There are disclosed video systems and methods that use a camera in a lamp housing for a tractor-trailer. Within the housing is an electrical subsystem with a PLC interface and an electrical connector disposed outside the housing and adapted to connect to the trailer and draw power therefrom. A lamp mounted in the housing is connected and adapted to draw power through the electrical subsystem and emit light through a cover of the housing. The camera mounted in the housing has a field of view through the cover. The camera is connected and adapted to draw power through the electrical subsystem and to capture images through the cover and is further connected to the PLC interface. The PLC interface converts data from the camera and transmits the converted data through the electrical connector to the trailer.

A lighting apparatus includes light emitting elements having an emission peak wavelength of 400 to 510 nm, a first phosphor having an emission peak wavelength of 485 to 700 nm, a second phosphor having an emission peak wavelength of 510 to 590 nm, a third phosphor having an emission peak wavelength of 600 to 700 nm, and a color filter having transmittance for light with a wavelength of 600 to 730 nm that is 80% or more and transmittance for light with a wavelength of 410 to 480 nm that is 3% or more and 50% or less. The color filter transmits a part of light emitted from the first phosphor, at least a part of light emitted from the second phosphor, and at least a part of light emitted from the third phosphor. Light transmitted through the color filter is emitted to the outside.

A second light source, a second incidence section and a second reflecting section in a vehicle lamp are disposed closer to a light guide section than a first light source, a first incidence section and a first reflecting section, a stepped section is provided between the first reflecting section and the second reflecting section, and the first reflecting section is disposed at above the stepped section and the second reflecting section is disposed at below the stepped section when seen from a side of the first incidence section and a side of the second incidence section.

Provided is a vehicle signal light in which a person with protanopia (p-type color vision deficiency) can perceive whether or not the vehicle signal light, e.g., a stop lamp, a tail lamp, or the like, is turned on. The vehicle signal light includes a first light source configured to emit red light and a second light source configured to emit amber light. The first light source and the second light source are simultaneously turned on and are configured to emit light with a higher luminous intensity in response to a braking operation, and the emission intensity of the first light source is higher than that of the second light source.

Various embodiments of a combination lamp are provided, which combine a plurality of different lamp functions in a unitary configuration, and can reduce the total amount of space taken up for at least substantially the same amount of illumination produced. The combination lamps can be configured for use on vehicles, light fixtures, free standing lamps, decorative articles, etc. In some embodiments, each lamp component may have a power connection element independent from the other lamp components.

A light-emitting assembly configured to generate varied color light includes an assembly housing. The light-emitting assembly also includes a light filter element fixed relative to the assembly housing. The light filter element includes a plurality of transparent nanostructured ElectroChromic (TNEC) layers. When at least one of the plurality of TNEC layers is subjected to voltage, the subject TNEC layer(s) imparts a distinct reflective color to ambient light entering the light-emitting assembly. Such a light-emitting assembly may be specifically adapted for use on a motor vehicle.

In a vehicle lamp body device provided with a first light source arranged at a center of a base and second light sources arranged at both ends of the base, the device includes a first lightguide rod configured to branch and guide light from the first light source to an outside of both ends of the base and a second lightguide rod configured to guide light from the second light sources to the outside of both ends of the base respectively, the first lightguide rod and the second lightguide rod are superimposed in a light emission direction on the outside of both ends of the base and optical paths of the first lightguide rod and the second lightguide rod are merged.

A light guide system for a vehicle includes, among other things, a housing that includes a first section and a second section that are secured together to provide a chamber A light emitter is disposed within the chamber. A light source is disposed outside the chamber A reflector system directs light emitted from the light source to the light emitter within the chamber. A vehicle lighting method includes, among other things, securing a first and second section of a housing assembly together to provide a chamber, and operatively coupling a reflector system within the chamber and a light source outside the chamber such that the reflector system can redirect light from the light source to a light emitter held within the chamber.

Disclosed is a system for making a vehicle lamp have an overall solid occluded appearance when the lamp is inactive, and allowing for the passage and optional filtering of light when the lamp is on. A light modifier is created that has optical elements on an inside surface, and an opaque or translucent covering on an opposite side of the modifier. The optical elements and corresponding apertures are aligned with each other and diversely configured.
