From chip to package to terminal, interpret the development status of UVC LED
In the past two years, affected by the global economic downturn and geopolitical conflicts, the growth rate of the global LED lighting market has slowed down significantly.
As the midstream link of the LED lighting industry chain, the growth rate of LED packaging has also slowed down in the past two years. According to statistics from the LED Research Institute (GGII), the output value of LED white light packaging in China in 2020 is about 66.55 billion yuan, a year-on-year decrease of 6.3%;
In 2021, driven by factors such as the export of general lighting, the recovery of the display market, and the rapid increase in the penetration rate of Mini backlight, the overall LED industry will recover.
Data from the LED Research Institute (GGII) also shows that the output value of China's LED white light packaging will reach approximately 69.5 billion yuan in 2021, a year-on-year increase of 4.4%.
Recently, companies related to the LED industry chain have released their 2021 annual reports. Gaogong LED has compiled the performance reports of 11 LED packaging listed companies. What is the result?
According to the report, driven by the strong demand in the downstream market, the overall revenue level of the above 11 LED packaging listed companies has generally maintained steady growth, and only the revenue of Lianchuang Optoelectronics has declined.
However, although the revenue of various LED packaging manufacturers has generally maintained growth, nearly half of the companies have increased revenue without increasing profits, including Wanrun Technology, Lianchuang Optoelectronics, Jufei Optoelectronics, etc.
For the decline in net profit, the reasons given by various companies are mainly concentrated in the following aspects: provision for asset impairment, increase in operating costs, economic downturn, etc.
Due to the differences in the proportion of the main business of each company, Gaogong LED has separately summarized the LED packaging business of each company. The results show that the revenue of eight companies including Dongshan Precision, Zhaochi, Mulinsen, Nationstar Optoelectronics, Hongli Zhihui, Ruifeng Optoelectronics, Wanrun Technology, and Changfang Group have maintained steady growth. Three companies including Chuang Optoelectronics and Jufei Optoelectronics declined.
Jiangsu AMICC Optoelectronics Technology Co., Ltd. was founded in 2009 and listed on the New Third Board in 2015. It is a specialized enterprise dedicated to the production and processing of semiconductors and optoelectronic components. Amicc Optoelectronics has established ISO9001:2015 quality management system, ISO14001:2015 environmental management system, ISO45001:2018 occupational health and safety management system, IECQ QC080000:2017 hazardous substance management system and IATF16949 automotive quality management system, and passed third-party certification .Read More →
LED packaging is a technology involving multiple disciplines (such as optics, thermals, mechanics, electricity, mechanics, materials, semiconductors, etc.). (As shown in Figure 1) From a certain point of view, LED packaging is not only a manufacturing technology (Technology), but also a basic science (Science), excellent packaging engineers need to understand thermal, optical, material and process mechanics Have a deep understanding of the nature of physics.Read More →
