[0005] Patent Document 1: Japanese Patent No. 6736978 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] In the vehicle lamp described in Patent Document 1, the heat sink protrudes rearward from the base in the first light source unit, and the heat sink protrudes downward from the base in the second light source unit. Therefore, when an air supply mechanism for promoting heat dissipation is provided, it can only be positioned so that the airflow is appropriate relative to both the rearward-protruding heat sink and the downward-protruding heat sink, and the degree of freedom in setting the air supply mechanism is extremely limited.

[0008] This invention was made to solve such previous problems, and its purpose is to provide a vehicle lamp that can increase the degree of freedom in setting the air supply mechanism.

[0020] The following describes vehicle lighting fixtures according to embodiments of the present disclosure. However, the present invention is not limited to these embodiments, and appropriate modifications can be made without departing from the spirit of the invention. Furthermore, in the embodiments, some parts of the structure are omitted from the illustrations and descriptions; however, regarding the details of the omitted technology, well-known or publicly known techniques are appropriately applied without contradicting the following description.

[0021] Figure 1 This is a front view showing the vehicle lighting fixture according to this embodiment. Figure 2 It means Figure 1 A frontal perspective view of a portion of the structure. Additionally, in Figure 1 In the diagram, for ease of understanding, the settings are omitted. Figure 1 The structure shown includes the front external lens and frame.

[0022] Figure 1 The vehicle lamp 1 shown is, for example, a headlight located at the right front of a vehicle, comprising a first unit 10, a second unit 20, and a projection lens 2 positioned in front of them. The vehicle lamp 1 has a structure in which the first unit 10 and the second unit 20 are arranged sideways. The projection lens 2 receives the first light source (reference numeral 11) from the first unit 10 and the second light source (reference numeral 21) from the second unit 20 and emits light in a manner that forms a predetermined light path.

[0023] like Figure 2 As shown, the first unit 10 is a lighting unit for forming a so-called high beam distribution, comprising a circuit board CB1 on which a first light source 11 is mounted, a lens 12, and a first base member 13. The first light source 11 emits light forward (in a first direction) towards the vehicle. The first light source 11 is mounted on the circuit board CB1, which controls the emission of the first light source 11. The circuit board CB1 is mounted on the first base member 13. The lens 12 is an optical lens for high beams disposed in front of the first light source 11, and is fixed to the first base member 13 via the circuit board CB1 using threaded components or the like. The first base member 13 is a metal plate for mounting the first light source 11. The first base member 13 is positioned so that the normal direction of the plate faces forward.

[0024] The normal direction of the first base component 13 of the first unit 10 is forward, and the first light source 11 is mounted on the first base component 13 via the circuit board CB1. Therefore, the first unit 10 is configured as a direct-projection lamp that projects light from the first light source 11 toward the front of the vehicle via the lens 12.

[0025] The second unit 20 is a lighting unit for forming a so-called low beam distribution, comprising a circuit board CB2 on which a second light source 21 is mounted, a reflector 22, a lampshade 23, and a second base member 24. The second light source 21 emits light upwards towards the vehicle (in a second direction intersecting the first direction). The second light source 21 is mounted on the circuit board CB2, which controls the emission of the second light source 21. The circuit board CB2 is mounted on the second base member 24. The reflector 22 has a reflective surface on its inner side, based on a rotating elliptical surface, covering the top of the second light source 21, with the open side of the rotating elliptical surface facing forward of the vehicle. The lampshade 23 forms a light and dark cut-off line for low beam using a cut-off portion 23a, which cuts off a portion of the light emitted from the second light source 21 and reflected by the reflector 22. The lampshade 23 is provided to protrude upwards from the front end of the second base member 24. The second base member 24 is a metal plate for mounting the second light source 21. The second base member 24 is provided with the normal direction of the plate pointing upwards.

[0026] The normal direction of the second base component 24 of this second unit 20 is upward, and the second light source 21 is mounted on the second base component 24 via the circuit board CB2. Furthermore, the second unit 20 is arranged such that the reflector 22 covers the top of the second light source 21, and the open side of the rotating elliptical surface faces the front of the vehicle. Therefore, the second unit 20 is configured as a projection-type lamp that projects light from the second light source 21 toward the front of the vehicle via the reflector 22.

[0027] Figure 3 It means Figure 2 A frontal 3D view of part of the structure. Figure 4 It means Figure 2 A rear 3D view of a portion of the structure. Additionally, Figure 5 yes Figure 2 Sectional view IV-IV.

[0028] Figure 3 as well as Figure 4 The first base component 13 and the second base component 24 shown are continuous and integral. Additionally, as... Figures 3-5 As shown, the first unit 10 (refer to) Figure 1 It also has a first heat sink 14.

[0029] The first heat sink 14 is a plurality of metal plates integrally formed with the first base component 13. The first heat sink 14 extends rearward (to the side opposite to the first direction) from the first base component 13. It should be noted that the first heat sink 14 is formed by extending laterally (specifically parallel to the second base component 24) in the direction in which the first unit 10 and the second unit 20 are arranged, but it is not limited to this and may also have an angle relative to the side.

[0030] And, as Figure 4 as well as Figure 5 As shown, Unit 20 (refer to) Figure 1 The device includes a third base component 25 and a second heat sink 26. The third base component 25 is a plate integrally connected to the second base component 24 and extending from the second base component 24 along the extending direction (vertical direction) of the first base component 13. Furthermore, the third base component 25 is not limited to extending parallel to the extending direction of the first base component 13, but may also have some angle relative to parallel (e.g., within about 20°).

[0031] The second heat sink 26 is a plurality of metal plates integrally formed with the third base component 25. The second heat sink 26 extends rearward from the third base component 25 in the same direction as the first heat sink 14. Like the first heat sink 14, the second heat sink 26 extends laterally (specifically parallel to the second base component 24) in the direction in which the first unit 10 and the second unit 20 are arranged. However, the second heat sink 26 is not limited to this and may also have an angle relative to the side.

[0032] Thus, the vehicle lamp 1 of this embodiment has direct-projection and projection-type units 10 and 20, and the first light source 11 and the second light source 21 emit light in different directions. Therefore, the normal directions of the first base member 13 and the second base member 24 that mount these light sources 11 and 21 are also different. Therefore, the extension directions of the heat sinks of lamps that simply form heat sinks on these base members 13 and 24 are different. However, the vehicle lamp 1 of this embodiment (refer to...) Figure 1 The system includes a third base member 25 extending from the second base member 24 of the second unit 20 in the same direction as the first base member 13, thus enabling the second heat sink 26 to extend from the third base member 25. As a result, the vehicle lamp 1 can have the first heat sink 14 extending from the first base member 13 and the second heat sink 26 extending from the third base member 25 in the same direction.

[0033] Here, as Figure 5 As shown, the third base component 25 is positioned in the normal direction from the second light source 21 toward the second base component 24. Therefore, the third base component 25 is positioned, for example, directly below the second light source 21. This allows the vehicle lamp 1 to suppress reduced heat dissipation due to the presence of the third base component 25 sandwiched between the second base component 24 and the second heat sink 26. Furthermore, in Figure 5In the example shown, the third base component 25 is configured to be aligned with the normal direction of the second light source 21, but it is not limited to this. The connection part C between the second base component 24 and the third base component 25 can also be positioned at the normal direction of the second light source 21.

[0034] Moreover, such as Figure 4 As shown, the first heat sink 14 and the second heat sink 26 are preferably multiple pieces (at least one or more) continuously integrated into one unit. Thus, for example, the heat dissipation paths between each heat sink 14, 26 are continuous. Here, if the heat dissipation path between the first heat sink 14 and the second heat sink 26 is interrupted, heat can easily accumulate in the interrupted portion, potentially leading to reduced heat dissipation performance. However, in the vehicle lamp 1 according to this embodiment, at least one of the first heat sink 14 and the second heat sink 26 is continuously integrated, thus at least one heat dissipation path is continuous. Therefore, the vehicle lamp 1 has a heat sink structure that helps reduce the possibility of heat accumulation.

