It gets bigger. Thereby, the conventional vehicle lamp has the first light source and the second light source provided with a step so that the second light source is positioned below the first light source.

  Hereinafter, Example 1 of the vehicular lamp 10 as an embodiment of the vehicular lamp according to the present disclosure will be described with reference to FIGS. 1 to 3.

  The vehicular lamp 10 is used as a lamp used in a vehicle such as an automobile, and is used for a headlamp, a fog lamp, and the like, for example. The vehicular lamp 10 has an optical axis adjustment mechanism for vertical direction and an optical axis adjustment for width direction in a lamp chamber formed on both the left and right sides of the front portion of the vehicle with the front end of the lamp housing being covered with an outer lens. It is provided via a mechanism. In the following description, in the vehicular lamp 10, the direction in which the vehicle travels straightly and irradiates light is the optical axis direction, and the vertical direction when mounted on the vehicle is the vertical direction. The direction perpendicular to the vertical direction is defined as the width direction.

  As shown in FIG. 1, the vehicular lamp 10 includes a first light source 11, a second light source 12, a heat sink member 13, a reflector 14, a shade 15, an auxiliary lens 16, and a projection lens 17, and a projector type headlamp. Configure the unit.

  The first light source 11 is composed of a light emitting element such as an LED (Light Emitting Diode), and is mounted on the substrate 20. The substrate 20 is fixed to the upper surface 13 a of the heat sink member 13. The first light source 11 is appropriately turned on when power is supplied from the lighting control circuit.

  The second light source 12 is composed of a light emitting element such as an LED, and is mounted on the substrate 21 on the front side in the optical axis direction (the side that emits light from the vehicular lamp 10) than the first light source 11. The substrate 21 is fixed to the upper surface 13 a of the heat sink member 13 on the front side in the optical axis direction from the substrate 20. For this reason, the second light source 12 is provided on the same plane as the first light source 11. The second light source 12 is appropriately lighted when power is supplied from the lighting control circuit. The second light source 12 of the first embodiment is provided with five light source portions 12a (only one on the front side is shown in FIG. 1) aligned in the width direction on the substrate 21. Each light source part 12a is comprised by a light emitting element, and is lighted simultaneously or individually suitably by supplying electric power from a lighting control circuit. In addition, what is necessary is just to set the number of the light source parts 12a suitably, and is not limited to the structure of Example 1. FIG.

  The heat sink member 13 is a heat radiating member that releases heat generated by the first light source 11 and the second light source 12 to the outside. In the heat sink member 13, the substrate 20 and the substrate 21 are provided on the upper surface 13a, and the reflector 14 is provided on the upper surface 13a so as to cover both the substrates (20, 21). In the heat sink member 13 of the first embodiment, the upper surface 13a on which the first light source 11 and the second light source 12 are provided via both substrates (20, 21) is below the optical center position of the projection lens 17 in the vertical direction. Is provided. Thereby, light with high intensity | strength among the lights radiate | emitted from the 1st light source 11 provided in the upper surface 13a can be utilized effectively.

  The reflector 14 is attached to the heat sink member 13 (upper surface 13a) so as to cover the substrate 20 and the substrate 21, that is, the first light source 11 and the second light source 12 mounted thereon. The reflector 14 has a reflecting surface 22 that faces the upper surface 13a. The reflection surface 22 is provided to reflect the light emitted from the first light source 11 to the projection lens 17. The reflecting surface 22 is a free curved surface based on an ellipse having the first light source 11 as a first focal point and a second focal point in the vicinity of a tip edge 15a, which will be described later, of the shade 15.

  The shade 15 is provided on the heat sink member 13 and has a plate shape extending in the width direction while being orthogonal to the vertical direction. The shade 15 of the first embodiment is formed such that the thickness in the vertical direction decreases as it goes toward the front side in the optical axis direction, and the front end edge 15a in the optical axis direction is pointed in a cross section orthogonal to the width direction ( Pointed). The tip edge 15a has a shape in which two horizontal edges having different positions in the optical axis direction are connected by an inclined edge. The shade 15 shields a part of the light emitted from the first light source 11 and reflected by the reflecting surface 22 of the reflector 14 with the tip edge 15a, so that two horizontal light distribution patterns LP, which will be described later, are arranged on the upper edge. A cut-off line Cl (see FIG. 2) is formed by connecting the lines with inclined lines.

