Description

  The present invention relates to a vehicle headlamp used, for example, as a headlamp or an auxiliary headlamp provided at the front of an automobile.

2. Description of the Related Art Conventionally, a so-called projector-type automotive headlamp includes a bulb as a light source bulb, a reflective surface that reflects light from the bulb forward, a projection lens that focuses the light from the bulb or the reflective surface, and a bulb. And a shutter for forming a so-called cut-off line disposed in the optical path from the projection lens to the projection lens.
Here, the bulb is disposed forward so that the central axis thereof coincides with the optical axis of the projection lens extending substantially horizontally toward the front.

According to the headlamp having such a configuration, the light emitted from the bulb is reflected directly or reflected by the reflecting surface, enters the projection lens, and is focused forward by the projection lens. The
At that time, a part of the light incident on the projection lens is blocked by the shutter, so that a desired light distribution characteristic is obtained such that the irradiation distance is shortened on the oncoming lane side so as not to give a dazzling light to the oncoming vehicle. A so-called passing beam is formed.

  However, in the headlamp having such a configuration, as described above, since the bulb is disposed forward, the entire length of the entire lamp in the front-rear direction becomes relatively long, and the mounting space for the vehicle body of the automobile Increases, and the degree of freedom in mounting is small, which is a restriction on the vehicle body design.

On the other hand, in Patent Document 1 and Patent Document 2, there is a vehicle headlamp in which a bulb is inserted (laterally) from the side of the optical axis and further disposed below the optical axis of the projection lens. It is disclosed.
According to such a structure, since the bulb | bulb with fixed length is arrange | positioned sideways, the full length of a lamp can be shortened and it can be comprised small.

  Further, in the vehicle headlamp according to Patent Document 1, a movable shutter is provided, and this shutter is inserted into the optical path to the projection lens, thereby forming a cut-off line by the shutter edge, thereby arranging the passing beam. The light distribution characteristic of the traveling beam is obtained by obtaining the light characteristic and retracting the shutter from the optical path.

Further, in the vehicle headlamp according to Patent Document 2, light other than the main light distribution irradiated forward from the light source bulb through the reflecting surface and the projection lens is directed toward the vehicle front by the additional reflector without passing through the projection lens. By reflecting the light, light from the light source bulb is effectively used to obtain light distribution characteristics with better visibility.
JP 2005-293984 A Japanese Patent Laying-Open No. 2005-276761

By the way, the bulb generally has a light emission characteristic that gives the maximum luminous intensity near the central axis.
On the other hand, in the projector-type vehicle headlamps disclosed in Patent Document 1 and Patent Document 2, the light emission center of the bulb is arranged so as to be located immediately below the optical axis, and the light is emitted from the bulb in the direction of the central axis. Thus, the light reflected by the optical axis side region of the reflecting surface is transmitted through the projection lens and then emitted to the side region of the light distribution pattern, that is, a so-called diffusion region.
For this reason, since the light which gives the maximum luminous intensity of the bulb is not irradiated toward the vicinity of the front light distribution center, the maximum luminous intensity near the center in the light distribution pattern is lowered.
Therefore, compared with a normal projector-type vehicle headlamp in which conventional light source bulbs are arranged along the optical axis direction, the amount of light emitted toward the front light distribution center is reduced and the maximum altitude is increased. Will fall.

  Further, in the vehicle headlamp according to Patent Document 1, the passing beam and the traveling beam are switched by a movable shutter. However, since the maximum luminous intensity is insufficient by inserting a light source in a lateral direction, a single light source bulb, It has been difficult to sufficiently satisfy the light distribution characteristics of both the passing beam and the traveling beam by the reflecting surface and the projection lens.

  On the other hand, in the vehicle headlamp according to Patent Document 2, light from the light source bulb is effectively used by the additional reflector, but the light reflected by the additional reflector irradiates the outer edge of the light distribution pattern. Therefore, since it is not configured to increase the luminous intensity in the vicinity of the center of the light distribution characteristic, similarly, the amount of light emitted toward the front decreases, and the maximum altitude decreases.

  In view of the above, the present invention is a projector-type vehicle headlamp of a bulb lateral type that increases the maximum luminous intensity near the center of the light distribution pattern and increases the total luminous flux of the irradiated light with a simple configuration. The purpose is to provide.

