As a rare earth luminescent material, LED phosphor industry has good development prospects

广告位

LED phosphors, also known as light-emitting diode phosphors, are rare earth luminescent materials and are widely used in the field of white light emission. Since the luminous efficiency of LEDs in different bands varies greatly, after using LED phosphors, the advantages of high luminous efficiency of LEDs in some bands can be used to improve the luminous efficiency of LEDs in other bands. Compared with multi-chip white LEDs, LED phosphors have the advantages of fast heat dissipation and low production costs, and play a decisive role in improving the color rendering and light quality of LED products.

According to different raw materials, LED phosphors are mainly divided into sulfide phosphors, silicate phosphors, phosphate phosphors, oxide phosphors, molybdate phosphors, aluminate phosphors, etc. Aluminate phosphor is one of the most mature LED phosphors currently produced and applied. It has the advantages of low production cost, high luminous efficiency, and stable chemical properties. However, it is prone to low color rendering and high color temperature in applications. Silicate phosphor is a kind of phosphor with various structures made of strontium carbonate, silica, and barium carbonate as raw materials. Its emission wavelength can reach 610.0nm and its excitation band is wide. It is the main material for making white light LEDs.

According to the “2022-2027 China LED Phosphor Industry Market Supply and Demand Status and Development Trend Forecast Report released by the Industrial Research Center, LED lighting is the end market for LED phosphors. For a long time, incandescent lamps have dominated my country’s lighting market, but they have shortcomings such as high power consumption, short service life, and low optical efficiency. As concepts such as energy conservation continue to deepen, the demand for LED lighting products in my country has increased significantly. In 2021, my country’s LED lighting market will reach 964.78 billion yuan, a year-on-year increase of 11.2%. At present, the market penetration rate of LED lighting products in my country has exceeded 85.0%. Driven by the rapid development of downstream industries, my country’s LED phosphor output continues to increase. According to statistics from the Department of Raw Materials Industry of the Ministry of Industry and Information Technology, my country’s LED phosphor output reached 698.0 tons in 2021, a year-on-year increase of 59.0%.

In terms of market competition, global LED phosphor manufacturers are mainly concentrated in the United States and Japan, including Intematix of the United States, Neka Chemical of Japan, Tokuyama of Japan, etc. Driven by market demand, the prosperity of my country’s LED phosphor industry continues to improve, attracting many companies to enter the industry. However, due to factors such as high production technical barriers, the quality of my country’s LED phosphor products is uneven and unable to meet high-end market demand. At present, my country’s LED phosphor market is still dominated by small and medium-sized enterprises, including Jiangsu Borui Optoelectronics, Shenzhen Dalihao Electronics, Dongguan Kaiyong Optoelectronics, etc.

As an essential material for manufacturing white LEDs, LED phosphors are in high demand in the global market. The global LED phosphor market size will reach US$1.86 billion in 2021, a year-on-year increase of 9.6%. Industry analysts said that with the deepening of concepts such as green environmental protection and energy conservation, the LED phosphor market The scale is expected to be further expanded. Overall, LED phosphors, as important rare earth luminescent materials, will continue to have good industry development prospects.
