Drawing lamp

Abstract

In a drawing lamp configured to form a light distribution pattern for drawing, the light distribution pattern for drawing can be formed without causing a sense of incongruity to the surroundings. The light emitted from the drawing unit (20) is irradiated to the front of the lamp via the light-transmitting cover (14). At this time, a reflector (40) for reflecting the light emitted from the drawing unit (20) downward is disposed between the drawing unit (20) and the light-transmitting cover (14). The mirror (40) is configured to be disposed at a position overlapping the light emitting region (A) of the drawing unit (20) in the vertical direction. Therefore, when the drawing lamp (10) is turned on, the drawing unit (20) is effectively prevented from emitting light and being seen, and useless discordance to other vehicles, pedestrians and the like is avoided.

Description

Technical Field

[0001] The present invention relates to a drawing lamp configured to form a drawing light distribution pattern. Background Art

[0002] Conventionally, as a drawing lamp for forming a drawing light distribution pattern (that is, a light distribution pattern for drawing letters, symbols, etc. on a road surface in front of a lamp), a drawing lamp configured to irradiate outgoing light from a drawing unit in front of the lamp through a light-transmitting cover is known.

[0003] In "Patent Document 1", as a drawing lamp for vehicle use, a drawing lamp configured such that a drawing unit is mounted on a vehicle in a state of being disposed obliquely downward is described.

[0004] Patent Document 1: Japanese Unexamined Patent Application Publication No. 2022-60057

[0005] By forming a drawing light distribution pattern with the irradiation light from such a drawing lamp for vehicle use, it is possible to indicate the intention of one's own vehicle to the surroundings during vehicle travel at night, etc., and thus it is possible to attract the attention of other vehicles, pedestrians, etc.

[0006] However, sometimes it is not desirable to see the drawing unit itself emitting light when the drawing lamp is lit. For example, in the case where the drawing lamp is configured to be lit synchronously with the lighting of the front turn signal, not only the front turn signal emits light and is seen at its original installation position, but also the drawing unit emits light and is seen at other positions, so there is a possibility of giving a sense of incongruity to other vehicles, pedestrians, etc. Summary of the Invention

[0007] The present invention has been made in view of such circumstances, and an object thereof is to provide a drawing lamp that can form a drawing light distribution pattern without giving a sense of incongruity to the surroundings in a drawing lamp configured to form a drawing light distribution pattern.

[0008] The present invention achieves the above object by being configured to include a predetermined mirror.

[0009] That is, the drawing lamp of the present invention is configured to form a drawing light distribution pattern on the road surface in front of the lamp by irradiating outgoing light from a drawing unit in front of the lamp through a light-transmitting cover, and is characterized in that a mirror that reflects the outgoing light from the drawing unit downward is disposed between the drawing unit and the light-transmitting cover, and the mirror is disposed in a position overlapping the light-emitting region of the drawing unit in the vertical direction.

[0010] The "drawing lamp" may be a lamp for vehicle use or a lamp for uses other than vehicle use.

[0011] If the "drawing unit" is configured such that the emitted light therefrom can form a light distribution pattern for drawing, its specific structure is not particularly limited.

[0012] If the "mirror" is configured to reflect the emitted light from the drawing unit downward in a state where it is disposed between the drawing unit and the light-transmitting cover, its specific structure such as the orientation and shape of the reflecting surface is not particularly limited.

[0013] If the "mirror" is disposed in the vertical direction at a position coinciding with the light-emitting region of the drawing unit, its specific disposition and size are not particularly limited.

[0014] The drawing lamp of the present invention is configured to irradiate the emitted light from the drawing unit forward of the lamp through the light-transmitting cover, thereby forming a light distribution pattern for drawing on the road surface in front of the lamp, and a mirror that reflects the emitted light from the drawing unit downward is disposed between the drawing unit and the light-transmitting cover, and this mirror is disposed in the vertical direction at a position coinciding with the light-emitting region of the drawing unit. Therefore, when the drawing lamp is lit, it is possible to effectively suppress the drawing unit from being seen due to its own light emission. Thus, when the drawing lamp is lit, it is possible not to bring an unnecessary sense of disharmony to other vehicles, pedestrians, etc.

