(Embodiment 1)
FIG. 1 is a vertical cross-sectional view showing a schematic structure of a vehicular lamp in which an extension member as a lamp component according to the first embodiment is used. The vehicular lamp 1 is, for example, a vehicular headlamp device. The vehicle headlamp device includes a pair of headlamp units arranged on the left and right sides in front of the vehicle. Since the pair of headlamp units have substantially the same configuration except that they have a symmetrical structure, FIG. 1 shows the structure of one headlamp unit as the vehicular lamp 1.

  The vehicular lamp 1 includes a lamp body 2 having a front opening and an outer cover 4 that covers the front opening of the lamp body 2. The outer cover 4 is made of, for example, a translucent resin material. The lamp body 2 and the outer cover 4 form a lamp chamber 6. A lamp unit 10 and an extension member 30 as a lamp component are accommodated in the lamp chamber 6.

  The lamp unit 10 is a so-called reflection-type lamp unit, and includes a bracket 12, a light source mounting part 14, a light source 16, a reflector 18, a shade part 20, and a projection lens 22.

  The bracket 12 is a substantially plate-like member formed of a metal material such as aluminum, for example, and is disposed such that the main surface faces the lamp front-rear direction. A light source mounting portion 14 is fixed to the main surface of the bracket 12 on the front side of the lamp. A heat radiation fin 26 is fixed to the main surface of the bracket 12 on the rear side of the lamp. The bracket 12 is supported by the lamp body 2 via the aiming screw 24. The shape of the bracket 12 is not particularly limited to this.

  The light source mounting portion 14 is formed of a metal material such as aluminum, for example, and protrudes from the main surface of the bracket 12 to the front side of the lamp. The light source mounting unit 14 has a light source mounting surface 14a facing upward in the vertical direction. A light source 16 is mounted on the light source mounting surface 14a. The light source 16 is composed of, for example, an LED, and is disposed such that the light emitting surface faces upward in the vertical direction. The light source 16 may be a laser diode, organic or inorganic EL, incandescent bulb, halogen lamp, discharge bulb or the like. The heat generated by the light source 16 is mainly transmitted to the radiation fins 26 via the light source mounting portion 14 and the bracket 12 and radiated to the outside.

  The reflector 18 is disposed above the light source 16 and fixed to the light source mounting unit 14. The reflector 18 has a reflecting surface 18a formed of a part of a spheroid. The reflective surface 18a has a first focal point and a second focal point located on the front side of the lamp relative to the first focal point. The reflector 18 has a positional relationship with the light source 16 such that the light emitting portion of the light source 16 substantially coincides with the first focal point of the reflecting surface 18a.

  The shade unit 20 is disposed on the front side of the lamp of the light source mounting unit 14 and is fixed to the light source mounting unit 14. The shade part 20 has a flat part 20a arranged substantially horizontally, and a curved part 20b curved downward on the front side of the lamp relative to the flat part 20a. The reflector 18 has a positional relationship with the shade portion 20 such that a ridge line 20c formed by the flat surface portion 20a and the curved portion 20b is positioned in the vicinity of the second focal point of the reflecting surface 18a.

  The projection lens 22 is fixed to the tip of the shade part 20. The projection lens 22 is a plano-convex aspheric lens, and projects a light source image formed on the rear focal plane onto the virtual vertical screen in front of the lamp as a reverse image. The projection lens 22 is disposed on the optical axis O of the lamp unit 10 and at a position where the rear focal point substantially coincides with the second focal point of the reflecting surface 18a. The light emitted from the light source 16 is reflected by the reflecting surface 18a and enters the projection lens 22 through the vicinity of the ridgeline 20c. The light incident on the projection lens 22 passes through the outer cover 4 and is irradiated forward of the lamp. A part of the light source light is selectively cut with the ridgeline 20c as a boundary line. Thereby, the light distribution pattern which has the cut-off line corresponding to the shape of the ridgeline 20c is projected ahead of a vehicle.

  The lamp unit 10 of the present embodiment is a projector-type reflection lamp having a reflecting surface shaped based on a spheroid. However, the structure of the lamp unit 10 is not particularly limited, and may be a parabolic reflection lamp having a reflection surface shaped based on a paraboloid of revolution. The lamp unit 10 may be a direct-type lamp or the like. Moreover, the attachment posture of the lamp unit 10 can also be set as appropriate.

