Description

  The present invention relates to a projector-type vehicular lamp having a movable shade.

  Conventionally, as a projector-type vehicular lamp configured to reflect light from a light emitting element arranged behind a rear focal point of a projection lens toward a projection lens by a reflector, the light emitting element and A projector in which a shade is disposed between the projection lens and the projection lens is known.

  In “Patent Document 1” and “Patent Document 2”, as a configuration of such a vehicle lamp, the light emitting element is disposed in a state where the light emitting surface is vertically upward on the lower side of the optical axis of the projection lens. In addition, there is described a configuration in which the reflector is disposed so that the lower end edge thereof is positioned below the optical axis.

  In that case, in the vehicular lamp described in “Patent Document 1”, the shade cancels the light shielding position where the part of the reflected light from the reflector is shielded to form a low beam light distribution pattern, and the light shielding is canceled. Thus, a light shielding release position for forming a high beam light distribution pattern can be adopted.

  On the other hand, the vehicular lamp described in “Patent Document 2” has a configuration in which the light emitting element is disposed in a state in which the direction of the light emitting surface of the light emitting element is inclined backward with respect to the vertical direction. ing.

JP-A-2015-82339 Japanese Patent No. 5212785

  In the vehicular lamp described in the above-mentioned “Patent Document 1”, as the light-emitting element, as in the light-emitting element described in the “Patent Document 2”, the direction of the light-emitting surface is rearward with respect to the upper side in the vertical direction. If it is set as the structure which inclined, it will become possible to comprise a lamp compactly compared with the case where the light emission surface is arrange | positioned vertically upwards.

  However, when such a configuration is adopted, there are the following problems.

  That is, the upper region of the light distribution pattern for high beam is light that passes through the focal plane including the rear focal point of the projection lens, below the optical axis, among the reflected light from the reflector when the shade moves to the light shielding release position. In order to form the upper region brightly and substantially uniformly, it is preferable to use the reflected light from the lower reflection region of the reflector.

  However, since the light emitting element described in the above-mentioned “Patent Document 2” is arranged at a rearward tilt angle such that the extended plane of the light emitting surface passes through the rear focal point of the projection lens, it is reflected by the lower reflection region of the reflector. Thus, the light passing under the rear focal point of the projection lens is blocked by the light emitting element and its supporting member. For this reason, the reflected light from the lower reflection area of the reflector cannot be used effectively, and therefore the upper area of the high beam light distribution pattern cannot be formed brightly and substantially uniformly.

  The present invention has been made in view of such circumstances, and in a projector-type vehicle lamp provided with a movable shade, the upper region of the high beam light distribution pattern is brightly and substantially omitted by a compact lamp configuration. An object of the present invention is to provide a vehicular lamp that can be formed uniformly.

  The present invention is intended to achieve the above object by devising the arrangement of the light emitting elements.

That is, the vehicular lamp according to the present invention is
A projection lens, a light emitting element disposed behind the rear focal point of the projection lens, a reflector that reflects light from the light emitting element toward the projection lens, and the light emitting element and the projection lens. In a vehicle lamp comprising a shade disposed between,
The light emitting element is disposed in a state in which the direction of the light emitting surface of the light emitting element is inclined rearward with respect to the upper vertical direction on the lower side than the optical axis of the projection lens,
The reflector is arranged such that the lower end edge of the reflector is located below the optical axis,
The shade may take a light shielding position where a part of the reflected light from the reflector is shielded to form a low beam light distribution pattern, and a light shielding cancellation position where the light shielding is canceled to form a high beam light distribution pattern. Is configured as
The light emitting element has an angle θ2 formed by an extended plane of the light emitting surface and the optical axis, with respect to an angle θ1 formed by a straight line connecting the light emission center of the light emitting surface and the rear focal point of the projection lens. , Θ2 = 2/6 to 5/6 × θ1 are arranged at a rearward tilt angle having a value within the range.

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

  As long as the “reflector” is arranged so that the lower end edge thereof is located below the optical axis of the projection lens, the specific arrangement, the shape of the reflecting surface, and the like are not particularly limited.

  The “shade” is not particularly limited as long as the “shade” is configured so as to be able to adopt the light shielding position and the light shielding release position.

  The vehicular lamp according to the present invention is configured as a projector-type lamp having a movable shade, and the light-emitting element is oriented on the light emitting surface of the light-emitting element below the optical axis of the projection lens. With respect to the angle θ1 formed by the straight line connecting the emission center of the light emitting surface and the rear focal point of the projection lens with respect to the optical axis. Since the angle θ2 formed by the extended plane of the light emitting surface and the optical axis is arranged at a rearward tilt angle having a value within the range of θ2 = 2/6 to 5/6 × θ1, the following effects can be obtained. Can be obtained.

  That is, since the light emitting element is disposed at a rearward tilt angle in which the angle θ2 is 2/6 or more with respect to the angle θ1, the light emitting element is compared with the case where the light emitting surface is disposed vertically upward. Even if the downward displacement amount from the optical axis and the backward displacement amount from the rear focal point are reduced, the utilization efficiency of the emitted light from the light emitting element can be maintained at substantially the same level. And thereby, a lamp can be comprised compactly.

  On the other hand, since the light emitting element is arranged at a rearward tilt angle where the angle θ2 is 5/6 or less with respect to the angle θ1, it is reflected by the lower reflection region of the reflector and passes below the rear focal point of the projection lens. It is possible to prevent or effectively suppress light from being blocked by the light emitting element and its supporting member. Therefore, the reflected light from the lower reflection area of the reflector can be used effectively, and thereby the upper area of the high beam light distribution pattern can be formed brightly and substantially uniformly.

  As described above, according to the present invention, in the projector-type vehicle lamp provided with the movable shade, the upper region of the high beam light distribution pattern can be formed brightly and substantially uniformly by the compact lamp configuration.

  In the above configuration, if the angle θ2 is set to a value within the range of θ2 = 3/8 to 6/8 × θ1 with respect to the angle θ1, the lamp can be configured compactly and the light distribution pattern for high beams. It is possible to more easily achieve the coexistence of forming the upper region of the lighter and brighter and substantially uniformly.

  In the above configuration, as the configuration of the light emitting element, the emission center of the light emitting surface is located 10 to 15 mm below the optical axis, and the extended plane of the light emitting surface is the focal plane including the rear focal point of the projection lens. If the configuration is arranged so as to intersect at a position 4 to 10 mm below the optical axis, the following effects can be obtained.

  That is, in a vehicular lamp, a projection lens having an effective diameter of about φ60 to 70 is often used. When such a projection lens is used, if the light emitting element is arranged as described above, the lamp can be made compact. This makes it easy to achieve both the bright and substantially uniform formation of the upper region of the high beam light distribution pattern.

It is a figure similar to FIG. 1, Comprising: The figure for demonstrating the item of the said vehicle lamp (A) is a detail view of the main part of FIG. 3, (b) is a diagram showing a conventional vehicle lamp in comparison with (a) It is a figure which shows in perspective the light distribution pattern formed with the irradiation light from the said vehicle lamp, Comprising: (a) is a light distribution pattern for low beams (b) is a figure which shows the light distribution pattern for high beams

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

  FIG. 1 is a side sectional view showing a vehicular lamp 10 according to an embodiment of the present invention. FIG. 2 is a sectional view taken along the line II-II.

  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. The reflector 16 for reflecting the light from the projection lens 12 toward the projection lens 12 and the shade 20 disposed between the light emitting element 14 and the projection lens 12 are provided.

  The projection lens 12 is a plano-convex aspherical lens having a convex front surface 12a and a flat rear surface 12b. A light emitting element image formed on a focal plane including the rear focal point F is used as a reverse image and a virtual vertical position in front of the lamp. It is designed to project on the screen. The projection lens 12 has an effective diameter of about φ60 to 70, and is supported by the lens holder 22 at the outer peripheral flange portion 12c. The lens holder 22 is supported by a base member 24 having a function as a heat sink.

  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 below the optical axis Ax of the projection lens 12 in a state where the direction of the light emitting surface 14a of the light emitting element 14 is inclined rearward with respect to the upper vertical direction.

