Part of the movable module 20 (see FIGS. 1B and 1C) exposed from 6a (see FIGS. 1B, 1C, 1D, and 7) (see FIG. 1B). Specifically, by touching the light guide lens 4 (see FIG. 1B, FIG. 1C, FIG. 1D, and FIG. 4), the movable module 20 with respect to the lighting device housing 6 is touched. The operation of rotating is performed.

  If the suspension member 9 (see FIGS. 1A, 1B, 1C, and 11) is formed of a non-flexible material, the suspension member 9 Abutting on the spherical surface 5a of the joint member 5 (see FIGS. 1B, 1C, 5 and 12), the spherical surface 4a of the light guide lens 4 (FIG. 1B, FIG. 1C), A large frictional force is generated between FIG. 1 (D) and FIG. 4) and the hole 6a of the lighting device housing 6 (see FIG. 1 (B), FIG. 1 (C), FIG. 1 (D) and FIG. 7). In this state, an operation of rotating the movable module 20 with respect to the lighting device housing 6 is performed as shown in FIG. For this reason, a relatively large force is required for the operation of rotating the movable module 20 with respect to the lighting device housing 6.

  In detail, in the illuminating device 100 of 1st Embodiment, when it is necessary to change the direction of the light irradiated from the illuminating device 100 as shown in FIG. 6a (see FIG. 1B, FIG. 1C, FIG. 1D and FIG. 7), by touching a part of the movable module 20 exposed, the suspension member 9 (FIG. 1A) 1B, FIG. 1C, and FIG. 11) are bent, that is, the movable module 20 is slightly moved from the right side to the left side in FIG. 1B. As a result, the spherical surface 4a of the light guide lens 4 is obtained. (See FIGS. 1B, 1C, 1D, and 4) and the frictional force between the hole 6a of the lighting device housing 6 is reduced.

  Therefore, according to the illuminating device 100 of 1st Embodiment, the movable module 20 can be rotated with respect to the illuminating device housing 6, as shown in FIG. That is, according to the lighting device 100 of the first embodiment, the rotational resistance of the movable module 20 with respect to the lighting device housing 6 is reduced as compared with the case where the suspension member 9 is formed of a material having no flexibility. be able to.

  In the lighting device 100 of the first embodiment, the suspension member 9 (see FIG. 11) is formed of a flexible material. However, in the lighting device 100 of the fourth embodiment, the suspension member 9 is used instead. It is also possible to arrange a compression coil spring between the movable member 20 and the movable module 20 (see FIG. 1) (specifically, the spherical surface 5a (see FIG. 5) of the joint member 5 (see FIG. 5)). When a compression coil spring having a small radius is used, a bearing member (spring seat member) that can slide with respect to the spherical surface 5a of the joint member 5 is disposed between the spherical surface 5a of the joint member 5 and the compression coil spring. .

  Specifically, in the lighting device 100 of the first embodiment, the amount of deflection of the suspension member 9 (see FIGS. 1A, 1B, 1C, and 11) is increased by an operation by the operator. When it becomes larger, the spherical surface 4a of the light guide lens 4 (see FIGS. 1B, 1C, 1D and 4) and the hole 6a of the lighting device housing 6 (FIG. 1B), 1C, 1D, and 7) may be separated from each other.

  Temporarily, the spherical surface 5a (refer FIG.1 (B), FIG.1 (C), FIG.5 and FIG.12) of the joint member 5, and the suspension member 9 (FIG.1 (A), FIG.1 (B), FIG.1 (C) If the operator rotates the movable module 20 with respect to the lighting device housing 6 as shown in FIG. 13, the joint member 5, the spherical surface 5a of the light guide lens 4 rolls with respect to the suspension member 9 without sliding with respect to the suspension member 9, and as a result, the spherical surface 4a of the light guide lens 4 (FIGS. 1B and 1C). 1D and FIG. 4) may deviate from the hole 6a of the lighting device housing 6 (see FIG. 1B, FIG. 1C, FIG. 1D, and FIG. 7). .

That is, according to the lighting device 100 of the first embodiment, the movable module 20 rotates with respect to the lighting device housing 6 as compared with the case where the spherical surface 5a of the joint member 5 and the suspension member 9 are in contact with each other only at one place. The stability of the operation can be improved.

  Furthermore, in the illumination device 100 of the first embodiment, as shown in FIGS. 1B and 1C, a ring-shaped power supply terminal 3 (see FIG. 1) for supplying a positive potential to the light emitting element light source 1. 3) is disposed on the same spherical surface as the spherical surface 4a of the light guide lens 4.

Therefore, according to the illuminating device 100 of 1st Embodiment, when the components which support the movable module 20 rotatably with respect to the illuminating device housing 6 and the components which cool the light emitting element light source 1 are provided separately. As a result, the number of parts can be reduced.

  In the sixth embodiment, the above-described first to fifth embodiments can be appropriately combined.

  The lighting device of the present invention can be applied to any of interiors and exteriors such as automobiles, airplanes, trains, ships, and buildings. The lighting device of the present invention can be applied to lighting devices that are required to be thin, such as seats, ceilings, doors, walls, and other product interiors.
