Claim 4

A laminated lighting device as in claim 1, wherein said layers comprise glass.

Claim 5

A laminated lighting device as in claim 1, wherein said adhesive is a polymerizable polyacrylate anaerobic sealant composition containing an acrylate terminated monomer and a peroxy polymerization initiator.

Claim 6

A laminated lighting device as in claim 1, wherein said vapor lighting means is selected from the group consisting of noble gases, mercury vapor and sodium vapor.

Claim 7

A laminated lighting device as in claim 1, wherein said second layer is transparent.

Claim 8

A laminated lighting device comprising: a base layer having an external lower surface and an internal upper surface; an intermediate layer disposed above said base layer having an upper surface and a lower surface, said intermediate layer having at least one channel formed therein, each channel forming at least one opening in said device; a top layer having an external upper surface and an internal lower surface; an adhesive sealingly contacting said upper surface of said base layer with said lower surface of said intermediate layer, and said upper surface of said intermediate layer with said lower surface of said top layer, said adhesive being capable of bonding porous rigid materials, is transparent and non-conductive and capable of withstanding high temperatures, and capable of sealing the layers without giving off vapor which would interfere with the lighting device; vapor lighting means in each channel, for emitting light in response to electrical power applied thereto.

Claim 9

A laminated lighting device comprising: a base layer having an external lower surface and an internal upper surface; an intermediate layer disposed above said base layer having an upper surface and a lower surface, said intermediate layer having at least one channel formed therein, each channel forming at least one opening in said device; a top layer having an external upper surface and an internal lower surface; an adhesive sealingly contacting said upper surface of said base layer with said lower surface of said intermediate layer, and said upper surface of said intermediate layer with said lower surface of said top layer, said adhesive being capable of bonding porous rigid materials, is transparent and non-conductive and capable of withstanding high temperatures, and capable of sealing the layers without giving off vapor which would interfere with the lighting device; vapor lighting means in each channel, for emitting light in response to electrical power applied thereto.

Claim 10

A device as in claim 7 further comprising electrode means including at least two electrodes in said channel, for applying electrical power to said vapor lighting means.

Claim 11

A laminated lighting device as in claim 7, wherein said layers comprise glass.

Claim 12

A laminated lighting device as in claim 7, wherein said adhesive is a polymerizable polyacrylate anaerobic sealant composition containing an acrylate terminated monomer and a peroxy polymerization initiator.

Claim 13

A laminated lighting device as in claim 7, wherein each channel has a depth equal to the thickness of said intermediate layer.

Claim 14

A lighting device as in claim 7, wherein said vapor lighting means is selected from the group consisting of noble gases, mercury vapor and sodium vapor.

Claim 17

A laminated lighting device as in claim 7, wherein said device comprises three or more layers wherein at least one of said layers has a channel formed therein.

Claim 20

A method as in claim 16 wherein, said forming step comprises the step of forming in said first layer at least one continuous channel design wherein each channel design has a depth equal to the thickness of said first layer.

Claim 21

A method as in claim 16 wherein said at least one channel design does not extend the full thickness of said first layer.

Claim 22

A method as in claim 16, wherein said at least one channel design is formed by etching.

Claim 23

A method as in claim 16, wherein said vapor capable of light emission is a selected from the group consisting of noble gases, sodium vapor and mercury vapor.
