UV Zero Mercury Countdown
There is a complete ban on mercury containing ultraviolet lamps
Prohibition background
Understand the European Union RoHS The background and significance of the ban on mercury containing ultraviolet lamps in the directive
The hazards of mercury
Mercury is listed by the World Health Organization as one of the top ten chemicals most dangerous to public health. Due to its toxicity, The European Union is RoHS Under orders, restrictions on the use of mercury have been tightened, A comprehensive ban on mercury containing ultraviolet lamps is an important step in reducing environmental risks.
Minamata Convention
This decision is related to "Minamata Convention" maintain consistency, This convention is a global initiative, Intended to protect human health and the environment from the hazards of mercury. Minamata Convention named after Minamata Bay in Japan, Mid century, There is mercury pollution in industrial wastewater, Causing thousands of people to be poisoned.
technological progress
Technological advancements have led to the development of safer mercury free alternatives in many fields. especially UV-LED, excimer lamp, Even lasers, Provides a promising possibility for replacing mercury vapor lamps.
technical challenge
Although many mercury containing lamps have been replaced in the field of general lighting, but in UVC The frequency band still faces significant challenges
UVC Technical difficulties in frequency bands
Wavelength difference
Traditional mercury vapor lamps and UVC-LED There are significant differences in wavelength range and radiation characteristics, New testing and characterization schemes need to be developed.
Geometric design
UV-LED Geometric Design, Spectral characteristics and key performance parameters UVC It is not easy to directly compare the frequency band with mercury vapor lamps.
system compatibility
High performance mercury vapor lamps are difficult to use simply UVC-LED System renovation, Especially in many existing water treatment equipment.
Affected application areas
Exemption and Solutions
Understand the exemption conditions of the ban and industry response plans
exempting conditions
spare parts supply
There is no time limit for the supply of mercury containing ultraviolet lamps as spare parts for existing equipment, As long as the device is available 2027 year 2 Installation before the month.
specially designed
Devices specifically designed for installation in another device that is excluded from the ban are also excluded from the ban.
large-scale equipment
UV lamps designed specifically for large tools or industrial installations may be exempted from the ban.
Solution
UV-LED technology
Enterprises and scientists are actively developing UVC-LED Solution
New standard formulation
Advanced UV for Life Members are developing UV-LED New testing standards for water treatment
Industry Collaboration
Hg-RoHS The working group is coordinating manufacturers and users to jointly address challenges
Important Notice
Even if there are exemptions, Manufacturers also have a responsibility to be clear, Clearly record which products are exempt, Which ones do not enjoy. These documents must be submitted to third parties (Like customs or end users) clear, Easy to understand and verifiable.
