Description

  The present invention relates to a projector-type vehicular lamp provided with a reflector.

  In general, in a projector-type vehicular lamp, a light distribution pattern is formed by reversely projecting a light source image formed on the rear focal plane of a projection lens to the front.

  “Patent Document 1” describes such a projector-type vehicular lamp configured such that light from a light source is reflected by a reflector toward a projection lens.

JP 2008-243432 A

  In the vehicle lamp described in the above-mentioned “Patent Document 1”, not only light from the light source reflected by the reflector but also part of direct light from the light source is incident on the projection lens. There is a problem.

  That is, the direct light from the light source is incident on the rear surface of the projection lens over a wide range. At this time, the light that has reached the peripheral edge of the projection lens is projected by the reflected light from the reflector when it is emitted from the projection lens. The light travels in a direction greatly deviating from the original light irradiation direction emitted from the lens, and the light is not controlled. In addition, there is a problem in that the non-controlled light causes light unevenness such as a light pool or a light streak around the light distribution pattern.

  On the other hand, if the direct light traveling from the light source to the projection lens is shielded by a shade or the like, it is possible to prevent the occurrence of light unevenness around the light distribution pattern. However, in such a case, a part of the reflected light from the reflector is shielded by the shade or the like, so that there is a problem that the brightness of the light distribution pattern is reduced by that amount.

  The present invention has been made in view of such circumstances, and in a projector-type vehicular lamp equipped with a reflector, the brightness of the light distribution pattern is sufficiently ensured and light unevenness occurs around the light distribution pattern. An object of the present invention is to provide a vehicular lamp that can suppress the occurrence of the lamp.

  In the present invention, the first and second sub-reflectors are provided, and the arrangement is devised to achieve the above object.

That is, the vehicular lamp according to the present invention is
In a vehicular lamp comprising: a projection lens; a light source disposed behind the rear focus of the projection lens; and a reflector that reflects light from the light source toward the projection lens.
A first sub-reflector that reflects direct light from the light source toward the projection lens toward the front of the reflector is disposed in front of the light source,
A second sub-reflector that reflects the reflected light from the first sub-reflector toward the projection lens is disposed behind the projection lens.

  The type of the “light source” is not particularly limited, and for example, a light emitting element such as a light emitting diode or a laser diode, a light source bulb, or the like can be employed.

  As long as the “reflector” is configured to reflect the light from the light source toward the projection lens, the specific arrangement, reflecting surface shape, and the like are not particularly limited.

  If the “first sub-reflector” is configured to reflect the direct light from the light source toward the projection lens in front of the light source toward the front of the reflector, the specific arrangement, the shape of the reflecting surface, etc. It is not limited.

  If the “second sub-reflector” is configured to reflect the reflected light from the first sub-reflector toward the projection lens behind the projection lens, the specific arrangement, the shape of the reflecting surface, and the like are particularly limited. Is not to be done.

  As shown in the above configuration, the vehicular lamp according to the present invention is configured to reflect the light from the light source toward the projection lens by the reflector, but in front of the light source, from the light source to the projection lens. A first sub-reflector that reflects the direct directing light toward the front of the reflector is disposed, and a second sub that reflects the reflected light from the first sub-reflector toward the projection lens is disposed behind the projection lens. Since the reflector is arranged, the following effects can be obtained.

  In other words, the presence of the first sub-reflector can prevent or suppress direct light from the light source from reaching the projection lens. As a result, it is possible to prevent or suppress the occurrence of light unevenness around the light distribution pattern due to emission of uncontrolled light from the projection lens.

  Further, due to the presence of the second sub-reflector, the light from the light source reflected by the first sub-reflector can be reflected toward the projection lens. Since the reflected light from the second sub-reflector becomes controlled light, the brightness of the light distribution pattern can be increased by emitting the reflected light from the projection lens.

  At that time, not only the direct light from the light source but also part of the reflected light from the reflector reaches the first sub-reflector. The reflected light from the reflector that has reached the first sub-reflector in this way can also be reflected by the second sub-reflector and emitted from the projection lens, thereby contributing to the formation of the light distribution pattern.

  As described above, according to the present invention, in the projector-type vehicular lamp provided with the reflector, the brightness of the light distribution pattern can be sufficiently secured, and the occurrence of light unevenness around the light distribution pattern can be suppressed. it can.

  In the above configuration, if the second sub-reflector is configured to reflect the reflected light from the first sub-reflector toward the rear focal point of the projection lens or the vicinity thereof, the reflection from the second sub-reflector. The central luminous intensity of the light distribution pattern can be increased by the light.

