One or more light sources, one or more detectors, a processor, and a controller are configured to provide spot illumination that follows a moving object, a moving occupant, or a portion of a moving occupant in the vehicle.

An illumination lens includes an incident face (510), being provided in a recessed manner in a bottom apex part of the lens body (51), and receiving light from the light source (41); a reflection face (520) on the inner side of an outer periphery of the lens body (51), totally reflecting the light, having reached from the incident face (510); and an emission face (530) at the upper end of the lens body (51), emitting the light, having reached from the incident face (510) and the reflection face (520), to the outside, and the incident face (510) distributes the light, which could be directed toward the entire region of the reflection face (520), only in a predetermined range (521) within the reflection face, being adjacent to the upper end side portion, following the emission face (530), and being closer to the bottom apex part.

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.

A vehicle includes a vehicle body that defines a cargo space. The cargo space includes a cargo floor. A trim member is disposed on the vehicle body within the cargo space. The trim member defines an opening. The housing is disposed within the opening. A light source is disposed on the housing. A first lens is disposed adjacent to the light source. The first lens defines a first optic. A second lens is spaced-apart from the first lens. The second lens defines a second optic. The light source is configured to emit light through the first lens and the second lens into the cargo space.

A lighting device includes a white LED, a full-color LED, and a reflecting portion. The reflecting portion reflects light from the white LED and the full-color LED. A microcomputer turns on the full-color LED to emit light containing a red light component while the white LED is on. Further, the white LED and the full-color LED are arranged so that reflected lights thereof reflected by the reflecting portion are mixed to perform illumination. Thereby, direct lights of the white LED and the full-color LED cannot be visually recognized. Further, light from the white LED with a lot of blue components is compensated with light containing a red component from the full-color LED, and spectral distribution can be made even and illumination close to that of natural light can be performed.
