Doubts raised over the prospect of LED light source again recently, such as “LED is energy-saving but expensive”, “LED is neither energy-saving nor economical”, “The aftermath of LED frenzy emerged”, “It repeats the same failure of PV industry”, “The complete application of LED lighting in public areas is dangerous”. After such an upheaval, the industry has begun to reflect on the future development direction of LED light source.
                                                   
In recent years, we often heard it said that the higher requirements for chip, the higher the waste in production process, so there will be considerable energy consumption. If the overall energy consumption of LED lamp in the whole production process far outweighs that of theincandescent lamp or the compact fluorescent lamp, then how can we achieve the energy-saving effect of LED?
 
Some argue that the small and easy-to-control LED light source will make the appearance design of fixtures more diversified, while the appearance of incandescent lamp or compact fluorescent lamp is rather simple. However, it spends more energy and materials to achieve the diversified design. Despite the varieties of visual experience LED light source could bring, insiders claim that it’s understandable to pursue better life, but it needs more considerations on that if we have to waste more energy to achieve this aim. After all, the emphasis of utilizing LED light source is the effect of energy-saving and environmental protection.
 
Is the whole production of LED lights against the aim of energy-saving? It still needs experts, manufactures and related institutions to do research on the energy consumption of all aspects of the whole production process and make it clear to industry practitioner and members of the public.