  The shade 15 has a reflection surface 15b on the lower surface in the vertical direction. The reflecting surface 15b forms an auxiliary light distribution pattern AP, which will be described later, and reflects light incident on the auxiliary lens 16 from an incident surface 16a, which will be described later, to the projection lens 17 side. The reflection surface 15b is formed by subjecting the lower surface of the shade 15 to surface treatment. This surface treatment is to blur or mainly diffuse the auxiliary light distribution pattern AP to be formed, and to perform reflection while diffusing light. The surface treatment is not limited to the configuration of the first embodiment as long as the degree of diffusion and the reflectance are appropriately set according to the size, shape, brightness, and the like required for the auxiliary light distribution pattern AP to be formed.

  The auxiliary lens 16 collects a part of the light emitted from the second light source 12 and advances it to the front side in the optical axis direction, that is, the projection lens 17 side. The auxiliary lens 16 of Example 1 is formed of a colorless transparent resin material (transmission member) that allows light to pass therethrough. Here, the colorless and transparent material means that the light emitted from the second light source 12 (each light source unit 12a) is transmitted without being changed. In addition, the auxiliary lens 16 of Example 1 is provided as close to the shade 15 as possible in the vertical direction. The auxiliary lens 16 has a flat entrance surface 16a, a curved internal reflection surface 16b, and a flat exit surface 16c.

  The incident surface 16 a is provided so as to face the second light source 12 (each light source unit 12 a) in the vertical direction, and allows the light emitted from the second light source 12 to enter the auxiliary lens 16. A part of the light incident on the auxiliary lens 16 from the incident surface 16a travels to the internal reflection surface 16b, and the other part (the remaining part) travels directly to the output surface 16c.

  The internal reflection surface 16 b reflects a part of the light incident from the incident surface 16 a to the output surface 16 c in the auxiliary lens 16. The internal reflection surface 16b is formed by a reflection process such as deposition of aluminum on the back surface thereof, that is, the outer surface of the auxiliary lens 16. The internal reflection surface 16b is based on an ellipse whose optical focus is in the vicinity of the second light source 12 and the vicinity of the tip edge 15a of the shade 15 is the second focus in consideration of refraction at the incident surface 16a. It is a free-form surface. The internal reflection surface 16b reflects part of the light incident from the incident surface 16a to the output surface 16c. In addition, as long as it reflects as above-mentioned, the internal reflection surface 16b may utilize a total reflection without performing a reflection process, for example, may be another structure, and is not limited to the structure of Example 1. FIG.

  The exit surface 16c is provided opposite to the projection lens 17 in the optical axis direction, and does not enter the internal reflection surface 16b of the light reflected by the internal reflection surface 16b or the light incident from the incident surface 16a. The other part which is the emitted light is emitted to the outside of the auxiliary lens 16. The emission surface 16 c emits the light reflected by the internal reflection surface 16 b so as to travel to the projection lens 17. Therefore, the auxiliary lens 16 functions as a light guide that guides a part of the light emitted from the second light source 12 to the projection lens 17 side. Further, the emission surface 16 c emits the other part of the light incident from the incident surface 16 a so as to travel to the reflection surface 15 b of the shade 15. The other part of this light travels to the projection lens 17 by being reflected by the reflecting surface 15b.

  The auxiliary lens 16 of Example 1 is formed of a cylindrical lens that extends in the width direction and has a refractive power only in the optical axis direction, corresponding to the fact that the second light source 12 is composed of five light source portions 12a. The heat sink member 13 is provided. The auxiliary lens 16 has a focal line extending in the width direction along the five light source parts 12a. The auxiliary lens 16 is not limited to the configuration of the first embodiment as long as it functions as a light guide that guides part of the light emitted from the second light source 12 to the projection lens 17.

  The projection lens 17 has a rear focal point set in the vicinity of the front end edge 15 a of the shade 15. The projection lens 17 projects the light emitted from the first light source 11 and reflected by the reflecting surface 22 of the reflector 14 to the front of the vehicle to form a passing light distribution pattern LP (see FIG. 2). Further, the projection lens 17 projects a part of the light emitted from the second light source 12 reflected by the internal reflection surface 16b of the auxiliary lens 16 to the front of the vehicle, so that the running light distribution pattern HP (FIG. 2). Reference). Further, the projection lens 17 projects the other part of the light emitted from the second light source 12 reflected by the reflecting surface 15b of the shade 15 to the front of the vehicle, and the auxiliary light distribution pattern AP (see FIG. 2). Form.

