Infrared LED Market: Snapshot
Infrared (IR) LEDs are the transmitters which radiate IR beams at a more drawn out wavelength than obvious light. These gadgets are comprised of aluminum arsenide or aluminum gallium arsenide and have a working voltage of around 1.4V. The IR LED emanates wavelength at the scope of 760 nm and is hence undetectable to the human eye. Expanding installation of 6-inch sapphire wafer substrate is picking up noticeable quality as the 6-inch wafer lessens the expense of LEDs when contrasted with 2-inch wafers. The 6-inch wafers makes the creation more effective as there is no space squandered and edge misfortunes are lessened. The expanding establishment of closed circuit TV cameras for observation will propel the development prospects for the worldwide infrared LED market for the following few years.
CCTV cameras are incorporated with infrared LEDs as a key segment that gives night vision and provides with low-light level applications. Likewise, the mechanically propelled current IR LEDs offer propelled picture improvement and are more solid and enduring. Besides, the mix of CCTV cameras along with infrared LED provides expanded optical yield, extensive variety of discharge edge, and close field perceivability applications.
The relocation of LED producers to 6 inch sapphire wafer substrates will support the development possibilities for the worldwide infrared LED market before the finish of forecast period. As the 6 inch wafers influence the creation to process more productive and diminish the expense of LEDs not at all like on account of 2 inch wafers that outcomes in more squandered space and edge misfortune, the makers are progressively relocating towards 6 inch sapphire substrates. The worldwide infrared LED market is exceedingly aggressive due to the awareness of countless and global merchants over the globe. It has been watched that numerous enormous players are encountering a decrease in their market share as a result of the expanding number of Chinese makers.

Infrared (IR) LEDs are the transmitters which emit IR rays at a longer wavelength than visible light. These devices are made up of aluminum arsenide or aluminum gallium arsenide and have an operating voltage of around 1.4V. The IR LED emits wavelength at the range of 760 nm and is thus invisible to the human eye. Increasing adoption of 6-inch sapphire wafer substrate is gaining prominence as the 6-inch wafer reduces the cost of LEDs when compared to 2-inch wafers. The 6-inch wafers makes the production more efficient as there is no space wasted and edge losses are reduced.
Growing demand of infrared LEDs for integration of hyper spectral imaging and remote sensing in consumer electronics, automotive, and other allied industries is expected to drive the industry over the forecast timeline. Increasing popularity of these devices amongst end-users DIY (do-it-yourself) security cameras is anticipated to support the industry demand. Rising security concerns and ever expanding smartphone industry are fulfilling the demand of infrared LEDs globally. Increasing construction of smart homes and commercial complexes will demand for more secure equipment for the security purposes in the coming years. Technological advancements in infrared LEDs in defense, imaging, lighting, automotive, and consumer electronics is expected to fuel the global infrared LED demand from 2017 to 2025.
Low power consumption, high security and low cost benefits is projected to support the infrared LED industry as these devices are used in combination with receivers for use in varied products such as wireless mouse, remote controls, and telecommunication modules. Manufacturers are focusing on implementation of infrared LEDs in various multimedia devices such as mobile phones & tablets and surveillance systems. Emerging technologies in closed circuit televisions (CCTVs) and smartphones such as iris and facial recognition is anticipated to be a quickly growing trend in the industry. For instance, Samsung’s smartphone Galaxy S8 features iris and facial recognition to meet and secure the growing demand of mobile payment services. The widespread promotion of mobile payment services on devices such as notebooks and smartphones featuring user authentication based on infrared LED technology, is predicted to be the primary growth driver of the industry over the forecast timeline.
IR LEDs are integrated into CCTV cameras as primary component as it offers low-light level and night vision applications. The technological advancements in modern infrared LEDs offer advanced image enhancement which are more reliable and long lasting. The integration of IR LED with CCTV cameras offers wide range of emission angle, increased optical output and near-field visibility applications.
The automotive industry is witnessing rapid innovation in the field of infotainment, safety systems, telematics, advanced driver assistance systems (ADAS) and autonomous driving. These technologies actively involve the integration of IR LEDs for their operation. Furthermore, infrared systems are integrated into automobiles to improve the blind spot and night vision driving, thereby supporting the global infrared LED market growth in the automobile segment.
The infrared LED industry is highly diversified and competitive owing to the presence of large number of regional and international vendors globally. Some of the major factors driving the industry growth in Asia Pacific region is the presence of large number of LED manufacturers in countries such as Japan, China and Taiwan. Prominent industry participants are Epistar, Osram, Everlight, Vishay, Nichia and Philips. The companies are primarily focusing on new product development in order to retain their market share.
For instance, in June 2017, Osram launched the smallest side-looking infrared LED which has wavelength of 850 nm which is used for eye tracking applications in virtual reality (VR) and augmented reality (AR) headsets. Both AR and VR systems react to the eye and head movement making the infrared LED as the critical component of the headset designs.
