In the past two months, related products in the LED lighting market have ushered in a wave of price increases. In December last year, a number of domestic lighting companies have intensively issued price increase letters, and the price increase rate is mostly 10%. The agency believes that in 2021, it is optimistic that the LED industry will continue to pick up, and the concentration of lighting benefits will continue to increase; in terms of display, new infrastructure will significantly drive the reversal of LED display demand. Mulinsen is a major manufacturer in the global LED packaging industry. Leyard Company is mainly engaged in the research and development, design, production and sales of LED application products. The Lijing Microelectronics MicroLED display mass production base established by a joint venture with Taiwan Epistar has officially put into production.
From the perspective of the industry chain, the upstream of the LED lighting industry chain is the production of substrates and epitaxial wafers, the midstream industry is the production of LED chips, and the downstream is LED packaging and display, backlight applications, automotive lighting, general lighting and other applications. Among them, the production of upstream epitaxial wafers and midstream chips is the key technology of LEDs, with high technical content and large capital investment. It is also an area with the most intense international competition and the greatest business risk.
From the perspective of penetration rate, China is the largest manufacturer of LED lighting products. According to the statistics of the National Semiconductor Lighting Engineering Research and Development and Industry Alliance (CSA), the domestic market penetration rate of LED lighting products in China (the domestic sales of LED lighting products/lighting products The total domestic sales volume) increased rapidly from 3.3% in 2012 to 70% in 2018, far exceeding the global average.
