  • Patent number: 9791128
    Abstract: The present disclosure describes light delivery and distribution components of a ducted lighting system having a cross-section that includes at least one curved portion and a light source. The delivery and distribution system (that is, light duct and light duct extractor) can function effectively with any light source that is capable of delivering light which is substantially collimated about the longitudinal axis of the light duct, and which is also preferably substantially uniform over the inlet of the light duct.

  • Publication number: 20170038527
    Abstract: The present disclosure describes light delivery and distribution components of a ducted lighting system having a cross-section that includes at least one curved portion and a remote light source. The delivery and distribution system (i.e., light duct and light duct extractor) can function effectively with any light source that is capable of delivering light which is substantially collimated about the longitudinal axis of the light duct, and which is also preferably substantially uniform over the inlet of the light duct. The light delivery and distribution system can further function as a structural element that adjoins at least two walls of an illuminated enclosure or supports the shelves of illuminated shelving, joining the unit together.

  • Publication number: 20160018592
    Abstract: The present disclosure describes light delivery and distribution components of a ducted lighting system having a cross-section that includes at least one curved portion and a remote light source. The delivery and distribution system (i.e., light duct and light duct extractor) can function effectively with any light source (480) that is capable of delivering light which is substantially collimated about the longitudinal axis (405) of the light duct (410), and which is also preferably substantially uniform over the inlet of the light duct. A turning film (450) comprising parallel ridged microstructures intercepts and redirects light rays exiting the light output region. The light duct (410) is hollow and comprises a light transmissive region (430) which may vary in size along the longitudinal axis (405).

  • Patent number: 8976327
    Abstract: Optical shutter (50), e.g. fort-stereoscopic shutter glasses, is disclosed. The optical shutter includes a light source, e.g. LCD, CRT or plasma display, that emits polarized light (12) that has a first polarization state, a first polymeric substrate (100) that receives the polarized light and transmits the polarized light without substantially changing the first polarization state of the polarized light, a second polymeric substrate (107) that faces the first polymeric substrate, and an optical stack (60) that is disposed between the first and second polymeric substrates. The optical stack includes first and second electrically conductive layers (101, 102), first and second oriented chromonics alignment layer (103, 106), and an oriented liquid crystal layer (105).

  • Patent number: 8928745
    Abstract: 3D stereoscopic viewing enabled by the use of a fast switching speed LCD panel, dynamic backlight, and low cost glasses. The system utilizes an LCD panel with an LED backlight and wavelength selective glasses to isolate each channel by color. The system is based on alternating left and right image frames on an LCD panel. The left and right frames are illuminated by two slightly different red-green-blue light sources that are synchronized sequentially. The light sources are designed to emit light of different spectral composition. The viewer wears glasses where the left lens or filter passes only the spectrum of light used for the left channel of data, and the right lens or filter passes only the spectrum of light used for the right channel of data.

  • Patent number: 8192048
    Abstract: The present disclosure relates to illumination or lighting assemblies and systems that provide illumination using LEDs. In one aspect, the present disclosure provides a lighting assembly, comprising: multiple light emitting diodes that emit light; an optical system that directs the light emitted by the light emitting diodes, the optical system positioned adjacent to light emitting diodes; and a cooling fin including a two-phase cooling system, the cooling fin positioned adjacent to the light emitting diodes such that the two-phase cooling system removes heat from the light emitting diodes. In another aspect, the present disclosure provides a lighting system including multiple lighting assemblies.

  • Publication number: 20100165001
    Abstract: A backlight includes n1, n2, and n3 colored LED light sources of a first, second, and third (non-white) color respectively, and a drive circuit connected to these sources. The drive circuit is configured to drive each of the first, second, and third light sources within a specified percentage, such as 10%, of their respective maximum drive characteristics, and the numbers n1, n2, and n3 are selected so that light from the energized first, second, and third LED light sources, when combined, is substantially white. In some cases, the backlight also includes a number n4 of white LED sources, and the colored LED sources may or may not be driven within 10% of their maximum ratings. The number n4 of white sources is selected to increase the brightness of the backlight while maintaining the color gamut of the backlight output within a specified percentage, such as 10%, of a desired specification.

  • Patent number: 6331438
    Abstract: Optical sensor, probe and array devices for detecting chemical biological, and physical analytes. The devices include an analyte-sensitive layer optically coupled to a thin film electroluminescent layer which activates the analyte-sensitive layer to provide an optical response. The optical response varies depending upon the presence of an analyte and is detected by a photodetector and analyzed to determine the properties of the analyte.
