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. ## Claims ### Claim 1 A conveyance light emitting unit comprising: a detector configured to detect an object approaching a conveyance; a light emitter attached to the conveyance; and a controller configured to control the light emitter when the detector has detected the object, wherein the controller controls the light emitter such that a light emitting spot of the light emitter moves along a direction corresponding to a movement direction of the object detected by the detector. ### Claim 2 (depends on 1) The conveyance light emitting unit according to claim 1, wherein when the detector has detected the object approaching the conveyance from a rear side of the conveyance in a forward traveling state or a stop state, the controller controls the light emitter such that the light emitting spot moves forward from the rear side in a front-to-rear direction of the conveyance. ### Claim 3 (depends on 1) The conveyance light emitting unit according to claim 1, wherein when the detector has detected the object approaching the conveyance from a front side of the conveyance in a forward traveling state, the controller controls the light emitter such that the light emitting spot moves backward from the front side in a front-to-rear direction of the conveyance. ### Claim 4 (depends on 1) The conveyance light emitting unit according to claim 1, wherein when the detector has detected the object, the controller identifies at least one item of a distance between the conveyance and the object and an approaching speed when the object is approaching the conveyance, and controls the light emitter such that the light emitting spot moves at a movement speed corresponding to an identified result of the item. ### Claim 5 (depends on 4) The conveyance light emitting unit according to claim 4, wherein when identifying the distance, the controller controls the light emitter such that the light emitting spot moves faster as the distance decreases and moves slower as the distance increases, and when identifying the approaching speed, the controller controls the light emitter such that the light emitting spot moves faster as the approaching speed increases and moves slower as the approaching speed decreases. ### Claim 6 (depends on 1) The conveyance light emitting unit according to claim 1, wherein the light emitter emits light such that the light emitting spot moves while blinking, and when the detector has detected the object, the controller identifies at least one item of a distance between the conveyance and the object and an approaching speed when the object is approaching the conveyance, and controls the light emitter such that the light emitting spot moves while blinking at a blinking speed corresponding to an identified result of the item. ### Claim 7 (depends on 1) The conveyance light emitting unit according to claim 1, wherein an emission color of the light emitting spot is variable, and when the detector has detected the object, the controller identifies at least one item of a distance between the conveyance and the object and an approaching speed when the object is approaching the conveyance, and controls the light emitter such that the emission color of the light emitting spot changes to a color corresponding to an identified result of the item. ### Claim 8 (depends on 1) The conveyance light emitting unit according to claim 1, wherein the light emitter includes two light emitters provided separately from each other in a width direction of the conveyance, and when the detector has detected the object, the controller identifies a position of the object relative to the conveyance, and causes only one, which corresponds to an identified result of the position, of the two light emitters to emit light. ### Claim 9 (depends on 1) The conveyance light emitting unit according to claim 1, wherein the light emitter is arranged at a front portion of a member facing an inside of a room of the conveyance among members forming a door provided at the conveyance.
