At present, although LED lighting accounts for a small amount of output in the overall lighting market and is expected to be 3.2% in 2010, LED lighting has become one of the major development policies in many countries under the global awareness of environmental protection. Help LED lighting output increase.
According to the development schedule of LED luminous efficiency defined by the United States Department of Energy (DOE), the target is set at 140lm/W in 2010 and 243lm/W in 2020. The manufacturers estimate that the annual luminous efficiency will increase by 15 to 20%. The 243 lm/W target set by the DOE in 2020 has a great opportunity to move forward.
In the case of Japan, where the recent rapid development of LED lighting is a case in point, the common ground with the US DOE is that the goal set for 2015 is to achieve a LED luminous efficiency of 200lm/W; the difference lies in the fact that Japan's NEDO has established an LED lighting terminal market. The introduction of time courses, such as the 2020 target for the sale of lighting products on the market, 100% will use high-efficiency solid-state lighting.
Lin Fenhui explained that in the LED lighting projects promoted by various countries, LED light bulbs will be one of the products that will be introduced preferentially. If the technology is not considered, the total global light bulb appetite will be about 20 billion. It is worth noting that CFL bulbs still have many advantages. Although the penetration rate of LED bulbs was only about 3% in 2011, it will reach 600 million in absolute terms; in 2013, the 40W and 60W conventional bulbs will be phased out. It is estimated that the LED bulb market can reach 2.5 billion.
If we look at the development of the overall LED lighting market, in the past LED lighting applications were mainly portable lighting, decorative lighting, and indirect lighting. From 2011 to 2011, in response to the prohibition of the sale of incandescent light bulbs in 2012, LED bulb shipments will grow significantly, with an estimated production value of approximately US$8 billion, plus countries such as North America, Japan and South Korea for LED lighting. Other green product implementation subsidy policies, and stores, shops and workshops, etc. have a higher willingness to replace LED lighting and other factors driven by the output value of the global LED lighting market penetration has a great chance of breaking 10%.
After 2012, major LED manufacturers such as Philips, Osram, and Cree will attack the general lighting market, and many countries will start budgeting and replacing LED street lights. In addition, LED lighting prices will drop by more than 30% annually. , It is estimated that the penetration rate of global LED lighting output in 2013 will further increase to nearly 20%.
