JP 2012-84270 A

  However, in the case of a vehicle such as a commercial vehicle having a cab provided above the power source, the occupant can directly view a range closer to the cab (vehicle body) than a general vehicle having a bonnet. Therefore, at the time of low beam, it is necessary to irradiate the range with the lighting device from the viewpoint of the occupant viewing such a range. In particular, when a projector-type lamp is used for a low beam, it is difficult to irradiate a range close to the cab, and thus a measure for irradiating the range is necessary.

  The objective of this indication is providing the illuminating device and vehicle which a passenger | crew can visually recognize the range close | similar to the vehicle body at the time of a low beam.

The lighting device according to the present disclosure is:
A lighting device that is provided on the vehicle body and can change a light distribution pattern between a high beam and a low beam,
A first illumination unit and a second illumination unit that illuminate the front of the vehicle body during the low beam;
The second illumination unit irradiates a range closer to the vehicle body than an irradiation range of the first illumination unit.

The vehicle according to the present disclosure is
A cab-over body,
The above-described illumination device, wherein the first illumination unit and the second illumination unit are provided in a front portion of the vehicle body,
Prepare.

  According to the present disclosure, an occupant can visually recognize a range close to the vehicle body during low beam.

1 is a perspective view of a vehicle according to an embodiment of the present disclosure. It is the figure which looked at the mode of irradiation by the illuminating device at the time of a low beam from the side part side of a vehicle. It is the figure which looked at the mode of irradiation by the illuminating device at the time of a low beam from the upper side of vehicles.

  Hereinafter, embodiments of the present disclosure will be described in detail based on the drawings. FIG. 1 is a perspective view of a vehicle 1 according to an embodiment of the present disclosure.

  As shown in FIG. 1, the vehicle 1 is a large vehicle such as a so-called cab-over type commercial vehicle, and has a cab 2 (vehicle body) provided above a power source. On the front surface of the cab 2, an illumination device 10 including a first illumination unit 11 and a second illumination unit 12 is provided.

  The illuminating device 10 is a headlamp configured to be able to change a light distribution pattern into a high beam and a low beam whose irradiation range is closer to the cab 2 than the high beam. The illumination device 10 according to the present embodiment irradiates the front of the cab 2 only with the first illumination unit 11 when the beam is high, and forwards the cab 2 with both the first illumination unit 11 and the second illumination unit 12 when the beam is low. Irradiate. In addition, during the high beam, a high beam dedicated illumination unit may be provided separately from the first illumination unit 11 and the second illumination unit 12.

  The first illuminating unit 11 and the second illuminating unit 12 are respectively provided at the front portions on the left and right sides of the cab 2.

  The first illumination unit 11 is, for example, a projector-type illumination unit, and illuminates the front of the cab 2 in both high beam and low beam modes as described above.

  The second illuminating unit 12 is, for example, a parabolic illuminating unit, and as described above, the second illuminating unit 12 is turned off at the time of the high beam and is turned on at the time of the low beam to irradiate the front of the cab 2. The installation size of the second illumination unit 12 on the cab 2 is smaller than the installation size of the first illumination unit 11 on the cab 2. The installation position of the second illumination unit 12 on the cab 2 is outside the installation position of the first illumination unit 11 on the cab 2.

  As shown in FIG. 2, the second illumination unit 12 irradiates a range on the cab 2 side with respect to the irradiation range 11 </ b> A of the first illumination unit 11. Specifically, the irradiation range 12A of the second illumination unit 12 is a range in which the occupant 3 can directly view from the cab 2, and is closer to the cab 2 than the irradiation range 11A of the first illumination unit 11 in the front-rear direction of the vehicle 1. Includes the entire range. An arrow 3 </ b> A in FIG. 2 indicates a line of sight when the occupant 3 sees a position P closest to the cab 2 within a range in which the occupant 3 can directly view the cab 2.

  The irradiation range 11A of the first illumination unit 11 is a range of the road surface 4 sandwiched between the broken line 11B and the broken line 11C. The irradiation range 12A of the second illumination unit 12 is a range of the road surface 4 sandwiched between the broken line 12B and the broken line 12C.

