UV-C LED module, USB-C, 275nm, 1 LED, 30x30mm, 5V, 3.5mW

Our basic experiment, which you can download as a PDF below, shows you how to use the small UV-C USB module in a practical application.

Pragmatic and simply good: Flexible UVC solution for the practical implementation of disinfection tasks

Our compact disinfection module measures only 30 x 30 mm and is equipped with a UVC LED. The 5 V power supply is provided via a USB-C connection, thus enabling both stationary and mobile UVC solutions. For example, the square module can be operated on a notebook, with a power bank or via another supplier. This results in a multitude of applications:

• Experimental prototypes for research purposes
• Exploratory model buildings to provide an insight into the area of ​​application
• Sophisticated DIY projects: individual pieces and small series for the targeted disinfection of "hot spots"

Up to 5 modules can be connected to each other if the power is supplied via the USB-C connection. If the power is fed in via the terminals, a larger number of modules can also be combined, depending on the power of the power pack. They can either be arranged in a line or realized in other forms. The blue status LED, which lights up as soon as the UV LED is active, ensures safe operation.

With the UVC solution, everyday objects can be transformed into sterilizing devices!

An ordinary wooden or plastic storage box can be turned into an effective disinfection unit. The modules are distributed within the closed interior – attached with adhesive pads. An even distribution of UV rays is supported by reflective material (such as aluminum foil). The object can be placed in the middle of the box on a grid shelf.

Not all items can be packed in a box, e.g. B. a mobile hand lamp can help. With a linear arrangement of the UVC modules on a carrier, powered by a power bank, hygienic cleanliness can be achieved on various surfaces; such as E.g.: door handles, clothing or laptops. In this way, cleaning without chemicals can also be carried out on sensitive surfaces.

A mini air purifier can be realized in combination with a fan and HEPA filter. The air flow is guided through the HEPA filter in a completely sealed "tunnel" and then irradiated with UVC rays. Here, too, a reflective material can support the sterilizing effect.

Warnings

• The article is a UVC module that can be used to disinfect surfaces. It emits at a wavelength of 280 nm, invisible to the human eye.
• It is imperative to ensure that users wear suitable protective clothing against UV radiation at all times. Any skin and eye contact should be avoided .
• We recommend using the following protective agents:
  • safety goggles
  • Gloves
  • Face Shield
  • Protective clothing that blocks UV light from the skin
• Wear protective clothing at all times during use and ensure that no other persons are within range of the radiation source without appropriate safety precautions.
• Light can reflect, so special precautions must be taken with reflective surfaces (e.g. mirrors).
• If skin tissue is exposed to the light source, skin irritation can occur, comparable to sunburn. If necessary, treat the affected areas with a suitable cream or consult a doctor.
• In severe cases, low-wave UV light can cause permanent damage to the retina. It is IMPERATIVE to wear safety goggles at all times when using.