  According to the configuration of the present invention, the above object is achieved by a convex projection lens disposed on an optical axis extending horizontally in the irradiation direction, and substantially orthogonal to the optical axis behind the focal position on the rear side of the projection lens. A light source bulb arranged in a direction, a main reflector that reflects the light emitted from the light source bulb and focuses the light toward the focal position on the rear side in the irradiation direction of the projection lens, and the light emitted from the light source bulb. Of these, a first reflecting surface that reflects light emitted upward slightly forwardly and a second reflecting surface that reflects light from the first reflecting surface toward the vicinity of the light distribution center forward in the irradiation direction. A sub-reflector having a first light-shielding portion that is disposed in the vicinity of the rear focal position of the projection lens and shields at least part of the optical path to the projection lens; and a second reflector from the first reflecting surface of the sub-reflector. Of the light path reflected by the reflecting surface A shutter having a second light-shielding portion that shields at least a part of the shutter, and the shutter has a cutoff for the beam that the first light-shielding portion passes on the optical path from the main reflector to the projection lens. An insertion position where the second light-shielding portion shields at least part of an optical path reflected from the first reflecting surface of the sub-reflector to the second reflecting surface; and a second position of the projection lens and the sub-reflector This is achieved by a vehicular headlamp that moves between a retracted position that releases the optical path of the reflecting surface.

  The vehicle lamp according to the present invention preferably forms a passing light distribution when the shutter is in the insertion position, and forms a traveling light distribution when the shutter is in the retracted position.

  In the vehicle lamp according to the present invention, preferably, the shutter has an opening in a part of the second light shielding portion, and when the second light shielding portion is in the insertion position, the second light shielding portion At least a part of the optical path reflected from the first reflecting surface to the second reflecting surface of the sub-reflector is shielded, and when in the retracted position, the optical path passes through the opening.

  In the vehicular lamp according to the present invention, preferably, when the second light-shielding portion is in the insertion position, the second light-shielding portion reflects the second reflector from the first reflecting surface to the second reflecting surface. The optical path is shielded, and irradiation is performed only from the projection lens.

According to the above configuration, the light emitted from the light source bulb is reflected directly or by the main reflector and is focused toward the second focal position, that is, the focal position on the rear side of the projection lens. It is irradiated toward the front through.
Further, the light emitted from the light source bulb to the upper front side and incident on the sub-reflector is reflected by the sub-reflector and irradiated forward.

  Here, at the time of traveling beam, the light reflected by the sub-reflector passes through the opening without being blocked by the shutter, and is irradiated toward the front center as it is because the shutter moves to the retracted position. Will be. In the present invention, in addition to the main light distribution pattern by the main reflector, the spot light distribution pattern by the sub reflector is irradiated toward the vicinity of the center by the light reflected by the main reflector and the sub reflector. As a result, the light intensity near the center of the present invention is increased, and an optimal light distribution pattern for the traveling beam can be obtained.

On the other hand, at the time of the low beam, since the shutter is moved to the insertion position, the light reflected by the sub-reflector is blocked by the shutter, so that at least a part of the sub-reflector is directed forward. Not irradiated.
Therefore, only the light reflected by the main reflector is irradiated forward through the projection lens, and at that time, a cut-off line is formed by the shutter, so that a light distribution pattern suitable for the low beam can be obtained. .

Here, since the light source bulb is arranged substantially horizontally, the entire lamp of the vehicle headlamp can be configured to be relatively short.
In addition, when the shutter is in the retracted position, the light reflected by the sub-reflector increases the luminous intensity near the center of the light distribution pattern, and sufficient luminous intensity is obtained as a traveling beam.

  The sub-reflector reflects the light emitted from the light source bulb in a slightly upward direction forward from the light source bulb and reflected by the first reflective surface and the first reflective surface. And a second reflecting surface that reflects forward light below the shutter toward the front, from the light source bulb by the first reflecting surface and the second reflecting surface of the sub-reflector. By reflecting light in two stages, the sub-reflector can be made relatively small.

The first reflecting surface of the sub-reflector is formed as an elliptical reflecting surface having a first focal point near the light source bulb and having a second focal point near the center of the opening at the retracted position of the shutter. And when the second reflecting surface of the sub-reflector is formed as a parabolic reflecting surface having a focal point near the second focal point of the first reflecting surface, After the light reflected by the reflective surface is focused near the second focal point, the light is reflected by the second reflective surface and irradiated forward.
Therefore, in the vicinity of the second focal point of the first reflecting surface of the sub-reflector where the light is most focused, the opening of the shutter blocks or passes this light, so that the opening is almost the same as the image of the light source bulb. Since the same size is sufficient, the size of the shutter can be relatively small, and the amount of movement of the shutter for switching between blocking and passing can be reduced, and the entire shutter can be downsized.

