Description

Technical Field

[0001] This invention relates to two-color molded products, vehicle parts, and vehicle lamps.

Background Art

[0002] In recent years, due to the spread of self-driving vehicles and EVs (electric vehicles), vehicles are required to emit light from vehicle lamps for various purposes. For example, there is an increasing trend in vehicle lamps that emit light in a range from the center of the vehicle to both left and right sides.

[0003] A vehicle lamp includes a lamp lens as a vehicle part, and this lamp lens has a design surface that emits light. The lamp lens having this design surface may be made of, for example, a multilayer molded body shown in Patent Document 1.

[0004] Hereinafter, the multilayer molded body of Patent Document 1 will be described. The multilayer molded body of Patent Document 1 forms a decorative film by printing a desired pattern on a base film, arranges the decorative film in an injection molding die, injects resin into the decorative film, and transfers the pattern to the resin. In the multilayer molded body of Patent Document 1, light emitted from a light source arranged inside is visually recognized through the translucent portion of the pattern transferred to the resin. This pattern becomes the design surface that emits light.

[0005] Also, as a two-color molded product having a design portion, for example, there is the two-color molded product of Patent Document 2. Hereinafter, the two-color molded product of Patent Document 2 will be described. The two-color molded product of Patent Document 2 is composed of a primary molded product having a design portion on at least a part of its surface and a secondary molded product integrally molded with the primary molded product. The design portion is composed of fine irregularities formed by injection molding.

[0007] However, in recent years, the design aspects of vehicles have tended to consist of a variety of colors, patterns, and textures, reflecting the increasing diversification of vehicle designs. Furthermore, two-color molded parts have also tended to have more complex shapes in recent years, due to the increasing diversification of vehicle designs. As a result, it may not always be possible to incorporate a variety of colors, patterns, and textures into the design aspects of two-color molded parts with complex shapes.

[0008] The problem that this invention aims to solve is to provide a two-color molded product, a vehicle part, and a vehicle light fixture that can be given a design surface with a variety of colors, patterns, and textures on a two-color molded product with a complex shape. [Means for solving the problem]

[0009] The two-color molded product, vehicle part, and vehicle lamp according to the first aspect of this invention, in order to solve the above-mentioned problems, comprises a primary molded product made of a light-transmitting material and a secondary molded product made of a light-impermeable material that is joined to the primary molded product so as to surround the periphery of the primary molded product, wherein a design surface is provided on the surface of the primary molded product that faces outward from the vehicle, a part of the structure of the secondary molded product protrudes outward from the vehicle through a groove, and the design surface is formed when ink printed on a carrier film is transferred to the primary molded product during the molding of the primary molded product. [Effects of the Invention]

[0010] The two-color molded products, vehicle parts, and vehicle lighting fixtures of this invention can be given a variety of design features, such as colors, patterns, and textures, on two-color molded products with complex shapes. [Brief explanation of the drawing]

[0012] Hereinafter, an example of an embodiment (example) of the two-color molded product, vehicle part, and vehicle lamp according to the present invention will be described based on the drawings. In this specification, front, rear, upper, lower, left, and right refer to the front, rear, upper, lower, left, and right when the vehicle lamp according to the present invention is installed on a vehicle.

[0013] In the drawings, the symbol "F" represents "front", "B" represents "rear", "U" represents upper, "D" represents "lower", "L" represents "left", and "R" represents "right". Also, in the drawings, the symbol "I" represents the inner side in the vehicle width direction, and the symbol "O" represents the outer side in the vehicle width direction. Further, in the drawings, since they are schematic views, main components are illustrated, illustration of components other than the main components is omitted, and a part of the hatching is omitted.

[0014] (Description of Vehicle VE) FIGS. 1 to 4 show a vehicle VE equipped with vehicle lamps 1L and 1R of the present invention. This vehicle VE mounts the vehicle lamps 1L and 1R on the front part 101 and emits light over a wide range from the center to both left and right sides of the front part 101.

[0015] As shown in FIGS. 1 to 4, the front part 101 is disposed between the upper hood part 102 and the lower bumper part 103. Also, the planar view shape of the front part 101 when viewed from the upper side to the lower side of the vehicle VE has a shape that slopes or wraps from the inner side I in the vehicle width direction to the outer side O in the vehicle width direction. On both left and right sides of the front part of this vehicle VE, above the vehicle lamps 1L and IR, headlamps 104L and 104R are mounted.

