Abstract
An arc discharge lamp comprises a ceramic arc tube having an electrode at each end, each electrode being mounted on a support member. A ceramic adapter is sealed to a ceramic cylinder which is sealed to the end of the arc tube. The support member extends through the cylinder into the adapter where it is connected to an externally extending lead-in wire by means of a spiral refractory-metal connector. The connector is flexible enough to withstand the thermal stresses resulting from the normal high operating temperature of the lamp.
