The cost of LED lighting industry and policy-driven investment point asymptotic

Philips Lighting expects the current worldwide chevrolet cruze dvd size of 630-700 billion dollars in 2010-2020 will average 6% growth rate. Value in the general lighting, lighting fixtures and lighting applications account for about 70% of the share of light bulbs account for about 20%. This replacement bulb from some of the major needs, some of the light bulb as a light source has been calculated in lamps and lighting applications.
According to LEDinside statistics, in 2009, LED lighting, global lighting market value of about $ 2.4 billion, only 3.3% penetration rate. Philips LED lighting is expected in the general lighting market worldwide by 2015 the proportion will rise to 50%, 80% in 2020.
market drivers: from technology to costs
LED industry for its excellent cheap full lace wig is generally considered ideal for the fourth-generation light source, LED light source In the luminous efficiency, lifetime, response time, and environmental protection are better than incandescent, fluorescent and other traditional sources.
LED luminous efficiency has increased annually, has reached the general lighting applications. From Cree 2010, the latest published results, at present its white LED luminous efficiency of the laboratory 200lm / w, commercial chips to 160lm / w, and plans to mass production in 2013 200lm / w of the LED. LED lighting package module light efficiency of 160lm / w mind, from light to light through the process of loss of about 50% of the lamp light output efficiency to 80lm / w, still more than the current fluorescent 60-80lm / w luminous efficiency, and far more than incandescent 10-15lm / w efficiency. Effect from the light on, LED lighting to replace traditional light sources has reached the standard.
currently commercialized products has been reflected in the luminous efficiency of LED's  Cooling tower , such as the use of screw-type base LED bulb design, can be used to replace traditional incandescent bulbs, do not change the existing lamp and line, according to the mount dimensions and size classification E26 and E17 bulb type, 4W LED bulbs can replace 25W incandescent bulbs, 6W LED bulbs can replace incandescent bulbs 40W, 10W to 60W LED bulbs can replace incandescent bulbs.
technology, LED light efficiency has been achieved the requirements of an alternative to traditional light sources, LED lighting is currently restricting the rapid spread of the main factors is its high cost. Future, the main direction of development of LED lighting, should not be lm / w, represented by the technology upgrade, but $ / lm represented costs.
In addition to technology and  laptop bag , national and regional governments on energy conservation a positive attitude, discontinued products for incandescent and disabled program is to promote LED lighting alternative place an important factor. Planning in many developed countries around 2012, to stop manufacturing and prohibit the use of incandescent bulbs, LED energy saving and environmental protection with its advantages, is the ideal alternative to incandescent LED fluorescent tube , once the appropriate technology and cost, is expected to be the policy of Governments on the support.
