Description

The present invention relates to a vehicle lamp, and more particularly to a vehicle lamp that can be visually recognized as if the first light emitting region and the second light emitting region are integrally (connected) to emit light regardless of the viewpoint position.

5 (a) is a cross-sectional view of the vehicle lamp described in Patent Document 1, and FIG. 5 (b) is a cross-sectional view of A1-A1 of FIG. 5 (a).

As shown in FIG. 5A, the rear combination lamps 100 provided on the left and right sides of the rear end of the vehicle and the lid lamps 110 provided on the movable parts such as the trunk lid of the vehicle are horizontally sandwiched by a gap 120. When arranged adjacent to each other (with the trunk lid closed), the first light emitting region a1 formed by lighting the rear combination lamp 100 and the second light emitting region formed by lighting the lid lamp 110. The rear of the gap 120 so that the first light emitting region a1 and the second light emitting region a2 can be visually recognized as being integrally emitting light without forming a dark part (dark part corresponding to the gap 120) between the a2 and the a2. It has been proposed to arrange the light emitting unit 130 in (see, for example, Patent Document 1). The light emitting unit 130 emits light when the light from the light source 140 that has entered the light guide unit 150 is internally reflected by a lens cut provided on the back surface of the light guide unit 150 and emitted from the surface of the light guide unit 150. ..

FIG. 6A is a schematic diagram of the positional relationship between the first light emitting region a1, the second light emitting region a2, and the third light emitting region a3 (light emitting unit 130) when visually recognized from the position p1 in FIG. 5 (b). be. FIG. 6B is a schematic diagram of the positional relationship between the first light emitting region a1, the second light emitting region a2, and the third light emitting region a3 (light emitting unit 130) when visually recognized from the position p2 in FIG. 5 (b). be.

In Patent Document 1, when visually recognized from the position p1 (see FIG. 5 (b)), as shown in FIG. 6 (a), the third light emitting region a3 (light emitting unit 130) does not protrude from the gap 120 (does not shift). Therefore, it is visually recognized that the first light emitting region a1 and the second light emitting region a2 are integrally (connected) to emit light.

Japanese Unexamined Patent Publication No. 2016-134326

However, as a result of examination by the present inventor, in Patent Document 1, since the light emitting portion 130 is arranged at a position shifted to the rear of the gap 120 (see FIG. 5 (a) and FIG. 5 (b)), the position. When visually recognized from the position p2 above p1 (see FIG. 5 (b)), as shown in FIG. 6 (b), the third light emitting region a3 (light emitting unit 130) protrudes (shifts) from the gap 120. There is a problem that the first light emitting region a1 and the second light emitting region a2 are not visually recognized as if they are integrally (connected) to emit light.

The present invention has been made to solve such a problem, and it is visually recognized as if the first light emitting region and the second light emitting region are integrally (connected) to emit light regardless of the viewpoint position. It is an object of the present invention to provide a lighting fixture for a vehicle which can be made to.

The vehicle lamp according to the present invention forms a third light emitting region that is visually recognized through the gap between the first light emitting region and the second light emitting region that are arranged adjacent to each other with a gap in the horizontal direction. A light source having a light emitting surface and a reflecting surface on which the light emitting surface is reflected are provided, and the light source is arranged behind the gap with the light emitting surface facing downward. The reflective surface is formed between an upper end portion arranged behind the light source, a lower end portion arranged between the upper end portion and the gap and below the gap, and between the upper end portion and the lower end portion. An image of the light emitting surface reflected on the curved reflective surface, which is arranged and includes a curved reflecting surface concave toward the gap and is visible through the gap, is seen from the gap regardless of the viewpoint position. The curved reflective surface is configured so as not to protrude.

With such a configuration, it is possible to provide a vehicle lamp that can be visually recognized as if the first light emitting region and the second light emitting region are integrally (connected) to emit light regardless of the viewpoint position.

This is because the third light emitting region (the image of the light emitting surface of the light source that follows the viewpoint position and is reflected on the curved reflection surface) that is visually recognized through the gap does not protrude (do not shift) from the gap regardless of the viewpoint position. This is due to the fact that the curved reflective surface is configured as described above.

In the vehicle lighting equipment, the first light emitting region may be arranged at the rear end portion of the vehicle, and the second light emitting region may be arranged at a movable portion movable with respect to the first light emitting region.

