  • Patent number: 10634294
    Abstract: A light source is realized in a wall portion and a base portion forming a flexible structure, the wall portion having a plurality of inward facing LEDs, a bottom edge of the wall portion being adjacent to an edge of the wide portion. The resulting well is subsequently filled with a material to form an optical cavity, the height of the resultant optical cavity being matching a top edge of the wall portion. The top surface of the optical cavity is spin coated with a thin layer of quantum dots which serve to shift a wavelength of light emitted from the LEDs. Finally, a protective layer is applied to fix and protect the thin layer of quantum dots. Thus, a light source is realized which can reliably provide light at a specific wavelength defined by the interaction between the LEDs and quantum dots.