[0015] In this way, according to the present invention, in a drawing lamp configured to form a light distribution pattern for drawing, it is possible to form the light distribution pattern for drawing without bringing a sense of disharmony to the surroundings.

[0016] In the above structure, if the reflecting surface of the mirror is further configured such that a plurality of reflection regions are arranged in the front-rear direction of the lamp, and on this basis, the plurality of reflection regions are configured such that the inclination angle with respect to the horizontal plane is set to a smaller value for the reflection region located more on the front side of the lamp, then it is possible to form a plurality of light distribution patterns for drawing in a tandem arrangement on the road surface in front of the lamp by the irradiation light from a single drawing unit, and thereby the function of attracting the attention of the surroundings can be improved.

[0017] At this time, if the reflecting surface of the mirror is formed such that the inclination angle gradually changes in the boundary region between the plurality of reflection regions, then it is possible to form the light distribution pattern for drawing as a series of light distribution patterns extending from the short-distance region to the long-distance region of the road surface in front of the lamp.

[0018] In the above structure, if it is further configured such that the mirror can rotate about an axis extending in the horizontal direction, then by rotating the mirror, it is possible to change the formation position of the light distribution pattern for drawing on the road surface in front of the lamp in the front-rear direction of the lamp.

[0019] At this time, if a frame portion for shielding a part of the reflected light from the mirror and restricting the irradiation range is formed at the front end portion of the mirror, it is possible to prevent stray light other than the original irradiation light from irradiating forward from the drawing unit via the light-transmitting cover in advance, and thus it is possible to clearly form a light distribution pattern for drawing. Moreover, since the frame portion rotates together with the mirror, it is possible to shield the stray light without shielding the original irradiation light.

[0020] In the above structure, as the light-transmitting cover, if a portion further below the mirror is formed into a concave portion recessed toward the rear side of the lamp, and on this basis, it is configured that the reflected light from the mirror is transmitted in the upper region of the concave portion, the following effects can be obtained.

[0021] That is, when the surface of the light-transmitting cover is dirty, when the light emitted from the drawing unit is transmitted through the light-transmitting cover, scattered light may be generated in the transmission region, thereby bringing an unnecessary sense of disharmony to the surroundings.

[0022] In response to this, if a concave portion is formed in the light-transmitting cover, since dirt is difficult to adhere to its upper region, by configuring the reflected light from the mirror to be transmitted in the upper region of the concave portion, the generation of scattered light can be effectively suppressed, and thus an unnecessary sense of disharmony can be prevented from being brought to the surroundings.

[0023] At this time, if the upper region of the concave portion is formed into a flat plate shape, the light emitted from the drawing unit can be transmitted through the light-transmitting cover in an unobstructed state as it is, and thus a light distribution pattern for drawing can be formed with good accuracy.

[0024] In the above structure, if an extension plate is further configured to be disposed between the mirror and the light-transmitting cover, when the drawing lamp is not lit, it is possible to see the mirror and the drawing unit without passing through the light-transmitting cover, and thus the aesthetic appearance of the drawing lamp can be improved. In addition, when the drawing lamp is lit, it is possible to more effectively suppress the drawing unit from being seen due to its own light emission.

[0025] At this time, if the mirror and the extension plate are integrally formed, the above effects can be obtained without increasing the number of parts.

[0026] In the above structure, if the region of the light-transmitting cover in front of the lamp of the mirror is made of a two-color molded product of an opaque resin, when the drawing lamp is not lit, it is possible to prevent the mirror and the drawing unit from being seen through the light-transmitting cover in advance, and this effect can be achieved without increasing the number of parts.

[0028] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0029] Figure 1 is a side sectional view showing the lighting fixture 10 for depiction according to an embodiment of the present invention. In addition, Figure 2 is Figure 1 the arrow view in the II direction of Figure 3 is Figure 2 the sectional view taken along line III-III of

[0030] In Figures 1 - 3 it, the direction indicated by X is "in front of the lamp", the direction indicated by Y is the "left direction" orthogonal to "in front of the lamp" (the "right direction" when viewed from the front of the lamp), and the direction indicated by Z is the "upward direction". The same applies to the figures other than Figures 1 - 3 this one.