Further, in the vehicle lamp, a gap lens portion is arranged between the gap and the reflection surface to emit light in a region corresponding to the image when the image reflected on the curved reflection surface is transmitted. You may be.

Further, in the vehicle lamp, the lens portion for the gap may extend downward from the gap in front view.

Further, in the vehicle lamp, the lens portion for the gap may extend above and below the gap in front view.

Further, in the vehicle lighting equipment, the curved surface reflecting surface is a parabolic-shaped reflecting surface whose focal point is located on the light emitting surface of the light source, and is reflected on the curved surface reflecting surface which is visually recognized through the gap. The surface shape and inclination of the curved reflective surface may be adjusted so that the image of the light emitting surface does not protrude from the gap regardless of the viewpoint position.

Hereinafter, a vehicle lamp 30 according to an embodiment of the present invention will be described with reference to the accompanying drawings. The corresponding components in each figure are designated by the same reference numerals, and duplicate explanations are omitted.

FIG. 1 is a front view of a rear end portion of a vehicle V on which a vehicle lamp 30 is mounted (vehicle lamp 30 is omitted in FIG. 1). FIG. 2A is a partially enlarged view seen from the direction of arrow A in FIG. 1 (the base plate 34 in FIG. 2A is omitted). FIG. 2B is a cross-sectional view taken along the line AA of FIG. 2A.

As shown in FIG. 1, rear combination lamps 10 and lid lamps 20 are arranged on the left and right sides of the rear end portion of the vehicle V such as an automobile, respectively. The lid lamp 20 is arranged on a movable portion 40 (see FIG. 1) such as a trunk lid provided at the rear end of the vehicle V. Hereinafter, for convenience of explanation, the XYZ axes are defined as shown in FIG. 1 and the like. The X-axis extends in the front-rear direction of the vehicle. The Y-axis extends in the vehicle width direction. The Z-axis extends in the vertical direction.

The rear combination lamp 10 and the lid lamp 20 are arranged adjacent to each other with the movable portion 40 closed and a gap S (see FIGS. 1 and 2A) in the Y-axis direction. At that time, the rear combination lamp 10 and the lid lamp 20 are arranged so that their end portions face each other. The heights H (see FIG. 1) of the rear combination lamps 10 and the lid lamps 20 facing each other in the Z-axis direction are the same. The width W2 (see FIG. 2A) of the gap S in the Y-axis direction is, for example, about 5 mm.

As shown in FIG. 2, a vehicle lighting tool 30 is arranged behind the gap S between the rear combination lamp 10 and the lid lamp 20. Since the rear combination lamps 10, the lid lamps 20, and the vehicle lighting fixtures 30 mounted on both the left and right sides have a symmetrical configuration, the following is represented below on the right side of the rear end of the vehicle (on the right side when facing the front of the vehicle). The rear combination lamp 10, the lid lamp 20, and the vehicle lighting equipment 30 to be mounted will be described.

The rear combination lamp 10, the lid lamp 20, and the vehicle lamp 30 are turned on at the same time, and function as, for example, a tail lamp and a stop lamp. The optical system constituting the rear combination lamp 10 and the lid lamp 20 may have any configuration as long as the desired lamp function (for example, tail lamp, stop lamp) can be realized. For example, the optical system constituting the rear combination lamp 10 and the lid lamp 20 may be an optical system in which a light source such as an LED and a reflecting surface are combined, or a light source such as an LED and a light guide body (for example, a light guide plate). It may be an optical system in combination with a light guide rod), or it may be another optical system.

In FIG. 1, the hatched region indicated by reference numeral A1 represents a first light emitting region (for example, an outer lens constituting the rear combination lamp 10) formed by lighting the rear combination lamp 10. Hereinafter, it will be referred to as a first light emitting region A1. In FIG. 2, the hatched region indicated by reference numeral A2 represents a second light emitting region (for example, an outer lens constituting the lid lamp 20) formed by lighting the lid lamp 20. Hereinafter, it will be referred to as a second light emitting region A2.

Next, the vehicle lamp 30 will be described.

