Certain example embodiments of this invention relate to techniques for improving the performance of Lambertian and non-Lambertian light sources. In certain example embodiments, this is accomplished by (1) providing an organic-inorganic hybrid material on LEDs (which in certain example embodiments may be a high index of refraction material), (2) enhancing the light scattering ability of the LEDs (e.g., by fractal embossing, patterning, or the like, and/or by providing randomly dispersed elements thereon), and/or (3) improving performance through advanced cooling techniques. In certain example instances, performance enhancements may include, for example, better color production (e.g., in terms of a high CRI), better light production (e.g., in terms of lumens and non-Lambertian lighting), higher internal and/or external efficiency, etc.

1. A method of making a light source comprising a coated article including a substrate supporting a coating, the method comprising: providing a titanium-based precursor;providing a chelate;reacting the titanium-based precursor with the chelate to form a chelated titanium-inclusive substance;providing an organic resin material;cross-linking the chelated titanium-inclusive substance with the organic resin material to form an organic-inorganic hybrid solution; anddisposing the organic-inorganic hybrid solution on the substrate in forming the coating, wherein the coating has an index of refraction of at least about 1.8 and is substantially transparent. 2. The method of claim 1, wherein said disposing involves slot die coating the organic-inorganic hybrid solution. 3. The method of claim 2, further comprising drying and/or curing the organic-inorganic hybrid solution in forming the coating. 4. The method of claim 1, further comprising: drying the organic-inorganic hybrid solution at a temperature of less than about 250 degrees C.;curing the organic-inorganic hybrid solution at a temperature of at least about 300 degrees C. 5. The method of claim 1, further comprising introducing the organic-inorganic hybrid solution into a laminable medium, the laminable medium being disposed on the substrate during said disposing. 6. The method of claim 5, wherein said disposing is practiced by extruding the laminable medium on the substrate. 7. The method of claim 5, wherein the laminable medium is EVA. 8. The method of claim 5, wherein the laminable medium is silicone. 9. The method of claim 1, wherein the titanium-based precursor is titanium alkoxide. 10.
