LED lights in the use of indoor lighting will be broader In the next few years
In the next few years LED lights in the use of indoor lighting will be broader. LED by lighting the performance of the world considered fourth-generation illuminant ideal choice, LED light source in the luminous efficiency, service life, power saving quantity is superior to traditional incandescent lamp, fluorescent lamp etc light sources. Leds luminous efficiency increased year by year, has reached general lighting applications needs.
LED lamp its superior performance is now widely regarded as an ideal choice for the first generations light source the light source, LED the luminous efficiency, service life, response time, environmental protection is superior to traditional incandescent lamp, fluorescent light sources. Leds luminous efficiency increased year by year, has reached general lighting applications needs.
LED lighting laboratory ECCO energy-saving lamps in white LED the luminous efficiency reached 200lm/w, commercial chip reach 160lm/w, and plan in 2013 200lm/w mass-production of LED lighting encapsulated by LED. 160lm module of the efficacy, remember/w for light to pass from the process of lamps and lanterns of about 50%, lamps and lanterns loss 80lm output efficiency can reach more than now, still/w 60-80lm/w fluorescent light of lights, and far more than incandescent lamp 10-15lm/w efficiency.
From efficacy, LED lighting has reached the standard to replace the traditional light source. At present the product has been reflected in a commercial applications in LED lights advantage, such as LED light bulb adopts screw base design, can be directly used to replace conventional incandescent bulbs, do not need to change the existing lamp holder and line, according to the bayonet socket size and light bulb sizes E17 type, E26 and divided the 4W LED light bulb replacement of 25W 6W incandescent bulbs, LED light bulb replacement of incandescent bulbs, 10W 40 w LED light bulb replacement 60W incandescent light bulb.
Technically, the LED lights have reached the requirements to replace the traditional light source, currently restrict the rapid spread of LED lighting is mainly caused by its high cost. LED lighting development in the future, the main direction should not be the lm/w as a representative of technology upgrades, but $/ lm, as a representative of the lower cost.
In addition to technical and cost outside, different countries and areas of energy conservation and emission reduction of government, the positive attitude to incandescent lamp products plan, production and disable the LED lighting alternative happened push important influence factors. Many developed countries planning in 2012 or so stop manufacturing and forbids the use of incandescent bulbs, LED with its energy conservation, emissions reduction and environmental protection etc advantages, it is the ideal choice incandescent lamp replacement, once the technology and cost proper, is expected to get governments in policy support.
Through the analysis of the TV back light field has LED to fluorescent lamps (CCFL) process of replacement can be found LED backlight relative CCFL price difference, the period of the fastest decline LED backlighting permeability is rising fast time appear. LED lighting replace traditional fluorescent lamps and incandescent lighting will repeat this process.
In LED lighting products and traditional lighting products price difference of rapid decline process, LED lighting permeability will rapidly rising. There is a LED industry in RolandHaitz proposed by agilent Haitz law, is considered to be LED industry Moore's law. Since every lumens LED commercialization, cost ($/ lm), and about 20 percent annual decline from recent data to see, the brightness of ascension and cost reduction have accelerated trend.
According to the U.S. department of energy's prediction, a white LED encapsulates the lumen cost will from 2009 25 $/ KLM, descend to 2015 2 $/ KLM, the cost of the average annual drop in 30% above, and by 2010-2012 years. We covered nearly 40% annual that 2011-2012 will be LED and traditional lighting spreads fastest period, the decline in the LED lighting permeability will produced during rapid growth. According to our estimates, to $/ lm for measurement unit, in 2012 or so LED lighting cost will drop to twice the fluorescent, such as relative fluorescent about 2.5 times LED the life count in 2012, will make the assembly abilities LED lighting around before fluorescent lighting.
