Description

The present invention relates to a vehicle lamp in which first and second lamp units are housed in a lamp chamber.

A conventional vehicle lamp configuration is one in which a first and second lamp unit are housed within a lamp chamber formed by a lamp body and a translucent cover.

Patent Document 1 describes such a vehicle lamp in which a first light-transmitting area in which the light emitted from a first lamp unit passes through a light-transmitting cover and a second light-transmitting area in which the light emitted from a second lamp unit passes through a light-transmitting cover are arranged at a required distance.

The light-transmitting cover of the vehicle lamp described in "Patent Document 1" is composed of multicolored molded lenses, and has an intermediate region located between the first light-transmitting region and the second light-transmitting region. is made up of smoke-colored dummy lenses.
Japanese Patent Application Publication No. 2000-251505

In the vehicle lamp described in Patent Document 1, if the color of the dummy lens constituting the intermediate area of the light-transmitting cover is changed to black, etc., the light-transmitting cover can be removed between the first and second lamp units. It becomes possible to prevent light leakage from occurring due to the light guiding effect.

By adopting such a configuration, when either one of the first and second lighting units is turned on, the other lighting unit is prevented from appearing to shine dimly. This makes it possible to improve the appearance of the vehicle lamp.

However, if the translucent cover is made of a multi-color molded lens in this way, the manufacturing costs of the vehicle lamp will be high.

On the other hand, if the light-transmitting cover is configured with a single lens and a light-shielding film is formed on the front surface of the intermediate area, even when either the first or second lighting unit is lit, It is possible to prevent the intermediate region of the light-transmitting cover from appearing shiny.

However, even when such a configuration is adopted, when either one of the first and second lighting units is turned on, the other lighting unit becomes dimly bright due to the light guiding action of the transparent cover. The phenomenon of appearing shiny cannot be eliminated.

The present invention has been made in view of these circumstances, and aims to improve the appearance of a vehicle lamp in which the first and second lamp units are housed in the lamp chamber while suppressing its manufacturing cost. The object of the present invention is to provide a vehicular lamp that can perform the following functions.

The present invention aims to achieve the above object by devising the structure of the light-transmitting cover.

That is, the vehicle lamp according to the present invention is
A vehicular lamp in which first and second lamp units are housed in a lamp chamber formed by a lamp body and a transparent cover,
The first and second lighting units have a first light-transmitting region in which light emitted from the first lighting unit passes through the light-transmitting cover, and a first light-transmitting region in which light emitted from the second lighting unit passes through the light-transmitting cover. and the second light-transmitting region are arranged in parallel with a required interval,
A first light-shielding film is formed on the front surface of an intermediate region located between the first light-transmitting region and the second light-transmitting region in the light-transmitting cover,
An uneven portion is formed on the rear surface of the intermediate region of the transparent cover,
A colored film covering the first light-shielding film is formed on the front surface of the light-transmitting cover .

In the above-mentioned "first and second lighting units", if the first light-transmitting area and the second light-transmitting area are arranged in parallel with a required interval, the specific positional relationship between the two is particularly limited. It is not limited.

Each of the above "first and second lamp units" may be configured to allow the light emitted from the light source to enter the translucent cover as is, or may be configured to allow the light emitted from the light source to enter the translucent cover in a state in which the light is controlled by a reflector, lens, etc.

The specific configuration of the above-mentioned "first light-shielding film" is not particularly limited as long as it is a film that has a light-shielding function, and for example, a coating film or a vapor deposition film can be used.

The specific configuration of the "uneven portion" is not particularly limited, and may be, for example, a plurality of grooves formed in a striped or lattice pattern, a single groove, or a groove formed by applying a graining or frosting process.

In the vehicle lamp according to the present invention, first and second lamp units are housed in a lamp chamber formed by a lamp body and a transparent cover, and the first and second lamp units are connected to the first lamp unit. The first light-transmitting area where the emitted light from the unit passes through the light-transmitting cover and the second light-transmitting area where the light emitted from the second lighting unit passes through the light-transmitting cover are arranged in parallel with a required interval. However, a first light-shielding film is formed on the front surface of an intermediate region located between the first light-transmitting region and the second light-transmitting region of the light-transmitting cover, and Since the uneven portion is formed on the rear surface, the following effects can be obtained.