[0016] (Description of the Configuration of Vehicle Lamps 1L and 1R) As shown in Figures 1 to 4, the vehicle lights 1L and 1R in this embodiment are attached to the curved sections extending from the center to both the left and right sides of the front front section 101 of the vehicle VE. The right-side vehicle light 1R, which is attached to the right side of the vehicle VE, will be described below. The left-side vehicle light 1L, which is attached to the left side of the vehicle VE, has a configuration that is almost identical to the right-side vehicle light 1R, with the left and right sides reversed. Therefore, the description of the left-side vehicle light 1L will be omitted. In addition, the terms "both left and right sides," "left side," and "right side" will be omitted as appropriate.

[0017] In this example, the vehicle light fixture 1R is a clearance lamp. As shown in Figures 5 and 6, the vehicle light fixture 1R comprises a lamp lens 2, a lamp housing 3, and a light emitting section 4.

[0018] In this example, the lamp lens 2 is the outer lens. The lamp lens 2 is a vehicle part made from a two-color molded product. That is, the secondary molded product in this embodiment is the lamp lens 2. Hereinafter, the vehicle part made from the secondary molded product may be referred to as the lamp lens 2. In this example, the lamp housing 3 is the housing. The lamp housing 3 is a vehicle part made from a light-opaque material, for example, an opaque resin.

[0019] The lamp lens 2 is provided with a mounting projection 20. The lamp housing 3 is provided with a mounting recess 30. The mounting projection 20 of the lamp lens 2 and the mounting recess 30 of the lamp housing 3 are integrally mounted. A space 23 is formed inside the lamp lens 2 and the lamp housing 3. In this example, the space 23 is the lamp chamber. Hereafter, the side with space 23 may be referred to as the inside, and the side opposite to space 23 may be referred to as the outside. Furthermore, this outside is also the outside of the vehicle VE, i.e., the outside of the vehicle.

[0020] The light illuminating unit 4 is located within the space 23. The light illuminating unit 4 irradiates light L1 toward the lamp lens 2. The light illuminating unit 4 includes, for example, a light source and a reflector that reflects the light L1 from the light source toward the lamp lens 2. Alternatively, it includes a light source and a light guide that guides the light L1 from the light source and irradiates it toward the lamp lens 2. Furthermore, the light illuminating unit 4 includes an inner lens and inner housing that form the space, a light source located within the space, and a reflector or light guide. Note that the light illuminating unit 4 may have any configuration other than those described above, as long as it irradiates light L1 toward the lamp lens 2.

[0021] (Description of Lamp Lens 2) In this example, the lamp lens 2 is a vehicle component and consists of a two-color molded product formed in two colors by a two-color injection molding machine. The lamp lens 2 comprises a primary molded product 21 and a secondary molded product 22 that is joined to the primary molded product 21 so as to surround the primary molded product 21.

[0022] As shown in Figures 5 and 6, the lamp lens 2 has a flat portion 210, surrounding wall portions 211 and 220, a first extension wall portion 221, a second extension wall portion 222, a mounting projection 20, and a projection 24. The surrounding wall portions 211 and 220 are integrally provided around the flat portion 210. The flat portion 210 and the surrounding wall portions 211 and 220 are bent at an obtuse angle. The first extension wall portion 221 is integrally provided on the upper part and both left and right sides of the surrounding wall portions 211 and 220, from the front to the rear of the vehicle VE. The surrounding wall portions 211 and 220 and the first extension wall portion 221 are bent at an obtuse angle. The second extension wall portion 222 is the portion enclosed between the solid and dashed lines in Figures 5 and 6, and is integrally provided on the lower part of the surrounding wall portions 211 and 220, from the upper to the lower part of the vehicle VE. The surrounding wall sections 211 and 220 and the second extension wall section 222 are bent at an obtuse angle. Mounting protrusions 20 are integrally provided at the ends of the first extension wall section 221 and the second extension wall section 222, respectively. Protrusion 24 is integrally provided on the front surface of the second extension wall section 222, i.e., the surface shown by the dashed line in Figures 5 and 6, from the rear to the front of the vehicle VE. A recess 25, which is a V-shaped groove, is provided between the protrusion 24 and the lower parts of the surrounding wall sections 211 and 220.