  The light emitting element 14 is supported by the base member 24 via the light source holder 18. The light source holder 18 is disposed so as to surround the light emitting element 14, and the light emitting element 14 is positioned in this state. The upper surface of the light source holder 18 is formed to extend substantially flush with the light emitting surface 14a.

  The reflector 16 is disposed so as to cover the light emitting element 14 from above. The lower end edge 16b of the reflector 16 is located below the optical axis Ax, and is formed to extend substantially flush with the light emitting surface 14a. And this reflector 16 is supported by the base member 24 in the lower end edge 16b.

  The reflecting surface 16a of the reflector 16 is configured by a substantially elliptical curved surface having the light emission center of the light emitting element 14 as a first focal point. The reflecting surface 16a is set to have an elliptical shape in which the vertical cross-sectional shape along the optical axis Ax is a second focal point located slightly in front of the rear focal point F, and the eccentricity is a horizontal cross-section from the vertical cross-section. It is set to gradually increase toward As a result, the reflector 16 causes the light from the light emitting element 14 to substantially converge to a point located slightly forward of the rear focal point F in the vertical plane and to move the convergence position considerably forward in the horizontal plane. It has become.

  However, the lower reflection area 16aA located below the optical axis Ax on the reflection surface 16a of the reflector 16 has the convergence position of the reflected light from the lower reflection area 16aA and the convergence of the reflected light from the other reflection areas. It is formed in a surface shape that is closer to the rear focal point F than the position.

  The shade 20 is configured as a movable shade that is rotatably supported by a shade holder 28 via a rotation pin 26. At this time, the rotation pin 26 is arranged to extend in the left-right direction below the optical axis Ax and in front of the rear focal point F, and is supported by the base member 24 via the shade holder 28 at both ends thereof. Has been.

  The shade 20 includes a shaft portion 20A through which the rotation pin 26 passes, a slope portion 20B extending obliquely upward from the shaft portion 20A to the rear, and a rear end wall surface extending upward from the rear edge of the slope portion 20B. A portion 20C and a front end wall surface portion 20D extending downward from the shaft portion 20A are provided.

  The rear end wall surface portion 20C is formed to bend and extend forward from the rear focal point F toward the left and right sides in plan view. The upper end edge 20Ca of the rear end wall portion 20C is formed to extend in the horizontal direction with a difference in left and right steps.

  The shade 20 is driven by an actuator 30 supported by the base member 24, and a light shielding position (a position indicated by a solid line in FIG. 1) and a light shielding release position (2 in FIG. 1) rotated by a predetermined angle rearward from the light shielding position. The position indicated by the dotted line) can be taken. The actuator 30 is driven when a beam changeover switch (not shown) is operated.

  When the shade 20 is in the light shielding position, the upper end edge 20Ca thereof is disposed so as to pass through the rear focal point F of the projection lens 12, and thereby a part of the light from the light emitting element 14 reflected by the reflector 16 (mainly lower reflection). The light emitting element reflected by the reflector 16 is displaced by a certain amount below the rear focal point F of the projection lens 12 when the upper edge 20Ca is moved to the light shielding release position while shielding the reflected light from the region 16aA. The light shielding from the light 14 is canceled.

  The front end wall surface portion 20 </ b> D of the shade 20 is formed such that its lower end edge extends to the vicinity of the base member 24. As a result, when the shade 20 is in the light shielding position, the light emitted from the light emitting element 14 is prevented from inadvertently reaching the lower region of the projection lens 12 at the front end wall portion 20D. It is like that.

  FIG. 3 is a diagram similar to FIG. 1 and is a diagram for explaining the specifications of the vehicular lamp 10. In FIG. 3, the vehicular lamp 10 is shown in a state where the shade 20 is in the light shielding release position.

