The plurality of thermistors connected in parallel to each other being connected in series with the plurality of light-emitting elements connected in series to each other.

Vehicle lighting device and vehicle lamp

According to one embodiment, a vehicle lighting device includes a mounting portion that has a recessed portion; a plurality of bayonets that are provided on an outside surface of the mounting portion; a substrate that is provided on a bottom surface of the recessed portion; and a light emitting element that is provided on a side of the substrate opposite to a bottom surface side of the recessed portion. In a case where the vehicle lighting device is viewed from a light emitting side, at least one corner portion of the substrate overlaps with one of the plurality of bayonets.

A lighting device for a vehicle includes a plate-shaped flange; a placing portion provided on a first face of the flange; a light emitting module provided at an end face of the placing portion, and which includes a light emitting element; and a plurality of heat radiating fins formed in a plate shape, and which is provided on a second face of the flange on a side opposite to the first face. Also, the device includes a plurality of first protrusion portions provided on the second face of the flange in a line, in a direction intersecting a direction in which the plurality of heat radiating fins are aligned; and a second protrusion portion which is provided on the second face of the flange on a side opposite to the plurality of first protrusion portions, by interposing the plurality of heat radiating fins therebetween.

Lighting device for vehicle and lighting tool for vehicle

According to one embodiment, a lighting device for vehicles includes a mounting unit including a recessed portion which is provided on one face of a flange, and is open to an end face on a side opposite to a side of the flange; a substrate which is provided on a lower face side of the recessed portion, and includes a light emitting element on a face on the side opposite to a side of the flange; and a plurality of power feeding terminals which protrude from the lower face of the recessed portion, and are soldered to a wiring pattern provided on the substrate, in which a notch portion is provided at a portion on a side face of the recessed portion which faces the plurality of power feeding terminals.

Lighting device for vehicles and lighting tool for vehicles

A lighting device according to an embodiment includes a socket unit, a light emitting unit, and a lid unit. The light emitting unit is provided in an accommodation unit of the socket unit, and includes a light emitting element. The lid unit closes the accommodation unit of the socket unit, and is formed with an opening portion which causes light radiated from the light emitting element to pass through. An end face of the light emitting unit on the opening portion side overlaps with the opening portion in the thickness direction of the lid unit, and is located on the light emitting unit side rather than an end face of the lid unit on a side opposite to the light emitting unit side.

Lighting device and lighting device for vehicle

A lighting device for a moving body includes a substrate that has a base body having connection sections on a side surface and a wiring pattern provided on at least one main surface of the base body. The moving body further includes a light emitting element that is electrically connected to the wiring pattern, and an adhesive section that is provided between the base body and a body section. The connection sections are at least one of groove sections, concave sections, and convex sections, while the adhesive section covers at least a part of the plurality of connection sections.

Lighting device for moving body

A light emitting device according to an embodiment includes: a main body section; a light emitting section provided in the main body section and including a light emitting element; a cover provided on a side of the main body section where the light emitting section is provided; and an adhesive section provided between the main body section and the cover in a part of a region on the side of the main body section where the light emitting section is provided.

Light emitting device and vehicular lighting device

According to one embodiment, there is provided a luminaire including a light-emitting element and a cover provided on an irradiation side of the light-emitting element. The cover includes a first light transmitting section provided on the center side of the cover and a second light transmitting section provided at the peripheral edge of the first light transmitting section and having light transmittance higher than the light transmittance of the first light transmitting section.

Luminaire for interior lamp provided in automobile

A lighting device is provided that includes: a light emitting section that has a light emitting element and a switch for controlling a lighting state of the light emitting element; a housing that stores the light emitting section and has one end section which is open; a translucent cover that covers the opening of the housing; and a frame that is provided between the housing and the cover. The frame includes an edge section that presents a frame shape and a holding section having one end provided in the edge section and the other end protruding from the edge section. The holding section holds an operation section operating the switch and is exposed from the cover.

Light device with frame provided for holding switch operating section

A vehicle lighting device includes a light emitting unit, a holding unit, a light guide, a cover and an attachment unit. The light emitting unit has one or more light emitting elements. The holding unit holds the light emitting unit. The light guide guides light emitted from the light emitting unit and emits the light from a tip which is on a tip side opposite to a light emitting unit side. The cover has a first fixation unit to be fixed to the holding unit and a second fixation unit which has a diameter smaller than a diameter of the first fixation unit and internally fixes the light guide thereto in a state of exposing the tip. The attachment unit is formed in the second fixation unit in a shape attachable to a reflector.

Vehicle lighting device

A lighting device controls power to a discharge lamp according to the temperature detected by a lamp sensor, which detects temperature around the discharge lamp. The discharge lamp has an arc tube and an outer bulb between which an airtight space is defined. Therefore, the lamp can be actuated without reduction in luminosity even at low temperatures. Also, the lamp luminosity rises quickly.