As shown in FIGS. 2A and 2B, the vehicle lamp 30 includes a light source 31, a light source 32 on which the light source 31 (light emitting surface 31a) is reflected, and a light source 31 reflected by the light source 32. It is provided with a gap lens portion 33 through which light from the light source is transmitted. Although not shown, the vehicle lamp 30 is arranged in a lighting chamber composed of an outer lens and a housing, and is attached to the housing or the like.

The light source 31 is a semiconductor light emitting element such as an LED. The light source 31 has a light emitting surface 31a. The light emitting surface 31a is, for example, a rectangular light emitting surface of 1 mm square. The light source 31 is attached to the base plate 34 behind the gap S and above the gap S with the light emitting surface 31a facing downward (see FIG. 2B). At that time, as shown in FIG. 2A, the light source 31 has a pair of sides 31b and 31c facing each other of the light emitting surface 31a that coincide with each other in the X-axis direction, and another pair of the light emitting surfaces 31a facing each other. Sides 31d and 31e are arranged so as to coincide with the Y-axis direction). The base plate 34 is, for example, a plate-shaped portion parallel to the XY plane, and is integrally formed with the reflecting surface 32. The base plate 34 may be configured in a state of being physically separated from the reflecting surface 32.

The reflective surface 32 includes an upper end portion 32a arranged behind the light source 31, a lower end portion 32b arranged between the upper end portion 32a and the gap S and below the gap S, and an upper end portion 32a and a lower end portion 32b. A curved reflective surface 32c, which is arranged between them and whose cross section by the XZ plane is concave toward the gap S, is included. The width W1 of the reflective surface 32 in the Y-axis direction (see FIG. 2A) generally coincides with the width W2 of the gap S in the Y-axis direction (see FIG. 2A). The reflecting surface 32 (curved surface reflecting surface 32c) is not a perfect paraboloid but a paraboloid-like reflecting surface. This point will be described later.

The curved surface reflecting surface 32c is visually recognized through the gap S (and the lens portion 33 for the gap), and is an image of the light emitting surface 31a reflected on the curved surface reflecting surface 32c (for example, in FIG. 2B, reference numerals I1 to I3). The images I1 to I3 or these are collectively referred to as an image I) are configured so as not to protrude (do not shift) from the gap S regardless of the viewpoint position. Note that "not to protrude from the gap S" does not mean that the image I does not protrude from the gap S at all, but the first light emitting region A1 and the second light emitting region A2 are integrally as described later. If it can be visually recognized as if it is emitting light (connected), it means that the image I may slightly protrude from the gap S in the vertical and horizontal directions.

Specifically, the curved surface reflecting surface 32c is an image I (for example) of the light emitting surface 31a of the light source 31 reflected on the curved surface reflecting surface 32c for each viewpoint position (for example, see the viewpoint positions P1 to P3 in FIG. 2B). For example, the upper end of the images I1 to I3) and the upper end of the gap S coincide with each other (see the straight lines L1 to L3 in FIG. 2B), and the image I of the light emitting surface 31a of the light source 31 reflected on the curved reflective surface 32c. (For example, the lower end of the images I1 to I3) and the lower end of the gap S coincide with each other (see the straight lines L4 to L6 in FIG. 2B). At that time, the viewpoint position is from the viewpoint position P1 (the position in the front direction of the vehicle lamp 30 (gap S); hereinafter also referred to as the front position P1) to the viewpoint position P2 (the position above the front position P1; hereinafter, the upper position P2). The apparent width of the image I of the light emitting surface 31a reflected on the curved surface reflecting surface 32c, which is visually recognized through the gap S (and the lens portion 33 for the gap), becomes narrower toward the direction (also referred to as). The width LB of the image I2 <the width LA of the image I1; see FIG. 2B), and the surface shape and inclination of the curved reflective surface 32c are adjusted. Similarly, as the viewpoint position moves from the front position P1 to the viewpoint position P3 (a position below the front position P1; hereinafter also referred to as a lower position P3), it is visually recognized through the gap S (and the gap lens portion 33). The curved reflective surface is such that the apparent width of the image I of the light emitting surface 31a reflected on the curved reflective surface 32c is narrowed (for example, the width LC of the image I3 <the width LA of the image I1; see FIG. 2B). The surface shape and inclination of 32c are adjusted.

A specific example of the curved surface reflecting surface 32c will be described.

