Next, the arrangement configuration of the LEDs 25 in the vehicle lighting device 20 will be described.
First, among the plurality of LEDs 25, the LED 25 </ b> A disposed at the upper left end in FIG. 4 is disposed in the vicinity of the standing wall portion 55 </ b> A in the LED substrate 31. In this embodiment, the LED 25 has a wide directivity angle (about 120 °), and the arrangement of the LED 25A is within the directivity angle of light emitted from the LED 25A (shown by a one-dot broken line) as shown in FIG. The outer lens 60 is set to have a portion 63A facing the insertion hole 52A. Further, among the plurality of LEDs 25, the LED 25 </ b> B- 1 disposed at the lower center portion in FIG. 4 and the LED 25 </ b> B- 2 disposed at the lower right end are disposed in the vicinity of the standing wall portion 55 </ b> B of the LED substrate 31. In the present embodiment, the LEDs 25B-1 and 25B-2 are arranged such that, as shown in FIG. 2, the outer sides of the LEDs 25B-1 and 25B-2 are arranged within the directivity angles (indicated by a dashed line) of the light emitted from the LEDs 25B-1 and 25B-2.

Next, the operation of the vehicle lighting device 20 will be described.
First, of the light emitted from the LED 25A, the light toward the portion 63A facing the insertion hole 52A in the outer lens 60 enters the outer peripheral surface of the standing wall portion 55A. At this time, as shown in FIG. 3, the outer peripheral surface of the standing wall portion 55 </ b> A is a flat curved surface without unevenness, and is less likely to affect the optical path of light from the LED 25 </ b> A. The light incident from the outer peripheral surface of the standing wall portion 55A travels inside the standing wall portion 55A having high translucency and is emitted from the inner peripheral surface of the standing wall portion 55A. At this time, similarly to the outer peripheral surface, the inner peripheral surface is also a flat curved surface, and it is difficult to affect the optical path of the light from the LED 25. In this manner, the light traveling from the LED 25A toward the portion 63A facing the insertion hole 52A of the outer lens 60 is transmitted through the standing wall portion 55A at a high rate and is incident on the portion 63A. In addition, as for the standing wall part 55B mentioned later, the outer peripheral surface and inner peripheral surface are hard to influence the optical path of the light from LED25 similarly to the standing wall part 55A.

  Further, light emitted from the LED 25B-1 toward the portion 63B (right side in FIG. 2) facing the insertion hole 52B in the outer lens 60 is incident on the outer peripheral surface from the left side of the standing wall portion 55B shown in FIG. To do. On the other hand, of the light emitted from the LED 25B-2, the light toward the portion 63B (left side in FIG. 2) facing the insertion hole 52B in the outer lens 60 is incident on the outer peripheral surface from the right side of the standing wall portion 55B shown in FIG. To do. The light incident from the outer peripheral surface of the standing wall portion 55B travels inside the standing wall portion 55B having a large translucency, and the light from the LED 25B-1 is mainly from the inner peripheral surface of the standing wall portion 55B to the right side and from the LED 25B-2. Are mainly emitted from the inner peripheral surface of the standing wall portion 55B to the left side. In other words, the light from the LED 25B-1 and the LED 25B-2 is emitted in a direction intersecting with each other from the inner peripheral surface of the standing wall portion 55B. In this way, light traveling from the LEDs 25B-1 and 25B-2 toward the portion 63B facing the insertion hole 52B of the outer lens 60 is transmitted through the standing wall portion 55B at a high rate and is incident on the portion 63B from different directions. To do.

  On the other hand, of the light emitted from the LED 25, the light that is not incident on the standing wall portion 55 is mainly incident on the back surface of the general portion 51 and is uniformized by the light diffusion portion 53 and emitted from the surface of the general portion 51. Is done.

  The light emitted from the inner lens 50 enters the back surface of the outer lens 60. Specifically, light emitted from the standing wall portion 55A is mainly incident on the portion 63A facing the insertion hole 52A in the outer lens 60, and mainly on the portion 63B facing the insertion hole 52B in the outer lens 60. Light emitted from the standing wall portion 55B enters. Further, light emitted from the general portion 51 is incident on the other portions of the outer lens 60. The light incident on the outer lens 60 is made uniform by the light diffusion portion of the outer lens 60 and is emitted from the design surface of the outer lens 60 into the vehicle interior. As described above, in the vehicle lighting device 20, the amount of light emitted from the design surfaces of the portions 63 </ b> A and 63 </ b> B facing the insertion holes 52 </ b> A and 52 </ b> B in the outer lens 60 is sufficient. It is assumed that the surface has no unevenness or is suppressed in the illuminance distribution.

