Abstract
An arc discharge lamp resistant to surface path arcing may be formed by press sealing a dielectric barrier between the electrode roots. By properly manipulating the press seal, a barrier of the dielectric envelope material may be positioned between the electrode roots. The barrier lengthens the discharge path between the electrode roots, and thereby resists surface arc discharge. The lamp seal is then protected from surface discharge heating, and light generation properly occurs between the electrode tips.
