UV-lamps: disinfection of surfaces was never before easier!


What a lot of people do not know: UV-lamps are perfectly suited for disinfection! They render micro-organisms such as viruses, bacteria, yeasts and micosis in the water, in the air and on surfaces harmless!

However, even more is possible with UV-light – conditional on the light’s wavelength. Let us explain to you what that is and what it depends on!



Therefore, we will outline the rough basic information (as a kind of simple description):

The human being can perceive many colors and much of light. However, there is light invisible for people.

For example, the infrared light which is connected to the visible red light. In technical lighting, the electro-magnetic radiation of infrared light is used for sensors (see passive infrared sensor technology).

On the other hand, you have ultraviolet light (=UV – or also called black light) connected to the visible violet light.

UV-light is subdivided into the classification of UV-A, UV-B and UV-C-light. This classification depends on the wavelength of light. We know UV-A and UV-B-radiation from the sun – it causes the undesired sunburn.

UV-A-light is quite close to the visible violet light – colloquially also called black light. It has less energy and is applied for the hardening of photopolymers, in photochemistry or also in reprography. UV-A-light is also used for insect control.


Thanks to its antibacterial effect (often in combination with UV-A-light) UV-B-light is often used in light therapy. UV-B-light can relieve itching of certain skin diseases and can also help people suffering from actinic dermatitis.


UV-C-light has short wave infrared radiation and provides most of energy. This is the reason why UV-C-light is used in systems for the removal of bacteria, i.e. disinfection systems. The range of application goes from medical equipment to air, water and food. UV-C-light kills viruses, germs and bacteria. At the same time this light is uncritical for the human being – it neither penetrates skin nor the sclera of the eyes. Viruses and bacteria are much smaller than the human cells and thus can be destroyed by UV-C-light. Hence, UV-C-light is applicable for combatting tuberculosis viruses and influenca virus infections; it is even used to combat the multi-resistant germ staphylococcos found in hospitals.
