2. Description of the Related Art As is well known, a vehicular lamp is usually provided with a housing having a light emitting opening on the front surface, and a plate-shaped or lens-shaped lamp cover covering the light emitting opening. It is composed of a housing and a light source arranged in a lamp chamber (lamp chamber) defined by a lamp cover. The inner wall of the housing is provided with a reflective layer integral with it or is otherwise provided with a separate reflector. In such a vehicle lamp, when the light source is turned on, the direct light from the light source and the reflected light after being reflected by the inner wall of the housing are emitted to the outside of the lamp via the lamp cover. The lighting function of the period is demonstrated.

In recent years, in such a vehicular lamp, not only an illumination function when turned on but also an improvement in appearance when turned off during the daytime are required. One of the ornaments often used to improve the appearance of a vehicular lamp is a lamp garnish or finisher. These ornaments are usually lamp covers for headlamps, rear combination lamps, etc. (also called outer covers).
Is attached so that the irradiation light path from the light source is removed. In many cases, these ornaments have the same color as the vehicle body color or a plating color, and it is possible to improve the appearance by a sense of unity with the vehicle body. In addition, these ornaments can be manufactured in various thicknesses by resin injection molding, vacuum molding, extrusion molding, coating of paints, etc., and further, resin coloring, painting, printing, plating By adopting a coating, etc., it is possible to give it an appearance design. Such a decorative article is often pressure-bonded to an adherend by a pressure-sensitive adhesive layer provided on the back surface side.

However, the above-mentioned ornament is intended to improve the appearance when the surroundings are bright in the daytime, and it is expected that the same appearance as the daytime can be expected in the dark situation at night. I can't. In addition, conventional ornaments have a strong meaning of hiding the exterior part in order to eliminate the inconvenience that the ribs around the lamp and the black adhesive part are visible through the cover. It's not about raising it.

For reference, the utility model No. 30
No. 35801 discloses that a translucent luminous emission transfer sticker is attached to the inner surface of a transparent cover of a headlight of a vehicle in order to check the own vehicle in a dark parking lot. Further, Japanese Patent Laying-Open No. 11-11368 relates to a headlight of a bicycle, but an illuminant made of a phosphorescent material is arranged on the internal reflector side to emit light while the vehicle is stopped to allow the surrounding vehicles and pedestrians to see. It is disclosed that the user recognizes the existence of a bicycle.
However, these lamps merely improve the visibility by utilizing the light emission after turning off the light, do not have the decorative effect in the light off state during the daytime, and improve the appearance at night. Has not been done. Further, in the case of the former device relating to the headlight of the vehicle, the transparency is slightly deteriorated at the portion where the seal is attached, and the appearance is rather deteriorated when the light is turned off.

BEST MODE FOR CARRYING OUT THE INVENTION The vehicular lamp according to the present invention can be used in various fields as a lighting means, a marking means, a signal means, etc. Therefore, the light source and the light from the light source can be reflected by the inner wall. The basic form is not limited as long as it satisfies the requirement of including the housing, the light emitting opening, and the lamp cover attached to the light emitting opening. Examples of such vehicular lamps include, but are not limited to, those listed below, including headlamps, fog lamps, clearance lamps, stop lamps, tail lamps, turn signal lamps, backup lamps, and the like. Also,
The vehicular lamp may take the form of a combination lamp in which a plurality of lamps are combined. For example, the vehicular lamp can be used as a rear combination lamp around the rear of the vehicle or as a front combination lamp around the front. In the practice of the present invention, a headlamp is particularly suitable as a lamp.

The vehicle in which the lamp of the present invention is used is not particularly limited and includes passenger cars (including RV cars, campers, etc.), buses, trucks and the like. It is particularly suitable for passenger cars, because the appearance and design can be improved.