The curved surface reflecting surface 32c is a paraboloid-like reflecting surface whose surface shape and inclination of the reference paraboloid are adjusted. As shown in FIGS. 2A and 2B, the focal point F of the reference paraboloid is located at the center of the light emitting surface 31a. Although not shown, the axis of the reference paraboloid passes through the focal point F and extends in the X-axis direction.

The surface shape and inclination of the curved surface reflecting surface 32c are adjusted as follows with respect to the reference paraboloid. Hereinafter, reference numeral 32c _I1 in FIG. 2B represents a reflection region in which the image I1 is reflected in the curved surface reflection surface 32c. Hereinafter, it is referred to as a first reflection region 32c _I1 . Similarly, reference numeral 32c _I2 in FIG. 2B represents a reflection region in which the image I2 is reflected in the curved reflection surface 32c. Hereinafter, it is referred to as a second reflection region 32c _I2 . Similarly, reference numeral 32c _I3 in FIG. 2B represents a reflection region in which the image I3 is reflected in the curved reflection surface 32c. Hereinafter, it is referred to as a third reflection region 32c _I3 .

The first reflection region 32c _I1 on which the image I1 is reflected is a reference paraboloid. That is, the focal point of the first reflection region 32c _I1 is the same as the focal point F of the reference paraboloid and is located at the center of the light emitting surface 31a. Further, the axis AX _I1 (see FIG. 2B) of the first reflection region 32c _I1 is the same as the axis of the reference paraboloid, passes through the focal point F, and extends in the X-axis direction.

The light Ray1 (parallel light) from the light source 31 (light emitting surface 31a) reflected by the first reflection region 32c _I1 having the above configuration passes through the gap S. That is, the light Ray1 reflected at the upper end of the first reflection region 32c _I1 passes through the upper end of the gap S (see the straight line L1 in FIG. 2B), and the light reflected at the lower end of the first reflection region 32c _I1 . The light 1 passes through the lower end of the gap S (see the straight line L4 in FIG. 2B), and the light reflected between the upper end and the lower end of the first reflection region 32c _I1 is the upper end and the lower end of the gap S. Pass between and.

On the other hand, the second reflection region 32c _I2 on which the image I2 is reflected is a paraboloidal surface in which the reference paraboloidal surface is tilted at an angle θ1 (see FIG. 2B). That is, the focal point of the second reflection region 32c _I2 is the same as the focal point F of the reference paraboloid and is located at the center of the light emitting surface 31a. Further, the axis AX _I2 (see FIG. 2B) of the second reflection region 32c _I2 passes through the focal point F and extends diagonally upward (angle θ1 direction) with respect to the X axis. Further, the surface shape of the second reflection region 32c _I2 is such that the reflected light reflected by the second reflection region 32c _I2 is condensed and the width LB of the image I2 is narrower than the width LA of the image I1 (straight line L3). Adjust so that the upper end of the second reflection region 32c _I2 (image I2) and the upper end of the gap S are located above, and the lower end of the second reflection region 32c _I2 and the lower end of the gap S are located on the straight line L6). Has been done. As a result, the surface shape of the second reflection region 32c _I2 becomes a shape close to the elliptical reflection surface.

The light Ray2 (parallel light) from the light source 31 (light emitting surface 31a) reflected by the second reflection region 32c _I2 having the above configuration passes through the gap S. That is, the light Ray2 reflected at the upper end of the second reflection region 32c _I2 passes through the upper end of the gap S (see the straight line L3 in FIG. 2B), and the light reflected at the lower end of the second reflection region 32c _I2 . The light 2 passes through the lower end of the gap S (see the straight line L6 in FIG. 2B), and the light reflected between the upper end and the lower end of the second reflection region 32c _I2 is the upper end and the lower end of the gap S. Pass between and.

Further, the third reflection region 32c _I3 in which the image I3 is reflected is a paraboloidal surface in which the reference paraboloidal surface is tilted at an angle θ2 (see FIG. 2B). That is, the focal point of the third reflection region 32c _I3 is the same as the focal point F of the reference paraboloid and is located at the center of the light emitting surface 31a. Further, the axis AX _I3 (see FIG. 2B) of the third reflection region 32c _I3 passes through the focal point F and extends diagonally downward (angle θ2 direction) with respect to the X axis. Further, the surface shape of the third reflection region 32c _I3 is such that the reflected light reflected by the third reflection region 32c _I3 is condensed and the width LC of the image I3 is narrower than the width LA of the image I1 (straight line L2). The upper end of the third reflection region 32c _I3 (image I3) and the upper end of the gap S are located above, and the lower end of the reflection region 32c _I3 and the lower end of the gap S are located on the straight line L5). There is. As a result, the surface shape of the third reflection region 32c _I3 becomes a shape close to the elliptical reflection surface.

