Description

  The technology disclosed herein relates to a vehicle headlamp.

  2. Description of the Related Art Conventionally, a vehicle headlamp that has a common light source for a high beam and a low beam and switches between a high beam and a low beam by changing the position of a reflecting member is known.

JP2011-119184A

  By the way, the vehicle headlamp may have a third irradiation mode in addition to the high beam and the low beam. For example, as a 3rd irradiation mode, there exists daytime lighting (DRL: Daytime Running Lights). Daytime lighting is lighting for allowing other people to easily recognize the vehicle, and lighting in a relatively bright environment such as daytime.

  In order to realize such a third irradiation mode, a dedicated irradiation unit may be provided, but it is preferable to suppress an increase in the number of parts as much as possible.

  The technology disclosed herein has been made in view of such a point, and an object thereof is to realize a third irradiation mode other than a high beam and a low beam while suppressing an increase in the number of components. .

  The vehicle headlamp disclosed herein includes a light source, a first reflecting member for reflecting light from the light source, a first position for forming a low beam alignment pattern, and a second for forming a high beam alignment pattern. A second reflection member configured to reflect the light reflected by the first reflection member, and at least a low beam. The second reflection member is configured to be switched between a position and a third position that forms an alignment pattern of a third irradiation mode. And a first optical member that receives light reflected by the first reflecting member or the second reflecting member located at the first position or the second position when the beam is high, and emits the light forward of the vehicle; And a second optical member that receives light reflected by the second reflecting member located at the third position in the third irradiation mode and emits the light to the front of the vehicle.

  According to this configuration, the second reflecting member that switches between the low beam alignment pattern and the high beam alignment pattern by switching the position between the first position and the second position is further moved to the third position in the third irradiation mode. Can be switched. Then, the light reflected by the second reflecting member at the third position enters the second optical member and is emitted forward of the vehicle through the second optical member.

  As described above, in the configuration in which the low beam and the high beam are switched by switching the position of the second reflecting member, the second reflecting member can be further switched to the third position, and the light reflected by the second reflecting member at the third position can be switched. By further providing the second optical member that emits to the front of the vehicle, the third irradiation mode other than the high beam and the low beam can be realized while suppressing an increase in the number of components.

  The vehicular headlamp may further include a light blocking portion that blocks a part of light reflected by the first reflecting member when the second reflecting member is located at the third position.

  According to this configuration, in the third irradiation mode, the light amount is reduced by the light shielding portion. This configuration is effective when the third irradiation mode requires less light than the low beam and the high beam. For example, when the third irradiation mode is daytime lighting, the purpose of lighting is to make the other person recognize the host vehicle rather than to ensure the forward visibility. Therefore, the amount of light required for daytime lighting is less than that of the low beam and the high beam. By providing the light shielding portion, the amount of light can be reduced in the third irradiation mode.

  Further, the light shielding portion is configured integrally with the second reflecting member, and shields part of the light reflected by the first reflecting member when the second reflecting member is located at the third position. It may be located at a light shielding position.

  According to this configuration, the light shielding portion moves integrally with the second reflecting member, and moves to the light shielding position when the second reflecting member moves to the third position. Therefore, it is not necessary to provide a dedicated drive mechanism for driving only the light shielding portion, and the number of parts can be reduced.

  Further, when the second reflecting member is located at the third position, a part of the light reflected by the first reflecting member enters the first optical member without being reflected by the second reflecting member, The alignment pattern of the third irradiation mode may be formed by the light emitted from the first optical member and the light emitted from the second optical member.

  According to this configuration, the alignment pattern in the third irradiation mode is formed by combining light emitted through the first optical member and light emitted through the second optical member. Therefore, the degree of freedom of the alignment pattern is improved and a desired alignment pattern can be easily realized.

  The first reflecting member includes a first reflecting surface that reflects light from the light source toward the first optical member when the second reflecting member is positioned at the third position, and the second reflecting member. You may make it have a 2nd reflective surface which reflects the light from the said light source toward this 2nd reflective member when a member is located in the said 3rd position.

