The reduced electromagnetic interference from led lamp drive device

Abstract

This paper presents the method to reduced electromagnetic interference from electronic drive for LED lamp to achieve the TIS standard No.1955-2551. According to standard, it must have been tested for magnetic field compatibility that are included Magnetic Field Emission: ME, Conducted Emission: CE and Coupling Decoupling Network: CDN. The 3 LED lamp which defined as Type A, B and C were tested. Each lamps has 16 watt electric power and was different electromagnetic interference of electronic drive. After that, the reduce electromagnetic interference circuit has been designed for low frequency. This circuit test was based on Conducted Emission test only. The integrated design was preferable to reduces electromagnetic interference for LED lamp drive device type A to the TIS. standard No. 1955-2551. That design circuit was been trialled in LED lamp drive device type B and C in order monitor efficiency of reduce electromagnetic Interference. The results showed that design circuit can reduce electromagnetic interference from LED lamp drive device type A and B to the standard. For LED lamp drive device types C, the design circuit can reduce electromagnetic interference, but it still has not achieve the standard.
