Description

  The present invention relates to a vehicle decorative part and a vehicle lining, and more particularly, to a vehicle decorative part and a vehicle lining that have a design function as a decorative part and exhibit a practical function.

  Decorative parts for vehicles such as decorative parts used for linings for vehicles are already known, and some of them function as decorative lighting when the passenger compartment becomes dark, such as at night. As an example of a vehicle decorative part having an illumination function as described above, a decorative lighting part attached to a vehicle door lining or a vehicle roof lining is known (for example, see Patent Document 1).

The illumination device for a vehicle described in Patent Document 1 has a desired design on the inner surface of the vehicle, a light shielding region that shields light from the opposite surface inside the vehicle, and transmits light from the opposite surface inside the vehicle. An interior panel in the vehicle is formed by a light transmissive panel in which design portions in which light transmissive areas are alternately arranged are arranged on the surface, and a light source is provided inside the light transmissive panel.
With the above configuration, during the daytime, external light is incident on the light-transmitting panel, and the incident light is reflected by the design print layer applied to the light shielding area, so that the design of the design print layer can be seen from inside the vehicle. On the other hand, at night, when the light source is turned on, the light enters from the back side of the light-transmitting panel, and the light that enters the light shielding area out of this incident light is shielded and does not enter the design print layer. Therefore, although the design cannot be seen from the inside of the vehicle, the light that has entered the light transmission region is transmitted to the surface side of the light transmissive panel, and thus functions as decorative lighting for illuminating the interior of the vehicle that has become dark.

JP 2004-90897 A

By the way, in a decorative lighting component like patent document 1, as a decoration laminated body on the surface inside a vehicle of a light transmissive panel, the permeation | transmission part which permeate | transmits the light which permeate | transmitted the light transmissive panel, and light is interrupted | blocked. A configuration in which a light-shielding layer formed from the light-shielding portion and a design layer arranged in accordance with the surface shape of the light-transmitting panel and disposed on the inner side of the light-shielding layer is conceivable.
With the above configuration, the vehicle lining equipped with this decorative lighting component will be decorated with a design such as a metallic or woodgrain effect applied as a design layer in the daytime, and at night it was irradiated from a light source. The light can be seen through the design layer through the transmissive part, so that it is decorated with a lighted design that looks different from the daytime.

However, in the configuration of the decorative lighting component, in order to improve the function of the decorative lighting, the design layer is formed as thin as possible in order to increase the transmittance of light irradiated from the light source toward the vehicle interior. However, if the thickness of the design layer is reduced, the boundary between the light-shielding part and the light-transmitting part of the light-shielding layer can be seen through from the inside of the vehicle when no light is emitted. In this case, the passenger feels uncomfortable and the design is impaired.
Therefore, there has been a demand for a decorative part for a vehicle that improves the functionality of decorative lighting and enhances the texture of the decorative lighting area and has a design.

In addition, in the configuration of this decorative lighting component, when it is attached to a vehicle lining having a three-dimensional curved shape, the light transmissive panel itself also has a curved shape. When the design layers are laminated by the processing, the design layers are locally stretched and the film thickness is locally thinned. As a result, the luminance uniformity of surface emission may be impaired.
Therefore, there has been a demand for a decorative part for a vehicle that has improved luminance uniformity in the decorative lighting area.

The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a vehicle decorative part and a vehicle lining that improve the functionality of light emitting illumination and improve the texture of the light emitting region. It is to provide.
Another object of the present invention is to provide a vehicular decorative part and a vehicular lining that have improved luminance uniformity in a light emitting region.

  According to the vehicle decorative component of the present invention, the object is a vehicle decorative component that is installed in a vehicle and has a light emitting region that emits light, and irradiates light toward the front of the light emitting region. And a transmission body that transmits light emitted from the irradiation body at a position in front of the irradiation body, and a light beam that is formed at a position in front of the transmission body with the surface exposed, and is transmitted through the transmission body. A decorative body, and the decorative body is arranged in a region adjacent to the transmissive portion for transmitting the light transmitted through the transmissive body, and blocks the light transmitted through the transmissive body. A light-shielding layer formed from a laminated body comprising a light-shielding layer formed from the light-shielding layer and a design layer formed in front of the light-shielding layer, the color tone of the transmissive body, and the light-shielding layer of the decorative body Of these, the color tone of the light-shielding portion is set to a similar color.

