In recent years, the LED industry has experienced significant growth, driven by supportive national policies, increased public awareness of energy efficiency and environmental protection, and continuous improvements in LED technology alongside decreasing costs. As a result, the downstream LED market has expanded rapidly.
According to research from the High-tech Research Institute's LED Research Division (GGII), the market size for China’s LED downstream applications reached 369.7 billion yuan in 2016, reflecting a year-on-year increase of 15.71%. GGII predicts that the output value of China’s LED downstream applications will reach 455.1 billion yuan in 2017, marking a 20.4% rise. Among these, LED lighting remains the largest application segment, with steady growth and strong demand.
As the LED lighting market recovers, demand for LED chips continues to rise. With the expansion of the small-pitch market and growing lighting demand, the LED chip industry is expected to see sustained and rapid development. GGII forecasts that the output value of China’s LED chip industry will hit 18.8 billion yuan in 2017, up 29.6% year-on-year, and exceed 28.8 billion yuan by 2020.
However, as price competition intensifies in the general lighting market, manufacturers are increasingly focusing on high-margin products such as high-power modules. Infrared LEDs have emerged as one of the most promising areas. Following the saturation of blue LEDs, infrared LEDs are gaining traction due to new applications like biometric sensing, especially with the integration of 3D sensing in devices like the Samsung Galaxy S8 and future iPhones.
The infrared LED market is expanding rapidly, with applications ranging from security monitoring and facial/iris recognition to virtual reality (VR) and automotive systems. Despite some price declines due to increased Chinese manufacturing, the demand for infrared LEDs continues to grow. The market size was estimated at around $441 million in 2017, with projections reaching $699 million by 2021.
In addition to traditional applications, emerging fields such as heartbeat and oxygen sensing, AR, and driver assistance systems are creating new opportunities. In the automotive sector, infrared LEDs and VCSELs are being used for advanced safety technologies, including driver monitoring and automated driving assistance systems (ADAS).
Taiwanese companies have long been established in the infrared LED space, with firms like Jingdian, Lite-On, Yiguang, and Ronda actively developing high-power infrared solutions. These companies are capitalizing on rising demand from mobile phones, security systems, and automotive applications.
Meanwhile, mainland Chinese companies are catching up, with firms like Guoxing Optoelectronics, Hongli Zhihui, Sanan Optoelectronics, and others making significant strides in infrared LED technology. These companies are not only improving product performance but also expanding into new markets, such as consumer electronics and automotive sectors.
With increasing competition and innovation, both Taiwanese and mainland companies are positioning themselves for long-term success in the infrared LED market. While the landscape is evolving rapidly, the potential for growth remains strong, and the race between these two regions is set to continue.
