    TECHNICAL AREA
    The present description relates to a vehicle lamp used for an automobile or the like.
    BACKGROUND
    As a light source of a conventional vehicle lamp, in particular a headlight, a halogen lamp or a high intensity discharge lamp (HID for "High Intensity Discharge" in English) has been widely used. However, in place of these lamps, a vehicle lamp using a semiconductor light source such as, for example, a light emitting diode (LED) or a laser diode (also called a semiconductor laser) has recently been developed.
    To improve visibility at a remote location, a vehicle lamp with a radiating lamp has been developed in a directed manner to a more remote location (here called "additional high beam") which receives a radiation from a running traffic light. Since the additional high beam light source requires a strong directivity, a laser diode or semiconductor light source of high luminance similar to the laser diode is used. In addition, the high luminance light source such as, for example, a laser diode or an LED, can also be used for a high beam or common crossing. SUMMARY [0005] Since the extra high beam provides a directed light distribution, it is expected to further improve the visibility at a remote location on a winding road by rotating the beam axis to the left and to the right. depending on the importance of the turn. The inventors of the present description have studied the additional road light source having the pivoting function, and accordingly, have been led to recognize the following problems.
    Figure 1 is a view illustrating a vehicle that is driven on a winding road. When a reference vehicle 2 is driven on a winding road 6 illustrated in FIG. 1, the beam axis of the additional high beam is inclined with respect to the direction of the driver's line of sight, that is, say, to the right. The extra high beam may dazzle a previous or oncoming vehicle (collectively referred to as a "forward vehicle"). Thus, when a vehicle ahead is detected, for example, by a camera, the additional high beam is off or attenuated.
    [0007] The winding road 6 is a so-called blind road. The oncoming vehicle 4 is driven in a range 8 that the reference vehicle 2 does not see, and suddenly appears in the radiation range of the additional high beam of the reference vehicle 2, moreover, in a position close to the source of light. Since there is a time difference between the moment when the reference vehicle 2's camera has recognized the oncoming vehicle 4 and the time when the additional high beam is off (attenuated), a powerful glare can be caused to the oncoming vehicle 4 in the case of Figure 1.
    In addition, on a winding road with a small radius of curvature R, for example, a guardrail or a wall located in the direction of the beam axis becomes a radiation target 10. As the radius With the curvature R decreasing, the distance between the reference vehicle 2 and the radiation target 10 decreases. As a result, the driver of the reference vehicle 2 is exposed to glare produced by the beam reflected by the radiation target 10.
    The present disclosure has been made in consideration of this circumstance and an exemplary objective of one aspect of the present disclosure is to provide a vehicle lamp in which the glare of a vehicle ahead or reference can be deleted.
    An aspect of the present disclosure relates to a vehicle lamp. The vehicle lamp includes a lamp unit that generates a beam for radiating directed to a remote location, an ignition / extinguishing circuit that illuminates a light source provided in the lamp unit and a pivoting mechanism that makes rotate the directed beam. The ignition / extinction circuit is configured to decrease the amount of light from the light source as the pivot angle of the directed beam increases.
    According to this aspect, the glare of a vehicle ahead or clean can be mitigated or removed while driving on a winding road.
    The ignition / extinction circuit may be configured to turn off the light source when the pivot angle exceeds a predetermined threshold value.
    The ignition / extinction circuit can be configured to, when a target light quantity is updated according to the variation of the pivot angle, gradually change the amount of light from the light source to reach As a result, the rapid variation of the brightness of the visual field can be attenuated or suppressed, for example, when the steering wheel is turned suddenly, so that the security can be improved.
    [0014] Another aspect of the present disclosure also provides a vehicle lamp. The vehicle lamp includes a lamp unit that generates a directed beam to radiate directed to a remote location, an on / off circuit that illuminates a light source provided in the lamp unit, and a pivot mechanism that rotates the directed beam. The ignition / extinction circuit is configured to decrease the amount of light from the light source as the radius of curvature of a winding road decreases.
    According to this aspect, the glare of a vehicle ahead or clean can be attenuated or removed while driving on a winding road.
    With the vehicle lamp according to the present disclosure, the glare can be attenuated or suppressed.

