Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combination lamp having adjacently illuminated lamps of different colors, and more particularly to a combination for a vehicle configured so that adjacent lamps look the same color when the lamp is not lit. About the lamp.

[0002]

2. Description of the Related Art A combination lamp disposed at the rear of a vehicle is formed by arbitrarily combining a tail & stop lamp, a backup lamp, and a turn lamp.
Normally, when lit, the tail & stop lamp is red,
The backup lamp is configured to emit white light, and the turn lamp is configured to emit orange light. Therefore, a color corresponding to the bulb which is a light source of each lamp and a lens arranged in front of the bulb are selected. For example, tail and stop lamps have the lens itself red. The backup lamp uses white light for the bulb and makes the lens colorless, and the turn lamp uses orange light for the bulb and makes the lens colorless.

In this type of combination lamp, the tail & stop lamp of the red lens has a large area as a whole, and the backup lamp and the turn lamp are relatively small. Therefore, when the combination lamp is viewed in the daytime when the lamp is not turned on, a relatively small colorless lens in the red-based lens group looks white and conspicuous. Therefore, when the lamp is not lit,
It is considered that the appearance of the automobile is better when the colors of the various lamps are unified to the same color. Therefore, attempts have been made to make the entire combination lamp look the same color when not lit.

For example, Japanese Utility Model Laid-Open No. 2-101404 discloses one of such attempts. This technology is used in a vehicle lighting device in which a front lens is made up of a plurality of different color lenses, and one of the different color lenses has the same color as the other different color lens, including a junction with the other different color lens. The sheet is covered with a color sheet, and the sheet is provided with a plurality of light transmitting windows. Thereby, in this example, it is described that the joint portion of the different color lens can be hidden and the lens color can be unified to the other lens color.

[0005]

The prior art simply covers one of the different color lenses with a sheet of the same color as the color of the other different color lens. Moreover, since a plurality of light-transmitting windows are provided on this sheet, a part of the lens can still be seen as it is. For example, if one of the different color lenses is for a colorless backup lamp and the other is for a red tail and stop lamp, then even if the colorless lens is covered with a red sheet,
A part of the colorless lens looks whitish through the translucent window of the sheet. Therefore, in the conventional vehicle lamp, there is a problem that one of the different color lenses cannot be made a color sufficiently unified with the other lens color.

Accordingly, it is an object of the present invention to provide a combination lamp in which a plurality of adjacent lamps look the same color when not lit.

[0007]

An object of the present invention is to provide a combination lamp in which a first lamp having a first lens on the front surface and a second lamp having a second lens on the front surface are provided adjacent to each other. A second lamp, a reflector having a high reflectivity, a bulb disposed on a reflection surface side of the reflector, and emitting light of a color different from the color of the first lens;
This is attained by a combination lamp provided with an opaque pattern portion disposed in front of the bulb and having the same color as the color of the first lens.

Here, a reflector having a high reflectance of 70% or more, preferably 90% or more is used. The first in the opaque pattern portion
The same color as the color of the lens is a concept including a color that can be said to be the same color, and does not need to be exactly the same color. For example, when the color of the first lens is red, it is desirable that the color of the opaque pattern portion is exactly the same red color, but it is sufficient if the color is at least red. Further, this pattern portion is printed or affixed, for example, on the rear surface of the second lens, but may be arranged between the second lens and the bulb.

By configuring the second lamp in this manner, a lamp based on a completely new concept that, when the lamp is not lit, the color due to the reflection of the colored opaque pattern portion is visible, and when the lamp is lit, the luminescent color of the bulb is visible. Can be obtained.

When this combination lamp is viewed from the rear of the vehicle, when the second lamp is not lit, the opaque pattern portion of the same color as the color of the first lens has the high reflectance of the second lamp. The light is reflected by the reflector, and the reflected light of the color of the pattern portion is seen through the non-pattern portion. And
When the second lamp is turned on, light from a bulb that emits light of a color different from the color of the first lens is directly or reflected by a reflector having a high reflectance, and is seen through a non-pattern portion. For example, if the first lamp is a tail and stop lamp having a red lens and the second lamp is a backup lamp having a red opaque pattern portion and a bulb that emits white light, the backup lamp is not lit. At times, the entire combination lamp looks red, and when the backup lamp is lit, the backup lamp portion looks white and the other portions look red. As described above, according to the present invention, a plurality of adjacent lamps can be made to look the same color when not lit.

[0011]

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

FIG. 1 is a diagram showing the appearance of the rear part of the vehicle.
As shown in the figure, a tail and stop lamp 2 having a large area and a backup lamp 3 having a relatively small area are arranged as a combination lamp in the rear portion of the vehicle 1. When the lamp is turned on, the tail & stop lamp 2 emits red light and the backup lamp 3 emits white light.