  The projection lens 17 is supported by a lens holder. The lens holder is assembled to the heat sink member 13 with the projection lens 17 positioned relative to the auxiliary lens 16 on the first light source 11, the second light source 12, the reflector 14, and the shade 15.

  The vehicular lamp 10 appropriately turns on the first light source 11 by supplying power from the lighting control circuit to the first light source 11 from the substrate 20. By this lighting, the vehicular lamp 10 reflects the light from the first light source 11 by the reflecting surface 22 of the reflector 14 and projects it by the projection lens 17, thereby passing the light distribution pattern for passing having a cutoff line Cl at the upper edge. LP (see FIG. 2) is formed.

  Moreover, the vehicle lamp 10 supplies the electric power from the lighting control circuit to each light source unit 12a of the second light source 12 from the substrate 21, thereby appropriately lighting the second light source 12 (each light source unit 12a). With this lighting, the vehicular lamp 10 causes a part of the light from the second light source 12 to be incident on the auxiliary lens 16 from the incident surface 16a and reflected by the internal reflection surface 16b, and from the output surface 16c to the auxiliary lens 16. The light is emitted outward and advanced to the projection lens 17. Then, the vehicular lamp 10 projects the light by the projection lens 17, thereby forming a traveling light distribution pattern HP (see FIG. 2) so that the lower end portion overlaps the upper end portion of the passing light distribution pattern LP. .

  Further, the vehicular lamp 10 causes the other part of the light from the lighted second light source 12 (each light source part 12a) to enter the auxiliary lens 16 from the incident surface 16a and to the outside of the auxiliary lens 16 from the output surface 16c. The light is emitted and advanced to the reflecting surface 15b of the shade 15. The vehicular lamp 10 reflects the light at the reflecting surface 15b, travels to the projection lens 17 and is projected by the projection lens 17, so that the vehicular lamp 10 overlaps the approximately upper half of the traveling light distribution pattern HP. The auxiliary light distribution pattern AP (see FIG. 2) is formed so as to illuminate even above the light distribution pattern HP. Note that the vehicular lamp 10 can form the auxiliary light distribution pattern AP by reflecting the other part of the light from the second light source 12 by the reflection surface 15b of the shade 15 and projecting it by the projection lens 17. The light may be directly advanced to the reflecting surface 15b without being incident on the auxiliary lens 16, and is not limited to the configuration of the first embodiment.

  The vehicular lamp 10 according to the first embodiment is an ADB (Adaptive Driving Beam), and when the five light source parts 12a of the second light source 12 are turned on, each of the light source parts 12a emits light. Each light forms a traveling light distribution part hp (see FIG. 2). The five travel light distribution portions hp are integrally formed side by side in the width direction to form a travel light distribution pattern HP (see FIG. 2). And the vehicle lamp 10 enables partial light extinction in a specific direction among the five travel light distribution parts hp by individually turning on and off each light source part 12a of the second light source 12. (See FIG. 3). Thus, the vehicular lamp 10 can be partially turned off in any direction in the travel light distribution pattern HP by individually turning on and off the light sources 12a.

  At this time, the vehicular lamp 10 according to the first embodiment is formed so as to overlap the upper half of the traveling light distribution pattern HP even when the traveling light distribution pattern HP is partially turned off in a specific direction. In the auxiliary light distribution pattern AP, it is assumed that partial extinction does not occur. This is because the vehicular lamp 10 is subjected to surface treatment on the lower surface of the shade 15 to form a reflecting surface 15b, and the auxiliary light distribution pattern is similar to each traveling light distribution portion hp of the traveling light distribution pattern HP. This is because the AP is not formed separately for each light source unit 12a. As a result, the vehicular lamp 10 can leave the auxiliary light distribution pattern AP above it even when any direction of the travel light distribution pattern HP is partially turned off, thereby suppressing the passenger from feeling uncomfortable. it can. Note that the vehicular lamp 10 may be formed by dividing the auxiliary light distribution pattern AP for each light source unit 12a as in the respective travel light distribution portions hp of the travel light distribution pattern HP. It is not limited to the configuration.