[0035] In addition, such as Figure 3 as well as Figure 5 As shown, the second unit 20 includes multiple metal plates, i.e., third heat sinks 27, integrally formed with the third base component 25. Here, the third heat sinks 27 extend forward rather than backward of the third base component 25. Figure 3 As shown, in this embodiment, the second light source 21 is located further back than the first light source 11. Additionally, as... Figure 5 As shown, a third base component 25 is provided directly below the second light source 21. Due to this structure, the third base component 25 is also positioned slightly behind, with space in front of it. The third heat sink 27 extends forward of the third base component 25 using this space. Furthermore, in this embodiment, the third heat sink 27 is configured such that its heat dissipation path is vertical. That is, the heat dissipation path of the third heat sink 27 intersects (orthogonally) the heat dissipation path of the second heat sink 26.

[0036] Refer again Figure 2 The vehicle lamp 1 of this embodiment also includes a fan (air supply mechanism) 30 and a bracket 40. Figure 6 It means Figure 2 The three-dimensional view of the fan 30 and bracket 40 shown. Figure 7 yes Figure 2 The VI-VI section view. Furthermore, the VI-VI section is parallel to the first heat sink 14 and the second heat sink 26.

[0037] Figure 6 and Figure 7The fan 30 shown delivers air to the first heat sink 14 (first base component 13) and the second heat sink 26 (third base component 25). The fan 30 is positioned rearward relative to the first heat sink 14 and delivers air forward.

[0038] The bracket 40 is located between the fan 30 and the first heat sink 14 and the second heat sink 26. The bracket 40 has a first guide portion (guide portion) 41 that guides the airflow from the fan 30 to the first heat sink 14 and a second guide portion (guide portion) 42 that guides the airflow from the fan 30 to the second heat sink 26, and guides the airflow to each heat sink 14, 26.

[0039] like Figure 6 as well as Figure 7 As shown, the first guide portion 41 is formed by an opening in the bracket 40 located on the side closest to the fan 30. This first guide portion 41 is a generally semi-circular opening. The first guide portion 41 has a side 41a facing the opening and another side 41b. The front end of the side 41a slopes towards the other side. Conversely, the front end of the other side 41b also slopes slightly towards the other side, but its slope angle is smaller than that of the side 41a. Due to this structure, the opening area at the outlet of the first guide portion 41 is smaller than the opening area at the inlet. Furthermore, the opening inlet and outlet are approximately parallel (e.g., the difference in their planar angles is within 20°). Therefore, the airflow from the fan 30 is supplied to the first heat sink 14 with increased velocity through the first guide portion 41.

[0040] The second guide section 42 is formed by an opening in the bracket 40 located on the side opposite to the fan 30. The inlet side of the opening in the second guide section 42 is approximately semi-circular, and the outlet side is rectangular. The second guide section 42 has a side surface 42a facing the opening. The front side of the side surface 42a is inclined significantly to the other side. Therefore, airflow from the fan 30 is supplied to the second heat sink 26 through the second guide section 42. In addition, the second guide section 42 has a flat plate 43 opposite to the side surface 42a. Here, regarding the second guide section 42, the area of ​​the opening outlet is also smaller than the area of ​​the opening inlet. Therefore, the airflow from the fan 30 is also supplied to the second heat sink 26 with increased flow velocity through the second guide section 42. Furthermore, the opening inlet and opening outlet of the first guide section 41 are approximately parallel, making it easier to increase the flow velocity. On the other hand, the opening inlet and opening outlet of the second guide section 42 are not approximately parallel, so the effect of increasing the flow velocity may be smaller compared to the first guide section 41. However, the second guide section 42 can also increase the flow rate.

[0041] Here, as Figure 7As shown in the cross-sectional view, the third base component 25 is constructed with its surface 13a inclined relative to the mounting side of the first light source 11 in the first base component 13. The inclination direction is along the airflow direction toward the second heat sink 26. That is, compared to surface 13a, the side of the third base component 25 that is farther away from the fan 30 is inclined in a direction further away from the fan 30.