[0023] Thus, the lamp lens 2 has a complex structure and shape due to constraints imposed by its relative relationship with other vehicle parts, in this example, the hood portion 102 and the bumper portion 103. For this reason, with the lamp lens 2 having its current structure and shape, it is extremely difficult to transfer the ink 7 printed on the carrier film 70 (described later) to the outer surface 61 of the primary molded product 21 and form the design surface 6 (hereinafter referred to as film transfer molding) during the molding of the primary molded product 21. Therefore, the lamp lens 2 is made into a two-color molded product consisting of a part with a simple structure and shape that allows for film transfer molding, and a part with a complex structure and shape that makes film transfer molding extremely difficult. The part with a simple structure and shape consists of a structure with small depth and height of irregularities, and is the flat portion 210 and a part of the surrounding wall portion 211 as the primary molded product 21. The parts with complex structures and shapes are those with large depths and heights of indentations and protrusions, and include the remaining peripheral wall portion 220, the first extension wall portion 221, the second extension wall portion 222, the mounting protrusion portion 20, and the protrusion portion 24, which constitute the secondary molded product 22. In particular, the protrusion portion 24, which is provided at the lower part of the peripheral wall portions 211 and 220 via a recess 25, becomes an obstacle when performing film transfer molding.

[0024] The primary molded product 21 is formed by primary molds 510 and 511, as shown in Figures 7 to 10. The primary molded product 21 is made of a light-transmitting material, i.e., a transparent resin. The secondary molded product 22 is formed by secondary molds 520 and 521, as shown in Figures 12 to 14. The secondary molded product 22 is made of a light-impermeable material, i.e., an opaque resin, which in this example is black. The primary molds 510 and 511 and the secondary molds 520 and 521 consist of a movable mold side 510 and 520 and a fixed mold side 511 and 521.

[0025] (Description of primary molded product 21) As shown in Figure 11, the primary molded product 21 has a shallow concave shape that is recessed from the inside to the outside. The concave shape of the primary molded product 21 is not particularly limited. As described above, the primary molded product 21 has a flat portion 210 corresponding to the bottom and a part of the peripheral wall portion 211 integrally provided around the flat portion 210. In this example, the flat portion 210 has a planar shape, but it may also have a curved shape that is curved with a large radius of curvature. The surface shape of the flat portion 210 is not particularly limited.

[0026] The surrounding wall portion 211 is bent at an obtuse angle relative to the flat portion 210. The angle of the bend of the surrounding wall portion 211 is not particularly limited. Thus, the structure of the flat portion 210 and the surrounding wall portion 211 of the primary molded product 21 consists of a structure with small depth and height of irregularities, making it a structure that can be subjected to film transfer molding.

[0027] The end of the surrounding wall portion 211 opposite to the flat portion 210 has a stepped shape. That is, the inner part of the end of the surrounding wall portion 211 is recessed, and the outer part of the end of the surrounding wall portion 211 is protruding.

[0028] The primary molded product 21 has an inner surface 60, an outer surface 61, and a joining surface 62 between the inner surface 60 and the outer surface 61. The secondary molded product 22 is joined to the joining surface 62. The joining surface 62 is a stepped surface along the end surface of the stepped end of the peripheral wall portion 211. That is, the joining surface 620 has a concave surface 620 of the inner recessed portion of the end of the peripheral wall portion 211, a convex surface 621 of the outer convex portion of the end of the peripheral wall portion 211, and a connecting surface 622 between the concave surface 620 and the convex surface 621.

[0029] (Explanation of design surface 6) A design surface 6 is provided on the entire outer surface 61 of the primary molded product 21 that faces outward from the vehicle, excluding the joining surface 62. In this example, the design surface 6 is provided across the entire outer surface 61 of the primary molded product 21 by film transfer molding. That is, the design surface 6 is formed when the ink 7 printed on the carrier film 70 is transferred to the outer surface 61 of the primary molded product 21 during the molding of the primary molded product 21. Note that in Figures 10 to 14, the symbols "6" for printing and "7" for ink are shown together.

[0030] The design surface 6 covers the entire outer surface 61 of the primary molded product 21, and is located on the front, i.e., the front and side surfaces of the primary molded product 21, and extends to the convex surface 621 on the design surface 6 side of the joint surface 62 with the secondary molded product 22. As a result, the end surface 63 of the boundary of the design surface 6 and the convex surface 621 of the joint surface 62 are flush.