  Here, for example, when the front of the cab 2 is irradiated only by the first illumination unit 11 at the time of the low beam, the range on the cab 2 side from the broken line 11C in the irradiation range 11A is not irradiated. In this case, when the occupant 3 looks directly at the position P, the position P deviates from the irradiation range 11A, and thus the occupant 3 cannot visually recognize the position P.

  In particular, in the case of the cab-over type vehicle 1, since the bonnet is not provided, the occupant 3 can directly view a range close to the cab 2. Therefore, in such a vehicle 1, at the time of a low beam, the passenger | crew 3 needs to irradiate the said range with the illuminating device 10 from a viewpoint of visually recognizing the said range.

  Therefore, in the present embodiment, the position P is included in the irradiation range 12A of the second illumination unit 12. That is, since the area close to the cab 2 can be irradiated during low beam, the occupant 3 can surely see the position P.

  Moreover, since the 2nd illumination part 12 irradiates the full range which can see the passenger | crew 3 directly on the cab 2 side from the irradiation range 11A of the 1st illumination part 11 in the front-back direction, the area | region where the passenger | crew 3 approached the cab 2 Can be reliably recognized.

  As shown in FIG. 3, the irradiation range 12 </ b> A of the second illumination unit 12 is wider than the irradiation range 11 </ b> A of the first illumination unit 11 in the width direction of the cab 2 (left-right direction in FIG. 3). Thereby, since the range in which the cab 2 is closer is widely irradiated, the range in which the occupant 3 is close to the cab 2 can be easily seen.

  Moreover, since the 2nd illumination part 12 is smaller than the 1st illumination part 11, when arrange | positioning two illumination parts in the cab 2, it is easy to arrange | position the 2nd illumination part 12 in the space where the cab 2 was vacant. it can. Moreover, since the 2nd illumination part 12 is smaller than the 1st illumination part 11, the light quantity itself of the 2nd illumination part 12 becomes smaller than the light quantity of the 1st illumination part 11, Therefore The consumption by using two illumination parts Electric power can be minimized.

  In addition, since the second illumination unit 12 is located outside the first illumination unit 11, a wider range can be irradiated in the width direction of the cab 2.

  Moreover, since the 2nd illumination part 12 is used at the time of a low beam, it should just irradiate only the range of the cab 2 side rather than the irradiation range 11A of the 1st illumination part 11, ie, the range close | similar to the cab 2. FIG. Therefore, since the light quantity of the 2nd illumination part 12 can be made small compared with the light quantity of the 1st illumination part 11, the power consumption by using two illumination parts can be suppressed to the minimum.

  Moreover, since the 1st illumination part 11 is a projector-type illumination part, although it is difficult to irradiate the range close to the cab 2, by using the parabolic 2nd illumination part 12, the said range can be irradiated reliably. Can do.

  In the embodiment described above, the irradiation range 11A of the first illumination unit 11 and the irradiation range 12A of the second illumination unit 12 overlap each other, but the present disclosure is not limited to this and overlaps each other. It is not necessary.

  Moreover, in the said embodiment, although the 2nd illumination part 12 was a structure smaller than the 1st illumination part 11, this indication is not limited to this, As long as there is no problem in arrangement space, the 1st illumination part 11 is sufficient. The configuration may not be smaller than that.

  Moreover, in the said embodiment, although the 2nd illumination part 12 was located in the outer side of the cab 2 rather than the 1st illumination part 11, this indication is not limited to this, As long as there is no problem in arrangement space, It may be a position.

  In addition, each of the above-described embodiments is merely an example of implementation in carrying out the present disclosure, and the technical scope of the present disclosure should not be construed in a limited manner. That is, the present disclosure can be implemented in various forms without departing from the gist or the main features thereof.

  The illuminating device of the present disclosure is useful as an illuminating device and a vehicle that allow an occupant to visually recognize a range close to the vehicle body during low beam.