Then, the attachment method with respect to the vehicle of the illuminating device 20 for vehicles is demonstrated using FIG.
First, the lamp assembly 21 is assembled by attaching the inner lens 50 to the base member 30 on which the LEDs 25 are arranged (inner lens attaching step). Specifically, the inner lens side locking claw 58 of the inner lens 50 is locked to the inner lens locked portion 43 of the housing 40 that houses the LED substrate 31 (see FIG. 1). In the lamp assembly 21, the standing wall portion 55 is disposed on the side of the round terminal 36, and the positional deviation of the round terminal 36 to the side is restricted. The inner lens attaching step is performed before each member is mounted on the vehicle.

  Next, as shown in FIG. 5, the lamp assembly 21 is screwed to the vehicle ceiling to which the ceiling interior material 12 is attached. Specifically, the screw member 14 is inserted from the insertion hole 52 of the inner lens 50, and the shaft portion 15 is screwed into the screw hole of the attachment portion 11 via the round terminal 36 and the through hole 46. At this time, the screw member 14 is guided to the pedestal portion 45 by the standing wall portion 55, and does not fall between the LED substrate 31 and the general portion 51 of the inner lens 50, for example. Then, the base portion 45 of the housing 40 is sandwiched between the head portion 16 of the screw member 14 and the mounting portion 11 of the vehicle panel 10. Then, the round terminal 36 and the vehicle panel 10 are electrically connected via the screw member 14.

  Finally, the outer lens 60 is attached to the lamp assembly 21 attached to the vehicle (outer lens attachment step). Specifically, the outer lens side locking claw 61 of the outer lens 60 is locked to the outer lens locked portion 44 of the housing 40. In this way, the attachment of the vehicle lighting device 20 to the vehicle is completed.

Then, the effect of this embodiment is demonstrated.
According to the vehicular lighting device 20 of the present embodiment, by providing the inner lens 50 with the structure (the insertion hole 52 and the standing wall portion 55) relating to the attachment of the base member 30, the workability relating to the attachment can be improved. At the same time, it is possible to suppress the deterioration of the design property due to the provision of the insertion hole 52 and the standing wall portion 55. Specifically, the screw member 14 is mounted in the vehicle with the inner lens 50 attached to the base member 30 by providing the insertion hole 52 and the standing wall portion 55 for inserting the screw member 14 in the general portion 51 of the inner lens 50. The inner lens attaching step after the base member 30 is attached to the vehicle can be abolished. On the other hand, when such an insertion hole is provided, a portion of the outer lens facing the insertion hole may be visually recognized as a dark part. However, in the above-described configuration, the standing wall portions 55A and 55B of the inner lens 50 are lower in light diffusibility than the general portion 51, and the LED 25A and the LEDs 25B-1 and 25B-1 are disposed in the vicinity of the standing wall portions 55A and 55B, respectively. Thus, the light emitted from the standing wall portions 55A and 55B can be efficiently supplied to the portions 63A and 63B facing the insertion holes 52A and 52B in the outer lens 60, and the portions 63A and 63B are visually recognized as dark portions. The occurrence of the situation can be suppressed.

  Moreover, in this embodiment, the light which goes to a mutually different direction is supplied to the part 63B facing the insertion hole 52B in the outer lens 60 from LED25B-1 and LED25B-2 arrange | positioned in the position which pinches | inserts the insertion hole 52B. And the occurrence of a situation where the portion 63B is visually recognized as a dark portion can be further suppressed. In the present embodiment, it is possible to supply light toward both sides to a portion 63B of the outer lens 60 facing the insertion hole 52B corresponding to the insertion hole 52B arranged in the center, which is particularly preferable.

  Further, in the present embodiment, the standing wall portion 55 is erected so that the front end portion 56 is located at the same position as the seat surface 47 in the direction in which the inner lens 50 and the base member 30 are arranged. Therefore, when the screw member 14 and the LED 25 are connected via the round terminal 36 and the screw member 14 is used as a bus bar, the round terminal 36 is held on the seat surface by the standing wall portion 55 before the screw member 14 is fastened. It is possible to further improve the workability related to attachment to the vehicle.

  In the present embodiment, the standing wall portion 55 has a gap formed between the front end portion 56 and the plate surface 32 of the LED substrate 31 smaller than the width dimension of the head portion 16 of the screw member 14. . For this reason, when fastening the screw member 14, the occurrence of a situation in which the screw member 14 falls into the gap between the standing wall portion 55 and the LED substrate 31 can be suppressed, and workability related to attachment to the vehicle can be further improved. This can be further improved.
