A backlight unit of a curved display device to irradiate a curved display panel with light comprises: a light source configured to emit light to the display panel; and a back plate including a plurality of planar sections, each having a predetermined width, arranged in a circumferential direction of the display panel on a concentric circle, the center point of which coincides with the center point of a virtual circle defined by the curved display panel, the planar sections of the back plate being bent relative to each other into a curved form such that the light source is installed to the respective bent sections of the bent curved back plate.

Provided is an optical sensing member, comprising a light guide plate 102 which propagates light from a light source unit 108, detecting units 104, 106 which detect scattered light from the light guide plate 102 being touched, an optical member which guides the scattered light to the detecting units, and a primary control unit 118 which computes the touch location upon the light guide plate 102 on the basis of information relating to the detected light. The optical member has arc-shaped curved surfaces formed on the end parts which face each of the detecting units. Each of the detecting units outputs, as the information relating to the light which is detected by the detecting units, location information corresponding to the angle of entry to the detecting units of the light which is radiated from the facing arc-shaped curved surfaces. It is thus possible to clarify contours of the light which is detected by the detecting units, and to improve the precision of the detection of the touch location.

An optical device includes a light guide plate configured to guide light within a plane parallel to an emission surface, and a plurality of light focusing portions to which the light guide plate guides directional light. Each of the plurality of light focusing portions is provided with an optical surface configured to create from the directional light incident thereon emission light in a direction substantially converging on a single convergence point or convergence line in a space or to create emission light that substantially diverges from a single convergence point of convergence line in a space and exits from the emission surface. The plurality of light focusing portions are provided near the emission surface of the light guide plate, and each of the plurality of light focusing portions is formed along a predetermined line within a plane parallel to the emission surface.

Vehicle light comprising a container body that houses at least one light source, a lenticular body, a light guide, the light source, so as to receive the light beam and transmit it to a light outlet wall. The light guide comprises a body that defines the propagation direction of the light beam inside the body by total internal reflection. The body has a first groove, comprising a plurality of first holes, defining cylindrical or spherical optics that produce a scattering of said light rays (Ri) towards the light outlet wall so as to emit a light beam with opalescent effect. The first holes are adjacent to each other without interruption and are blind with respect to a thickness of the body of the light guide, penetrating from a first face of the body for a first depth less than said thickness.

A light source module and a cooking appliance including the same may include a light source emitting light toward a glass top plate, a light source guide to accommodate the light source, including a light transmitting path formed in the light source guide, and limit a light irradiation region so as to guide light emitted from the light source to a light display region of the glass to plate through the light transmitting path, and an attachment bracket provided between the light source guide and the glass top plate, the attachment bracket having an optical emission path to allow light to pass from the light transmitting path and the light display region.

A flexible inside corner trim piece is formed with concave depressions at hinge portions where wings attach to the body. The trim piece can be formed such that wings and a top cap lay flat in plane perpendicular to body or wings and top cap curve at an angle. Hinge portions can be narrow or wide and symmetrical or asymmetrical. The trim piece can be dyed, paintable, or present another decorative surface. The trim piece can include embedded lighting.
