  As shown in FIGS. 1 and 2, the lighting device of the present invention is a vehicle equipped with a general steering wheel interlocking system 7 so that it is easy to see by illuminating the front, and informs oncoming vehicles and pedestrians of the presence of the vehicle. It is attached to both sides or one side of the frontal region (not shown), and a direction changing device 2, a light emitting device 3, a detection device 4, and a control device 5 are provided on a case-like base 1. It becomes. The steering wheel interlocking system 7 controls the traveling direction of the vehicle in a freely rotatable manner. The steering wheel interlocking system 7 is generally coaxial with the steering wheel 71, a driving gear 72 fixed to the steering wheel 71, and a variable resistor (VR) 74. When the rotation angle of the handle tube 71 is increased, the current value of the variable resistor 74 is increased, and a larger voltage can be output.

  The base 1 has a housing 11 that defines a space in which the direction changing device 2 and the detection device 4 are built. As the base 1, for example, if it is a Ford Asdan type passenger car, it can be attached to the lower side of the bumper, and if it is an RV type passenger car, for example, it can be attached to the front edge of the roof.

  The direction changing device 2 is provided in the base 1, and a left and right swingable drive shaft 21 that penetrates the housing 11 and is connected to the light emitting device 3, a power unit 22 that moves the drive shaft 21, and a reduction gear device. 23.

  The light-emitting device 3 is connected to the drive shaft 21 and attached to the upper side of the base 1, and in conjunction with the drive shaft 21, a return position in which the irradiation direction is directed in the direction perpendicular to the vehicle, a return position, Between the left and right extreme positions that form a predetermined angle.

  As shown in FIGS. 3 to 5, the detection device 4 is provided in the base 1 and is provided beside the disk-like protruding member 41 and the protruding member 41 connected to the drive shaft 21 of the direction changing device 2. Sensing member 42 and two stop members 43, 43. As for the protrusion member 41, the tongue-like arm 41b protrudes from the annular peripheral part 41a. The sensing member 42 has a notch 42a having a U-shaped cross section with an arm 41b protruding between the ends of the sensing member 42, and the sensor 42b is attached to the inner surface of the notch 42a facing the arm 41b. The detection device 4 is further provided with a stop member 43 and a speed detector 44. The stop member 43 is provided at a position corresponding to two direction limits respectively attached to both sides of the drive shaft 21 so as to form an angle larger than 90 degrees perpendicular to the return position. In this example, the stop member 43 is a fine movement switch, and generates a limit feedback signal when touched. The speed detector 44 measures the traveling speed of the vehicle and generates a speed feedback signal. In this example, the sensing member 42 is a light detector, and the protruding member 41 is a light shielding plate. When the light is blocked by the protruding member 41, an origin feedback signal that returns to the return position is generated.

  The control device 5 is configured to be driven by a power source from the vehicle or a battery, and is electrically connected to the direction change device 2, the detection device 4, and the variable resistor 73 of the steering wheel interlocking system 7, and the light emitting device 3. The main controller 51, the angle signal generator 52, the turning state controller 53, and the control panel 54 are configured so that the return position of the light emitting device 3 is detected and returned when the power source is closed or opened. .

  The main controller 51 receives the origin feedback signal from the sensing member 42, the limit feedback signal from the stop member 43, and the speed feedback signal from the speed detector 44, and controls the direction changing device 2 to rotate the drive shaft 21 left and right. It is set as the structure made to do.

  The angle signal generator 52 is configured to generate an angle feedback signal based on the voltage value of the variable resistor 73 of the handle interlocking system 7 and transmit it to the main controller 51.

  The control panel 54 is provided with an on key 541 and an off key 542 for controlling opening and closing of the light emitting device 3 and a mode key 543 for switching and stopping the automatic control mode.

  Next, the operation of the lighting device according to the present invention will be described with the above configuration with reference to the drawings.

  When the automatic control mode is set by the mode key 543 and the light-emitting device 3 is turned on by the ON key 541, the main controller 51 controls the power unit 22 of the direction changing device 2 and passes through the reduction gear device 23. The light emitting device 3 is turned to the return position via the drive shaft 21 by the drive gear 222 and the driven gear 223.

  When the drive shaft 21 is rotated, the projecting member 41 is swung, and when the arm 41b is brought into contact with any one of the stop members 43 and 43, the main controller 51 rotates the drive shaft 21 in the reverse direction to thereby project the projecting member. The arm 41b again enters the notch 42a of the sensing member 42, enters between the two sensors 42b, blocks the light, and generates an origin feedback signal for returning the light emitting device 3 rotated together with the drive shaft 21 to the return position. Send to controller 51.

  The angle signal generator 52 of the control device 5 generates an angle feedback signal based on the voltage change from the variable resistor 73 due to the rotation angle corresponding to the curve via the handle interlocking system 7 and sends it to the main controller 51. The main controller 51 rotates the light emitting device 3 synchronously with the steering wheel interlocking system 7 of the vehicle via the direction changing device 2. Thereby, the illuminating device can irradiate light while being along the traveling direction of the vehicle, and can illuminate the corner, in particular, and can improve traveling safety.

  Further, the automatic control mode is set by the mode key 543, and when the power source of the light emitting device 3 is closed by the off key 542, the light emitting device 3 is returned to the return position via the drive shaft 21 by the control of the main controller 51. When the light emitting device 3 returns to the return position, all operations are stopped.

  Further, when the setting of the automatic control mode is canceled by the mode key 543 and the light emitting device 3 is turned on by the ON key 541, the light emitting device 3 is not irradiated with the light beam and is held at the return position as it is.

  Further, when the setting of the automatic control mode is canceled by the mode key 543 and the power source of the light emitting device 3 is closed by the off key 542, the light emitting device 3 is not operated and is held at the return position.

  For example, when the running vehicle temporarily stops while the engine is running, the speed detector 44 generates a speed feedback signal according to the running speed that is 0 and sends it to the main controller 51, and the main controller 51 Returns the light emitting device 3 to the return position via the direction changing device 2 and stops the rotation. Thereby, the light-emitting device 3 does not project light unnecessarily, and the oncoming vehicle and the vehicle ahead are not considered. When the vehicle starts running again from the stop, the main controller 51 causes the light emitting device 3 to have the same angle as the handle interlocking system 7 and rotates synchronously with the handle interlocking system 7.

  Further, when a foreign matter enters the direction changing device 2 or the light emitting device 3 hits something and is not the same as the angle of the handle interlocking system 7, the foreign matter is removed and the light emitting device 3 is turned off. Thus, after the light emitting device 3 is returned to the return position, if the power source of the light emitting device 3 is turned on again, the light emitting device 3 can be swung left and right at the same angle in synchronization with the handle interlocking system 7. Thereby, the effort which removes and attaches the light-emitting device 3 can be eliminated.

  The stop member 43 plays a role of contributing to returning the light emitting device 3 to the return position, and also prevents the drive shaft 21 from rotating too much and causing the wiring to become entangled. The rotation angle can also be limited.

  According to the illuminating device of the present invention, the light emitting device is swung in conjunction with the vehicle steering wheel interlocking system via the drive shaft, especially when approaching a Z-shaped, S-shaped or 90 degree curve, etc. Visibility and safety can be further improved by controlling the direction to synchronize with the traveling direction of the vehicle and turn to the same angle.
