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 reflecting surface elements are formed on a reflecting surface of a reflector.

[0002]

2. Description of the Related Art In recent years, so-called step reflectors, in which a plurality of reflecting surface elements are formed on a reflecting surface, are often used in vehicle marker lights.

[0003] Generally, this step reflector is shown in FIG.
As shown in FIG. 3, the reflecting surface 6a is divided into a plurality of strip-shaped reflecting surface elements 6s extending in the form of vertical stripes, and the light from the light source bulb 2 is diffusely reflected in the left and right directions by the respective reflecting surface elements 6s. It is made to let.

In a marker lamp equipped with such a step reflector, it is possible to secure required light distribution performance without the need to form a fish-eye lens step on the lens. The inside of the lamp becomes easier to see, which can enhance the transparency of the lamp.

[0005]

However, since the conventional step reflector 6 of the conventional marker lamp has a structure in which a plurality of reflecting surface elements 6s are simply allocated to the reflecting surface 6a at substantially equal intervals, the step reflector 6 is not used. In any case when the lamp is not lit, a person who observes the lamp from the front cannot be given a sense of depth greater than the actual depth dimension of the step reflector 6.

For this reason, the adoption of the step reflector makes it possible to enhance the transparency of the lamp, but the appearance cannot be improved much.
There is a problem.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a sign lamp provided with a step reflector and having a sufficient depth and a good appearance. It is assumed that.

[0008]

SUMMARY OF THE INVENTION The present invention achieves the above object by using a linear perspective method in allocating a plurality of reflecting surface elements to a reflecting surface of a reflector.

That is, according to a first aspect of the present invention, as described in claim 1, a light source bulb, a reflector having a reflecting surface for reflecting light from the light source bulb forward, and a reflector provided in front of the reflector are provided. The reflecting surface is defined by a pair of boundary lines extending substantially obliquely downward from left and right in the vicinity of the optical axis of the reflector in a front view of the lamp. The lower reflective region is divided into a plurality of strip-shaped reflective surface elements extending in a substantially horizontal stripe shape, and the upper and lower widths of these reflective surface elements are divided into a lower reflective region and an upper reflective region. The lower reflection area is set so as to gradually increase from the upper end to the lower end.

According to a second aspect of the present invention, there is provided a light source bulb, a reflector having a reflecting surface for reflecting light from the light source bulb forward, and a reflector provided in front of the reflector. The reflecting surface is defined by a pair of boundary lines extending substantially obliquely downward from left and right in the vicinity of the optical axis of the reflector in a front view of the lamp. The upper reflection region is divided into a plurality of strip-shaped reflection surface elements extending in a substantially vertical stripe shape, and the left and right widths of these reflection surface elements are divided into a lower reflection region and an upper reflection region. Are set so as to gradually increase from the vicinity of the optical axis to both right and left ends.

The "pair of boundary lines" may extend linearly or in a curved shape as long as they extend substantially obliquely downward from left and right in the vicinity of the optical axis toward the left and right. May be extended, and each of these "boundary lines"
May be actually visible as a continuous line on the reflection surface, or may be invisible as a continuous line.

[0012]

As described above, according to the first aspect of the present invention, in the first aspect of the present invention, the reflecting surface of the reflector is formed in a substantially C-shape from the vicinity of the optical axis of the reflector to a diagonally right and left downward direction in a lamp front view. The lower reflection region is divided into a lower reflection region and an upper reflection region with a pair of extending boundary lines as boundaries, and the lower reflection region is divided into a plurality of band-shaped reflection surface elements extending in a substantially horizontal stripe shape. In addition, since the upper and lower widths of these reflection surface elements are set so as to gradually increase from the upper end to the lower end of the lower reflection area,
The following operational effects can be obtained.

That is, in general, near objects are large, far objects look small, and when a plurality of objects are arranged at equal intervals, near objects are sparsely distant objects are densely arranged. Looks done. Linear perspective is known as a technique for creating perspective using such a visual effect.

