Indoor illumination lamp

A vehicle interior lamp includes a housing having an opening, a lens arranged at the opening, a compartment provided in the housing and surrounding the opening at which the lens is arranged, a light source arranged in a corner of the compartment and emitting light toward the lens, and a reflector arranged inside the compartment, the reflector for introducing the light emitted from the light source to the lens. A plurality of steps is provided on a surface of the lens facing the light source, the steps having a thickness that reduces as the distance from the light source increases and arranged to be brought close uniformly a brightness of a surface of the lens by the light source. The lens is provided with a protrusion or a serration.

Vehicle interior lamp

The switch structure is configured to have a switch knob, a lens for transmitting the light of a bulb in the interior of a vehicle, a bus bar connected between the bulb side and the power source side (not shown), and a convex portion protruding toward the switch knob. A conductive element is formed to have a bulb-side abutment portion that abuts on a bulb-side bus bar and is connected thereto and a power source side abutment portion that abuts on a power source side bus bar and is connected thereto. When attached to an operating element, the conductive element is configured to be retractable in a push direction and to be rotatable in a rotational direction relative to the operating element and slidably contacts with the bus bar upon rotation of the switch knob.

Switch structure

A mounting structure including: an outer housing having a first locking portion; a ceiling including a lamp opening portion in a central portion thereof; an inner housing including: a first locking facing portion which is locked in the first locking portion of the outer housing; and a second locking portion on and directly attached to the inner housing; and a reinforcement having a second locking facing portion which is locked on the second locking portion of the inner housing. The ceiling is fixed between the outer housing and the inner housing by locking the first locking facing portion of the inner housing in the first locking portion of the outer housing via the lamp opening portion in the ceiling. A bracket portion shaped so as to follow a shape of an upper side of the ceiling is provided along an outer circumference of the inner housing.

Mounting structure for automotive room lamp

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.

Interior illumination lamp for vehicle

The present invention provides an assembly structure of a vehicle room lamp which can be manufactured at low cost and high productivity, and has a low weight. The assembly structure includes an inner housing including a body which has a first surface and a second surface, a bracket portion formed in an outer periphery of the body, and a guide rod extending from the second surface; an outer housing attached to the inner housing on the first surface; a ceiling part including an opening through which the outer housing attached to the inner housing, and an edge of the opening which is supported by the bracket portion; and a reinforcement including a guide hole into which the guide rod is inserted.