The light Ray3 (parallel light) from the light source 31 (light emitting surface 31a) reflected by the third reflection region 32c _I3 having the above configuration passes through the gap S. That is, the light Ray3 reflected at the upper end of the third reflection region 32c _I3 passes through the upper end of the gap S (see the straight line L2 in FIG. 2B), and the light reflected at the lower end of the third reflection region 32c _I2 . The light 3 passes through the lower end of the gap S (see the straight line L5 in FIG. 2B), and the light reflected between the upper end and the lower end of the third reflection region 32c _I3 is the upper end and the lower end of the gap S. Pass between and.

The surface shape and inclination of the curved reflecting surface 32c between the first reflection region 32c _I1 on which the image I1 is reflected and the second reflection region 32c _I2 on which the image I2 is reflected are also adjusted in the same manner as in the second reflection region 32c ₂ . Has been done. As a result, the slope of the curved reflective surface 32c gradually changes from the first reflection region 32c _I1 where the image I1 is reflected toward the second reflection region 32c _I2 where the image I2 is reflected (the angle θ1 gradually increases). ing). Further, the surface shape and inclination of the curved reflecting surface 32c between the first reflection region 32c _I1 on which the image I1 is reflected and the third reflection region 32c _I3 on which the image I3 is reflected are also the same as those of the third reflection region 32c _I3 . , Have been adjusted. As a result, the slope of the curved reflective surface 32c gradually changes from the first reflection region 32c _I1 where the image I1 is reflected toward the third reflection region 32c _I3 where the image I3 is reflected (the angle θ2 gradually increases). ing).

The image I1 represents an image of the light emitting surface 31a reflected on the curved surface reflecting surface 32c, which is visually recognized from the viewpoint position P1 through the gap S (and the gap lens portion 33). Similarly, the image I2 represents an image of the light emitting surface 31a reflected on the curved surface reflecting surface 32c, which is visually recognized from the viewpoint position P2 through the gap S (and the gap lens portion 33). The image I3 represents an image of the light emitting surface 31a reflected on the curved surface reflecting surface 32c, which is visually recognized from the viewpoint position P3 through the gap S (and the gap lens portion 33). Although not shown, curved surface reflection is also performed from any viewpoint position between the viewpoint position P1 and the viewpoint position P2 and any viewpoint position between the viewpoint position P1 and the viewpoint position P3 according to the viewpoint position. An image of the light emitting surface 31a (similar to the images I1 to I3) reflected on the surface 32c is visually recognized.

As described above, the reflecting surface 32 (curved surface reflecting surface 32c) is configured so that the image I of the light emitting surface 31a reflected on the curved surface reflecting surface 32c following the viewpoint position can be visually recognized.

Since the curved surface reflecting surface 32c adjusted as described above has a complicated curved surface shape (for example, a curved surface shape in which the cross section of the XZ plane includes a plurality of curves), the curved surface reflecting surface 32c (surface shape) is a specific numerical value. It is difficult to express by such as.

However, for example, the surface shape and inclination of the curved reflective surface 32c are adjusted for each viewpoint position using predetermined simulation software, and each time the adjustment is made, the light emitting surface 31a of the light source 31 reflected on the curved reflective surface 32c. By confirming the relationship between the image I and the gap S (whether or not it protrudes, etc.), it is reflected on the curved surface reflecting surface 32c which is visually recognized through the gap S (and the gap lens portion 33) as described above. It is possible to find the curved reflecting surface 32c in which the image I of the light emitting surface 31a does not protrude (do not shift) from the gap S regardless of the viewpoint position.

As shown in FIGS. 2A and 2B, a gap lens portion 33 is arranged between the gap S and the reflecting surface 32.

