According to the apparatus proposed in Patent Document 1, since a plurality of lamps are collectively arranged, it is advantageous in that it can be completed at one time: an operation of assembling a headlight device assembled in another step to a vehicle body.

The headlight described in Patent Document 1 is a headlight that can be used as one lamp, and can be regarded as having two lamps by utilizing the design effect. That is to say, there is no reduction effect of the number of light sources for the headlight of one lamp mode. On the other hand, a position lamp having a function as a vehicle width lamp requires two lamps to be disposed at least in the left and right directions of the vehicle width. The arrangement of such a position lamp is also shown in Patent Document 1. That is, in conventional devices, the position light bulb still requires two, and is required to reduce the number of position light bulbs. Conventional position lights are only illuminated by the position light bulb and the mirror portion in the vicinity thereof, and require a much larger illumination range with a simple construction.

Therefore, it is desirable to improve the visibility of the position lamp and to reduce the cost by making the light source which essentially requires a plurality of position lamps.

It is an object of the present invention to provide a position lamp and a lighting device including the position lamp for the above problems, which can improve the visibility and reduce the number of light sources.

The present invention for achieving the above object is a position lamp of a locomotive, characterized in that it is provided with a position light bulb disposed at a center portion of the vehicle width direction on a front outer casing provided at a front portion of the vehicle body, a light source casing that is attached to the front casing, covers the position light bulb from the front of the vehicle body, an elongated light guiding portion that guides light emitted from the position light bulb toward both sides in the vehicle width direction, and along the light guide A lens disposed at a front surface of the light guiding portion.

According to a second aspect of the invention, the light guiding unit extends in a rising direction from a central portion corresponding to a position at which the position light bulb is disposed in a vehicle width direction.

According to a third aspect of the invention, the light guiding portion is configured by a cavity surrounded by the lens and the mirror, and the mirror covers the lens from a rear side and has a light passing through the position lamp bulb. A reflecting surface that the light guiding portion reflects toward the vehicle width direction.

According to a fourth aspect of the present invention, a position lamp including the first to third features described above is provided, and a headlight that is separated from the position lamp is provided above the position lamp.

According to a fifth aspect of the present invention, the headlight is disposed on a handlebar outer casing, and the handlebar outer casing is located above the front outer casing.

According to a sixth aspect of the invention, in the position lamp, the end portion in the vehicle width direction extends to be closer to the outer side in the vehicle width direction than the lead line passing through the end portion of the headlight in the vehicle width direction.

According to the invention having the first to sixth features, in the front portion of the vehicle body, light from the position light bulb disposed at the center portion in the vehicle width direction passes through the light guiding portion toward both sides in the vehicle width direction (that is, left and right) The direction reflection is performed by the lens disposed along the light guiding portion toward the front, so that the long irradiation surface that extends left and right in the vehicle width direction is obtained, and the visibility from the front can be improved. The position lamp itself is covered with a light edge casing so as not to be seen from the outside. Therefore, the light source casing is disposed at the center and is identified as having a light source in the vehicle width direction. That is to say, it is possible to make the light source of the position lamp single, and it is easy to reduce the cost.

In particular, by the present invention having the second feature, it is possible to arrange a light guiding portion having a long dimension with respect to the front outer casing in the vehicle width direction. Therefore, a wider irradiation area can be ensured than in the case where the light guiding portion is horizontally arranged. By virtue of the special V-shaped configuration in which the light guiding portion is obliquely extended, good visibility can be expected.

According to the present invention having the fourth feature, by disposing the position lamp from the headlight, it is easily recognized as a lighting device that completely separates the position lamp from the headlight.

According to the present invention having the sixth feature, by making the position lamp extend toward the outside of the headlight, the visibility of the position lamp can be further improved.

Convex V-shaped.

The configuration of the position lamp 18 will be explained. Fig. 4 is a plan view showing a structure of a position lamp, Fig. 5 is a front view, Fig. 6 is a perspective view, and Fig. 7 is a perspective view of a position lamp (i.e., a mirror side) in a state where the lens is removed. As understood from these drawings, the position lamp 18 is composed of a light source 37, a mirror 39, and a lens 40. The light source 37 is, for example, a 10 watt white heat bulb. The reflecting mirror 39 is made of a resin material, and has a reflecting surface on which aluminum is vapor-deposited on the inner surface, and is composed of a cylindrical bulb accommodating portion 41 provided at the center and left and right in the vehicle width direction from the bulb accommodating portion 41. The extended mirror extension 42 is formed. A bulb socket 50 that supports the light source 37 to the mirror 39 is attached to the bottom portion (the wall portion near the rear of the vehicle) 411 of the bulb housing portion 41.

The lens 40 is formed of a transparent resin and has an outer shape corresponding to the front surface of the bulb accommodating portion 41 of the mirror 39. The lens 40 is provided with a central portion 401 that is opaque and prevents the light source 37 from being transmitted from the front (refer to the fourth And extending from the central portion 401 in the same direction as the mirror extension portion 42 and covering the front surface of the mirror extension portion 42 for reflecting light forward from the mirror extension portion 42 (refer to FIG. 4, Fig. 5 is a lens extension portion 43 as a transparent portion penetrated by the line shown in Fig. 45. Similarly, the central portion of the lens 40 may be a transparent portion similarly to the lens extension portion 43. In this case, the back surface of the light source housing 38 is made non-transparent by aluminum vapor deposition or the like so that the light source 37 cannot be worn from the front. through.

As is apparent from the shapes of the lenses 40 shown in FIGS. 4 to 6 , the lens extension portion 43 has an upper wall 431 , a front wall 432 and a lower wall 433 , and an open portion at the rear. On the other hand, as understood from the shapes of the mirrors shown in FIGS. 4 to 7, the mirror extension portion 42 has an upper wall 421, a rear wall 422, and a lower wall 423 and an open portion in the front.

The open portion of the mirror extension portion 42 and the open portion of the lens extension portion 43 form a cavity portion with respect to each other. The hollow portion is configured to be emitted from the light source 37, and as shown by an arrow 45 in Fig. 5, the light reflected by the wall surface of the bulb accommodating portion 41 of the mirror 39 is guided to the left and right in the vehicle width direction. The cross-sectional shape of the cavity portion (light guiding portion) will be described later with reference to Fig. 8.

As shown in Fig. 4, in order to reflect the light emitted from the light source 37 to the inner surface of the mirror extension portion 42, a reflection surface 424 having a stepped shape is formed. The light 45 emitted from the light source 37 is reflected rearward and laterally by the opaque central portion 401, and is reflected from the center portion of the position lamp 18 to the front side while reflecting the reflection surface 424 of the rear wall 422. The range of the outer side (that is, the left and right) end of the vehicle width direction.

The inner surface of the front wall 432 of the lens extension portion 43 may be patterned or knurled to form a concavo-convex shape (indicated by a plurality of dotted lines in the longitudinal direction in FIG. 5). The appearance of the light seen through the lens 40 is changed by the pitch of the uneven shape formed by the patterning or knurling. The structure in which the lens 40 is attached to the mirror 39 can adopt a conventional configuration. For example, as shown in FIGS. 4 and 5, a protruding portion 44 for fixing a bolt is provided at both ends of the lens 40, and can be adopted to pass the The bolt of the protruding portion 44 is fixed to the configuration of the mirror 39.
