Description

  The present invention relates to a lamp suitable for a vehicular lamp such as a vehicle headlamp composed of a plurality of light source modules using small light sources such as LEDs.

With the recent improvement in luminous efficiency of white LEDs, various vehicle headlamps using white LEDs as light sources have been proposed.
The vehicle headlamp using such an LED has an output of about 1/30 to 1/20 compared to a conventional HID light source or the like. It is considered difficult to achieve the same output as an HID light source or the like.
Therefore, in order to construct a vehicle lamp such as a vehicle headlamp using LEDs, a plurality of (for example, about 10) small light source modules are arranged side by side. Here, each light source module is composed of at least one LED and optical elements such as a focusing lens and a reflector for converging light from the LED, and a light shielding member for forming a cutoff.

On the other hand, in recent years, in order to ensure a safe field of view such as when driving at night in a vehicle, the light irradiation range by the vehicle headlight is swung in conjunction with the steering angle of the steering, for example, when driving on a road curve So-called AFS lamps that improve the visibility of the vehicle traveling direction when turning right or left at intersections have been developed and partially put into practical use.
In order to swing the light irradiation range, a partial swivel system that changes the light distribution pattern by partially swinging a part of the optical system of the vehicle headlamp, the vehicle headlamp There is an entire swivel method that swings all of the optical system, and an additional light source method in which an auxiliary light source is added to swing the optical system of the auxiliary light source. As a practical method, an overall swivel method and an additional light source method are generally used.

By the way, when the AFS function is added to the above-described vehicular lamp using the LED, as shown in FIG. 11, a plurality of, in the illustrated case, five light source modules 1a, 1b, 1c, 1d, and 1e are provided. The vehicle headlamp 1 is configured by being integrated with each other, and this vehicle headlamp 1 is shown in FIG. 12 by driving means (not shown), for example, directly by a motor or via a gear, a link, a belt, or the like. As shown in the figure, a method of changing the light distribution pattern by the entire swivel method by swinging around one rotation axis 2 at the center can be considered.
In the case of such an overall swivel system, the drive mechanism of the conventional overall swivel system can be used as it is, so that the cost can be reduced by sharing parts.

However, in such an overall swivel type AFS lamp, the light source modules 1a,... Are arranged side by side in particular, so that the moment of inertia at the time of swinging is increased and the driving means also has a larger torque. Power source is required, and an operation space for smooth swinging is also increased.
In addition, such an arrangement restricts the overall design of the vehicle lamp, and the whole is rocked integrally. Therefore, the degree of freedom of deformation of the light distribution pattern due to the rocking is small, and in particular, LEDs are used. In this case, the advantage of downsizing can no longer be utilized.
In addition to the LED, such a problem also applies to a vehicle lamp in which a plurality of small light source modules using other types of small light emitting elements and other light sources are arranged side by side, or other lamps. There's a problem.

  In view of the above, the present invention is for vehicles such as a vehicle headlamp composed of a plurality of light source modules, which can be configured in a small size with a simple configuration and further has a high degree of freedom in design and light distribution pattern. It aims at providing the lamp suitable for a lamp.

According to the present invention, the above object is achieved by arranging a plurality of light source modules, which are composed of at least one small light source and an optical element such as a converging lens, and have an optical axis extending substantially horizontally in front in a horizontal direction at a predetermined interval. And when the plurality of light source modules are facing the front, the light distribution patterns of the respective light source modules are superimposed to function as a vehicle lamp that forms a light distribution pattern with sufficient brightness , Each light source module is supported so as to be swingable around a pivot axis substantially perpendicular to the optical axis and the alignment direction, and the light source modules are connected to each other via a link mechanism. a power transmission mechanism or one of the light source module is coupled to the link mechanism, the operation of the turning drive means, all the light sources via the link mechanism model Yuru is in Rukoto is swung at the same angle in the same direction about its pivot axis, the optical axis of each light source module, in a state of being substantially parallel to held together, rocking to the left or right direction toward the front This is achieved by a vehicular lamp characterized in that the light distribution pattern of each light source module is swung while being moved while being moved .