That is, since the first light-shielding film is formed on the front surface of the intermediate area of the transparent cover, when either one or both of the first and second lighting units is lit, the intermediate area of the transparent cover is illuminated. You can make it invisible.

In addition, since an uneven portion is formed on the rear surface of the intermediate region of the light-transmitting cover, the light that enters the intermediate region when either the first or second lighting unit is turned on is prevented from being specularly reflected on the rear surface. This makes it possible to prevent light from being guided to the light-transmitting area of the other lamp unit.

Therefore, the vehicle lamp according to the present invention can effectively prevent the occurrence of a phenomenon in which, when either the first or second lamp unit is turned on, the other lamp unit appears to be lit dimly.

As described above, according to the present invention, it is possible to improve the appearance of a vehicle lamp in which the first and second lamp units are housed in the lamp chamber while reducing manufacturing costs.

In the above structure, if a second light-shielding film is further formed on the rear surface of the intermediate region of the light-transmitting cover, the following effects can be obtained.

In other words, the translucent cover has a structure in which an uneven portion is formed on the rear surface of the intermediate region, but depending on the surface shape, some of the light incident on the intermediate region of the translucent cover may exit from the rear surface. After that, there is a possibility that a situation may occur in which the light re-enters the intermediate region and is guided to the light-transmitting region of the other lamp unit. On the other hand, by forming the second light-shielding film on the rear surface of the intermediate region of the light-transmitting cover, it is possible to prevent such a situation from occurring. As a result, it is possible to more effectively suppress the phenomenon in which the other lamp unit appears to shine dimly and brightly.

In the above configuration, if the uneven portion is further configured with at least one groove portion formed so as to extend in a direction intersecting the direction connecting the first and second light-transmitting regions, the effect of preventing light from being guided in the intermediate region can be enhanced.

At this time, if the groove has a rectangular cross-sectional configuration, the effect of preventing light from being guided in the intermediate region can be maximized.

In the above structure, if a colored film covering the first light shielding film is further formed on the front surface of the light-transmitting cover, the following effects can be obtained.

That is, in order to prevent the middle area of the light-transmitting cover from appearing shiny when either or both of the first and second lighting units are turned on, the color of the first light-shielding film should be changed to black, for example. It is preferable to set it to a dark color such as . However, in this case, there is a risk that the appearance of the vehicle lamp when it is not lit may be impaired. Therefore, if the first light-shielding film is covered with a colored film formed on the front surface of the light-transmitting cover, the light-transmitting cover can be seen in the color of the colored film when the light is not lit. The appearance can be improved.

The specific formation range of the above-mentioned "colored film" is not particularly limited as long as it is formed to cover the first light-shielding film. For example, the "colored film" is formed over the entire front area of the light-transmitting cover. It is also possible to have a configuration. At that time, by forming the above-mentioned "colored film" to cover the first and second light-transmitting regions and reducing the thickness of the film, a certain degree of light-transmission is achieved in the first and second light-transmitting regions. It is also possible to ensure that the

In the above configuration, the first lamp unit further includes a first reflector that reflects the light emitted from the first light source toward the front of the lamp, and the second lamp unit reflects the light emitted from the second light source. The structure includes a second reflector that reflects light toward the front of the lamp, and a gap between the front end surface of the first reflector and the rear surface of the transparent cover is closed between the first reflector and the transparent cover. A first packing formed as shown in FIG. If the configuration includes the second packing, the following effects can be obtained.

In other words, light leaking from between the first reflector and the light-transmitting cover may enter the second light-transmitting area, or light leaking from between the second reflector and the light-transmitting cover may enter the first light-transmitting area. It is possible to prevent such incident from occurring. As a result, when one of the first and second lighting units is turned on, it is possible to more effectively suppress the phenomenon in which the other lighting unit appears to shine dimly.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan cross-sectional view showing a vehicle lamp 10 according to an embodiment of the present invention. Further, FIG. 2 is a view taken in the direction of arrow II in FIG.

In Figures 1 and 2, the direction indicated by X is "in front of the lamp," the direction indicated by Y is the "left direction" (the "right direction" when viewed from the front of the lamp) perpendicular to the "in front of the lamp," and the direction indicated by Z is the "upward direction." This is the same for the other figures.

