[Foreword]: In recent years, green environmental protection has become the theme of world development. At the same time, China's lighting industry has also ushered in a new era of "green lighting." Energy-saving lighting is an important connotation of green lighting, and energy conservation and emission reduction is also a national macro policy. On December 20, 2007, the Ministry of Finance and the National Development and Reform Commission issued the Interim Measures for the Administration of Financial Subsidy Funds for Efficient Lighting Products Promotion, which provided real economic support for the promotion of energy-saving lighting. However, in the energy-saving promotion in 2008, due to poor channels and low consumer awareness, the promotion was blocked.
In this context, Sohu.com focuses on the large-scale interview promotion program with the theme of “green lighting†and “energy-saving lightingâ€, interviewing relevant government departments, lighting industry associations, and deepening energy-saving lamp manufacturers and consumers. Promote the role of the media in the promotion of green lighting concepts and energy-saving lamps.
Foshan Lighting is one of the pioneers in the history of China's lighting industry.
[Reporter]: First of all, thank you for accepting the interview network super-female of Sohu Focus Home Network Lighting Channel. Foshan Lighting has a history of more than 50 years and can be said to be the earliest pioneer in China's lighting industry. How do you understand "green lighting"? What do you think are the actual content under the concept of "green lighting"?
Green lighting includes energy saving and environmental protection

[Zhang Kaiming]: I think green lighting is mainly reflected in two aspects of energy conservation and environmental protection:
First of all, energy saving. Energy saving is the use of new technologies, new processes, and new materials to further improve the light efficiency of light-emitting devices and replace the old low-light-efficiency products. Under the premise of satisfying the same lighting effect, the power of the light emitting device is reduced, and the electric energy is saved. We can count the accounts:
As we all know, China's electricity is mainly based on thermal power generation. Each saving of electricity is equivalent to 0.36 kg of standard coal. I checked the information: 0.36 kg of standard coal combustion will release 0.943 kg of carbon dioxide, 3 g of sulfur dioxide, and 2.66 g of nitrogen oxides into the atmosphere. According to the data published in the 2007 China Electric Light Source Industry Production and Marketing Market Research Report released in February 2008, China currently has 11 billion electric light source devices, and after using it (including exports), it consumes about 660 billion kWh (each). Light bulbs 30W*2000h*11 billion), if you save only 20% of electricity by using high-efficiency lighting devices, you can save 132 billion kWh per year. It is equivalent to the re-investment of 1.5 Three Gorges hydropower stations, which can emit 124.4 million tons of carbon dioxide, 396,000 tons of sulfur dioxide and 351,000 tons of nitrogen oxides. The environmental significance of reducing room temperature gas emissions and other room gas pollutant emissions is self-evident.
In terms of environmental protection, the other is the emission of toxic substances. At present, the energy-saving products that everyone talks about, in addition to LEDs, mostly refer to high-efficiency illumination sources such as fluorescent lamps, electronic energy-saving lamps, electrodeless lamps, and high-intensity discharge lamps. These lamps all use mercury as an electrical conductor, and high-intensity gas discharge lamps also incorporate metal halides to change the characteristics of light. In order to ensure the life of the light source, the average manufacturer will add an excess of mercury. After the end of their life, these light sources are thrown away by the user. The mercury is emitted into the environment around us. Mercury is a liquid metal that is extremely harmful to the environment. It can cause health problems by entering the human body through various means. Therefore, further reducing the use of mercury in the light source and the harm to the environment is also an important manifestation of green lighting. Through the promotion and use of the "amalgam" technology, we can accurately quantify the use of mercury, and at the end of the life of the light source, mercury is also consumed, which is of great significance for reducing environmental pollution.
