Insulated glass assembly with an internal lighting system
First Claim
1. An insulated glass assembly for use in a window comprising:
- first and second glass panes having facing generally parallel surfaces spaced a finite distance from each other,spacer means adhered to and extending around the periphery of the first and second glass panes for effecting a hermetically sealed air space between the first and second glass panes, andlighting means connectable to an electrical power source and disposed within the sealed air space for radiating light through at least one of the first and second glass panes with low thermal energy emission so as to prevent thermal expansion of the spacer means thereby maintaining the integrity of the hermetically sealed air space when connected to an electrical power source,the spacer means includes an elongated ribbon of sealant material having a first sealant end and a second sealant end, the ribbon of sealant adhering to the facing surface of the first and second glass panes with the first sealant end overlapping the second sealant end in adhering contact so as to hermetically seal the sealed air space between the first and second glass panes,the lighting means includes at least one light emitting diode lamp and wires for connecting the light emitting diode lamp to the electrical power source, the wires include a first end connected to the light emitting diode lamp within the sealed air space and a second end extending through the spacer means and interposed in adhesive engagement between the first end of the spacer means and second end of the spacer means.

Abstract
An insulated glass (IG) assembly for windows which includes an internal lighting system is disclosed. The IG assembly includes two or more panes of glass, a spacer and a strip of light emitting diodes (LEDs). The spacer separates glass panes and provides the hermetic seal for the IG assembly. The spacer extends around the periphery of the glass panes with a portion of its ends overlapping to form a sealed corner joint. The LED light strip includes a plurality of LED lamps connected in series by thin electrical contact wires fixed in a flexible nonconductive substrate. The LED strip is fixed to the spacer and extends around the periphery of the insulated glass unit. The lead wires from the LED light strip pass through the corner joint between the overlapped ends of the spacer. The LED light systems provide dependable illumination but emit relatively little thermal energy. Consequently, the LED light system maintains the thermal insulating properties of an insulated glass unit. The IG assembly can be incorporated into top and side lite windows or incorporated directly into doors themselves.