  According to this configuration, by providing the first reflecting member with two reflecting surfaces, when the second reflecting member is located at the third position, light is directed toward each of the first optical member and the second reflecting member. Can be reflected. That is, the structure which guides the light from the light source to each of the first optical member and the second reflecting member can be easily realized.

  The first optical member may be a lens, and the second optical member may be a reflector.

  Further, the light source may be configured such that the light emission amount is reduced as compared with the high beam and the low beam in the third irradiation mode.

  This configuration is effective when the third irradiation mode requires less light than the low beam and the high beam, for example, lighting in the daytime.

  According to the vehicle headlamp, the third irradiation mode other than the high beam and the low beam can be realized while suppressing an increase in the number of components.

  Hereinafter, exemplary embodiments will be described in detail with reference to the drawings.

  FIG. 1 shows a cross-sectional view of a vehicle headlamp 100. FIG. 2 shows a schematic front view of the vehicle headlamp 100.

  A vehicle headlamp (hereinafter, also simply referred to as “headlamp”) 100 is configured to tilt with a light source module 10 that emits light and a first reflector 20 that reflects light from the light source module 10. The movable mirror 30 that reflects the light reflected by the first reflector 20, the lens 40 that emits the light reflected by the first reflector 20 or the movable mirror 30 to the front of the vehicle, and the light reflected by the movable mirror 30 to the front of the vehicle A second reflector 50 that emits light, a drive motor 60 that drives the movable mirror 30, and a heat sink 70 that promotes heat dissipation of the vehicle headlamp 100 are provided to irradiate the front of the vehicle. The headlamp 100 is configured to be switchable between a low beam, a high beam, and daytime lighting. Since daytime lighting is lighting for improving visibility to allow others to recognize the host vehicle rather than ensuring visibility in front of the vehicle, the luminous intensity is suppressed as compared with the low beam and the high beam. Daytime lighting is an example of a third irradiation mode. Hereinafter, for convenience of explanation, front and rear, left and right, and top and bottom of the vehicle will be described as front and back, left and right, and top and bottom of the headlamp 100.

  The light source module 10 includes a light emitting element 11 such as an LED. The light emitting element 11 is a point light source and emits light radially. The light emitting element 11 is located on the optical axis L of the lens 40. The light source module 10 is an example of a light source.

  The 1st reflector 20 is arrange | positioned so that the light source module 10 may be covered from upper direction, and the light from the light source module 10 is reflected. The first reflector 20 has a first reflecting surface 21 and a second reflecting surface 22 provided in front of the first reflecting surface 21. As will be described in detail later, the light reflected by the first reflecting surface 21 is used for low beam, high beam, and daytime lighting. The light reflected by the second reflecting surface 22 is used during high beam and daytime lighting.

  The first and second reflecting surfaces 21 and 22 are substantially formed as spheroidal surfaces. Of the two focal points of the first reflecting surface 21, the front focal point is a first front focal point a1, and the rear focal point is a first rear focal point a2. Of the two focal points of the second reflecting surface 22, the front focal point is the second front focal point b1, and the rear focal point is the second rear focal point b2. The position of the first rear focal point a2 and the position of the second rear focal point b2 are the same, and are both in the vicinity of the light emitting element 11 and on the optical axis L of the lens 40. The first front focal point a1 is located on the optical axis L of the lens 40 in front of the first rear focal point a2. The second front focal point b1 is located in front of the second rear focal point b2 and below the optical axis L of the lens 40. The first reflector 20 is an example of a first reflecting member.

  The lens 40 emits light from the light source module 10 forward. As will be described in detail later, the light reflected by the first reflector 20 or the movable mirror 30 in the low beam and the high beam is incident on the lens 40, and the light is emitted forward. The lens 40 is a plano-convex lens having a convex front lens surface and a flat rear lens surface. The optical axis L of the lens 40 extends in the front-rear direction and coincides with the long axis of the first reflecting surface 21. Further, the focal point c1 on the rear side of the lens 40 coincides with the first front focal point a1 of the first reflecting surface 21. The lens 40 is held by a lens holder 41. The lens is an example of a first optical member.

