A lighting device for a vehicle includes a map lamp, left and right rear seat reading lamps, left and right trunk lightings, left and right rear gate lightings, and left and right rear pillar lightings. The map lamp, the left rear seat reading lamp, the left trunk lighting, the left rear gate lighting, and the left rear pillar lighting are disposed along a left connecting line. In addition, the map lamp, the right rear seat reading lamp, the right trunk lighting, the right rear gate lighting, and the right rear pillar lighting are disposed along a right connecting line. The left and right connecting lines extend such that a gap in a vehicle width direction is gradually reduced from a rear side of the vehicle toward a front side of the vehicle.

A system (100) and method (900) for illuminating the interior space (90) of a trailer (84). The system (100) can utilize a power box (200) to draw and store electricity from a tractor (82) and use that electricity to activate LED assemblies (300) within the trailer (84) is untethered from the tractor (82). The lights (310) can be activated by a motion sensor (340) associated with the location of the lights (310) being activated.

A slide device includes an upper rail to which a slide seat for a vehicle is attached, a slide rail to which the upper rail is slidably attached, a light emitter, and an attachment portion that attaches the light emitter to the upper rail. The attachment portion is attached to the upper rail such that the light emitter is arranged outside the slide rail. According to the slide device, since the attachment portion is attached to the upper rail such that the light emitter is positioned outside the slide rail, the light emitter does not move inside the slide rail to which a large amount of grease is applied, and a decrease in communication performance can be prevented.

In one embodiment, a linear light emitting device comprises one or more linear extrusions collectively comprising a horizontal mounting extension, an array of light emitting diodes, a vertical support, and a linear support platform. In one embodiment, the light emitting device comprises a mounting extension that extends from the light emitting device for the bottom surface of the mounting extension to be mounted to a top rail of a vehicle cargo compartment (such as a trailer or cargo compartment of a truck) and a vertical support that positions a linear array of light emitting diodes above the top rail and oriented at a first orientation angle, such as 45 degrees, to the bottom surface of the horizontal mounting surface. In one embodiment, the linear light emitting device is mounted between two roof bows or below one or more roof bows.

A vehicular interior lighting device includes a main body portion fixed to an inside surface of a roof, a light source accommodated in the main body portion, a light shielding cover portion constituting a housing with the main body portion and covering the light source from below, and a light guide member having a protruding portion protruding along the inside surface from a gap between the main body portion and the cover portion. The light guide member has a diffusion portion formed on a surface of the protruding portion facing downward and diffusing light, a first light guide portion guiding light emitted from the light source to the protruding portion, and a reflecting portion reflecting light guided by the first light guide portion toward the diffusion portion.

An LED control system is provided for connection to an LED lighting system via a power line to control the LED lighting system using commands formed by manipulation of frequency and amplitude of a signal transmitted over the power line. The signal may be for example a wave or a sequence of pulses. The signal may be provided in superposition with line power or the line power may be formed as the signal.