  For this reason, the vehicular lamp 10 can form the passing light distribution pattern LP having the cut-off line Cl by turning on the first light source 11, and run by turning on each light source part 12 a of the second light source 12. The light distribution pattern HP and the auxiliary light distribution pattern AP can be formed (see FIG. 2). The vehicular lamp 10 controls the lighting of the light source portions 12a of the first light source 11 and the second light source 12, thereby providing the passing light distribution pattern LP, the traveling light distribution pattern HP, and the auxiliary light distribution pattern AP. At the same time or only one can be formed as appropriate. In addition, the vehicular lamp 10 does not form only the traveling light distribution part hp in the corresponding direction by turning off the light source part 12a located in an arbitrary direction among the light source parts 12a of the second light source 12. And the ADB function can be realized (see FIG. 3).

  As described above, the vehicular lamp 10 guides the auxiliary lens 16 provided above the second light source 12 to the projection lens 17 only for part of the light emitted from the second light source 12. The other part of the light emitted from the light is advanced to the projection lens 17 by reflection on the reflection surface 15 b of the shade 15. For this reason, the vehicular lamp 10 does not need to reflect all of the light from the second light source 12 to the projection lens 17 side as in the conventional translucent member. The configuration of the surface 16b and the exit surface 16c can be minimized, and the auxiliary lens 16 can be made small. Here, all of the light from the second light source 12 exceeds the predetermined intensity of the light emitted from the second light source 12, and is a control target for forming a predetermined light distribution pattern. Light. Thereby, the vehicular lamp 10 is emitted from the first light source 11 and reflected by the reflector 14 even when the second light source 12 is provided at the same position (on the same plane) as the first light source 11 in the vertical direction. It is possible to prevent the auxiliary lens 16 from obstructing the progress of the light traveling toward. Therefore, the vehicular lamp 10 can flatten the place (the upper surface 13a in the first embodiment) to which the first light source 11 and the second light source 12 are attached, and the shape of the member to which they are attached (the heat sink member 13 in the first embodiment). The first light source 11 and the second light source 12 can be provided on the same plane. In addition, since the board | substrate 20 and the board | substrate 21 are provided on the upper surface 13a used as the same plane, it is good also as an integrated single board | substrate.

  In particular, in the vehicular lamp 10 according to the first embodiment, the first light source 11 and the second light source 12 are attached to the heat sink member 13 via the substrate 20 and the substrate 21. Here, generally in a heat sink, heat is transferred radially from a heat source, so that a cooling capacity can be enhanced by securing a concentrically large volume centered on the heat source. Since the vehicular lamp 10 has a flat upper surface 13a of the heat sink member 13, the first light source 11 and the first light source 11 are not partially lost due to the step as compared with the step provided on the upper surface 13a. It becomes easy to secure a concentric spherical portion having a large volume below each of the two light sources 12. Therefore, the vehicular lamp 10 can secure a volume for transferring heat to each of the first light source 11 and the second light source 12 in the heat sink member 13, and the first light source 11 and the second light source 12 can be secured. Proper cooling is possible.

  Moreover, the vehicular lamp 10 has a tip 15a of the shade 15 that is sharp, and is provided with an auxiliary lens 16 in proximity to the shade 15. For this reason, since the vehicular lamp 10 can be set in the vicinity of the rear focal point of the projection lens 17, the optical path forming the passing light distribution pattern LP and the optical path forming the traveling light distribution pattern HP can be set close to each other. The passing light distribution pattern LP and the traveling light distribution pattern HP can be formed to overlap each other.

  The vehicular lamp 10 according to the first embodiment can obtain the following effects.

  In the vehicular lamp 10, the auxiliary lens 16 as a light guide part guides part of the light emitted from the second light source 12 to the projection lens 17 side, and assists the other part of the light emitted from the second light source 12. The light is reflected by the shade 15 provided above the lens 16 toward the projection lens 17. For this reason, the vehicular lamp 10 causes the light emitted from the second light source 12 to be shared by the auxiliary lens 16 and the shade 15 and to travel to the projection lens 17. For this reason, the vehicular lamp 10 can have a small configuration of the auxiliary lens 16, and the first light source 11 and the second light source 12 are emitted from the first light source 11 even if they are provided in the same position (on the same plane) in the vertical direction. Thus, it is possible to prevent the auxiliary lens 16 from blocking the light reflected by the reflecting surface 22 and traveling toward the projection lens 17. Thereby, the vehicular lamp 10 can simplify the shape of the member to which the first light source 11 and the second light source 12 are attached. Moreover, the vehicular lamp 10 can also provide the first light source 11 and the second light source 12 on a common substrate in which the substrate 20 and the substrate 21 are integrated.