Considering the configuration of the first invention of the present application in light of this linear perspective, the lower reflective area on the reflective surface of the reflector is divided into a plurality of strip-like reflective surface elements extending in a substantially horizontal stripe shape. Since the upper and lower widths of these reflecting surface elements are set so as to gradually increase from the upper end to the lower end of the lower reflective area, a relatively dense upper end is more sparse than a relatively sparse lower end. Seen as far away. Also, since the left and right ends of the lower reflection area are separated by the pair of boundary lines extending in a substantially C shape, the upper end where the length of the reflection surface element is relatively short is the lower end where the length is relatively long. Appears to be farther than the head. From the above, the lower reflection area looks like a single road or a floor extending from the near side to the far side, and thus looks much deeper than the actual depth dimension of the lower reflection area.

Therefore, according to the first aspect of the present invention, in the marker lamp provided with the step reflector, a person who observes the reflection surface through the lens can be given a sufficient sense of depth. Appearance can be improved. Such an effect can be obtained in any case of lighting and non-lighting.

In the first aspect of the present invention, it is needless to say that each of the reflecting surface elements may be constituted only by a smooth curved surface (or flat surface) such as a convex surface, a concave surface, and a wavy surface. As described above, the configuration may be made up of an element main body (that is, a portion formed of a smooth curved surface (or plane) such as a convex surface, a concave surface, or a wavy surface) and a step portion. In the latter case, as described in the claim, if the upper and lower widths of the respective element main bodies are set so as to gradually increase from the upper end to the lower end of the lower reflection region, the following operational effects can be obtained. Can be obtained.

That is, in the first invention of the present application, a sufficient sense of depth can be ensured in both the case of lighting and the case of non-lighting. Since it looks remarkably brighter than that of the above, by gradually changing not only the vertical width of each reflecting surface element but also the vertical width of its element body as described above, the sense of depth at the time of lighting is further emphasized. be able to.

In this case, if the upper and lower widths of the step portions are set so as to gradually increase from the upper end to the lower end of the lower reflection region, the non-lighting state is achieved. The sense of depth at the time can be further emphasized.

As in the first invention of the present application, a sufficient depth feeling can be ensured by allocating a plurality of reflecting surface elements to the lower reflecting area by applying the linear perspective method. Similarly, if a plurality of reflective surface elements are allocated to the upper reflective area by applying the linear perspective method, the sense of depth can be further enhanced.

That is, as described in claim 4, at least a region above the boundary line in the upper reflection region is divided into a plurality of strip-shaped reflection surface elements extending in a substantially vertical stripe shape. If the left and right widths of the reflection surface element are set so as to gradually increase from the portion near the optical axis to the left and right end portions, as described above, the lower reflection region is one road or floor extending from the near side to the far side. And so on, the upper neighborhood area of each of the above boundary lines looks like a row of trees or a wall extending from the near side to a far side, so that there is much more depth than the actual depth dimension of the upper neighborhood area. appear.

At this time, each of the reflection surface elements constituting the upper reflection area is also constituted by an element main body and a step portion, and the left and right widths of the respective element main bodies are set from the vicinity of the optical axis to the left and right ends. If it is set so as to gradually widen, the sense of depth at the time of lighting can be further emphasized, and at that time, the left and right width of each step portion gradually increases from the portion near the optical axis to the left and right end portions. If the setting is made wider, the sense of depth at the time of non-lighting can be further emphasized.

The structure of the upper reflection region other than the region near the upper side of each boundary line is not particularly limited, and each reflection surface element allocated to the upper vicinity region is formed to extend upward as it is. Such a configuration may be adopted, or a plurality of strip-shaped reflective surface elements extending so as to bridge the above-described pair of left and right neighboring areas so as to be viewed as a flat or arched ceiling may be used.
In the latter case, it is needless to say that it is preferable to increase the vertical width of each reflecting surface element from the lower end to the upper end of the area so as to gradually increase the depth.

However, in the upper reflection region other than the region above the boundary line, the depth of the lower reflection region or the upper reflection region is higher than that of the boundary line. Since the degree of contribution is not high, a single curved surface or a free curved surface that is not divided and formed into a plurality of reflective surface elements may be used.
In this case, the area can be expected to look like the sky or an open space above the head.