The gap lens portion 33 is, for example, a flat lens portion. At least one of the front surface and the back surface of the gap lens portion 33 is textured (textured surface) in order to diffuse the light from the light source 31 reflected by the reflecting surface 32 transmitted through the gap lens portion 33. ing. In addition, instead of the grain processing (textured surface), a plurality of fine irregularities (lens cut, etc.) may be used. The width W3 of the gap lens portion 33 in the Y-axis direction (see FIG. 2A) substantially coincides with the width W2 of the gap S in the Y-axis direction.

The gap lens portion 33 extends downward from the lower end of the gap S and upwards from the upper end of the gap S in the Z-axis direction (see FIG. 2B).

When the image I reflected on the curved surface reflecting surface 32c passes through the gap lens portion 33 (textured surface), the region corresponding to the image I in the gap lens portion 33 (textured surface) emits light.

For example, when the viewpoint position is the front position P1, the image I1 reflected on the curved surface reflecting surface 32c is the image I1 of the gap lens portion 33 (textured surface) when passing through the gap lens portion 33 (textured surface). The corresponding region, that is, the region between the straight line L1 and the straight line L4 (see FIG. 2B) and the width W3 (see FIG. 2A) (hereinafter referred to as the third light emitting region A3 _I1 ) is made to emit light. ..

FIG. 3A is a schematic diagram of the positional relationship between the first light emitting region A1, the second light emitting region A2, and the third light emitting region A3 _I1 when the viewpoint position is the front position P1.

When the viewpoint position is the front position P1, as shown in FIG. 3A, the third light emitting region A3 _I1 is located between the rear combination lamp 10 (first light emitting region A1) and the lid lamp 20 (second light emitting region A2). It is arranged in the gap S (without protruding from the gap S). Further, when the image I1 reflected on the curved surface reflecting surface 32c is transmitted through the gap lens portion 33 (textured surface), it is diffused on the textured surface and the amount of light is reduced, so that the light emitting region A3 of the gap lens portion 33 (textured surface) _I1 is adjusted to have the same texture as the first and second light emitting regions A1 and A2.

As described above, when the viewpoint position is the front position P1, the third light emitting region A3 _I1 of the gap lens portion 33 (textured surface) adjusted to have the same texture as the first and second light emitting regions A1 and A2 is a rear combination. It is arranged in the gap S between the lamp 10 (first light emitting region A1) and the lid lamp 20 (second light emitting region A2) (without protruding from the gap S) (see FIG. 3A). As a result, when the viewpoint position is the front position P1, it is visually recognized that the first light emitting region A1 and the second light emitting region A2 are integrally (connected) to emit light.

Similarly, when the viewpoint position is the upper position P2, the image I2 reflected on the curved surface reflecting surface 32c is the image I2 of the gap lens portion 33 (textured surface) when passing through the gap lens portion 33 (textured surface). The corresponding region, that is, the region between the straight line L3 and the straight line L6 (see FIG. 2B) and the width W3 (see FIG. 2A) (hereinafter referred to as the third light emitting region A3 _I2 ) emits light. Let me.

FIG. 3B is a schematic diagram of the positional relationship between the first light emitting region A1, the second light emitting region A2, and the third light emitting region A3 _I2 when the viewpoint position is the upper position P2.

When the viewpoint position is the upper position P2, as shown in FIG. 3B, the third light emitting region A3 _I2 is located between the rear combination lamp 10 (first light emitting region A1) and the lid lamp 20 (second light emitting region A2). It is arranged in the gap S (without protruding from the gap S). Further, when the image I2 reflected on the curved surface reflecting surface 32c is transmitted through the gap lens portion 33 (textured surface), it is diffused on the textured surface and the amount of light is reduced, so that the third emission of the gap lens portion 33 (textured surface) is reduced. Regions A3 _I2 are adjusted to have the same texture as the first and second light emitting regions A1 and A2.

As described above, even when the viewpoint position is the upper position P2, the third light emitting range A3 _I2 of the gap lens portion 33 (textured surface) adjusted to have the same texture as the first and second light emitting regions A1 and A2 is rear. It is arranged in the gap S between the combination lamp 10 (first light emitting region A1) and the lid lamp 20 (second light emitting region A2) (without protruding from the gap S) (see FIG. 3B). As a result, even when the viewpoint position is the upper position P2, it is visually recognized that the first light emitting region A1 and the second light emitting region A2 are integrally (connected) to emit light.