As shown in Figures 1 and 2, the vehicle lamp 10 according to this embodiment is an accessory lamp that is installed at the front end of the vehicle to indicate intentions to drivers of oncoming vehicles, and is configured such that first and second lamp units 20A and 20B are housed within a lamp chamber formed by a lamp body 12 and a translucent cover 14.

This vehicular lamp 10 has a symmetrical shape, and its transparent cover 14 has a horizontal cross-sectional shape of a convex curve that slightly bulges toward the front side of the lamp.

The first and second lamp units 20A and 20B both have the same configuration and are arranged in parallel with a required interval in the left-right direction.

The first lamp unit 20A is configured with a first light source 22A and a first reflector 24A that reflects the light emitted from the first light source 22A toward the front of the lamp.

The first light source 22A is a light-emitting diode that emits white light and is supported on the lamp body 12 via a support substrate 26A with its light-emitting surface facing toward the front of the lamp.

The first reflector 24A has a reflecting surface 24Aa configured as a paraboloid of revolution whose central axis is an axis Ax extending in the longitudinal direction of the lamp so as to pass through the light emission center of the first light source 22A. 24Aa, the light emitted from the first light source 22A is reflected toward the front of the lamp as substantially parallel light. The first reflector 24A is formed into a cylindrical shape so that its rear end surrounds the first light source 22A, and is supported by the lamp body 12 at its rear end 24Ab.

A first packing 28A is arranged between the first reflector 24A and the transparent cover 14, and is formed to close the gap between the front end surface 24Ac of the first reflector 24A and the rear surface 14b of the transparent cover 14. ing.

The first packing 28A is made of, for example, sponge rubber, and is formed to extend in an annular shape along the front end surface 24Ac of the first reflector 24A. At this time, the first packing 28A is formed so that its thickness gradually changes depending on the distance between the front end surface 24Ac of the first reflector 24A and the rear surface 14b of the light-transmitting cover 14.

On the other hand, the second lamp unit 20B includes a second light source 22B similar to the first light source 22A, and a second reflector 24B similar to the first reflector 24A.

That is, the second light source 22B is supported by the lamp body 12 via the support substrate 26B, and the second reflector 24B is supported by the lamp body 12 at the rear end 24Bb. Further, a second packing 28B similar to the first packing 28A is arranged between the front end surface 24Bc of the second reflector 24B and the rear surface 14b of the light-transmitting cover 14. This second packing 28B has a laterally symmetrical shape with respect to the first packing 28A.

In this vehicle lamp 10, a circular area located on the inner circumferential side of the first packing 28A constitutes a first light-transmitting area Za through which light emitted from the first lamp unit 20A passes through the light-transmitting cover 14. Further, a circular region located on the inner circumferential side of the second packing 28B constitutes a second light-transmitting region Zb through which light emitted from the second lamp unit 20B passes through the light-transmitting cover 14. There is. These first and second light-transmitting regions Za and Zb are arranged in parallel with a required interval in the left-right direction.

FIG. 3 is a detailed view of section III in FIG. 1.

As shown in FIG. 3, the first light-shielding film 16 is formed on the front surface 14a of the intermediate region 14c located between the first light-transmitting region Za and the second light-transmitting region Zb in the light-transmitting cover 14. ing.

In addition, an uneven portion 14d is formed on the rear surface 14b of the intermediate region 14c of the light-transmitting cover 14. This uneven portion 14d is composed of multiple grooves 14d1 extending in the vertical direction. All of these multiple grooves 14d1 are formed with the same cross-sectional shape and are arranged at equal pitches. Specifically, each groove 14d1 has a horizontal cross-sectional shape of a horizontally elongated rectangle, and the left-right width and the distance between each groove 14d1 are set to approximately the same value.

Furthermore, a second light-shielding film 18 is formed on the rear surface 14b of the intermediate region 14c of the light-transmitting cover 14. The second light-shielding film 18 is a black painted film, and is formed to have a vertically long rectangular outer shape so as to cover the uneven portion 14d.