  The extension member 30 is an intermediate member disposed between the light source 16 and the outer cover 4. The extension member 30 has an opening 30a, and is arranged so that the opening 30a and the projection lens 22 overlap in the extending direction of the optical axis O. The extension member 30 covers a region between the opening of the lamp body 2 and the outer periphery of the lamp unit 10. Thereby, the internal structure of the vehicle lamp 1 can be hidden. Therefore, the extension member 30 functions as a blindfold member. The extension member 30 is fixed to the lamp body 2 or the outer cover 4 by a fastening member (not shown) such as a screw.

  Next, the structure of the extension member 30 will be described in detail. FIG. 2 is a cross-sectional view showing a schematic structure of the extension member in a state of being mounted on the mounting table. The extension member 30 includes a main body portion 32, a coating 34, and a plurality of leg portions 36.

  The main body portion 32 includes a design portion 38 that is visually recognized from the outside and a non-design portion 40 that is not visually recognized from the outside when the vehicle lamp 1 is assembled to the vehicle (see FIG. 1). The design portion 38 is a portion that mainly covers a region between the opening of the lamp body 2 and the outer periphery of the lamp unit 10. The non-design part 40 is a part that mainly borders the outer periphery of the design part 38.

  The design part 38 includes a translucent member. In the present embodiment, the entire body portion 32 including the design portion 38 and the non-design portion 40 is made of a translucent resin such as an acrylic resin, a polycarbonate resin, a polyetherimide resin, or a polyarylate resin. . The main body 32 is formed by injection molding the above-described resin material. Therefore, the design part 38 itself is a translucent member.

  The extension member 30 is mounted on a predetermined mounting table 90 in a non-assembled state with respect to the vehicular lamp 1 during transport or storage in the manufacturing process. The mounting table 90 is, for example, a transfer conveyor, a storage shelf, or the like. The design portion 38 has a first design surface 42 that faces the mounting table 90 when the extension member 30 is mounted on the mounting table 90. The first design surface 42 constitutes a part of the surface of the translucent member, that is, the design portion 38. More specifically, the first design surface 42 is a surface facing the light source 16 side or the lamp inner side.

  In addition, the design portion 38 has a second design surface 44 that faces away from the first design surface 42. The second design surface 44 is a surface facing the outer cover 4 side or the lamp outer side. As described above, the design portion 38 has translucency. For this reason, the design part 38 is observed not only on the surface facing the lamp outer side, but also on the surface facing the lamp inner side over the surface facing the lamp outer side. Therefore, not only the surface facing the lamp outer side constitutes the design surface (second design surface 44) but also the surface facing the lamp inner side constitutes the design surface (first design surface 42). In addition, the 1st design surface 42 may face the lamp outer side, and the 2nd design surface 44 may face the lamp inner side.

  The first design surface 42 is a portion in which the extension member 30 is placed on the placement table 90 and the distance from the placement table 90 is equal to the non-design portion 40 or closer to the placement table 90 than the non-design portion 40 (hereinafter referred to as the first design surface 42). Then, this portion is appropriately referred to as “proximity portion 42a”). In FIG. 2, it is separated from the mounting table 90 by a shorter distance L2 than the distance L1 from the portion closest to the mounting table 90 to the mounting table 90 in the non-design part 40, that is, more than the non-design part 40. The proximity part 42a located near the mounting table 90 is illustrated.

  The coating 34 is at least partially provided on the first design surface 42. Further, the coating 34 is provided on at least the proximity portion 42 a of the first design surface 42. The coating 34 functions as, for example, a light shielding film for suppressing light leakage of the light source 16 through the extension member 30. Such a coating 34 can be formed by evaporating a metal such as aluminum on the main body 32, for example. Therefore, the coating 34 is a film (metal deposition film) formed by depositing metal on the surface of the main body 32. The coating film 34 functioning as a light shielding film may be formed by other methods such as spraying a light shielding paint on the main body 32. The coating 34 may function as a protective film that protects the first design surface 42. In this case, the coating film 34 may have translucency.

  In at least a partial region of the extension member 30, the coating 34 is not provided on the second design surface 44 of the main body portion 32. Thereby, when observing from the lamp exterior, the main-body part 32 and the 1st design surface 42 of the back side can be visually recognized. Therefore, a novel design can be given to the vehicular lamp 1 and the design can be improved.

  When the extension member 30 is mounted on the mounting table 90, the plurality of leg portions 36 abut against the mounting table 90 and support the main body 32. Each leg portion 36 is connected to the non-design portion 40 at one end, protrudes toward the side facing the first design surface 42, that is, toward the mounting table 90, and the other end contacts the mounting table 90. For example, the leg part 36 has a long shape in which the length in the direction protruding toward the mounting table 90 is longer than the length in the direction perpendicular to the direction.