    Figures 2A and 2B are perspective views of a vehicle lamp 100 according to an exemplary embodiment. Fig. 2A shows the appearance of the vehicle lamp 100. The vehicle lamp 100 comprises a passing beam unit 102, a high beam unit 104, an additional high beam unit 106, a flashing light unit 108, a template light 110 and a lamp body 112 receiving these components, and a cover 114. The arrangement or design of the respective lamp units differs depending on the vehicle model and is not specifically limited.
    The additional high beam unit 106 is a lamp configured to radiate directed towards a location more distant than the one to which the current highway light unit 104 radiates to improve visibility at a remote location. Each of the units includes, for example, a light source, an optical system, and an on / off circuit, and receives power from a vehicle-side battery so that the power on / off of the amount of light is controlled based on a command from an ECU on the vehicle side. In the present exemplary embodiment, the supplemental high beam unit 106 is configured to rotate the beam axis left and right depending on the magnitude of the turn. Thus, it is expected to improve visibility at a remote location on a winding road.
    FIG. 2B is a perspective view illustrating the supplementary high beam unit 106. The additional high beam unit 106 comprises a light source 120, an optical system 122, a pivot mechanism 124 and a ignition / extinction circuit 126. The light source 120 is a semiconductor light source of high luminance and may be for example a combination of a laser diode and a phosphor. Alternatively, the light source 120 may be a white LED or a combination of red, green and blue LEDs. The optical system 122 includes, for example, a lens or reflector and is configured to form an appropriate directed light distribution at a remote location.
    The pivoting mechanism 124 comprises for example an actuating device and its drive circuit. The pivot mechanism 124 rotates the beam axis of the supplemental high beam unit 106 to the left and right based on a command from the vehicle-side ECU. On / off circuit 126 provides a drive current for emitting light from light source 120 with a desired luminance.
    FIG. 3 is a block diagram of a lamp system 300 provided with the vehicle lamp 100 according to the exemplary embodiment. The lamp system 300 includes a battery 302, an electronic control unit (commonly referred to as a vehicle electronics control unit ECU) 304, and a vehicle lamp 100. Although a vehicle is provided with a pair of lamps left and right vehicle 100, Figure 3 illustrates only one side of the vehicle lamps.
    The vehicle ECU 304 is connected to the vehicle lamp 100 via a control line such as, for example, a CAN (Controller Area Network) bus 306 and controls the vehicle lamp 100 integrally. An on / off control SI to turn on / off a lamp and information (driving information) S2 representing the driving state are for example transmitted from the vehicle ECU 304 to the vehicle lamp 100.
    The vehicle lamp 100 comprises a light source 120, a pivoting mechanism 124, an ignition / extinguishing circuit 200 and a lamp ECU 210. FIG. 3 represents only the configuration of the light unit of FIG. additional route 106 of the vehicle lamp 100. As described above, the light source 120 may be a laser diode, but another semiconductor light source having a high directivity may be used.
    The ignition / extinction circuit 200 corresponds to the ignition / extinction circuit 126 of FIG. 2B and supplies a driving current (lamp current) Ild to the light source 120 to cause the emission of light by the light source 120. The ignition / extinction circuit 200 includes a driver 202 and a controller 204. The driver 202 receives a light control signal S3 from the controller 204 and provides at the light source 120 a driving current (lamp current) ILd is a function of the light control signal S3. As a driving circuit 202, a constant current converter is preferably used which not only supplies a supply voltage VDd to the light source 120 by increasing or decreasing the voltage, but also stabilizes the power supply. Ild driving in the light source 120 to a target current function of the light control signal S3. In addition, the topology of the constant current converter is not specifically limited. The driving circuit 202 can perform at the same time an analog light control which controls the value of the current of the driver ILd and a pulse width modulation control (PWM for "Pulse Width Modulation") which switch the ILd driver at high speed so as to change its duty cycle, or can perform only one of the commands. The light control signal S3 may comprise a signal S3a for controlling the analog light control and a signal S3b for controlling the light control by PWM.
    The controller 204 generates the light control signal S3 as a function of a control signal S4 from the lamp ECU 210. The control signal S4 will be described later.
    The lamp ECU 210 comprises a central processing unit (CPU) 212 and a semiconductor switch 214. The CPU 212 generates the control signal S4 to control the light source 120 in function. of the ignition command S1 and the driving information S2 coming from the vehicle ECU 304. The control signal S4 can comprise data S4a which impose the switching on / off of the light source 120 and the information S4b that directly or indirectly impose the amount of light from the light source 120.
