  • Publication number: 20090135626
    Abstract: Optical assembly includes a generally planar light output surface located on a first major plane, and a generally planar second surface located on a second major plane approximately parallel to the first major plane and superimposed thereon. Both the light output surface and the second surface have respective first and second patterns of well defined optical elements that are quite small in relation to the length and width of the optical assembly. The optical elements of the first pattern have an apex angle formed by a first sloped surface that is larger in an area closer to at least one light input edge of the optical assembly and smaller in another area further away from the light input edge.

  • Patent number: 7537370
    Abstract: Light emitting panel assemblies include an optical panel member having a pattern of light extracting deformities on or in one or both sides to cause light to be emitted in a predetermined output distribution. The pattern of light extracting deformities on or in one side may have two or more different types or shapes of deformities and at least one of the types or shapes may vary along the length or width of the panel member. Where the light extracting deformities are on or in both sides, at least some of the deformities on or in one side may be of a different type or shape or vary in a different way or manner than the deformities on or in the other side.

  • Patent number: 7524101
    Abstract: Edge lit light emitting assembly includes a panel member having a light input surface at one end of a greater width than thickness and an array of LEDs positioned in close proximity to the light input surface that emit light out of the side of the LEDs closest to the light input surface. At least one reflector around one or more of the LEDs collects light emitted by the LEDs and is shaped to reflect and focus the light at an acceptable angle for entering the light input surface, the focused light being shaped to have a greater cross-sectional width than height corresponding to the width and thickness of the light input surface.

  • Patent number: 7497599
    Abstract: The transreflectors may comprise a transparent substrate having reflective surfaces and other light transmissive surfaces for respectively reflecting and transmitting a greater portion of the light striking opposite sides of the substrate. Alternatively, the transreflectors may comprise two or more transparent substrates of different indices of refraction bonded together, with a pattern of optical deformities in the mating side of one of the substrates and an inverse pattern of optical deformities in the mating side of an other substrate in mating engagement with each other. The transreflectors are used in a transreflector system or display to transmit more of the light emitted by a backlight or other light source incident on one side of the transreflectors and reflect more of the light incident on the opposite side of the transreflectors. The transreflectors and backlight may be tuned to each other to enable the transreflectors to better transmit more of the light emitted by the backlight.

  • Publication number: 20090027918
    Abstract: Light emitting assembly includes at least one film, sheet, plate or substrate positioned between a light source and a display for redirecting at least some of the light emitted by the light source. One side of the film, sheet, plate or substrate may have a pattern of reflective or refractive surfaces or deformities and the other side may have corresponding or aligned optical deformities of well defined shape.

  • Patent number: 7434974
    Abstract: Light emitting panel assembly includes a light emitting panel member received in a cavity or recess in a tray or housing. The panel member has a pattern of light extracting deformities on or in at least one surface of the panel member to cause light received from at least one LED light source positioned near or against the light entrance surface of the panel member to be emitted from a light emitting surface of the panel member. The tray or housing acts as an end edge and/or side edge reflector for the panel member to reflect light that would otherwise exit the panel member through the end edge and/or side edge back into the panel member for causing additional light to be emitted from the panel member.
