==Composite specification==
The LED Glass composite material may consist of using transparent metallized glass<ref>Hahn, T., EP0900971A1 [http://v3.espacenet.com/publicationDetails/biblio?DB=EPODOC&adjacent=true&locale=en_EP&FT=D&date=19990310&CC=EP&NR=0900971A1&KC=A1 "Lighting device containing LEDs on glass"]</ref> as electricity conductor. In this case the final composite specification will be:
* '''Top Layer:'''...Standard glass
Line 23 ⟶ 24:
* '''Bottom layer:'''...Metallised bottom glass
==Thermoplastics used==
The transparent thermoplastic material will usually show a quite similar light refractive index compared to glass. Typical thermoplastics used in the glass industry to produce these type of security glazings will consist of Thermoplastic Polyurethane<ref>Bayer Inc., US2006135728 [http://v3.espacenet.com/publicationDetails/biblio?CC=JP&NR=2006169536A&KC=A&FT=D&date=20060629&DB=EPODOC&locale=en_EP "Thermoplastic polyurethane (TPU) having good adhesion to glass "]</ref> (TPU), Ethyl-Vinyl-Acetate<ref>Bridgestone Inc., DE4308885(B4) [http://v3.espacenet.com/publicationDetails/biblio?CC=DE&NR=4308885A1&KC=A1&FT=D&date=19930923&DB=EPODOC&locale=en_EP "Laminated glass with thermoset film of (meth)acrylate or hydrocarbon resin - containing EVA and organic peroxide for high impact strength, penetration resistance and transparency "]</ref> (EVA) or Poly-Vinyl-Butyral<ref>Solutia Inc., WO03057478 [http://v3.espacenet.com/publicationDetails/biblio?DB=EPODOC&adjacent=true&locale=en_EP&FT=D&date=20080320&CC=IL&NR=162701A&KC=A "GLASS LAMINATION PROCESS AND APPARATUS"]</ref> (PVB).
==Production==
The specification mentioned above will typically be produced in following steps:
# Vacuum sputtering of transparent conductive material on glass
Line 34 ⟶ 40:
# Mounting SMD LEDs on the glass by means of a pick & place process
# Lamination of the glasses according the specification mentioned above
Due to the fact, that most of the glass companies are not skilled to mount LEDs (Light Emitting Diodes) onto metallized glass, it makes sense to locate the LEDs on a separate transparent conductive polymeric interlayer<ref>D.

In other words, the remaining process for glass lamination units will consist of laminating together standard glass using 2 layers of thermoplastic interlayers to sandwich ready to use LED embedded films<ref>http://www.ledfilm.ch/ledfilm</ref>. The final specification will be:
