Vehicle lighting

Abstract

Even when multiple luminaire units are housed in a lamp chamber formed by a lamp body and a translucent cover, arranged in a line in the vehicle width direction, and these units are positioned to be sequentially displaced towards the rear of the luminaires outward in the vehicle width direction, the configuration ensures sufficient heat dissipation performance and wiring space for power supply connectors for each unit. [Solution] Each of the three lighting units 20A, 20B, and 20C is configured to include a light-emitting unit 40 supported by a metal plate 30 and a reflector 60 that reflects the emitted light toward the front of the lighting unit. The metal plate 30 is formed such that a vertical wall portion 34 bends downward from the main body portion 32, and a notch 34a is formed on the outer end face 34d in the vehicle width direction of this vertical wall portion 34 to avoid interference with the power supply connector 70. This makes it possible to secure wiring space for the power supply connector 70 even if the width of the metal plate 30 is narrow.

Summary of the Invention

Problems to be Solved by the Invention

[0007] As described in "Patent Document 1" and "Patent Document 2" above, by providing a main body portion and a vertical wall portion as the metal plate configuration for each of the multiple lighting units, it is possible to improve the heat dissipation performance.

[0008] However, in vehicle lighting fixtures where multiple lighting units are arranged in a line in the vehicle width direction and are sequentially displaced towards the rear of the lighting fixtures outward in the vehicle width direction, if the spacing between the multiple lighting units becomes large in the front-to-rear direction of the lighting fixtures, it becomes difficult to secure sufficient width for the metal plates in the configuration of each of the multiple lighting units, and therefore it also becomes difficult to secure space for wiring the power supply connectors.

[0009] The present invention has been made in view of these circumstances, and aims to provide a vehicle lighting device in which a plurality of lighting units are housed in a lamp chamber formed by a lamp body and a light-transmitting cover, arranged in the vehicle width direction, and even when the plurality of lighting units are arranged to be sequentially displaced toward the rear of the lighting device toward the outside in the vehicle width direction, the present invention can ensure heat dissipation performance and wiring space for power supply connectors for each of them. [Means for solving the problem]

[0010] The present invention aims to achieve the above objective by modifying the structure of the metal plate.

[0011] In other words, the vehicle lighting device according to the present invention is In a vehicle lighting fixture in which multiple lighting units are housed in a configuration arranged in the vehicle width direction within a lighting chamber formed by a lamp body and a translucent cover, The above-mentioned multiple lighting units are arranged so as to be sequentially displaced towards the rear of the lighting unit, outward in the vehicle width direction. Each of the above-mentioned multiple lighting units comprises a light-emitting unit supported by a metal plate and a reflector that reflects the light emitted from the light-emitting unit toward the front of the lighting fixture. The above metal plate comprises a main body and a vertical wall portion formed to bend vertically from the main body. The above-mentioned light-emitting unit is configured to be electrically connected to the power supply connector while being supported by the main body. The present invention is characterized in that a notch is formed on the outer end face in the vehicle width direction of the vertical wall portion to avoid interference with the power supply connector.

[0012] The specific arrangement of the "multiple lighting units" described above is not particularly limited, as long as they are arranged in a line in the vehicle width direction and are sequentially displaced towards the rear of the lighting unit toward the outside in the vehicle width direction.

[0013] The above-mentioned "vertical wall portion" may be formed to bend in either the vertical or vertical direction from the main body portion.

[0014] The "notch" described above is formed on the outer end face in the vehicle width direction of the vertical wall in a manner that avoids interference with the power supply connector, but the specific shape of the notch is not particularly limited. [Effects of the Invention]

[0015] The vehicle lighting device according to the present invention houses a plurality of lighting units arranged in the vehicle width direction and sequentially displaced towards the rear of the lighting unit outward in the vehicle width direction within a lighting chamber formed by a lamp body and a light-transmitting cover. Each of these units comprises a light-emitting unit and a reflector supported by a metal plate. The metal plate has a main body and a vertical wall portion formed to bend vertically from the main body, thereby improving its heat dissipation performance.

