Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a functional color of a lamp when it is lit (here, the functional color is a lamp color that is approved by the JIS standard for each type of lamp, It is a concept including white) It emits light, and relates to a vehicle lamp that looks like a color other than the functional color of the lamp when it is not illuminated.

[Prior Art] There is known a vehicle lighting device that emits a functional color when the lamp is lit and looks like a color other than the functional color when the lamp is not lit to obtain a novel image.

As a lamp of this type, firstly, as shown in FIG.
As shown in (b), there is known a lamp in which the colored layer 3 is formed in a slit shape or a mesh shape on the surface of the front lens 2 by painting or molding an opaque resin.

Secondly, as shown in FIGS. 7 (a) and 7 (b), the surface coloring layer 5 is formed into a slit shape or a mesh shape by coating.
There is known a lamp in which an inner lens 4 having a lens is arranged between the front lens 2 and the bulb 6. Thirdly, as shown in FIGS. 8 (a) and 8 (b). In addition, a lamp is known in which a tape 7 or the like printed in a predetermined color is attached to the back surface of the front lens 2 in a slit shape or a mesh shape. 6 to 8, reference numeral 1 is a lamp body, and reference numeral 6 is a bulb.

[Problems to be solved by the device]

However, the above-described conventional lamp structure has the following problems.

In the first method, the coating applied to the outer surface requires several repeated coatings in consideration of durability, which is very troublesome. Further, in the case of molding an opaque resin, the molding is performed integrally with the front lens, and the number of molding steps increases and the cost increases.

In addition, the second type requires an inner lens that is a second lens in addition to the front lens, and this inner lens must be coated so that the cost becomes high.

The third type has a problem that it is easily peeled off and lacks reliability because a tape or the like is attached.

Furthermore, in the first and third examples, the colored layer clearly appears on the front lens, and the appearance is not good. Particularly, in the case of the first type, unevenness due to the coating thickness appears on the front lens surface, which is not preferable in terms of appearance.

The present invention has been made in view of the above-mentioned problems of the prior art,
An object of the present invention is to provide a vehicle lighting device that has a simple structure, has a good appearance, and emits a functional color when turned on, but looks like a color other than the functional color when not turned on.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, in the vehicle lighting device according to the present invention, a diffusion step is formed between a front lens having a functional color and a light source, and a light different in color from the front lens is substantially emitted. With an opaque colored plate that cannot be transmitted, an opening for transmitting light from the light source is formed in this colored plate, and when it is lit, it emits light in the functional color of the front lens,
When not lit, the colored plate and the front lens appear to be a mixed color.

[Action]

With a simple structure in which an opaque colored plate with an opening is simply placed in the lamp, the light source light that has passed through the opening emits a single functional color when lighting, and when not lighting, the functional color of the front lens and the coloring plate It looks like a single color that overlaps with the color. Moreover, since the colored plate is not exposed to the outside, the appearance is good.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

1 to 5 show the combination of the present invention applied to a rear combination lamp, and FIG. 1 is a front view of a combination lamp (left side combination lamp) in which a tail & stop lamp, a turn signal lamp and a backup lamp are integrated. , Fig. 2 is its horizontal sectional view, Fig. 3
5 to 5 are vertical sectional views.

In these figures, reference numeral 10 is the lamp body of the left combination lamp, that is, the tail and stop lamp lamp body 10a and the turn signal lamp lamp body 10b.
And the lamp body 10c of the backup lamp is configured integrally, and by the shade 12 extending in the lamp body 10 in the vertical and horizontal directions, in the upper region of the lamp body 10, a lamp chamber 11a for the tail & stop lamps extending in the left and right, Light room 1
A lamp chamber 11b for a turn signal lamp extending in an L shape is formed on the left side of 1a, and a lamp chamber 11c for a backup lamp located directly below the lamp chamber 11a is formed.