    The driving information S2 comprises for example the presence / absence of a vehicle ahead, the vehicle speed and the steering angle. When the switch-on / switch-off command SI requires ignition, and the presence / absence of a vehicle ahead, the vehicle speed and the steering angle meet a predetermined condition, the lamp ECU 210 switches the S4a data to an ignition level. The driving information S2 may furthermore comprise, for example, information (pitch, roll and yaw) coming from an acceleration sensor or a gyroscopic sensor and opening / closing information of a door.
    The semiconductor switch 214 is provided on a power line between the battery 302 and the driver 202 and the switching on / off of the semiconductor switch 214 is controlled according to the control signal S5 from the CPU 212. The semiconductor switch 214 becomes "on" in the on state of the light source 120.
    In addition, the CPU 212 generates a pivot control signal S6 from the driving information S2 to control the pivot angle of the pivot mechanism 124. The CPU 212 detects a winding road based on the information angle of rotation, the car navigation information and camera information included in the driving information S2 or determines the pivot angle Θ based on combinations of the information. The pivot mechanism 124 rotates the light source 120 by a pivot angle Θ imposed by the pivot control signal S6.
    The amount of light from the light source 120 is greatest at the moment of driving on a straight line and accordingly, takes the greatest value when Θ = 0 °. The on / off circuit 200 decreases the amount of light from the light source 120, in other words, decreases the drive current ILd as the pivot angle Θ of the pivot mechanism 124 increases. Figs. 4A-4F are views illustrating the relationship between the pivot angle Θ and the amount of light.
    In Figure 4A, the amount of light decreases linearly with respect to the pivot angle Θ (i). For example, a positive swivel angle correspond corresponds to a rightward swivel and a negative swivel angle correspond corresponds to a left swivel.
    The amount of light can be horizontally symmetrical or asymmetrical with respect to the pivot angle Θ = 0 °.
    Alternatively, the amount of light may decrease in a downward convex curve shape relative to the pivot angle Θ (ii). The convex curve downwards can be for example a function of y = 1 / x or y = éx. Since it is difficult for human beings to be aware of a variation of light when the light is powerful, a variation in natural brightness for a human being can be implemented by increasing the variation of light when the amount of light varies. Light is important and decreasing the variation of light when the amount of light is low.
    In FIG. 4B, when the pivot angle Θ is included in a predetermined range ΔΘ close to 0 °, the light is emitted with the same quantity of light as for the straight line (Θ = 0 °), and when the pivot angle Θ exceeds the range, the amount of light decreases.
    In FIG. 4C, when the pivoting angle Θ exceeds a predetermined range (Θ- to Θ +), the quantity of light becomes zero (0), that is to say that the lamp is extinguished. In Fig. 4D, when the pivot angle θ exceeds a predetermined range (Θ- to Θ +), the amount of light is locked at a predetermined lower limit value.
    It will be understood that FIG. 4E is a combination of FIGS. 4B and 4D. It will be understood that Figure 4F is a combination of Figures 4B and 4C. In addition, the slope portions of Figs. 4B-4F may be replaced by convex downward curves as in (ii) in Fig. 4A.
    The amount of light control based on the pivot angle can be performed in (1) the vehicle lamp 100 or (2) the vehicle ECU 304 as described below. When performed in the vehicle lamp 100, the amount of light control can be performed in (IA) the CPU 212 or (IB) the controller 204. Each of the cases will be described below. (IA) Control by the CPU 212.
    The driving information S2 which comprises at least one of the steering angle, the navigation information, the camera information and the radius of curvature R of a winding road are applied to the input. of the CPU 212 from the vehicle ECU 304. The CPU 212 determines a pivot angle Θ from the driving information S2 and outputs a pivot control signal S6 to the pivot mechanism 124. In addition, in the CPU 212, an arithmetic equation indicating the relationship between the pivot angle Θ and the amount of light is defined. From the arithmetic equation, the CPU 212 determines the amount of light and generates light quantity information S4b to impose the amount of light. The on / off circuit 200 turns on the light source 120 according to the light quantity information S4b.
    Alternatively, in the CPU 212, a table indicating the relationship between the pivot angle Θ and the amount of light can be prepared to determine the amount of light with reference to the table. Since the amount of light control in the CPU 212 can use the arithmetic equation or the table, the relationship between the pivot angle and the amount of light can be flexibly defined.
    Otherwise, the pivot angle Θ can be determined by the vehicle ECU 304. In this case, the control signal S4 can include data indicating the pivot angle Θ and the CPU 212 can determine the amount of light from the data. (IB) Control by the controller 204.
    As described above, the pivot angle Θ is determined by the CPU 212 or the vehicle ECU 304. The CPU 212 outputs to the ignition / extinction circuit 200 information indicating the angle of rotation. pivoting Θ (pivot angle information S4b). The pivot angle information S4b may be digital data or an analog signal.
    The controller 204 determines the amount of light from the pivot angle information S4b. To obtain the determined amount of light, the controller 204 controls the drive current ILd through any of the PWM light control and the analog light control, or a combination of them.
    When the controller 204 includes, for example, a CPU or a digital arithmetic processing circuit, the amount of light can be determined in the same manner as that used in the CPU 212 of (IA).
    The control device 204 can also be realized by means of an analog circuit. Figs. 5A to 5F are circuit diagrams illustrating an exemplary configuration of the controller 204. These circuit diagrams illustrate only the configuration corresponding to the range Θ> 0 °. An analog voltage VS4b can be a signal indicating the absolute value of the pivot angle.
    The analog voltage VS4b indicating the pivot angle information is applied to the input of the controller 204a of Figure 5A. The control device 204a comprises an inverting amplifier 220 which amplifies by inverting the analog voltage VS4b and generates a light control signal VS3 of the analog voltage. The controller 204a of Figure 5A may implement the control feature of Figure 4A.
    The control device 204b of FIG. 5B comprises a blocking circuit 222, in addition to the inverting amplifier 220. The blocking circuit 222 blocks the light control signal VS3 so as not to exceed a predetermined voltage VREf · The predetermined voltage VREf defines a normal lamp current on the straight line (pivot angle Θ = 0). The controller 204b of Figure 5A may implement the control feature of Figure 4B.
    The control device 204c of FIG. 5C comprises a comparator 224, in addition to the inverting amplifier 220. The comparator 224 compares the analog voltage VS4b to a predetermined threshold voltage Vth and pulls the output of the analog voltage Vs4b when VS4b <VTh · The comparator 224 may for example include an output stage of the open collector type (open drain). The controller 204c of FIG. 5C can implement the control characteristic of FIG. 4C and the threshold voltage Vth corresponds to Θ +.
    The control device 204d of FIG. 5D comprises a blocking circuit 226, in addition to the inverting amplifier 220. The blocking circuit 226 blocks the light control signal VS3 so as not to be less than one. predetermined voltage VMin- The control device 204d of FIG. 5D can implement the control characteristic of FIG. 4D.
    The control device 204e of FIG. 5E comprises the blocking circuit 222 and the blocking circuit 226, in addition to the inverting amplifier 220. The blocking circuit 222 blocks the light control signal VS3 so as to do not exceed the predetermined voltage VREf. The blocking circuit 226 blocks the light control signal VS3 so as not to be less than the predetermined voltage VMiN. The control device 204e of FIG. 5E can implement the control characteristic of FIG. 4E.
    The control device 204f of FIG. 5F comprises the blocking circuit 222 and the comparator 224, in addition to the inverting amplifier 220. The control device 204f of FIG. 5F can implement the control characteristic of FIG. Figure 4F.
    When the steering wheel is rotated so that the pivot angle Θ varies rapidly, the amount of light fluctuates rapidly. Otherwise, in the case of executing the command of Fig. 4C or 4F, when a pivoting operation beyond Θ + (or Θ-) occurs, the amount of light fluctuates rapidly. As a result, the brightness of the visual field varies rapidly, thereby causing an uncomfortable feeling in a driver. Thus, when the light quantity information S4b is updated as a function of the pivoting operation, the ignition / extinction circuit 200 progressively modifies the light quantity of the light source 120 to reach the target amount of light. update. When a progressive transition time of, for example, 0.1 to 10 s, preferably 0.2 to 5 s, is provided, it is possible to ensure that the variation in the amount of natural light is such that the necessary field of view can be guaranteed by reducing the uncomfortable feeling that can be communicated to a driver. The dimming control can be implemented by adding to the controller 204 a dimming circuit slowing down the analog voltage VS3 (light control signal S3). The progressive variation circuit may consist of a CR integrator (low pass filter). When the amount of light is controlled by the CPU 212, the dimming control can be implemented using a counter or a digital filter provided in the CPU 212. In addition, when a forward vehicle is detected, it is necessary to extinguish the lamp immediately and without delay to prevent glare to the vehicle ahead.
