A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a front view showing a vehicle door trim 10 to which a vehicle lighting device 20 of the present embodiment is attached. The vehicle door trim 10 is an interior material that is attached to the vehicle interior side of an inner panel (not shown), and constitutes a vehicle door together with the inner panel.

  The vehicle door trim 10 is for improving the appearance and comfort of the passenger compartment, and includes a trim board 10A and an ornament 10B attached to the trim board 10A. As shown in FIG. 1, the trim board 10A is divided into a lower board 11 constituting the lower part, a middle board 12 constituting the central part, and an upper board 13 constituting the upper part. The trim board 10A may be integrally formed of synthetic resin.

  The lower board 11, the middle board 12, and the upper board 13 are formed of a synthetic resin material such as polypropylene, or a material obtained by mixing natural fibers (such as kenaf) with a synthetic resin material. A skin material 15 (see FIG. 4) is attached to a part or all of the vehicle door trim 10 on the vehicle interior side. The boards 11, 12, and 13 are connected to each other by, for example, attaching a mounting boss formed on one board through a through-hole formed on the other board, and then attaching by a welding means such as ultrasonic welding. This is done by welding the tip of the boss. In addition, various board | substrate methods, such as a screw stop and a nail | claw fitting, can be used for the board | substrate 11, 12, 13 coupling | bonding.

  The middle board 12 is formed with an armrest portion 14 used as an occupant's armrest in a protruding manner on the vehicle interior side. An opening 14A that opens upward is formed on the upper surface of the armrest 14, and a pull handle (see FIG. 5) for opening and closing the vehicle door by inserting a finger into the opening 14A. Not shown).

  An inside handle housing portion 30 is attached to the upper board 13 near the junction with the middle board 12, and a handle portion 31A of the inside handle 31 for opening and closing the vehicle door is housed therein. ing. In addition, a switch base 16 having a switch operation unit (not shown) is provided at a position located below the inside handle housing unit 30 on the upper surface of the armrest unit 14.

  As shown in FIG. 4, the vehicle lighting device 20 according to the present embodiment includes a light source 50 for illuminating the inside of the inside handle housing portion 30 and the switch base 16, and a handle portion 31 </ b> A of the inside handle 31. . The inside handle accommodating portion 30 is mainly configured by an inside handle bezel 32 and an inside handle cover 33. In the following description, the inside handle housing portion 30 may be referred to as the housing portion 30, the inside handle bezel 32 may be referred to as the bezel 32, and the inside handle cover 33 may be referred to as the cover 33.

  As shown in FIGS. 2 and 4, the bezel 32 has a front-view shape and is arranged so as to open to the vehicle interior side. As shown in FIG. 3, the bezel 32 is provided with a mounting claw 35 that protrudes to the outside of the passenger compartment. The mounting claw 35 can be attached to the trim board 10A. The cover 33 is attached so as to cover the back wall of the bezel 32 from the vehicle interior side. That is, the cover 33 constitutes the back wall of the housing part 30.

  The light source 50 is disposed below the bottom wall 32A of the bezel 32 (the bottom wall constituting the inside handle housing portion). As shown in FIG. 4, a lower wall portion 32 </ b> B extending from the end portion of the bottom wall 32 </ b> A so as to cover the side and the lower side of the light source 50 is formed. In other words, as illustrated in FIG. 4, the bottom wall 32 </ b> A and the lower wall portion 32 </ b> B constitute a light source housing portion formed in a concave shape, and the light source 50 is housed in the light source housing portion.

  The bottom wall 32A is formed with a light emission hole 32E through which light emitted from the light source 50 can be emitted into the inside handle housing portion 30. On the other hand, a lower portion of the lower wall portion 32B is an inclined portion 32D having a shape that rises and inclines toward the vehicle interior side. A lower wall light emitting hole 32F is formed through the inclined portion 32D. The lower wall light emission hole 32F is for allowing light emitted from the light source 50 to pass therethrough.

  That is, the light emission hole 32E is an example of a bottom wall side light guide unit that can guide light emitted from the light source 50 into the inside handle housing unit 30. The lower wall portion light emission hole 32F is an example of a lower wall portion side light guide portion that can guide light emitted from the light source 50 downward.