Further, according to the present invention, a plurality of light source modules each having an optical axis extending substantially horizontally in front are arranged at predetermined intervals in the lateral direction, and include at least one small light source and an optical element such as a focusing lens. It functions as a vehicular lamp that is arranged side by side and forms a light distribution pattern with sufficient brightness by superimposing the light distribution patterns of each light source module when the plurality of light source modules face the front. The light source modules are connected to each other through a link mechanism, and a connecting shaft to the power transmission mechanism or the link mechanism of one light source module and the turning drive means is defined by the turning shaft of each light source module. It is arranged at a position deviated from the plane to be connected and is connected to the link mechanism so that it can swing around a turning axis substantially perpendicular to its optical axis and alignment direction. By the operation of the turning drive means, all the light source modules are swung in the same direction around the turning axis via the link mechanism, and the light source module on the outside of the vehicle is changed to the light source module on the central axis. By oscillating at a large angle as it goes, the optical axis of each light source module is expanded in a relatively wide angle range and oscillated in either the left or right direction toward the front, whereby each light source module This is achieved by a vehicular lamp characterized in that a smooth light distribution pattern is obtained by slightly shifting the light distribution patterns .

In the vehicular lamp according to the present invention, preferably, the link mechanism has a number of engagement holes corresponding to the number of the light source modules, and the light source modules are connected by a connection point provided near the rear end. The engagement hole is connected to the link mechanism via the engagement hole, and the engagement hole is formed such that its length in the lateral direction becomes longer as it goes from the vehicle center side to the outside.

In the vehicular lamp according to the present invention, preferably, the turning drive means operates in conjunction with the operating state of the automobile .

In the vehicular lamp according to the present invention, preferably, the turning shaft of each light source module passes through the vicinity of the center of gravity of the light source module .

In the vehicle lamp according to the present invention, preferably, the distance from the connection point of each light source module to the link mechanism to the turning axis is constant .

In the vehicle lamp according to the present invention, preferably, the distance from the connecting point of each of the light source modules to the link mechanism to the turning axis is different from each other .

In the vehicular lamp according to the present invention , the connecting shaft to the link mechanism of the turning drive means is preferably arranged on the same plane as the plane defined by the turning shaft of each light source module .

  In the lamp according to the present invention, preferably, the link mechanism has a degree of freedom in the radial direction with respect to the pivot axis of the light source module at a connection point with each light source module.

  In the lamp according to the present invention, preferably, the turning drive means includes a plurality of drive shafts having different positions with respect to the link mechanism.

  In the lamp according to the present invention, preferably, the light source is an LED.

According to the above configuration, since the light source modules are connected to each other via the link mechanism, the optical axes of the light source modules are directed in substantially the same direction. Then, when the turning drive means is operated from this state, the turning drive force is transmitted from the turning drive means to each light source module via the link mechanism, and each light source module is swung around the turning axis in the same direction. The
Therefore, for example, when the turning driving means is operated in conjunction with the steering angle of the vehicle steering, the optical axis of each light source module is swung in the traveling direction of the vehicle, so-called AFS function. Can be realized.

In this case, since each light source module is configured in a small size, the moment of inertia when the light source module swings around the pivot axis becomes very small, and a relatively small and low torque swing drive means can be used. Each light source module can be swung around the pivot axis via the link mechanism, and each light source module is small in size, so that a small operation space is required for the vehicle. The entire lamp can be configured in a small size with a low cost and simple configuration.
Therefore, the degree of freedom in the design of the entire vehicle lamp and the arrangement of the light source modules is increased, and a more innovative vehicle lamp can be configured.

  When the lamp is a vehicular lamp and the turning drive means is operated in conjunction with the operating state of the automobile, for example, in conjunction with a steering mechanism, the turning means is turned when the automobile is running on a curve or when turning left or right at an intersection. When the driving means operates in conjunction with the steering mechanism of the automobile, each light source module swings around the turning axis via the link mechanism, and the optical axis is directed to the traveling direction of the automobile. Become. Therefore, a so-called AFS function is realized, and a light distribution pattern with higher visibility that irradiates light far along the traveling direction can be obtained.

  When the turning axis of each light source module passes through the vicinity of the center of gravity of the light source module, the moment of inertia at the time of turning around the turning axis of each light source module becomes smaller, and the driving torque of the turning drive means is reduced. It can be smaller and costs can be reduced.

  When the distance from the connection point of each light source module to the link mechanism to the pivot axis is constant, each light source module is swung around the pivot axis via the link mechanism. The turning angle becomes the same, and the same light distribution pattern as a whole is swung left and right.

