  • Patent number: 10386566
    Abstract: A vehicle lighting device includes a storage member with an opening for receiving an object and a support bottom portion; a light source; and a light guide member including an incident portion positioned on an outer peripheral portion side of the light guide member, a light emission surface arranged along an edge of the opening, and a shielding wall positioned between the outer peripheral portion and the inner peripheral portion and extending along the receiving opening. The light guide member further includes a portion where a distance between the inner peripheral portion and the outer peripheral portion is gradually reduced as it moves in from the incident portion.

  • Patent number: 10351056
    Abstract: An illumination device includes a light-guide member having an annular shape provided with an incidence portion of a light in one portion, and illuminating the entirety by propagating an incident light; and a diffusion cover disposed on a side opposite to a light source relative to the incidence portion by interposing the light-guide member therebetween, and diffusing a light generated from the light-guide member. The diffusion cover includes a plate-shaped base portion covering the incidence portion side in the light-guide member, and a circular portion covering the remaining portions of the light-guide member by integrating an outer peripheral portion into the plate-shaped base portion.

  • Patent number: 10071682
    Abstract: An illumination device includes a housing portion having an opening for inserting an object to be housed, and a bottom face capable of supporting the object to be housed; a light source; and a light-guide plate having a light-emitting face and guiding a light of the light source to emit light from the light-emitting face. The light-guide plate is disposed between the opening of the housing portion and the bottom face, and at least one portion of the light-emitting face of the light-guide plate is arranged to form an acute angle with respect to the bottom face so as to directly irradiate the bottom face from a diagonal direction.

  • Publication number: 20180172896
    Abstract: A lighting device includes a storage member provided with a receiving opening for an object to be stored, and a support bottom portion for supporting the received object to be stored; a light source; and a loop-shaped light guide member including an incident portion for a light from the light source and a light emission surface formed along an edge of the receiving opening. The incident portion is positioned on an outer peripheral portion side of the light guide member, and a shielding wall along the receiving opening is positioned between the outer peripheral portion and the inner peripheral portion. Also, the light guide member includes a gradually-reduced portion reducing a distance between the inner peripheral portion and the outer peripheral portion as leaving from the incident portion.
