To detect at least one of axis deviation and illuminance reduction of a lighting fixture.SOLUTION: A radar-mounted lighting fixture unit 1 comprises a head light 2, a light scanning unit 12, a light detection unit 13, and a control unit 14. The control unit 14 acquires light quantity detection data for each of a plurality of partial regions formed by dividing an object detection region within which the control unit 14 detects a reflection object outside a vehicle when the head light 2 performs irradiation with visible light. The control unit 14 determines whether the illuminance of the head light 2 is reduced and whether an axis of the head light 2 deviates based on a distribution of a normal partial region and an abnormal partial region within the object detection region. The normal partial region is a partial region where the light quantity indicated by the light quantity detection data is equal to or more than a region threshold. The abnormal partial region is a partial region where the light quantity indicated by the light quantity detection data is less than the region threshold.SELECTED DRAWING: Figure 1

    【課題】灯具の軸ズレおよび照度低下の少なくとも一方を検出する。【解決手段】レーダ搭載灯具ユニット1は、ヘッドライト2と、光走査部12と、光検出部13と、制御部14とを備える。制御部14は、ヘッドライト2が可視光の照射を実行しているときに、車両の外部において制御部14が反射物体を検出する物体検出領域を分割した複数の部分領域のそれぞれについて、光量検出データを取得する。制御部14は、物体検出領域内における正常部分領域および異常部分領域の分布に基づいて、ヘッドライト2の照度が低下しているか否か、及び、ヘッドライト2の軸がずれているか否かを判断する。正常部分領域は、光量検出データが示す光量が領域閾値以上となる部分領域である。異常部分領域は、光量検出データが示す光量が領域閾値未満となる部分領域である。【選択図】図1