  That is, in the present embodiment, the inside handle housing portion 30 can be illuminated by emitting light from the light source 50 through the light emitting hole 32E, and light is emitted from the light source 50 through the lower wall light emitting hole 32F. Thus, the switch base 16 disposed below the lower wall light emission hole 32F can be illuminated.

  In addition, the emission direction of the light emitted from the lower wall light emission hole 32F is not limited to the lower side (switch base 16 side). For example, the inclined portion 32D and the lower wall light emission hole 32F may be provided so that the emission direction of the light emitted from the lower wall light emission hole 32F is lateral (left side in FIG. 4).

  Further, a mounting hole 32G through which the mounting boss 12A protruding from the middle board 12 is inserted is formed at the lower end of the lower wall portion 32B. After the mounting boss 12A is inserted into the mounting hole 32G, the lower end 32B of the bezel 32 is coupled to the middle board 12 by welding the protruding end of the mounting boss 12A by welding means such as ultrasonic welding. The

  As shown in FIG. 6, the light source 50 includes an LED 51 (light source body) and a light guide body 60. As shown in FIGS. 5 and 6, the light guide 60 includes a lens member 62 having a substantially rectangular plate shape in plan view, an upper cover 61 that houses the LED 51 and the lens member 62 from above and below, and a lower side. The cover 63 is mainly configured. The light guide 60 is for guiding the light emitted from the LED 51 to the light emission holes 32E (and thus in the housing portion 30) and the lower wall light emission holes 32F (and thus the switch base 16). .

  The LED 51 is mounted on the substrate 52 as shown in FIG. An electric wire 53 is connected to the substrate 52. A connector 54 is attached to one end of the electric wire 53, and this connector 54 is electrically connected to a power supply device (not shown).

  The lens member 62 is made of a synthetic resin having high translucency (high transparency) such as acrylic. As shown in FIG. 7, the corner of the lens member 62 on the LED 51 side is notched in a curved shape, and serves as a light incident surface 62A (light incident portion). The LED 51 is arranged such that its light emitting surface 51A faces the light incident surface 62A. Thereby, the light from the LED 51 is incident on the light incident surface 62A.

  The optical axis LA of the LED 51 is arranged along the vehicle front-rear direction (left-right direction in FIG. 7). The light emitted from the LED 51 (light emitting surface 51A) spreads three-dimensionally radially within a predetermined angular range around the optical axis LA, and the light emission intensity is conspicuous in the direction along the optical axis LA. The angle distribution is high and tends to decrease as the tilt angle with respect to the optical axis LA increases.

  The upper cover 61 and the lower cover 63 are made of, for example, synthetic resin. Further, as shown in FIG. 6, recesses 61B and 63B into which the LEDs 51 can be fitted are formed on the inner peripheral surfaces of the covers 61 and 63, and the LEDs 51 are arranged in the recesses 61B and 63B. It has become.

  As shown in FIG. 7, extending portions 61 </ b> D and 61 </ b> E are formed from both sides of the upper cover 61 in the vehicle front-rear direction (left-right direction in FIG. 7), respectively. Attachment holes 61D1 and 61E1 are formed through the extending portions 61D and 61E, respectively. On the lower wall portion 32B of the bezel 32, mounting claws 34D and 34E are formed extending outward from the passenger compartment. The light source 50 is attached to the bezel 32 by fitting the attachment claws 34D and 34E into the attachment holes 61D1 and 61E1.

  The inner peripheral surfaces 61R and 63R of the upper cover 61 and the lower cover 63 are light reflecting surfaces capable of reflecting light, respectively. As a method of forming such a light reflecting surface, for example, the upper cover 61 and the lower cover 63 may be made of a material having a color (white or the like) excellent in light reflectivity. The light reflecting surface may be formed by applying a paint (for example, white paint) having excellent light reflectivity to the inner peripheral surfaces of the upper cover 61 and the lower cover 63.

