Abstract: A backlight module and method of making the module uses a light panel and a light source device. The light source device includes a substrate on which light-emitting dies are mounted and an encapsulation plate with depressions, which is attached to the substrate such that the depressions are positioned over the light-emitting dies.

Abstract: A device and method for producing an enhanced color image of a scene of interest captures a grayscale image of the scene of interest using a flash of infrared light and a color image of the scene of interest without using any flash of infrared light. The grayscale information from the grayscale image and the visible color information from the color image are combined to produce the enhanced color image.

Abstract: A device and method for emitting output light utilizes multiple light sources to produce original light having different peak wavelengths. A first light source of the device is configured to generate first light having a peak wavelength in the blue wavelength range, while a second light source of the device is configured to generate second light having a peak wavelength in the red wavelength range. Some of the original light emitted from at least the first light source is converted into light having a peak wavelength longer than the peak wavelength of the original light using a photoluminescent material to produce the output light.

Abstract: A device and method for providing illuminating light utilizes quantum dots to convert at least some of the original light emitted from a light source of the device to longer wavelength light to change the color characteristics of the illuminating light. The quantum dots may be included in the light source, a light panel and/or an optional interface medium of the device.

Abstract: A device and method for emitting output light of a desired color utilizes green-emitting Thiogallate phosphor material and red-emitting SrCaS:Eu phosphor material to convert some of the original light emitted from a light source of the device to a longer wavelength light in order to produce the desired output light. The green-emitting Thiogallate phosphor material includes at least one of CaGa2S4:Ce phosphor and BaGa4S7:Eu phosphor. The device and method can be used to produce white light or other mixed color light using the light source, which may be a blue-green light emitting diode (LED) die.

Abstract: An apparatus, device and method for emitting output light utilizes Group IIB element Selenide-based phosphor material and/or Thiogallate-based phosphor material to convert at least some of the original light emitted from a light source of the device to different light to produce the output light, which may be white color light.