FIG. 2 is an enlarged view showing the appearance of the combination lamp. As shown, a backup lamp 3 is arranged in the middle of the tail & stop lamp 2. The backup lamp 3 is provided with a pattern section 31.

FIG. 3 is a diagram showing a cross section taken along the line AA 'of FIG. As shown in the example, the tail & stop lamp 2
Are arranged at two places on both sides of the backup lamp 3. The upper tail and stop lamp 2 has a red lens 21 provided on the front of the lamp, a bulb 22 provided inside the lamp, and a reflector 23 for reflecting light emitted from the bulb 22. Similarly, the stop lamp 2 has a red lens 24 provided on the front of the lamp.
And a bulb 25 provided inside the lamp;
And a reflector 26 that reflects the light emitted by the light source. Thus, when lit, the upper and lower tail and stop lamps 2 emit red light.

On the other hand, the backup lamp 3 includes a colorless lens 32 provided on the front surface of the lamp, a reflector 34 having a high reflectance, a bulb 33 for emitting white light disposed on the reflection surface side of the reflector 34, and a bulb. 33, and a red pattern portion 31 provided in front of 33. The red pattern portion 31 is opaque, for example, a lens 32
Is formed by hot stamping on the back surface of. The surface of the reflector 34 is formed by, for example, aluminum evaporation, and the reflectance is as high as about 90%. Incidentally, when the reflector is made of silver paint, the reflectance is as low as about 60%, which is insufficient to make adjacent lamps appear the same color when not lit. Therefore, it can be said that the surface treatment of the reflector 34 is preferably performed by, for example, aluminum evaporation, which can provide a high reflectance. Since the brightness inside the lamp varies depending on the weather or time, the reflector can project a red pattern even when the reflectance is low in sunny weather (when the outside is bright), but in rainy weather or at sunset ( When the outside is dim, the red pattern cannot be projected without a certain degree of reflectance. Considering these, the reflector 34 has a reflectance of 70% or more,
Preferably, it is 90% or more.

When the combination lamp thus configured is viewed from the rear of the vehicle, when the backup lamp 3 is not lit, the red opaque pattern portion 31 is reflected by the reflector 34 having a high reflectance, and this pattern portion is reflected. 31
Is reflected through the non-pattern portion 35. When the backup lamp 3 is turned on, white light from the bulb is reflected directly or on a reflector 34 having a high reflectance, and is seen through a non-pattern portion 35. Thus, when the backup lamp 3 is not lit, the entire combination lamp looks red and the backup lamp 3
Is lit, the backup lamp 3 is white.
Other parts become red.

FIG. 4 is a diagram showing another embodiment of the backup lamp 3. In the present embodiment, the surface shape of the reflector 36 is devised in accordance with the pattern of the pattern portion 31 so that the red light reflected by the pattern portion 31 is emitted more to the outside. This reflector 36
Has a surface shape of, for example,
It can be manufactured by applying the structure of the reflecting surface portion disclosed in Japanese Patent Application Laid-Open No. 5-105.

FIG. 5 is a view showing still another embodiment of the backup lamp 3. As shown in FIG. In this embodiment, the opaque pattern portion 37 is arranged not on the back surface of the lens 32 but between the lens 32 and the bulb 33. Pattern part 37
Can be manufactured by printing an opaque red pattern on a transparent plate, for example.Another method is to form an opening in the opaque red plate, and It can also be manufactured by forming the part 38. The shape of the pattern of the pattern portion 37 is not limited, but a strip shape as shown in FIG. 2 can be used. The ratio between the pattern portion and the non-pattern portion is determined in consideration of the amount of light required as a backup lamp.

By doing so, when the backup lamp is not lit, the combination lamp looks red as a whole, and when the backup lamp is lit, only the backup lamp portion looks white.
Therefore, a sense of unity is produced in the combination lamp when it is not lit, and a lamp excellent in appearance can be obtained. Also, a new appearance can be obtained due to the difference in the depth of the red color reflected on the reflector of the backup lamp and the red color on the lens surface.

In the above description, an example of a combination of a tail & stop lamp and a backup lamp has been described as a combination lamp, but a turn lamp can be combined with the backup lamp instead of the backup lamp or together with the backup lamp. In this case, generally, the bulb of the turn lamp is orange light, and the color of the lens is colorless. Further, the ratio of the opaque pattern portion to the non-pattern portion of the turn lamp is determined in consideration of the turn effective light emitting area.