[0031] As Figure 1 shown, the drawing lamp 10 is configured such that a drawing unit 20 and a reflector 40 are accommodated in a lamp chamber 16 formed by a lamp body 12 and a light-transmitting cover 14 attached to the front end opening of the lamp body 12. The front turn signal 50 is also accommodated in the lamp chamber 16. At this time, the drawing unit 20 and the reflector 40 are arranged in the upper region of the lamp chamber 16, and the front turn signal 50 is arranged in the lower region of the lamp chamber 16.

[0032] In addition, the drawing unit 20 and the reflector 40 are supported by a support member (not shown) on the lamp body 12. In addition, the front turn signal 50 is also supported by a support member (not shown) on the lamp body 12.

[0033] Before explaining the specific structure of the drawing lamp 10 of this embodiment, its outline will be explained.

[0034] Figure 4 、 5 are a side view and a top view showing the state where the drawing lamp 10 is mounted on the vehicle 100.

[0035] As Figure 4 、 5 shown, the drawing lamp 10 is configured to irradiate light obliquely downward toward the outside in the vehicle width direction in a state of being mounted on the side end portion in the vehicle width direction at the front end portion of the vehicle 100. That is, the drawing lamp 10 irradiates the emitted light from its drawing unit 20 in front of the lamp through the light-transmitting cover 12, thereby forming a drawing light distribution pattern PA on the road surface 2 in front of the lamp. In the drawing lamp 10, it is configured to be lit synchronously with the lighting of the front turn signal 50 of the drawing unit 20. In addition, Figure 5 shows the state where the drawing unit 20 and the front turn signal 50 of the drawing lamp 10 on the left side are lit.

[0036] As Figure 5 shown, in the state where the drawing lamp 10 is mounted on the vehicle 100, the front of the lamp is set in a direction inclined outward in the vehicle width direction with respect to the vehicle longitudinal direction.

[0037] Next, the specific structure of the drawing lamp 10 will be explained.

[0038] As Figure 1 shown, the light-transmitting cover 14 of the drawing lamp 10 is formed in a convex curved surface shape extending along the surface shape of the vehicle 100.

[0039] Moreover, in the drawing lamp 10, the light emitted from the drawing unit 20 is reflected downward by the mirror 40 disposed between the drawing unit 20 and the translucent cover 12. At this time, the mirror 40 is disposed at a position overlapping with the light emitting area A (described later) of the drawing unit 20 in the vertical direction.

[0040] As Figure 3 shown, the drawing unit 20 is configured to irradiate the light emitted from the light emitting element 22 in front of the lamp through the projection lens 26, so that the light emitted from the light emitting element 22 is incident on the mirror 40.

[0041] The projection lens 26 is a plano-convex lens with a convex curved surface on its front surface, and is supported by the lens holder 28 with its optical axis Ax extending slightly upward toward the front of the lamp.

[0042] The light emitting element 22 is a white light emitting diode, and is supported on the substrate 24 extending along a plane orthogonal to the optical axis Ax in a state of being disposed on the optical axis Ax. Moreover, the substrate 24 is supported by the heat sink 30, and the substrate 24 and the heat sink 30 are supported by the lens holder 28.

[0043] Between the light emitting element 22 and the projection lens 26, a light shielding plate 32 for shielding a part of the light from the light emitting element 22 toward the projection lens 26 is disposed. The light shielding plate 32 is supported by the lens holder 28 in a state of extending along a plane orthogonal to the optical axis Ax at the rear focal point F of the projection lens 26. An inverted trapezoidal opening 32a centered on the optical axis Ax is formed in the light shielding plate 32.

[0044] A condenser lens 34 is disposed between the substrate 24 and the light shielding plate 32. The condenser lens 34 is a biconvex lens, and is supported by the lens holder 28 at its peripheral flange portion with its optical axis coaxial with the optical axis Ax. Moreover, the condenser lens 34 is configured to make the light emitted from the light emitting element 22 enter the opening 32a of the light shielding plate 32 as light parallel to the optical axis Ax.

