LED相控调光与有关NEMA标准

介绍了LED常用调光控制方法和特点。实用中，LED的调光控制特性是所有电光源中最好的，LED具有调光动态特性好、调光控制范围宽、发光效率高和调光分辨率高等一系列优点。分析了不同的LED调光控制方法会使LED灯具有不同的工作特性。最后介绍了LED相控调光的实现与有关方法，NEMA推出的有关SSL照明标准与用途。

LED Phase Dimming and Relative NEMA Standards

The LED＇s Dimming methods and dimming properties, are introduced .In practice, LED＇s dimming properties are best over all electrical light source. LED has dimming dynamic property good, dimming rang big, lighting efficiency high, dimming solution high etc advantages. But different dimming methods have different dimming property.The LED phase dimming control/s implementation, relative technical methods, NEMA newly put out SSL relative standards and their applications are presented.