  The movable mirror 30 is located in front of the light source module 10 and below the first reflector 20. The movable mirror 30 has a main body portion 31 and a light shielding portion 32. The movable mirror 30 is an example of a second reflecting member.

  The main body 31 has a flat plate shape, and a reflective surface 31 a is formed on the surface facing the first reflector 20. The front end edge of the main body 31 is not shown in the figure, but is curved rearward in a convex shape. The light shielding part 32 has a flat plate shape and is integrally connected to the rear end of the main body part 31. The light shielding part 32 is inclined with respect to the main body part 31, and the movable mirror 30 has a bent shape as a whole. The movable mirror 30 is provided with a rotating shaft 33 at a connecting portion between the main body 31 and the light shielding portion 32. The rotating shaft 33 extends horizontally in the left-right direction. The movable mirror 30 is configured to be tiltable about the rotation axis X. The movable mirror 30 is driven by a drive motor 60.

  As will be described in detail later, the movable mirror 30 configured as described above has a first position for forming a low beam alignment pattern, a second position for forming a high beam alignment pattern, and a first position for forming an alignment pattern for daytime lighting. It is configured to move to 3 positions. The light shielding part 32 is located at a light shielding position where a part of the reflected light from the first reflecting surface 21 of the first reflector 20 is shielded when the movable mirror 30 is located at the third position.

  The second reflector 50 is used during daytime lighting, and the light reflected by the movable mirror 30 enters and reflects the light forward. The second reflector 50 is disposed below the lens 40. The 2nd reflector 50 has the reflective surface 51 formed in the rotation paraboloid substantially. Strictly speaking, the reflection surface 51 is a free-form surface close to a paraboloid of revolution so that the light reflected by the reflection surface 51 is emitted while spreading forward. Further, the focal point d1 when the reflecting surface 51 is approximated to a rotating paraboloid substantially coincides with the second front focal point b1 of the second reflecting surface 22. The second reflector 50 is an example of a second optical member.

  Next, the operation of the headlamp 100 configured as described above will be described. FIG. 3 shows a cross-sectional view of the headlamp 100 in the case of a low beam. FIG. 4 shows an alignment pattern in the case of a low beam. FIG. 5 shows a cross-sectional view of the headlamp 100 in the case of a high beam. FIG. 6 shows an alignment pattern for a high beam. FIG. 7 shows a cross-sectional view of the headlamp 100 during daytime lighting. FIG. 8 shows an alignment pattern formed by the lens 40 when it is lit in the daytime. FIG. 9 shows an alignment pattern formed by the second reflector 50 when it is lit in the daytime. FIG. 10 shows an orientation pattern at daytime lighting. The isoluminous lines in FIGS. 4, 6, 8 to 10 are drawn for the purpose of representing the shape of the alignment pattern, and the range of the isoluminous lines varies from figure to figure. That is, just because the size of the alignment patterns indicated by the isophotometric lines is the same, the intensity of the alignment patterns is not the same.

<Low beam>
When the headlamp 100 is a low beam, the movable mirror 30 is located at the first position as shown in FIG. In the first position, the reflecting surface 31a of the movable mirror 30 is in a substantially horizontal state, and the optical axis L of the lens 40 is located in the reflecting surface 31a. The first front focal point a1 of the first reflecting surface 21 is located at the front edge of the reflecting surface 31a. The light shielding portion 32 of the movable mirror 30 is located below the optical axis L and at a position where the reflected light from the first reflecting surface 21 is not blocked.

  In this state, when light is emitted from the light source module 10, a part of the light enters the first reflecting surface 21 of the first reflector 20. Since the light emitting element 11 is located in the vicinity of the first rear focal point a2, the light emitted from the light emitting element 11 is reflected by the first reflecting surface 21 and condensed toward the first front focal point a1. Go. Part of the light traveling toward the first front focal point a <b> 1 is reflected by the movable mirror 30 and enters the lens 40, and the rest enters the lens 40 without hitting the movable mirror 30. The light incident on the lens 40 is emitted forward. Note that another part of the light emitted from the light source module 10 enters the second reflecting surface 22 of the first reflector 20, but the light is then scattered and hardly emitted forward through the lens 40. .

  In the low beam alignment pattern formed in this way, as shown in FIG. 4, a horizontal cut line that substantially coincides with the horizontal reference line is formed, and an alignment pattern is formed below the cut line. .

<High beam>
When the headlamp 100 is a high beam, the movable mirror 30 is located at the second position as shown in FIG. The second position is a position where the movable mirror 30 is tilted by a predetermined angle from the first position so that the front end portion is lowered from the first position. In the second position, the movable mirror 30 is located at a position where the first front focal point a1 and the second front focal point b1 are symmetrical with respect to the reflective surface 31a. The light shielding portion 32 of the movable mirror 30 is substantially horizontal and substantially parallel to the optical axis L, and is located at a position where the reflected light from the first reflecting surface 21 is not blocked.

  In this state, when light is emitted from the light source module 10, part of the light is incident on the first reflecting surface of the first reflector 20. The light is reflected by the first reflecting surface 21 and condensed toward the first front focal point a1 of the first reflecting surface 21. This light converges at the first front focal point a 1 and then diverges and enters the lens 40. Further, another part of the light emitted from the light source module 10 enters the second reflecting surface 22 of the first reflector 20. The light is reflected by the second reflecting surface 22 and condensed toward the second front focal point b1 of the second reflecting surface 22. Since the movable mirror 30 is located between the second reflecting surface 22 and the second front focal point b <b> 1, the light is reflected by the movable mirror 30. Since the reflective surface 31a of the movable mirror 30 is a symmetrical surface of the first front focal point a1 and the second front focal point b1, the light reflected by the reflective surface 31a is condensed toward the first front focal point a1. To go. The light converges at the first front focal point a <b> 1, then diverges, and enters the lens 40.

  Thus, in the case of a high beam, a part of the light emitted from the light source module 10 is reflected by the first reflecting surface 21 toward the lens 40, and another part is reflected by the second reflecting surface 22. It goes to the movable mirror 30, is further reflected by the movable mirror 30, and goes to the lens 40.

  In the alignment pattern of the high beam formed in this way, as shown in FIG. 6, an alignment pattern that extends widely above and below the horizontal reference line is formed. Since the high beam alignment pattern is formed not only by the light reflected by the first reflecting surface 21 of the first reflector 20, but also by the light reflected by the second reflecting surface 22, the luminous intensity compared to the low beam alignment pattern. Is expensive.

<Lit during daytime>
When the headlamp 100 is lit in the daytime, the movable mirror 30 is located at the third position as shown in FIG. The third position is a position where the movable mirror 30 is tilted by a predetermined angle from the second position so that the front end portion is further lowered from the second position. In the third position, the second front focal point b1 is located on the reflecting surface 31a. At this time, the light shielding portion 32 is in a state of protruding upward from the optical axis L.

  In this state, when light is emitted from the light source module 10, part of the light is incident on the first reflecting surface of the first reflector 20. The light is reflected by the first reflecting surface 21 and condensed toward the first front focal point a1 of the first reflecting surface 21. This light converges at the first front focal point a 1 and then diverges and enters the lens 40. Thus, the light reflected by the first reflecting surface 21 of the first reflector 20 enters the lens 40 without being reflected by the movable mirror 30. Here, since the light shielding portion 32 of the movable mirror 30 protrudes above the optical axis L, a part of the reflected light from the first reflecting surface 21 is blocked by the light shielding portion 32. For this reason, the amount of light that is reflected by the first reflecting surface 21 and incident on the lens 40 is reduced compared to when the movable mirror 30 is positioned at the second position.

