Can deep ultraviolet leds replace mercury lamps?

As we all know, mercury is highly toxic, mercury leakage has a very serious harm to the human body and the environment. In 2020, China has signed the Minamata Convention, which prohibits the production and sale of mercury and products containing mercury. 128 countries have signed the Minamata Convention, which also shows the attitude of mercury lamps.

 

Deep ultraviolet LED has the advantages of low power consumption, fast start-up, long life, small size, good sterilization and disinfection effect, long life and so on. The key UVC-LED will not produce secondary pollution in the use process, high environmental performance, therefore, UVC-LED is being favored by more consumers, and it is also a better alternative to mercury lamp. If it is equipped with high-power deep ultraviolet LED lamp beads in a sealed space, it only takes ten seconds to destroy bacteria. According to the third party test report, UVWORKS sterilization module can reach the highest sterilization rate of 99.99%, small size and easy to carry.

 

The sterilization time of mercury lamp is generally more than ten minutes, but due to high pressure, ozone generation, high power consumption, long sterilization time, heavy equipment, etc., the scope of daily use is limited

 

Deep ultraviolet LED and mercury lamp mainly have the following differences:

 

1. Different light sources: Deep ultraviolet leds emit ultraviolet rays through beads, while mercury lamps emit light sources through mercury tubes or bulbs

 

2. Different spectra: Deep ultraviolet LED refers to the band of 220-285nm, which is the spectrum of single peak wavelength emission, while mercury lamp is the spectrum of continuous wavelength emission, which has a relatively large wavelength range

 

3. Different energy consumption: Due to the different luminous principle, deep ultraviolet LED is more energy saving and environmental protection than mercury lamp

 

4 Different heating: deep ultraviolet LED is single peak wavelength, the effective part is more prominent than mercury lamp, and does not produce additional infrared wavelength, so it does not produce additional thermal radiation, more practical for heat sensitive materials

 

5. Different safety factor: Because mercury lamp uses high pressure excited mercury vapor luminescence, once mercury lamp tube is damaged, there will be heavy metal mercury element leakage, which may seriously cause heavy metal poisoning of on-site personnel, but deep ultraviolet LED does not have these problems

 

 

On the whole, compared with traditional mercury lamp, deep ultraviolet LED has many advantages, such as not fragile, impact resistance, stable voltage, fast opening speed, no need to preheat, especially in the aspect of environmental protection and energy saving, no heavy metals and other secondary pollutants, the light source can save up to 70% energy, and in line with the European Union hazardous substances restriction requirements (RoHS standard)

 

Qingdao fluorescent UV disinfection products mainly include air sterilization, surface sterilization, water sterilization, medical sterilization and other products. The company has a professional post-doctoral team, focusing on the research of ultraviolet sterilization applications, after years of deep research in the ultraviolet industry, the company has obtained a number of national invention and utility model patents. At present, a number of sterilization module products have been put into the market.
