Abstract: Provided are an integrated light guide plate and a lighting device including the same. Micro-sized engraved lenses are provided on one surface of a transparent substrate, coated with a reflector pattern having a visually unrecognizable size, such that dual-surface lighting is realized and the ratio between intensities of dual-surface lighting is adjusted without the addition of a reflector plate and a diffuser plate. The transparent substrate includes a first surface, a second surface, and third surfaces connecting the first surface and the second surface to each other, the second surface provided with a lens pattern including engraved lenses.

Abstract: A heat chamfering apparatus includes a heated body configured to peel an edge of a glass panel by applying thermal shock to the glass panel while being in contact with the edge of the glass panel and a heater heating the heated body. The heated body includes a heated region and a contact region in a longitudinal direction thereof, the heated region being heated by the heater, and the contact region being configured to be in contact with the glass panel. The cross-sectional area of the contact region is smaller than the cross-sectional area of the contact region. A heat chamfering method includes peeling an edge of a glass panel by applying thermal shock to the edge of the glass panel by moving a heated body heated by a heater relatively with respect to the glass panel along and in contact with the edge of the glass panel.

Abstract: Provided is a glass substrate heat chamfering method. An edge of a glass substrate (100) is chamfered by applying thermal shock to the edge of the glass substrate (100), thereby peeling a strip (100a) off from the edge of the glass substrate (100). The strip is cut at a predetermined point thereon before being broken due to the weight thereof. The strip (100a) is cut by applying at least one of heat and a laser beam to the predetermined point or by applying a flame (300a) of a torch (300) to the predetermined point. The application of the thermal shock includes brining a heating element (210) into contact with the edge of the glass substrate (100). In the chamfering, the heating element (210) is relatively moved along the edge of the glass substrate (100) while being brought into contact with the edge of the glass substrate (100).

Abstract: An optical structure for a light-emitting diode (LED) device, and an LED device for a lighting application including the same. The optical structure includes a light guide plate and a prism sheet, the light guide plate having first and second surfaces facing away from each other, the prism sheet is disposed on a peripheral portion of the first surface, and includes a plurality of prisms continuously arranged in one direction to form a pattern. At least some prisms have an asymmetrical structure in which light-refracting surfaces have different inclinations.

Abstract: A method of fabricating a glass panel includes forming a non-chamfered glass panel by cutting a glass sheet. The non-chamfered glass panel is formed by cutting the glass sheet along a first sideline segment, cutting the glass sheet along a corner line segment set connected to the first sideline segment, and cutting the glass sheet along a second sideline segment connected to the corner line segment set. An extension of the first sideline segment and an extension of the second sideline segment intersect each other at a first interior angle narrower than 230°. The first sideline segment and the corner line segment set are connected at an interior angle wider than the first interior angle and 180° but narrower than 230°. The corner line segment set and the second sideline segment are connected at an interior angle wider than the first interior angle and 180° but narrower than 230°.

Abstract: A method of fabricating a light guide plate (LGP), an LGP fabricated thereby, and an illumination device having the same. The method includes preparing an LGP and fabricating a light-scattering layer by printing a printing solution including light-scattering particles on an overall bottom surface of the LGP. The light-scattering layer may be fabricated by at least one of a first method of controlling the printing such that the density of the light-scattering particles gradually increases with increases in a distance from the light-emitting diode facing a side surface of the LGP and a second method of controlling the printing such that the thickness of the light-scattering layer gradually increases with increases in the distance from the light-emitting diode. A luminous point through can be prevented from being viewed by a front observer, a process can be simplified, and light distribution similar to Lambertian distribution can be obtained.