  In the above configuration, if the reflecting surface of the second sub-reflector is formed with a rotating paraboloid focusing on a point in the vicinity of the reflecting surface of the first sub-reflector as a reference surface, the reflection from the second sub-reflector The light can be well controlled light. And thereby, the luminous intensity distribution of a light distribution pattern can be adjusted appropriately.

  In the above configuration, if the light source is configured by a light emitting element disposed with the light emitting surface facing downward, and the reflector is disposed below the light source, the following operational effects can be obtained.

  That is, by adopting such a configuration, the direct light from the light source and the reflected light from the reflector reach the first sub-reflector from substantially the same direction. It is possible to easily reflect the sub reflector toward the second sub reflector.

  At that time, if the first sub-reflector does not exist, the direct light from the light source emitted from the peripheral portion of the projection lens is applied to the upper space of the light distribution pattern, and is thus installed on the vehicle front road. Since uneven light is reflected on an overhead sign or the like, it is particularly effective to adopt the configuration of the present invention.

  In addition, by configuring the light source with the light emitting elements arranged with the light emitting surface facing downward, it is possible to improve the heat dissipation with respect to the heat generated by the light source.

  In the above configuration, the light source is configured by a light emitting element disposed with the light emitting surface facing upward, and the reflector is disposed above the light source, and the reflector is disposed between the light source and the projection lens. If the cut-off forming member for forming the cut-off line is arranged at the upper end of the light distribution pattern formed by the reflected light, the low beam light distribution pattern and the like can be easily formed.

  Even in such a configuration, the direct light from the light source and the reflected light from the reflector reach the first sub-reflector from substantially the same direction. It is possible to easily reflect the light toward the second sub reflector in the reflector.

  At this time, if the first sub-reflector does not exist, the direct light from the light source emitted from the projection lens is irradiated to the lower space of the light distribution pattern, so that light is collected in a short distance area on the road surface in front of the vehicle. Since the streak of light and light are clearly formed, it is particularly effective to adopt the configuration of the present invention.

  The specific configuration of the “cut-off forming member” is not particularly limited, and for example, a shade or a mirror member having an upward reflecting surface can be employed.

The same figure as FIG. 3 which shows the said modification. The same figure as FIG. 4 which shows the effect | action of the said modification.

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

  FIG. 1 is a front view showing a vehicular lamp 10 according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along line II-II. FIG. 3 is a plan view showing the vehicle lamp.

  As shown in these drawings, the vehicular lamp 10 according to the present embodiment includes a projection lens 12, a light emitting element 14 disposed behind the rear focal point F of the projection lens 12, and the light emitting element 14. Is disposed on the lower side, and includes a reflector 16 that reflects light from the light emitting element 14 toward the projection lens 12, and first and second sub-reflectors 18 and 20.

  This vehicular lamp 10 is a high beam lamp unit used in a state where it is incorporated as a part of a headlamp, and is arranged so that the optical axis Ax of the projection lens 12 extends in the vehicle front-rear direction. It has become.

  The projection lens 12 is a plano-convex aspheric lens having a convex front surface and a flat rear surface, and a light source image formed on the rear focal plane, which is a focal plane including the rear focal point F, as a reverse image in front of the lamp. It is designed to project onto a virtual vertical screen. The projection lens 12 is supported by the lens holder 22 at the outer peripheral flange portion. The lens holder 22 is supported by the base member 24.

  The light emitting element 14 is a white light emitting diode and has a light emitting surface 14a having a horizontally long rectangular shape. The light emitting element 14 is disposed in a state where the light emitting surface 14a is directed downward on the optical axis Ax and extends in the vehicle width direction.

  The light emitting element 14 is supported by a light source support member 26 having a function as a heat sink. The light source support member 26 is configured as a plate-like member whose lower surface extends along a horizontal plane including the optical axis Ax, and is supported by the base member 24.

  The reflector 16 is disposed so as to cover the light emitting element 14 from below, and is supported on the lower surface of the light source support member 26.

  The reflecting surface 16a of the reflector 16 has an elliptical shape in which the vertical sectional shape along the optical axis Ax has an emission center of the light emitting element 14 as a first focal point and a rear focal point F of the projection lens 12 as a second focal point. The eccentricity is set so that the eccentricity gradually increases from the vertical cross section toward the horizontal cross section. As a result, the reflector 16 converges the light from the light emitting element 14 to the rear focal point F in the vertical section, and moves the convergence position considerably forward in the horizontal section.

  The first sub reflector 18 is disposed in front of the light emitting element 14 and is supported by the light source support member 26.

