Insulated glass units incorporating emitters, and/or methods of making the same

1. An insulated glass unit, comprising:

first and second substantially parallel, spaced apart glass substrates, the first and second glass substrates defining a gap therebetween;

an edge seal provided around a periphery of the first and second substrates;

an emitter disposed in the gap;

a conductive interface formed in the edge seal, the conductive interface supporting an electrical connection between the emitter and a power source located external to the insulated glass unit; and

wherein the edge seal is a hermetic seal and wherein the gap includes argon, krypton, and/or xenon gas.

2. The insulated glass unit of claim 1 , wherein the edge seal is an hermetic seal and wherein the emitter is disposed, directly or indirectly, on the first glass substrate without any intervening substrates therebetween.

3. The insulated glass unit of claim 1 , wherein the emitter is an organic light emitting diode.

4. The insulated glass unit of claim 1 , further comprising a wire harness provided in the conductive interface of the edge seal, the wire harness supporting a wire connected to the power source and to a lead connected to the emitter.

5. The insulated glass unit of claim 1 , wherein the insulated glass unit is a window for a building.

6. An insulated glass unit, comprising:

first and second substantially parallel, spaced apart glass substrates, the first and second glass substrates defining a first gap therebetween;

an edge seal provided around a periphery of the first and second substrates;

an emitter;

a conductive interface formed in the edge seal, the conductive interface supporting an electrical connection between the emitter and a power source located external to the insulated glass unit;

third and fourth substantially parallel, spaced apart substrates, the third and fourth substrates defining a second gap therebetween,

wherein the emitter is disposed in the second gap, and

wherein the third and fourth substrates are disposed in the first gap between the first and second glass substrates.

7. The insulated glass unit of claim 6 , further comprising a second edge seal hermetically sealing together the third and fourth substrates.

8. The insulated glass unit of claim 7 , wherein the first gap includes a first type of gas and the second gap includes a second type of gas.

9. The insulated glass unit of claim 6 , wherein an edge seal between the third and fourth substrates is an hermetic seal and wherein the first gap includes argon, krypton, and/or xenon gas.

10. The insulated glass unit of claim 6 , wherein the insulated glass unit is a window for a building.

11. A method of making an insulated glass unit, the method comprising:

providing a first glass substrate;

providing a second glass substrate;

orienting the first and second glass substrates in substantially parallel, spaced apart relation to one another and defining a gap therebetween;

providing an edge seal around a periphery of the first and second substrates;

disposing an emitter, directly or indirectly, on the first and/or second substrate,

wherein a conductive interface is located in the edge seal, the conductive interface supporting an electrical connection between the emitter and a power source located external to the insulated glass unit,

wherein the emitter is sandwiched between third and fourth substantially parallel, spaced apart substrates, the third and fourth substrates defining a second gap therebetween, and

wherein the third and fourth substrates are disposed in the gap between the first and second glass substrates.

12. The method of claim 11 , further comprising providing a wire harness in the conductive interface of the edge seal, the wire harness supporting a wire connected to the power source and to a lead connected to the emitter, the wire harness being at least partially filled so the edge seal is an hermetic seal.
