Ozone Generation by Far UV-C Lamps

 

Another safety-related concern connected to Far UV-C-based applications is the potential to generate ozone. The primary focus of this section is on photochemical formation (and decomposition) of ozone; however, it should be noted that ozone may also be formed as a result of corona discharges, which are associated with some Far UV-C sources. Moreover, the accumulation of ozone in ambient air will be governed not only by reactions that lead to formation and decay of ozone, but also air circulation and mixing in the vicinity of the Far UV-C source.

What is UV lighting?

Ultraviolet light (UV) is a type of naturally present electromagnetic radiation that is in sunlight and actually makes up approximately 10% of the total light generated by the sun. UV light is electromagnetic energy with wavelengths shorter than visible light but longer than x-rays (see image below). 

The wavelength of this light ranges from 10nm to 400nm and is classified into three sub-bands; UV-A (near), UV-B (middle), and UV-C (far).

UV light with wavelengths less than 290nm are considered to have “germicidal” properties (more on this below). Earth’s atmosphere absorbs ultramagnetic radiation with wavelengths less than 290nm, meaning that most of the UV-C and UV-B generated by the sun is blocked by our planet’s ozone.
