Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicular marker lamp in which a plurality of diffuse reflection surface elements are formed on a reflection surface of a reflector.

[0002]

2. Description of the Related Art Recently, so-called diffusion step reflectors, in which a plurality of diffuse reflection surface elements are formed on a reflection surface, are often used in vehicle marker lights.

[0003] Generally, the diffusion step reflector is
As shown in FIG. 16, each of a plurality of strip-shaped segments SG 'formed by dividing the reflecting surface 6a into vertical stripes has a cylindrical reflecting surface element (diffuse reflecting surface element) 6s.
Are assigned, and the light from the bulb 2 is diffused and reflected in the left-right direction by the cylindrical reflecting surface elements 6s.

In the marker lamp provided with such a diffusion step reflector 6, only the light incident on one point in the left-right direction of the cylindrical reflecting surface element 6s among the light incident on each of the cylindrical reflecting surface elements 6s is described. The light will be reflected toward the front of the lamp. For this reason, when the lighting fixture in the lighting state is observed from the front, as shown in FIG.
Each of the cylindrical reflecting surface elements 6s is provided with the reflecting surface 6s.
The bright portion Br 'extends linearly from the upper end to the lower end of "a".

[0005]

However, in such a marker lamp provided with the diffusion step reflector 6 such that the vertical stripe-shaped brilliant portions Br 'can be seen side by side at a predetermined interval in the left-right direction, the lighting state of the marker lamp is reduced. There is a problem that a person who observes a certain lamp from the front cannot sufficiently give a feeling that the reflection surface 6a is shining (glitter), and the appearance of the lamp cannot be enhanced much.

[0006] The present invention has been made in view of such circumstances, and an object of the present invention is to provide a marker light for a vehicle, which can improve the appearance at the time of lighting in a marker light having a diffusion step reflector. It is the purpose.

[0007]

SUMMARY OF THE INVENTION The present invention is intended to achieve the above object by improving the glitter of the reflecting surface by devising the arrangement of the segments to which the respective diffuse reflecting surface elements are allocated. .

That is, according to the present invention, as described in claim 1, a reflector having a reflecting surface for reflecting light from the bulb and having a plurality of diffuse reflecting surface elements formed on the reflecting surface is provided. In the vehicular marker lamp, each of the diffuse reflection surface elements further divides each of the plurality of band-shaped segments formed by dividing the reflection surface into stripes in a direction orthogonal to the stripes. It is allocated to each of the plurality of formed rectangular segments, and a boundary between the rectangular segments in each of the strip-shaped segments is set at a different position between adjacent strip-shaped segments. It is assumed that.

The directions of the stripes generated by the plurality of strip-shaped segments (hereinafter referred to as “band-shaped segment generation stripes”) and the stripes orthogonal to the strip-shaped segment generation stripes (hereinafter referred to as “rectangular segment generation stripes”) are as follows. There is no particular limitation, and the band-shaped segment generation stripes are vertical stripes and the rectangular segment generation stripes are horizontal stripes,
Any of a configuration in which the band-shaped segment generation stripes are horizontal stripes and the rectangular segment generation stripes are vertical stripes, and a configuration in which the band-shaped segment generation stripes and the rectangular segment generation stripes are oblique stripes can be adopted.

[0010] The "plurality of band-shaped segments" may be formed at an equal pitch or at an unequal pitch.
Similarly, the “plurality of rectangular segments” in each of the strip-shaped segments may be formed at an equal pitch or at an irregular pitch.

The surface shape of each of the “diffuse reflection surface elements” is as follows:
The surface shape is not particularly limited as long as it is a surface shape other than the surface shape that diffuses the light from the bulb only in the direction of the rectangular segment generation stripes.

[0012]

As described above, according to the present invention, each diffuse reflection surface element constituting the reflection surface of the reflector is allocated to each of the plurality of rectangular segments constituting each of the plurality of strip-shaped segments. And, since the boundaries between the respective rectangular segments in the respective band-shaped segments are set at different positions between the adjacent band-shaped segments, when the lighting fixture in the lighting state is observed from the front, Each of the above-mentioned diffuse reflection surface elements appears to be shining at a different position between adjacent strip-shaped segments, thereby giving a sufficient glitter to the observer.

