To evaluate LED lights and study their actual energy consumption and resources, it is not enough to consider only the energy consumption during use. The purpose of OSA's implementation of LCA is to analyze the environmental impact of LED lamps throughout their life cycle and compare them to energy-saving bulbs CFLs and incandescent lamps. The assessment identified relevant materials and energy supplies for all components and production processes of LED lamps. In addition to detailed analysis of the various stages of production of LED chips and housings, all necessary transportation links have been studied. In addition to direct input of raw materials, energy inputs, materials and emissions associated with resource recovery are also recorded. The results of the assessment include not only the conclusions on resource consumption and primary energy consumption, but also assessments of acidification, eutrophication, greenhouse effect, ozone depletion and toxicity.
The most important factor LED high-performance Osram Light's first LCA show that even with the cumulative energy input and environmental considerations, LED lights are still an ideal alternative to incandescent lamps.
These completely different lamps are usually compared in wattage. Traditional tungsten filament lamps lag far behind LED lamps; for example, if you use an 8 W power-saving bulb or an 8 W LED lamp instead of a 40 W incandescent lamp, you can save 80% of the power.
To ensure the comparability of LCA results, the evaluation used a lifetime of 25,000 hours as a benchmark. The latest generation of LEDs (Parathom Classic A55 with GoldenDRAGON Plus LEDs) can really reach this level, but for incandescent or power-saving bulbs, you need 25 白 incandescent lamps (OSRAM Classic A 40 W) or 2.5 ç› with a life of 1,000 hours. A 10,000-hour fluorescent lamp (Dulux Superstar Classic A 8 W) can be compared.
More than 98% of energy consumption for luminescence The study was conducted in collaboration with experts from the Siemens Corporation's Centre for Eco Innovations. The results show that the LED lamp is similar to the power-saving bulb CFL, and it uses more than 98% of the energy consumption for illuminating, and less than 2% of the energy is used for production, which dispels the concern that LED production may be particularly energy-intensive. . The primary energy consumption of incandescent lamps is around 3,300 kWh, while the primary energy consumption of LED lamps is less than 700 kWh, so LED lamps are clearly more efficient than traditional incandescent lamps. In addition, the evaluation results show that LED lamps always have better environmental impact than incandescent lamps throughout their life cycle.
As LED lighting continues to improve, LED lights will be able to achieve better LCA scores in the future. Currently, three independent experts are verifying the results of this assessment within OSRAM. A review of the results of this assessment will be posted online in October.
LEDs are not only forward-looking, but their life cycle assessments also show that LEDs are one of the most environmentally friendly lighting products. 
OSRAM publishes LED bulb complete life cycle assessment (LCA) results
OSRAM's Life-cycle Assessment (LCA) Life-cycle Assessment study for LED lamps shows that the latest generation of LED lamps have performed well in environmental protection and received a very high rating. This study provides an in-depth analysis of the entire life cycle of LED lamps, the energy and raw materials consumed in the production, use and disposal of LED lamps and the environmental impacts of this process. The research results show that LED lamps have reached the LCA score of power-saving bulbs and are far superior to traditional incandescent lamps.
