Certain example embodiments of this invention relate to heatable glass substrates that may be used in connection with lighting applications, and/or methods of making the same. In certain example embodiments, a glass substrate supports an antireflective (AR) coating on a first major surface thereof, and a conductive coating on a second, opposite major surface thereof. Bus bars connect the conductive coating to a power source in certain example embodiments. The substrate may be heat treated (e.g., heat strengthened and/or thermally tempered), with one or both coatings thereon. The heatable glass substrate thus may help provide a chemical and/or environmental barrier for the luminaire or lighting system disposed behind it. In addition, or in the alternative, the heatable glass substrate may help reduce the amount of moisture (e.g., snow, rain, ice, fog, etc.) that otherwise could accumulate on the luminaire or lighting system.

1. A lens for a lighting system, comprising: a glass substrate supporting an antireflective coating and a transparent conductive coating on first and second major surfaces thereof, respectively; andat least one bus bar in electrical communication with the transparent conductive coating, the at least one bus bar being configured to convey voltage to the transparent conductive coating to cause the transparent conductive coating to heat,wherein the substrate is to be heat treated together with the antireflective and transparent conductive coatings thereon; andwherein the transparent conductive coating comprises a layer comprising a transparent conductive oxide (TCO) sandwiched between first and second layers comprising silicon oxynitride. 2. The lens of claim 1, wherein the antireflective coating provides a visible transmission increase of 4% points, compared to a situation where no antireflective coating is provided. 3. The lens of claim 1, wherein post heat treatment, the lens has a visible transmission of at least 87%. 4. The lens of claim 1, wherein the TCO comprises indium tin oxide. 5. A lighting system, comprising: a lens comprising: a glass substrate supporting an antireflective coating and a transparent conductive coating on first and second major surfaces thereof, respectively; and at least one bus bar in electrical communication with the transparent conductive coating, the at least one bus bar being configured to convey voltage to the transparent conductive coating from an external power source to, in turn, cause the transparent conductive coating to heat;wherein the lens is interposed between one or more solid state lights and a viewer of the lighting system. 6. The lighting system of claim 5, wherein the one or more solid state lights comprise an array of organic and/or inorganic light emitting diodes. 7. The lighting system of claim 5, wherein the lens is spaced apart from the one or more solid state lights. 8. A lens for a lighting system, comprising: a glass substrate supporting an antireflective coating and a transparent conductive coating on first and second major surfaces thereof, respectively; andat least one bus bar in electrical communication with the transparent conductive coating, the at least one bus bar being configured to convey voltage to the transparent conductive coating to cause the transparent conductive coating to heat,wherein the substrate is configured to be heat treated together with the antireflective and transparent conductive coatings thereon; andwherein the transparent conductive coating comprises a layer comprising a transparent conductive oxide (TCO) layer comprising ITO sandwiched between first and second dielectric layers comprising silicon and nitrogen, wherein the TCO layer comprising ITO has a thickness of from 100-170 nm and a sheet resistance from 10-30 ohms/square. 9. The lens of claim 8, wherein the first and second dielectric layers each have refractive indexes of 1.7+/−0.2 at 550 nm and an extinction coefficient k of <0.01 at 550 nm, and wherein the layer comprising the TCO has a refractive index of 1.9+/−0.1 at 550 nm. 10. The lens of claim 8, wherein the antireflective coating provides a visible transmission increase of 4% points, compared to a situation where no antireflective coating is provided. 11. The lens of claim 8, wherein post heat treatment, the lens has a visible transmission of at least 87%. 12. A lighting system including the lens of claim 8, wherein the lens is interposed between one or more solid state lights and a viewer of the lighting system. 13. The lighting system of claim 12, wherein the lens is spaced apart from the one or more solid state lights.