Therefore, according to the present invention, it is possible to improve the appearance at the time of lighting in a sign lamp provided with a diffusion step reflector.

In the above structure, the plurality of rectangular segments in each of the strip-shaped segments are formed at equal pitches in the front view of the lamp, and each of the boundary lines is connected to the adjacent strip-shaped segment. If the lamps are set at positions shifted by a half pitch from each other, when the lit lamp is observed from the front, the above-mentioned diffuse reflection surface elements appear to shine in a staggered arrangement, so that the observer is in harmony with glitter. A feeling can be given, whereby the appearance of the lamp at the time of lighting can be further improved.

Alternatively, in the above configuration, as described in claim 3, if the plurality of rectangular segments in each of the band-shaped segments are formed at a gradually changing pitch when viewed from the front of the lamp, the lighting state is established. When the lamp is observed from the front, each of the diffuse reflection surface elements appears to shine while gradually changing the width of the dark portion in each of the strip-shaped segments, and thus gives the observer a three-dimensional effect (or a sense of depth) together with a glittering effect. Thus, the appearance of the lamp at the time of lighting can be further improved.

In this case, the specific aspect of the "gradually changing pitch" is not particularly limited, and the pitch of the rectangular segment monotonically increases (or monotonically decreases) toward one end of the lamp. The pitch of the rectangular segments may monotonically increase (or decrease monotonically) toward both end portions of the lamp, or the pitch of the rectangular segments may be repeatedly increased and decreased. It may be something.

In this case, the "gradually changing pitch" may be set to be the same for all of the plurality of band-shaped segments, or the "gradually changing pitch" may be set to be different for each band-shaped segment. May be set.

In the above configuration, the "plurality of diffuse reflection surface elements" may be formed of a curved surface having a curvature different from that of the single curved surface while referring to a single curved surface such as a paraboloid of revolution. As described in claim 4, a plurality of paraboloids of revolution having the same axis and different focal lengths, wherein at least some of the plurality of diffuse reflecting surface elements have a common focal point at a predetermined fixed point. By using a curved surface having a curvature different from that of the paraboloid of revolution with reference to the above, it is possible to obtain a reflector shape corresponding to the space in which the lamp is provided. For example,
If the plurality of paraboloids of revolution are set to a paraboloid of revolution having a longer focal length as being farther away from the axis, the reflector can be made thinner. Conversely, the plurality of paraboloids of revolution can be reduced. If the object surface is set to be a paraboloid of revolution having a shorter focal length as being farther from the axis, a reflector having a greater depth can be obtained.

As described above, the surface shape of each "diffuse reflection surface element" is not particularly limited except for a specific exceptional surface shape. For example, it is formed in a fish-eye shape or a cylindrical shape. It is possible. that time,
As described in claim 5, the "each diffuse reflection surface element"
Is constituted by a cylindrical reflecting surface element extending in the same direction as the rectangular segment generating stripes, a plurality of brilliant portions shining in a barcode shape are formed in a plurality of stages in each of the strip-shaped segments, so that the reflecting surface Can be further enhanced. In this case,
The cross-sectional shape of the “cylindrical reflecting surface element” may be convex or concave, or may be a wave shape combining these.

By the way, in a vehicular marker lamp, a lens is usually provided in front of the reflector. In the present invention, this lens may be a plain lens or a lens in which a lens step is formed. Good. At this time, when each of the diffuse reflection surface elements is constituted by a cylindrical reflection surface element extending in the same direction as the rectangular segment generation stripes as described in claim 5, it is described in claim 6. As described above, if the lens is configured to have a plurality of diffusion lens steps, and each of these diffusion lens steps is configured by a cylindrical lens step extending in the same direction as the strip-shaped segment generation stripes, as a lamp, from the bulb Light can be diffused in the vertical and horizontal directions. In this case, the cross-sectional shape of the “cylindrical lens step” may be a convex shape, a concave shape, or a wave shape combining these.

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

First, a first embodiment of the present invention will be described.

