Mercury is one of the essential metal elements in traditional UV lamps. Since the United Nations Environment Program officially announced that more than 140 countries have reached an agreement on the first international convention to limit mercury emissions, the International Convention for the prevention and control of mercury pollution. The production and trade of mercury containing products will be monitored and restricted globally to reduce the environmental damage and human health effects of mercury pollution.

According to the Convention, the production, import and export of mercury containing products are prohibited before 2020: batteries, except button batteries used in implantable medical devices; switches and relays; some types of fluorescent lamps; soap and cosmetics. This thunderbolt is undoubtedly a blow to some UV light source manufacturers.

However, how will UV light source develop under the condition of environmental protection?

Nowadays, UV LED light sources are becoming more and more popular. From the perspective of energy saving, the 5kW exposure machine using mercury lamp works 350 days a year and works 24 hours a day. The industrial electricity price is 1.08 yuan / kWh, and the electricity cost alone is more than 130000 yuan a year. This is not a small expense for enterprises. In contrast, under the same technical parameters, according to the above calculation method, the annual electricity charge of UV LED exposure machine is only less than 15000. Such a huge gap, careful boss must consider.

Mercury lamp will be out of the historical stage is an irresistible trend. UV LED will be more mature and popular in the future.
