    [0001] TECHNICAL FIELD [0002] The present disclosure relates to a vehicle lamp. The present disclosure relates in particular to a vehicle lamp used for vehicles such as for example automobiles.
    [0002] BACKGROUND [0003] A vehicle lamp conventionally known in the related art has a substrate on which a light emitting diode (LED) is mounted as a light source, a heat dissipating plate disposed on a surface of the substrate on a face opposite to the mounting surface of the light source and a reflector disposed on the side of the mounting surface of the substrate light source (see for example, Japanese Patent Laid-open Publication No. 2015-046235).
    [0003] SUMMARY [0004] In the vehicle lamp having the structure described above, the substrate, the heat dissipating plate and the reflector are generally fixed to each other by fastening elements such as screws, for example. Through repeated extensive studies on a vehicle lamp, the inventors of this disclosure have come to understand that the amount of light of a vehicle lamp can be reduced due to the substrate attachment structure, heat and reflector in the conventional vehicle lamp. The present explanation has been made taking into account this situation and an objective of it is to provide a technology to increase the amount of light of a vehicle lamp. To solve the problem described above, one aspect of the present invention relates to a vehicle lamp. The vehicle lamp comprises a substrate having a light source mounting surface, a heat sink element disposed on a surface of the substrate on a face opposite to the mounting surface of the light source, a reflector disposed on the side of the light source, the mounting surface of the light source of the substrate for reflecting light emitted from a light source mounted on the mounting surface of the light source and a fixing member configured to fix the substrate therebetween, the element heat sink and reflector. The reflector has a boss portion that protrudes toward the side of the heat dissipating member and has a fixing hole for the fastener. The substrate has a first aperture in an area that covers the boss portion in the stacking direction of the reflector, substrate, and heat sink element. The heat sink element is in contact with the substrate to be thermally conductive with the substrate and has a first portion including a second opening in an area that covers the boss portion in the stack direction, a second portion that covers the second aperture in the direction of the stack and further spaced from the reflector than the first portion to include an insertion hole for the fastener and a fastening seat surface, and a connecting portion which connects between they the first part and the second part. The boss portion passes through the first opening and the second opening and abuts with the second portion, so that the attachment hole and the insertion hole are superimposed with each other in the direction of the stack.
    [0004] According to this aspect, the amount of light of a vehicle lamp can be increased. [0007] According to the aspect described above, the heat dissipating element may include a small width portion having a relatively small width and a large width portion having a relatively large width in an end zone. from the connecting portion that is in contact with the first portion to the insertion hole of the second portion. As a result, the stress generated by fixing the fastener can be absorbed by the small width portion. [0008] According to the present disclosure, the amount of light of a vehicle lamp can be increased. The above summary is only explanatory and is not intended in any way to be limiting. In addition to the aspects, embodiments and explanatory features described above, other aspects, embodiments and features will become apparent with reference to the drawings and the following detailed description.

All features described in the exemplary embodiments or combinations thereof may not be essential for this disclosure. In addition, for example, the terms "first" and "second" herein used or the claims are not intended to refer to any order of importance, but are intended to distinguish a component from another component. FIG. 1 is a sectional view schematically illustrating the structure of a headlight device including a vehicle lamp according to an exemplary embodiment. Fig. 2 is a view for describing a mounting structure of the vehicle lamp 5 of the exemplary embodiment. In addition, the scale or shape of each component illustrated in each of the drawings is set to facilitate its description and should not be construed as being limited. A lamp unit 100 as a vehicle lamp according to an exemplary embodiment is mounted for example in a headlight device 10. The headlight device 10 comprises a pair of headlight units which are respectively arranged on the front left and right sides of a vehicle. The units of the pair of lighthead units have a substantially identical configuration with the exception that their structures have a bilateral symmetry with respect to each other.
