Nichia NCSU434B UVC SMD LED, 280nm, 62mW

Ultra-compact design with maximum efficiency and power output

Please send us your request to

The NCSU434B high-power UVC LED from Nichia impresses with a wavelength of 280 nm and 62 mW of optical power at a size of just 3.5 x 3.5 mm. It thus has the industry's highest energy conversion efficiency in this format. Its compact and lightweight housing makes it very flexible to use. This UVC LED is exclusively suitable for applications in the industrial sector, especially for disinfection or sterilisation.

Attention: Invisible light. The LED poses a danger to the eye and the skin even with short-term irradiation. Please ask our staff for advice on this product before buying!

Nichia - world market leader in the LED industry

Nichia is the largest LED manufacturer in the world and the inventor of the blue (and therefore also white) light emitting diode. Nichia's innovative research department is always at the forefront in terms of efficiency and regularly sets new records.

Lifetime, brightness and efficiency are among the great strengths of the Nichia brand. In addition, the fine selection allows for a great added value for professional processing.

Features of the NCSU334A

  • High-Power UVC LED
  • 434 series
  • 280 nm
  • 62 mW
  • Risk group 3 (EN 62471)
  • Dimensions LED (L x W x H): 3.5 x 3.5 x 1.72 mm

Application areas

  • Disinfection (e.g. water)
  • Sterilization (e.g. surfaces, air)


  • The article is a powerful UV-C LED which can be used for the disinfection of surfaces. It emits at a wavelength of 280 nm which is not visible to the human eye.
  • It is imperative to ensure that users wear suitable protective clothing against UV radiation at all times. All skin and eye contact must be avoided.
  • We recommend the use of the following protective agents:
    • Safety goggles
    • Gloves
    • Face Shield
    • Protective clothing that shields UV light from the skin
  • Wear protective clothing at all times during use and ensure that no other persons are within reach of the radiation source without taking appropriate safety precautions.
  • Light can reflect, therefore special precautions have to be taken with reflecting surfaces (e.g. mirrors).
  • If skin tissue is exposed to the light source, skin irritation comparable to sunburn may occur. If necessary, treat the affected areas with a suitable cream or consult a physician.
  • Low wavelength UV light can cause permanent damage to the retina in severe cases. Make sure to wear protective goggles at all times when using the device.

The dominant wavelength
indicates the perceived colour of a source which is not monochromatic but in the CIE colour space. Most actual LEDs are near the pure colour curve but not on it. When connecting and extrapolating the points W (white) and P (sample), the intersection with the colour curve yields the dominant wavelength. The dominant wavelength can further be explained via the spectrum. After assessing the spectrum of the source using the V(λ) curve, the spectral centroid is determined. The dominant wavelength provides the most accurate information about the perceived colour of a source.