When the distance from the connection point of each light source module to the link mechanism to the pivot axis is different from each other, the rotation of each light source module is performed when each light source module is swung around the pivot axis via the link mechanism. The angles will be different from each other.
Therefore, the light distribution pattern also changes when swinging. For example, when facing forward, the light is irradiated forward with a relatively narrow irradiation angle, and when swinging left and right, a relatively wide irradiation angle. The light can be irradiated in the traveling direction of the car.

  When the connecting shaft to the link mechanism of the turning drive means is arranged on the same plane as the plane defined by the turning shaft of each light source module, each light source module is connected to the connecting shaft of the turning drive means. The rotation angle is transmitted as it is through the link mechanism, the optical axes of the light source modules are always parallel to each other, and the same light distribution pattern is swung left and right.

  When the connecting shaft to the link mechanism of the turning drive means is arranged at a position shifted from the plane defined by the turning shaft of each light source module, each light source module is connected to the connecting shaft of the turning drive means. The rotation angles are transmitted differently via the link mechanism. Accordingly, the directions of the optical axes of the light source modules are different from each other along with the oscillation, and the light distribution pattern changes smoothly with the oscillation.

  When the link mechanism has a degree of freedom in the radial direction with respect to the turning axis of the light source module at the connection point with each light source module, for example, using a cam mechanism or a slide mechanism By providing the degree of freedom, the swing speed of each light source module by the turning drive means can be changed differently. As a result, it is possible to perform swing control with a higher degree of freedom of each light source module.

  When the swivel driving means includes a plurality of drive shafts with different positions with respect to the link mechanism, each drive shaft is driven to rotate, so that each light source module can be driven in a different manner. Various light distribution patterns can be changed, for example, each light source module is swung by the same angle by one drive shaft and each light source module is swung by a different angle by another drive shaft.

  When the light source is an LED, each light source module can be configured to be particularly small and light, so that the entire vehicular lamp can be configured to be small and the torque of the turning drive means can be further reduced. It is possible to use a low-cost drive source.

  In this way, according to the present invention, the plurality of light source modules are swung in the same direction via the link mechanism by the turning drive means. The light distribution pattern can be changed by swinging the optical axis.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to FIGS. 1 to 10.
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 is particularly limited in the following description. As long as there is no description of the effect, it is not restricted to these aspects.

1 and 2 show a configuration of a first embodiment of a vehicular lamp to which the present invention is applied.
1 and 2, a vehicular lamp 10 is configured as a headlight of an automobile, and includes a plurality of (five in the illustrated example) light source modules 11, 12, 13, 14, 15 and these. A link mechanism 16 connected to each other and a motor 17 serving as a turning drive means are included.

Since the light source modules 11 to 15 have the same configuration, the configuration of the light source module 11 will be described below.
The light source module 11 includes, for example, a plurality of LEDs (not shown), an optical element such as a focusing lens that focuses light from each LED, and a light blocking member that forms a cutoff, and extends along the optical axis direction. The light is converged to irradiate with a predetermined light distribution pattern by cut-off.

Here, each LED is composed of, for example, a blue LED chip and a phosphor layer disposed around the LED so as to emit white light, and the blue light emitted from the blue LED chip is in the phosphor layer. The phosphor is excited to generate yellow light as excitation light, and white light is emitted to the outside by mixing the yellow light and the blue light from the blue LED chip.
Furthermore, the light emission color of each LED is not limited to white, and other light emission colors may be used.

Further, the light source module 11 is supported so as to be swingable around a vertical axis 11a passing through the vicinity of its center of gravity, and is supported so as to be rotatable with a link mechanism 16 described later at a connection point 11b near the rear end. ing.
As shown in FIG. 1, the light source modules 11 to 15 are arranged adjacent to each other in the horizontal direction and arranged at equal intervals.

In the illustrated case, the link mechanism 16 is composed of a single arm and is pivotably attached at connection points 11b, 12b, 13b, 14b, and 15b near the rear ends of the light source modules 11 to 15. As the arm moves in the left-right direction in FIG. 1, each light source module 11 to 15 can swing at the same swing angle. Specifically, the connection pins implanted in parallel with the vertical axes 11a to 15a at the connection points 11b to 15b of the light source modules 11 to 15 are engaged with the engagement holes provided in the arms of the link mechanism 16. By doing so, it is connected so that turning is possible.
The link mechanism 16 connects the light source modules 11 to 15 so that the optical axes of the light source modules 11 to 15 are substantially parallel to each other.