As described above, the color tone of the transmissive body that constitutes the light emitting region of the decorative component for vehicle and the color tone of the light shielding portion in the light shielding layer of the decorative body stacked in front of the transmissive body have the same color. Therefore, when the occupant looks at the light emitting region from the inside of the vehicle, it can be suppressed that the boundary line between the light shielding portion and the light transmitting portion adjacent to the light shielding portion is seen through in the light shielding layer.
Specifically, the light-shielding portion constituting the light-shielding layer is usually colored black by the surface treatment, and the transmission portion is composed of a transparent color. In some cases, the boundary line between the black light-shielding portion and the transparent body made of a normal white resin that can be seen through the transparent transmission portion may be seen through. This is because in order to ensure the brightness of the light-emitting illumination, it is necessary to usually reduce the thickness of the design layer. At this time, in order to reduce the difference in color tone between the black light-shielding portion and the white transmissive body, the boundary line can be blurred by making the color tone of the light-shielding portion and the color tone of the transmissive body similar colors. it can.
Therefore, it is possible to provide a vehicle decorative component that improves the texture of the light emitting region while improving the functionality of the light emitting illumination.

At this time, the said decorating body is a decorating film affixed on the said transparent body, Comprising: The said design layer of this decorating film is good to provide the metal layer which consists of a metal thin film.
As described above, since the design layer constituting the decorative film includes a metal layer made of a metal thin film, the vehicle decorative component is attached to a vehicle lining having, for example, a three-dimensional curved shape, and a transparent body. Even if the shape itself is curved, even if the decorative film is distorted by making the metal layer that makes up the decorative film a thin film, changes in the thickness of the metal layer can be minimized. This makes it easy to ensure luminance uniformity in the light emitting area.
More specifically, when a metal layer is laminated on the surface of a transparent body having a curved shape, for example, by a printing process, the metal layer is locally stretched, and the film thickness is locally reduced or increased. Therefore, the light transmittance of the metal layer is affected, and the luminance uniformity of surface emission may be impaired. On the other hand, if the thickness of the metal layer is reduced, the boundary line between the light shielding portion and the transmissive portion constituting the light shielding layer can be seen through from the vehicle interior when no light is emitted, which may impair the design. there were. Therefore, first, the design can be ensured by concealing the boundary line by using the color tone of the light-shielding portion and the color tone of the transparent body seen through the transparent transmission portion as similar colors. And, by forming the metal layer from a metal thin film and making the film thickness relatively small, the influence on the uniformity of the film thickness of the metal layer can be made relatively small when the metal layer is laminated, Has a synergistic effect. In addition, cost also falls by using a metal thin film.

At this time, the transmission body is formed of a resin material, and the mixing ratio of the black pigment is preferably 1 or less when the amount of the resin material constituting the transmission body is 100.
With the above configuration, the transmissive body is formed as a resin material composed of a gray color similar to black. Therefore, the color tone of the light-shielding part and the color tone of the transmission body are made similar to black, thereby improving the texture of the light emitting region and adjusting the blending ratio of the black pigment to relatively increase the light transmittance of the transmission body. The luminance of the light emitting region can be ensured by maintaining the above.

At this time, the light-shielding portion is colored in white or a similar color to white by any one surface treatment selected from the group including printing, painting, vapor deposition, plating, or transfer, and the transmission body is white or It may be formed from a resin material having the same color as white.
With the above configuration, the color tone of the light-shielding portion and the color tone of the transmission body can be made white or similar to white. As a result, when viewed from the inside of the vehicle, the boundary line between the light shielding portion and the transparent body that can be seen through the transparent transmission portion can be hidden via the design layer, and the texture of the light emitting region can be enhanced. The light-shielding portion is usually colored black and absorbs light to provide light-shielding properties. However, the light-shielding portion is also configured to have light-shielding properties by coloring white and reflecting light. In addition, the light reflectance can be increased in the light shielding portion, and the light emission efficiency can be increased.