  The reflection surface 18a of the first sub-reflector 18 is formed of a substantially spherical concave surface. The first sub-reflector 18 reflects the direct light from the light emitting element 14 toward the projection lens 12 toward the front side of the reflector 16 downward. At this time, the reflection surface 18a of the first sub-reflector 18 is formed to have a minimum size within a range where the direct light from the light emitting element 14 toward the projection lens 12 can be completely blocked.

  By arranging the first sub-reflector 18, part of the light from the light emitting element 14 reflected by the reflector 16 reaches the reflecting surface 18 a of the first sub-reflector 18, and the front side of the reflector 16. It will be reflected downwards toward.

  The second sub reflector 20 is arranged behind the projection lens 12. Specifically, the second sub-reflector 20 is disposed near the front of the reflector 16 and is formed integrally with the reflector 16.

  The reflecting surface 20a of the second sub-reflector 20 is formed as a rotating paraboloid focusing on a point located near the upper surface of the reflecting surface 18a of the first sub-reflector 18. The second sub-reflector 20 reflects the reflected light from the first sub-reflector 18 toward the rear focal point F.

  FIG. 4 is a perspective view showing a high-beam light distribution pattern PH formed on a virtual vertical screen disposed at a position 25 m ahead of the lamp by light emitted forward from the vehicular lamp 10.

  The high beam light distribution pattern PH is formed as a combined light distribution pattern of the basic light distribution pattern PH0 and the two additional light distribution patterns Pa1 and Pa2.

  The basic light distribution pattern PH0 is a light distribution pattern formed by light from the light emitting element 14 that is reflected by the reflector 16 and reaches the projection lens 12 as it is. The basic light distribution pattern PH0 is formed as a light distribution pattern that greatly expands in the left-right direction around HV.

  The additional light distribution pattern Pa <b> 1 is a light distribution pattern formed by light from the light emitting element 14 that is sequentially reflected by the first sub-reflector 18 and the second sub-reflector 20 and reaches the projection lens 12. This additional light distribution pattern Pa1 is formed as a light distribution pattern smaller than the basic light distribution pattern PH0 that extends in the left-right direction around a point located slightly above HV.

  The additional light distribution pattern Pa <b> 2 is a light distribution pattern formed by light from the light emitting element 14 that is sequentially reflected by the reflector 16, the first sub-reflector 18, and the second sub-reflector 20 and reaches the projection lens 12. This additional light distribution pattern Pa2 is formed as a light distribution pattern smaller than the basic light distribution pattern PH0 that extends in the left-right direction around a point located slightly below HV.

  In FIG. 4, the light distribution pattern Pa ′ indicated by a two-dot chain line indicates that the light emitting element 14 that has reached the peripheral edge of the projection lens 12 when the first sub-reflector 18 is not disposed in front of the light emitting element 14. It is a light distribution pattern formed by the direct light from. This light distribution pattern Pa ′ is formed at a position greatly deviated upward from HV and is formed by light that is not sufficiently controlled. Therefore, a light pool or light streak is formed in the upper space of the vehicle front road. As a result, light unevenness such as the above will occur. And this light nonuniformity will be reflected in the overhead sign etc. which were installed in the vehicle front road.

  Next, the effect of this embodiment is demonstrated.

  The vehicular lamp 10 according to the present embodiment is configured to reflect the light from the light emitting element 14 (that is, the light source) toward the projection lens 12 by the reflector 16. A first sub-reflector 18 that reflects direct light from the light emitting element 14 toward the projection lens 12 toward the front of the reflector 16 is disposed, and the reflection from the first sub-reflector 18 is disposed behind the projection lens 12. Since the second sub-reflector 20 that reflects light toward the projection lens 12 is disposed, the following operational effects can be obtained.

  That is, the presence of the first sub-reflector 18 can prevent direct light from the light emitting element 14 from reaching the projection lens 12. As a result, it is possible to prevent light unevenness from occurring around the high-beam light distribution pattern PH due to emission of uncontrolled light from the projection lens 12.

  Further, the presence of the second sub-reflector 20 allows the light from the light emitting element 14 reflected by the first sub-reflector 18 to be reflected toward the projection lens 12. Since the reflected light from the second sub-reflector 20 is controlled light, the brightness of the high beam light distribution pattern PH can be increased by emitting the reflected light from the projection lens 12.

  At that time, not only the direct light from the light emitting element 14 but also a part of the reflected light from the reflector 16 reaches the first sub-reflector 18. The reflected light from the reflector 16 that has reached the first sub-reflector 18 in this way is also reflected by the second sub-reflector 20 and emitted from the projection lens 12, thereby forming a high-beam light distribution pattern PH. Can contribute.