[0045] The mirror 40 is a plane mirror, and has a rectangular outer shape with a left-right width wider than the left-right width of the drawing unit 20. The mirror 40 is disposed in a state where its reflecting surface 40a extends obliquely upward toward the rear of the lamp. Thus, the mirror 40 reflects the light emitted from the drawing unit 20 obliquely downward and forward in a regular reflection on its reflecting surface 40a.

[0046] As described above, the mirror 40 is disposed at a position overlapping with the light emitting area A of the drawing unit 20 in the vertical direction, whereby the drawing lamp 10 is configured such that the drawing unit 20 emits light and is not visible when viewed from the front of the lamp.

[0047] That is, in the drawing unit 20, originally, only the light that exits from the light-emitting element 22 and enters the projection lens 26 as parallel light through the opening 32a of the light-shielding plate 32 is irradiated forward of the lamp. However, there is also a case where a part of the light exiting from the light-emitting element 22 becomes stray light and enters the projection lens 26. Therefore, as indicated by the dashed double-dotted line in Figure 3 , the entire area inside the outer peripheral edge of the projection lens 26 becomes the light-emitting area A, and the light-emitting area A is the maximum range in which the drawing unit 20 can emit light.

[0048] Therefore, the drawing lamp 10 is configured such that the reflecting mirror 40 is arranged in the vertical direction at a position overlapping the light-emitting area A of the drawing unit 20, so that a structure can be realized in which the drawing unit 20 emits light without being seen when viewed from the front of the lamp.

[0049] Next, Figure 4 , 5 the drawing light distribution pattern PA shown is described.

[0050] As described above, the drawing light distribution pattern PA is formed by the irradiation light from the drawing lamp 10, and the drawing light distribution pattern PA is formed as a substantially rectangular bright light distribution pattern.

[0051] The drawing light distribution pattern PA is formed as a substantially rectangular light distribution pattern because the inner peripheral edges on both the left and right sides of the opening 32a are formed to extend in a direction slightly expanding upward with respect to the vertical direction. In addition, the drawing light distribution pattern PA is formed as a bright light distribution pattern because the condenser lens 34 causes the light exiting from the light-emitting element 22 to enter the opening 32a of the light-shielding plate 32 with good efficiency.

[0052] Next, the operation of the present embodiment is described.

[0053] The drawing lamp 10 of the present embodiment is configured to irradiate the light exiting from the drawing unit 20 forward of the lamp through the light-transmitting cover 14, thereby forming the drawing light distribution pattern PA on the road surface 2 in front of the lamp. A reflecting mirror 40 that reflects the light exiting from the drawing unit 20 downward is arranged between the drawing unit 20 and the light-transmitting cover 14, and the reflecting mirror 40 is arranged in the vertical direction at a position overlapping the light-emitting area A of the drawing unit 20. Therefore, when the drawing lamp 10 is lit, it is possible to effectively suppress the drawing unit 20 from emitting light and being seen.

[0054] That is, the drawing lamp 10 of the present embodiment is configured to be lit synchronously with the lighting of the front turn signal lamp 50. At this time, it is possible to realize that the drawing unit 20 emits light without being seen, and only the front turn signal lamp 50 is seen to emit light. Thus, when the drawing lamp 10 is lit, it is possible not to give an unnecessary sense of disharmony to other vehicles, pedestrians, etc.

[0055] Thus, according to this embodiment, in the illumination device 10 configured to form the projection light distribution pattern PA, the projection light distribution pattern PA can be formed without giving an incongruous feeling to the surroundings.

[0056] At this time, in this embodiment, it is configured to form the projection light distribution pattern PA as an inverted image formed on the opening 32a of the light shielding plate 32. However, since the opening 32a has an inverted trapezoidal opening shape, a substantially rectangular projection light distribution pattern PA can be formed.

[0057] In the above embodiment, it is described that the reflector 40 has a rectangular outer shape, but it may be configured to have other outer shapes.

[0058] In the above embodiment, it is described that the opening 32a formed in the light shielding plate 32 has an inverted trapezoidal opening shape, but it may be configured to have other opening shapes (for example, an opening shape such as a V shape or a downward arrow shape).

[0059] In the above embodiment, it is described that the light emitted from the light emitting element 22 is incident on the opening 32a of the light shielding plate 32 via the condenser lens 24, but it may be configured to be directly incident on the opening 40a.

