Title:
EXTERNAL ELECTRODE DRIVEN DISCHARGE LAMP
Document Type and Number:
WIPO Patent Application WO1999049493
Kind Code:
B1
Abstract:
A discharge lamp (20), such as a neon lamp, comprising a laminated envelope having a gas-discharge channel and at least one external electrode (44) in communication with the gas-discharge channel (20), the laminated envelope having a front surface (32) and a back surface (28) integrated together to form a unitary envelope body essentially free of any sealing materials. The external electrode (44) comprises an electrode surface integral with the laminated envelope and a conductive medium disposed on the electrode surface. The conductive medium may be conductive tape, conductive ink, conductive coatings, frit with conductive filler or conductive epoxies. The discharge lamp may comprise a laminated envelope including a plurality of separate gas-discharge channels and external electrodes in communication with the gas-discharge channels, whereby the discharge is driven in parallel.
