By the weak global economy and production overcapacity, the development of the LED lighting market is not as previously expected rapid, coupled with immaturity on lighting terminal markets, the majority of consumers are price-oriented, making the development of LED lighting market increasingly slowdown.The revenues of Edison Opto (3591) in the third quarter are $ 5.64 billion New Taiwan dollars, compared with NT 676 million yuan of revenue in the second quarter fell by 12.33%, Edison also will hold conservative attitude for the fourth quarter ,it is expected that at the fourth quarter it is still hard to get rid of the market predicament, revenue will be flat with the third quarter , the industry supply and demand imbalances may also affect the first half of next year. LED lighting industry got great attention this year, LED enterprises and countries are vigorously inputs, corresponding to the market, however,it did not get the high-speed development, resulting in capacity increases faster than the speed of market growth; in addition, the slow growth of the global economy had a huge impact on the LED industry which caused orders from the market were less than expected; strongly, price competition is becoming increasingly fierce in the LED industry, which bad affects development of LED manufacturers. Edison Opto's conservative estimate for the fourth quarter is also a prudent move.  Lighting weak demand and overcapacity are not only the issues of Edison Opto , but also the problems faced by the LED lighting industry, we need to concern. Now the problem has been very obvious, LED lighting market need to continue to vigorously develop, enterprises should also have a goal to design and production. Only do the work of both production and demand, and to vigorously promote the popularity of LED lighting, to promote the development of green lighting.