  The plurality of leg portions 36 support the main body portion 32 such that the first design surface 42 is separated from the mounting table 90 when the extension member 30 is mounted on the mounting table 90. Therefore, naturally, the proximity portion 42 a of the first design surface 42 is also separated from the mounting table 90. The coating 34 provided on the first design surface 42 is also separated from the mounting table 90 by the legs 36. As described above, the leg portion 36 supports the main body portion 32 in a state where the first design surface 42 is separated from the mounting table 90, thereby avoiding contact between the first design surface 42 or the coating 34 and the mounting table 90. can do. As a result, damage to the first design surface 42 or the coating 34 can be suppressed. The leg portion 36 is separated from the main body portion 32 when the extension member 30 is assembled to the vehicle lamp 1.

  That is, when the extension member 30 is mounted on the mounting table 90, the proximity portion 42 a is separated from the mounting table 90 in a state where the leg portion 36 is connected to the main body portion 32, but the leg portion 36 is separated from the main body portion 32. In this state, the proximity portion 42a comes into contact with the mounting table 90.

  Then, the manufacturing method of the extension member 30 is demonstrated in detail. 3A, FIG. 3B, FIG. 4A, FIG. 4B, and FIG. 5 are process diagrams showing the method of manufacturing the extension member according to the first embodiment.

(Molding process)
First, as shown in FIG. 3A, a mold 50 is prepared. The mold 50 includes a core side mold 52 and a cavity side mold 54. The core side mold 52 is brought into contact with the cavity side mold 54. Thereby, a cavity 60 (molding space) corresponding to the shape of the main body 32 is formed between the core side mold 52 and the cavity side mold 54. The mold 50 also has a resin flow path 56 connected to the cavity 60. The resin flow path 56 includes a gate and a runner connected to the cavity 60 via the gate. The resin flow path 56 may include a sprue connected to the runner. The resin flow path 56 is connected to a region in the cavity 60 corresponding to the non-design part 40 of the main body part 32.

  Next, the core side mold 52 and the cavity side mold 54 are heated and maintained at a predetermined temperature. Further, a predetermined resin is heated to a predetermined temperature and melted inside the molding machine (not shown). Subsequently, a nozzle (not shown) of the molding machine is brought into contact with the mold 50, and the molten resin 31 is injected into the mold 50. The molten resin 31 is injected from the resin flow path 56 into the cavity 60.

  After the elapse of the predetermined time, the molten resin 31 spreads over the entire cavity 60 as shown in FIG. In the process in which the molten resin 31 spreads into the cavity 60, the gas in the cavity 60 is discharged from an exhaust passage (not shown). Thereafter, the molten resin 31 injected into the cavity 60 is cooled to obtain the main body portion 32. Further, the molten resin 31 remains in the resin flow path 56. The remaining molten resin 31 is cooled to obtain a plurality of leg portions 36. Therefore, the main body portion 32 and the leg portion 36 are injection molded products.

(Installation process)
Next, as shown in FIG. 4A, the mold 50 is opened, and the integrally formed product 46 of the main body portion 32 and the leg portion 36 is removed from the mold 50. Then, the removed integrally molded product 46 is mounted on the mounting table 90. At this time, the integrally molded product 46 is mounted on the mounting table 90 such that the leg portion 36 abuts on the mounting table 90. The main body 32 is supported by the legs 36 in a state of being separated from the mounting table 90. The first design surface 42 of the design portion 38 faces the mounting table 90 in a state where the integrally molded product 46 is mounted on the mounting table 90. The proximity portion 42 a closer to the mounting table 90 than the non-designed portion 40 on the first design surface 42 is separated from the mounting table 90 by the plurality of leg portions 36. The integrally molded product 46 before the coating 34 is provided is also included in the “lamp component” of the present application.

  Thereafter, the integrally molded product 46 is transported to the processing chamber of the next process while being placed on the mounting table 90. The next process is, for example, a blow process for removing dust adhering to the surface of the integrally molded product 46. And after performing the blow process to the integrally molded product 46, it mounts on the mounting base 90, and also conveys it to the process chamber of the following process. The process following the blow process is a process for forming the coating 34. As shown in FIG. 4B, the coating 34 is formed in a predetermined region of the main body 32 by the formation process of the coating 34. The extension member 30 is obtained by the above process. The extension member 30 is stored in a state of being mounted on the mounting table 90.