In this manner, a first light-shielding film 16 is formed on the front surface 14a of the intermediate region 14c of the light-transmitting cover 14, an uneven portion 14d is formed on the rear surface 14b of the intermediate region 14c, and a second light-shielding film 18 is formed on the rear surface 14b of the intermediate region 14c, thereby preventing light leakage due to the light-guiding effect in the intermediate region 14c.

For example, as shown in FIG. 3, light that enters the transparent cover 14 from the second lighting unit 20B side is guided to the intermediate region 14c while repeating total reflection on the front surface 14a and rear surface 14b, and is guided to the intermediate region 14c. When heading to the side, this light reaches the uneven portion 14d formed on the rear surface 14b in the intermediate region 14c, but since the uneven portion 14d is composed of a plurality of grooves 14d1 extending in the vertical direction, At the portion 14d, light is prevented from being guided to the first lamp unit 20A side.

However, if the second light-shielding film 18 were not formed on the rear surface 14b of the intermediate region 14c, a portion of the light that reaches the uneven portion 14d would first be emitted from the groove portion 14d1 that constitutes the uneven portion 14d into the rear space of the intermediate region 14c, as shown by the two-dot chain line in the figure, and then re-enter the intermediate region 14c from the adjacent groove portion 14d1 and be guided toward the first lamp unit 20A.

However, in this embodiment, since the second light-shielding film 18 is formed on the rear surface 14b of the intermediate region 14c, the light that reaches the uneven portion 14d is absorbed by the second light-shielding film 18 instead of being emitted from the uneven portion 14d into the rear space of the intermediate region 14c, or, as shown by the solid line in the figure, the light that is not absorbed by the second light-shielding film 18 and is reflected by the second light-shielding film 18 is ultimately trapped in the uneven portion 14d between the multiple grooves 14d1, thereby preventing the light from being guided toward the first lamp unit 20A.

Therefore, when the first lighting unit 20A is lit, the first light-transmitting area Za appears to shine brightly, but at this time, the second light-transmitting area Zb does not appear to shine dimly, and the second light unit 20A does not appear to shine brightly. When 20B is turned on, the second light-transmitting area Zb appears to shine brightly, but at this time, the first light-transmitting area Za does not appear to shine dimly.

FIG. 4 is a diagram similar to FIG. 2, showing the vehicle lamp 10 according to the present embodiment in various lighting modes.

As shown in FIG. 4(a), the vehicle lamp 10 in which the first and second lamp units 20A and 20B are in the non-lighting state has a first light shield formed on the front surface 14a of the intermediate region 14c of the transparent cover 14. The membrane 16 is black and appears to have an elongated rectangular shape, and the first and second lamp units 20A and 20B are visible through the light-transmitting cover 14 on both the left and right sides thereof.

On the other hand, as shown in FIG. 4B, the vehicle lamp 10 in which the first and second lamp units 20A and 20B are in the lighting state has first and second light-transmitting areas on both left and right sides of the first light-shielding film 16. Za and Zb appear to shine brightly. At that time, the first and second light transmitting areas Za, Zb are such that the first and second light sources 22A, 22B appear to shine brightly with high luminance, and the reflective surfaces of the first and second reflectors 24A, 24B around them. 24Aa and 24Ba appear circular and brightly shining.

As shown in FIG. 4(c), when only the first lamp unit 20A is turned on, only the first light-transmitting area Za (i.e., the first light source 22A and the reflective surface 24Aa of the first reflector 24A) of the vehicle lamp 10 appears to be brightly lit. At that time, the middle area 14c of the light-transmitting cover 14 prevents light from leaking from the first lamp unit 20A to the second lamp unit 20B, so the second light-transmitting area Zb does not appear to be dimly lit.

Similarly, as shown in FIG. 4(d), in the vehicle lamp 10 in which only the second lamp unit 20B is in the lighting state, the second light transmitting area Zb (that is, the second light source 22B and the reflective surface of the second reflector 24B) Only 24Ba) appears to shine brightly. At this time, since light leakage from the second lighting unit 20B to the first lighting unit 20A side is prevented in the intermediate region 14c of the light-transmitting cover 14, the first light-transmitting area Za does not appear to shine dimly. do not have.

Next, the operation of this embodiment will be explained.