FIG. 1 is a front view showing a vehicle marker light according to the present embodiment, and FIGS. 2 and 3 are sectional views taken along lines II-II and III-III, respectively.

As shown in these figures, a marker lamp (lamp) 10 according to the present embodiment is a tail lamp provided at a rear end portion of a vehicle body of an automobile, and includes a bulb 12 having a vertically extending filament 12a, A reflector 16 that supports the bulb 12 via a socket 14 and diffuses and reflects light from the bulb 12 forward (forward as a lamp and backward as a vehicle body, the same applies hereinafter), and a reflector 16 in front of the reflector 16 And a lens 18 fixed to the reflector 16 and has a rectangular outer shape that is long on the left and right.

FIG. 4 shows the marker lamp 10 with its lens 18
It is a front view which removes and shows.

As shown in the figure, the reflector 16 has a plurality of diffuse reflection surface elements 16s formed over the entire reflection surface 16a. Each of the diffuse reflection surface elements 16s has a plurality of (five) band-shaped segments SG formed by dividing the reflection surface 16a into a horizontal stripe.
Are further assigned to each of a plurality of rectangular segments sg formed by further dividing each of them into vertical stripes.

The plurality of strip-shaped segments SG are formed at an equal pitch when viewed from the front of the lamp. Although the plurality of rectangular segments sg are also formed at equal pitches in each of the band-shaped segments SG in the lamp front view,
A boundary line b between the rectangular segments sg in each of the strip segments SG is set at a position shifted by a half pitch between the adjacent strip segments SG.

As is clear from FIGS. 2 and 3, each of the diffuse reflection surface elements 16s is connected to the optical axis A of the reflector 16.
It is composed of a curved surface having a different curvature from the paraboloid of revolution with reference to the paraboloid of revolution centered at x. That is,
Each of the diffuse reflection surface elements 16s is constituted by a convex cylindrical reflection surface element extending in the vertical direction, and thereby diffuses and reflects light from the bulb 12 in the left and right direction around the optical axis Ax direction. It is made to let.

FIG. 5 is a view showing how the reflecting surface 16a is viewed from the front of the lamp when the bulb 12 is turned on.

As shown in FIG.
Since s has a left-right diffusion function, each of the diffuse reflection surface elements 16s appears to shine as a vertical streak-like bright portion Bro by the light reflected from the diffuse reflection surface element 16s. Then, as the entire reflecting surface 16a, a plurality of brilliant portions Bro shining at substantially equal pitches to the left and right are formed over a plurality of upper and lower stages in a state of being shifted by a half pitch, and thus appear to shine in a staggered arrangement.

As shown in FIG. 2 and FIG.
On the inner surface of 8, a plurality of diffusion lens steps 18s are formed. Each of the diffusion lens steps 18s is formed of a concave cylindrical reflection surface element extending in the left-right direction, and thereby diffuses the left-right diffusion reflection light from the reflection surface 16a in the vertical direction. The pitch of the plurality of diffusion lens steps 18s is:
The pitch is set equal to ピ ッ チ of the pitch of each of the strip-shaped segments SG, and the boundaries are set at the same height as every other strip-shaped segment SG. ing.

FIG. 6 shows how the reflecting surface 16a is viewed from the front of the lamp when the bulb 12 is turned on in a state where the lens 18 is put on the reflector 16 (that is, the state as the lamp 10). FIG.

As shown in the figure, since each of the diffusion lens steps 18s has a vertical diffusion function, each of the diffuse reflection surface elements 16s divides the brilliant portion Bro into upper and lower portions, and furthermore, the vertical length thereof is reduced. It appears as a pair of upper and lower brilliant portions Br1 that have been shortened. Then, the reflection surface 16a
As a whole, a pair of upper and lower brilliant portions Br1 shining at substantially equal pitches to the left and right are formed over a plurality of upper and lower stages in a state shifted by a half pitch.