  Thus, according to the present invention, in the projector-type vehicle headlamp in which the light source bulb is disposed sideways, the auxiliary reflector is added, and the light from the light source bulb is irradiated forward by the auxiliary reflector. Thus, light from a light source bulb that has not been conventionally used is irradiated near the center of the light distribution pattern of the traveling beam.

As a result, at the time of the traveling beam, the use efficiency of light from the light source bulb is improved by moving the shutter to the retracted position and increasing the luminous intensity near the center of the light distribution pattern of the traveling beam by the reflected light from the sub-reflector. The maximum luminous intensity near the center in the light distribution pattern can be increased, and the total luminous flux emitted from one lamp body is increased.
In the case of a passing beam, the shutter moves to the insertion position, thereby blocking the reflected light from the first reflecting surface of the sub-reflector and forming a cutoff line in the reflected light from the main reflector. A light distribution pattern suitable for a passing beam can be obtained.

  Therefore, according to the present invention, the light distribution pattern, the luminous intensity near the center, and the total luminous flux can be optimized with respect to both the traveling beam and the low beam by one lamp body (light source bulb, main reflector and projection lens). .

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to FIGS.
The embodiments described below are preferable specific examples of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention particularly limits the present invention in the following description. As long as there is no description of the effect, it is not restricted to these aspects.

FIG. 1 shows the configuration of an embodiment of a vehicular lamp according to the present invention.
In FIG. 1, a vehicular lamp 10 is a headlight of an automobile, and includes a bulb 11 as a light source bulb as its constituent elements, a main reflector 12 that reflects light from the bulb 11 forward, and a bulb. 11 includes a projection lens 13 disposed in front of 11, a shutter 14, and a sub reflector 15 disposed above and below the bulb 11.

The bulb 11 is a bulb generally used for an automobile headlamp or an auxiliary headlamp. For example, a bulb such as an incandescent bulb, a halogen bulb or a metal halide lamp is used as a bulb (not shown). Is fixed and held, and power is supplied.
In this case, the bulb 11 further extends in a direction perpendicular to the optical axis O of the projection lens 13 (hereinafter also referred to as “laterally”) and has a tip extending toward the outer side of the vehicle body. As described above, the optical axis O is shifted downward.

The main reflector 12 is disposed behind the bulb 11, and is formed in a concave shape toward the front L1 so as to reflect the light emitted from the bulb 11 to the rear side toward the front. The focal point position F1 is located in the vicinity of the light emission center 11a of the bulb 11, and the second focal point position F2 is formed on the elliptical reflecting surface so as to be located on the optical axis O on the front side.
Here, the elliptical reflecting surface includes not only a spheroid and an elliptic cylinder but also a free-form surface based on an ellipsoid.
Thereby, the light emitted backward from the bulb 11 is reflected by the main reflector 12 and proceeds toward the focal position on the rear side of the projection lens 13, and further passes through the projection lens 13 via the shutter 14 and forwards. It comes out toward the direction.

  The projection lens 13 is composed of a convex lens, and is arranged such that the focal point on the light source side is located near the second focal position F2 of the main reflector 12 on the optical axis O. ing.

  The shutter 14 is made of an opaque material and can move between an insertion position (shown in FIG. 2) and a retracted position (shown in FIG. 3) as shown in FIG. It is configured.

2, the upper edge 14a of the shutter 14 at the insertion position shown in FIG. 2 is positioned at the focal position on the light source side of the projection lens 13, and forms, for example, a cut-off line in the light distribution pattern of the passing beam. It is supposed to be.
Further, the shutter 14 has an upper edge 14 a that opens the optical path of the projection lens 13 at the retracted position indicated by a dotted line in FIG. 3, and reflects the light that is reflected by the main reflector 12 and enters the projection lens 13. It does not interfere.

Further, the shutter 14 is a light-shielding portion 14b that extends substantially horizontally below the pivot shaft 14d and substantially perpendicular to the optical axis from the first reflecting surface to the second reflecting surface of the sub-reflector 15. The light shielding portion 14b is provided with an opening portion 14c substantially at the center thereof.
The light shielding portion 14b shields the optical path from the first reflecting surface 15a of the sub reflector 15 to the second reflecting surface 15b when the shutter 14 is in the insertion position.
On the other hand, when the shutter 14 is in the retracted position, the light shielding portion 14b is retracted from the optical path and opens the optical path from the first reflecting surface 15a to the second reflecting surface 15b of the sub-reflector 15. .