In the first invention of the present application, the "lens"
Although the specific configuration of is not particularly limited, as described in claim 8, a pair of boundary lines formed at positions substantially overlapping with the pair of boundary lines in a lamp front view are defined as boundaries. A lower lens area and an upper lens area, and the lower lens area is divided into a plurality of lens steps extending in a direction intersecting with a direction in which each of the reflection surface elements constituting the lower reflection area extends. If the upper lens region is divided into a plurality of lens steps extending in a direction intersecting with the direction in which the respective reflection surface elements constituting the upper reflection region extend, the required light distribution performance as a lamp can be easily achieved. And it is possible to prevent the lens pattern from interfering with the reflector pattern and hindering the sense of depth created by the reflector. Kill.

In this case, the direction in which each lens step extends in each lens region is not particularly limited as long as it intersects with the direction in which each reflecting surface element constituting each reflection region extends. For example, it may be set in a direction orthogonal to each of the reflection surface elements constituting each of the reflection areas, or may be set in a direction extending substantially radially from a portion near the optical axis. In the case of adopting the latter example, since the linear perspective is applied to the lens, it is more effective in increasing the sense of depth of the lamp.

Instead of the first invention of this application, as in the second invention of this application, the upper reflection area on the reflection surface of the reflector is divided into a plurality of band-like reflection surface elements extending in a substantially vertical stripe shape, and each of these elements is formed. It is also possible to set the lateral width of the reflective surface element so as to gradually increase from the vicinity of the optical axis to the left and right ends. In this case, the relatively dense portion near the optical axis appears to be farther than the relatively sparse left and right ends. Further, since the lower end of the upper reflection area is partitioned by the pair of boundary lines extending in a substantially C shape, the portion near the optical axis where the length of the reflection surface element is relatively short is relatively long. It appears to be farther than the left and right ends. From the above, the upper reflection area looks like a row of trees or a wall extending from the near side to the far side, and thus appears to be much deeper than the actual depth dimension of the upper reflection area.

Therefore, according to the second aspect of the present invention, in the marker lamp provided with the step reflector, a person who observes the reflection surface through the lens can be given a sufficient sense of depth. Appearance can be improved. Such an effect can be obtained in any case of lighting and non-lighting.

In the second aspect of the present invention, it is a matter of course that each of the reflecting surface elements may be constituted only by a smooth curved surface (or flat surface) such as a convex surface, a concave surface, or a wavy surface. As described in (1), the device may be configured to include an element main body (that is, a portion formed of a smooth curved surface (or plane) such as a convex surface, a concave surface, or a wavy surface) and a step portion. In the latter case, as described in the claim, if the left and right widths of the respective element main bodies are set so as to gradually increase from the portion near the optical axis of the lower reflection region to the left and right end portions, the following is possible. Such an operation and effect can be obtained.

That is, in the second aspect of the present invention, a sufficient sense of depth can be ensured in both the case of lighting and the case of non-lighting. Since it looks remarkably brighter than that of the above, the left-right width of each of the reflecting surface elements as well as the left-right width of the element body is gradually changed as described above to further emphasize the sense of depth at the time of lighting. be able to.

In this case, furthermore, as described in claim 7, the left and right widths of each of the step portions may be set so as to gradually increase from the portion near the optical axis of the lower reflection region to both right and left ends. Also, the sense of depth at the time of non-lighting can be further emphasized.

In each of the first and second aspects of the present invention, each of the "steps" may be a step formed so that the side away from the optical axis is retracted, or a step opposite thereto. However, in the former case, the actual depth dimension of the upper reflection area is short, so that the present invention is more effective in securing the sense of depth.

2a and an outer step 16s2b.

Each of the element body portions 16s1a is formed to have a concave cross section in a vertical cross section, so that light from the light source bulb 12 is diffused and reflected in the vertical direction toward the front. . Then, the step 16
s1b is formed in a linear shape whose vertical cross-sectional shape retreats downward. In addition, each element body 16s
2a has a horizontal cross-sectional shape formed into a concave curve, and thereby diffuses and reflects light from the light source bulb 12 in the left-right direction toward the front. And
The step portion 16s2b is formed in a linear shape whose horizontal cross-sectional shape recedes outward.

