  • Patent number: 10260710
    Abstract: A direct-type reflective diffusion lens and a lighting installation including the reflective diffusion lens. The reflective diffusion lens includes a first reflective surface concave and having a longitudinal cross-section with a parabola shape or normal distribution shape to totally reflect incident light, and a bottom surface comprising a light incident surface concave toward the first reflective surface. The reflective diffusion lens includes a second reflective surface having a longitudinal cross-section inclined by a first angle with respect to a central axis of the lens to totally reflect incident light and a refractive surface connecting the first reflective surface with the bottom surface. The refractive surface includes a first refractive surface having a longitudinal cross-section inclined by a second angle with respect to the central axis and a second refractive surface having a longitudinal cross-section inclined by a third angle with respect to the central axis.

  • Publication number: 20140307433
    Abstract: A reflective diffusion lens may include a bottom surface concave toward a reflective surface, a longitudinal cross section of the bottom surface being formed in a parabolic shape or normal distribution shape such that light incident upon the bottom surface is incident upon the reflective surface, and the reflective surface concave toward the bottom surface. The reflective surface may include a concave surface having a longitudinal cross section formed in a parabolic shape or normal distribution shape to totally reflect the light transmitted from the bottom surface and incident upon the reflective surface. A lighting installation may include at least one light source to emit light, a reflective diffusion lens to collect light emitted from the light source, and a reflective plate positioned at a lower portion of the light source and adapted to adjust a direction or amount of light reaching the reflective plate.

  • Patent number: 8379265
    Abstract: Disclosed are an image reading apparatus including a guiding unit disposed on a platen glass, and guiding a document transferred by a document transfer device to allow an image of a document to be read by an image sensor disposed at a stationary location. The guiding unit includes: a contacting surface that contacts the platen glass; a reading surface spaced apart upward from the contacting surface and having a flat reading portion corresponding to at least a reading reference location of the image sensor; an access guiding surface guiding the document to the reading surface, tilted downward toward the reading surface, and having an access terminal that is stepped with respect to the reading surface; and a discharge guiding surface guiding the document after the document has passed along the reading surface, and tilting upward from the reading surface without a step.

  • Patent number: 8368970
    Abstract: Disclosed herein is an image reader. The image reader can include a reading unit receiving light reflected from a document to thereby read image of the document and an automatic document feeder configured to supply the document to the reading unit. The automatic document feeder can include a channel defined within the automatic document feeder along which the document is supplied to the reading unit such that the reading unit is able to read the image of the document as the document moves along the channel. The channel can include a component having a surface tension that is less than or equal to about 40 dyne-per-centimeter.