  In the case shown in the drawing, the shutter 14 is supported so as to be swingable about a rotating shaft 14d, and the above-described insertion position and retraction position are set by appropriate driving means such as a solenoid and a motor as moving means. Can be moved between.

  The sub-reflector 15 is arranged above and below the shutter 14 in front of the irradiation direction of the light L1 of the bulb 11 and so as not to interfere with light incident on the projection lens 13 from the bulb 11 or the main reflector 12. An upper first reflecting surface 15a and a lower second reflecting surface 15b are formed.

Here, the first reflecting surface 15a is formed in a concave shape rearward and downward so as to reflect light emitted upward from the bulb 11 forward in the L1 direction, and has a first focus. The elliptical reflecting surface is configured such that the position F1 is located near the light emission center 11a of the bulb 11 and the second focal position F3 is located near the opening 14c at the insertion position of the shutter 14. .
Thereby, the light emitted from the bulb 11 to the upper front side in the L1 direction is reflected by the first reflecting surface 15a of the sub-reflector 15, converged toward the second focal position F3, and then reflected by the second reflection. The light enters the surface 15b.

On the other hand, the second reflecting surface 15b is disposed below the shutter 13, and receives the reflected light from the first reflecting surface 15a of the upper sub-reflector 15 toward the front center. Is formed in a concave shape toward the front in the L1 direction, the focal position thereof is located in the vicinity of the second focal position F3 of the first reflecting surface 15a, and the central axis is a straight line parallel to O. It is composed of a parabolic reflecting surface extending forward. Here, the parabolic reflecting surface includes not only a rotating parabolic surface but also a free curved surface based on a parabolic surface.
Thereby, the light reflected by the first reflecting surface 15a of the sub-reflector 15 and converged toward the second focal position F3 is reflected by the second reflecting surface 15b and toward the front center. It is irradiated as spot light distribution (light distribution condensed near the center).

  The vehicular lamp 10 according to the embodiment of the present invention is configured as described above. When the bulb 11 is supplied with power from the socket and emits light, a part of the light L1 emitted from the bulb 11 is shown in FIG. As shown in FIG. 1, the light is reflected directly or by the main reflector 12, proceeds toward the second focal point F 2, that is, near the focal position on the rear side of the projection lens 13, and is further focused by the projection lens 13 through the shutter 14. While irradiating forward.

Here, during the traveling beam, as shown in FIG. 2, the shutter 14 is brought to the retracted position by a moving means (not shown).
As a result, the light L2 emitted from the bulb 11 toward the upper front side is reflected by the first reflecting surface 15a of the sub-reflector 15 and converged toward the second reflecting surface 15b, so that the opening 14c of the shutter 14 is obtained. Then, the light is reflected by the second reflecting surface 15b and irradiated toward the front center.

At this time, the light L2 irradiated toward the front upper side is the center of the light distribution pattern with respect to the light distribution pattern formed by the light L1 reflected by the main reflector 12 and irradiated forward through the projection lens. The light is additionally irradiated in the vicinity as a spot light distribution.
Therefore, the sub-reflectors 15a and 15b can further increase the maximum luminous intensity near the center of the light distribution pattern of the traveling beam and increase the total luminous flux, thereby improving the distance visibility.

On the other hand, at the time of passing beam, as shown in FIG. 3, the shutter 14 is brought to the insertion position by moving means (not shown).
As a result, the upper edge 14a of the shutter 14 is enlarged and projected forward by the projection lens 13, whereby a cut-off line in the light distribution pattern is formed, and a light distribution pattern of a passing beam is obtained. .

The light L2 emitted from the bulb 11 toward the upper front side is reflected by the first reflecting surface 15a of the sub-reflector 15 and converges toward the second reflecting surface 15b. It will be interrupted by 14b. Therefore, the light L2 is not irradiated forward.
Thereby, based on the direct light from the bulb 11 and the light reflected by the main reflector 12, that is, the light L1, a light distribution pattern optimum for the passing beam is obtained.

