The preparation and performance of LED bulbs
As already mentioned, the action of an LED bulb can only be measured when measuring their total energy expenditure. This includes the production, including transport and disposal.
In LED bulb is striking that their use, as well as accounts for the other two bulbs, most of the entire energy demand. For the production of LEDs in 2011 but also had a lot of effort for the packaging to be expended – more than for incandescent bulbs and energy-saving lamps. This disadvantage ensures that the entire energy consumption of an LED was only slightly smaller than the energy saving bulbs.
Furthermore, the three bulbs were studied in fifteen categories, which are divided into four main categories:
- Resource action
- hazardous waste landfill
- radioactive landfill
- harmless hazardous waste landfill
- terrestrial ecotoxicity
- Ground action
- Damage to ecosystems
- land use
- Water exposure
- aquatic ecotoxicity
- aquatic freshwater ecotoxicity
- Air exposure
- human toxicity
- Deplete the Ozone Layer
- photochemical oxidation
- global warming
Because of their low effectiveness, the light bulb has the greatest negative impact on the environment in all 15 categories. The action of the LED is much lower compared to the bulb and slightly smaller than the energy saving lamp. The latter can be compared to the only LED points hazardous waste landfill in the area, but cuts in all other categories underperformed. The LED intersects the reason from worse because it has a large existing aluminum heatsink. As the efficiency of LED lights over the years will be better, even this heatsink should shrink.
The environmental tests of the study are based on the claims of the US Environmental Protection Agency . In the test, it was investigated whether there is one of the 17 potentially toxic elements and if so, whether this exceeds the allowable percentage.
All lamps and their materials have been completely exposed to simulate how problematic it would be when the materials would seep into the groundwater. Much of the tested LEDs RECOURSE with its elements within the requirements. Almost all phosphors (regardless of technology) exceeded at least one restriction that applies to the state of California. These include in particular copper, zinc, antimony and nickel. The vulnerability affected were the screw base, ballast, and filaments.
On the whole, the concentration of the to be found in LEDs elements which is comparable in mobile phones and other electronic devices.
As is clear from this article, is the energy consumption, the one light source needed for operation, responsible for the majority of energy consumption. For this reason, it makes sense that in the future more and more resources are then invested continuously to reduce the power consumption of LEDs.
The next largest impact on the environment coming from the manufacturing process of the heat sink, which will turn automatically smaller over the years, when LEDs are more energy efficient. The heat sink is the only reason why LED higher values in the hazardous waste landfill achieve as energy saving lamps.
Although LED bulbs were already superior to 2012 Energy saving bulbs from the perspective of LEDBULBBAY, be in the future, as more and more consumers use this product, measures for recycling play a greater role. There must be found a way, in particular to be able to reuse the aluminum.