FIG. 1 shows a general structure of a vehicular lamp according to the present invention. The lamp 20 has a housing 2
2 and 1 defined by the lamp cover 23 mounted so as to cover the light emitting opening (light emitting region) on the front surface thereof.
An individual lamp room (light room) 25 is provided. The lamp room 2
5 may consist of two or more chambers, if desired. The respective lamp chambers may be independent of each other or may be in communication with each other. In the lamp chamber, a light source 21 having an appropriate brightness is usually arranged by fitting it into a socket (not shown) or the like. Further, in the illustrated example, one light source 21 is attached, but if necessary, two or more light sources 21 may be arranged in one lamp chamber 25.

The inner wall 22a of the housing 22 is a light source 21.
It has a reflective film structure such as a concave mirror so that the light from is condensed. Such a reflective film structure can be formed as a plated thin film by, for example, vapor deposition of aluminum.
Further, according to another aspect, a concave mirror or a similar light reflecting means (generally, a reflector) may be provided in the lamp chamber 25 in addition to the inner wall. Further, the light source 21 may have a cap colored in a predetermined color, if necessary. This is because when a colored cap is used, a colorless cover can be used as the lamp cover instead of the colored cover. The light L ₁ from the light source 21 is reflected by the inner wall 22 a and then emitted from the lamp cover 23 as illustrated.

To reflect the recent tendency, the lamp cover 23 has a light non-transmissive region that is not substantially involved in the emission of light from the light source 21, that is, a non-transparent region in order to improve the appearance and design. A light emitting area is attached. Further, in the non-light emitting area, the accessory 10 with a light storing layer is provided according to the present invention. In the illustrated example, the accessory 10
Is attached to the outside of the lamp cover 23,
In the case of the present invention, it can also be attached to the inside as described below.

In the vehicular lamp of the present invention, the light emitting opening of the lamp chamber (the light emitting region and the non-light emitting region adjacent thereto)
Attach the lamp cover to. The lamp cover is not particularly limited as long as it has a shape and size at least covering the light emitting surface of the lamp chamber,
It is generally circular, rectangular or square, and may have a deformed shape such as an oval or an L-shape in some cases.

The lamp cover may be colorless and, if desired, that is to say colored according to the hue of the light emitted from it. Further, if the lamp chambers are a combination of two or more chambers, each lamp chamber may be colored with a different hue.

A colorless or colored lamp cover is
It can be advantageously formed by molding from any light transmissive resin. Suitable molding methods include conventional molding methods such as injection molding and vacuum molding. The raw material resin used for molding is not limited to those listed below, but examples thereof include a styrene resin, a hard vinyl chloride resin, an acrylic resin, and a polycarbonate resin. In particular, acrylic resin can be advantageously used. This is because it has excellent strength and transparency and can be advantageously subjected to coloring. If necessary, the lamp cover may be formed of glass or other transparent material.

Furthermore, when manufacturing a colored lamp cover, an appropriate amount of a coloring agent can be mixed in the resin raw material as described above. Suitable colorants include, but are not limited to, those listed below, pigments such as perylene pigments, azo pigments, iron oxides, or quinophthalone dyes, azo dyes, disazo dyes, anthraquinone dyes, benzopyran dyes, etc. Dyes (all from the color index) can be mentioned.

In the production of the lamp cover, the resin raw material may be mixed with additives commonly used in the field of plastic molding, in addition to the colorant. Examples of suitable additives include ultraviolet absorbers, light stabilizers, and heat stabilizers. For example, suitable UV absorbers include, but are not limited to, those listed below, including benzotriazoles, benzophenones, diphenyl acrylates, amine UV absorbers, and the like.

The lamp cover is usually flat and has a smooth surface. However, if a lens function is also required, the inner surface of the lamp cover (the surface on the light source side) is covered. An uneven pattern may be provided. Further, a lamp cover having a three-dimensional curved surface or the like may be used in order to improve the appearance and design.