[0016] Furthermore, since the vertical wall portion of the metal plate has a notch formed on its outer end face in the vehicle width direction to avoid interference with the power supply connector, even if the width of the metal plate is narrowed due to the arrangement of multiple lighting units so that they are sequentially displaced towards the rear of the lighting unit in the outward direction of the vehicle width, space for connecting the power supply connector can be secured.

[0017] Thus, according to the present invention, in a vehicle lighting fixture in which a plurality of lighting units are housed in a lamp chamber formed by a lamp body and a light-transmitting cover, even when the plurality of lighting units are arranged to be sequentially displaced toward the rear of the lighting fixture toward the outside in the vehicle width direction, it is possible to secure heat dissipation performance and wiring space for power supply connectors for each of them.

[0018] In the above configuration, if the spacing between multiple lighting units is set such that the spacing in the front-to-rear direction of the lighting units is greater than the spacing in the vehicle width direction, it becomes even more difficult to secure sufficient width for the metal plate in each of the multiple lighting units. Consequently, it becomes even more difficult to secure space for wiring the power supply connector. Therefore, adopting the configuration of the present invention is particularly effective.

[0019] In the above configuration, if the metal plate is further fixed to the reflector at three locations on the main body, and these three locations are set at two locations on the left and right of the front region of the main body and one location at the rear of the inner region in the vehicle width direction, the metal plate can be stably fixed in a limited space. Moreover, the one location at the rear of the inner region in the vehicle width direction of the main body is located at the part that connects to the base end of the vertical wall, which has a notch formed on its outer end face in the vehicle width direction, so sufficient support rigidity for the vertical wall can be ensured.

[0020] In this case, if the metal plate is fixed to the reflector at the three locations mentioned above by heat crimping, the metal plate can be securely fixed without increasing the number of lighting fixture components.

[0021] In the above configuration, further, if the main body portion of the metal plate is formed such that the end face on the outer side in the vehicle width direction extends in a tapered shape toward the front end face, even if a plurality of lamp units are arranged so as to be sequentially displaced toward the rear side of the lamp in the vehicle width direction, it is easily possible to secure a required interval between the metal plate and the light-transmitting cover.

[0022] In the above configuration, further, if the reflector constituting each of the plurality of lamp units is formed as an integrally molded product, the metal plates of each of the plurality of lamp units can be configured to be supported by a common reflector assembly, and thereby it is easily possible to secure a space for arranging the metal plates.

Mode for Carrying Out the Invention

[0024] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0025] FIG. 1 is a plan sectional view showing a vehicle lamp 10 according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along line II-II of FIG. 1.

[0026] In FIGS. 1 and 2, the direction indicated by X is “front of the lamp”, the direction indicated by Y is “left direction” (in the front view of the lamp, it is “right direction”) orthogonal to “front of the lamp”, and the direction indicated by Z is “upward direction”. The same applies to the figures other than FIGS. 1 and 2.

[0027] As shown in Figures 1 and 2, the vehicle light fixture 10 according to this embodiment is configured as a low-beam headlamp mounted on the left front end of the vehicle. This vehicle light fixture 10 has a configuration in which three light fixture units 20A, 20B, and 20C are housed in a lamp chamber formed by a lamp body 12 and a transparent light-transmitting cover 14 attached to the front end opening of the lamp body 12, arranged in the left-right direction (i.e., in the vehicle width direction). Note that in Figure 1, only the lamp body 12 and the light-transmitting cover 14 are shown, with the upper region cut off.

[0028] The translucent cover 14 is formed to extend from its right side (i.e., the inner side in the vehicle width direction) to the left side, sloping sharply toward the rear of the lamp.

[0029] The three luminaire units 20A to 20C are arranged so that they are sequentially displaced towards the rear of the luminaires, outward in the vehicle width direction. In this arrangement, the spacing between these three luminaire units 20A to 20C is set such that the spacing in the front-to-rear direction is greater than the spacing in the vehicle width direction (specifically, about 1.4 to 2 times greater).

[0030] The three luminaire units 20A to 20C all have substantially the same configuration. That is, each of these three luminaire units 20A to 20C is equipped with a light-emitting unit 40 supported by a metal plate 30 and a reflector 60 that reflects the light emitted from the light-emitting unit 40 toward the front of the luminaire.

[0031] The light-emitting unit 40 comprises a light-emitting element 42 and a substrate 44 that supports the light-emitting element 42. The light-emitting element 42 is a white light-emitting diode and has a horizontally elongated rectangular light-emitting surface. The substrate 44 has a roughly rectangular outer shape that is long in the front-to-back direction of the lamp and is arranged to extend along the horizontal plane. The light-emitting element 42 is mounted on the lower surface of the substrate 44 at a position closer to the front of the lamp than the center of the substrate 44, with its light-emitting surface facing directly downwards.

[0032] As shown in Figure 2, a connector 46 is mounted on the rear end region of the lower surface of the substrate 44, which is electrically connected to the light-emitting element 42 via a conductive pattern 48. This connector 46 is positioned directly behind the light-emitting element 42 and has an opening facing the rear of the lamp. A power supply connector 70 is connected to this connector 46 from the rear of the lamp.

[0033] The reflector 60 is located below the light-emitting unit 40. The reflective surface 60a of the reflector 60 is composed of a plurality of reflective elements 60s arranged in a vertical and horizontal grid pattern. Each reflective element 60s is formed in a concave curved shape with the paraboloid of revolution, with the light-emitting center of the light-emitting element 42 as its focal point, as its reference plane.

[0034] The three lighting units 20A to 20C are configured to form a low-beam light distribution pattern by controlling the reflection of light from the light-emitting element 42 at each reflective element 60s that constitutes the reflective surface 60a of the reflector 60.

[0035] The reflector 60 includes a horizontal plate portion 62 formed to extend along a horizontal plane at the upper end of its reflective surface 60a. This horizontal plate portion 62 has an opening 62a formed therein to allow light from the light-emitting element 42 to illuminate the reflective surface 60a of the reflector 60. The light-emitting unit 40 has its substrate 44 sandwiched from both the upper and lower sides by the horizontal plate portion 62 and the metal plate 30.

[0036] As shown in Figure 1, the reflectors 60 constituting each of the three luminaire units 20A to 20C are integrally formed as a reflector assembly 50. This reflector assembly 50 is a resin molded product, and the reflectors 60 of the three luminaire units 20A to 20C are continuously formed in a state where they are connected at their horizontal plate portion 62. As a result, the three luminaire units 20A to 20C are also configured as a single structure and are supported by the lamp body 12 so as to be rotatable in the vertical and horizontal directions via an aiming mechanism (not shown).

[0037] Each of the three luminaire units 20A to 20C comprises a reflector 60, which is equipped with an upward-facing flange portion 64 formed to bend upward along the front and left-side edges of its horizontal plate portion 62. This upward-facing flange portion 64 is formed to extend continuously along the entire length of the reflector assembly 50, thereby ensuring sufficient rigidity required for the reflector assembly 50.

[0038] Figure 3 is a detailed view of part III of Figure 1. Figure 4 is a perspective view showing the main part of the vehicle lighting fixture 10 as seen from diagonally above and behind the fixture.

[0039] As shown in Figures 3 and 4, the metal plate 30 is an aluminum plate of constant thickness and comprises a main body portion 32 extending along a horizontal plane and a vertical wall portion 34 formed to bend vertically downward from the main body portion 32. In this case, the main body portion 32 has an external shape in which the front-to-back width is greater than the left-to-right width, and the vertical wall portion 34 has an external shape in which the up-to-down width is greater than the left-to-right width.

