Improvements relating to electrodeless high intensity discharge lamps.

摘要

Ballast for an electrodeless high intensity discharge lamp (14,16) includes an integrated tuning capacitor network preferably also integrated with a heat sink. A series blocking/tuning capacitor (Cs) and a parallel tuning capacitor (Cp) are integrated by sharing a common capacitor plate (30). The metal plates (30,36) of the parallel tuning capacitor (Cp) also comprise heat sink planes to remove excess heat from the excitation coil (16) of the lamp. Heat sink fins (40) can be affixed to the plates of the parallel capacitor. Efficiency is maximized by matching the impedance of the ballast load network. <IMAGE>