A bulb 12a, which is a light source, is provided in each lamp body 10a-10c.
~ 12c is installed. Two lamps 12a ₁ and 12a ₂ are provided in parallel in the lamp body 10a of the tail and stop lamp, and a reflector 14 is provided so as to surround the respective bulbs 12a ₁ and 12a ₂ . Also the lamp body
A seal groove 15 is formed in the peripheral edge of the front opening of 10 and the front end of the shade 12, and in this seal groove 15,
A front lens 16 in which front lenses 16a, 16b, 16c of colors according to respective lamp functions are integrated is assembled. Code 15
a is a sealant.

The lens 16a is a reddish transparent outer lens for a tail and stop lamp, and an inner lens 17a is arranged inside thereof. Reference numeral 18 is a reflex reflector formed in a belt shape at a predetermined interval in the vertical direction.

The lens 16b is a front lens for a transparent turn signal lamp that is tinged with amber and has a length that extends over the entire left-right direction of the lamp body 10, and an area corresponding to the lamp chamber 11c of the backup lamp is opened. A front lens 16c for a white backup lamp is attached to the part. An inner lens 17b having the same curvature as that of the lens 16b is arranged inside the lens 16b in the lamp chamber 11b. A region 11d adjacent to the right side of the lamp chamber 11c of the lamp body 10 is a dummy region in which no bulb is provided.

Further, on the back side of the front lens 16c for the backup lamp, an opaque colored plate 20 of amber color, which is substantially impenetrable to light, is supported by the shade 12 at both left and right leg portions of the shade 12 with a certain gap from the lens 16c. It is arranged. The colored plate 20 is formed with upper and lower slits 22a and 22b which are openings extending in the left-right direction, and the light of the bulb 12c is directed to the lens 16c side through the slits 22a and 22b. Further, on the back surface of the lens 16c, a fish-eye step 30 which is a diffusion step is formed, and a predetermined light distribution is obtained by the light transmitted through the front lens 16c, and when not illuminated, the coloring plate 20 causes the front lens 16c. It seems to spread all over.

Therefore, in the backup lamp, when the bulb is lit, a part of the light of the bulb 12c is reflected by the coloring plate 20, but most of the light of the bulb 12c is slits 22a, 22b of the coloring plate 20.
After passing through the front lens 16c, white light is emitted to the front. Further, when the bulb is not lit, the amber color of the colored plate 20 appears on the front lens 16c. In particular, by partially forming the fish-eye step 30 as a lens step having a stronger diffusion property, the color of the coloring plate 20 is diffused, and the front lens 16c looks as if it is the same color as the coloring plate. When the lamp is not lit, the lenses 16b and 16c look like a substantially uniform amber color, so that the turn signal lamp and the backup lamp have a sense of unity in color, and the combination lamp has a calm hue.

In the above-described embodiment, the backup lamp region is formed in the lamp body region of the turn signal lamp, the present invention is applied to this backup lamp, and the front lens is white and the colored plate is amber. May be yellow, and the colored plate having the slits may be red, and the red color of the colored plate may be diffused when not lit to cause the front lens to appear amber, and the pale yellow light may be emitted when lit.

Also, in the case of a combination lamp in which a backup lamp area is formed in the lamp body area of the tail & stop lamp, the front lens of the backup lamp is white,
The colored plate having the slits may be the same red color as the functional color of the tail and stop lamp.

Further, in the above-mentioned embodiment, an embodiment in which the present invention is applied to a backup lamp has been described, but the present invention can also be applied to a turn signal lamp. In this case, the front lens (outer lens) is a tail and stop lamp. The same color as the functional color of the above, and the amber color on the coloring plate, the front lens looks like amber near red when not lit, giving a sense of unity with the tail & stop lamps, and the amber color which is the functional color when lit It may be emitted. In this case, the colored plate may be white and the bulb may be colored yellow. In addition, various combinations are conceivable as long as the same effect as the present invention can be obtained.

[Effect of device]

As is clear from the above description, according to the vehicle lamp of the present invention, when the lamp is lit, the functional light of the front lens is colored with the functional color of the front lens when it is not lit by the light transmitted through the opening of the coloring plate. Since it looks like a single color other than the functional color that overlaps with the color of the board, a novel image can be obtained.

Further, since the opaque colored plate having the opening is simply arranged in the lamp, the cost is excellent, and the colored plate is not exposed to the outside, so that the appearance is excellent.
