[0009] The vehicle light fixture according to claim 1 comprises a lens comprising a first lens segment, a second lens segment, and a third lens segment. The central vertical lens segment of the first, second, and third lens segments is formed using point perspective so that it has a vanishing point towards the center of the vehicle, creating a sense of depth. Furthermore, by making the width of the second lens segment narrower than the width of the first lens segment, and the width of the third lens segment narrower than the width of the second lens segment, the lens segments become narrower at a uniform rate as they recede into the distance, creating a sense of depth. Furthermore, the brightness of the second lens segment is lower than that of the first lens segment, and the brightness of the third lens segment is lower than that of the second lens segment, so that the lens segments become darker at a uniform rate as they recede into the distance, creating a sense of depth. By synergistically combining point perspective, lens segment width, and lens segment brightness settings, a sense of depth can be created that exceeds the actual thickness of the vehicle light fixture.

[0016] FIG. 4(A) is an explanatory diagram of the vehicular lamp according to the first embodiment. The portion of the first lens segment horizontal plate 22H exposed by the first slit 32 of the panel 30 provided on the first lens segment 22 shown in FIG. 3 forms the first area E1 (the first lens segment 22) in FIG. 4(A). The portion exposed by the second slit 34 of the panel 30 provided on the second lens segment horizontal plate 24H forms the second area E2 (the second lens segment 24). The portion exposed by the third slit 36 of the panel 30 provided on the third lens segment horizontal plate 26H forms the third area E3 (the third lens segment 26). The portion exposed by the fourth slit 38 of the panel 30 provided on the fourth lens segment 28 forms the fourth area E4 (the fourth lens segment 28). The fourth slit 38 is provided only on the outer side of the fourth lens segment horizontal plate 28H.

[0017] FIG. 4(A) is an explanatory diagram of the vanishing point of the vehicular lamp according to the first embodiment by the perspective projection drawing method. The substantially U-shaped first lens segment 22 is composed of a central vertical lens segment 22v in the form of a vertical flat plate, an upper horizontal lens segment 22h1 in the form of a horizontal flat plate extending from the upper end of the central vertical lens segment 22v toward the vehicle center side, and a lower horizontal lens segment 22h2 in the form of a horizontal flat plate extending from the lower end of the central vertical lens segment 22v toward the vehicle center side. The upper end side of the central vertical lens segment 22v is slightly inclined toward the vehicle center side. Although the drawing shows a tail lamp mounted on the left side of the vehicle, in the tail lamp on the side mounted on the right side of the vehicle (not shown), the central vertical lens segment is inclined in the opposite direction. The angle between the central vertical lens segment 22v and the upper horizontal lens segment 22h1 is an obtuse angle, and the upper horizontal lens segment 22h1 is inclined at approximately 45 degrees with respect to the vertical direction. The angle between the central vertical lens segment 22v and the lower horizontal lens segment 22h2 is an obtuse angle, and the upper horizontal lens segment 22h1 is inclined at approximately 135 degrees with respect to the vertical direction. The first lens segment 22 is exposed through the first slit 32 of the panel 30 to form the first area E1.

[0018] The second lens segment 24 is substantially similar in shape to the first lens segment 22 and comprises a central vertical lens segment 24v, an upper horizontal lens segment 24h1, and a lower horizontal lens segment 24h2, and is located inside the first lens segment 22. The second lens segment 24 is exposed by the second slit 34 of the panel 30, forming the second area E2.

[0019] The third lens segment 26 is substantially similar in shape to the second lens segment 24 and comprises a central vertical lens segment 26v, an upper horizontal lens segment 26h1, and a lower horizontal lens segment 26h2, and is located inside the second lens segment 24. The third lens segment 26 is exposed by the third slit 36 ​​of the panel 30, forming the third area E3.

[0020] The fourth lens segment 28 is substantially similar in shape to the third lens segment 26 and comprises a central vertical lens segment 28v, an upper horizontal lens segment 28h1, and a lower horizontal lens segment 28h2, and is located inside the third lens segment 26. The fourth lens segment 28 is exposed by the fourth slit 38 of the panel 30, forming the fourth area E4.

[0021] The central vertical lens segment 22v of the first lens segment 22, the central vertical lens segment 24v of the second lens segment 24, the central vertical lens segment 26v of the third lens segment 26, and the central vertical lens segment 28v of the fourth lens segment 28 are formed using point perspective so that the vanishing point X1 is located towards the center of the vehicle.

[0022] In other words, the line segment LI1 connecting the outer peripheral angle A1l and the inner peripheral angle A1s of the central vertical lens segment 22v and the upper horizontal lens segment 22h1 of the first lens segment 22, and the line segment LI2 connecting the outer peripheral angle A1L and the inner peripheral angle A1S of the central vertical lens segment 22v and the lower horizontal lens segment 22h2 of the first lens segment 22, intersect at the vanishing point X1.

