  • Patent number: 9736900
    Abstract: A tunable light generating assembly uses ultraviolet and blue light emitting diodes to pump red and green quantum dots in a quantum dot layer to generate white light. A dielectric mirror substrate having a wavelength selective reflectance is configured to reflect ultraviolet wavelengths, and to pass blue and longer wavelengths. The portion of the ultraviolet light that is not absorbed in the quantum dot layer is reflected rather than transmitted, where it has another chance to be absorbed in the quantum dot layer, thereby increasing the overall conversion efficiency. The increased energy associated with the ultraviolet light further results in greater conversion efficiency in the quantum dot layer. The ultraviolet and blue LEDs may be driven by an electronic circuit that varies the amount of power applied to each LED to control the brightness and color balance of the generated white light.

  • Patent number: 9535282
    Abstract: A system and method are disclosed employing a dielectric mirror layer, highly reflective at wavelengths below a cut off but highly transparent at wavelengths above the cut off, is placed within a display assembly. This dielectric mirror layer creates a very efficient reflecting cavity for a portion of a Light Emitting Diode (LED) pumping spectrum. Accurate dielectric filter tuning allows an increased portion of the pumping spectrum to be converted to desired wavelength spectrum and also raise the luminance ratio of the display to a useful value for display applications. Variable and active tuning of the cut off wavelength value functions to optimize system performance.

  • Patent number: 8475028
    Abstract: A light emitting diode (LED) night vision imaging system (NVIS) lens apparatus for use in filtering of a plurality of night-mode LEDs is provided. The lens apparatus includes an optical carrier material having a plurality of apertures disposed and arranged such that, when the lens apparatus is coupled to an LED backlight, each of the plurality of apertures allows light from a corresponding day-mode LED to be transmitted therethrough without filtering. The lens apparatus also includes filter material coupled to and supported by the optical carrier material. The filter material is disposed and arranged on the optical carrier material such that, when the lens apparatus is coupled to the LED backlight, light from each of a plurality of night-mode LEDs is filtered by the filter material. Backlight assemblies and displays are also provided.

  • Patent number: 7307805
    Abstract: A flexible filter for use in filtering wavelengths of light that interfere with night vision awareness systems is disclosed. A filtering material is applied to a first flexible film in a substantially liquid form and is cured thereto using ultraviolet light. The filtering material filters wavelengths of light between about 610 and 930 nanometers when cured. A second flexible film is temporarily held in place by a support member. The second flexible film is applied to the cured filtering material and is fused thereto using a combination of increased temperature and pressure for a predetermined time. The first and second flexible films are made of polyurethane.

  • Patent number: 7081991
    Abstract: A display includes a light source. The display also includes a filter positioned to receive light from the light source. The filter is a dye-based filter and attenuates light in the infrared range. The filter can be configured to have a very sharp spectral cutoff. The filter can be an NVIS filter. The display can be utilized in an avionic display system with night vision equipment. The filter can include a host polymer doped with a dye including cobalt or nickel.

  • Patent number: 7002546
    Abstract: A variably controlled LCD backlight is disclosed. The backlight includes a first light source that emits light within a first spectral power distribution and has a first radiant power output. A second light source emits light within a second spectral power distribution and has a second radiant power output. A detector detects the first and second radiant power outputs. A processor is connected to the detector and calculates chromaticity and luminance values of the emitted light based on the first and second radiant power outputs. The processor compares the calculated chromaticity and luminance values with desired chromaticity and luminance values, respectively. A controller is operationally connected to the processor and adjusts one or more of the first radiant power output and the second radiant power output in response to a difference between the calculated chromaticity and luminance values and the desired chromaticity and luminance values.

  • Patent number: 5335070
    Abstract: A new and improved laser light beam homogenizer for transforming a laser beam with spatially inhomogeneous intensity into a beam with a more nearly spatially uniform intensity pattern is presented. The light beam is diverged by a lens and presented to an integrator. The integrator transforms the beam into a beam with a more uniform illumination. The uniform illumination beam is then impinged on control optics to limit the divergence of the uniform beam and control higher order distortion in the system. This beam may then be illuminated at a predetermined distance by a projecting optic lens. The laser light beam homogenizer of this invention is particularly well suited for use in an imaging lidar system.