Outer surface of lamp cover (surface facing outward)
May usually be covered with a thin, transparent plastic film, if desired, but for protection purposes, although it usually does not have any. This is because it is possible to prevent damage to the lamp cover when it is hit by small gravel or the like. Examples of suitable plastic films include films of polyester resin, polyethylene resin, polycarbonate resin, vinyl chloride resin, acrylic resin, polyurethane resin, polyolefin resin, vinylidene fluoride resin and the like.

In the lamp cover of the present invention, the non-luminous area, that is, the light non-transmissive area where the light emitted from the light source arranged in the lamp chamber does not pass or is not required to pass such light, The accessory of the present invention is provided.

Although various regions can be considered as the non-luminous region of the lamp cover, it is usually the peripheral region of the light emitting opening of the lamp chamber. That is, the non-light emitting area is an area around the head lamp, the turn signal lamp, the backup lamp and the like. These non-luminous regions can usually have any shape in accordance with the peripheral region of the light emitting opening.

In addition, the non-luminous area of the lamp cover is based on the inspection procedure of the safety standard Article 32 (headlights, etc.) of road transport vehicles (see 3-2 of 4-21), and the illumination section and the instruction section. Alternatively, it can be defined as pointing to a region other than the reflection part. That is, in the schematic diagram shown in FIG. 2, a portion C excluding the lens portion A having a luminous intensity of 98% of the central luminous intensity and the lens portion B on which direct light is incident on the drawing is a non-light emitting region in the present invention.

Since the decorative article of the present invention is arranged only in the non-light emitting area as described above that does not adversely affect the progress of light from the light source, it is excellent in daytime while satisfying the requirements such as vehicle operation rules. It is possible to simultaneously achieve a beautiful appearance due to the decorative effect and the afterglow effect at night. The appearance-imparting layer included in the accessory can ensure excellent decorativeness in the daytime, and the light energy stored in the phosphorescent layer during daytime lighting illuminates the inside of the lamp chamber 25 as afterglow L ₂ at night, which is beautiful. This is because the appearance can be obtained (see FIG. 1).

The jewelery of the present invention has a wide range of uses because it can provide a new and beautiful appearance that has never been experienced. Typical uses of the accessory include, but are not limited to, those listed below, stickers, emblems, lamp garnishes, finishers, and the like. These ornaments can exhibit their full value more than especially when they are used by being attached to a lamp for a vehicle. Of course, it is also possible to use it for a display application or the like, if necessary.

The accessory of the present invention can be provided in many forms according to the variety of uses thereof. The accessory is generally provided in the form of a sheet or film, preferably in the form of a multilayer structure sheet or film, but through the selection of the elements constituting the accessory, the form of a coating film by coating or painting, a resin sheet. It can be provided in the form of a panel by the combined use of the above, a form of a resin molded body utilizing resin molding, and the like.

In any of the embodiments, the accessory of the present invention is (1) an appearance-applying layer that defines the appearance of the accessory, and (2) a light source that is closer to the light source than the appearance-applying layer. And at least a phosphorescent layer capable of generating afterglow. It should be noted that the term "layer", when used in the present invention, is to be understood not only in a relatively thin layer or thin film as generally understood, but also in the detailed description below. In addition, it includes thick layers and thick films, films and sheets, and molded articles having a predetermined thickness.

Generally speaking, since the appearance-imparting layer, which is the first element constituting the accessory, defines the appearance of the accessory, it is made of various materials depending on the desired decorative effect. , Can be formed in various ways. Appropriate appearance-imparting layers are not limited to those listed below, but include printing layers such as ink, coating layers such as paints,
A colored resin layer, a metal plating layer, a metal vapor deposition layer, a metal foil layer or other colored layers, etc.
You may use combining a layer or more. Further, the appearance-imparting layer may be a colored member having a thickness and a shape.