[0023] Furthermore, line segment LI1 connects the outer peripheral angle A2l and the inner peripheral angle A2s between the central vertical lens segment 24v and the upper horizontal lens segment 24h1 of the second lens segment 24, the outer peripheral angle A3l and the inner peripheral angle A3s between the central vertical lens segment 26v and the upper horizontal lens segment 26h1 of the third lens segment 26, and the outer peripheral angle A4l and the inner peripheral angle A4s between the central vertical lens segment 28v and the upper horizontal lens segment 28h1 of the fourth lens segment 28.

[0024] The line segment LI2 connects the outer peripheral angle A2L and the inner peripheral angle A2S between the central vertical lens segment 24v and the lower horizontal lens segment 24h2 of the second lens segment 24, the outer peripheral angle A3L and the inner peripheral angle A3S between the central vertical lens segment 26v and the lower horizontal lens segment 26h2 of the third lens segment 26, and the outer peripheral angle A4L and the inner peripheral angle A4S between the central vertical lens segment 28v and the lower horizontal lens segment 28h2 of the fourth lens segment 28.

[0025] In the vehicle lighting fixture of the first embodiment, the central vertical lens segments 22v, 24v, 26v, and 28v of the first lens segment 22, second lens segment 24, third lens segment 26, and fourth lens segment 28 that constitute the lens 20 are formed using point perspective so that the vanishing point X1 is on the side of the center of the vehicle, thereby creating a sense of depth.

[0026] Figure 4(B) is an explanatory diagram of the thickness (width) of the segment in the first embodiment. The width W2 of the second lens segment 24 is narrower than the width W1 of the first lens segment 22. The width W3 of the third lens segment 26 is narrower than the width W2 of the second lens segment 24. The width W4 of the fourth lens segment 28 is narrower than the width W3 of the third lens segment 26. Here, if the ratio of width W2 to width W1 is 1:0.7, then the ratio of width W3 to width W2, and the ratio of width W4 to width W3 are set to 1:0.7. If the ratio of width W2 to width W1 is 1:0.6, then the ratio of width W3 to width W2, and the ratio of width W4 to width W3 are set to 1:0.6. In other words, the lens segments become narrower at a uniform rate as you move further back.

[0027] In the vehicle light fixture 10 of the first embodiment, the width W2 of the second lens segment 24 is narrower than the width W1 of the first lens segment 22, the width W3 of the third lens segment 26 is narrower than the width W2 of the second lens segment 24, and the width W4 of the fourth lens segment 28 is narrower than the width W3 of the third lens segment 26. Therefore, in the vehicle light fixture 10 of the first embodiment, the lens segments become narrower at a uniform rate as you move further back, creating a sense of depth.

[0028] Figure 4(C) is an explanatory diagram of the brightness of the segment in the first embodiment. The brightness of the second lens segment 24 is lower than that of the first lens segment 22, the brightness of the third lens segment 26 is lower than that of the second lens segment 24, and the brightness of the fourth lens segment 28 is lower than that of the third lens segment 26.

[0029] Figure 6 is a diagram showing the brightness of the segments in the first embodiment. The brightness of the first lens segment (area E1) 22 is 56 cd, the brightness of the second lens segment (area E2) 24 is 38 cd, the brightness of the third lens segment (area E3) 26 is 21 cd, and the brightness of the fourth lens segment (area E4) 28 is 9 cd. In other words, the lens segments are set to become darker at a uniform rate as you move further back in the image.

[0030] The brightness of the second lens segment (area E2) 24 is adjusted by changing the angle of the first inner inclined wall 22sr on the inner side of the first lens segment horizontal plate 22H shown in Figure 5, thereby adjusting the amount of light reflected towards the second vertical wall 212. The brightness of the third lens segment (area E3) 26 is adjusted by changing the angle of the second inner inclined wall 24sr on the inner side of the second lens segment horizontal plate 24H shown in Figure 5, thereby adjusting the amount of light reflected towards the third vertical wall 213. The brightness of the fourth lens segment (area E4) 28 is adjusted by changing the angle of the third inner inclined wall 26sr on the inner side of the third lens segment horizontal plate 26H shown in Figure 5, thereby adjusting the amount of light reflected towards the fourth vertical wall 214.

[0031] In the vehicle lighting fixture 10 of the first embodiment, the brightness of the second lens segment 24 is lower than that of the first lens segment 22, the brightness of the third lens segment 26 is lower than that of the second lens segment 24, and the brightness of the fourth lens segment 28 is lower than that of the third lens segment 26. As you move further into the distance, the lens segments become darker at a uniform rate, creating a sense of depth.

[0032] In the vehicle light fixture 10 of the first embodiment, by synergistically combining the point perspective method shown in Figure 4(A), the width of the lens segment shown in Figure 4(B), and the brightness setting of the lens segment shown in Figure 4(C), it is possible to create a sense of depth that exceeds the actual thickness of the vehicle light fixture.

