A lighting device includes a light source unit that outputs light, an elongated light guide including a first end surface on which the light is incident, a second end surface located opposite to the first end surface, an emitting surface, and at least one held portion provided on at least one of the longitudinal side surfaces different from the emitting surface, the light guide guiding the light from the first end surface to the second end surface, and a housing including an attachment portion to which the light source unit is attached, a housing portion that is open at an end portion on the attachment portion side and includes a housing recess to house the light guide and an exposure opening exposing the emitting surface, and a holding portion that holds the light guide in the housing recess by sandwiching the at least one held portion.

Lighting device with elongated light guide, housing and attachments thereof

Cup holder light lens

A cup holder includes first and second concave housing portions to house a cup, and a light source to illuminate a bottom portion of the first housing portion and a bottom portion of the second housing portion. The light source is placed between the first housing portion and the second housing portion and at a higher position than the bottom portion of the first housing portion and the bottom portion of the second housing portion. The cup holder is configured such that light emitted from the light source provides an illuminance of the bottom portion of the first housing portion that is more than an illuminance of the bottom portion of the second housing portion.

Cup holder

A cup holder includes a main body that includes a recess-shaped cup housing portion for housing a cup, a light source arranged on a back surface of the main body and located under the cup housing portion, and a plate-shaped light guide lens placed on a bottom surface of the cup housing portion of the main body. The main body includes a first hole and a second hole on the bottom surface of the cup housing portion. The second hole is arranged to guide light emitted from the light source to the light guide lens, and the first hole is arranged to drain liquid inside the cup housing portion.

An illuminating device includes a light source having a light-source optical axis, a lens that is located substantially parallel to the light-source optical axis such that a surface of the lens faces the light-source optical axis, the lens extending to a position rearward of the light source in a direction of the light-source optical axis, and a light reflecting portion located so as to be opposed to a front side of the light source, the light reflecting portion being adapted to reflect emitted light of the light source obliquely rearward of the light source, and reflect the emitted light toward the lens.

Illuminating device

A lighting member includes a light guiding element, and a housing including a cover element and a light-guiding-element attachment claw. The cover element is formed as a frame shape, is capable of deforming elastically, and covers an outer peripheral face of the light guiding element over the entire circumference. The light-guiding-element attachment claw is disposed integrally with the cover element, and protrudes diametrically toward an inner side beyond the outer peripheral face of the light guiding element. The housing has an inner peripheral face facing the outer peripheral face of the light guiding element, and further includes a larger-clearance portion and smaller-clearance portion. The larger-clearance portion provides a larger clearance between the inner peripheral face of the cover element and the outer peripheral face of the light guiding element than does the smaller-clearance portion between them.

Lighting member

The present invention provides a linear lighting device which includes an elongated light guide, a light source disposed at an end in a longitudinal direction of the light guide, and a case accommodating the light guide and the light source. In the linear lighting device, the light guide has a plurality of grooves arranged in the longitudinal direction of the light guide, and has a stepped cutout at the other end on an opposite side from the end, and a protruding portion protruding into the cutout is formed on an inner surface of the case which faces the cutout.

Linear lighting device

A charging device charges an in-vehicle battery for an electric vehicle by a power supply fed from an attachment plug extending from an external power supply. The charging device includes: a charging inlet; a housing recess formed within the charging inlet; a charging connector disposed within the housing recess; and an illumination light source embedded in an upper peripheral wall of the housing recess. The illumination light source emits light downward, and an optical axis thereof is positioned closer to an opening of the housing recess than a front surface of the charging connector. A first irradiation light emitted toward the opening of the housing recess than the optical axis is emitted obliquely downward from the charging inlet. A second irradiation light emitted toward a bottom of the housing recess than the optical axis is emitted to the charging connector.

Light guide body for light emitting diode lamp

The present invention provides a vehicle room light apparatus which is small in size and achieves high heat dissipation. The vehicle room light apparatus includes a light source; a switch; and a case including a front surface as a designed surface and a back surface. The back surface having a first region on which the light source and the switch are arranged in line, a second region which has a space extending along the first region and an opening continuing to the space, a partition wall which separates the first and the second regions.

A light-emitting elementhas a rod-shaped light-emitting element, an LED lamp, and a lensfor converging light from the LED lamp to an end face of the rod-shaped light-emitting element. The lenshas a scattering area around the centerline of an extremity thereof, and the scattering area scatters light in proximity to the centerline, thereby irradiating an inner peripheral surface of the rod-shaped light-emitting elementwith the light.

Light-emitting device, and lens used in the same

An LED lamp system includes a light emitting diode (LED) lamp, a printed circuit board on which the LED lamp is mounted, a connection terminal including a soldering part inserted and soldered to the printed circuit board, a body part extending parallel to the printed circuit board, and a branch part extending from the body part in a predetermined direction, a case to which the printed circuit board is fixed, the case including a holding portion for holding the branch part of the connection terminal, and a cover for enclosing the LED lamp and the printed circuit board in association with the case.