Similarly, when the viewpoint position is the upper position P3, the image I3 reflected on the curved surface reflecting surface 32c is the image I3 of the gap lens portion 33 (textured surface) when passing through the gap lens portion 33 (textured surface). The corresponding region, that is, the region between the straight line L2 and the straight line L5 (see FIG. 2B) and the width W3 (see FIG. 2A) (hereinafter referred to as the third light emitting region A3 _I3 ) emits light. Let me.

FIG. 3C is a schematic diagram of the positional relationship between the first light emitting region A1, the second light emitting region A2, and the third light emitting region A3 _I3 when the viewpoint position is the lower position P3.

When the viewpoint position is the lower position P3, as shown in FIG. 3C, the third light emitting region A3 _I3 is located between the rear combination lamp 10 (first light emitting region A1) and the lid lamp 20 (second light emitting region A2). It is arranged in the gap S (without protruding from the gap S). Further, when the image I3 reflected on the curved surface reflecting surface 32c is transmitted through the gap lens portion 33 (textured surface), it is diffused on the textured surface and the amount of light is reduced, so that the third emission of the gap lens portion 33 (textured surface) is reduced. Regions A3 _I3 are adjusted to have the same texture as the first and second light emitting regions A1 and A2.

As described above, even when the viewpoint position is the lower position P3, the third light emitting region A3 _I3 of the gap lens portion 33 (textured surface) adjusted to have the same texture as the first and second light emitting regions A1 and A2 is rear. It is arranged in the gap S between the combination lamp 10 (first light emitting region A1) and the lid lamp 20 (second light emitting region A2) (without protruding from the gap S). As a result, even when the viewpoint position is the lower position P3, it is visually recognized that the first light emitting region A1 and the second light emitting region A2 are integrally (connected) to emit light.

Although not shown, as in the above, the first and second light emitting regions also when the viewpoint position is between the front position P1 and the upper position P2 and when the viewpoint position is between the front position P1 and the upper position P3. The third light emitting region of the gap lens portion 33 (textured surface) adjusted to have the same texture as A1 and A2 is between the rear combination lamp 10 (first light emitting region A1) and the lid lamp 20 (second light emitting region A2). It is arranged in the gap S (without protruding from the gap S). As a result, even when the viewpoint position is between the front position P1 and the upper position P2 and the viewpoint position is between the front position P1 and the upper position P3, the first light emitting region A1 and the second light emitting region A2 are generated. It is visually recognized as if it is emitting light integrally (connected).

With reference to FIGS. 3 (a) to 3 (c), although the apparent width (see, for example, the medium width LA to LC in FIG. 3) changes for each viewpoint position, the third light emitting region is irrespective of the viewpoint position. (For example, since the third light emitting region A3 _I1 to A3 _I3 ) does not protrude (do not shift) from the gap S, the first light emitting region A1 and the second light emitting region A2 are integrally (connected) to emit light. You can see that it is visible.

As described above, according to the present embodiment, the first light emitting region A1 and the second light emitting region A2 emit light integrally (connected) regardless of the viewpoint position (for example, the viewpoint positions P1 to P3). It can be visually recognized as if it were.

This is because the third light emitting region (for example, the third light emitting regions A3 _I1 to A3 _I3 formed at different positions following the viewpoint position) visually recognized through the gap S is the gap S regardless of the viewpoint position. This is because the surface shape and inclination of the curved reflective surface 32c are adjusted so as not to protrude (do not shift).

That is, as shown in FIG. 2B, the curved reflective surface 32c and the gap lens portion 33 extend downward from the lower end of the gap S and extend upward from the upper end of the gap S in the Z-axis direction. Therefore, the light reflected on the lower end side of the curved surface reflecting surface 32c and heading diagonally upward (for example, Ray2) can pass through the gap S and is reflected on the upper end side of the curved surface reflecting surface 32c. This is due to the fact that light directed diagonally downward (for example, Ray 3) can be passed through the gap S.