    [0006] Thus, FIG. 1 illustrates a structure of a unit of the pair of headlight units as a headlight device 10. [0016] The headlamp device 10 comprises a lamp body 11 and a transparent outer cover 12 which covers a front opening of the lamp body 11. The lamp body 11 and the outer cover 12 form a lamp chamber 13. The lamp unit 100 as a vehicle lamp is received inside the lamp chamber. The lamp unit 100 is configured to illuminate at least one of, for example, a traffic light distribution pattern and a low beam light distribution pattern. The lamp unit 100 is supported on the lamp body 11 by a support 50. The support 50 is formed for example of a resin material. A first inclination member 55 and a second inclination member 57 are attached to the support 50. The first inclination member 55 includes a sighting screw (or set screw) 55a attached to the lamp body 11, a unit screw connection 55b provided in the support 50 of the first inclination member 55 and an adjusting unit 55c disposed outside the lamp body 11. An end side of the sighting screw 55a is inserted into the screw connecting unit 55b and its other end is connected to the adjusting unit 55c. The second inclination member 57 has a ball joint 57a attached to the lamp body 11, a socket 57b which holds the ball joint of the ball joint 57a and a hole 57c formed in the support 50 of the second inclination member. 57. The base 57b is inserted in the hole 57c. In the present exemplary embodiment, the sighting mechanism (or adjustment mechanism) is connected to the support 50. However, the exemplary embodiment is not particularly limited to this configuration. The sighting mechanism can for example be directly connected to the lamp unit 100 without requiring the supports 50. When the aiming screw 55a is rotated through the adjustment unit 55c of the first inclination element 55, the support 50 is inclined with respect to the lamp body 11 around the ball of the ball joint 57a of the second inclination member 57 as a pivot. In this way, the optical axis of the lamp unit 100 can be adjusted. The lamp unit 100 comprises a substrate 110, a reflector 130, a heat dissipating element 150 and a fixing element 170. The lamp unit 100 of this exemplary embodiment is a so-called parabolic lamp unit. The substrate 110 is a substantially flat shaped member which supports a light source 114. The substrate 110 has a light source mounting surface 112 and the light source 114 is mounted on the mounting surface of the source The light source 114 is, for example, a light-emitting diode (LED). In the present exemplary embodiment, the main surface of the substrate 110 which is turned vertically downward is the mounting surface of the light source 112. The light source 114 is mounted on the mounting surface of the source of light. light 112 so that its light-emitting surface is turned vertically downward. The mounting surface of the light source 112 is provided with a wiring pattern (not shown) to which the light source 114 is electrically connected. In the present exemplary embodiment, the posture of the lamp unit 100 is fixed so that the light-emitting surface 30 of the light source 114 is turned vertically downwards. However, the posture of the lamp unit 100 is not limited to this configuration. The posture of the lamp unit 100 may for example be fixed so that the normal line of the light emitting surface of the light source 114 is parallel to the horizontal surface. For example, the lamp unit 100 may assume a posture in which it is rotated 90 degrees about the optical axis with respect to the state shown in Fig. 1, so that the light emitting surface of the light source 114 is turned towards the side of the lamp unit. Alternatively, the posture of the lamp unit 100 may be fixed so that the light emitting surface of the light source 114 is turned vertically upward. The installation angle of the lamp unit 100 may be appropriately selected. In addition, the substrate 100 has a first opening 116 in an area which covers a boss portion 136 which will be described later, in the stacking direction A of the reflector 130, 10 of the substrate 110 and the dissipating element. 150 (in the direction represented by the arrow A in Figures 1 and 2). The reflector 130 is disposed on the side of the light mounting surface 112 of the substrate 110. The reflector 130 has a flat plate-shaped base portion 132 which abuts with the substrate 110 and a reflective portion 134 which extends from the end of the base portion 132 of the rear side of the vehicle to the front side of the vehicle while being curved downwardly. The base portion 132 has a light source opening 132a in an area that overlies the light source 114. The reflective portion 134 has a reflective surface 134a that reflects light emitted from the light source 114 mounted on the surface of the light source. mounting the light source 112 to the front side of the lamp. The reflective surface 134a is shaped based for example on the shape of a rotary parabolic surface whose central axis of rotation is the optical axis of the reflector 130. The reflector 130 is arranged so that its axis optical extends in the front-rear direction of the vehicle. The light source 114 is disposed in the light source opening 132a, so that its light-emitting surface is substantially opposite to the reflecting surface 134a. The mutual positional relationship between the light source 114 and the reflecting surface 134a is fixed so that the focus of the reflecting surface 134a overlaps the light source 114. The reflector 130 also includes the boss portion 136. The boss portion 136 is disposed on the surface of the base portion 132 which is in contact with the substrate 110 and protrudes toward the side of the heat sink element 150. The boss portion 136 includes a hole The reflector 130 is formed by performing aluminum deposition on an area such as a resin molded substrate which corresponds at least to the reflective surface 134a. The heat dissipating element 150 is formed for example of an aluminum plate and has a heat dissipation function generated by the light source 114. By providing the heat sink element 150, the Heat dissipation performance from the light source 114 can be improved.
    [0007] The heat dissipating member 150 is disposed on the surface of the substrate 110 on the face opposite to the mounting surface of the light source 112. The heat dissipating member 150 includes a first portion 152, a second portion 154, and a connecting portion 156. [0026] The first portion 152 has a flat plate shape 15 and is in contact with the substrate 110 so as to be thermally conductive with the substrate 110. In the present exemplary embodiment, the first portion 152 Part 152 and the substrate 110 are in contact with each other via a heat transfer sheet 158 which has an insulating property and a certain flexibility or elasticity.
