A lamp for an automobile, which includes: a light source; a first light guide unit provided on one side of the light source to face the light source; and a second light guide unit provided on the one side of the light source to face the light source and at least a portion of which is surrounded by the first light guide unit. The first light guide unit includes: a first light guide region which forms one end of the first light guide unit and to which a portion of the light emitted from the light source is incident; and a second light guide region which forms the other end of the first light guide unit and to which another portion of the light emitted from the light source is incident. The second light guide unit is provided between the first and second light guide regions.

A light-emitting apparatus includes; a light-emitting device including a photoluminescent layer that receives excitation light and emits light including first light having a wavelength λ.sub.a in air, and a light-transmissive layer located on or near the photoluminescent layer; and an optical fiber that receives the light from the photoluminescent layer at one end of the optical fiber and emits the received light from the other end thereof. A surface structure is defined on at least one of the photoluminescent layer and the light-transmissive layer, and the surface structure has projections or recesses or both and limits a directional angle of the first light having the wavelength λ.sub.a in air.

A vehicle control device includes a steering wheel including an annular rim portion and a spoke portion that extends inward from the rim portion, an indicator that is disposed on the spoke portion and is able to be lit, and a controller that controls a lighting state of the indicator according to a state of driving assistance.

It is intended to cause a light emitter to properly emit light for notifying an occupant of a movement direction of an object approaching a conveyance. A vehicle lighting device includes sensors (3a, 3b, 3c, 3d) configured to detect an approaching object approaching a vehicle, light emitters (5) attached to the vehicle, and a control device (2) configured to control the light emitter (5) when the sensor (3a, 3b, 3c, 3d) has detected the approaching object. The control device (2) controls the light emitter (5) such that a light emitting spot of the light emitter (5) moves along a direction corresponding to a movement direction of the approaching object.