The vehicle lamp 10 according to the present embodiment has first and second lamp units 20A and 20B housed in a lamp chamber formed by a lamp body 12 and a transparent cover 14, and a first and a second lamp unit 20A and 20B. The lighting units 20A and 20B have a first light-transmitting area Za where the light emitted from the first lighting unit 20A passes through the light-transmitting cover 14, and a second light-transmitting area Za where the light emitted from the second lighting unit 20B passes through the light-transmitting cover 14. The light-transmitting areas Zb are arranged in parallel with a required interval, but if the light-transmitting area Zb is located between the first light-transmitting area Za and the second light-transmitting area Zb in the light-transmitting cover 14, Since the first light shielding film 16 is formed on the front surface 14a of the intermediate region 14c, and the uneven portion 14d is formed on the rear surface 14b, the following effects can be obtained.

That is, since the first light-shielding film 16 is formed on the front surface 14a of the intermediate region 14c in the light-transmitting cover 14, when either or both of the first and second lighting units 20A and 20B are turned on, the light-transmitting The intermediate region 14c of the cover 14 can be prevented from appearing shiny.

In addition, an uneven portion 14d is formed on the rear surface 14b of the intermediate region 14c of the translucent cover 14, so that light that enters the intermediate region 14c when either the first or second lamp unit 20A, 20B is turned on is not specularly reflected by the rear surface 14b, making it less likely to be guided to the translucent region of the other lamp unit.

Therefore, in the vehicle lamp 10 according to this embodiment, when either the first or second lamp unit 20A, 20B is turned on, the phenomenon in which the other lamp unit appears to be dimly lit can be effectively prevented.

As described above, according to the present embodiment, it is possible to improve the appearance of the vehicle lamp 10 in which the first and second lamp units 20A and 20B are housed in the lamp chamber while reducing manufacturing costs.

At this time, in the embodiment, since the color of the first light shielding film 16 is set to a dark color (specifically, black), either or both of the first and second lighting units 20A and 20B are turned on. In this case, it becomes possible to prevent the intermediate region 14c of the light-transmitting cover 14 from being seen as shiny.

Moreover, in this embodiment, since the second light shielding film 18 is formed on the rear surface 14b of the intermediate region 14c in the light-transmitting cover 14, the following effects can be obtained.

That is, although the translucent cover 14 has a structure in which an uneven portion 14d is formed on the rear surface 14b of the intermediate region 14c, depending on the surface shape, part of the light incident on the intermediate region 14c of the translucent cover 14 may After the light emitted from the rear surface 14b, a situation may occur in which the light enters the intermediate region 14c again and is guided to the light-transmitting region of the other lamp unit. In contrast, by forming the second light-shielding film 18 on the rear surface 14b of the intermediate region 14c of the light-transmitting cover 14 as in the present embodiment, such a situation can be prevented from occurring. It can be prevented. As a result, it is possible to more effectively suppress the phenomenon in which the other lamp unit appears to shine dimly and brightly.

At this time, in this embodiment, the uneven portion 14d is composed of a plurality of groove portions 14d1 that are formed to extend in the vertical direction (the direction that intersects the direction that connects the first and second light-transmitting regions Za and Zb). Therefore, the effect of blocking light guide in the intermediate region 14c can be enhanced.

Furthermore, since each groove portion 14d1 has a rectangular cross-sectional shape, the effect of preventing light guide in the intermediate region 14c can be maximized.

In the vehicle lamp 10 according to the present embodiment, a first lamp unit 20A includes a first reflector 24A that reflects light emitted from a first light source 22A toward the front of the lamp, and a second lamp unit 20B includes a first reflector 24A that reflects light emitted from a first light source 22A toward the front of the lamp. The configuration includes a second reflector 24B that reflects the light emitted from the two light sources 22B toward the front of the lamp. A first packing 28A formed to close the gap between the surface 24Ac and the rear surface 14b of the transparent cover 14 is arranged, and a first packing 28A is arranged between the second reflector 24B and the transparent cover 14. Since the second packing 28B is arranged to close the gap between the front end surface 24Bc of the second reflector 24B and the rear surface 14b of the light-transmitting cover 14, the following effects can be obtained.

