According to a recent report by the United States Department of Energy (DOE), the importance of LED lighting is that it has a lower impact on the environment and a slight super fluorescent light (CFLs) compared to white light bulbs. The report "Manufacturing and Utility of LEDs" is mainly about comparing the life cycle of these three different bulbs, including production, operation and elimination. This report provides a comprehensive study of LED bulbs to analyze the energy and environmental impacts of the production, assembly, transportation and elimination of these three different bulbs. This is also the first report to publicly discuss LED production processes, supporting the Department of Energy to protect the public's air and water resources, improving the competitiveness of US clean energy, and assisting households and general companies to save energy bills.
This is the second large report of the Department of Energy to assess the environmental resource costs of the LED bulb life cycle compared to conventional bulbs.
This report follows the previous report, the conclusion of "Review of the Lifecycle Energy ConsumpTIon of Incandescent, Compact Fluorescent and LED Lamps" published in February 2012, and continues to make a more detailed evaluation comparing three different lighting sources. Widespread impact on the environment.
The report points out that traditional fluorescent lamps (CFLs) and LED lamps are very similar in terms of energy consumption. Both consume less energy than white light bulbs, and consume much of the life cycle compared to manufacturing and transportation. energy. Because of the high efficiency of operation, it consumes 12.5 watts of power and can achieve the same effect as CFLs (15 watts) and white light bulbs (60 watts). Of the 15 tests in the report, 14 showed that the LED bulb is the most environmentally friendly of the three types of lighting.
In addition to the predominance of discarding, all aspects of the test show that CFLs have a greater impact on the environment than LED bulbs. The precipitation of the aluminum alloy inside the LED will cause great damage to the landfill. According to DOE's report, in the next five years, based on short-term improvement technologies, the impact of LEDs on the environment will be smaller than today's impact.
When market-oriented to save money for customers and companies, from white-light bulbs to energy-efficient lighting, the environmental impact of LED lights and CFLs, we expect to reduce the current 3 to 10 times.