The vertical width D1 of each element body 16s1a

In addition, the left and right widths D2b of the step portions 16s2b are all the same as the optical axis A.
It is set so as to gradually increase from the vertical line L passing through x to both right and left ends of the upper reflection area 16a2.

Each of the reflection surface elements 16s2 constituting the upper reflection region 16a2, its element body portion 16s2a and the step portion 16s2b are provided on each of the boundary lines BL with each of the reflection surface elements 16s1 constituting the lower reflection region 16a1 and The element body 16s1a and the step 16s1b are formed so as to have the same pitch.

As shown in FIG. 1, the lens 18 has an inner surface 18a separated by a pair of boundary lines BL 'formed at a position overlapping with the pair of boundary lines BL in a front view of the lamp. , Lower lens area 18a1 and upper lens area 1
8a2. Each of these lens areas 18
a1 and 18a2 are each a plurality of lens steps 18
It is divided into s1 and 18s2.

The lower lens region 18a1 is divided into a plurality of wedge-shaped lens steps 18s1 extending radially around the optical axis Ax. The upper lens region 18a2 is divided into a plurality of strip-shaped lens steps 18s2 whose vertical width gradually increases from the vertical line L to the left and right ends of the upper lens region 18a2.

At this time, each lens step 1 formed on the right side of the vertical line L in the upper reflection area 16a2
8s2 is formed as a part of an elongated wedge-shaped segment radially extending to the right with the obliquely upper left position of the optical axis Ax as a vanishing point, while being formed on the left side of the vertical line L in the upper reflection region 16a2. Each of the lens steps 18s2 is formed as a part of an elongated wedge-shaped segment that extends radially to the left with the obliquely upper right position of the optical axis Ax as a vanishing point.

Each of the lens steps 18s1 constituting the lower lens region 18a1 has a horizontal cross-sectional shape formed into a convex curve, whereby the light reflected from the reflection surface 16a (mainly from the lower reflection region 16a1). (Reflected light) is diffused and transmitted in the left-right direction toward the front. Each of the lens steps 18s2 constituting the upper lens region 18a2 has a vertical cross-sectional shape formed into a convex curve, thereby allowing the reflection surface 16a2 to be formed.
The light reflected from a (mainly the light reflected from the upper reflection area 16a2) is diffused and transmitted in the vertical direction toward the front.

Then, by the combination of the diffuse reflection by the reflector 16 and the diffuse transmission by the lens 18,
The diffuse irradiation light in the vertical and horizontal directions required for the light distribution performance of the lamp is secured.

As described above in detail, in the present embodiment, the pair of reflecting surfaces 16a of the reflector 16 extend obliquely downward and to the left and right from the optical axis Ax of the reflector 16 when viewed from the front of the lamp. A lower reflection region 16a1 and an upper reflection region 16a2 are divided by the boundary line BL, and the lower reflection region 16a1 is divided into a plurality of strip-shaped reflection surface elements 16s1 extending in a horizontal stripe shape. Since the upper and lower widths D1 of these reflecting surface elements 16s1 are set so as to gradually increase from the upper end to the lower end of the lower reflecting area 16a1, the reflecting surface elements 16s1 are relatively densely arranged. The upper end appears to be farther than the lower end where it is relatively sparsely arranged, and the left and right ends of the lower reflective area 16a1 are Because it is divided by the boundary line BL, and is relatively short upper part length of the reflecting surface elements 16s1 appears as being farther than a relatively long bottom section.

As described above, the lower reflection area 16a1
According to the principle of linear perspective, it looks like a single road or floor extending from the near side to the far side, so that it looks much deeper than the actual depth dimension of the lower reflection area 16a1.

Therefore, according to the present embodiment, in the marker lamp provided with the step reflector, a person who observes the reflection surface through the lens can be given a sufficient sense of depth. Appearance can be improved. Such an effect can be obtained in any case of lighting and non-lighting.

