Quantum dot light enhancement substrate and lighting device including same
摘要
說明書
In certain embodiments, a component comprises a substrate SUB comprising a material that is transparent to light within a predetermined range of wavelengths, a layered arrangement including two or more layers disposed over a predetermined region of a surface of the substrate SUB, wherein each of the layers comprises a color conversion material CCM comprising quantum dots capable of emitting light having a predetermined wavelength that is distinct from that emitted by quantum dots included in one or more of the other layers, and conductive material disposed over at least a portion of the layered arrangement, the conductive material being transparent to light within a second predetermined range of wavelengths, and one or more outcoupling features disposed on a surface of the substrate SUB opposite the color conversion material CCM.
In certain embodiments, a substrate SUB comprises a waveguide.
In certain embodiments, a substrate SUB is flexible.
In certain embodiments, a substrate SUB is rigid.
In certain embodiments, a component further includes a thin film interference filter between the substrate SUB and color conversion material CCM. Such filter can be useful to recycle unconverted light back into the color conversion material CCM and to remove undesired light from light emitted from the component or device including same.
In certain embodiments, a component further includes one or more outcoupling features disposed on a surface of the substrate SUB opposite the color conversion material CCM.
In certain embodiments, an outcoupling feature comprises a microlens.
In certain embodiments, an outcoupling feature comprises a micro-relief structure.