[0042] In addition, such as Figure 7 As shown in the cross-sectional view, the first base component 13 has an inclined portion 13b on the side of the second base component 24 (the other side). The inclined portion 13b guides the airflow from the fan 30 toward the first heat sink 14 to reach the first heat sink 14, and the airflow after reaching the first heat sink 14 is directed in the opposite direction to the side of the second heat sink 26. The inclined portion 13b is formed by making the rear portion of the first base component 13 a thick wall.

[0043] To explain in more detail: First, an airflow A1 flows parallel to one side 41a of the first guide section 41. The angle formed by the airflow A1 of the vehicle lamp 1 and the inclined section 13b (the angle formed on one side) is 90° or more. Furthermore, an airflow A2 flows parallel to the other side 41b of the first guide section 41. The angle formed by the airflow A2 of the vehicle lamp 1 and the inclined section 13b (the angle formed on one side) is 90° or more. Therefore, the airflow guided by the first guide section 41 bounces back to one side (the side opposite to the second heat sink 26) due to the angle setting of the inclined section 13b. As a result, the vehicle lamp 1 can reduce the possibility of airflow flowing towards and stagnating towards the second heat sink 26.

[0044] Next, the function of the vehicle lamp 1 in this embodiment will be explained. First, the vehicle lamp 1 has a third base member 25 disposed relative to the second base member 24, and this third base member 25 is disposed along the extending direction of the first base member 13. Therefore, the vehicle lamp 1 can be configured such that the first heat sink 14 disposed on the first base member 13 and the second heat sink 26 disposed on the third base member 25 extend in the same direction. As a result, the vehicle lamp 1 can make the placement position of the fan 30 less restricted by the different extending directions of the heat sinks.

[0045] In particular, since the vehicle lamp 1 extends the heat sinks 14 and 26 of both sides in the same direction, it can make at least one of the heat sinks 14 and 26 of both sides into a continuous structure, and can also make the heat dissipation path continuous.

[0046] Furthermore, the third base component 25 is positioned directly below the second base component 24, facing the second light source 21 along its normal direction. Therefore, the vehicle lamp 1 can quickly transfer heat from the second light source 21 to the third base component 25 and dissipate it from the second heat sink 26.

[0047] Furthermore, since the second light source 21 is positioned further rearward than the first light source 11, the third base component 25, which is positioned directly below the second light source 21, is also located slightly rearward. Therefore, the vehicle lamp 1 can have a third heat sink 27 positioned in front of the third base component 25.

[0048] Furthermore, the vehicle lamp 1 includes a bracket 40 with a first guide portion 41 and a second guide portion 42 between the fan 30 and the first heat sink 14 and the second heat sink 26. Therefore, the vehicle lamp 1 can guide the airflow from the fan 30 using the first guide portion 41 and the second guide portion 42, and the installation position of the fan 30 is not easily restricted, thus increasing the freedom of installation of the fan 30.

[0049] In addition, the outlet area of ​​the first guide section 41 and the second guide section 42 is smaller than the inlet area of ​​the opening, thereby increasing the airflow velocity toward the first heat sink 14 and the second heat sink 26.

[0050] Here, the first base component 13 has an inclined portion 13b on its rear side. The inclined portion 13b is set to direct the airflow arriving via the first guide portion 41 at an angle opposite to that of the second heat sink 26. Therefore, the airflow guided to the first heat sink 14 via the first guide portion 41 flows smoothly in the opposite direction to the second heat sink 26 after reaching the first base component 13.

[0051] On the other hand, the third base component 25 is inclined relative to the surface 13a of the mounting side of the first light source 11 of the first base component 13. Compared with surface 13a, the side of the third base component 25 away from the fan 30 becomes the direction away from the fan 30. Therefore, although the airflow guided to the second heat sink 26 by the second guide 42 is bounced back by the third base component 25, the amount of bounce is reduced. As a result, the vehicle lamp 1 reduces the possibility that the airflow from the fan 30 cannot reach the inner side of the third base component 25 by utilizing the airflow bounced back from the side near the third base component 25.

[0052] Thus, according to the vehicle lamp 1 of this embodiment, the second unit 20 includes a third base member 25 extending from the second base member 24 along the extending direction of the first base member 13. Therefore, by providing heat sinks 14 and 26 on the first base member 13 and the third base member 25, the vehicle lamp 1 can ensure that the heat sinks 14 and 26 on both sides extend in the same direction. As a result, the vehicle lamp 1 can alleviate the constraint on the installation position of the fan 30 caused by the different extending directions of the heat sinks on both sides, and can improve the freedom of installation of the fan 30.

