摘要

1.Introduction The worldwide concept of energy conservation and environmental protection has boosted the rapid development of LED industry for more than ten years,and it is in the blooming period right now.It has kept increasing penetration rate and hundreds of billions of output value for years.On the other hand,homogeneous competition results in not optimizing the added-value of LED lighting products and the dropping of terminal price;it consequently makes serious internal friction and survival crisis for many enterprises.Some new concepts are introduced into LED industry every year as users'demand,but they have not fundamentally solved the technical problems of LED.
