关于LED照明应用中的一些问题

Some Problems in the Application of LED Lighting

自20世纪60年代第一支真正意义上的商用发光二极管器件出现,到21世纪LED产品高亮度化、高效化的创新和突破,一直被冠以新一代光源之名的LED技术,正如Haize所预言的那样急速发展,并从单一的应用逐步扩张到各相关行业和领域。近年来,LED产业在内地的发展态势也可以用热火朝天来形容,虽有国外厂商强势的上游核心技术壁垒,但在国家政策支持和刚性供求关系的背景下,仍有大量的民间资本不断注入,且大部分集中于产业链的中下游领域。LED行业发展迅猛,但也就此导致了以劳动密集型为主和整体技术水平落后的产业现状。随着背光应用份额的走低及低碳节能呼声下通用照明市场规模的迅速扩大,从景观装饰性照明、户外功能性照明到商业照明,越来越多的企业已转向或加大研发的资源投入,并逐步专注于更为深入的细分领域,但其中仍存在很多类似"通病"的现象和问题值得我们关注和探讨。

Since the appearance of real commercial LED in 1960 s last century,the LED technology never stop continuing innovation and breakthrough.Like Haize said in his famous prophecy,this so-called new generation luminaire extend it 's application in many different areas.In recent years,LED industry in china develop rapidly although there are technology barriers from foreign manufacturers,but under the background of policy support and rigidity demand,there are still a lot of Private capital injection,and most of them focused on the industrial chain in the middle and lower.Many different kinds of LED enterprises,industrial park appear all over the country,also caused the present situation of the mainly labor-intensive and low-tech industry present situation.As the backlight application share lower and the general lighting application expand,under the policy of energy saving,more and more companies have turned to or increasing spending on coretechnology research,and gradually focus on professional area in decoration lighting,outdoor functional lighting and commercial lighting,but there still exist a lot of problems for us to resolve.