[0031] The design surface 6 is formed by transferring ink 7 printed on the carrier film 70 to the outer surface 61 of the primary molded product 21. The ink 7 printed on the carrier film 70 has a design applied to it. The ink 7 consists of a colored film and a light-shielding film. The color of the colored film is the same color system as or nearly the same color system as the exterior paint of the vehicle VE. In this example, the light-shielding film is black. However, the color of the light-shielding film is not limited to black. In this example, the thickness of the ink 7, i.e., the thickness of the design surface 6, is approximately 10 μm.

[0032] The primary molded product 21 and the multiple openings allow light L1 from the light irradiation unit 4 to pass through the primary molded product 21 and through the multiple openings to form an arbitrary pattern, in this example, a light-emitting part LS that is elongated in the left-right direction parallelogram shape, as shown in Figures 2 and 4. Note that the light-emitting part LS may have a shape other than a parallelogram, or may be a separate pattern. This light-emitting part LS forms the design surface 6.

[0033] The emitted light L2, which passes through the primary molded product 21 and through multiple openings, enters the human eye E as a light-emitting part LS, i.e., a light-emitting design surface 6. Furthermore, the emitted light L2 from the lamp lens 2 has a predetermined luminous intensity, that is, in this example, an intensity that satisfies the clearance lamp function.

[0034] (Description of secondary molded product 22) The secondary molded product 22 is integrally joined to the joining surface 62 of the primary molded product 21 so as to surround the primary molded product 21. As described above, the secondary molded product 22 is provided with the remaining peripheral wall portion 220, the first extended wall portion 221, the second extended wall portion 222, the mounting projection portion 20, the projection portion 24, and the recessed portion 25. The projection portion 24 protrudes toward the outside of the vehicle, that is, in the movable directions 512 and 522 of the movable molds 510 and 520. The recessed portion 25 is recessed toward the inside of the vehicle, that is, in the movable directions 512 and 522 of the movable molds 510 and 520.

[0035] Thus, the secondary molded product 22 has a structure in which the protrusions 24 and recesses 25 are large in depth and height, making it impossible to perform film transfer molding. The protrusions 24, which are part of the structure of the secondary molded product 22, protrude outwards from the vehicle by about 40 mm in this example. The protrusions 24 support the bumper portion 103, and the recesses 25 accommodate the upper edge of the bumper portion 103.

[0036] (Description of the operation and effects of the embodiment) The functions and effects of the lamp lens 2 and vehicle lighting fixtures 1L and 1R described above will be explained.

[0037] When the lights are not illuminated, as shown in Figure 5, when ambient light L3, such as natural light, strikes the design surface 6 of the primary molded product 21 of the lamp lens 2 of the vehicle lights 1L and 1R, it is reflected as reflected light L4 by the colored film on the design surface 6. This reflected light L4 has the color of the colored film. Here, the color of the colored film is the same color system as or nearly the same color system as the exterior paint of the vehicle VE. Therefore, the primary molded product 21 of the lamp lens 2 of the vehicle lights 1L and 1R appears to be the same color system as or nearly the same color system as the exterior paint of the vehicle VE, thus camouflaging the vehicle lights 1L and 1R.

[0038] Furthermore, the openings in the colored film and light-shielding film of the design surface 6 are minute, and in this example, they are created by laser ablation or the like. Therefore, the openings are not very noticeable when the lights are off. On the other hand, the secondary molded product 22 of the lamp lens 2 is black and is mostly hidden by the bumper portion 103, so it is not noticeable from the outside of the vehicle VE.

[0039] When the lamp is lit, as shown in Figure 6, a portion of the light L1 from the light irradiating unit 4 passes through the primary molded product 21 of the lamp lens 2 and through the opening in the design surface 6 of the primary molded product 21, and is emitted from the lamp lens 2 as emitted light L2. Then, on the lamp lens 2, an emitter of any pattern, for example, an emitter LS in the shape of a parallelogram that is long in the left-right direction, as shown in Figures 2 and 4, emits light as the design surface 6. Here, since the light L1 irradiated from the light irradiating unit 4 is white light or amber light L1, the emitter LS and the design surface 6 emit light in white or amber.

[0040] Thus, the lamp lens 2 and the vehicle lighting fixtures 1L and 1R have different appearances when they are not lit and when they are lit.

[0041] In this example, the lamp lens 2, a vehicle part made of two-color molded parts, has a primary molded part 21 with a structure having small depths and heights of irregularities, on which a design surface 6 is provided, while the secondary molded part 22 has convex parts 24 and concave parts 25 with large depths and heights of irregularities. As a result, the two-color molded part according to this embodiment can be provided with a design surface 6 of various colors, patterns, textures, etc., on a two-color molded part, i.e., the lamp lens 2, which has a complex structure and shape.