At this time, the light-shielding part may be colored by surface treatment so that the surface concentration increases as the distance from the light-transmitting part increases from the adjacent light-transmitting part side toward the light-shielding part side.
With the above configuration, the boundary line between the light shielding portion and the transmission portion can be further blurred by gradation processing. As a result, when viewed from the inside of the vehicle, the boundary line between the light shielding part and the transparent body that can be seen through the transparent transmission part can be further hidden through the design layer, and the texture of the light emitting region can be enhanced. At the same time, the design can be improved by blurring the light emission.

At this time, the light shielding layer of the decorative body is preferably formed by laminating at least two layers by surface treatment.
With the above-described configuration, it is possible to suppress the occurrence of pinholes when a light shielding layer is stacked and arranged as a decorative body on a transmission body, and the texture of the light emitting region can be enhanced.

Further, a pull pocket is formed between the door base 4 and the front end portion of the door armrest 3 in the range indicated by the symbol T4 in FIG. Yes.

<Outline of luminous ornament 1>
Next, the outline of the light emitting ornament 1 will be described with reference to FIGS. 2A and 2B.
The light-emitting ornament 1 is a decorative component for vehicle door lining that is attached to a portion of the vehicle interior of the door base 4 that is aligned with the pull handle 5. The light-emitting ornament 1 functions as a lighting device in the vehicle door lining R, and lights up when the passenger compartment becomes dark, such as at night. With the illumination function of the light emitting ornament 1, for example, when the door is open, it is possible to notify the rear vehicle or a person that the vehicle is in the door open state.

When the light emitting ornament 1 performs the illumination function, only the lower part of the light emitting ornament 1 emits light, and the upper part of the light emitting ornament 1 does not emit light.
Specifically, as shown in FIG. 2A, the light emitting ornament 1 has a knife-like outer shape that is long along the front-rear direction of the vehicle, and the lower end thereof is located at a position slightly rearward of the front end. A light emitting region 1a is formed in a substantially triangular shape. A light source is disposed outside the light emitting area 1a. When the light source is turned on, the light emitting area 1a emits light with a predetermined luminance.

  On the other hand, a non-light emitting region 1b that does not emit light is formed in a portion of the light emitting ornament 1 excluding the light emitting region 1a. The non-light emitting region 1b is adjacent to the light emitting region 1a on the upper side of the light emitting region 1a, and does not emit light even when the light source of the light emitting ornament 1 is turned on.

Further, the light emitting ornament 1 functions as a decorative part for improving the design of the door in a situation where a lighting function is not required, such as daytime. And in the light emission ornament 1, the light emission area | region 1a of the state which is not light-emitting is the same wearing as the non-light emission area | region 1b. That is, the decoration style of the inner surface of the light emitting area 1a is the same as the decoration style of the inner surface of the non-light emitting area 1b, and specifically, the surface is colored metallic.
Here, the decoration style means visual characteristics that appear due to a decoration process applied to the surface, such as a surface color scheme, pattern, gloss, texture, and the like.

As described above, the decoration style of the interior surface of the light emitting area 1a is the same as the decoration style of the interior surface of the non-light emitting area 1b. Will be improved.
That is, the light-emitting ornament 1 hides the presence of the light-emitting area 1a by emphasizing the design of the door when the lighting function such as daytime is not required, and is illustrated in FIG. 2B when the lighting function such as nighttime is required. As described above, the illumination function can be effectively exhibited by causing the light emitting region 1a to emit light. Such a property is called stealth property, and in the light-emitting ornament 1 according to the present embodiment, the stealth property is greatly improved as compared with the conventional vehicle lighting device.

  Note that, as described above, in the present embodiment, the vehicle interior surfaces of both the light emitting area 1a and the non-light emitting area 1b are colored in a metallic tone. Other than that, it is good also as a color scheme and a pattern being the same.

<Configuration of luminous ornament 1>
Next, the configuration of the light emitting ornament 1 will be described in detail with reference to the drawings.
As shown in FIG. 3, the light emitting ornament 1 has an ornament unit 10 and a light source unit 30 as main components.
The ornament unit 10 is a plate-like member exposed to the inside of the vehicle. That is, the ornament unit 10 defines the outer shape of the light-emitting ornament 1 and is located inside the vehicle so as to express the decoration of the light-emitting ornament 1.