As shown in FIG. 3, the light emitting element 14 has an extension of the light emitting surface 14a with respect to an angle θ1 formed by a straight line L1 connecting the light emitting center of the light emitting surface 14a and the rear focal point F of the projection lens 12 with the optical axis Ax. The angle θ2 formed by the plane P1 and the optical axis Ax is arranged at a backward tilt angle that is a value within the range of θ2 = 2/6 to 5/6 × θ1. Specifically, the angle θ2 is set to a value within the range of θ2 = 3/8 to 6/8 × θ1 with respect to the angle θ1.
At this time, the light emitting element 14 is arranged such that the light emission center of the light emitting surface 14a is located 10-15 mm below the optical axis Ax (that is, A = 10-15 mm in FIG. 3). Further, the light emitting element 14 has an extended plane P1 of the light emitting surface 14a 4 to 10 mm below the optical axis Ax with respect to the focal plane including the rear focal point F of the projection lens 12 (that is, B = 4 to 10 mm in FIG. 3). ) Are arranged so as to intersect at the position.

  In FIG. 3, the light emitting element 114, the reflector 116, the light source holder 118, and the base member 124 constituting the conventional vehicle lamp 110 are indicated by a two-dot chain line. In this conventional vehicle lamp 110, the light emitting surface 114a of the light emitting element 114 is arranged vertically upward.

  As shown in FIG. 3, the vehicular lamp 10 has a smaller amount of downward displacement A from the optical axis Ax of the light emitting element 14 and a rearward displacement C from the rear focal point F than the conventional vehicular lamp 110. Although the value is set, since the light emitting element 14 is tilted backward, the utilization efficiency of the light emitted from the light emitting element 14 is maintained at substantially the same level as that of the conventional vehicle lamp 110. Thus, in the vehicle lamp 10, the distance D from the front end position of the projection lens 12 to the rear end position of the reflector 16 is set to a smaller value than in the case of the conventional vehicle lamp 110.

  FIG. 4A is a detailed view of the main part of FIG. FIG. 4B is a diagram showing a conventional vehicular lamp 210 in comparison with FIG.

  As shown in FIG. 4A, the vehicular lamp 10 is disposed at a rearward tilt angle at which the light emitting surface 14a of the light emitting element 14 has a value in the range of θ2 = 2/6 to 5/6 × θ1. Therefore, the light reflected by the lower reflection region 16aA of the reflector 16 and passing below the rear focal point F of the projection lens 12 is not blocked by the light emitting element 14 or the light source holder 18.

  On the other hand, as shown in FIG. 4B, in the conventional vehicular lamp 210, the light emitting element 214 is supported by the base member 224 via the light source holder 218, but the light emitting surface 214a has θ2 = θ1. It is arranged at a rearward tilt angle. Therefore, the reflected light from the region located near the lower end edge 216b in the lower reflection region 216aA of the reflector 216 is blocked by the light emitting element 214 and the light source holder 218.

  FIG. 5 is a perspective view showing a light distribution pattern formed on a virtual vertical screen disposed at a position 25 m ahead of the vehicle by light emitted from the vehicular lamp 10 to the front of the vehicle. At this time, the light distribution pattern shown in FIG. 5A is the low beam light distribution pattern PL, and the light distribution pattern shown in FIG. 5B is the high beam light distribution pattern PH.

  The light distribution pattern for low beam PL shown in FIG. 5A is a light distribution pattern formed when the shade 20 is in the light shielding position, and is formed as a light distribution pattern for low beam with left light distribution.

  This low beam light distribution pattern PL is obtained by projecting the image of the light emitting element 14 formed on the focal plane including the rear focal point F of the projection lens 12 by the light from the light emitting element 14 reflected by the reflector 16 with the projection lens 12. It is a light distribution pattern formed by projecting as a reverse projection image on a virtual vertical screen.

  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. In the low beam light distribution pattern PL, the high luminous intensity region (that is, the hot zone) HZL is located around the elbow point E.

  A high beam light distribution pattern PH shown in FIG. 6B is a light distribution pattern formed when the shade 20 is at the light shielding release position, and the low beam light distribution pattern PL is located above the cut-off lines CL1 and CL2. It is formed as a horizontally long light distribution pattern extended to the side.

  The high beam light distribution pattern PH is formed so that the upper end edge thereof is positioned about 4 to 6 ° above HV on the VV line. Further, in the high beam light distribution pattern PH, the high luminous intensity region HZH is formed in a horizontally long shape with the center at HV.