  As shown in FIG. 6, the front end wall portion 64 (the portion arranged to face the lower wall portion light emission hole 32 </ b> F) of the upper cover 61 toward the vehicle interior side is directed toward the vehicle interior side (side away from the LED 51). It has a shape that is inclined downward, and has a function of reflecting light that has reached the inner surface of the tip wall portion 64 downward.

  As shown in FIG. 7, the end of the lower cover 63 opposite to the side on which the LEDs 51 are arranged is a protruding wall 65 that protrudes rearward of the vehicle. The protruding wall portion 65 is disposed at a position along the optical axis LA of the LED 51 in a plan view, and an upper light emitting portion 62B of the lens member 62 described later is accommodated in a portion surrounded by the protruding wall portion 65. Is done. Further, as shown in FIG. 6, the bottom surface 65 </ b> A of the protruding wall portion 65 has a shape that rises and slopes toward the rear of the vehicle (the side away from the LED 51). Thereby, the light that has reached the bottom surface 65A of the protruding wall portion 65 is reflected upward.

  As shown in FIGS. 4 and 5, in the upper cover 61, a through hole 61 </ b> A is formed at a location facing the light emitting hole 32 </ b> E of the bezel 32, and the lens member 62 is formed from the through hole 61 </ b> A. The upper light emitting portion 62B (light emitting portion) is exposed. In other words, the upper light emission part 62B is arranged in a shape facing the formation position of the light emission hole 32E.

  As shown in FIGS. 4 and 5, in the lower cover 63, a through hole 63 </ b> A is formed at a position facing the lower wall light emission hole 32 </ b> F of the bezel 32, and the lens member 62 is formed from the through hole 63 </ b> A. The lower light emitting portion 62D (light emitting portion) formed on the lower surface (the lower surface of the light guide) is exposed. That is, the lower light emitting portion 62D is arranged in a form facing the formation location of the lower wall portion light emitting hole 32F. In addition, as shown in FIG. 7, the lower wall part light emission hole 32F has comprised the shape extended in the vehicle front-back direction.

  Of the light incident surface 62A, the curved surface 62A1 on the lower light emitting portion 62D side has a shape in which the emitted light from the LED 51 (the light beam L2 in FIG. 7) is diffused over a wide range. On the other hand, of the light incident surface 62A, the curved surface 62A2 on the upper light emitting portion 62B side has a smaller curvature than the curved surface 62A1, and the emitted light from the LED 51 (the light beam L1 in FIG. 7) enters the upper light emitting portion 62B. The shape is directed straight (passing light is not diffused compared to the curved surface 62A1).

  As shown in FIG. 6, the surfaces of the upper surface (light emitting surface) of the upper light emitting portion 62B and the lower surface (light emitting surface) of the lower light emitting portion 62D are formed in a substantially triangular wave shape. This is for adjusting the optical path by refracting the light emitted to the outside of the lens member 62 from the upper light emitting part 62B and the lower light emitting part 62D. The surface shapes of the upper light emitting portion 62B and the lower light emitting portion 62D are not limited to a substantially triangular wave shape, and can be changed as appropriate.

  With the above configuration, the light emitted from the LED 51 enters the lens member 62 from the light incident surface 62A. Part of the light incident on the lens member 62 (the light beam L1 in FIG. 7) reaches the upper light emitting portion 62B and is emitted from the upper light emitting portion 62B. Further, part of the light incident on the lens member 62 (the light beam L2 in FIG. 7) reaches the lower light emitting portion 62D and is emitted from the lower light emitting portion 62D.

  Then, the light L1 emitted from the upper light emitting part 62B passes through the light emitting hole 32E and is emitted into the accommodating part 30. Thereby, the inside of the accommodating part 30 can be illuminated and the visibility of the inside handle 31 can be improved. Further, the light L2 emitted from the lower light emitting part 62D passes through the lower wall light emitting hole 32F and is emitted toward the switch base 16. Thereby, the switch base 16 and the switch operation part provided there can be illuminated, and the visibility can be improved.

