Seoul Semiconductor is the biggest manufacturer of eco-friendly LED lighting technology in Korea and is one of the top eight manufacturers in the world. The products have been widely used in general lighting, display lighting, cell phone back-lighting, TVs, laptops, automotive lighting, household products and traffic signals. Known for its LEDs’ performance, efficiency and reliability, Broadcom offers an extensive portfolio of products that include high brightness and high power LEDs, PLCC surface-mount LEDs, and display backlighting module solutions. These LEDs and display modules address a wide range of markets, including electronic signs and signals, automotive, solid state lighting and LCD display backlighting. As a result of their advantages over conventional adhesive systems, the use of UV-curable adhesives in the packaging industry in the region’s countries is growing at a phenomenal rate.

How LEDs are Made

The coronavirus pandemic had a positive impact on the industry due to surging number of COVID-19 cases. As UV LED aids in disinfection and sterilization, many countries accepted this technology to curb the spread of the illness. Consequently, increasing awareness regarding the benefits of these devices, particularly for air, water, and surface purification, has elevated product uptake. Japanese and Korean manufacturers are market leaders, followed by a growing Western interest in building high-power, UV-C LEDs to meet the needs of the water treatment industry. During the forecast period, the UV-C LED market is anticipated to split into a standard consumer market and an advanced commercial/industrial market. The ink market is expanding at a faster rate than the graphics and packaging market as a whole.

The company demonstrates this by maintaining control over materials, processes and technologies and by helping customers engineer the best quality of light for their application to achieve the highest levels of performance. In 2013, most European nations adopted energy-saving policies and ratified the Minamata Convention on mercury. It is anticipated that this will reduce the use of LP UV lamps and open up opportunities for the UV LED market demand, driving demand in all European countries. In the region, printing, healthcare, horticulture, and consumer products are the industries with the most significant influence on the market for UV LEDs. Water disinfection and purification products account for the majority of consumer demand.

Drive revenues by understanding the key trends, innovative products and technologies, market segments, and companies likely to impact the Market in the future. In our Hubei province, China, we have our production plants, and we are able to produce independent products. The factory has been in existence for more than 20 years and has a complete production system and management system. In addition, we also have a professional R & D team to continuously optimize our company’s products, and strive to develop a variety of products that customers need and market needs. In terms of type, the UV LED market is segregated into UV-A, UV-B, and UV-C. The UV-C LED segment is anticipated to reach a valuation of over USD 700 million by 2030.

A substrate temperature in the range of 720–740 °C was used for the AlGaN epilayers; and for the AlN epilayers the substrate temperature was roughly 100 °C higher compared to AlGaN epilayers. The Mg doping concentration in the p-AlGaN layer was 1 × 1018cm−3, estimated by the secondary-ion mass spectroscopy . Schematic of the AlGaN DH LED structure grown on top of the AlN buffer layer on Si. UV LED Printing System -temperature PL spectra of the AlGaN active region and cladding layers. I–V characteristics of an AlGaN DH LED with a device size of 1 mm × 1 mm.

A 213 nm pulsed laser with a pulse width of 7 ns was used to excite the sample. The emitted light from the sample top surface was collected by an optical fiber, which was further coupled to a deep UV spectrometer. In this regard, the optical fiber was tilted at various angles with respect to the axial direction for the light detection, as illustrated in Fig.4d.

Companies manufacturing electronic devices incorporate UV LED components to produce innovative and effective products. In this work, we have demonstrated vertical AlGaN deep UV LEDs on Si. Such devices are made on a special AlN buffer layer that is formed with the assistance of a nanowire-based template. Therefore, this work enables a practical path for high performance vertical semiconductor deep UV LEDs. Deep UV light sources play a critical role in our everyday life for a wide range of applications in disinfection, UV curing in the production of any personal electronic devices, and bio-chemical sensing.
