Abstract
We described the operating principles of two different type of igniters for lightning of Ceramic Metal Halide Lamp(CMHL) and also provide some useful comparisons. One is for magnetic ballast, the other one is for electronic ballast which operates lamp by low-frequency square-waveform. Ignition voltage of lamp depends on the structure of igniter, such as the length and electrical characteristics of cable, which make troubles for ignition in real sites. Therefore, we measured and analyzed ignition voltages from igniters which are used in magnetic and electronic ballast in cables at a distance of 5 meters between a lamp and a igniter to suggests an applicable solution in real sites.