    [0008] The heat transfer sheet 158 is provided in an area which overlies at least the light source 114 in the direction of the stack A. The heat transfer sheet 158 is interposed between the substrate 110 and the first portion 152, so that the heat transfer between the substrate 110 and the heat sink element 150 can be more reliably ensured, thereby further improving the heat dissipation performance from the light source 114. The first part and the substrate 110 may be in direct contact with each other. Without being limited to the heat transfer sheet 158, a thermal interface material (TIM), such as for example a thermal conductive grease or a thermal conductive glue, may be interposed between the first portion 152 and the substrate 110. [ The first portion 152 includes a second opening 152a in an area that overlies the boss portion 136 in the direction of the stack A. [0028] The second portion 154 is disposed in a position that covers the second opening 152a in the direction of stack A.
    [0009] The second portion 154 is further away from the reflector 130 than the first portion 152. The second portion 154 has an insertion hole 154a for the fastener 170 and a fastening seat surface 154b disposed around the fastener hole. insertion 154a. The second portion 154 extends, for example, in parallel with the first portion 152. [0029] The connecting portion 156 connects the first portion 152 and the second portion 154 together. An end side of the connecting portion 156 is connected to the first portion 152. The connecting portion 156 then extends vertically upward or in a direction separate from the substrate 110 or reflector 130 relative to the first portion 152, so that the other face The end of the connecting portion 156 is connected to the second portion 154. [0030] The heat dissipating member 150 has a small width portion T having a relatively small width and a large width portion W having a relatively wide width. large, in an area from the end 156a of the connecting portion 156 which is in contact with the first portion 152 to the insertion hole 154a of the second portion 154. The width N of the portion of small width T is inferior ure to the width M of the part of great width W, and the width M of the part of great width W is greater than the width N of the part of small width T. The range of the area where the part of small The width T and the large width portion W are provided, for example, from the end 156a to the end of the insertion hole 154 which is closest to the connecting portion 156. In the present exemplary embodiment, the small width portion T is provided in the region from the end 156a of the connecting portion 156 to the middle of the connecting portion 156, and the remainder of the connecting portion 156 and the second portion 154 forming the width portion W. Here, the "width" of the small width portion T and the large width portion W refer to a dimension in the direction orthogonal to the extension direction of the element provided with the part of small width T or the part of great width W. In In the present exemplary embodiment, the width of the small width portion T refers to the length of the region of the connecting portion 156 where the small width portion T is provided, in the direction orthogonal to the direction d extension of the connecting portion 156. In addition, the width of the wide width portion W refers to the length of the zone 156b in the direction orthogonal to the extension direction of the connecting portion 156, and the length of the second portion 154 in the direction orthogonal to the direction of extension of the second portion 154. The extension direction of the connecting portion 156 refers to the direction in which, for example, is arranged the end 156a of the connecting portion 156 and its end which is in contact with the second portion 154. The extension direction of the second portion 154 refers to the direction in which, for example, the end of the second end is arranged. pa 154 which is in contact with the connecting portion 156 and the insertion hole 154a. In other words, the connecting portion 156 has a portion in which the opposite sides of the connecting portion 156 move away from each other by steps towards the end side of the portion of link 156 which is in contact with the second portion 154 with respect to the end side 156a. In the present exemplary embodiment, the opposite sides move away from each other other than by single pitch, but may move away from each other in multiple steps. In addition, the distance between opposite sides can increase continuously. In addition, the connecting portion 156 may comprise a portion in which the opposite sides of the connecting portion 156 approach each other in a stepwise or continuous manner toward the end side of the connecting portion 156 which is in contact with the second portion 154 with respect to the end side 156a. In this case, the small width portion T is provided in a position spaced from the end 156a. In addition, the area of the section of the part of small width T which is orthogonal to the direction of extension of the element provided with the part of small width T is smaller than the area of the cross-section. the part of large width W which is orthogonal to the direction of extension of the element provided with the part of great width W. In addition, the width N 30 of the part of small width T is for example narrower than the width of the area of the fixing seat surface 154b on which the head of the fastening element 170 is in contact. In addition, the part of small width T and the part of large width W can adopt various shapes and arrangements as well as described in the modifications 35 which will be described later. The heat dissipating member 150 may be formed by providing a notch along the shapes of the second portion 154 and the connecting portion 156 in a predetermined position, for example, of an aluminum plate. and cutting the inner part of the notch.
    [0010] The cut portion of the aluminum plate becomes the second portion 154 and the connecting portion 156 and the remainder thereof becomes the first portion 152. [0035] The fastener 170 is configured to secure between them the substrate 110, the heat sink element 150 and the reflector 130.