[0060] In the above embodiment, it is described that the light emitting color of the light emitting element 22 is white, but other light emitting colors (for example, amber, red, etc.) may be used.

[0061] In the above embodiment, it is described that the illumination device 10 for projection is mounted on the side end portion in the vehicle width direction at the front end portion of the vehicle 100, but it may be configured to be mounted on the rear end portion, side surface portion, etc. of the vehicle 100.

[0062] In the above embodiment, it is described that the projection light distribution pattern PA is formed on the road surface 2 in front of the illumination device by the irradiation light from the illumination device 10 for projection, but it may be configured to form the projection light distribution pattern on a wall surface arranged in front of the illumination device, a wall surface extending in front of the illumination device, etc.

[0063] Next, a modification of the above embodiment will be described.

[0064] First, a first modification of the above embodiment will be described.

[0065] Figure 6 The illumination device 110 for projection showing this modification is the same as Figure 1 the same figure.

[0066] As Figure 6As shown, the basic structure of this modification is the same as that of the above-described embodiment, but the structure of the mirror 140 is partially different from that of the above-described embodiment.

[0067] That is, the mirror 140 of this modification is also a plane mirror having a rectangular outer shape with a left-right width wider than the left-right width of the drawing unit 20, and is arranged in the vertical direction at a position overlapping with the light-emitting area A of the drawing unit 20.

[0068] In addition, in the mirror 140 of this modification, its reflecting surface 140a also extends obliquely upward toward the rear of the lamp, but the reflecting surface 140a is configured such that three reflecting areas 140a1, 140a2, and 140a3 are arranged in the front-rear direction of the lamp.

[0069] The inclination angle of the reflecting area 140a1 on the frontmost side of the lamp among the three reflecting areas 140a1 to 140a3 with respect to the horizontal plane is set to a small value, the inclination angle of the reflecting area 140a2 adjacent to the reflecting area 140a1 on the rear side of the lamp with respect to the horizontal plane is set to a value larger than the inclination angle of the reflecting area 140a1, and the inclination angle of the reflecting area 140a3 adjacent to the reflecting area 140a2 on the rear side of the lamp with respect to the horizontal plane is set to a value larger than the inclination angle of the reflecting area 140a2.

[0070] Moreover, in the drawing lamp 110 of this modification, by reflecting the light emitted from the drawing unit 20 downward by the mirror 140, it is possible to form a drawing light distribution pattern PB composed of three drawing light distribution patterns PB1, PB2, and PB3 on the road surface 2 in front of the lamp.

[0071] Figure 8 FIG. (a) shows a top view of the state where the drawing lamp 110 is mounted on the vehicle 100.

[0072] As also shown in Figure 8 FIG. (a), the drawing light distribution pattern PB is formed such that three drawing light distribution patterns PB1, PB2, and PB3 are arranged in series at intervals. All of these three drawing light distribution patterns PB1 to PB3 are formed as light distribution patterns shorter in the front-rear direction of the lamp than the drawing light distribution pattern PA formed in the above-described embodiment, but the drawing light distribution pattern PB as a whole is formed as a light distribution pattern longer in the front-rear direction of the lamp than the drawing light distribution pattern PA.

[0073] In this modification, since the mirror 140 is also arranged in the vertical direction at a position overlapping with the light-emitting area A of the drawing unit 20, it is possible to form the drawing light distribution pattern PB without giving an incongruous feeling to the surroundings.

[0074] On this basis, in this modification example, the reflecting surface 140a of the reflector 140 is configured such that three reflection regions 140a1 to 140a3 are arranged in the front-rear direction of the lamp, and the inclination angle with respect to the horizontal plane is set to a smaller value for the reflection region closer to the front side of the lamp. Therefore, three illumination distribution patterns PB1 to PB3 for drawing can be formed in a tandem arrangement on the road surface 2 in front of the lamp by the illumination light from a single drawing unit 20, thereby enhancing the function of attracting the attention of the surroundings.

[0075] In the first modification example, it has been described that the reflecting surface 140a of the reflector 140 has three reflection regions 140a1 to 140a3, but it may also be configured to have two or four or more reflection regions.