  Further, another part of the light emitted from the light source module 10 enters the second reflecting surface 22 of the first reflector 20. The light is reflected by the second reflecting surface 22 and condensed toward the second front focal point b1 of the second reflecting surface 22. The light traveling toward the second front focal point b1 is reflected by the movable mirror 30 and enters the second reflector 50. Since the second front focal point b1 substantially coincides with the focal point d1 of the paraboloid of the reflecting surface 51, the light incident on the second reflector 50 from the second front focal point b1 is reflected forward.

  Thus, during daytime lighting, a part of the light emitted from the light source module 10 is reflected by the first reflecting surface 21 toward the lens 40, and another part is reflected by the second reflecting surface 22. To the movable mirror 30 and further reflected by the movable mirror 30 toward the second reflector 50.

  Thus, the alignment pattern for daytime lighting is a combination of the alignment pattern by the light passing through the lens 40 as shown in FIG. 8 and the alignment pattern by the light reflected by the second reflector 50 as shown in FIG. An orientation pattern as shown in FIG.

  Since the light incident on the lens 40 is incident on the lower half of the lens 40, the alignment pattern by the light passing through the lens 40 is formed below the horizontal reference plane. Here, of the light reflected by the first reflecting surface 21, the light traveling toward the vicinity of the center of the lens 40 is shielded by the light shielding portion 32, so that no light is emitted from the portion corresponding to the center of the lens 40.

  On the other hand, the alignment pattern by the light reflected by the second reflector 50 is formed substantially above the horizontal reference plane. In this orientation pattern, a pattern is also formed at a portion corresponding to the center of the lens 40. That is, the light amount of the center portion that is insufficient in the alignment pattern by the light passing through the lens 40 is compensated by the light reflected by the second reflector 50.

  As a result of synthesizing the two alignment patterns, the alignment pattern for daytime lighting has a shape that greatly expands vertically. Thus, since the alignment pattern for daytime lighting is realized by the combination of the light irradiated through the lens 40 and the light irradiated through the second reflector 50, the degree of freedom of the alignment pattern is improved. It becomes easy to realize a desired alignment pattern. In the daytime lighting, the light intensity is reduced by the light shielding portion 32 of the movable mirror 30, so the luminous intensity of the entire alignment pattern is lower than that of the high beam and the low beam.

  As described above, the headlamp 100 forms the light source module 10, the first reflector 20 that reflects the light from the light source module 10, the first position where the low beam alignment pattern is formed, and the high beam alignment pattern. The position can be switched between a second position and a third position that forms an orientation pattern for daytime lighting, a movable mirror 30 that reflects light reflected by the first reflector 20, and at least a low beam and a high beam Sometimes the light reflected by the first reflector 20 or the movable mirror 30 located at the first position or the second position is incident, and the lens 40 emits the light to the front of the vehicle, and is located at the third position during daytime lighting. And a second reflector that makes the light reflected by the movable mirror 30 incident and emit the light forward of the vehicle.

  According to this configuration, the movable mirror 30 that switches between the low beam alignment pattern and the high beam alignment pattern by switching the position between the first position and the second position is further switched to the third position during daytime lighting. Then, the light reflected by the movable mirror 30 at the third position is incident on the second reflector 50 different from the lens 40 on which the light is incident in the case of the low beam or the high beam, and is emitted forward of the vehicle through the second reflector. To do.

  As described above, in the configuration in which the low beam and the high beam are switched by switching the position of the movable mirror 30, the movable mirror 30 can be further switched to the third position, and the light reflected by the movable mirror 30 at the third position is forward of the vehicle. By further providing the second reflector 50 that emits light, a third irradiation mode other than the high beam and the low beam, that is, lighting in the daytime can be realized while suppressing an increase in the number of components.

  The first reflector 20 includes a first reflecting surface 21 that reflects light from the light source module 10 toward the lens 40 when the movable mirror 30 is located at the third position, and the movable mirror 30 at the third position. It has the 2nd reflective surface 22 which reflects the light from the light source module 10 toward the movable mirror 30, when it locates.