In the illustrated case, the motor 17 is disposed on the side of the light source module 11, and its drive shaft 17 a swings with respect to the connection point 16 a at the left end of the arm of the link mechanism 16 via the drive portion 17 b. It is attached as possible.
Thereby, when the drive shaft 17a is rotationally driven, the drive portion 17b rotates around the drive shaft 17a, and the arm of the link mechanism 16 is swung left and right in FIG. .

In the illustrated case, the distances between the vertical shafts 11a to 15a and the connection points 11b to 15b of the light source modules 11 to 15 are all selected to be the same, and the drive shaft 17a of the motor 17 and the arm left end of the link mechanism 16 are selected. The distance to the connecting point 16a is also selected to be the same distance.
Thus, when the drive shaft 17a of the motor 17 rotates, the drive portion 17b swings, so that each light source module 11 to 15 swings around the vertical shaft 11a to 15a, respectively. It swings in the same direction by the same angle.

  The vehicular lamp 10 according to the embodiment of the present invention is configured as described above. As shown in FIG. 1, when each light source module 11 faces the front (downward in FIG. 1), each light source module When the LEDs 11 to 15 (not shown) are fed to emit light, the light emitted from the light source modules 11 to 15 is emitted while being condensed along the optical axis, and is substantially forward with a predetermined light distribution pattern. Irradiated towards. Thereby, the light distribution patterns by the light source modules 11 to 15 are superimposed on each other, and a light distribution pattern with sufficient brightness is obtained.

Here, as indicated by an arrow A in FIG. 1, when the motor 17 rotates counterclockwise, the drive portion 17 b similarly swings counterclockwise, and each light source module is connected via the link mechanism 16. 11 to 15 also swing counterclockwise around the vertical axes 11a to 15a, respectively.
At this time, the light source modules 11 to 15 are swung by the same angle in the same direction, and the optical axes of the light source modules 11 to 15 are held substantially parallel to each other as shown in FIG. In the state, it is swung to the left (right in the drawing) toward the front. As a result, the light distribution patterns by the light source modules 11 to 15 are swung while being superposed on each other.
Therefore, for example, when the motor 17 rotates in conjunction with the steering angle of the vehicle steering, the optical axes of the light source modules 11 to 15 are swung in the traveling direction of the vehicle. A so-called AFS function can be realized.

In this case, each of the light source modules 11 to 15 is configured to be small, and since the vertical axes 11a to 15a pass through the vicinity of the center of gravity, the light source modules 11 to 15 are arranged around the vertical axes 11a to 15a. The moment of inertia when swinging is very small. That is, the moment of inertia is significantly reduced to about 1/7 as compared with the case of the entire swivel system shown in FIG.
Therefore, even if the motor 17 is relatively small and has a low torque, the light source modules 11 to 15 can be easily and surely swung via the link mechanism 16, and can be small and low cost. A motor 17 can be used.
Further, since each of the light source modules 11 to 15 is small, as shown by a solid line X in FIG. 3, the operation space for swinging is small. For example, the entire swivel system shown in FIG. Compared with the operation space Y in this case, the operation space can be reduced by 1/5 or more.

FIG. 4 shows the configuration of the second embodiment of the vehicular lamp according to the present invention.
4, the vehicular lamp 20 has substantially the same configuration as the vehicular lamp 10 shown in FIG. 1, but the distance between the motor 17 and the connection point 16a of the link mechanism 16 is the same as that of each of the light source modules 11 to 15. The engagement holes that are selected to be shorter than the distance from the vertical shafts 11a to 15a to the connection points 11b to 15b and that form the connection portions of the link mechanism 16 with respect to the light source modules 11 to 15 have different lengths in the longitudinal direction. Are different in that they are formed longer.
More specifically, the engagement hole for the light source module 11 is the longest, the engagement holes for the light source modules 12 to 14 are sequentially shortened, and the engagement hole for the last light source module 15 is the same as that of the vehicle lamp 10 of FIG. It is formed in a circular shape as in the case.

According to the vehicular lamp 20 having such a configuration, when each of the light source modules 11 to 15 faces the front as shown in FIG. 4, the light source modules 11 to 15 act similarly to the vehicular lamp 10 shown in FIG. The light distribution patterns by the light source modules 11 to 15 are superimposed on each other, and a light distribution pattern with sufficient brightness is obtained.
On the other hand, as indicated by an arrow A in FIG. 4, when the motor 17 rotates counterclockwise, the driving portion 17 b similarly swings counterclockwise, and each link mechanism 16 The light source modules 11 to 15 also swing counterclockwise around the vertical axes 11a to 15a, respectively.