[0076] Next, a second modification example of the above-described embodiment will be described.

[0077] Figure 7 The drawing lamp 210 showing this modification example is the same as Figure 1 the same figure.

[0078] As Figure 7 shown, the basic structure of this modification example is the same as that of the above-described embodiment, but the structure of the reflector 240 is partially different from that of the above-described embodiment.

[0079] That is, the reflector 240 of this modification example is also a flat mirror having a rectangular outer shape with a left-right width wider than the left-right width of the drawing unit 20, and is arranged in the up-down direction at a position overlapping with the light-emitting region A of the drawing unit 20.

[0080] In addition, in the reflector 240 of this modification example, its reflecting surface 240a also extends obliquely upward toward the rear of the lamp, but the reflecting surface 240a is configured such that three reflection regions 240a1, 240a2, and 240a3 are arranged in the front-rear direction of the lamp.

[0081] At this time, the three reflection regions 240a1 to 240a3 are the same as those in the first modification example, and the inclination angles with respect to the horizontal plane gradually increase in this order. However, in the boundary regions between the three reflection regions 240a1 to 240a3, the inclination angles are formed to gradually change, whereby the three reflection regions 240a1 to 240a3 are formed into a substantially single convex columnar curved surface shape.

[0082] Moreover, in the drawing lamp 210 of this modification example, the emitted light from the drawing unit 20 is reflected downward by the reflector 240, thereby forming an illumination distribution pattern PC for drawing on the road surface 2 in front of the lamp.

[0083] Figure 8Fig. (b) is a top view showing the state where the drawing lamp 210 is mounted on the vehicle 100.

[0084] Also as Figure 8 shown in Fig. (b), the drawing light distribution pattern PC is formed as a single light distribution pattern that is longer in the front-rear direction of the lamp than the drawing light distribution pattern PA formed in the above-described embodiment.

[0085] In this modified example, since the mirror 240 is also arranged in the vertical direction at a position overlapping with the light-emitting area A of the drawing unit 20, the drawing light distribution pattern PC can be formed without giving a sense of incongruity to the surroundings.

[0086] On this basis, in this modified example, the reflecting surface 240a of the mirror 240 is configured such that the inclination angle gradually changes in the boundary areas between the three reflecting areas 240a1 to 240a3. Therefore, the drawing light distribution pattern PC can be formed as a series of light distribution patterns extending from the short-distance area to the long-distance area of the road surface in front of the lamp, thereby improving the function of attracting the attention of the surroundings.

[0087] Next, a third modified example of the above-described embodiment will be described.

[0088] Figure 9 The drawing lamp 310 showing this modified example is the same figure as Figure 1 the same.

[0089] As Figure 9 shown, the basic structure of this modified example is the same as that of the above-described embodiment, but the structure of the mirror 340 is partially different from that of the above-described embodiment.

[0090] That is, the mirror 340 of this modified example is also a plane mirror having a rectangular outer shape with a left-right width wider than the left-right width of the drawing unit 20, and is arranged in the vertical direction at a position overlapping with the light-emitting area A of the drawing unit 20.

[0091] Moreover, in the drawing lamp 310 of this modified example, the emitted light from the drawing unit 20 is reflected downward by the mirror 340, so that a drawing light distribution pattern PD can be formed on the road surface 2 in front of the lamp.

[0092] The mirror 340 of this modified example is configured to be rotatable about an axis Ax1 extending in the horizontal direction at its front end. Moreover, the mirror 340 is rotated about the axis Ax1 by being driven by an actuator (not shown). In addition, in Figure 9 , the state where the mirror 340 is rotated to the upper side is indicated by a dashed line, and the state where the mirror 340 is rotated to the lower side is indicated by a double-dot chain line.

[0093] In addition, at the front end of the mirror 340 in this modified example, a frame portion 342 for shielding a part of the reflected light from the reflecting surface 340a to limit the irradiation range is integrally formed with the mirror 340. The frame portion 342 is formed to protrude downward from the mirror 340, and a rectangular opening 342a is formed by the frame portion 342 and the mirror 340.

[0094] Figure 10 FIG. is a plan view showing a state where the drawing lamp 310 is mounted on the vehicle 100.