[0033] [Second Embodiment] The vehicle lighting fixture of the second embodiment has the same structure as the first embodiment described above, except for the shape of the lens, as shown in Figures 1 to 3. Figure 7(A) is an explanatory diagram of the vanishing point of the vehicle lamp of the second embodiment using point perspective. The lens 20 of the vehicle lamp of the second embodiment consists of a roughly U-shaped first lens segment 22, a second lens segment 24, a third lens segment 26, and a fourth lens segment 28, similar to the first embodiment. Each lens segment consists of a central vertical lens segment 22v, 24v, 26v, 28v, an upper horizontal lens segment 22h1, 24h1, 26h1, 28h1, and a lower horizontal lens segment 22h2, 24h2, 26h2, 28h2. The second lens segment 24 is roughly similar in shape to the first lens segment 22 and is provided inside the first lens segment 22. The third lens segment 26 is roughly similar in shape to the second lens segment 24 and is provided inside the second lens segment 24. The fourth lens segment 28 is substantially similar in shape to the third lens segment 26 and is located inside the third lens segment 26.

[0034] The central vertical lens segment 22v of the first lens segment 22, the central vertical lens segment 24v of the second lens segment 24, the central vertical lens segment 26v of the third lens segment 26, and the central vertical lens segment 28v of the fourth lens segment 28 are formed using point perspective so that the vanishing point X1 is on the side of the vehicle's center. In the vehicle lighting fixture of the second embodiment, the central vertical lens segments 22v, 24v, 26v, and 28v of the lens segments are formed using point perspective so that the vanishing point X1 is on the side of the vehicle's center, thus creating a sense of depth.

[0035] Figure 7(B) is an explanatory diagram of the segment width and point light of the second embodiment. In the vehicle lighting fixture of the second embodiment, similar to the first embodiment, the width W2 of the second lens segment 24 is narrower than the width W1 of the first lens segment 22, the width W3 of the third lens segment 26 is narrower than the width W2 of the second lens segment 24, and the width W4 of the fourth lens segment 28 is narrower than the width W3 of the third lens segment 26. Therefore, in the vehicle lighting fixture 10 of the second embodiment, the lens segments become narrower at a uniform rate as they move further back, creating a sense of depth.

[0036] Figure 7(C) is an explanatory diagram of the brightness of the segment in the second embodiment. The brightness of the second lens segment 24 is lower than that of the first lens segment 22, the brightness of the third lens segment 26 is lower than that of the second lens segment 24, and the brightness of the fourth lens segment 28 is lower than that of the third lens segment 26. In the vehicle lighting fixture of the second embodiment, similar to the first embodiment, the lens segments become darker at a uniform rate as they move further back, creating a sense of depth.

[0037] In the vehicle lighting fixture 10 of the second embodiment, by synergistically combining the point perspective method shown in Figure 7(A), the width of the lens segment shown in Figure 7(B), and the brightness setting of the lens segment shown in Figure 7(C), it is possible to create a sense of depth that exceeds the actual thickness of the vehicle lighting fixture.

[0038] In the vehicle lighting device of the second embodiment, as shown in Figure 7(B), point illumination BR is generated in the first lens segment 22, second lens segment 24, third lens segment 26, and fourth lens segment 28, corresponding to the arranged LEDs. Here, point illumination refers to the phenomenon where a portion of the light from the light source (LED) is emitted directly, shining brighter than the surrounding area. Figure 8 is an explanatory diagram showing the transmission of light within the lens of the vehicle lamp of the second embodiment. Light from LED 60 is reflected from the first vertical wall 211 toward the first lens segment horizontal plate 22H, generating a point of light BR at the first outer inclined wall 22sl. Furthermore, light from the second vertical wall 212 is reflected toward the second lens segment horizontal plate 24H, generating a point of light BR at the second outer inclined wall 24sl. Light from the third vertical wall 213 is reflected toward the third lens segment horizontal plate 26H, generating a point of light BR at the third outer inclined wall 26sl. Light from the fourth vertical wall 214 is reflected toward the fourth lens segment horizontal plate 28H, generating a point of light BR at the fourth outer inclined wall 28sl.

[0039] In many vehicle lighting fixtures, the point light is made less conspicuous by adding steps to the lens or providing an aperture to the lens, thereby concealing the light source itself. In the second embodiment, the point light is deliberately made conspicuous.

[0040] Furthermore, in the second embodiment, the first lens segment 22, the second lens segment 24, the third lens segment 26, and the fourth lens segment 28 are provided with a convex lens-shaped (fish cake-shaped) R-shape on their surfaces, so that the brightness changes as the line of sight moves, creating a sparkling effect.

[0041] In the vehicle lighting of the second embodiment, the point light is deliberately made to stand out, and the brightness changes as the viewer's gaze moves, creating a sparkling effect, which makes it possible to add an accent to the sense of depth. [Explanation of Symbols]