    [0011] The fastener 170 is for example a screw. As illustrated in FIG. 2, the substrate 110 and the heat sink element 150 are disposed on the base portion 132 of the reflector 130. In this case, the boss portion 136, the first aperture 116, and the second aperture 152a are positioned so as to be superimposed on each other in the direction of the stack A. The substrate 110 and the heat sink element 150 are then stacked on the base portion 132. [0036] Accordingly, as illustrated in FIG. 1, the boss portion 136 passes through the first opening 116 and the second opening 152a and abuts with the second portion 154, so that the fixing hole 136a and the insertion hole 154a are superimposed therebetween in the direction of the stack A. In this state, the fastener 170 is inserted into the insertion hole 154a and passes through it, so as to be fixed in the fixing hole 136a. When the fastener 170 is a screw, the fastener 170 is threadably coupled to the fastener hole 136a. The head of the fastener 170 abuts the attachment seat surface 154b. In this way, the substrate 110, the reflector 130 and the heat dissipating element 150 can be fixed together. As described above, the lamp unit 100 as a vehicle lamp according to the present exemplary embodiment 30 comprises the substrate 110, the reflector 130, the heat sink element 150 and the element. The reflector 130 includes the boss portion 136 that protrudes toward the side of the heat dissipating member 150 and has the attachment hole 136a. The substrate 110 has the first aperture 116 through which the boss portion 136. The heat dissipating member 150 includes the first portion 152 which includes the second opening 152a through which the boss portion 136 passes, the second portion 154 which is disposed on the upper face with respect to the first portion to include the insertion hole 154a and the attachment seat surface 154b and the connecting portion 156 which interconnects the first portion 152 and the second portion 154. The boss portion 136 projects toward the side of the heat sink element 150 so that its front end abuts with the second portion 154. In this state, the fastener 170 is inserted into the hole of the heat sink element 150. insertion 154a and the crossbar, so that the substrate 110, the reflector 130 and the heat sink element 150 are fixed together. In a conventional structure of securing a substrate, a heat dissipating element and a reflector together using a fastening element, a boss portion provided in the reflector protrudes towards the side of the reflector. the reflective surface. It is required of the boss portion to have a predetermined height to ensure the depth of the fastener hole in which the fastener member is engaged. Thus, in the conventional structure, the boss portion may cover the light path of the light emitted by a light source, in particular, the light path through which light reflected on the reflective surface is directed to the front side of the light. the lamp. In this case, the path of light to the front side of the lamp is obstructed by the boss portion, thereby decreasing the amount of light of the vehicle lamp. The superposition between the boss part and the light path of the light emitted by the light source can be avoided by spacing the substrate and the reflector from one another and arranging the boss portion of the way to protrude towards the side of the substrate, so that the boss portion is received in the space between the substrate and the reflector. However, when the substrate and the reflector are separated from each other, the solid angle of light flux incident on the reflective surface of the reflector from the light source is reduced. That is, light emitted by the light source, a certain amount of light that can reach the reflective surface of the reflector, is reduced. As a result, the amount of light from the vehicle lamp is reduced. In the present exemplary embodiment, the boss portion 136 protrudes toward the side of the substrate 110 and is inserted into the first opening 116 of the substrate 110 and the second opening 152a of the heat sink element. heat 150 and crosses them. Accordingly, since the space for receiving the boss portion 136 may not be provided between the substrate 110 and the reflector 130, the substrate 110 and the reflector 130 may be positioned close to each other. It is thus possible to avoid that the boss portion 136 and the light path of the light emitted by the light source are superimposed between them and also to avoid that the solid angle of the incident light flux is reduced. As a result, the amount of light of the vehicle lamp 10 can be increased. In addition, the heat dissipating element 150 comprises the part of small width T and the part of large width W in the range from the end 156a of the connecting portion 156 which is in contact with the first part. 152 to the insertion hole 154a of the second portion 154. Since the two zones having different widths are provided, the small width portion T having a relatively small width naturally becomes a fragile portion with respect to the large portion. width W having a relatively large width. Thus, the small width portion T is deformed by the stress generated when the fastener 170 is attached. As a result, the small width portion T is able to absorb the stress generated when the fastener 170 is attached. Further, since the stress can be absorbed by the small width portion T, it is possible to prevent the substrate 110 from being deformed by the stress generated at the time of its attachment thereby causing a positional deviation of the light source. 114. Accordingly, it is possible to eliminate the degradation in the accuracy of forming a light distribution pattern by the lamp unit 100. [0042] The present discussion is not limited to the example of the mode. embodiment described above. Other modifications (e.g., various design modifications) can be made to this disclosure based on the knowledge of a person skilled in the art. The scope of this discussion also includes examples of embodiments to which the modifications apply.

In this case also, the stress generated at the time of attachment of the fastening element 170 can be absorbed by the small width portions T. In addition, the small width portion T can be formed by providing an opening in the region from the end of the second portion 154 which contacts the connecting portion 156 to the insertion hole 154a. In addition, the opening 156c formed in the connecting portion 156 and the opening in the second portion 154 may be continuous with each other so as to become an opening.