[0042] (Explanation of examples other than the embodiment) This invention is not limited to the embodiments described above.

[0043] In this embodiment, the vehicle lighting fixtures 1L and 1R are described as being used as clearance lamps mounted on the front part 101 of the vehicle VE. However, in this invention, they may be used for purposes other than clearance lamps, for example, as daytime running lamps mounted on the front part 101 of the vehicle VE. They may also be used as tail lamps, stop lamps, or turn signal lamps mounted on the rear part of the vehicle VE. Furthermore, they may be used as decorative lamps or accessory lamps mounted on the sides of the vehicle VE or at any other location. In this embodiment, the front of the primary molded product 21 refers to the front of the vehicle lighting fixtures 1L and 1R mounted on the front section 101 of the vehicle VE. In the case of vehicle lighting fixtures mounted on the rear section of the vehicle VE, it refers to the rear. Furthermore, in the case of vehicle lighting fixtures mounted on the side section of the vehicle VE, it refers to the side, i.e., the left side and the right side.

[0044] In this embodiment, the vehicle lighting fixtures 1L and 1R are described as being used as horizontally elongated clearance lamps. However, in this invention, they may also be used as vertically elongated lamps or diagonally elongated lamps, in addition to horizontally elongated lamps.

[0045] In this embodiment, the lamp lens 2 has a decorative surface 6 covering its entire outer surface 61. However, in this invention, the decorative surface 6 may be provided on the inner surface 60 of the lamp lens 2, or on a part of the outer surface 61 of the lamp lens 2, or on a part of the inner surface 60 of the lamp lens 2.

[0046] In this embodiment, the design surface 6 of the lamp lens 2 emits light through the primary molded product 21 of the lamp lens 2, passing through the colored film of ink 7 and the openings of the light-shielding film, and then being emitted from the primary molded product 21 of the lamp lens 2 by the emitted light L2. However, in this invention, the design surface of the primary molded product 21 of the lamp lens 2 may be a pattern layer formed on the decorative film described in Patent Document 1. This pattern layer has at least a light-transmitting portion and a light-shielding portion of sufficient size to be visible to the naked eye on the base film. Light emitted from a light source placed inside is visible through the light-transmitting portion of the pattern layer transferred to the resin. This pattern layer becomes the design surface that emits light.

[0047] This embodiment describes an example in which a vehicle component is used as a lamp lens 2 made of two-color molded material. However, in this invention, the vehicle component may also be a vehicle component other than the lamp lens 2, for example, a lens portion of a garnish or ornament.

[0048] [Note] The contents described in some of the embodiments above can be understood, for example, as follows:

[0049] (1) Characteristics of lamp lens 2 as a two-color molded product The lamp lens 2, as described above, is a two-color molded product. A primary molded product 21 made of a light-transmitting material, A secondary molded product 22 made of a light-opaque material is bonded to the primary molded product 21 so as to surround the primary molded product 21, Equipped with, Of the primary molded product 21, the surface facing outwards from the vehicle is provided with a design surface 6. A part of the structure 24 of the secondary molded product 22 protrudes toward the outside of the vehicle through a groove 25, The design surface 6 is formed when the ink 7 printed on the carrier film 70 is transferred to the primary molded product 21 during the molding of the primary molded product 21. These are the characteristics (Figures 5, 6, 11-14).

[0050] Thus, the lamp lens 2 as a two-color molded product is divided into a primary molded product 21, which has a structure with small depth and height of irregularities and can be subjected to film transfer molding, and a secondary molded product 22, which has a structure with large depth and height of irregularities and cannot be subjected to film transfer molding. The secondary molded product 22 is joined to the primary molded product 21, and a design surface 6 is provided on the primary molded product 21. As a result, the design surface 6 can be formed on the lamp lens 2 by film transfer molding. Consequently, even lamp lenses 2 with complex structures and shapes can be provided with a design surface 6 that is rich in design features such as diverse colors, patterns, and textures.

[0051] Furthermore, the two-color molded product, lamp lens 2 of this invention, is constructed with a primary molded product 21 made from a light-transmitting material, and a design surface 6 is provided on the surface of the primary molded product 21 that faces outward from the vehicle, i.e., the outer surface 61. As a result, the two-color molded product, lamp lens 2 of this invention can emit light from the design surface 6 by the emitted light L2 that passes through the primary molded product 21 and is emitted from the lamp lens 2.