The ornament unit 10 corresponds to a decoration unit, and has a portion that emits light when the light source of the light emitting ornament 1 is turned on, and a portion that does not emit light.
The portion of the ornament unit 10 that does not emit light is the non-light emitting region 1b.
On the other hand, in the ornament unit 10, the light-emitting area 10a, which is a light emitting part, is a part of the light emitting area 1a, and corresponds to a part of the light emitting area 1a excluding the light source unit 30.
As described above, in the present embodiment, the non-light emitting area 1b and the light emitting area 10a are integrated as the ornament unit 10.

The ornament unit 10 is fixed to the inner surface of the door base 4.
For fixing the ornament unit 10 to the door base 4, both a fixing method by screwing and a fixing method by snap-fit engagement are used.

  The light source unit 30 corresponds to an irradiation body, and includes a lamp 31 as a light source and a light guide body 32 having an emission surface 32 a that emits light from the lamp 31. Has been placed. That is, the light source unit 30 is disposed at a position sandwiched between the door base 4 corresponding to the base member and the ornament unit 10 corresponding to the decorating unit.

If it demonstrates concretely, the light source unit 30 will be assembled | attached to the surface which is the vehicle outer side of the light emission area | region 10a among the ornament units 10, and opposes the door base 4. FIG.
In addition, the fixing method by snap-fit engagement is used for the assembly of the light source unit 30 to the light emitting region 10a.

Thus, since the light source unit 30 is disposed at a position sandwiched between the door base 4 and the ornament unit 10, the light source unit 30 can be made compact in a limited space such as the interior of the vehicle door. Can be placed. As a result, the concealment of the lamp 31 provided as the light source in the light source unit 30 can be effectively realized, so that the stealth property indicating the property of concealing the presence of the light emitting region 1a is improved in a situation where an illumination function such as daytime is not required.
Hereinafter, each of the ornament unit 10 and the light source unit 30 will be described in more detail.

<Configuration of ornament unit 10>
As shown in FIGS. 3 and 4, the ornament unit 10 includes a light-emitting region 10 a and a non-light-emitting region 1 b. Each of the light-emitting area 10 a and the non-light-emitting area 1 b includes an ornament base material 11 made of a resin material, and a decorative film 12 attached in accordance with the surface shape on the vehicle interior side of the ornament base material 11.

  Both the light-emitting area 10a and the non-light-emitting area 1b have a laminated structure as shown in FIG. 5 and have a structure in which a decorative film 12 is attached to the surface of the ornament base material 11. On the surface of the ornament base material 11, an adhesive layer 12 f applied for attaching the design layer 12 a constituting the decorative film 12 and the light shielding layer 12 c is formed.

The ornament substrate 11 is a member corresponding to a transmissive body, and is formed as a gray resin-molded product by adding a black pigment to a translucent white resin material.
As the resin material of the ornament substrate 11, acrylonitrile butadiene styrene resin (ABS), polycarbonate resin (PC), polymethyl methacrylate resin (PMMA), and the like can be used. As a material of the ornament base material 11, a material considered suitable in consideration of heat resistance, chemical resistance, impact resistance, combustion resistance, and the like may be selected. In this embodiment, a PC resin is used. .
When the blending amount of the PC resin material constituting the ornament base material 11 is 100, the blending ratio of the black pigment is preferably set to 1 or less. With the above configuration, the ornament base material 11 is formed as a resin molded product made of a gray color similar to black, and the desired luminance of the light-emitting region 10a can be secured while maintaining the light transmittance relatively high.

As shown in FIG. 3, the ornament base 11 that forms the light-emitting region 10 a has a configuration in which the light source unit 30 is disposed on the vehicle exterior side, and transmits light from the light source unit 30.
The ornament base material 11 contains a light diffusing material, and the light passing through the ornament base material 11 is diffused. As a result, when the lamp 31 included in the light source unit 30 is turned on, the light is diffused and transmitted through the ornament base material 11 forming the light-emitting region 10a, so that the entire light-emitting region 10a can emit light. A known light diffusing agent can be used as the light diffusing material.

  In the present embodiment, the ornament base material 11 forming the light-emitting region 10a and the ornament base material 11 forming the non-light-emitting region 1b are integrally formed. However, the present invention is not limited to this, and the light-emitting region 10a is not limited thereto. The ornament base material 11 forming the non-light emitting region 1b and the ornament base material 11 forming the non-light emitting region 1b may be individually molded.