In other words, it is possible to prevent light leaking between the first reflector 24A and the translucent cover 14 from entering the second translucent area Zb, and to prevent light leaking between the second reflector 24B and the translucent cover 14 from entering the first translucent area Za. This makes it possible to more effectively prevent the occurrence of a phenomenon in which, when either the first or second lamp unit 20A, 20B is turned on, the other lamp unit appears to be shining dimly.

In the embodiment described above, the uneven portion 14d is composed of a plurality of groove portions 14d1 extending in the vertical direction, each of which has the same horizontal cross-sectional shape of a horizontally long rectangle, and is arranged at an equal pitch. Although the explanation has been made assuming that the groove portion 14d1 is formed in a cross-sectional shape other than this, it is also possible to form the groove portion 14d1 in a different cross-sectional shape, to arrange the groove portions so that the pitch thereof changes, or even to consist of a single groove portion 14d1. . For example, it is also possible to adopt a configuration in which the uneven portions 14d are arranged such that the pitch changes according to an increase or decrease in the width of the intermediate region 14c in the left-right direction (Y direction).

In the above embodiment, the first and second lamp units 20A and 20B reflect the emitted light from the first and second light sources 22A and 22B toward the front of the lamps by the first and second reflectors 24A and 24B. In the above description, the light emitted from the first and second light sources 22A and 22B may be emitted toward the front of the lamp through a lens or as direct light. It is possible.

In the embodiment described above, the first and second light sources 22A and 22B are both composed of light emitting diodes that emit white light, but they also emit light in a color other than white (for example, blue or green). It is also possible to use a light emitting diode or the like, and in that case, it is also possible to make the first and second light sources 22A, 22B emit different colors.

In the above embodiment, the vehicle lamp 10 has been described as an accessory lamp, but it is also possible to configure it as another lamp (for example, a tail lamp, a stop lamp, a welcome lamp, etc.).

Next, we will explain a variation of the above embodiment.

First, we will explain the first variation of the above embodiment.

FIG. 5 is a diagram similar to FIG. 3, showing the main parts of the vehicle lamp 110 according to this modification.

As shown in FIG. 5, the basic configuration of this modification is the same as that of the above embodiment, but the structure of the light-transmitting cover 114 is partially different from that of the light-transmitting cover 14 of the above embodiment.

That is, in the light-transmitting cover 114 of this modified example, the intermediate region 114c located between the first light-transmitting region Za and the second light-transmitting region Zb has an uneven portion 114d formed on its rear surface 114b, but this uneven portion 114d is formed by applying an embossing process to the rear surface 114b of the intermediate region 114c, which differs from the above embodiment.

Further, in the light-transmitting cover 114 of this modification, the second light-shielding film 18 as in the above embodiment is not formed on the rear surface 114b of the intermediate region 114c.

Note that also in the light-transmitting cover 114 of this modification, the first light-shielding film 16 is formed on the front surface 114a of the intermediate region 114c.

In this modification, for example, light that enters the transparent cover 114 from the second lighting unit 20B side is guided to the intermediate region 114c while repeating total reflection on the front surface 114a and the rear surface 114b, and is guided to the first lighting unit 20A side. When the light reaches the uneven portion 114d formed on the rear surface 114b, it is reflected as scattered light at the uneven portion 14d.

In this modification, the light guided to the intermediate region 114c is diffusely reflected at the rear surface 114b without being specularly reflected, so that the light guided to the first lighting unit 20A side is effectively suppressed. It has become.

Note that the scattered light reflected by the uneven portion 14d is prevented from emitting into the space in front of the lamp by the first light shielding film 16 formed on the front surface 114a of the intermediate region 114c.

On the other hand, even if some of the light that has reached the uneven portion 14d is emitted into the space behind the lamp, there is no possibility that this emitted light will re-enter the intermediate region 114c from the uneven portion 14d. There isn't. Furthermore, since the first and second packings 28A and 28B are arranged between the first and second reflectors 24A and 24B and the transparent cover 14, the light emitted to the space on the rear side of the lamp is transmitted through the first transparent The light does not enter the light area Za or the second light-transmitting area Zb.

In addition, also in this modification, it is also possible to set it as the structure in which the 2nd light-shielding film 18 like the said embodiment was formed on the rear surface 114b of the intermediate area 114c in the light-transmitting cover 114.

