A variable-focus lighting device and a variable-focus lighting system have one light source and are used to adjust the position and focus of light that is emitted, among various positions in an interior space. An installation space on an interior roof is reduced and manufacturing costs are reduced.

Lighting may be provided using light sources such as lighting systems with arrays of light-emitting diodes. A lighting system may be integrated into a seat, a door panel, a dashboard, or other interior portions of a system such as a vehicle. The interior portions of the vehicle may be illuminated using lighting systems to provide ambient light, to provide custom surface textures and other decorative patterns, to provide icons, text, and other information, and to provide custom gauges and other illuminated regions. Illuminated regions may overlap sensors such as capacitive touch sensors, force sensors, and other sensors. The light-emitting diodes in a lighting system may supply light that passes through openings in a cover layer. The layer may be formed from fabric, leather, or other materials. Lens structures may guide light through the openings.

A lighting device includes a facet body, the interior of which is translucent and which includes a surface made of a plurality of flat facets. The facet body is arranged on an opening formed in a cover that outwardly delimits an inner region of the lighting device. The surface of the facet body includes a first surface section and a second surface section, the first surface section is outwardly exposed via the opening and is translucent, and the second surface section lies in the inner region and has a reflective layer with the exception of one or more translucent surface regions. A plurality of light sources are arranged in the inner region such that the light sources emit light into the facet body via the translucent surface region(s) of the second surface section.

When light is off, a transparent appearance is obtained, while when the light is on, light is seen through a transparent spot. The present invention includes a light source portion and a reflective portion. The light source portion emits light. The light source portion is disposed at a position shifted with respect to an emitting direction of emitted light from the reflective portion. The reflective portion reflects the light from the light source portion and emits it in a predetermined direction. The reflective portion is constituted by a transparent member with a refractive index at least in a visible light area larger than 1. As a result, in the present invention, the transparent appearance is obtained when the light is off, while the light is seen through the transparent spot when the light is on.

Provided herein is an indoor emotional lighting apparatus for implementing three-dimensional (3D) pattern for a vehicle, the indoor emotional lighting apparatus including a film portion on which a plurality of fine lenses each having a 3D pattern are arranged, a light source configured to emit light in a plurality of directions, and a light source guide portion configured to guide an optical path of the light source to allow the light emitted from the light source to be directed toward the film portion.
