  • Patent number: 10333036
    Abstract: A method is provided for fabricating an emissive display color conversion film. An emissive substrate top surface is conformally coated with an optically transparent carrier film, covering an array of emissive elements. A suspension, including a fluid and a color conversion material (e.g., QDs), is then selectively deposited in absorption regions overlying the emissive elements, for example, using inkjet patterning. After the suspension is absorbed into the absorption regions, the fluid is removed from the suspension, leaving the color conversion material in the absorption regions, and forming the color conversion film. The removal of the fluid encapsulates the color conversion material in the absorption regions. Typically, the conformal coating is thick enough to form a planar top surface. The conformally coating of carrier film may also act to encapsulate both properly aligned emissive elements, as well as misaligned emissive elements that may be located on the emissive substrate top surface.

The transparent conductor layer may be a wire mesh with openings. A liquid or paste polymer layer is then deposited over the transparent conductor layer and directly contacts the first dielectric layer. The indices of refraction of both layers are similar to reduce TIR. The top surface of the polymer layer is then molded to contain light extraction features to reduce waveguiding in the light sheet. In another embodiment, the substrate surface is the light exit surface that has the light extraction features.

  • Patent number: 9200765
    Abstract: A light source, for example a light emitting diode, can emit light and have an associated optical axis. The source can be deployed in applications where it is desirable to have illumination biased laterally relative to the optical axis, such as in a street luminaire where directing light towards the street is beneficial. The source can be coupled to an optic that comprises a cavity. A first region of the optic can receive light from the source and emit light towards the area to be illuminated. A second region of the optic can comprise two reflective surfaces. The first reflective surface can receive light from the source and reflect the received light towards the second reflective surface. The two reflective surfaces can be used to direct light away from one side of the optic.

  • Patent number: 9182098
    Abstract: A device for scattering light emitted from at least one light source includes, among other things, a light coupler configured for placement adjacent to the light source. The light coupler includes a first region proximal the light source where the first region has a first index of refraction and a second region abutting the first region to define a boundary therebetween. Being distal to the light source, the second region has a second index of refraction that is greater than the first index of refraction. Light emitted from the light source is scattered as a result of travelling through the first region and the second region.
