Nichia SMD LED UV NCSU276A 365nm 780mW at 500mA 1.9W 1x1cm Square PCB

Introducing our PCB LED modules that make it easy to incorporate high-performance Nichia LEDs into your application, without the need for reflow soldering or a sophisticated soldering station. The 10x10mm square PCB is made in Germany to the highest quality standards, ensuring superior heat transfer and the longest LED lifetime. The solder pads are easy to connect with a basic soldering iron, making it a great choice for small projects, rapid prototyping, or custom builds.

Nichia is one of the largest LED manufacturers in the world and inventor of the blue (and thus also white) light emitting diode. Their innovative research department is a pioneer in efficiency and establishes records on a regular basis. The Nichia brand is known for its durability, brightness, and homogeneity. Additionally, the fine selection allows for greater added value for professional processing.

Our Nichia SMD LEDs in the range of UV light can be used for a wide range of applications. The NCSU276A is available with three different wavelengths, including 405nm, 385nm, and 365nm. At 365nm, this Nichia UVA LED reaches a radiant power of 780mW, making it ideal for disinfection, plant growth, ink or resin curing, lithography for medical, industrial, and commercial applications.

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.