The decorating film 12 is a member corresponding to a decorating body, is located on the innermost side of the ornament unit 10 and imparts decorating properties to the ornament unit 10.
The decorative film 12 is formed by laminating a light-shielding layer 12c and a design layer 12a in order by surface treatment on a colorless and transparent film substrate made of PMMA resin or polyethylene terephthalate resin (PET). It is a film having optical properties.

The design layer 12a constituting the decorative film 12 is a portion that imparts decorative properties to the ornament unit 10, and as shown in FIGS. 5 and 6A, a metal layer made of a metal thin film formed by a vacuum deposition process. 12b is provided. As a result, the interior surface side of the ornament unit 10 is colored so as to exhibit a metallic texture.
The metal layer 12b constituting the design layer 12a is made of a metal thin film of about 10 to 100 nm, has a light reflectance of about 90%, and has a light transmittance of about 10%.
As a result, in the daytime, external light is reflected by the design layer 12a, so that the light-emitting ornament 1 is decorated with a metallic design applied to the design layer 12a. Further, at night, the light emitted from the light source unit 30 passes through the ornament base material 11 and the decorative film 12 and can be seen through the metallic design of the design layer 12a, so that the light emitting ornament 1 can be seen in the daytime. Will be decorated with an unusually illuminated design.

The design layer 12a will be described in detail. As shown in FIG. 5, the metal layer 12b, a tint layer that imparts a metal texture, and a hairline printed layer that imparts a metal hairline texture, in order from the ornament substrate 11 side, A UV hard coat layer or a protective film that forms surface physical properties is laminated and formed.
The tint layer is composed of a silver colored layer of about 1 to 10 μm, and is formed by a tint process, that is, a process of adding a dye to give a thin color. The hairline printing layer is composed of a hairline pattern layer of about 1 to 10 μm, and is formed by a hairline printing process. The UV hard coat layer or the protective film has a thickness of about 3 to 30 μm and is formed for the purpose of increasing the film strength of the decorative film 12 and preventing scratches or peeling.

As shown in FIG. 5, the light shielding layer 12c constituting the decorative film 12 is disposed in a light shielding portion 12d that shields light emitted from the light source unit 30 toward the vehicle interior, and a region adjacent to the light shielding portion 12d. , And a transmission part 12e that transmits light.
The light shielding layer 12c is formed on the surface side of the ornament base material 11 by a printing process such as gravure printing. At this time, the light shielding layer 12c is formed by laminating at least two layers by a printing process, thereby suppressing the occurrence of pinholes.

As shown in FIG. 6B, the light shielding portion 12d is a portion corresponding to the non-light emitting region 1b in the light shielding layer 12c, and black ink is solid-printed on the surface side of the ornament base material 11 by a printing process. And is colored black or a similar color to black.
The portion where the black ink is solid-printed as the light shielding portion 12d does not have translucency, and blocks light transmitted through the ornament substrate 11. As a result, the non-light emitting region 1b does not emit light while the light emitting ornament 1 emits light.

The transmission part 12e is a part corresponding to the light-emitting region 10a in the light shielding layer 12c, and is formed such that the central part is extracted in a substantially elliptical shape.
In the configuration in which the transmission part 12e is transparent, the transparent includes not only colorless and transparent, but also translucent with a slightly translucent translucent color.

With the above configuration, the light shielding layer 12c has a configuration in which a light shielding portion 12d coated with black ink and a transparent portion 12e with a transparent color not coated with black ink are mixed.
At this time, as shown in FIGS. 6A and 6B, when the ornament unit 10 covered with the decorative film 12 is viewed from the inside of the vehicle when no light is emitted, the boundary line between the light shielding portion 12d and the transmission portion 12e is hidden. As a result, the texture of the light emitting region is enhanced.
Specifically, the light-shielding portion 12d is colored black or the same color as black by a printing process, and the ornament base material 11 is colored gray by adding a black pigment to a white resin material, The color tone of the light shielding part 12d and the color tone of the ornament base material 11 are similar colors. As a result, when viewed from the inside of the vehicle, as shown in FIGS. 6A and 6B, the boundary line between the light shielding portion 12d and the ornament base material 11 visible through the transparent transmitting portion 12e is hidden through the design layer 12a. And the texture of the light emitting area is enhanced.