Further, in the present embodiment, a plurality of reflection surface elements 16s2 are allocated to the upper reflection region 16a2 by applying the linear perspective method in the same manner.
The sense of depth can be further enhanced.

That is, the upper reflection area 16a2 is
It is divided into a plurality of strip-shaped reflective surface elements 16s2 extending in the form of vertical stripes, and the left-right width D2 of each of these reflective surface elements 16s2 is determined from the vertical line L passing through the optical axis Ax to the left and right ends of the upper reflective area 16a2. The upper reflection area 16a2 is set so as to gradually increase toward.
It looks like a row of trees or a wall extending from the near side to the far side. For this reason, in combination with the fact that the lower reflection area 16a1 looks like a single road or a floor extending from the near side to the far side, the reflection surface 16a is much deeper than its actual depth dimension. Will look like this.

In this embodiment, each of the reflection surface elements 16s1 and 16s2 is composed of an element body 16s1a and 16s1a, respectively.
6s2a and the step portions 16s1b and 16s2b, but each of the element body portions 16s1 which looks brighter when turned on than the step portions 16s1b and 16s2b.
a, 16s2a, the width D1a, D2a is the optical axis Ax
(Or the vertical line L), the width is set to gradually increase as the distance increases, so that the width of the brightly glowing portion at the time of lighting appears to change gradually, whereby the sense of depth at the time of lighting can be further emphasized. .

In the present embodiment, the optical axis Ax is also provided for each of the steps 16s1b and 16s2b.
Since the widths D1b and D2b are set so as to gradually increase as the distance from the vertical line L (or the vertical line L) increases, the sense of depth at the time of non-lighting can be further emphasized. In addition, each of the steps 16s1b, 16s2
Since b is formed so that the side away from the optical axis Ax (or the vertical line L) is receded, the actual depth dimension of the reflection surface 16a can be set short, thereby reducing the thickness of the lamp. While increasing the sense of depth.

Furthermore, in the present embodiment, a pair of boundary lines B formed at positions where the inner surface 18a of the lens 18 overlaps the pair of boundary lines BL when viewed from the front of the lamp.
The lower lens area 18a1 and the upper lens area 18a2 are divided by L 'as a boundary, and the respective lens areas 18a1 and 18a2 are located behind the respective reflection areas 16a.
1 and 16a2, each reflecting surface element 16s1, 16s
Since it is divided into a plurality of lens steps 18s1 and 18s2 extending in a direction intersecting with the direction in which 2 extends,
It is possible to easily secure the required light distribution performance as a lamp, and to prevent the lens pattern from interfering with the reflector pattern and obstructing the sense of depth created by the reflector 16 beforehand. it can.

In the present embodiment, the lens steps 18s1 and 18s2 are formed so as to extend substantially radially from the optical axis Ax (or the vertical line L). Perspective is applied, which can further enhance the sense of depth of the lamp.

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

FIG. 5 is a front view showing a vehicle marker light according to this embodiment.

As shown, the configuration of the lens 18 in this embodiment is different from that of the first embodiment.

That is, the point that the inner surface 18a of the lens 18 of this embodiment is divided into a lower lens region 18a1 and an upper lens region 18a2 with a pair of boundary lines BL 'as a boundary is different from the first embodiment. Similarly, the lower lens region 18a1 is divided into a plurality of band-shaped lens steps 18s1 extending in the form of vertical stripes at equal intervals, and the upper lens region 18a2 is formed in the form of a plurality of band-like lenses extending in the horizontal stripes at equal intervals. It differs from the first embodiment in that it is divided and formed in step 18s2.

Each lens step 18s1, 18s constituting the lens 18a2
2 is formed so as to be orthogonal to the respective reflection surface elements 16s1 and 16s2 constituting the respective reflection regions 16a1 and 16a2 at the rear thereof, the required light distribution performance as a lamp can be more easily ensured. Also in this case, it is possible to prevent the lens pattern from interfering with the reflector pattern and obstructing the sense of depth created by the reflector 16 beforehand.

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

As shown, in the present embodiment, the upper reflection area 16 on the reflection surface 16a of the reflector 16 is provided.
The configuration of a2 is partially different from that of the first embodiment.