    The configuration of the vehicle lamp 100 has been described. The operation of the vehicle lamp 100 will then be described. Figs. 6A-6C are views schematically illustrating the relationship between the amount of light and the radius of curvature. Figure 6A illustrates the driving on a straight line and Figures 6B and 6C illustrate the driving on a winding road. The importance of the amount of light is represented by the importance of hatching. When a vehicle is driven in a straight line as in Figure 6A, the pivot angle Θ is 0 °, and the location in front of the vehicle receives radiation of maximum luminance. When a vehicle is driven on a winding road as in Figure 6B, the pivot angle Θ increases and the amount of light decreases. When the radius of curvature R is further reduced as in Fig. 6C, the pivot angle θ increases further and the amount of light decreases further.
    By comparing FIGS. 6A to 6C in FIG. 6A, the oncoming vehicle 4 may be detected at the furthest location. FIGS. 6B and 6C show blind curves, on which as the radius of curvature R decreases, detection of the oncoming vehicle 4 is difficult and the distance between the reference vehicle 2 and the oncoming vehicle 4 at the time of detection is weak. In the vehicle lamp 100 according to the present exemplary embodiment, the amount of light from the light source 120 at the moment of detection of the oncoming vehicle 4 decreases as the pivot angle Θ increases, in other words, as the radius of curvature R decreases. It is thus possible to attenuate or suppress the glare of the oncoming vehicle 4 during the time from detection of the oncoming vehicle 4 until the light is extinguished or attenuated.
    In addition, as illustrated in FIGS. 6A to 6C, while the distance between the reference vehicle 2 and the radiation target 10 decreases as the radius of curvature R is reduced, the amount of light from the source of light 120 decreases as the radius of curvature R decreases. As a result, it is possible to attenuate or suppress the glare produced by the reflected light from the radiation target 10 to the driver of the reference vehicle 2.
    This description has been made based on an exemplary embodiment using specific terminology, but the exemplary embodiment merely represents the principle and application of this disclosure. Various modifications or alternative arrangements may be made in the exemplary embodiment without departing from the technical idea of the present disclosure. (First modification) [0065] In the exemplary embodiment, the amount of light is controlled based on the pivot angle Θ, but the present disclosure is not limited thereto. For example, the on / off circuit 200 can control the amount of light from the light source 120 as a function of the radius of curvature R of a winding road. Specifically, the on / off circuit 200 can decrease the amount of light from the light source 120 as the radius of curvature R decreases. For example, when a control for shifting the vehicle speed to the swivel angle Θ is performed, the swivel angle Θ can be reduced even while driving on a winding road with a small radius of curvature R. Even in in this case, when the amount of light from the light source 100 is controlled based on the radius of curvature R, the amount of light can be appropriately modified. (Second Modification) In the exemplary embodiment, the lamp of which the light source 120 is rotated by means of the pivoting mechanism has been described, but the present disclosure is not limited thereto. For example, in a lamp that generates a directed beam by reflecting light such as, for example, an LED or DL, against a reflecting mirror, the reflecting mirror can be rotated by means of the pivoting mechanism. In addition, the technical idea of the present disclosure can also be applied to a lamp in which a directed beam is not rotated, and the beam axis is fixed. (Third modification) In the exemplary embodiment, the light source 120 is used for the additional light beam, but the present disclosure is not limited thereto. The light source 120 may also be used for a common road light source which radiates over a high beam area. In addition, the light source 120 may also be used for a light source that radiates on at least a portion of a high beam area.
    It will be understood from the foregoing that various embodiments of the present disclosure have been described herein for explanatory purposes and that various modifications can be made without departing from the scope and spirit of the present invention. present disclosure. Consequently, the various embodiments described here are not intended to be limiting.
