Nichia SMD LED UV NCSU276C 365nm 1050mW at 500mA 1.9W Emitter

Nichia is a world-renowned LED manufacturer known for its durability, brightness, and homogeneity. Their research department is innovative and efficient, and they are credited with inventing the blue LED, which led to the development of white LEDs. The Nichia SMD LEDs in the UV range are highly versatile and can be used in a variety of applications. The NCSU276C is available with three different wavelengths, and at a 365nm wavelength, it reaches a power of 1050mW, making it highly suitable for industrial and commercial applications. Fixtures with multiple LEDs can be used for disinfection, plant growth, ink or resin curing, and lithography for medical, industrial, and commercial applications.

It is important to note that UVA radiation is invisible to the naked eye and can pose a danger to the eyes and skin, even with short-term exposure. Safety precautions, as detailed in IEC Standard 62471:2006, 'Photobiological Safety of Lamps and Lamp Systems', EU-Directive-2006-25-EC, or the applicable standard for your country, must be respected.

The NCSU276C is highly suitable for use in medical engineering, test and sorting machines, hardening, and cameras with UV light. In addition, it has a special application focus: continuous disinfection with safe UVA radiation. It functions for 8 hours daily and is safe for people, with irradiance limited to 10W/m2 at 2 meters height from the floor. It has been proven to kill up to 99% of viruses and bacteria, and its continuous disinfection efficiency has been confirmed by studies.

Irradiance estimation for a 365 nm UVA LED with 1 Watt Radiant Power: Warning UV danger for eyes and skin

UVA radiation in the wavelength range of 200-400 nm of more than 10W/m² may cause inflammation of the cornea as well as a UV erythema (sunburn) of the skin. The biological effectiveness of the UV radiation varies in the stated wavelength range and is described with the spectral response function (weighting scale) SUV. 

Safety precautions when using UV light sources must be respected, as detailed in  IEC Standard 62471:2006, ‘Photobiological Safety of Lamps and Lamp Systems’, EU-Directive-2006-25-EC or the applicable standard for your country.