The phosphorescent layer used in combination with the appearance-imparting layer needs to have the ability to store light from the light source and generate afterglow. Therefore, the phosphorescent layer may be composed of a layer of a material having a phosphorescent ability (a phosphorescent material) itself, or may be composed of a layer containing a phosphorescent material. Considering manufacturing efficiency, cost, and the like, it is advantageous to form the luminous layer from a material containing a luminous material.
The phosphorescent layer is usually provided over the entire area of the accessory according to the appearance-imparting layer, but it may be provided only in a part of the area of the accessory as long as the desired effect of light accumulation can be obtained. . The phosphorescent layer may be used as a single layer or as a combination of two or more layers. Further, the phosphorescent layer may be a member having a thickness and a shape.

The accessory of the present invention can optionally have an additional layer in addition to the appearance-imparting layer and the luminous layer. The accessory can have additional layers such as, for example, a bonding layer, a support layer, a base layer, an adhesive layer, a clear layer, and the like. For example, it is preferable that the accessory is usually attached to the lamp cover via an adhesive layer made of a pressure sensitive adhesive or a heat sensitive adhesive. If necessary, a double-sided adhesive tape or the like may be used instead of using the adhesive layer. further,
If the accessory is attached to the outer surface of the lamp cover, it is preferable to further provide a clear layer as the outermost layer.

The accessory of the present invention may be attached to the outer surface of the lamp cover or may be attached to the inner surface of the lamp cover. Hereinafter, the basic configuration of the accessory of the present invention will be described with reference to these two usage patterns. 3 and 4 to be referred to below show an accessory in the form of a multilayer structure film, but as already described, some of the components of the accessory are members having a thickness or shape. In the form of, or need not be one continuous layer. In addition, a method other than the method using the illustrated adhesive can be arbitrarily used to attach the accessory.

It may be used as a single layer or may be used by laminating two or more layers. In principle, the first and third intermediate layers 11 and 13 are colorless and transparent, and at least have an adverse effect on the designability derived from the appearance-imparting layer 15 and the transmission of afterglow from the luminous layer 16. must not. In addition, the adhesive layer 14
Must not impair the design of the appearance imparting layer 15. If necessary, the arbitrary layer located below the appearance-imparting layer 15 (on the light source side) may have a light-storing effect.

More specifically, the appearance-imparting layer is
As described above, the printing layer, the coating layer, the coloring resin layer, the metal plating layer, the metal vapor deposition layer, the metal foil layer or other coloring layers or coloring members are preferable.

For example, the colored layer can be formed using a variety of conventional thin film forming techniques. That is,
The colored layer may be formed by printing or painting (including electrostatic coating) ink or paint having a predetermined color tone, or coating, extruding, or pasting a film or sheet having a predetermined color tone. You may form by doing. The ink or paint may contain a glittering agent such as pearl powder or metal powder, and other additives.
The colored layer forming material used here preferably has not only colorability but also excellent weather resistance which is a requirement for the lamp cover.

Further, according to one embodiment thereof, the coloring layer is made of a plastic film such as a polyester film, a polyethylene film, a polycarbonate film, a vinyl chloride film, an acrylic film, a polyurethane film, a polyolefin film or a vinylidene fluoride film. Can be formed in the form of. The plastic material used here may be resin alone,
Alternatively, it may be a mixture of resins or a copolymer. The colored film can be produced with a desired film thickness by mixing an appropriate coloring agent such as a pigment or a brightening agent into the raw material resin and then using a conventional molding method such as a calender molding method.

According to another embodiment, the coloring layer may be formed so as to have a design appearance by printing, painting, metal thin film or the like on a film made of a plastic material produced without mixing a coloring agent. . An example of such a form is a finisher. The finisher is formed by forming a main body from a resin such as polyphenylene ether (PPE) by injection molding or the like, and then painting or plating the same color as the vehicle body on the surface to give a metallic appearance. In other words, it is a combination of the appearance-imparting layer and the second intermediate layer.

