The future market development prospect of high-power LED
High-power LED refers to a light-emitting diode with a large rated operating current. Usually LED power is usually 0.05W, operating current is 20mA, while high-power LEDs can reach 1W, 2W, or even tens of watts, and the operating current can range from tens of milliamps to hundreds of milliamps. As the fourth-generation electric light source, high-power LED has excellent characteristics such as small size, safe and low voltage, long life, high electro-optical conversion efficiency, fast response speed, energy saving, and environmental protection.
In recent years, the high-power LED market has developed rapidly. The scale of the global high-power LED market has increased from US$5,053 million (approximately RMB 33.514 billion) in 2008 to US$12,399 million (approximately RMB 82.235 billion) in 2015. It is estimated that the size of the global high-power LED market in 2016 will reach about 85 billion yuan. High-power LEDs have developed rapidly in the early stage, and are expected to gain large-scale growth in some special lighting fields in the future. The medium and long-term goals include gaining a larger share in the field of general lighting, and the development prospects are outstanding.
In the LED market, high-power LEDs have a good prospect. They can not only be used in the traditional outdoor lighting market and the flashlight market, but also gradually penetrate into new fields such as car headlights, mobile phone flashes, and ultraviolet LED lights. The global high-power LED market scale is increasing year by year, and ceramic packaging has irreplaceable advantages compared to PPA/PCT packaging and EMC packaging. Ceramic substrates have become a necessity for high-power LEDs.
High-power LEDs have multiple advantages over traditional lighting. Longer service life, high-power LED street lamps have a service life of more than 50,000 hours; more energy-saving, saving more than 80% of electricity compared to high-pressure sodium lamps; more green and environmentally friendly, high-power LED street lamps do not contain lead, mercury and other polluting elements, no harm to the environment No pollution; it is safer to use, has strong impact resistance and strong shock resistance, the light emitted by the LED is in the visible light range, without ultraviolet and infrared radiation, and there is no filament and glass shell, and there is no doubt about the fragmentation of traditional lamps. LED street lights can replace the use of traditional lighting, because it is compatible with products, interchangeable, and modular, standardized and standardized in functional lighting applications. The light decay of high-power LED street lights is small, and the light decay in one year is less than 5%. After 10 years of use, the illuminance requirements of road applications can still be reached. However, the light decay of traditional lighting is large, and it has dropped by more than 30% in one year.
Market, technology and capital complement each other and influence each other. Technological progress has given birth to new application markets, while cost reduction has promoted the infiltration of technology into new-type markets. The rise of new-type markets has put forward higher requirements for technology and cost. This dependence is no exception to the LED industry. Since 2013, in addition to the traditional outdoor lighting market and the flashlight market, high-power ceramic packaged light sources have gradually penetrated into the fields of car headlights, mobile phone flashes, and ultraviolet LED lights.
The total amount of China's LED packaging market is infinite. In 2008, the scale of China's LED packaging market was about 18.5 billion yuan. By 2015, the scale of China's LED packaging market has grown to 61.5 billion yuan, and will continue to increase. Especially in recent years, the ceramic packaging market has developed rapidly, reaching an annual growth rate of 10 billion yuan in 2014 and 2015.
It is estimated that in the next few years, LED street lamps, car lighting, landscape lighting and other fields used by high-power LEDs will usher in a new round of development, which will surely further increase the market share of high-power LEDs, and the market prospects are promising.
