ABSTRACT:
The present invention is directed towards a lightweight, sealant-free, thin glass envelope having a front surface and back surface laminated and integrated together, i e. specifically, a unitary envelope body having at least one discharge or ionizable gas channel. The glass envelope exhibits a weight to area ratio of .ltoreq.1.0 g/cm.sup.2. Lightweight, internally channeled light-emitting devices can be formed from these thin glass envelopes by etching electrodes to the envelope, at opposite ends of, and in communication with, the gas channel which contains a discharge or ionizable gas.