The colored layer can also be formed in the form of a metallic coating by metal plating, metal vapor deposition or the like. The metallic coating may be formed, for example, by vapor deposition or sputtering of a metal material such as aluminum, chromium, tin or the like. Otherwise, a coating such as a resin in which metal powder such as aluminum powder is dispersed, a glitter ink or a glitter It may be formed by printing or coating (including electrostatic coating) of a coating material in which the agent is dispersed, such as pearl mica coating material. Furthermore, a metallic coating may be formed by coating, extruding a resin, or sticking a film or sheet having a desired appearance. The film-forming material used here preferably has not only the desired appearance but also excellent weather resistance, which is a requirement for the lamp cover.

The appearance-imparting layer may additionally have a pattern, a picture, characters, etc., if necessary. This is because the appearance design of the accessory is further improved.

The thickness of the appearance-providing layer can be widely varied depending on the desired appearance and design, but it is usually in the range of about 5 to 500 μm, more preferably about 20 to 100 μm. It is a range. However, in the case where the appearance-imparting layer has a thickness or a shape, it goes without saying that a thickness outside the above range can be applied.

The phosphorescent layer is preferably formed of a layer or member containing a phosphorescent material. The phosphorescent material is preferably a phosphorescent pigment, generally a sulfide pigment, an aluminate pigment and the like. A combination of an aluminate pigment with an activator such as europium is preferable in order to enhance the emission brightness and the afterglow performance. As an example of such a phosphorescent pigment, although not limited to those listed below, europium-cisprosium-activated strontium aluminate phosphor, europium-neodymium-yttrium-activated calcium aluminate phosphor, europium Examples thereof include neodymium-activated barium aluminate phosphor. These phosphorescent pigments are usually
A stable afterglow effect can be exhibited over a long period of 10 to 15 hours. In addition, these phosphorescent pigments may be used alone or in combination of two or more kinds.

The light-storing material can usually be used advantageously by mixing it in a suitable amount in a resin material. A resin material suitable for forming the luminous layer is, for example, a resin material used for forming the appearance providing layer. In such a resin material, the phosphorescent material is blended in an amount up to about half the weight of the entire phosphorescent layer, but the present invention is not limited to this. Usually, a blending amount of about 10 to 50% by weight is preferable.

The thickness of the light-storing layer can be widely varied depending on the desired appearance and design, but it is usually in the range of about 5 to 500 μm, and more preferably in the range of about 20 to 100 μm. Is. However, if there is a thickness or shape in the phosphorescent layer, of course,
Thicknesses outside the above range are applicable.

Since the accessory of the present invention has a waist, it is preferable to dispose an intermediate layer adjacent to the appearance-imparting layer and the light-accumulating layer. The intermediate layer can function as, for example, a bonding layer, a support layer, a base layer, a hiding layer, or the like. Suitable intermediate layers are, for example, a joining layer made of polyurethane resin or the like, or a base layer made of polyester resin, polyphenylene ether resin or the like. These intermediate layers may be used as a single layer or as a laminate of two or more layers.

Since the accessory is attached to the lamp cover, it generally has an adhesive layer. The adhesive layer used here can be formed using an adhesive that is commonly used in the field of adhesive tapes, pressure-sensitive adhesive tapes, and the like, for example, pressure-sensitive type, heat-sensitive type, and photocurable type adhesives. Examples of suitable adhesives include pressure-sensitive adhesives such as acrylic adhesives and rubber adhesives, and heat-sensitive adhesives such as polyurethane adhesives and polyester adhesives. In particular, acrylic adhesives can be advantageously used in consideration. In the case of pressure-sensitive adhesive, it is attached by pressing the accessory on the lamp cover, and in the case of heat-sensitive adhesive, the accessory is heated or pasted on the lamp cover which has been heated in advance, or by pressure bonding. Then, apply the cover by heating it together with the cover. Further, instead of providing the adhesive layer on the accessory, it may be provided on the lamp cover side in advance. Further, a double-sided adhesive tape or the like may be used instead of the adhesive layer.

