With the COVID-19 pandemic, the need for disinfection has become a top priority in homes and offices. One of the most effective methods of disinfection is the use of ultraviolet (UV) light, and the use of UV disinfectant lamps has become increasingly popular. In this article, we will discuss the principle of UV disinfectant lamps and their use in homes.

How do UV disinfection lamps work?

UV disinfectant lamps work by emitting light in the UV-C spectrum, which has a wavelength of 200-280 nm. This wavelength is highly effective in killing bacteria, viruses, and other microbes, as it destroys their DNA and prevents them from reproducing. UV disinfectant lamps are commonly used in hospitals, laboratories, and other facilities that require a high level of sterilization.

How to choose a UV disinfection lamp for home use?

When choosing a UV disinfectant lamp for home use, there are several factors to consider.

First, it’s important to choose a lamp with sufficient power to effectively disinfect the intended area. A lamp with a power rating of 30 watts or higher is generally recommended for home use.

Secondly, some UV disinfection lamps are also equipped with an ozone disinfection function, which provides additional disinfection by releasing ozone gas. However, ozone is harmful to humans and should be promptly ventilated for more than 30 minutes after use.

Third, it’s important to choose a lamp with a timer function, as exposure to UV-C light can be harmful to humans and pets. The timer will ensure that the light will only be on for the set time and will automatically switch off.

Finally, it is also important to choose a germicidal UVC lamp with tilt protection, which will automatically switch off if the lamp is knocked over or tilted at a certain angle.

Safety Precautions for UV Disinfectant Lamps

  1. UV light sources must not be allowed to reach people to avoid causing damage. Ultraviolet light has the most obvious effect on the human skin and eyes.
  2. When disinfecting the surface of goods with UVC, the irradiated surface should be directly irradiated by UVC, and the irradiation dose should be sufficient, otherwise, the disinfection effect is not good or ineffective, and the disinfection purpose cannot be achieved.
  3. The suitable temperature range for UV disinfection is 20 ℃ ~ 40 ℃, the temperature is too high or too low will affect the disinfection effect.
  4. The application should also pay attention to the wiping and cleaning of the lamp. When the new lamp is used, the lamp can be wiped with 75% alcohol gauze to remove dust and oil stains from the lamp pollution. During use, wipe regularly and do a good job of cleaning the lamp, so as not to affect the purple transmission rate and radiation intensity.


UV disinfectant lamps provide an effective and convenient way to disinfect homes and offices. By choosing the right lamp and following safety precautions, you can effectively eliminate harmful bacteria and viruses from your environment.