[0095] Also as Figure 10 shown, the drawing light distribution pattern PD is formed into the same light distribution pattern as the drawing light distribution pattern PA formed in the above-described embodiment. However, by rotating the mirror 340 about the axis Ax1, the formation position of the drawing light distribution pattern PD on the road surface 2 in front of the lamp can be changed in the front-rear direction of the lamp.

[0096] In this modified example, since the mirror 340 is also disposed in the vertical direction at a position overlapping the light emitting region A of the drawing unit 20, the drawing light distribution pattern PD can be formed without giving an incongruous feeling to the surroundings.

[0097] On this basis, in this modified example, by rotating the mirror 340 about the axis Ax1, the formation position of the drawing light distribution pattern PD on the road surface 2 in front of the lamp can be changed in the front-rear direction of the lamp as needed.

[0098] In addition, in this modified example, since the frame portion 342 is formed at the front end of the mirror 340, it is possible to prevent in advance stray light other than the original irradiation light from being irradiated forward of the lamp from the drawing unit 20 via the light transmissive cover 14, and thus the drawing light distribution pattern PD can be clearly formed. Moreover, since the frame portion 342 rotates together with the mirror 340, it is possible to shield the stray light without shielding the original irradiation light.

[0099] Next, a fourth modified example of the above-described embodiment will be described.

[0100] Figure 11 The drawing lamp 410 showing this modified example is the same as Figure 1 the same figure.

[0101] As Figure 11 shown, the basic structure of this modified example is the same as that of the above-described embodiment, but the structure of the light transmissive cover 414 is partially different from that of the above-described embodiment.

[0102] That is, the portion of the light-transmitting cover 414 of this modification that is located further below than the reflecting mirror 40 is formed into a recess 414a that is recessed toward the rear side of the lamp. Moreover, by causing the reflected light from the reflecting mirror 40 to transmit through the upper region 414a1 of the recess 414a, it is possible to form the drawing light distribution pattern PA on the road surface 2 in front of the lamp.

[0103] The recess 414a has a wedge-shaped vertical cross-sectional shape, and its upper region 414a1 is formed to extend in a flat plate shape in a direction that is slightly inclined obliquely upward toward the rear side of the lamp with respect to the horizontal plane. In addition, the lower region 414a2 of the recess 414a is formed at an inclination angle at which the reflected light from the reflecting mirror 40 does not enter.

[0104] By adopting the structure of this modification, the following effects can be obtained.

[0105] That is, when the surface of the light-transmitting cover 414 is dirty, scattered light may be generated in the transmission region when the emitted light from the drawing unit 20 transmits through the light-transmitting cover 414, thereby bringing an unnecessary sense of disharmony to the surroundings.

[0106] In contrast, by forming the recess 414a in the light-transmitting cover 414 as in this modification, dirt is less likely to adhere to its upper region 414a1. Therefore, by configuring the reflected light from the reflecting mirror 40 to transmit through the upper region 414a1 of the recess 414a, the generation of scattered light can be effectively suppressed, and thus an unnecessary sense of disharmony can be prevented from being brought to the surroundings.

[0107] Moreover, since the upper region 414a1 of the recess 414a is formed in a flat plate shape, the emitted light from the drawing unit 20 can transmit through the light-transmitting cover 414 in an unobstructed state as it is, and thus the drawing light distribution pattern PA can be formed with good accuracy.

[0108] Furthermore, since the upper region 414a1 of the recess 414a extends in a direction that is slightly inclined obliquely upward toward the rear side of the lamp with respect to the horizontal plane, it is possible to prevent the upper region 414a1 from being seen from the front direction of the lamp, and thus it is possible to prevent the light-transmitting cover 414 from being accidentally seen to emit light when the drawing unit 20 is lit.

[0109] Next, a fifth modification of the above-described embodiment will be described.

[0110] Figure 12 The drawing lamp 510 showing this modification is the same as Figure 1 the same figure.

[0111] As Figure 12As shown, the basic structure of this modified example is the same as that of the above-described embodiment, but it is different from the above-described embodiment in that an extension plate 560 is additionally arranged in the lamp chamber 16.

