LED lighting needs to focus on mercury-free product development

The Ministry of Industry and Information Technology recently reported that in order to implement the “Twelfth Five-Year Plan for Energy Saving and Emission Reduction” and “The Twelfth Five-Year Plan” of the “Comprehensive Prevention and Control of Heavy Metal Pollution” of the State Council and reduce the mercury content of fluorescent lamps, the Ministry of Industry and Information Technology has organized “China gradually reduces the number of fluorescent lamps. Mercury content roadmap” for solicitation of comments. The roadmap proposes that the goal of low-mercury mercury products and their manufacturing processes should be based on mercury-reducing technological innovations. The elimination of outdated production processes combined with the promotion and application of advanced low-mercury technologies should gradually reduce the mercury content of fluorescent lamps gesep.com products in stages. . By December 31, 2013, the liquid mercury production process for compact fluorescent lamps was eliminated; by December 31, 2014, the liquid mercury production process was completely eliminated. It is expected that by phasing out the liquid mercury process by 2014, mercury emissions from the production process will be reduced by about 20 tons compared with 2010.

The roadmap proposed by the Ministry of Industry and Information Technology as a whole circumvents mercury reduction in fluorescent lamps. Faced with the enormous pressure of energy saving and emission reduction and the green development model, reducing the mercury content is imperative. However, I believe that instead of digging innovative processes to reduce mercury content, it is better to focus more on mercury-free LED lighting.

It is estimated that the total amount of mercury used in the industry in 2011 was approximately 57 tons, of which the amount of mercury retained in the product was approximately 40 tons, and the amount of mercury emitted during the production process was approximately 17 tons. For fluorescent lamps, not to mention the reduction of liquid mercury will improve the effectiveness of environmental protection, even if the elimination of the entire liquid mercury process, into the solid state mercury injection process may be able to grasp the amount of injection in the process, regardless of the increase The cost alone is only -38.87°C from the melting point of mercury. Mercury in a fluorescent lamp placed at room temperature is still in a liquid state. The mercury in the lamp is also faced with problems such as difficulty in recycling and mercury pollution. The innovation does not solve the fundamental problem. . So, instead of reducing the amount of mercury, it's better to be truly mercury-free lighting. In July of this year, the fourth meeting of the Intergovernmental Negotiating Committee convened by the UN Environment Protection Agency for Energy Saving and Environmental Protection was held. Representatives from Jamaica, Japan and other countries proposed the elimination list of mercury-containing electric light source products.

The same is the lighting, LED with its own energy saving, high life expectancy and other characteristics is sufficient to overcome the fluorescent lamp, more importantly, the LED lamp does not need to inject mercury, can reduce the burden on the environment, in line with the concept of environmental protection, but also to bypass The international convention mercury instrument is conducive to export trade negotiations. In today's global era of green development, looking at China's development, energy conservation, environmental protection, and green development will also enter the fast lane. For the lighting industry, the elimination of incandescent lamps is a foregone conclusion, while ordinary energy-saving lamps have problems due to mercury content problems. Open environmental barriers, LED lighting is the first choice for lighting.