The adhesive layer is usually transparent. But,
If the adornment is to be applied to the outer surface of the lamp cover, it need not be transparent anymore if the adhesive layer itself has a light-storing effect. Further, even when the adhesive layer is partially used, the adhesive layer does not necessarily need to be transparent as long as it does not adversely affect the afterglow of the luminous layer. The point is that a light-storing layer is provided somewhere on the light source side of the appearance-imparting layer, and when viewed from the adhesive layer, the light-transmitting layer from the lowermost layer to the light-storing layer should be partially translucent. Good.

Although the thickness of the adhesive layer can be varied over a wide range, it is usually in the range of about 10 to 500 μm, more preferably in the range of about 20 to 100 μm. If the thickness of the adhesive layer is less than 10 μm, it is not possible to obtain a satisfactory adhesive force, and conversely 500 μm.
If it exceeds, the total thickness of the accessory becomes very large, which is not preferable. In fact, when the accessory is attached to the outer surface of the lamp cover, the lamp cover protrudes from the cover, which causes a feeling of strangeness. The thickness of the double-sided pressure-sensitive adhesive tape is usually about 1 mm.

When the ornamental tool of the present invention is used by attaching it to the outer surface of the cover film, it is preferable that it further has a clear layer as the outermost layer. From the viewpoint of causing the clear layer to act as a protective film, it is desirable that the clear layer has weather resistance and heat resistance in addition to transparency, which is an essential property. It is also desirable that the clear layer has good adhesion to the underlying layer. Suitable resins for forming the clear layer are not limited to those listed below, but include polyester resin, polyethylene resin, polycarbonate resin, vinyl chloride resin, acrylic resin, polyurethane resin, polyolefin resin, fluorine resin (PVdF). , ETFE, etc.) and the like. If necessary, these resins may be used as a mixture or a copolymer. Furthermore, the clear layer can also impart gloss to the surface of the lamp cover and improve the appearance.

In order to enhance the weather resistance of the clear layer,
It is preferable to mix an ultraviolet absorber. Suitable UV absorbers include, but are not limited to, those listed below, including benzotriazole UV absorbers, benzophenone UV absorbers, cyanoacrylate UV absorbers, and the like.

Further, the thickness of the clear layer can be widely varied depending on the desired effect, etc., but is usually in the range of about 10 to 500 μm, and more preferably in the range of about 20 to 100 μm. is there. If the thickness of the clear layer is less than 10 μm, the effect as a protective film cannot be obtained, and if it exceeds 500 μm, the total thickness of the accessory is too large, which is not preferable.

As described above, the vehicular lamp of the present invention is characterized in that the portion other than the irradiation light path of the lamp cover is provided with the luminous accumulator with the appearance-imparting layer of the present invention. With the lamp having such a structure, it is possible to obtain an excellent appearance design property due to the appearance imparting layer during running or stopping in the daytime. Further, when the light source is turned on, the irradiation light from the light source is emitted to the outside without being influenced by the accessory, and the original function of the lamp is not adversely affected. Further, when the light source is turned on, light that is complicatedly refracted or scattered in the lamp chamber can hit the accessory. Such light striking the accessory is again emitted into the lamp chamber as afterglow due to the light storing action of the light storing layer. As a result, when the lights are turned off at night, the afterglow that is continuously radiated illuminates the lamp room brightly, resulting in a beautiful and eye-catching appearance. Since the afterglow in this case is, so to speak, surface emission, different from the emission from the light source, a uniform appearance can be obtained. In addition, the lighting effect can be variously changed by previously coloring the type of the light-accumulating pigment and the layer through which light passes. In order to enhance this effect due to afterglow, it is preferable that the inner wall of the housing is colored in a plating tone by vapor deposition of aluminum or the like. Afterglow will be reflected by a reflective film such as the aluminum vapor deposition surface, and a glittering colored appearance will be obtained.
