since the commercialization of LEDs, the cost per lumen ($/lm) has dropped by about 20 per year, and from the data of recent years, the brightness increase and cost reduction have accelerated. According to the US Department of Energy's forecast, the lumen cost of white LED packaging will drop from 25$/klm in 2009 to 2$/klm in 2015, and the average annual cost will fall by more than 30, while the average annual decline will be between 2010 and 2012. Close to 40. The industry believes that 2011-2012 will be the fastest time difference between the price difference between LED and traditional lighting, LED lighting penetration will have a leapfrog growth during this period.
According to estimates, in terms of $/lm, the cost of LED lighting will be reduced to twice that of fluorescent lamps around 2012. If the LED is about 2.5 times longer than the fluorescent lamp, it will be around 2012. The total cost of LED lighting is ahead of fluorescent lighting. Therefore, the large-scale replacement of LED lighting will be launched in late 2011 and early 2012, and 2011-2012 will be an important investment point for the LED lighting industry.
This process will also be repeated in the replacement of LED light sources. The replacement of LED lighting products first occurs in commercial and industrial fields, and after good demonstration, it is gradually popularized into the field of household lighting. At present, traditional lighting includes fluorescent lamps, incandescent lamps, halogen lamps, HID, which account for 36, 23, 16, and 13 of general lighting revenue. With the ban of incandescent lamps in various countries, the replacement of fluorescent lamps with incandescent lamps, LED The replacement of the lamp for incandescent and fluorescent lamps will be synchronized.
