Breakthroughs in UV LEDs have accelerated the pace of replacing conventional lamps used in research and industry, and UV LEDs have been able to take full advantage of their performance in different spectra. UV-A lamps (wavelengths 315-400 nm) are commonly used for curing applications, while UV-B and UV-C LEDs (280-315 nm and 100-280 nm, respectively) have the potential for medical applications and purification/disinfection. These advances are attributed to the development of materials research and development and improvement of manufacturing processes. The following introduces the latest UV LED device applications and recent results.
UV LEDs slowly warm up in the quiet corner of the LED market
Compared to visible light LEDs, UV LED is a quiet market, only about 30 million US dollars, but recently, with the breakthrough of radiation power, strength has been applied to replace mercury vapor lamps used in UV drying and counterfeiting detection.
UV-LED Advances Longer Curing Life
In 2013, we witnessed the more efficient application of LEDs for faster curing in UV curing applications, including applications in various types of life sciences and industrial applications, and optimizing the lifetime of components.
LED plays an increasingly important role in the application of life sciences
LED lighting technology can improve our health, serve rehabilitation, diagnose and identify life-threatening conditions.
UV LEDs extend the shelf life of fresh produce
SETi (Sensor Electronics Technology Co., Ltd.) and USDA (US Department of Agriculture) both stated that UV LEDs extended the shelf life of fresh produce, and Sensor Electronic Technology reported that under the guidance of the US Department of Agriculture, according to a study on strawberries, The UVB spectrum with LEDs can double the shelf life of refrigerated products.
