LED packaging market continues to grow and will reach 16 billion U.S. dollars in 2018

The general lighting became the largest applications of LED packaging in 2012, the growth trend of LED technologies will continue to 2018. In addition to lighting, the other LED application market is also developing rapidly.

Packaged LED market

LED packaging market will reach $ 16 billion in 2018

The packaged LED market is $ 13.9 billion now, the growth rate slow in the next five years and will peak in 2018 – $ 16 billion. At the same time, the share of lighting applications will continue to grow – from 45% to 65%. Nevertheless, the displays still share a pretty large market of the overall market. At present, LED technology is used for many products, the growth of OLED market will enable that the market is facing price pressure, and the share began to decline from 2013/2014. Price declines in the general lighting increases the market demand, the difference is that the display field is due to overcapacity in the resulting in lower prices and market downturn.

Continued growth of the LED market will reach $ 16 billion by 2018

There are three main factors that will determine the deepening development of industry and market: the costs must be further reduced so that the market further develop; the consolidation of LED industry and the lighting industry has just begun; new substrate technology may change the game rules of the industry. Despite the Sapphire and silicon carbide still is the main substrate epitaxial growth of GaN, but many research institutions are working to develop better technologies. For example, silicon nitride can make the LED production turn to 8-inch wafers,which can be processed on cheap and highly automated CMOS and ultimately significantly reduce costs. However, before that, many problems also need to be overcome. As far as the silicon GaN LED is concerned, the production yield is still too low, but can not achieve full compatibility with CMOS processing. The obstacles that silicon GaN is similar to substrate homogeneity (GaN-on-GaN) is: this technology is still facing with the problem of high costs and lack of gallium nitride substrate supply.

America “Consumer Reports”agency released the report about the best value of the LED bulbs

United States, “Consumer Reports”  institutions jointly the “7 On Your Side” column cooperation recently published the best value report on the LED bulbs. The common 60-watt and 40-watt incandescent bulbs will be discontinued on January 2014, “Consumer Reports” reported that the public does not have to rush to buy a lot for storage use, because a variety of new energy-saving lamp may be better selection.

USA ConsumerReports

America “Consumer Reports” agency released best value report on the LED bulbs

Most American families need about 50 light bulbs for home lighting. “Consumer Reports”, said the specifications of each common incandescent bulbs consume $ 8 electricity per year, or energy-saving bulbs and LED bulbs consume only $ 1.75 annually. Currently, the price of the energy-saving bulbs does not exceed $ 3 in the U.S. market,, while the LED light is of high prices, which is about $ 20-30 . However, due to the performance of energy saving and long life of the LED bulbs, the total savings of each LED bulb is about $ 125 electricity and bulb replacement costs during the life.

“Consumer Reports” thought that the advantages of the LED bulbs compared with energy saving light bulbs is that the life of the LED bulb is 2 times more than the energy-saving light bulbs; the energy-saving light bulbs usually takes 30 seconds or longer to reach full brightness, while the LED bulbs can be instantly achieve full brightness; many LED bulbs can adjust the brightness of all, which most of the energy-saving lamps are unable to achieve .

“Consumer Reports” tested a total of 750 energy-saving lights and LED bulbs, including the warm-up time, light distribution and service life. Testers using a sphere model to measure the brightness and color temperature of the bulbs, nearly all of the respects of the LED bulbs is superior to energy saving lights.

Nowadays,the LED tube light and LED bulb are the most widely used as the representatives of the decorative lighting  and the home lighting in daily life,they are enjoying a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere,meanwhile,there a large number of factory engaging in developing and producing the LED light,Lead Lighting is just one of them,which adopts high brightness SMD as the light source of the LED tube and LED bulbs so that fully guaranteed stable and soft light of the LED tube light and LED bulbs, while  low voltage constant current driver ensure the AC can be converted into the DC to improve energy efficiency of the LED tube light and LED bulbs and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is Known as energy-saving and environmental protection. Login http://www.lead-lighting.com  to know more awesome LED tube and other LED lighting.
