A projector includes a light source to emit light, a design plate including a design for projecting, a first lens part including a condenser lens to condense light emitted from the light source and sends to the design plate, and a second lens part including a projection lens to project the design of the design plate. The first lens part and the second lens part sandwich and fix the design plate to seal the design plate inside.

A lighting device includes a first light source portion, a light guide that includes a light guide body with an elongated shape, guides light incident from the first light source portion in a longitudinal direction of the elongated shape, and emits a first light including the guided light to illuminate an illuminated object, and a second light source portion that emits a second light to illuminate the illuminated object. The second light source portion is provided independently of the first light source portion and the light guide.

Lighting device

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

A light guide includes a rod-shaped first light guide portion including a prism surface including a prism to reflect internally propagating light and output the light to an outside along a lengthwise direction thereof, a rod-shaped second light guide portion including a light intake portion to take in light from a light source, and a rod-shaped intermediate light guide portion between the first light guide portion and the second light guide portion provided such that side surfaces thereof are connected to side surfaces of the first light guide portion and the second light guide portion. A thickness of the intermediate light guide portion is smaller than a thickness of the first light guide portion and a thickness of the second light guide portion. A side surface of the intermediate light guide portion on a side of the prism surface is continuous with the prism surface in a same plane.

An illumination apparatus includes: a light source including an LED and a lens; an illuminated body; and a cover, wherein: the light source is arranged inside the cover; the light from the light source passes between the edge of the cover and the illuminated body; the front edge of the cover defines the illumination range of the light from the light source with respect to the illuminated body; and the light transmittance of such portion of the lens as is near to the illuminated body is higher than that of the remaining portions.

Illumination apparatus

Disclosed is a lighting apparatus for power-receiving connector. The power-receiving connector includes a power-receiving accommodation chamber, and a power-receiving unit. The lighting apparatus is disposed on an accommodation bottom face in the power-receiving accommodation chamber, and includes a lighting cover. The lighting cover has a cover top face opposing the accommodation bottom face, and a cover side face disposed between the accommodation bottom face and the cover top face and inclining so as to overhang from the cover top face toward the accommodation bottom face. The cover side face includes a first emission portion directed to a vehicular lower side, and a second emission portion directed to a vehicular lateral side. A first elevation angle exhibited by the first emission portion to the accommodation bottom face is smaller than a second elevation angle exhibited by the second emission portion to the accommodation bottom face.

Light apparatus for power-receiving connector

An illumination apparatus includes a light source that emits light, a light guide member that has a base end surface onto which the light emitted from the light source is incident and a tip surface which is an opposite end surface to the base end surface, and guides the light from the base end surface towards the tip surface, and an attachment member that has a light shield property and an opening corresponding to a shape of the light guide member and accommodates the light guide member in the opening. The light guide member is curved so that a distance between the light guide member and the opening is gradually increased towards the tip surface-side in a longitudinal direction of the light guide member.