  In the vehicular lamp 10, the first light source 11 and the second light source 12 are provided on the upper surface 13 a of the heat sink member 13. For this reason, since the vehicle lamp 10 does not need to provide a level | step difference in the upper surface 13a, the 1st light source 11 and the 2nd light source 12 can be cooled appropriately.

  In the vehicular lamp 10, the projection lens 17 projects the light guided by the auxiliary lens 16 to the front side in the optical axis direction to form a traveling light distribution pattern HP above the passing light distribution pattern LP, and the shade 15 The light reflected by the reflecting surface 15b is projected on the front side in the optical axis direction, and is superimposed on the upper half of the traveling light distribution pattern HP, and the auxiliary light distribution pattern AP is formed thereabove. For this reason, the vehicular lamp 10 forms the shade 15 (its front edge 15a), that is, the passing light distribution pattern LP, between the light path forming the traveling light distribution pattern HP and the light path forming the auxiliary light distribution pattern AP. It can be set close to the optical path. Thus, the vehicular lamp 10 can be formed by overlapping the passing light distribution pattern LP and the traveling light distribution pattern HP, and can also form the auxiliary light distribution pattern AP by overlapping the traveling light distribution pattern HP.

  The vehicular lamp 10 forms a travel light distribution pattern HP by paralleling a plurality of travel light distribution portions hp formed by light from each of the plurality of light source portions 12a of the second light source 12 in the width direction. . For this reason, the vehicular lamp 10 individually turns on and off each light source unit 12a of the second light source 12 that has been appropriately cooled, so that the distribution for traveling in a specific direction among the plurality of traveling light distribution units hp is performed. The optical part hp can be partially turned off, and the ADB function can be realized more appropriately.

  In the vehicular lamp 10, the light guide unit is configured by an auxiliary lens 16 formed of a transmission member that allows a part of light emitted from the second light source 12 to enter. For this reason, the vehicular lamp 10 can make a part of the light emitted from the second light source 12 enter the auxiliary lens 16 and guide it to the projection lens 17 side with a simple configuration.

  Therefore, the vehicular lamp 10 according to the first embodiment as the vehicular lamp 10 according to the present disclosure forms the first light source 11 and the second light source while forming the passing light distribution pattern LP and the traveling light distribution pattern HP so as to overlap each other. 12 can be provided without any step.

  As mentioned above, although the vehicle lamp of this indication was demonstrated based on Example 1, it is not restricted to Example 1 about a concrete structure, It deviates from the summary of the invention which concerns on each claim of a claim Unless otherwise, design changes and additions are permitted.

  In the first embodiment, it is assumed that the function of ADB can be realized by not forming an arbitrary traveling light distribution part hp in the traveling light distribution pattern HP. However, the vehicular lamp 10 reflects the light from the first light source 11 by the reflector 14 and projects it by the projection lens 17 to form a passing light distribution pattern LP, and the light from the second light source 12 is transmitted by the light guide unit. Any configuration may be used as long as the traveling light distribution pattern HP is projected by the guidance projection lens 17 and is not limited to the configuration of the first embodiment.

  In the first embodiment, the light guide unit is configured by the auxiliary lens 16 formed of a transmission member that allows a part of the light emitted from the second light source 12 to enter. However, the light guide section is not limited to the configuration of the first embodiment as long as the light guide section (16) guides part of the light emitted from the second light source 12 to the projection lens 17 side. As another example, the light guide portion can be formed of a reflecting member such as a mirror that reflects a part of the light emitted from the second light source 12. In this case, since the light guide (reflecting member) can have only a reflection surface similar to the internal reflection surface 16b, the light guide portion can have a simpler configuration and can be used in addition to the light emitted from the second light source 12. The portion can be directly advanced to the shade 15 (its reflecting surface 15b) without passing through the incident surface 16a and the exit surface 16c, and the optical setting can be simplified.

  In Example 1, the auxiliary lens 16 is a cylindrical lens. However, the auxiliary lens 16 is not limited to the configuration of the first embodiment as long as it corresponds to a plurality (five in the first embodiment) of the second light sources 12 and five light source sections 12a. As another example, for example, a plurality of lenses may be provided corresponding to each light source unit 12a individually, or a free-form surface lens having an entrance surface and an exit surface may be provided for each light source unit 12a. Good. The free-form surface lens may be provided separately for each light source unit 12a, or may be an integrated unit corresponding to each light source unit 12a.