[0052] Furthermore, in this invention, the two-color molded lamp lens 2 is constructed by joining a secondary molded part 22 to the primary molded part 21 so as to surround the primary molded part 21, and the secondary molded part 22 is made of a light-opaque material. As a result, the two-color molded lamp lens 2 of this invention can prevent light leakage from the secondary molded part 22, and therefore does not interfere with the illumination of the design surface 6 of the primary molded part 21.

[0053] Furthermore, the lamp lens 2, as described above as a two-color molded product, The design surface 6 can be formed when the ink 7 printed on the carrier film 70 is transferred to the primary molded product 21 during the molding of the primary molded product 21 (Figures 7 to 10).

[0054] Thus, in the lamp lens 2, which is a two-color molded product, the design surface 6 is formed on the primary molded product 21, for example, by film transfer molding. As a result, even if the shape of the lamp lens 2, which is a two-color molded product, tends to be complex, it is possible to provide the lamp lens 2 with a design surface 6 that has a variety of colors, patterns, textures, and other designs that would be difficult to achieve with painting or other methods.

[0055] (2) Arrangement range of design surface 6 The lamp lens 2, as described above, is a two-color molded product. The design surface 6 is positioned on the front and side surfaces of the primary molded product 21 and can extend to the joint with the secondary molded product 22 (Figure 11).

[0056] Thus, the lamp lens 2, which is a two-color molded product, has its design surface 6 positioned on the outer surface 61, which is the front and side of the primary molded product 21, and extending to the convex surface 621 of the joining surface 62, which is the joint with the secondary molded product 22. As a result, the lamp lens 2, which is a two-color molded product, can have the end surface 63 of the design surface 6 and the convex surface 621 of the joining surface 62 of the primary molded product 21 flush. In this way, the lamp lens 2, a two-color molded product of this invention, can have its design surface 6 provided over the entire outer surface 61 of the primary molded product 21.

[0057] (3) Relative positional relationship between the design surface 6 and the protruding part 24 which is part of the structure The lamp lens 2, as described above, is a two-color molded product. The structure 24 and the groove 25 allow the bumper portion 103 to be supported.

[0058] In the lamp lens 2, the portion supporting the bumper portion 103 requires large irregularities. Therefore, the region containing such large irregularities is made into a secondary molded product 22 and is constructed separately from the primary molded product 21. As a result, the design surface 6 can be formed during the molding of the primary molded product 21 by transferring the ink 7 printed on the carrier film 70 to the primary molded product 21. Furthermore, the lamp lens 2, as described above as a two-color molded product, The structure 24 of the secondary molded product 22 can be made to protrude beyond the design surface 6 of the primary molded product 21 in the direction toward the outside of the vehicle (Figures 5 to 14). Furthermore, the structure 24 that protrudes beyond the design surface 6 can support the bumper portion 103.

[0059] Thus, in the lamp lens 2, which is a two-color molded product, a protruding portion 24, which is part of the structure of the secondary molded product 22, protrudes outward from the design surface 6 of the primary molded product 21. As a result, the two-color molded product, lamp lens 2 of this invention, can adequately respond to the diversification of vehicle designs in recent years. Moreover, even though the protruding portion 24 of the two-color molded product, lamp lens 2 of this invention protrudes beyond the design surface 6, the design surface 6 can still be provided on the primary molded product 21.

[0060] (4) Vehicle parts The vehicle parts described above may consist of two-color molded products as described in any one of items (1) to (3) above (Figures 5 to 14).

[0061] Thus, the vehicle component of this invention can achieve the same effects as the lamp lens 2, which is a two-color molded product.

[0062] (5) Two-color molded lamp lenses for vehicle lighting fixtures 1L and 1R Vehicle lighting fixtures 1L and 1R are, The lamp lens 2 and lamp housing 3 form space 23, A light irradiation unit 4 is located within the aforementioned space 23 and irradiates light L1 toward the lamp lens 2, Equipped with, The lamp lens 2 can be made of a two-color molded product as described in any one of the above items (1) to (3) (Figures 1 to 6).

[0063] Thus, the vehicle lighting fixtures 1L and 1R can achieve the same effect as the lamp lens 2, which is a two-color molded product. [Explanation of Symbols]
