Development of Deep Ultraviolet LED Packaging

Abstract

Deep UV LED package is a hotspot of growing concern for research scholars, it is through the LED semiconductor light-emitting devices emit UVC band ultraviolet (typical wavelength 260 ~ 280nm), is a new type of healthy artificial light source, compared with the traditional UV light source mercury lamps, the deep UV LED has a wavelength of accurate and controllable, green, and so on many advantages. Due to the high-energy deep UV radiation capability, it has a strong bactericidal and inactivation effect on bacteria, viruses and other microorganisms. In recent years, with the continuous progress of deep packaging technology, the optical efficiency and reliability of deep UV LEDs have been significantly improved. This paper summarizes the key technologies of deep-ultraviolet packaging, the performance of deep-ultraviolet LEDs and the application of deep-ultraviolet LEDs; through the understanding of the packaging materials, packaging structure, packaging process and so on to improve the performance of deep-ultraviolet LEDs, so that it is better to apply to the market, which can be seen that the deep-ultraviolet LEDs have a great prospect for development.