  Note that light emitted to the outside of the lens member 62 from locations other than the upper light emitting portion 62B and the lower light emitting portion 62D is reflected by the inner peripheral surfaces (light reflecting surfaces) of the upper cover 61 and the lower cover 63. Then, it enters the lens member 62 again (an example of such light is indicated by a light beam L3 in FIG. 7). Thereby, the utilization efficiency of the light radiate | emitted from LED51 can be made high.

  As shown in FIG. 3 or FIG. 4, the light emission hole 32 </ b> E is arranged on the bottom wall 32 </ b> A of the bezel 32 on the vehicle exterior side (right side in FIG. 4) with respect to the handle portion 31 </ b> A of the inside handle 31. Further, the cover 33 is formed with a protrusion 33A that protrudes toward the vehicle interior side. As shown in FIG. 3, the protrusion 33A is disposed behind the light emission hole 32E (on the left side in FIG. 3). As a result, the protrusion 33A is configured as a light shielding portion capable of shielding the light emitted from the light emission hole 32E to the rear of the vehicle.

  With such a configuration, a part of the light emitted from the light emission hole 32E toward the opening side (the vehicle interior side) in the inside handle housing portion 30 is part of the handle portion 31A and the protrusion of the inside handle 31. The light is blocked by 33A (light blocking portion). In other words, when viewed from the passenger (see line of sight E1 from the passenger in FIGS. 2 and 3), the light emission hole 32E is concealed by the protrusion 33A and the handle portion 31A of the inside handle 31.

  From the above, in the vehicular lighting device 20 of the present embodiment, it is possible to suppress a situation in which a passenger looks directly at the light emission hole 32E (and thus light emitted therefrom). In general, the eyes of the passenger in a seated state are located behind the vehicle from the inside handle housing portion 30. For this reason, in this embodiment, it decided to form the protrusion 33A in the vehicle rear rather than the light emission hole 32E. In order to make it more difficult for the passenger to visually recognize the light emission hole 32E from the rear of the vehicle, it is preferable to form the protrusion 33A closer to the light emission hole 32E.

  In the present embodiment, the light source 50 includes an LED 51, a light incident surface 62A on which light emitted from the LED 51 is incident, and a light guide 60 having a light emitting portion that emits the light. The light emitting portion includes an upper light emitting portion 62B arranged to face the formation position of the light emitting hole 32E in the bottom wall 32A of the bezel 32, and a lower light emitting portion 62D formed on the lower surface of the light guide 60. And have.

  With such a configuration, the light from the LED 51 can illuminate the light guide 60 above (that is, inside the inside handle housing portion 30) and below (in the present embodiment, the switch base 16). That is, in this embodiment, two different places can be illuminated by emitting light upward and downward.

  By the way, in this embodiment, it is set as the structure which illuminates the inside handle accommodating part 30 with the light radiate | emitted upwards from the light source 50. FIG. Thereby, it becomes possible to illuminate places other than the inside handle accommodating part 30 with the light radiate | emitted below. Usually, since the eyes of the seated passenger are positioned above the inside handle housing portion 30, the light emitted upward from the light source 50 is more likely to enter the eyes of the passenger than the light facing downward. In this respect, in the present embodiment, the handle portion 31A and the projection portion 33A of the inside handle 31 can shield such light emitted upward, which is preferable. In other words, in the present embodiment, even when the light emission hole 32E is set on the bottom wall 32A (lower surface) of the inside handle housing portion 30, the passenger emits the light emission hole 32E (and thus light emitted from the light emission hole 32E). ) Can be suppressed.

  In addition, a lower wall portion 32B extending from the end of the bottom wall 32A of the inside handle housing portion 30 so as to cover the side and the lower side of the light source 50 is provided, and the lower wall portion 32B is inclined upward toward the vehicle interior side. It has an inclined portion 32D having a shape. The inclined portion 32D is formed with a lower wall portion light emission hole 32F through which light emitted from the light source 50 can pass.

  The light that has passed through the lower wall light emission hole 32F is suitable for illuminating a predetermined location (the switch base 16 in the present embodiment). And this lower wall part light emission hole 32F is formed in inclination part 32D which inclines and inclines toward the vehicle interior side. In this way, it is possible to suppress the situation in which the passenger visually recognizes the lower wall portion light emission hole 32F from above, so that the design is not impaired (the line of sight E2 of the passenger is shown in FIG. 4).