In this case, the shutter 14 is moved between the retracted position and the insertion position by the moving means, thereby forming a cut-off line for the passing beam and blocking the optical path of the sub reflector 15 with a simple configuration. Thus, the number of parts can be reduced, and the part cost and assembly cost can be reduced.
At this time, the light L2 reflected by the first reflecting surface 15a of the sub-reflector 15 is converged in the vicinity of the opening 14c of the shutter 14, so that the opening 14c can be made small and the opening 14c and the shutter 14 can be reduced. Since the amount of movement between the insertion position and the retraction position is small, the shutter 14 and its moving mechanism can be made compact.

Therefore, the vehicular lamp 10 can be configured so that the entire length of the lamp can be shortened by arranging the bulb 11 in the lateral direction, and the amount of the main reflector 12 projecting in the lateral direction can be reduced, and the overall size can be reduced. Could be configured.
Further, the opening 14c of the shutter 14 is inserted into and removed from the optical path of the sub-reflector 15, so that the light intensity near the center of the light distribution pattern is switched and the maximum light intensity near the center at the time of the traveling beam is increased. The maximum luminous intensity near the center optimal for the beam and the passing beam is set, and the maximum luminous intensity near the center of the light distribution pattern at the time of the traveling beam can be sufficiently increased.

4 and 5 show the simulation results of the light distribution pattern by the vehicle headlamp 10 described above.
Here, FIG. 4 shows a light distribution pattern at the time of the passing beam.
In this case, the light distribution pattern is formed by light L <b> 1 reflected directly from the bulb 11 or by the main reflector 12 and emitted forward through the projection lens 14.
Accordingly, a cut-off line is formed by the upper edge 14a of the shutter 14 in substantially the same manner as in the conventional vehicle headlamp, and the maximum luminous intensity near the center is a light distribution pattern by only the light L1. Is set low.

On the other hand, FIG. 5 shows a light distribution pattern at the time of a traveling beam.
In this case, the light distribution pattern includes a light distribution pattern (see FIG. 5A) by the light L1 that is reflected directly from the bulb 11 or by the main reflector 12 and emitted forward through the projection lens 14, and the bulb 11. 5 is emitted toward the front upper side, reflected by the first reflecting surface 15a and the second reflecting surface 15b of the sub-reflector 15, and emitted by the light L2 near the front center (FIG. 5B ))).
Here, as shown in FIG. 5C, the total light distribution pattern by the light L1 + L2 described above is that the total luminous flux is increased and the maximum luminous intensity near the center of the light distribution pattern is sufficiently increased. I understand. Therefore, a luminous intensity near the center sufficient as a traveling beam can be obtained.

  In the embodiment described above, the sub-reflector 15 includes the first reflecting surface 15a and the second reflecting surface 15b disposed above and below the shutter 14, but is not limited thereto. If it is the structure which guides the light which does not contribute to the light distribution pattern by the main reflector 12 toward the front, you may be comprised from only one reflective surface or three or more reflective surfaces.

  In the above-described embodiment, the sub reflector 15 is disposed above and below the shutter 14, but may be configured by a single reflecting surface disposed only above or only below.

  As another embodiment of the present invention, as shown in FIGS. 6 and 7, of the sub-reflectors, the first reflecting surface 15a is formed of an elliptical free-form surface, and the second reflecting surface 15b is a simple paraboloid. The surface may be formed.

  In this case, not all the light to the second reflecting surface 15b is blocked by the shutter 14 during low beam, but only a part (for example, the front side of the focal point of the paraboloid) is blocked. By doing in this way, the vehicle headlamp 10 radiates | emits only the part corresponded in about the lower half of the high beam light distribution pattern ahead.

  By doing so, in the vehicle headlamp 10, the light distribution pattern as shown in FIG. 8 is added to the low beam light distribution pattern by the projection lens unit, and the amount of light at the time of low beam can be increased.

  In the present embodiment, the shape of the opening 14c may be any shape, for example, a hole having a predetermined shape, or simply shielding a part of the optical path to the second reflecting surface 15b. Anything is acceptable.

  The vehicle headlamp 10 according to the present invention is configured as an automotive headlamp. However, the present invention is not limited thereto, and the present invention can be applied to other types of vehicle lamps including auxiliary headlamps. Is possible.

  In this way, according to the present invention, a very good bulb horizontal projector that increases the maximum luminous intensity near the center of the light distribution pattern and increases the total luminous flux of the irradiated light with a simple configuration. A type vehicle headlamp may be provided.
