Abstract
A high intensity discharge lamp includes a dielectric substrate, a first electrode near the dielectric substrate, a second electrode spaced from the first electrode and near the dielectric substrate, a conductor spaced from the dielectric substrate, and adapted to provide a current return from one of said electrodes to an electrical driver circuit, and at least one metal element near the dielectric substrate. The electrical driver circuit is constructed to produce an electric potential sufficient to cause an electrical breakdown of a medium between the electrodes. The lamp and metal element are also arranged to enable a coolant to flow adjacent to at least one surface of the dielectric substrate to transfer heat from the dielectric substrate to the coolant.