<Embodiment 2>
Next, a second embodiment of the present invention will be described with reference to FIGS. The same parts as those in the above embodiment are denoted by the same reference numerals, and redundant description is omitted. In the above embodiment, the light emission hole 32E is exemplified as the bottom wall side light guide, and the lower wall light emission hole 32F is exemplified as the lower wall side light guide. On the other hand, in the vehicle lighting device 120 of the present embodiment, the configurations of the bottom wall side light guide unit and the lower wall side light guide unit are different from those of the above embodiment.

  In the present embodiment, the bezel 132 (the bottom wall 132A, the lower wall portion 132B, and the inclined portion 132D) of the inside handle housing portion 130 is made of a highly transparent (highly transparent) synthetic resin material (for example, acrylic or polycarbonate). Is formed. A film 140 is attached to the surface of the bezel 132 on the vehicle interior side.

  The film 140 has a light transmission part 142 and a light blocking part 141. The light transmitting portion 142 is formed on the film 140 at a location facing each of the upper light emitting portion 62B and the lower light emitting portion 62D of the light source 50. In the film 140, a portion other than the light transmitting portion 142 is a light blocking portion 141. In FIG. 8, reference numeral 142 </ b> A is assigned to the light transmission part 142 that faces the upper light emission part 62 </ b> B, and reference numeral 142 </ b> B is assigned to the light transmission part 142 that faces the lower light emission part 62 </ b> D.

  As described above, in the present embodiment, the bezel 132 is made of a highly transmissive member, and the light transmission part 142A (corresponding to the bottom wall side light guide part) and the light transmission part 142B (lower wall part side light guide part). Is provided), it is possible to illuminate the upper part (inside the inside handle housing part 130) and the lower part (switch base 16) of the light source 50.

  An example of the structure of the film 140 having the light transmitting portion 142 and the light blocking portion 141 is shown in FIG. Since the light transmitting portion 142A and the light transmitting portion 142B have the same configuration, only the configuration on the light transmitting portion 142A side is illustrated in FIG. In addition, the structure of the film 140 shown in FIG. 9 shows an example of the film which has the light transmission part 142 and the light shielding part 141, Comprising: It is not limited to this structure.

  As shown in FIG. 9, the film 140 is configured by, for example, laminating a gloss layer 145 and a light shielding layer 146 having a high light shielding property. A hole 143 is formed through the light shielding layer 146 at a location facing the upper light emitting portion 62B (or the lower light emitting portion 62D).

  The gloss layer 145 is formed on the entire surface of the light shielding layer 146 on the vehicle interior side (upper side in FIG. 9). As such a glossy layer 145, for example, a plating coating with a metal or a resin film having a gloss equivalent to that of a metal can be used. In addition, as an example of such a resin film, a product name “PICASUS (trade name)” manufactured by Toray can be cited.

  The gloss layer 145 is set to a thickness that allows light from the light source 50 side to pass therethrough, for example. Thereby, in the film 140, the part corresponding to the hole part 143 is the light transmission part 142, and the other part is the light blocking part 141. By providing such a glossy layer 145, the design can be enhanced. Further, by forming the gloss layer 145 so as to cover the hole portion 143 formed in the light shielding layer 146, the hole portion 143 can be made less noticeable when viewed from the vehicle interior side, and the design is improved. be able to.

<Embodiment 3>
Next, Embodiment 3 of the present invention will be described with reference to FIG. The same parts as those in the above embodiment are denoted by the same reference numerals, and redundant description is omitted. In the vehicle lighting device 220 of the present embodiment, the configuration of the bottom wall side light guide section is different from that of the above embodiment.

  In the second embodiment, the bezel 132 of the inside handle housing portion 130 is a member having high translucency (high transparency). On the other hand, the bezel 232 of the inside handle housing portion 230 in this embodiment is a colored (for example, white) synthetic resin member (for example, ABS resin).
