ABSTRACT:
A medium pressure quartz lamp for arc discharge illumination, includes a quartz envelope having opposite electrode ends with an electrode unit sealably attached to each of the opposite electrode ends. Each of the electrode units includes an electrode rod extending into the envelope and a platform physically attached to the rod. The platform has a melting point of at least 1,000.degree. C. The electrode units also include at least one conductive, elongated metal foil which has a first end and a second end. The conductive elongated metal foil(s) are attached at their first end to the platform and attached at their second end to a terminal connector. Preferably, plural foils are utilized with a single platform attached to the electrode rod at their first ends and attached to a plurality of terminal connectors a their second ends. Present invention lamps, as a result of utilizing the conductor enhancing platform approximately doubles maximum operating current as compared to prior art lamps of otherwise similar configurations.
