An LED that emits light in the “UV-C” wavelength region is known as a deep-UV LED (100 to 280 nm). Deep-UV LED development is becoming extremely active right now.
This is due to the huge rise in demand for Deep-UV LEDs as a substitute for mercury lamps, which have traditionally served as the primary light sources for UV light application equipment such sterilisation equipment.
Due to the step-like growth of one of their bottom layers, deep ultraviolet light-emitting diodes (DUV-LEDs) built of aluminium gallium nitride (AlGaN) efficiently convert electrical energy to optical energy.
Deep UV LEDs are frequently employed in civil industries such as biological detection, air purification, and water purification. The use of a UV light source goes well beyond simple sterilisation and disinfection.
Additionally, it has promising futures in other growing disciplines, including biochemical detection, medical sterilisation, polymer curing, and industrial photocatalysis.
The Global Deep UV LED market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
With a choice of a flat window, hemispheric lens, or ball lens, Photon Systems provides UV LEDs with centre wavelengths of 280 and 255nm. Although UV LEDs have a significantly wider linewidth and lesser brightness than lasers, they are nevertheless valuable components for creating portable equipment that are less expensive.
The LEDs are useful for fluorescence-based detection but unsuitable for Raman due to their 20nm FWHM spectral linewidth.UV LEDs are used by Photon Systems in their NaDos personal exposure metre and TraCK trace chemical detection. These instruments are feasible thanks to the UV LEDs’ small size and low power consumption.
With great pride, Nichia Corporation presents Deep UV LED NCSU334A, a new model. Using solid-state lighting, 280nm UVC NCSU334A will be able to meet mass-market objectives for water purification and air sterilisation.
The NCSU334A, which is compact (6.8mm x 6.8mm) and powerful (55mW average optical power at 350mA), makes it possible to miniaturise systems and create long-lasting solutions where earlier technologies were unable to. Comparing the NCSU334A to traditional UV lamps, a substantial lifetime improvement is achieved.
This LED also makes use of a newly created hermetically sealed container, which makes it a very reliable product that is not as susceptible to outside environmental conditions and can therefore be utilised in many hostile settings.