[0040] As shown in Figure 3, the light-emitting unit 40 is positioned on the main body portion 32 of the metal plate 30 towards the rear of the lamp and towards the outside in the vehicle width direction.

[0041] A notch 34a is formed on the outer end face 34d in the vehicle width direction of the vertical wall portion 34 of the metal plate 30 to avoid interference with the power supply connector 70 attached to the connector 46 of the light-emitting unit 40. This notch 34a has a horizontally elongated rectangular shape when viewed from the rear of the lamp. This notch 34a is formed over a range from the upper region of the vertical wall portion 34 to the rear end face of the main body portion 32. That is, an extension portion 32a is formed on the main body portion 32 of the metal plate 30, extending from its inner region in the vehicle width direction toward the rear of the lamp, and the base end portion 34b of the vertical wall portion 34 is connected to this extension portion 32a.

[0042] The power supply connector 70 is provided, for example, on a harness extending from a control circuit (not shown) that controls the on / off switching of the light-emitting unit 40, and is configured to supply power to the light-emitting unit 40 when it is attached to the connector 46 of the light-emitting unit 40.

[0043] The main body portion 32 of the metal plate 30 is formed such that the front region of its outer end face 32d in the vehicle width direction tapers toward its tip surface (i.e., the front end surface of the main body portion 32). Furthermore, the vertical wall portion 34 of the metal plate 30 is formed such that the lower region of its inner end face 34c in the vehicle width direction tapers toward its tip surface (i.e., the lower end surface of the vertical wall portion 34).

[0044] As shown in Figure 3, the substrate 44 of the light-emitting unit 40 has a pair of positioning holes 44a on the left and right sides, located between the light-emitting element 42 and the connector 46. One of these pair of positioning holes 44a has a circular opening, while the other has a horizontally elongated oval opening.

[0045] In the rear region of the horizontal plate portion 62 of the reflector 60, a pair of left and right positioning pins 62b extending upward are formed at positions corresponding to the left and right positioning holes 44a of the substrate 44. In addition, in the region of the main body portion 32 of the metal plate 30 closer to the rear of the lamp, a pair of left and right pin insertion holes 32b are formed at positions corresponding to the left and right positioning holes 44a of the substrate 44. These left and right pairs of pin insertion holes 32b have an elongated oval opening shape.

[0046] Then, a pair of left and right positioning pins 62b in the reflector 60 are inserted from below into a pair of left and right pin insertion holes 32b in the substrate 44 and a pair of left and right positioning holes 44a in the metal plate 30, so that the light-emitting unit 40 is positioned in the horizontal plane, and its substrate 44 is sandwiched from both above and below by the metal plate 30 and the horizontal plate portion 62 of the reflector 60.

[0047] The metal plate 30 is fixed to the reflector 60 at three points on its main body 32. Specifically, the metal plate 30 is fixed to the horizontal plate portion 62 of the reflector 60 by heat scribing at two points on the left and right of the front region of the main body 32 and at one point on the rear of the inner region in the vehicle width direction.

[0048] Specifically, the horizontal plate portion 62 of the reflector 60 has three crimping pins 62c extending upward, arranged in a roughly L-shape around the substrate 44 of the light-emitting unit 40. The main body portion 32 of the metal plate 30 has three pin insertion holes 32c formed at positions corresponding to the three crimping pins 62c for insertion. Furthermore, the horizontal plate portion 62 of the reflector 60 has annular mounting portions 62d that cylindrically surround each of the three crimping pins 62c. These three annular mounting portions 62d are formed to the same height as the thickness of the substrate 44. As a result, when the main body portion 32 of the metal plate 30 is heat-crimped to the horizontal plate portion 62 of the reflector 60, the main body portion 32, which is placed on the three annular mounting portions 62d, maintains a horizontal position and makes surface contact with the substrate 44.

[0049] As shown in Figure 4, the reflector assembly 50 is formed such that a portion of the horizontal plate portion 62 of the reflector 60 of the three lighting units 20A to 20C fits into the notch portion 34a of the metal plate 30, in order to ensure sufficient rigidity.

