Zusammenfassung:	To contribute to miniaturization and cost reduction while providing both of spot lighting and surface lighting.SOLUTION: A lighting device includes: a light-emitting part; a projector lens for projecting light that is emitted from the light-emitting part; and a switching part for switching lighting between spot lighting and surface lighting by changing a focal distance. The lighting device can be applied to a lighting device for a ranging module for measuring a distance to a subject, for example.SELECTED DRAWING: Figure 4 【課題】スポット照明と面照明の両方を実現しつつ、小型化および低価格化に貢献できるようにする。【解決手段】照明装置は、発光部と、発光部から出射される光を投射する投射レンズと、焦点距離を変更することで、スポット照射と面照射とを切り替える切り替え部とを備える。本技術は、例えば、被写体までの距離を測定する測距モジュールの照明装置等に適用できる。【選択図】図４