As described in detail above, in the present embodiment, each of the diffuse reflection surface elements 16s constituting the reflection surface 16a of the reflector 16 is formed by dividing the reflection surface 16a into horizontal stripes. Strip segment S
G is composed of vertically extending cylindrical reflecting surface elements allocated to each of a plurality of rectangular segments sg formed by further dividing each of the vertical segments into vertical stripes, and the rectangles in the strip segments SG. Since the boundary line b between the segments sg is set at a different position between the adjacent strip-shaped segments SG, when the lamp 10 in the lighting state is observed from the front with the lens 18 removed, Each diffuse reflection surface element 16s appears to shine as a vertical streak-like brilliant portion Bro at a different position between adjacent strip-shaped segments SG, thereby giving a sufficient glitter to the observer.

Further, in the present embodiment, when viewed from the front of the lamp, the plurality of rectangular segments sg in each of the strip-shaped segments SG are formed at an equal pitch. Since the segments SG are set at positions shifted by half a pitch between the segments SG, when the lamp 10 in the lighting state is observed from the front with the lens 18 removed, the vertical stripe-shaped bright portions Bro are staggered. This gives the observer a sense of harmony as well as glitter.

In the present embodiment, since a plurality of diffusion lens steps 18s composed of cylindrical lens steps extending in the horizontal direction are formed on the inner surface of the lens 18, the lamp 10 in a lighting state can be observed from the front. Then, each of the brilliant portions Bro shines as a pair of short vertical streak-like brilliant portions Br1 in the upper and lower portions, and the brilliant portions Br1 appear to shine in a zigzag arrangement as a whole lamp, thereby giving the observer a sense of glitter and harmony. A new impression can be given with it.

As described above, according to the present embodiment, it is possible to improve the appearance of the marker lamp provided with the diffusion step reflector at the time of lighting.

In the present embodiment, since each of the diffuse reflection surface elements 16s constituting the reflection surface 16a is formed of a convex cylindrical reflection surface element, the diffuse reflection surface element 16s extends right and left from the front of the lamp (in front of the optical axis Ax direction). When the reflection surface 16a is observed by shifting the viewpoint, each bright portion Bro in FIG.
(Or each bright portion Br1 in FIG. 6) shines in substantially the same arrangement while being displaced in a direction shifted from the viewpoint, but since each diffusion lens step 18s of the lens 18 is formed of a concave cylindrical lens step, In FIG. 6, when the reflecting surface 16a is observed by shifting the viewpoint up and down from the front of the lamp, the bright portions Br1 shine in substantially the same arrangement while being displaced in the direction opposite to the direction in which the viewpoint is shifted. Therefore, when the observation is performed while appropriately shifting the viewpoint from the front side of the lamp, the arrangement of the brilliant portions Br1 changes in two directions, so that the observer can be given a stronger glittering feeling.

Next, a second embodiment of the present invention will be described.

FIG. 7 is a front view showing a vehicle marker light according to the present embodiment, and FIG. 8 is a sectional view taken along line VIII-VIII of FIG.

As shown in these figures, the basic configuration of this embodiment is the same as that of the first embodiment,
The pitch of the plurality of diffusion lens steps 18s formed in the first embodiment is different from that in the first embodiment.

That is, the diffusion lens steps 18s located on the optical axis Ax are formed at the same pitch as the vertical width of the diffuse reflection surface element 16s, but the pitch gradually increases as the distance from the optical axis Ax increases in the vertical direction. Is formed to be narrow.

For this reason, in the present embodiment, as shown in FIG. 9, when the lamp 10 in the lighting state is observed from the front, each of the brilliant portions Bro shown in FIG. It shines as a plurality of brilliant portions Br1, and the brilliant portions Br1 appear to shine in a staggered arrangement as a whole lamp. Thus, it is possible to give the observer a glittering feeling with a more novel impression than in the first embodiment.

Next, a third embodiment of the present invention will be described.

FIG. 10 is a side sectional view showing a vehicle marker light according to this embodiment.

As shown, in the present embodiment, the plurality of diffuse reflection surface elements 16s constituting the reflection surface 16a of the reflector 16 are not cylindrical reflection surface elements, but
The third embodiment differs from the first embodiment in that the first embodiment is configured by a convex fish-eye reflecting surface element and the lens 18 is formed by a transparent lens. However, each of the diffuse reflection surface elements 16
As in the first embodiment, s is a plurality of rectangular segments sg formed by further dividing each of the plurality of strip-shaped segments SG formed by dividing the reflection surface 16a into horizontal stripes into vertical stripes. Assigned to each.

