The breakthrough of UV LED has accelerated the pace of replacing traditional lamps used in scientific research and industry. UV LED has been able to make full use of their performance in different spectra. UV-A lamps (wavelength 315~400 nm) are commonly used in curing applications, while UV-B and UV-C LEDs (280~315 nm and 100~280 nm, respectively) have potential for medical applications and purification/disinfection. These advances are attributed to advances in materials research and development as well as manufacturing process improvements. The following introduces the latest UV LED equipment applications and recent results.
Compared to visible light LEDs, UV LEDs are a quiet market with only about $30 million, but recently, with breakthroughs in radiant power, the intensity has been applied to replace mercury vapor lamps used in UV drying and counterfeit detection.
The application of LED in life sciences plays an increasingly important role
LED lighting technology can improve our health, serve in rehabilitation treatment, and diagnose and identify life-threatening conditions.
UV LEDs extend the shelf life of fresh produce
Both SETi (Sensor Electronics Technology Co., Ltd.) and USDA (United States Department of Agriculture) stated that UV LEDs extend shelf life of fresh produce, Sensor Electronics reports, under guidance from the U.S. Department of Agriculture and based on a study on strawberries, LEDs in the UVB spectral band can double the shelf life of refrigerated produce.
Crystal IS announces that UV-C LEDs can be used for test and measurement applications
UV LEDs based on native AlN substrates emit peak wavelengths in the 250~280nm range and can be used in life sciences, such as water quality monitoring and chemical detection.
LED ENGIN (Silicon Valley Light Engine) announced that UV LED can be used for curing of demanding applications
Gen 2 UV LEDs can deliver 1000 mW lumen output from a 4.4 x 4.4 mm footprint and 2.8W input power.
