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.
Claims17
An internally channeled light emitting device comprising a thin glass envelope having a front surface and a back surface laminated and integrated together to form a unitary envelope body essentially free of any sealing materials and having at least one gas discharge channel, the glass envelope exhibiting a weight to area ratio of .ltoreq.1.0 g/cm.sup.2, each channel provided with a discharge or ionizable gas and at least two electrodes in communication with, and located at opposite ends of, the at least one gas discharge channel for generating an arc discharge therebetween.
A thin glass envelope for enclosing a discharge gas or ionizable medium for use as a lighting device, the envelope comprising a front surface and a back surface laminated and integrated together to form a unitary envelope body essentially free of sealant materials and having at least one discharge or ionizable gas channel, the front and back surfaces comprised of a glass material selected from the group of glasses consisting of borosilicate, aluminosilicate, boroaluminosilicate and soda-lime silicate.
An internally channeled light emitting device comprising a thin glass envelope having a front surface and a back surface laminated and integrated together to form a unitary envelope body essentially free of any sealing material having a primary gas discharge channel and at least one secondary gas discharge channel adjacent to and in communication with the primary gas discharge channel, channel provided with a discharge or ionizable gas, the primary gas discharge channel having at least two electrodes in communication with, and located at opposite ends of, the primary gas discharge channel for generating an arc discharge therebetween, the front and back surfaces comprised of a transparent glass material.
An thin glass envelope for enclosing a discharge gas or ionizable medium for use as light emitting device, the envelope comprising a front surface and a back surface laminated and integrated together to form a unitary envelope body essentially free of sealant materials and having at least one discharge or ionizable gas channel, and at least one secondary channel adjacent to and in communication with the primary channel.
A glass envelope exhibiting a weight to area ratio of .ltoreq.1.0 g/cm.sup.2, the envelope comprising a front surface and a back surface laminated and integrated together to form a unitary envelope body essentially free of sealant materials and having at least one channel formed between said surfaces.