In this embodiment, since each of the above-mentioned diffuse reflection surface elements 16s is constituted by a fish-eye reflection surface element, as shown in FIG.
The light reflected by the diffuse reflection surface element 16s appears as a spot-shaped bright portion Bro. Then, as the entire reflecting surface 16a, a plurality of spot-shaped brilliant portions Bro shining at substantially equal pitches to the left and right are formed over a plurality of upper and lower stages in a state shifted by half a pitch, so that they appear to shine in a staggered arrangement. .

Since the lens 18 of this embodiment is transparent, when the lamp 10 with the lens in the lit state is observed from the front, the plurality of spot-shaped luminous rays are similar to the appearance shown in FIG. The section Bro appears to be shining in a staggered arrangement as it is, thereby giving the observer a sense of harmony as well as glitter with an impression different from that of the first embodiment.

Next, a fourth embodiment of the present invention will be described.

FIG. 12 is a front view showing a vehicle marker lamp according to the present embodiment without a lens, and FIG.
FIG. 3 is a sectional view taken along line XIII-XIII.

As shown in FIG. 12, also in this embodiment, a plurality of diffuse reflection surface elements 16s constituting the reflection surface 16a of the reflector 16 are formed by dividing the reflection surface 16a into horizontal stripes. The point assigned to each of the plurality of rectangular segments sg formed by further dividing each of the (seven) band-shaped segments SG into vertical stripes is the same as in the first embodiment, but the above-mentioned band-shaped segments are assigned. The plurality of rectangular segments s in the segment SG
g differs from the first embodiment in that g is formed with a gradually changing pitch set so that the width becomes narrower as approaching the left and right ends of the reflection surface 16a.

Further, as shown in FIG. 13, the present embodiment is similar to the first embodiment in that each of the diffuse reflection surface elements 16s is constituted by a cylindrical reflection surface element. Each diffuse reflection surface element 16s of the present embodiment is formed with a single paraboloid of revolution having the optical axis Ax as a central axis as a reference surface, whereas each diffuse reflection surface element 16s of the present embodiment is a so-called diffuse reflection surface element 16s. This embodiment differs from the first embodiment in that a multiple paraboloid is formed as a reference plane.

That is, as shown in detail in FIG. 14, each diffuse reflection surface element 16s of the present embodiment has the same axis line with the position of the filament 12a on the optical axis Ax as a common focal point (in all cases, the optical axis Ax). Ax) is a curved surface (convex cylindrical curved surface) having different curvatures in the left-right direction, based on a plurality of rotating paraboloids having different focal lengths. As shown in the drawing, the focal lengths f1, f2,... As the distance from the optical axis Ax in the left-right direction increases.
It is set to gradually become a large value. Thus, the thickness of the reflector 16 is reduced. In this embodiment, the valve 1
2 is inserted from a slightly oblique direction with respect to the optical axis Ax.

FIG. 15 is a view showing how the reflecting surface 16a is viewed from the front of the lamp when the bulb 12 is turned on in the reflector 16 of this embodiment.

As shown in FIG.
s is a vertical streak-like brilliant portion Br as in the first embodiment.
Although it looks shiny as o, since the rectangular segments sg are formed at gradually changing pitches in each of the strip-shaped segments SG, the reflection surface 16a as a whole is sparse at the center and denser toward the left and right ends. A plurality of shining vertical streak-shaped brilliant portions Bro are formed over a plurality of upper and lower stages in a state of being shifted by approximately a half pitch, and appear to shine in a modified staggered arrangement. Thus, a three-dimensional effect (or a sense of depth) can be given to the observer as well as a glitter effect.

Therefore, the reflector 16 of this embodiment is
Even when observed as a lamp with a lens over it,
Compared with the lamp 10 of the first embodiment or the second embodiment, a novel feeling can be given to the observer. Especially,
The lens 1 of the second embodiment is added to the reflector 16 of the present embodiment.
