Abstract
A low-loss L-C circuit arrangement for an electrodeless high intensity discharge (HID) lamp includes an excitation coil having at least one coil turn which is disposed in surrounding relation to the arc tube portion of the HID lamp and is configured in a low profile manner so as to minimize light blockage caused thereby. The L-C circuit arrangement includes a capacitor member having first and second capacitor plates which are electrically and mechanically connected to the excitation coil. The connection between the excitation coil and the capacitor member is made by a pair of connection members integrally formed with the coil turn and capacitor plates from a stock sheet of electrically and thermally conductive material.