Further, in order to blur the boundary line between the transmissive part 12e and the light shielding part 12d and to blur the light emitted from the ornament unit 10, the structure gradually transitions from the transmissive part 12e toward the light shielding part 12d. The print density of the light-shielding part 12d is preferably provided with gradation so that the print density increases as the distance from the transmission part 12e increases.
By doing in this way, the boundary line of the transmission part 12e and the light-shielding part 12d can be concealed, the texture of the light-emitting area of the light-emitting ornament 1 can be further enhanced, and the light-emitting illumination can be made blurry, and the design property can be improved. improves.

  In the said structure, in the light-shielding part 12d of the decorating film 12, the light which permeate | transmitted the ornament base material 11 cannot permeate | transmit, but the light which permeate | transmitted the ornament base material 11 permeate | transmits only by the permeation | transmission part 12e. As a result, while the light emitting ornament 1 emits light, only the portion of the decorative film 12 where the transmitting portion 12e is located emits light. Thereby, it becomes possible to light-emit only the predetermined part among the light emission area | regions 1a, and the decoration property which the illumination effect of the light emission ornament 1 brings is improved.

  In addition, when the light from the light source unit 30 is irradiated toward the ornament unit 10, the light passes through the ornament base material 11 containing the light-diffusing material. As a result, the irradiation range of the light irradiated from the ornament unit 10 is widened, and compared with the case where no light-diffusing material is contained, the irradiation luminance is substantially in the irradiation range while illuminating a wide area centering on the light emitting ornament 1. It becomes uniform and can provide a good lighting effect.

As described above, in the present embodiment, a decorative body is formed on the surface of the ornament base material 11 by attaching the decorative film 12 to the surface of the ornament base material 11. However, the method of forming the decorative body on the surface of the ornament base material 11 is not limited to this. For example, the vapor deposition treatment or mirror ink coating is performed directly on the resin surface of the ornament base material 11. May be.
Note that it is preferable that the design layer 12a is formed by attaching the decorative film 12 in that the light transmitting portion 12e and the light shielding portion 12d can be freely arranged.

On the other hand, as shown in FIG. 4, a boss 13 and an engaging protrusion 14 for fixing the ornament unit 10 to the door base 4 are formed on the back side of the ornament unit 10.
The boss 13 is a portion that fits into a boss hole 4a formed at a corresponding position on the door base 4 and is fixed with a screw in such a state.
The engagement protrusion 14 is a portion that fits into a fitting hole 4 b formed at a corresponding position in the door base 4 and is snap-fit coupled to the door base 4.
The boss 13 and the engagement protrusion 14 correspond to a decoration unit side fixing portion, and extend from the outer surface of the ornament unit 10.

  Further, the boss 13 and the engagement protrusion 14 are provided in a region where the light emitting region 10a is removed from the ornament unit 10, and are provided at both ends in the longitudinal direction of the ornament unit 10 as shown in FIG. Since the boss 13 and the engagement protrusion 14 are thus provided in the non-light emitting area 1b, the ornament unit 10 can be attached and fixed to the door base 4 so as not to interfere with the light irradiation from the light emitting area 10a. I can do it.

Further, as shown in FIG. 4, ribs 15 are erected on the rear surface of the ornament unit 10 outside the vehicle. The rib 15 is provided to ensure the rigidity of the ornament unit 10, extends from the back surface of the ornament unit 10, and is endless so as to form a substantially trapezoidal outline when the back surface of the ornament unit 10 is viewed from the front. Is formed.
The rib 15 surrounds the light source unit 30 when the light source unit 30 is assembled to the ornament unit 10. Thereby, it becomes possible to arrange the light source unit 30 more compactly in a limited space such as the inside of the vehicle door.

<Configuration of light source unit 30>
The light source unit 30 constitutes the light emitting area 1 a of the light emitting ornament 1 together with the ornament base material 11 and the decorative film 12 constituting the light emitting area 10 a of the ornament unit 10.
As shown in FIG. 7, the light source unit 30 includes a lamp 31 and a light guide 32 including an emission surface 32 a that emits light from the lamp 31.
The lamp 31 and the light guide 32 are held by a holder 33 and integrated as a light source unit 30 via the holder 33.

