    Abstract: Disclosed herein is an optical device having a light source, a viscoelastic lightguide and a retroreflective film suitable for retroreflecting light. Light from the light source enters the viscoelastic lightguide and is transported within the lightguide by total internal reflection. The transported light is extracted from the lightguide and retroreflected at a structured surface of the retroreflective film. The optical device may have a “front lit” or a “back lit” configuration depending on the relative positioning of the lightguide and the retroreflective film. The retroreflective film may include prismatic retroreflective sheeting, holographic film or film structured with diffraction gratings. The optical device may be used, for example, as a sign or marking, a license plate assembly, a tail light assembly for vehicles, a security laminate for protection of documents against tampering, or an illumination device.

    Abstract: A thermally conductive LED assembly is disclosed. The thermally conductive LED assembly includes an elongate conductor cable having a first conductor and a second conductor extending along a length of the elongate conductor cable and a thermally conducting and electrically insulating polymer layer disposed between first conductor and second conductor and a second electrically insulating polymer layer is disposed on the first conductor or second conductor. The electrically insulating polymer layer having a thermal impedance value in a range from 2.5 to 15 C°-cm2/W and a plurality of light emitting diodes are disposed along the length of the elongate conductor cable. Each light emitting diode is in electrical communication with the first conductor and the second conductor.

    Abstract: The present application is directed to an illumination device comprising a recycling cavity defined by recycling surfaces and a light emission surface; a light source within the cavity. A spectrum modifying layer is on a portion of the recycling surface, the spectrum modifying layer producing a spectral response different from the spectral response of the recycling surface. In some embodiments, the spectrum modifying layer shifts the spectral properties of the light being emitted from the light emission area from the spectral properties of the light source. In some embodiments, the spectrum modifying layer selectively absorbs a portion of light along the light source spectrum. In some embodiments, the spectrum modifying layer re-emits light at a wavelength longer than the wavelength it absorbed.