Next, a second modification of the above embodiment will be described.

FIG. 6 is a diagram similar to FIG. 1 showing essential parts of a vehicle lamp 210 according to this modification.

As shown in FIG. 6, the basic configuration of this modification is the same as that of the above embodiment, but a colored film 230 that covers the first light shielding film 16 is additionally formed on the front surface 14a of the light-transmitting cover 14. This embodiment differs from the above embodiment in that

Specifically, the colored coating 230 is made of a white paint film and is formed over the entire area of the front surface 14a of the translucent cover 14. At this time, the thickness of the colored coating 230 is set to a value that ensures a certain degree of translucency in the first and second translucent areas Za, Zb.

In the vehicle lamp 210 according to this modified example, such a colored coating 230 is additionally formed on the front surface 14a of the translucent cover 14, so that when the direct light from the first and second light sources 22A, 22B and the reflected light from the reflective surfaces 24Aa, 24Ba of the first and second reflectors 24A, 24B pass through the translucent cover 14, they are emitted forward from the lamp as white scattered light by the colored coating 230 formed on the front surface 14a.

FIG. 7 is a diagram similar to FIG. 4 showing the vehicle lamp 210 according to the present modification in various lighting modes.

As shown in FIG. 7A, in the vehicle lamp 210 in which the first and second lamp units 20A and 20B are not lit, a colored coating 230 is formed over the entire area of the front surface 14a of the transparent cover 14. Therefore, the entire area appears white. At this time, the first light-shielding film 16 and the first and second lamp units 20A and 20B formed on the front surface 14a of the intermediate region 14c of the light-transmitting cover 14 are hidden by the colored film 230 and cannot be seen.

On the other hand, as shown in FIG. 7B, the vehicle lamp 210 in which the first and second lamp units 20A and 20B are in the lighting state has first and second light-transmitting areas on both left and right sides of the first light-shielding film 16. Za and Zb appear circular and shiny. At this time, the first and second light-transmitting regions Za and Zb appear to shine with substantially uniform brightness, although they are somewhat darker than in the above embodiment.

As shown in FIG. 7(c), when only the first lamp unit 20A is turned on, the vehicle lamp 210 appears to have only the first light-transmitting area Za shining with a substantially uniform brightness. At that time, the intermediate area 14c of the light-transmitting cover 14 prevents light from leaking from the first lamp unit 20A to the second lamp unit 20B, so the second light-transmitting area Zb does not appear to be shining dimly.

Similarly, as shown in FIG. 7D, in the vehicle lamp 210 in which only the second lamp unit 20B is in a lit state, only the second light-transmitting region Zb appears to shine with substantially uniform brightness. At this time, since light leakage from the second lighting unit 20B to the first lighting unit 20A side is prevented in the intermediate region 14c of the light-transmitting cover 14, the first light-transmitting area Za does not appear to shine dimly. do not have.

Even when the configuration of this modification is adopted, the manufacturing cost of the vehicle lamp 210 can be suppressed and the appearance can be improved.

Moreover, in this modification, since the first light-shielding film 16 is covered with the colored film 230 formed on the front surface 14a of the light-transmitting cover 14, a part of the light-transmitting cover 14 is covered with the first light-shielding film 16 when the light is not lit. The color of the colored film 230 (that is, white) can be made visible without being visible as the color of the colored film 230 (that is, black), and thereby the appearance of the vehicle lamp 10 can be improved.

In this case, in this modification, the colored film 230 is formed over the entire area of the front surface 14a of the light-transmitting cover 14, so that when the light is not lit, not only the first light-shielding film 16 but also the first and second lamp units 20A , 20B are also made invisible, while when either or both of the first and second lighting units 20A and 20B are lit, the portions of one or both of the first and second light-transmitting areas Za and Zb are made invisible. The chisel can be made to appear circular and brightly shining.

In the second modification described above, the colored film 230 has been described as being made up of a white paint film, but it is also possible to make it make up of a paint film other than white (for example, light blue or cream color). It is.

Next, a third modification of the above embodiment will be described.

FIG. 8 is a diagram similar to FIG. 4, showing a vehicle lamp 310 according to this modification.