[0050] Next, the effects and advantages of this embodiment will be described.

[0051] In this embodiment, the vehicle lamp 10 houses three lamp units 20A, 20B, and 20C arranged in a lamp chamber formed by a lamp body 12 and a light-transmitting cover 14, with the lamps positioned in a line in the vehicle width direction and sequentially displaced towards the rear of the lamp outward in the vehicle width direction. Each of these units comprises a light-emitting unit 40 and a reflector 60 supported by a metal plate 30. The metal plate 30 has a main body portion 32 and a vertical wall portion 34 formed to bend downward from the main body portion 32, thereby improving its heat dissipation performance.

[0052] Furthermore, since a notch 34a is formed on the outer end face 34d of the vertical wall portion 34 of the metal plate 30 to avoid interference with the power supply connector 70, even though the width of the metal plate 30 is narrowed due to the arrangement of the three lamp units 20A to 20C being sequentially displaced towards the rear of the lamps toward the outside in the vehicle width direction, it is possible to secure wiring space for the power supply connector 70.

[0053] Thus, according to this embodiment, in a vehicle lamp 10 in which three lamp units 20A to 20C are housed in a lamp chamber formed by a lamp body 12 and a light-transmitting cover 14, even if the three lamp units 20A to 20C are arranged to be sequentially displaced toward the rear of the lamp toward the outside in the vehicle width direction, it is possible to secure heat dissipation performance and wiring space for the power supply connector 70 for each of them.

[0054] In particular, as in the vehicle lighting fixture 10 according to this embodiment, when the spacing between the three lighting units 20A to 20C is set such that the spacing in the front-to-rear direction of the lighting fixtures is greater than the spacing in the vehicle width direction, it becomes even more difficult to secure sufficient width for the metal plate 30 in each of the three lighting units 20A to 20C. Consequently, it also becomes even more difficult to secure wiring space for the power supply connector 70. Therefore, adopting the configuration of this embodiment is particularly effective.

[0055] Furthermore, in this embodiment, the metal plate 30 is fixed to the reflector 60 at three locations on its main body 32. Since these three locations are set at two locations on the left and right of the front region of the main body 32 and one location at the rear of the inner region in the vehicle width direction, the metal plate 30 can be stably fixed in a limited space. Moreover, the one location at the rear of the inner region in the vehicle width direction of the main body 32 is located at the point where it connects to the base end 34b of the vertical wall 34, which has a notch 34a formed on its outer end face 34d in the vehicle width direction, so sufficient support rigidity for the vertical wall 34 can be ensured.

[0056] Furthermore, in this embodiment, the metal plate 30 is secured to the reflector 60 at the three locations mentioned above by heat crimping, so that the metal plate 30 can be securely fixed without increasing the number of lamp components.

[0057] Furthermore, in this embodiment, the main body portion 32 of the metal plate 30 is formed such that the outer end face 32d in the vehicle width direction tapers toward the front end face. This makes it easy to secure the required distance between the metal plate 30 and the light-transmitting cover 14, even though the three lamp units 20A to 20C are arranged to be sequentially displaced toward the rear of the lamp in the vehicle width direction. This prevents the three lamp units 20A to 20C from unintentionally interfering with the light-transmitting cover 14 when they are rotated relative to the lamp body 12 for optical axis adjustment.

[0058] Furthermore, since the vertical wall portion 34 of the metal plate 30 is formed such that its inner end face 34c in the vehicle width direction tapers toward the front end, it becomes easy to secure the required distance between the metal plate 30 and the lamp body 12.

[0059] Furthermore, in this embodiment, since the reflectors 60 that constitute each of the three lighting units 20A to 20C are made as a single molded product, the metal plates 30 of each of the three lighting units 20A to 20C can be supported by a common reflector assembly 50, thereby making it easy to secure space for arranging the metal plates 30.