The light source unit 30 is located on the back side of the light emitting area 10a of the ornament unit 10 and functions as an irradiator that emits light toward the front of the light emitting area 10a.
The lamp 31 is suitable as a light source for vehicle illumination, such as an LED lamp.
The light guide 32 is a long light guide plate, and as shown in FIG. 7, the vertical width gradually increases from the front end to the rear end in the longitudinal direction.

  The light guide 32 is fitted into a holder 33 that is a frame formed to match the outer shape of the light guide 32 and is held by the holder 33. The holder 33 is preferably white so that light emitted from the light guide plate can be favorably reflected. For example, the holder 33 is formed of a material in which a white pigment is added to PC resin.

A lamp 31 is attached to the holder 33 at a position adjacent to the front end portion of the light guide 32. Thus, if the lamp 31 is mounted at a position adjacent to the front end portion of the light guide 32, the light traveling direction and the light guide direction by the light guide 32 coincide with each other, so that a good light guide effect is obtained. I can do it. In particular, in the present embodiment, the width of the front end portion on the side where the lamp 31 is attached is narrower than that of the rear end portion among the both ends in the longitudinal direction of the light guide 32. That is, since the width of the light guide plate increases toward the downstream side in the light traveling direction, the light from the lamp 31 spreading in a fan shape can be guided more appropriately.
When the length of the light guide 32 is relatively long, the lamps 31 may be attached to the sides of the light guide 32 at both ends in the longitudinal direction.

  The light source unit 30 having the above configuration is assembled in a snap-fit manner on the back side of the ornament unit 10. Specifically, as shown in FIG. 7, the light source unit 30 includes an engagement hole forming portion 34 that protrudes upward or downward from the outer edge of the holder 33. The engagement hole forming part 34 has a gate-shaped outer shape and forms a rectangular engagement hole 34a. The engagement hole 34a formed by the engagement hole forming portion 34 corresponds to the engaged portion, and is a hole in which the claw portion 16 provided on the ornament unit 10 side can be engaged.

As shown in FIG. 4, the claw portion 16 provided on the ornament unit 10 side is a portion protruding outward from the outer edge of the rib 15, and is provided at a position corresponding to the engagement hole 34a. That is, the claw portion 16 corresponds to a fixing portion for fixing the light source unit 30 and engages with the engagement hole 34a in order to assemble the light source unit 30 to the ornament unit 10 as shown in FIG.
The shape of the claw portion 16 will be described in detail. As shown in FIG. 8, a substantially U-shaped groove is formed in a portion of the claw portion 16 that protrudes from the rib 15. Inside the groove, a hook-like part 16a having a hook-like tip is formed, and on the outer side of the groove part, an encircling part 16b surrounding the hook-like part 16a is formed.

  When the light source unit 30 is assembled to the ornament unit 10, when the light source unit 30 is pressed against the back surface of the ornament unit 10 in a state where the light source unit 30 is set at a predetermined position, the hook-shaped portion 16 a of the claw portion 16 becomes the light source unit. Thus, the hook-shaped portion 16a bends so that its tip is introduced into the engagement hole 34a. Thereafter, the hook-like portion 16a returns to the state before bending when it is completely inserted into the engagement hole 34a, whereby the hook-like portion 16a is engaged with the engagement hole 34a. .

As shown in FIG. 9, when the light source unit 30 is assembled to the ornament unit 10, the engagement hole forming portion 34 of the light source unit 30 comes into contact with the rib 15. Thereby, the light source unit 30 is positioned with respect to the ornament unit 10, and the lamp 31 and the light guide 32 are accommodated in the rib 15.
When the light source unit 30 is positioned with respect to the ornament unit 10, adjustment is made so that the distance between the light guide 32 and the ornament base material 11 in the light emitting region 10 a of the ornament unit 10 is a predetermined distance d. Is done. The predetermined distance d is a distance set such that the illuminance when the light emitting region 1a emits light becomes a desired illuminance and a good illumination effect is obtained with respect to the interval between the light guide 32 and the ornament unit 10. .

After the light source unit 30 is assembled to the ornament unit 10, the ornament unit 10 is fixed to the door base 4, and the boss 13 and the engagement protrusion 14 provided on the ornament unit 10 side are fastened to the door base 4.
On the other hand, on the light source unit 30 side, as shown in FIG. 4, a boss 35 and an engagement protrusion 36 that are fastened to the door base 4 are formed as a light source unit side fixing portion.
