Wu Yulin: Five reasons why energy-saving lamps must be abandoned from a health perspective

　　 On June 2, Chairman Xi of the Central Committee delivered an important speech at a symposium of experts and scholars presided over. He said: “At this time of the epidemic, we resolutely, in order to prevent and control the epidemic, to the economic and social The development has pressed the pause button, and at a high price, we put people’s lives and health first. People’s lives are only once and must be preserved. Everything we do is based on this principle.'

　　Through the Chairman’s important speech, we can see that the people’s life and health are the first, and we must proceed from this principle in everything we do. However, there are still many things around us that have not fulfilled the principle of 'putting life and health first'. For example, in many places, there are still unhealthy behaviors of using old fluorescent energy-saving lamps in public spaces.

　　Why is it unhealthy to use fluorescent energy-saving lamps?

　　 1. Fluorescent energy-saving lamps use liquid mercury (commonly known as 'mercury') as the light source exciter, and 'mercury' itself is It is toxic and pollutes the environment. 1g of mercury can pollute 80t of water, adversely affecting human health, and threatening people’s lives. Therefore, on January 19, 2013, the United Nations Environment Programme adopted the 'Minamata ConventionThe damage caused. 128 countries and regions around the world have signed this convention, and my country ratified the 'Minamata Convention on Mercury' in April 2016. According to the requirements of the Convention, the contracting states will ban the production, import and export of mercury-containing products starting in 2020.

　　 2. Fluorescent energy-saving lamps flicker too severely, which is very harmful to human eyes and seriously affects people’s vision health. Fluorescent energy-saving lamps generally use electronic ballasts, which are prone to large-scale strobes, and even some strobes can be detected by the human eye. This kind of stroboscopic easily causes eye fatigue and is not conducive to close reading/writing.

　　 Third, the spectrum of fluorescent energy-saving lamps is a discontinuous spectrum, especially the blue light spectrum is obviously higher, and too high blue light has greater damage to human eyes. The sunlight in our daily life is a continuous spectrum, and the spectrum curve is full and smooth, which makes people feel comfortable. The discontinuous spectrum of fluorescent energy-saving lamps is like a wave, some of the spectrum is too high, some of the spectrum is too low, and whether it is too high or too low, it will have an adverse effect on human health.

　　 Fourth, the fluorescent energy-saving lamp uses a glass shell, which is easily broken. Once the glass shell is broken, the liquid mercury inside will volatilize into the air, polluting the air. Moreover, the fluorescent energy-saving lamps also need to use a large amount of glass and mercury in the production process, and there are also environmental protection problems. Under such circumstances, fluorescent energy-saving lamps will pollute the environment from production to use, and environmental problems will arise. People come and go in public spaces, and once fluorescent energy-saving lamps have environmental problems, they will harm the crowd.

　　 5. Fluorescent energy-saving lamps have certain defects in color temperature selection, display index performance, stroboscopic, glare, etc. These defects have a bad effect on human health, so they need to be used with caution. Moreover, compared to LED lamps, fluorescent energy-saving lamps are not 'energy-saving

　　Comparing the energy-saving lamp spectrum with the sunlight spectrum, it can be seen that the energy-saving lamp spectrum has many colors of light missing. Long-term work and life under the lack of light in this spectrum will have a certain impact on people's physical health and mental health. For example, the lack of red light and yellow light will increase the risk of depression and fatigue; the lack of infrared light will cause a decline in immunity and skin deterioration; the lack of green light will affect digestion and body balance.

　　 In summary, from a health perspective, we must give up the use of energy-saving lamps, and switch to more efficient, healthier, and more advanced light health LED lamps.