  A high beam light distribution pattern PH ′ indicated by a two-dot chain line in FIG. 4B is a high beam light distribution pattern formed by light emitted from the conventional vehicle lamp 210 shown in FIG.

  The high beam light distribution pattern PH ′ is a light distribution pattern in which a region located near the upper edge of the high beam light distribution pattern PH is missing. In the conventional vehicular lamp 210, as shown in FIG. 4B, the reflected light from the region located near the lower edge 216b in the lower reflective region 216aA of the reflector 216 is reflected by the light emitting element 14 and the light source. This is because the light is shielded by the holder 218.

  Next, the effect of this embodiment is demonstrated.

  The vehicular lamp 10 according to the present embodiment is configured as a projector-type lamp having a movable shade 20, and the light emitting element 14 emits the light at a lower side than the optical axis Ax of the projection lens 12. The light emitting surface 14a of the element 14 is disposed in a state in which the direction of the light emitting surface 14a is inclined rearward with respect to the upper vertical direction, and a straight line L1 connecting the light emission center of the light emitting surface 14a and the rear focal point F of the projection lens 12 is formed. An angle θ2 formed by the extended plane P1 of the light emitting surface 14a with respect to the optical axis Ax and an angle θ2 formed by the optical axis Ax is a backward tilt angle that is a value within the range of θ2 = 2/6 to 5/6 × θ1. Therefore, the following effects can be obtained.

  That is, since the light emitting element 14 is arranged at a rearward tilt angle at which the angle θ2 is 2/6 or more with respect to the angle θ1, the light emitting surface as in the conventional vehicle lamp 110 indicated by a two-dot chain line in FIG. Even if the downward displacement amount A from the optical axis Ax of the light emitting element 14 and the backward displacement amount C from the rear focal point F are reduced as compared with the case where 114a is arranged vertically upward, the light emitting element 14 The utilization efficiency of the emitted light can be maintained at substantially the same level. And thereby, a lamp can be comprised compactly.

  On the other hand, since the light emitting element 14 is disposed at a rearward tilt angle at which the angle θ2 is 5/6 or less with respect to the angle θ1, the light emitting element 14 is reflected by the lower reflection region 16aA of the reflector 16 and the rear focal point F of the projection lens 12 is reflected. Can be prevented or effectively suppressed from being blocked by the light emitting element 14 and the light source holder 18. Therefore, the reflected light from the lower reflection region 16aA of the reflector 16 can be used effectively, and thereby the upper region of the high beam light distribution pattern PH can be formed brightly and substantially uniformly.

  As described above, according to the present embodiment, in the projector-type vehicular lamp 10 including the movable shade 20, the upper region of the high-beam light distribution pattern PH is brightly and substantially uniformly formed with a compact lamp configuration. Can do.

  In particular, in the present embodiment, the angle θ2 is set to a value within the range of θ2 = 3/8 to 6/8 × θ1 with respect to the angle θ1, so that the lamp can be made compact and the light distribution for the high beam can be achieved. It becomes easier to achieve both the bright and substantially uniform formation of the upper region of the pattern PH.

  Moreover, although the projection lens 12 of this embodiment has an effective diameter of about φ60 to 70, the light emitting element 14 of this embodiment has a light emission surface 14a whose emission center is 10 to 15 mm below the optical axis Ax. And the extended plane P1 of the light emitting surface 14a is arranged so as to intersect with the focal plane including the rear focal point F of the projection lens 12 at a position 4 to 10 mm below the optical axis Ax. It is possible to easily achieve both a compact configuration of the lamp and a bright and substantially uniform upper region of the high beam light distribution pattern PH.

  In the said embodiment, although the movement of the shade 20 was demonstrated as what is performed by rotation, it can also be set as the structure performed by a reciprocating motion.

  In the above-described embodiment, the vehicular lamp 10 is configured to form the left light distribution low beam light distribution pattern PL, but is configured to form the right light distribution low beam light distribution pattern. Even in such a case, the same effect can be obtained by adopting the same configuration as the above embodiment.

  In addition, the numerical value shown as a specification in the said embodiment 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 embodiment, and configurations with various other changes can be employed.
