MINIATUUR METAALDAMPONTLADINGSLAMP, DIE BIJ HOGE FREQUENTIE BEDREVEN WORDT. |
摘要 |
<p>Miniature high pressure metal vapor lamps containing mercury in a discharge volume of one cubic centimeter or less when operated at low frequencies have extremely high reignition voltages; the problem is compounded in metal halide lamps, particularly during warm-up. Ballast designs capable of coping with these conditions at 60 Hz have disadvantages. The discovery of the existence of resonance-free regions in the frequency range between 20 and 50 KHz has made stable and efficient lamp performance possible through the use of compact, practical and economical high frequency ballasts.</p> |
