To provide an optical system, an illuminating system, a display system, and a moving body that can adjust introduction efficiency of light.SOLUTION: A light guide member 1 comprises an incident surface 10 on which light is incident, and a first surface 11 and a second surface 12 opposed to each other. In the light guide member 1, the second surface 12 is an emitting surface for the light. A prism 3 is provided in the first surface 11, and reflects the light passing through the inside of the light guide member 1, toward the second surface 12. A light control body 2C is located between a light source 4 and the incident surface 10, and controls the light outputted from the light source 4 and to be made incident on the incident surface 10. The light guide member 1 includes a direct light path L1 in which the light incident from the incident surface 10 is directly reflected by the prism 3 and emitted from the second surface 12. In the light control body 2C, an incident lens 21 that is a surface opposed to the light source 4 has a symmetrical shape.SELECTED DRAWING: Figure 1

    【課題】光の取り込み効率を調整可能な光学システム、照明システム、表示システム及び移動体を提供する。【解決手段】導光部材1は、光が入射する入射面10、並びに互いに対向する第1面11及び第2面12を有する。導光部材1は、第2面12が光の出射面である。プリズム3は、第1面11に設けられて、導光部材1の内部を通る光を第2面12に向けて反射する。光制御体2Cは、光源4と入射面10との間に位置し、光源4から出力されて入射面10に入射する光を制御する。導光部材1は、入射面10から入射した光をプリズム3にて直接反射して第2面12から出射させるダイレクト光路L1を含む。光制御体2Cにおける光源4との対向面である入射レンズ21は対称形状を有している。【選択図】図1