[0060] Furthermore, since a notch 34a is formed on the outer end face 34d of the metal plate 30 on the vehicle width direction in each of the three lighting units 20A to 20C, it is possible to position the horizontal plate portion 62 of the reflector 60 of each of the three lighting units 20A to 20C such that a part of it fits into the notch 34a of the metal plate 30, thereby increasing the rigidity of the reflector assembly 50.

[0061] In the above embodiment, the notch 34a of the metal plate 30 was described as having a horizontally elongated rectangular notch shape when viewed from the rear of the lamp, but it is also possible to have a configuration with a notch shape other than this.

[0062] In the above embodiment, the metal plate 30 was described as being formed such that the vertical wall portion 34 bends vertically downward from the rear end position of the main body portion 32 which is formed to extend along the horizontal plane. However, it is also possible to have a configuration in which it bends diagonally downward instead of vertically downward.

[0063] In the above embodiment, the vehicle lighting fixture 10 was described as having three lighting units 20A to 20C, but it is also possible to have a configuration with two or four or more lighting units.

[0064] In the above embodiment, the vehicle lighting device 10 was described as being configured as a headlamp for low-beam illumination, but it is also possible to configure it as a lighting device having other light distribution functions.

[0065] Next, a modified example of the above embodiment will be described.

[0066] Figure 5 is a diagram similar to Figure 2, showing a vehicle lighting device 110 according to this modified example.

[0067] As shown in Figure 5, the basic configuration of this modified example is the same as that of the above embodiment. However, in this modified example, the reflector 160 is positioned above the light-emitting unit 40 as the luminaire unit 120B. Consequently, the light-emitting unit 40 and the metal plate 130 are positioned upside down compared to the configuration of the above embodiment, and the shape of the metal plate 130 is slightly different from that of the above embodiment.

[0068] The vehicle lamp 110 according to this modified example is also configured as a headlamp for low-beam illumination, and has a configuration in which three lamp units, including lamp unit 120B, are housed in a lamp chamber formed by a lamp body 112 and a translucent cover 114. In this modified example, the lamp body 112 is formed such that the upper region of the rear wall 112a extends inclined toward the front of the lamp. The other two lamp units (not shown) have the same configuration as lamp unit 120B.

[0069] The reflector 160 in this modified example is basically the same as the reflector 60 of the above embodiment but inverted vertically. However, the surface shape of the multiple reflective elements 160s that make up the reflective surface 160a is different from that of the above embodiment.

[0070] Furthermore, in this modified example, the reflector 160 has a configuration in which a horizontal plate portion 162 is formed at the lower end of its reflective surface 160a, and an opening 162a is formed in this horizontal plate portion 162. A downward-facing flange portion 164 is formed in this horizontal plate portion 162, which extends downward along its front edge and left edge.

[0071] In this modified example, the metal plate 130 is positioned upside down compared to the above embodiment, so the vertical wall portion 134 is formed to bend upward from the main body portion 132. In this case, the vertical wall portion 134 is formed to curve upward toward the front of the light fixture.

[0072] In this modified example, the metal plate 130 also has a notch 134a formed on the outer end face 34d in the vehicle width direction in the lower region of its vertical wall portion 134 to avoid interference with the power supply connector 70.

[0073] Even when adopting the configuration of this modified example, the same effects and advantages as in the above embodiment can be obtained.

[0074] Furthermore, in this modified example, the lamp body 112 is formed such that the upper region of the rear wall 112a extends inclined toward the front of the lamp. However, in this modified example, the metal plate 130 is formed such that the vertical wall portion 134 extends upward from the main body portion 132 in a curved manner toward the front of the lamp, thus preventing interference with the rear wall 112a of the lamp body 112.

[0075] It should be noted that the numerical values ​​shown as specifications in the above embodiments and their modified forms are merely examples, and these may be set to different values ​​as appropriate.

[0076] Furthermore, the present invention is not limited to the configurations described in the above embodiments and their modifications, and various other modified configurations can be adopted. [Explanation of Symbols]