  According to this configuration, by providing two reflecting surfaces on the first reflector 20, it is possible to reflect light toward the lens 40 and the movable mirror 30. That is, a configuration for guiding the light from the light source module 10 to each of the lens 40 and the movable mirror 30 can be easily realized. The first reflecting surface 21 and the second reflecting surface 22 are reflecting surfaces used for forming a high beam alignment pattern. In this way, by changing the position of the movable mirror 30, it is possible to realize an alignment pattern for daytime lighting by using two reflecting surfaces for forming a high beam alignment pattern.

  Furthermore, the headlamp 100 includes a light shielding unit 32 that reduces the amount of light when the movable mirror 30 is located at the third position.

  As a result, the amount of light can be reduced during daytime lighting compared to low beam and high beam.

  Further, the light shielding portion 32 is configured integrally with the movable mirror 30 and is located at a light shielding position where a part of light reflected by the first reflector 20 is shielded when the movable mirror 30 is located at the third position. .

  According to this configuration, when the movable mirror 30 moves to the third position in order to perform daytime lighting, the light shielding unit 32 also automatically moves to the light shielding position. Therefore, it is not necessary to provide a dedicated drive mechanism for driving only the light shielding portion 32, and the number of parts can be reduced.

<< Other Embodiments >>
As described above, the embodiment has been described as an example of the technique disclosed in the present application. However, the technology in the present disclosure is not limited to this, and can also be applied to an embodiment in which changes, replacements, additions, omissions, and the like are appropriately performed. Moreover, it is also possible to combine each component demonstrated by the said embodiment and it can also be set as new embodiment. In addition, among the components described in the accompanying drawings and detailed description, not only the components essential for solving the problem, but also the components not essential for solving the problem in order to exemplify the above technique May also be included. Therefore, it should not be immediately recognized that these non-essential components are essential as those non-essential components are described in the accompanying drawings and detailed description.

  About the said embodiment, it is good also as following structures.

  For example, although the 1st reflector 20 has the 1st reflective surface 21 and the 2nd reflective surface 22, it is not restricted to this. The first reflector 20 may have a reflective surface other than the first reflective surface 21 and the second reflective surface 22. For example, the first reflecting surface 21 and the second reflecting surface 22 are shared during high beam and daytime lighting, but separate reflecting surfaces may be provided for high beam and daytime lighting. Moreover, the 1st reflective surface 21 and the 2nd reflective surface 22 may be provided in another member.

  Although the light-shielding part 32 is provided in the movable mirror 30, the light-shielding part 32 may be omitted. In that case, the light shielding unit 32 may be provided separately from the movable mirror 30. In that case, the light shielding part 32 may be positioned at the light shielding position at least when the movable mirror 30 is located at the third position.

  In addition, the movable mirror 30 is configured to tilt around the rotation axis 33, but the movement of the movable mirror 30 is not limited to tilting and can be moved to a position for realizing the low beam, the high beam, and the third irradiation mode. As long as an arbitrary movement method can be applied.

  The lens 40 is only an example of a first optical member, and any optical member can be adopted as long as it can emit light forward. The second reflector 50 is merely an example of the second optical member, and any optical member such as a lens or a prism can be adopted as long as it can emit light forward. Furthermore, the first optical member and the second optical member may be formed integrally. For example, a central portion of a single lens may function as a first optical member, and a portion that functions as a second optical member may be provided on the outer peripheral side of the central portion.

  The output of the light source module 10, that is, the light emission amount, may not be uniform in the low beam, high beam, and third irradiation modes. The light emission amount of the light source module 10 may be configured to be adjusted according to each mode. For example, the light source module 10 may be configured such that the light emission amount is reduced as compared with the high beam and the low beam in the third irradiation mode. This configuration is effective when the third irradiation mode requires less light than the low beam and the high beam, for example, lighting in the daytime.

  Daytime lighting is merely an example of the third irradiation mode, and may be other than the third irradiation mode daytime lighting. In other words, any irradiation mode can be adopted as the third irradiation mode as long as the alignment mode is different from that of the low beam and the high beam.

  As described above, the technique disclosed herein is useful for a vehicle headlamp.
