A present invention is a vehicle lamp provided with: an elongated light guide member provided in a lamp chamber, an incident end part being positioned below said member; and a light source provided in the lamp chamber so as to face the incident end part. The light guide member has: a light guide main part having an elongated shape in which one end is the incident end part, a prism part being provided along the longitudinal direction, the prism part causing a portion of the light incident from the incident end part to be emitted in the irradiation direction; and a flange part projecting from the light guide main part in the direction intersecting the irradiation direction. The flange part is provided with a reflecting surface that forms a depression angle with a projecting end face when viewed from the incident end part side within a prescribed range viewed in the longitudinal direction.

Disclosed is a fluorescent diffusion board for lighting including a first layer containing an inorganic material and a polycarbonate resin and a second layer formed on one surface of the first layer and configured to contain a polycarbonate resin and a fluorescent material.

A method for checking the plausibility of detected features of a light distribution of a headlamp of a motor vehicle includes irradiating, by the headlamp, a scene in surroundings of the motor vehicle; capturing, by a camera of the motor vehicle, the irradiated scene in an image; dynamically seeking and identifying at least one initial optical feature in the image, adaptively producing and analyzing local surroundings of the at least one initial optical feature; dynamically extracting at least one further optical feature from the local surroundings; and carrying out, using a learned algorithm and on the basis of the at least one initial optical feature and the at least one further optical feature, an adaptive check as to whether the at least one initial optical feature and the at least one further optical feature are plausibly arranged in the local surroundings.

A vehicle is provided herein that includes a pickup box defining a storage compartment therein. A liner is disposed on an exterior surface of the pickup box. A first luminescent structure is disposed within the liner and is configured to luminesce in response to receiving excitation light from a first light source.
