A left vehicle lamp (L) includes a lamp housing (), a lamp cover () that covers an opening of the lamp housing (), an illumination unit () that is disposed inside a lamp chamber (S) formed by the lamp housing () and the lamp power bar (), a radar () configured to acquire a radar data indicating a surrounding environment of a vehicle by emitting radio waves toward the outside of the vehicle, and a light guide member () that is disposed in a manner of facing the radar () so as to hide at least a part of the radar () from the outside of the vehicle and is configured to transmit radio waves emitted from the radar (). The radar () is disposed outside the housing (S). The light guide member () is configured to emit light toward the outside of the vehicle.

Vehicle light fitting, radar module, radar, and vehicle

A left vehicle lamp includes a lamp housing, a lamp cover that covers an opening of the lamp housing, an illumination unit that is disposed inside a lamp chamber formed by the lamp housing and the lamp power bar, a radar) configured to acquire a radar data indicating a surrounding environment of a vehicle by emitting radio waves toward the outside of the vehicle, and a light guide member that is disposed in a manner of facing the radar so as to hide at least a part of the radar from the outside of the vehicle and is configured to transmit radio waves emitted from the radar. The radar is disposed outside the housing. The light guide member is configured to emit light toward the outside of the vehicle.

To improve design characteristics when the light fixture is turned on in a vehicle light fixture including a plate-shaped light guide. The plate-shaped light guide () is configured such that light from five light sources (AAAAandA) is totally reflected by a plurality of reflective elements () formed on a first plate surface () on a rear surface side of the plate-shaped light guide, and then emitted forward of a light fixture unit from a second plate surface () of the plate-shaped light guide. At that time, five light emitting regions (AAAAandA) are arranged at intervals in a horizontal direction in the plate-shaped light guide (), and then the reflective elements () are arranged in a state of being continuously side by side along a line L extending in a direction intersecting the horizontal direction in each of the light emitting regions (AtoA). Each reflective element () is formed in a substantially concave spherical surface shape. In addition, the light sources (AtoA) are configured to be able to be individually turned on in a state of being respectively arranged in the light emitting regions (AtoA).

Vehicle light fixture

A vehicle lamp includes a light source and a plate-shaped light guide including a first plate surface on which a plurality of reflective elements are formed and a second plate surface. The plate-shaped light guide is configured to totally reflect light from the light source by the plurality of reflective elements. The plurality of reflective elements are arranged in a state of being continuously arranged along a line extending in a direction, and are arranged in a plurality of rows on the line. The plate-shaped light guide is configured to allow the light from the light source to reach a position of the line from a first direction. Each of the reflective elements has a substantially concave curved surface shape, and as compared to reflective elements constituting a first row, reflective elements constituting a second row is formed at a deeper position from the first plate surface.

Vehicle lamp

A vehicle lamp has a roof unit. The roof unit includes a plurality of types of light output units having different illumination functions, a light emission drive unit configured to cause the plurality of types of light output units to output lights, and a monitoring sensor. The roof unit is arranged at a roof part of a vehicle.

A vehicle lamp includes a light source and a plate-shaped light guide body. The plate-shaped light guide body is configured to totally reflect light from the light source that is incident on the plate-shaped light guide body by a plurality of reflective elements formed on a first plate surface of the plate-shaped light guide body, and then, to emit the light from a second plate surface of the plate-shaped light guide body toward the front side of the vehicle lamp. The plurality of reflective elements are disposed in a state of being continuously arranged along a line extending in a required direction. Each of the reflective elements has a substantially concave spherical surface shape or a substantially convex spherical surface shape.

Vehicle lamp having a plate shaped light guide body

A vehicle lamp includes a plurality of types of light output units having different illumination functions, a light emission drive unit configured to cause the plurality of types of light output units to output lights, and a monitoring sensor. The vehicle lamp is arranged at an upper part of a vehicle.