That is, in the present embodiment, a portion above the optical axis Ax in the upper reflection area 16a2 of the reflection surface 16a is constituted by a single curved surface portion 16a2a. The single curved surface portion 16a2a has a contour shape obtained by inverting a short isosceles triangle having a vertex on a vertical line L passing through the optical axis Ax, and the surface shape is the optical axis Ax
It is composed of a paraboloid of revolution whose focus is on the position of the upper filament 12a.

As described above, a part of the upper reflection region 16a2 is constituted by the single curved surface portion 16a2a, and the upper reflection region 16a2 is formed by a pair of contours extending obliquely upward in the left-right direction from the vertical line L. By dividing by the line (that is, the oblique side of the isosceles triangle) BL2, the single curved surface portion 16a2a becomes an empty or overhead open space extending above a row of trees or a wall surface extending from the near side to the far side according to the principle of linear perspective. Looks like etc. Thereby, the sense of depth of the reflection surface 16a can be further enhanced.

When the upper reflection region 16a2 is configured as in the present embodiment, the inner surface 18a
If the area in front of the single curved surface portion 16a2a is constituted by a fish-eye lens step, the required light distribution performance as a lamp can be reliably ensured, but the area of the single curved surface portion 16a2a Since it is extremely small, the required light distribution performance can be secured in some cases even with the lens step 18s2. In this case, if it is difficult to ensure the required light distribution performance, the single curved surface portion 16a2a may be formed of a single curved surface different from the paraboloid of revolution, or the single curved surface portion 16a2a may be formed of a wavy curved surface. , Etc., it is possible to secure required light distribution performance.

1 and 16s2 are element body portions 16s1a and 16s2a, respectively.
And the step portions 16s1b and 16s2b, the reflection surface elements 16s1 and 16s2, the element body portions 16s1a and 16s2a, and the step portions 16s1b.

And extend in an inverted C-shape at an equal angle to the left and right so as to be located on the extension of the.

The point that each of the reflection areas 16a1 and 16a2 is divided into a plurality of strip-shaped reflection surface elements 16s1 and 16s2,
The point that the width of 1, 16s2 is set so as to gradually increase as the distance from the optical axis Ax increases is the first.
Same as the embodiment, but each of the reflection surface elements 16s1,
16s2 is different from the first embodiment in that it has a concave cross-sectional shape over its entire width.

The reflection surface elements 16s1 forming the lower reflection region 16a1 and the reflection surface elements 16s2 forming the upper reflection region 16a2 have the same pitch and the same cross-sectional shape on each of the boundary lines BL. The reflection surface elements 16s2 forming the side portions 16a2A and the reflection surface elements 16s2 forming the upper portion 16a2B are defined by the contour line BL2.
In the above, they are formed so as to have the same pitch and the same cross-sectional shape.

For this reason, in the present embodiment, each of the boundary lines BL and the outline lines BL2 is formed by the reflection surface 16a.
Although it does not appear as a continuous line on the top (for this reason, it is shown by a two-dot chain line in FIG. 10),
It can be recognized as a virtual line connecting the boundary corner points of 6s1 and the above-mentioned respective reflection surface elements 16s2.

As in the present embodiment, each of the reflecting surface elements 1
Even when 6s1 and 16s2 are configured to have no stepped portion, and without forming the boundary lines BL (and the contour lines BL2) as actual continuous lines, the lamps can be used according to the principle of linear perspective. The sense of depth can be increased.

In each of the above embodiments, each of the reflection surface elements 16s1 forming the lower reflection region 16a1 and each reflection surface element 16s2 forming the upper reflection region 16a2 have the same pitch on each of the boundary lines BL. (In some cases, the reflection surface elements 16s2 forming the side portions 16a2A of the upper reflection region 16a2 and the reflection surface elements 16s2 forming the upper portion 16a2B are also formed as described above.) Although they are formed to have the same pitch on the contour line BL2),
It is not always necessary to form them at the same pitch, and even when the pitch is shifted, the sense of depth of the lamp can be increased by the principle of linear perspective.