  As described above, according to the present embodiment, in the projector-type vehicular lamp 10 including the reflector 16, the brightness of the high-beam light distribution pattern PH is sufficiently ensured, and light unevenness occurs around the light beam distribution pattern PH. Can be suppressed.

  At this time, in the present embodiment, the second sub-reflector 20 is configured to reflect the reflected light from the first sub-reflector 18 toward the rear focus F of the projection lens 12. The central light intensity of the high beam light distribution pattern PH can be increased by the reflected light from the reflector 20.

  Further, in the present embodiment, the reflecting surface of the second sub-reflector 20 is composed of a rotating paraboloid focusing on a point near the reflecting surface of the first sub-reflector 18. The reflected light can be a sufficiently controlled light. Thereby, the luminous intensity distribution of the high beam light distribution pattern PH can be appropriately adjusted.

  In particular, in the present embodiment, the light source of the vehicular lamp 10 is composed of the light emitting element 14 disposed with the light emitting surface 14a facing downward, and the reflector 16 is disposed below the light emitting element 14. Therefore, the following effects can be obtained.

  That is, the direct light from the light emitting element 14 and the reflected light from the reflector 16 reach the first sub reflector 18 from substantially the same direction. Reflection toward the two-sub-reflector 20 can be easily performed.

  At this time, if the first sub-reflector 18 does not exist, the direct light from the light emitting element 14 emitted from the projection lens 12 is applied to the space above the high-beam light distribution pattern PH, which causes the road ahead of the vehicle. However, it is possible to prevent the occurrence of such a problem in advance.

  Further, in the present embodiment, the light source support member 26 that supports the light emitting element 14 disposed with the light emitting surface 14a facing downward functions from the upper side as a heat sink, so that heat dissipation with respect to the heat generated by the light emitting element 14 is improved. be able to.

  In the above embodiment, the second sub-reflector 20 has been described as configured to reflect the reflected light from the first sub-reflector 18 toward the rear focal point F of the projection lens 12, but the rear side Even when it is configured to reflect toward the vicinity of the focal point F, the central light intensity of the high beam light distribution pattern PH can be increased by the reflected light from the second sub-reflector 20.

  In the said embodiment, although the reflective surface of the 2nd sub reflector 20 demonstrated as what was comprised by the rotating paraboloid which made the focus the point of the reflective surface vicinity of the 1st sub reflector 18, this rotating paraboloid was demonstrated. If the surface is a curved surface with a reference surface, the reflected light from the second sub-reflector 20 can be made a sufficiently controlled light, thereby appropriately adjusting the luminous intensity distribution of the high beam light distribution pattern PH. Can be adjusted.

  In the above embodiment, the second sub-reflector 20 is described as being formed integrally with the reflector 16, but a configuration in which the second sub-reflector 20 is formed separately from the reflector 16 is also possible.

  Next, a modification of the above embodiment will be described.

  5, 6 and 7 are views similar to FIGS. 2, 3 and 4 showing a vehicular lamp 110 according to this modification.

  As shown in these drawings, the vehicular lamp 110 according to the present modification is a low beam lamp unit, and when incorporated in a headlamp, the optical axis Ax of the projection lens 12 is in the vehicle front-rear direction. On the other hand, it is arranged in a state extending in a downward direction by about 0.5 to 0.6 °.

  The basic configuration of the vehicular lamp 110 is the same as that of the above embodiment, but differs from the above embodiment in the following points.

  That is, in this modification, the orientations of the light emitting element 14, the reflector 16, the first sub-reflector 18, and the second sub-reflector 20 are arranged in a position that is upside down with respect to the horizontal plane including the optical axis Ax. These are disposed at a position closer to the rear focal point F of the projection lens 12 than the case of the above embodiment (ie, a position closer to the front). Further, in this modification, the mirror member 130 having the upward reflecting surface 130a for reflecting a part of the reflected light from the reflector 16 upward between the light emitting element 14 and the projection lens 12 is cut off. It is arranged as a member.

  The mirror member 130 is formed integrally with the base member 124. The base member 124 also has a function as the light source support member 26 of the above embodiment.

  The upward reflecting surface 130a of the mirror member 130 is formed by subjecting the upper surface of the mirror member 130 to a mirror surface treatment such as aluminum vapor deposition. In the upward reflecting surface 130a, the left region located on the left side (right side in the front view of the lamp) from the optical axis Ax is configured by a horizontal plane including the optical axis Ax, and the right region located on the right side from the optical axis Ax It is composed of a horizontal plane that is one step lower than the left region through a short slope. The front edge 130a1 of the upward reflecting surface 130a extends from the rear focal point F toward the left and right sides so as to curve forward along the meridional image plane of the projection lens 12. The upward reflecting surface 130a is formed in a region within a range from the front end edge 130a1 to a position away from the rear side by a certain distance.

