Highlights: Simple LED environmentally friendly lamp-EEWORLD

Collect

The adoption of LEDs has brought a new revolution to light bulbs, which are no longer limited to the original round shape. However, conventional LEDs still use plastic shells. This lamp designed by designer Tien-Ho Hsu is not only energy-saving, but also very environmentally friendly. The shell of the lamp is made of reusable recycled paper. The lamp can also rotate. This design participated in the 2011 Lite-On Innovation Design Award.

Analysis of application problems of electronic transformer in driving LED-MR16

LEDs are widely used in E27, GU10, PAR lamps, MR16 and other fields. However, there are some problems in the application of LED-MR16 driven by electronic transformers. This is mainly caused by 4 reasons: 　　First, the power of the MR16 lamp cup of LED is usually only 5W, and the magnetizing current generated in the

Introduction to LED Radiation Safety Test Standard EN62471

IEC 62471:2006 & EN 62471:2008 will be officially implemented on September 1, 2009. From now on, all LED lights must be tested according to this standard. The transition period is one year. The original IEC/EN60825-1 report can still be used, but it will be completely invalid from September 1, 2010. At present, so
