| Abstract |
LED lighting has received worldwide attention as advantages, such as environment-friendly than the conventional light, the excellent energy efficiency, and a semi-permanent lifetime. The use of the SMPS increased with the rapid growth in the LED industry. Increased use of SMPS means an increase in the harmonic generation load. Therefore, LED lighting compared with conventional fluorescent lamps were tested in this paper for characterized by a light source, electrical and harmonic characteristics. Experiments results for LED lighting showed different characteristics from the existing fluorescent lamp. Especially harmonic characteristic results showed different characteristics in accordance with the power device manufacturing method for LED lighting. |
