[1] A casing (1) that is disposed on the ceiling (3) in the cabin (2) of the vehicle (1) and that incorporates the light source (20) in a state in which the light emitted from the light source (20) is directed at least laterally. 11, 11A to 11C) in the lighting device (10, 10A to 11C),
The casing (11, 11A to 11C) reflects a part of the light emitted from the light source (20) downward, and the reflecting surface (14a to 14a) illuminates the cabin (2) by the reflected indirect light. 14d) on the inner side of the casing body (12, 12A to 12C) and a receiving part (15, 15A) for hanging down integrally below the casing body (12, 12A to 12C) and attaching the light source (20) ~ 15C), and
Of the light emitted from the light source (20), the casing (11, 11A to 11C) is an edge of the casing body (12, 12A to 12C) and an end of the receiving portion (15, 15A to 15C). The lighting device (10, 10A to 11C) is characterized in that direct light traveling from the edge to the side reaches the vicinity of the boundary between the ceiling part (3) and the side wall surface part (4). .

［２］前記ケーシング（１１，１１Ａ〜１１Ｃ）は、前記光源（２０）から出射された光のうち、前記ケーシング本体（１２，１２Ａ〜１２Ｃ）の端縁と前記受け部（１５，１５Ａ〜１５Ｃ）の端縁との間から側方に向かう直接光が、前記天井部（３）と側壁面部（４）の境界に沿って照射する状態に設置されることを特徴とする［１］に記載の照明装置（１０，１０Ａ〜１１Ｃ）。 [2] The casing (11, 11A to 11C) includes an edge of the casing body (12, 12A to 12C) and the receiving portion (15, 15A to 15C) out of the light emitted from the light source (20). direct light toward the side from between the edge of), characterized in that installed in a state that elevation irradiation along the boundary of the ceiling (3) and sidewall portions (4) in [1] Illumination device (10,10A-11C) of description.

次に、前述した解決手段に基づく作用を説明する。
前記［１］に記載の照明装置（１０，１０Ａ〜１１Ｃ）によれば、光源（２０）は少なくとも側方に光を出射する状態でケーシング（１１，１１Ａ〜１１Ｃ）に組み込まれており、光源（２０）から出射された光の一部は、ケーシング本体（１２，１２Ａ〜１２Ｃ）にある反射面（１４ａ〜１４ｄ）によって下方へ反射される。この反射した間接光によって、客室内（２）は照らされる。また、光源（２０）から出射された光の一部が、客室側である下方にも向かう場合、かかる下方に向かう直接光は、ケーシング本体（１２，１２Ａ〜１２Ｃ）より下方に一体に垂下した受け部（１５，１５Ａ〜１５Ｃ）によって遮られる。 Next, the operation based on the above solution will be described.
According to the illumination device (10, 10A to 11C) described in [1], the light source (20) is incorporated in the casing (11, 11A to 11C) in a state of emitting light at least to the side, Part of the light emitted from (20) is reflected downward by the reflecting surfaces (14a to 14d) in the casing body (12, 12A to 12C). The cabin (2) is illuminated by the reflected indirect light. Also, part of the light emitted from the light source (20) is, if even downward a room side, direct light toward such downward, was suspended integrally from the lower casing body (12,12A～12C) It is blocked by the receiving parts (15, 15A to 15C).

より具体的には、前記［２］に記載したように、ケーシング（１１，１１Ａ〜１１Ｃ）を、光源（２０）から出射された光のうち、ケーシング本体（１２，１２Ａ〜１２Ｃ）の端縁と受け部（１５，１５Ａ〜１５Ｃ）の端縁との間から側方に向かう直接光が、天井部（３）と側壁面部（４）の境界に沿って照射し、当該付近に展開された広告（６）の全面を照射する状態に設置すると良い。ここでの「状態」とは、ケーシング（１１，１１Ａ〜１１Ｃ）の取り付け位置や向き、角度ないし傾斜の姿勢等を意味する。 More specifically, as described in [2] above, the casing (11, 11A to 11C) is used as the edge of the casing body (12, 12A to 12C) out of the light emitted from the light source (20). And direct light directed sideways from between the edges of the receiving portions (15, 15A to 15C) were irradiated along the boundary between the ceiling portion (3) and the side wall surface portion (4), and developed in the vicinity . It is good to install in the state which irradiates the whole surface of advertisement (6). Here, the “state” means the mounting position and orientation of the casing (11, 11A to 11C), the angle or the inclination posture, and the like.