  The mirror member 130 reflects a part of the reflected light from the reflecting surface 16a of the reflector 16 toward the projection lens 12 upward on the upward reflecting surface 130a so as to be incident on the projection lens 12, and uses these as downward light. The light is emitted from the projection lens 12.

  In the present modification, the light emitting element 14, the reflector 16, the first sub-reflector 18, and the second sub-reflector 20 are displaced forward relative to the rear focal point F of the projection lens 12. The reflected light from 16 and the reflected light from the second sub-reflector 20 intersect with the horizontal plane including the optical axis Ax slightly ahead of the above embodiment.

  FIG. 8 is a perspective view of the low beam light distribution pattern PL formed on the virtual vertical screen by the light emitted forward from the vehicular lamp 110.

  This low beam light distribution pattern PL is a left light distribution pattern for low beam, and has upper and lower cut-off lines CL1 and CL2 at its upper edge. The cut-off lines CL1 and CL2 extend in the horizontal direction at the left and right steps with the VV line passing through the HV, which is a vanishing point in the front direction of the lamp, in the vertical direction, and are on the right side of the VV line. The opposite lane side portion is formed as a lower cut-off line CL1, and the own lane side portion on the left side of the VV line is formed as an upper cut-off line CL2 that rises from the lower cut-off line CL1 through an inclined portion. Is formed.

  In this low beam distribution pattern PL, the elbow point E, which is the intersection of the lower cut-off line CL1 and the VV line, is located about 0.5 to 0.6 ° below HV. This is because the optical axis Ax extends in a downward direction by about 0.5 to 0.6 ° with respect to the vehicle longitudinal direction.

  The low beam light distribution pattern PL is formed as a combined light distribution pattern of the basic light distribution pattern PL0 and the two additional light distribution patterns Pb1 and Pb2.

  The basic light distribution pattern PH0 is reflected by the reflector 16, and then the light from the light emitting element 14 that has reached the projection lens 12 as it is and the light that has reached the projection lens 12 after being reflected upward by the upward reflecting surface 130a of the mirror member 130. It is a light distribution pattern formed by light from the element 14. The basic light distribution pattern PH0 forms the basic shape of the low beam light distribution pattern PL.

  The additional light distribution pattern Pb1 is a light distribution pattern formed by light from the light emitting element 14 that is sequentially reflected by the first sub-reflector 18 and the second sub-reflector 20 and reaches the projection lens 12. The additional light distribution pattern Pb1 is formed as a light distribution pattern smaller than the basic light distribution pattern PL0 that extends in the left-right direction around a point located below the elbow point E.

  The additional light distribution pattern Pb <b> 2 is a light distribution pattern formed by light from the light emitting element 14 that is sequentially reflected by the reflector 16, the first sub-reflector 18, and the second sub-reflector 20 and reaches the projection lens 12. This additional light distribution pattern Pb2 is formed as a light distribution pattern smaller than the basic light distribution pattern PL0 that extends in the left-right direction around a point located slightly below the elbow point E.

  At that time, part of the reflected light from the second sub-reflector 20 is also reflected upward by the upward reflecting surface 130a of the mirror member 130, so that each additional light distribution pattern Pb1, Pb2 is used to form the cut-off lines CL1, CL2. Has also contributed.

  In FIG. 8, the light distribution pattern Pb ′ indicated by a two-dot chain line indicates that the light emitting element 14 that has reached the peripheral edge of the projection lens 12 if the first sub-reflector 18 is not disposed in front of the light emitting element 14. It is a light distribution pattern formed by the direct light from. This light distribution pattern Pb ′ is formed at a position greatly deviated downward from HV, and is formed by light that is not sufficiently controlled. Light irregularities such as streaks are clearly formed.

  Even in the case of adopting the configuration of this modified example, in the projector-type vehicle lamp 110 provided with the reflector 16, the brightness of the low-beam light distribution pattern PL is sufficiently ensured, and light unevenness occurs around the light distribution pattern PL. Can be suppressed.

  At this time, if the first sub-reflector 18 does not exist, the light unevenness is clearly formed in the short distance area on the road surface in front of the vehicle by the direct light from the light emitting element 14 emitted from the projection lens 12. However, it is possible to prevent such a problem from occurring.

  In addition, the numerical value shown as a specification in the said embodiment and its modification is only an example, and of course, you may set these to a different value suitably.

  The invention of the present application is not limited to the configuration described in the above-described embodiment and its modifications, and a configuration with various other changes can be adopted.
