LED market bottoming out: sales can't run the cost

As the sales of LED cannot keep up with the change of cost, the market in this area has been greatly constrained, which has caused a heavy blow to the market in this area. this is the big bottleneck that the LED industry is currently experiencing. Therefore, the discussion on improving the cost of LED has not stopped. For the improvement of LED cost, some experts have recently put forward a new industrial thinking to improve LED cost and manufacturing process. LED is recognized as green lighting in. with the characteristics of high energy saving, long service life, many changes, environmental protection and high-tech, LED general lighting has become a hot spot with market potential. If 1/3 of the current incandescent lamps are replaced by LED lamps, it will save 100 billion kWh of electricity for the country every year, which is equivalent to the one-year power generation of the Three Gorges project. At present, in the LED manufacturing process, sapphire substrate is challenged by Si and GaN substrates, but considering the cost and yield, Sapphire still has advantages in the past two years. it can be predicted that the development direction of sapphire substrate will be large size and patterning (PSS). Because the hardness of sapphire is second only to diamond, it is very difficult to thinken and flatten it. In the gradual exploration, the industry has formed a set of roughly the same process for thinning and planing sapphire substrates. Due to cost and Electrical considerations, many large manufacturers have begun to try to use non-sapphire substrate technology to create LED. Well-known manufacturers include TSMC solid-state lighting (TSMCSSL) , And Bridgelux in the United States and Toshiba in Japan (Toshiba)The combination of. In recent years, some economically developed countries in the world have launched a fierce technical competition around the development of LED. The United States has invested 0. 5 billion US dollars to implement the national semiconductor lighting plan since 2000. The Interim Measures for the administration of financial subsidy funds for the promotion of high-efficiency lighting products, which was implemented by the Ministry of Finance of China in 2008, includes semiconductor LED lighting. At present, manufacturers that use non-sapphire substrate technology to create LED are famous, including TSMC solid-state lighting (TSMCSSL) , And Bridgelux in the United States and Toshiba in Japan (Toshiba)The combination of. And this time LEDforum, Veeco, a major equipment manufacturer in the United States, told Gan-on- The progress of Si is expected to be the new focus of the future market. In addition to talking about Gan-on- Si has also introduced MOCVD equipment and higher temperature process to build power supply devices. Some manufacturers have already purchased and entered the power supply market. Japanese equipment manufacturer Dayang acid also launched Gan-on- Si's MOCVD equipment products and emphasis on niche markets. The top ten manufacturers in the market share of LED lighting revenue have already included the market share of 31, while thousands of manufacturers share the remaining 70 LED lighting markets. Since 2012, LED commercial lighting suppliers have increased gradually, leading to a significant drop in prices. In addition, the area and quantity of commercial buildings, including office buildings, shops, warehouses and hotels, have grown in 2012. at the same time, it also increases the market demand for LED commercial lighting. On the other hand, the lighting design alliance has set specifications and requirements for 4 feet lamps to cope with the rise of LED commercial lighting market. The United States has the opportunity to replace Japan as the next major LED lighting market.