[0053] Furthermore, since the third base component 25 is positioned from the second light source 21 toward the normal direction of the second base component 24, the heat generated by the second light source 21 is transferred to the third base component 25 and dissipated in advance through the second base component 24. Therefore, the vehicle lamp 1 can help improve heat dissipation.

[0054] Furthermore, since the first heat sink 14 and the second heat sink 26 are continuous and integrated, the heat dissipation path of the first heat sink 14 is directly continuous with the heat dissipation path of the second heat sink 26. Therefore, the vehicle lamp 1 can suppress heat retention caused by interruption of the mutual heat dissipation paths.

[0055] Furthermore, since the second light source 21 is located further rearward than the first light source 11, the third base component 25 is also located further rearward than the first light source 11. Therefore, the vehicle lamp 1 has space in front of the third base component 25. Thus, the vehicle lamp 1 can, for example, have a third heat sink 27 further provided in front of the third base component 25.

[0056] Furthermore, the vehicle lamp 1 has a bracket 40 between the fan 30 and the heat sinks 14 and 26 on both sides. The bracket 40 has guide parts 41 and 42 for guiding the airflow of the fan 30 respectively. Therefore, the vehicle lamp 1 can distribute the airflow from the fan 30 through the guide parts 41 and 42 respectively, and the installation position of the fan 30 is not easily restricted, which can improve the degree of freedom of the fan 30 installation.

[0057] Furthermore, the third base component 25 is inclined relative to the first base component 13, with the inclination direction further away from the fan 30. Therefore, the vehicle lamp 1 can reduce the amount of airflow from the fan 30 that bounces back upon contact with the third base component 25. This suppresses the possibility that airflow from the fan 30 might not reach the inner side of the third base component 25 due to airflow directed towards the side closest to the third base component 25. Therefore, the vehicle lamp 1 can contribute to improved heat dissipation performance.

[0058] In addition, the vehicle lamp 1 has an inclined portion 13b that guides the airflow after reaching the first heat sink 14 toward the side opposite to the side of the second heat sink 26, thereby reducing the possibility of the airflow being stagnant toward the side of the second heat sink 26.

[0059] In addition, the area of ​​the opening outlet of the bracket 40 is smaller than the area of ​​the opening inlet of the first guide 41 and the second guide 42, which can increase the airflow velocity and help improve heat dissipation.

[0060] The present invention has been described above based on the embodiments, but the present invention is not limited to the above embodiments. Modifications can be made and well-known technologies can be combined without departing from the spirit of the present invention.

[0061] For example, in this embodiment, the third base component 25 is disposed perpendicular to the second base component 24, but it is not particularly limited to being perpendicular, as long as it is along the extending direction of the first base component 13, and is not limited to being perpendicular.

[0062] In addition, the third base component 25 is located directly below the second light source 21, but is not particularly limited to that position and may be slightly offset.

[0063] In addition, such as Figure 5 As shown, the first heat sink 14 and the second heat sink 26 are integrated into the same plane, but are not particularly limited to the same plane. For example, the first heat sink 14 extends to the side, and the second heat sink 26 is integrated in a state that is slightly inclined relative to the side, and the two may not form the same plane.

[0064] Furthermore, the fan 30 is positioned behind the first heat sink 14, but is not particularly limited to this location. For example, the fan 30 may also be positioned behind the second heat sink 26 or in other locations, with the guide portions 41 and 42 of the bracket 40 directing airflow to each of the heat sinks 14 and 26. In addition, in this embodiment, the vehicle lamp 1 is positioned with the second light source 21 positioned further behind the first light source 11, leaving space behind the first light source 11 (i.e., behind the first heat sink 14). Therefore, it can be said that the fan 30 is preferably positioned behind the first heat sink 14.

[0065] Furthermore, the vehicle lamp 1 in this embodiment has been described using a headlight as an example, but it is not particularly limited to headlights.