As a result, regardless of the viewpoint position, the third light emitting range (for example, the third light emitting area A3 _I1 to) of the gap lens portion 33 (textured surface) adjusted to have the same texture as the first and second light emitting regions A1 and A2. A3 _I3 ) is arranged in the gap S between the rear combination lamp 10 (first light emitting region A1) and the lid lamp 20 (second light emitting region A2) (without protruding from the gap S) (for example, FIG. 3 (for example). a)-See FIG. 3 (c)). This makes it possible to visually recognize that the first light emitting region A1 and the second light emitting region A2 are integrally (connected) to emit light regardless of the viewpoint position.

Next, a modification will be described.

In the above embodiment, an example using the gap lens portion 33 has been described, but the present invention is not limited to this. For example, the gap lens portion 33 may be omitted. In this case, regardless of the viewpoint position, the image I reflected on the curved reflective surface 32c is in the gap S between the rear combination lamp 10 (first light emitting region A1) and the lid lamp 20 (second light emitting region A2) (the gap). It is placed (without protruding from S). At that time, for example, by configuring the curved reflection surface 32c as a diffuse reflection surface, the image I (corresponding to the third light emitting region of the present invention) reflected on the curved reflection surface 32c is displayed in the first and second light emitting regions A1. The texture can be adjusted to the same as that of A2.

In this way, the image I reflected on the curved reflective surface 32c, which is adjusted to have the same texture as the first and second light emitting regions A1 and A2, is the rear combination lamp 10 (first) regardless of the viewpoint position. It is arranged in the gap S between the light emitting region A1) and the lid lamp 20 (second light emitting region A2) (without protruding from the gap S). As a result, even if the gap lens portion 33 is omitted, the first light emitting region A1 and the second light emitting region A2 can be visually recognized as if they are integrally (connected) to emit light regardless of the viewpoint position. ..

FIG. 4 is a vertical cross-sectional view of the vehicle lamp 30 of the modified example.

In the above embodiment, the curved reflective surface 32c and the lens portion 33 for a gap extend downward from the lower end of the gap S and extend upward from the upper end of the gap S in the Z-axis direction (FIG. 2 (FIG. 2). b) See), but it is not limited to this.

For example, as shown in FIG. 4, the portion of the curved surface reflecting surface 32c and the gap lens portion 33 extending upward from the upper end of the gap S (the portion drawn by the dotted line in FIG. 4) may be omitted.

Even in this modification, the first light emitting region A1 and the second light emitting region A2 can be visually recognized as being integrally (connected) to emit light regardless of the viewpoint position (for example, the viewpoint positions P1 and P2). can.

This is because the third light emitting region (for example, the third light emitting regions A3 _I1 to A3 _I2 formed at different positions following the viewpoint position) visually recognized through the gap S is the gap S regardless of the viewpoint position. This is because the surface shape and inclination of the curved reflective surface 32c are adjusted so as not to protrude (do not shift).

That is, as shown in FIG. 4, since the curved surface reflecting surface 32c and the gap lens portion 33 extend downward from the lower end of the gap S in the Z-axis direction, they are reflected by the lower end portion side of the curved surface reflecting surface 32c and are oblique. This is because the upward light (for example, Ray2) can be passed through the gap S.

As a result, regardless of the viewpoint position, the third light emitting range (for example, the third light emitting area A3 _I1 to) of the gap lens portion 33 (textured surface) adjusted to have the same texture as the first and second light emitting regions A1 and A2. A3 _I2 ) is arranged in the gap S between the rear combination lamp 10 (first light emitting region A1) and the lid lamp 20 (second light emitting region A2) (without protruding from the gap S) (for example, FIG. 3 (for example). a)-See FIG. 3 (b)). This makes it possible to visually recognize that the first light emitting region A1 and the second light emitting region A2 are integrally (connected) to emit light regardless of the viewpoint position.

Further, in the above embodiment, an example in which the first light emitting region A1 is formed by the rear combination lamp 10 and the second light emitting region A2 is formed by the lid lamp 20 has been described, but the present invention is not limited to this. For example, the first light emitting region A1 may be formed by a lamp other than the rear combination lamp 10, and the second light emitting region A2 may also be formed by a lamp other than the lid lamp 20.

All the numerical values shown in the above embodiments are examples, and it goes without saying that appropriate numerical values different from these can be used.

The above embodiments are merely exemplary in all respects. The present invention is not limitedly construed by the description of the above embodiment. The present invention can be practiced in various other forms without departing from its spirit or key features.