(Leg removal process)
As shown in FIG. 5, the leg portion 36 is removed from the main body portion 32 in assembling the vehicle lamp 1. As described above, the leg portion 36 is made of the resin remaining in the resin flow path 56. Further, the gate, which is a connection portion between the cavity 60 and the runner, has a narrow flow path width. Therefore, the connection part between the main body part 32 and the leg part 36 is thin. For this reason, the leg part 36 can be easily detached from the main body part 32. The extension member 30 from which the leg portion 36 has been removed is fixed to the lamp body 2 or the outer cover 4 as shown in FIG. Thereby, the vehicle lamp 1 is obtained.

  Note that the extension member 30 may not include the coating 34. In this case, the extension member 30 composed of the main body portion 32 and the leg portion 36 is transported and stored in a state of being placed on the placement table 90.

  As described above, the extension member 30 as the lamp component according to the present embodiment includes the design portion 38 that is visible from the outside and the non-design portion that is not visible from the outside when the vehicle lamp 1 is assembled to the vehicle. And a plurality of leg portions 36 that come into contact with the mounting table 90 when the extension member 30 is mounted on the mounting table 90 before being assembled to the vehicular lamp 1. In addition, the design portion 38 has a first design surface 42 that faces the mounting table 90. The first design surface 42 has a proximity portion 42a in which the distance L2 from the mounting table 90 is equal to the distance L1 from the mounting table 90 of the non-design part 40 or shorter than the distance L1. The plurality of leg portions 36 support the main body portion 32 so that the entire first design surface 42 is separated from the mounting table 90.

  The extension member 30 has a proximity portion 42 a that is at the same distance as the non-design portion 40 or closer to the mounting table 90 than the non-design portion 40. For this reason, if the extension member 30 is placed on the mounting table 90 without providing the legs 36, the proximity portion 42a may come into contact with the mounting table 90, and the proximity portion 42a may be damaged. Further, since the extension member 30 includes the coating 34 on the first design surface 42, the coating 34 may be peeled off. On the other hand, by supporting the main body portion 32 by the leg portion 36, contact between the proximity portion 42a and the mounting table 90 can be avoided. Therefore, damage to the proximity portion 42a and the coating 34 can be avoided. Thereby, the appearance defect of the extension member 30 can be reduced. As a result, the appearance of the vehicular lamp 1 on which the extension member 30 is mounted can be improved.

  Moreover, the design part 38 contains a translucent member. Therefore, the design part 38 can visually recognize not only the surface facing the lamp outer side but also the surface facing the lamp inner side from the outside. For this reason, the design portion 38 has a first design surface 42 and a second design surface 44 facing away from the first design surface 42. Since both surfaces of the design portion 38 constitute a design surface, when the extension member 30 is placed on the placement table 90, at least one design surface faces the placement table 90. In the extension member 30 having such a structure, it is possible to enjoy a further effect of reducing the appearance defect by installing the leg portion 36.

  The extension member 30 includes a coating 34 on the first design surface 42. The coating 34 functions as, for example, a light shielding film. Thereby, the light-transmitting main body 32 can be visually recognized from the outside of the lamp while preventing light from the light source 16 from leaking to the outside of the lamp. Therefore, a novel design can be given to the vehicular lamp 1 and the design can be improved.

  Further, the main body portion 32 and the leg portion 36 are injection molded products, and the leg portion 36 is made of a resin remaining in the resin flow path 56 of the mold 50. Thereby, the increase in the number of manufacturing processes by providing the leg part 36 in the extension member 30 can be suppressed. Moreover, the increase in the usage-amount of resin by providing the leg part 36 can be suppressed.

  In addition, the method of manufacturing the extension member 30 according to the present embodiment includes a step of forming the extension member 30 including the main body portion 32 and the leg portion 36 and a step of mounting the formed extension member 30 on the mounting table 90. Including. In the placement process, the plurality of leg portions 36 support the main body portion 32 so that the first design surface 42 is separated from the placement table 90. Thereby, the appearance defect of the extension member 30 can be reduced, and the appearance of the vehicular lamp 1 can be improved.

  Further, the method for manufacturing the extension member 30 according to the present embodiment includes a step of removing the leg portion 36 from the main body portion 32. Thereby, the freedom degree of the installation position of the leg part 36 can be raised. That is, when the extension member 30 is mounted on the vehicular lamp 1, the leg portion 36 can be installed at a position where the main body portion 32 can be stably supported without considering that the leg portion 36 interferes with other members. it can. The leg portion 36 is connected to the non-design portion 40 of the main body portion 32. For this reason, it can be avoided that the separation marks of the leg portions 36 are visually recognized from the outside.
