First, LED consumes less energy means less consumption of resources, which reduces the power loss during the energy efficiency and environmental pollution due to power generation.
According to information, in China, accounting for 70% thermal power, which contain large amounts of mercury in coal. Therefore, the average mercury released per kilowatt constant 0.152mg, and if taken every mg of mercury contamination of groundwater constant of 20 tons, each produce more electricity, will cause three tons of groundwater contamination. Similarly, the carbon dioxide emissions constant for 0.997kg / kwh, electricity consumption means that each will 0.997kg of carbon dioxide emissions per 1 kWh equivalent amount of carbon dioxide each year 71 adult cedar absorbed.
Second, compared to traditional light sources concerned, LED contains less harmful substances. Most of the traditional light source contains a large number of gaseous harmful substances, when light damage be dangerous, cause injury when handled. LED solid containing only a small amount of this substance, avoiding the breakage of harm, we recovered is also very convenient when the separation processing.