[0112] The extension plate 560 is arranged between the reflector 40 and the transparent cover 14 so as to extend along the transparent cover 14. The lower end surface of the extension plate 560 is located more on the lower side than the front end surface of the reflector 40, and its upper end surface is located at the front end portion of the lamp body 12.

[0113] By adopting the structure of this modified example, the following effects can be obtained.

[0114] That is, when the drawing lamp 510 is not lit, it is possible to see the reflector 40 and the drawing unit 20 without passing through the transparent cover 14, thereby improving the aesthetic appearance of the drawing lamp 510. In addition, when the drawing lamp 510 is lit, it is possible to more effectively suppress the drawing unit 20 from being seen due to its own light emission.

[0115] Next, a sixth modified example of the above-described embodiment will be described.

[0116] Figure 13 (a) of shows the drawing lamp 610 of this modified example, which is the same as Figure 1 the same figure.

[0117] As Figure 13 shown in (a) of, the basic structure of this modified example is the same as that of the above-described embodiment, but it is different from the above-described embodiment in that an extension plate 660 is additionally arranged in the lamp chamber 16.

[0118] The extension plate 660 is arranged between the reflector 640 and the transparent cover 14 so as to extend along the transparent cover 14 in the same manner as in the fifth modified example. However, in this modified example, the extension plate 660 is integrally formed with the reflector 640.

[0119] That is, the front end portion of the reflector 640 and the lower end portion of the extension plate 660 are connected near the transparent cover 14. The upper end portion 660a of the extension plate 660 extends at a slightly upward inclination angle with respect to the reflector 640, and its upper end surface is located at the front end portion of the lamp body 12.

[0120] In addition, the reflecting surface 640a of the reflector 640 is arranged in a state of extending obliquely upward toward the rear of the lamp in the same manner as in the above-described embodiment.

[0121] In the case of adopting the structure of this modified example, similar to the case of the fifth modified example, when the drawing light fixture 610 is not lit, it is possible to see the reflector 640 and the drawing unit 20 without passing through the light-transmitting cover 14, thereby improving the aesthetic appearance of the drawing light fixture 610. In addition, when the drawing light fixture 610 is lit, it is possible to more effectively suppress the drawing unit 20 from being seen due to its own light emission.

[0122] Moreover, by configuring the reflector 640 and the extension plate 660 to be integrally formed as in this modified example, the above-described effects can be obtained without increasing the number of parts.

[0123] Next, a seventh modified example of the above-described embodiment will be described.

[0124] Figure 13 (b) of represents the drawing light fixture 710 of this modified example, which is the same as Figure 1 the same figure.

[0125] As Figure 13 shown in (b) of, the basic structure of this modified example is the same as that of the above-described embodiment, but the structure of the light-transmitting cover 714 is partially different from that of the above-described embodiment.

[0126] That is, the upper region 714b of the light-transmitting cover 714 of this modified example, which is in front of the light fixture of the reflector 40, is formed of a two-color molded product made of opaque resin.

[0127] In the case of adopting the structure of this modified example, similar to the case of the fifth modified example, when the drawing light fixture 710 is not lit, it is possible to see the reflector 40 and the drawing unit 20 without passing through the light-transmitting cover 714, thereby improving the aesthetic appearance of the drawing light fixture 710. In addition, when the drawing light fixture 710 is lit, it is possible to more effectively suppress the drawing unit 20 from being seen due to its own light emission.

[0128] Moreover, by forming the light-transmitting cover 714 of a two-color molded product as in this modified example, the above-described effects can be obtained without increasing the number of parts.

[0129] In addition, the numerical values shown as specifications in the above-described embodiment and its modified examples are merely examples, and of course, they can be appropriately set to different values.

[0130] Furthermore, the present invention is not limited to the structures described in the above-described embodiment and its modified examples, and structures with various modifications other than these can be adopted.

[0131] This international application claims the priority of Japanese Patent Application No. 2022-186955 filed on November 22, 2022, and incorporates the entire contents of Japanese Patent Application No. 2022-186955 in this international application.

They are comprehensive and are not intended to limit the present invention to the described manner itself. Numerous modifications and variations can be made with reference to the above description, which will be obvious to those skilled in the art. Description of Reference Numerals