At this time, since the distance between the drive shaft 17a of the motor 17 and the connection point 16a to the link mechanism 16 is selected to be short, the left end of the arm of the link mechanism 16 is relatively large in the radial direction, that is, downward in FIG. The connecting points 11b to 15b of the light source modules 11 to 15 are different from each other in the radial direction with respect to the vertical axes 11a to 15a while sliding in the engagement holes of the link mechanism 16, respectively. In other words, the light source module on the left side in FIG. As a result, each of the light source modules 11 to 15 swings in the same direction as each other, but at a different angle from each other, that is, as the light source module on the left in FIG.
Therefore, as shown in FIG. 5, the optical axes of the light source modules 11 to 15 are swung so as to extend over a relatively wide angle range, and the light distribution patterns of the light source modules 11 to 15 are mutually different. A slight light distribution pattern is obtained with a slight shift. Therefore, for example, a light distribution pattern suitable for traveling on a curve with a relatively small radius of curvature or turning right or left at an intersection can be obtained.

FIG. 6 shows the configuration of a third embodiment of the vehicular lamp according to the present invention.
In FIG. 6, the vehicular lamp 30 has substantially the same configuration as that of the vehicular lamp 20 shown in FIG. 4, but differs in that the motor 17 includes a second drive shaft 17c. Yes.
The distance between the second drive shaft 17c and the connection point 16a of the link mechanism 16 is selected to be the same as the distance from the vertical shafts 11a to 15a of the light source modules 11 to 15 to the connection points 11b to 15b. The first drive shaft 17a is operated independently.

According to the vehicular lamp 30 configured as described above, only the second drive shaft 17c rotates, so that each of the light source modules 11 to 15 is similar to the vehicular lamp 10 shown in FIG. As shown in FIG. 7, they swing in the same direction by the same angle.
As a result, as shown in FIG. 9, the entire light distribution pattern L retains the same shape and swings to the left. For example, it is suitable for traveling on a curve having a relatively large radius of curvature such as an expressway. The light distribution pattern L1 has a high luminous intensity far away.

Further, by rotating only the first drive shaft 17a, the light source modules 11 to 15 are arranged in the same direction as shown in FIG. 8, as in the case of the vehicle lamp 20 shown in FIG. However, it will swing by different angles.
As a result, as shown in FIG. 10, the light distribution patterns L are shifted from each other by different angles. For example, when running on a curve having a relatively small radius of curvature or turning left or right at an intersection, the light distribution pattern L should be visually recognized. The light distribution pattern L2 is suitable for visually recognizing objects such as road shoulders and pedestrians.

  Further, the first drive shaft 17a and the second drive shaft 17c are rotated at the same time or shifted in time in conjunction with the steering angle and traveling speed of the steering of the vehicle. By oscillating at different oscillating speeds and oscillating angles, the light distribution pattern changes smoothly even during oscillating, making the light distribution pattern more diverse and easy to see for the driver. Will be obtained.

In the above-described embodiment, the LED is used as a small light source constituting the light source module. However, the present invention is not limited to this, and other types of light emitting elements such as laser elements and other types of small light sources may be used. Good.
In the above-described embodiment, a so-called slide mechanism is introduced by providing an engagement hole extending in the longitudinal direction in the link mechanism 16 in order to obtain a degree of freedom in the radial direction with respect to the oscillation of the light source module. For example, another mechanism such as a cam mechanism may be used.
Furthermore, in the above-described embodiment, the drive shafts 17a and 17c of the motor 17 directly rotate the drive unit 17b, but via a transmission mechanism such as a belt mechanism or a speed reduction mechanism such as a gear mechanism. The drive unit 17b may be rotated, and the drive shaft 17a of the motor 17 is connected to the connection point 16a at the left end of the arm of the link mechanism 16. However, the present invention is not limited thereto, and the light source modules 11 to 15 are not limited thereto. May be connected to any one of the vertical axes 11a to 15a.
In the above-described embodiment, the vehicular lamp 10 as a headlamp to which the present invention is applied is described. However, the present invention is not limited to this, and other examples such as an auxiliary headlamp using a similar small light source. It is obvious that the present invention can be applied to other types of vehicle lamps and other lamps for general lighting.
