【摘要】 LED是继传统光源之后的新型光源。它具有高光效,节能,寿命长等诸多优点,在各领域得到越来越广泛的应用。但是由于其独特的发光原理和光谱特性,一方面其光安全性问题得到人们越来越多的关注;另一方面它对人体的光生物效应也引发了学者更深入的研究和重视。该文简要介绍了LED的发光原理,及其对人体安全性的评定标准,通过LED对人体可能产生的伤害和对人体的生物效应两方面进行阐述,以期研究者在今后的应用中能慎重考虑,既充分利用LED对人体的光生物效应,又要结合安全性考虑,采取科学适当的应用方式。更多还原

【Abstract】 the LED is the light source after traditional light sources. It has high efficiency,energy saving,long life and other advantages,have been widely used in various fields. However,due to its unique spectral characteristics of light emitting principle and,on the one hand its light security had got more and more attention to researchers; on the other hand it ’ s biological effects on human body also causes the scholars further study and attention. Introduced the principle of LED light,and its implications for human safety assessment standards through LED to the human body may have hurt and both biological effects on the human body,and to researchers in the future application of extreme caution,take full advantage of led light effects on the human body and combines safety,appropriate application of science.更多还原
