Abstract: A lighting unit includes a housing, a first cover, and a second cover. The housing is configured to house a light source and a circuit body constituting a circuit between the light source and an outside of the housing. The first cover is mountable to the housing and configured to emit light from the light source to the outside of the housing. The second cover is mountable to the housing and includes a cover-side attachment portion attachable to an attachment hole of a lighting attachment member. The second cover is configured to emit the light from the light source to the outside of the housing through the attachment hole. The first cover and the second cover are selectively mountable to the housing.

Abstract: A bulb socket and a lighting system, which can reduce components and dimensions and improve a force for holding a bulb, are provided. A housing has an insertion hole including an opening for receiving a base portion of a bulb, and a plurality of projection portions projecting from a deep side wall of the insertion hole toward an opening side. The projection portions are opposed to each other so that the base portion is sandwiched therebetween. A distance between the projection portions is formed smaller than a cross-sectional dimension of the base portion. When the base portion is inserted into the insertion hole, the projection portions are elastically deformed away from each other, and contacts slidingly a surface of the base portion. The base portion is sandwiched by a biasing force of the elastically deformed projection portions in a biasing state, and thereby the bulb is held.

Abstract: There is provided an interior illumination lamp for a vehicle. In the interior illumination lamp for a vehicle including a lamp unit having a light source, which is a functional part, and a lens provided inside a vehicle room, which is a decorative part, the lens is engaged with the lamp unit through an inner peripheral edge of an opening in a roof trim, thereby to clamp the roof trim between them and to attach the interior illumination lamp for a vehicle in a state where the roof trim is clamped. The lamp unit is provided with a plurality of positioning projections at a position where the lamp unit is contacted with the roof trim.

Abstract: There is provided an on-board interior illumination unit which is so strong as to withstand vibration, high temperatures and low temperatures, and tensile load, to thereby be superior in contact reliability and which can be made small in size.

Abstract: An illuminating lamp which can be easily assembled is provided. The illuminating lamp includes a decorative component including a mounting member mountable to an opening provided to a roof trim of a vehicle and a lens mounted on a compartment side of the mounting member, and a functional component including a light source and a holder which holds the light source and is mounted to the mounting member. The mounting member includes a flat plate to which the holder is mounted, an aperture provided at the flat plate to transmit light into the compartment, and a cover portion receiving the light source and reflecting the light of the light source into the compartment. The cover portion includes an opening portion at one end thereof along a longitudinal direction of the flat plate through which the light source is inserted along the flat plate.

Abstract: Disclosed is a bulb socket structure for an onboard interior lighting system, in which: a bulb attachment hole 12 to which a wedge base bulb 21 is attached is formed in a resin-made housing 10 constituting the onboard interior lighting system; and power supply terminals 15 configured to contact, and conduct electricity to, terminals of a base 21b arranged under a bulb part 21a of the wedge base bulb when the base is inserted into the inside of the bulb attachment hole are provided in the inside of the bulb attachment hole. In the bulb socket structure, a spacer 30 is provided to the bulb attachment hole 12. The spacer is includes a supporting cylindrical part 31 capable of supporting the bulb part 21a of the wedge base bulb from its outer periphery. The spacer is capable of causing the power supply terminals 15 to contact the respective terminals of the base part while protecting the power supply terminals.
