In addition to transform component technologies, recycling technologies and management strategies should be followed up to ensure the heavy metals that is recovered the LED and energy-saving lamps can be recycled . In the existing regulations of U.S. federal and California state government, through the application based on the life cycle impact assessment and hazard-based approach to assess whether these bulbs be classified as hazardous waste products. The methods based on life cycle impact is different with conventional life cycle assessment (LCA), it is necessary to quantify the potential toxic elements in LCA. Saving lamps and LED lamps are grouped into hazardous waste, as loss of lead has been extremely too much (respectively, 132mg / L and 44mg / L, and the safety requirements is 5), and high levels of copper (111000mg/kg and 31600mg/kg, and safety standards is 2500), lead (CFL bulb is 3860mg/kg, safety standards is 1000) and zinc (CFL bulbs as 34500mg/kg, safety standards is 5000), while incandescent bulbs are not dangerous. Note, the mercury vapor is not considered in CFL lamp results,which wasn’t captured in the experimental sample preparation process. Compared with incandescent lamps, energy saving lamps and LED lamps have a higher potential causing resource depletion and toxicity, mainly because they have a high aluminum, copper, gold, lead, silver and zinc. LED has the highest potential toxicity, mainly due to copper and aluminum, followed by energy-saving lamps, as the main metal is copper. These results are different with toxic potentially indicators ( TPI) the results. TPI results show that why the energy-saving lamps has the highest toxicity maybe because mainly zinc and copper, followed by the copper the LED contain. The incandescent contain aluminum, copper, nickel, but the amount is low result in a small toxicity potential. Energy-saving lamps have the highest potential for human toxicity and ecotoxicity, LED followed. The human toxicity and ecotoxicity of CFL 2.5 times higher, respectively, 1.3 times than that of the LED and incandescent two orders of magnitude. Inspect the metal elements of lamp relative contribute to human toxicity and ecotoxicity, zinc and copper are the highest, accounting for 89, 98% and 74-89%. In summary, the potential environmental impact of the energy-saving lamps and LED lamps are 3-26 times and 2-3 times higher than of incandescent The current technology of the energy-saving lamps and LED bulb needs to be further developed to reduce overall resource consumption and toxicity potential. Weigh the comprehensive benefits and costs,assessment that evidence from the DfE life cycle perspective,it is necessary to find alternative materials to minimize aluminum, copper, gold, lead, silver and zinc. Another method is to develop the saving lamps and LED lamps which have the longer life, so that reduce the use of new resources and the amount of waste. Therefore, in the lighting product development, follow the conservation and sustainable development policies, in addition to improving energy efficiency, should also focus on developing some technology to reduce rare metals content without under the premise of affecting the performance and life. From the perspective of resource recovery, some of the metal bulb is actually very limited. Therefore the appropriate waste management measures is urgently needed, or through innovative technology to reduce toxic substances, metal content, or to extend lamp life. The test objectively describes that the LED lighting is not the same environmental protection as widely publicized now, but it adopts the semiconductor material, and it have some harm to the environment more or less, we’d better not refuse LED lighting, after all, as the third generation of green lighting human beings developed, its energy-saving effect is very significant, the initial phase of any new thing is not perfect, LED lighting has only 70 years history from invention to now, LED needs to improve radically from the material, use less heavy metals to achieve more with environmental protection, Lead lighting has been strictly applying o qualified LED chips, heat sinks, drivers, baffles and other materials whose heavy metals within the standard range, and constantly improving the production and R & D team, determining to produce more environmentally friendly and inexpensive LED flood light, LED tunnel lights, LED lamps and other indoor and outdoor lighting to meet the needs of our lives, log www.lead-lighting.com to find more comprehensive LED lighting.