As shown in FIG. 8, the basic configuration of this modification is the same as that of the second modification, but the configurations of the first and second lighting units 320A and 320B are different from those of the second modification. Accordingly, the configurations of the first and second packings 328A and 328B are also different from those of the second modification.

The first lamp unit 320A has a first reflector 324A with a reflective surface 324Aa formed in two levels, one above the other, and a first light source 22A similar to that of the second modified example is disposed on each level.

Each reflective surface 324Aa has the same reflective surface shape as the reflective surface 24Aa of the second modification, but its outer shape is set to a horizontally long rectangular shape.

A first packing 328A similar to the first packing 28A of the second modified example is disposed between the first reflector 324A and the translucent cover 14, but this first packing 328A is formed to extend in a rectangular ring shape along the front end surface of the first reflector 324A.

Similarly to the first lighting unit 320A, the second lighting unit 320B also has a reflecting surface 324Ba of its second reflector 324B formed in two stages, upper and lower, each of which is provided with a second light source similar to the second modification. 22B is arranged. The configuration of each reflective surface 324Ba is similar to the reflective surface 324Aa of the first reflector 324A. Furthermore, a second packing 328B having a bilaterally symmetrical shape with the first packing 328A is arranged between the second reflector 324A and the light-transmitting cover 14.

As a result, in the vehicle lamp 310 according to this modified example, the vertically long rectangular area located on the inner periphery of the first packing 328A constitutes a first light-transmitting area Za through which the light emitted from the first lamp unit 320A passes through the light-transmitting cover 14, and the vertically long rectangular area located on the inner periphery of the second packing 328B constitutes a second light-transmitting area Zb through which the light emitted from the second lamp unit 320B passes through the light-transmitting cover 14.

As shown in FIG. 8(a), in the vehicle lamp 310 in which the first and second lamp units 320A and 320B are in the non-lighting state, the front surface 14a of the transparent cover 14 is The colored film 230 formed over the entire area appears white, and the first light shielding film 16 and the first and second lamp units 320A and 320B are not visible.

On the other hand, as shown in FIG. 8B, the vehicle lamp 310 in which the first and second lamp units 320A and 320B are in the lighting state has first and second light-transmitting regions on both left and right sides of the first light-shielding film 16. Za and Zb have rectangular shapes and appear to shine. At this time, the first and second light-transmitting regions Za and Zb have substantially uniform brightness and appear to shine brighter than in the second modification.

As shown in FIG. 8(c), when only the first lamp unit 320A is turned on, the vehicle lamp 310 appears to have only the first light-transmitting area Za shining with a substantially uniform brightness. At this time, the intermediate area 14c of the light-transmitting cover 14 prevents light from leaking from the first lamp unit 320A to the second lamp unit 320B, so the second light-transmitting area Zb does not appear to be shining dimly.

Similarly, as shown in FIG. 8D, in the vehicle lamp 310 in which only the second lamp unit 320B is in a lit state, only the second light-transmitting region Zb appears to shine with substantially uniform brightness. At this time, since light leakage from the second lighting unit 320B to the first lighting unit 320A side is prevented in the intermediate region 14c of the light-transmitting cover 14, the first light-transmitting area Za does not appear to shine dimly. do not have.

Even when the configuration of this modification is adopted, it is possible to reduce the manufacturing cost of the vehicle lamp 310 and to improve the appearance.

Furthermore, in this modification, the first and second reflectors 324A and 324B of the first and second lighting units 320A and 320B are provided with reflective surfaces 324Aa and 324Ba formed in two stages, upper and lower, and Since the first and second light sources 22A and 22B are arranged, when one or both of the first and second lighting units 20A and 20B are turned on, neither of the first and second light-transmitting areas Za and Zb is illuminated. Only one or both portions can appear to shine in a rectangular shape, and in this case, it can be made to appear to shine with substantially uniform brightness and in a brighter state than in the case of the second modification.

Note that the numerical values shown as specifications in the above embodiment and its modified examples are merely examples, and it goes without saying that these may be set to different values as appropriate.

Furthermore, the present invention is not limited to the configurations described in the above-described embodiments and modifications thereof, and configurations with various other changes can be adopted.
