Description

  The present invention relates to a headlight mounted on a motorcycle.

  A vehicle represented by a motorcycle is generally equipped with a headlight including a light source for a low beam and a light source for a high beam. Various structures of such headlights are known (see, for example, Patent Document 1 (FIG. 8)).

  As shown in FIG. 8 of Patent Document 1, the headlight (10) (the numbers in parentheses indicate the symbols described in Patent Document 1. The same shall apply hereinafter) has an upper light emitting section for low beam ( 110L), a lower light emitting part (112L) for high beam is arranged below the upper light emitting part (110L), and a position lamp (130) is arranged below the lower light emitting part (112L). Yes. In the upper light emitting section (110L), the light emitted from the low beam light source (114) is reflected by the upper reflector (116). In the lower light emitting section (112L), the light emitted from the high beam light source (118) is reflected by the lower reflector (120).

  Further, the upper light emitting part (110L) and the lower light emitting part (112L) are divided by a front extension part (117b) provided at the lower part of the upper reflector (116) and an extension member (126L). For this reason, at the time of low beam lighting, the light emitted from the low beam light source (114) brightens only the upper light emitting section (110L). Since the light from the low beam light source (114) is not irradiated on the lower light emitting section (112L), the lower light emitting section (112L) is not brightened.

  The lower light emitting part (112L) and the position lamp (130) are divided by a front extension part (121b) provided at the lower part of the lower reflector (120) and an extension cover (104). For this reason, when the high beam is lit, the light emitted from the high beam light source (118) brightens only the lower light emitting section (112L). On the other hand, the upper light emitting unit (110L) does not become bright.

  That is, when the light emitting units (110L and 112L) are provided above and below and only one of them emits light, the other light emitting unit (110L or 112L) does not emit light, and the area of the light emitting unit is small.

  In recent years, at the time of high beam lighting, in addition to the high beam light source (118), the low beam light source (114) has been irradiated. In this case, when the high beam is turned on, the upper and lower light emitting portions (110L, 112L) become brighter, and the area of the light emitting portion increases.

  On the other hand, at the time of low beam lighting, as described above, only the upper light emitting unit (110L) is bright and the lower light emitting unit (112L) remains dark, so the area of the light emitting unit remains small. However, from the viewpoint of appearance by light, there is a demand for a technique that can increase the area of the light emitting section even during low beam lighting.

JP 2014-184785 A

  It is an object of the present invention to provide a headlight in which the area of the light emitting portion of the headlight can be increased even when the low beam is turned on in a headlight in which a low beam region and a high beam region are separated by a partition wall. .

The second reflecting surface includes a front reflecting surface that reflects light from the high-beam LED light source forward, and a third reflecting surface that is disposed on an extension portion that extends forward from an end of the front reflecting surface. The light guide space guides a part of light emitted from the low beam side LED light source to the third reflecting surface .

In the invention according to claim 2 , the partition wall is disposed so as to overlap the extension part in a plan view, and a fourth reflection surface for irradiating light from the third reflection surface forward is provided on the lower surface of the partition wall. It is characterized by being.

The invention according to claim 3 is characterized in that the third reflecting surface and the fourth reflecting surface are constituted by a diffuse reflecting surface for diffusing light.

In the invention which concerns on Claim 4 , a 1st reflective surface and a partition are comprised separately, and the light guide space is comprised by the front-end edge of a 1st reflective surface, and the rear-end edge of a partition, 1st reflective surface The front end edge is provided below the rear end edge of the partition wall.

In the invention according to claim 5 , the first substrate on which the low beam side LED light source is mounted is provided on the upper part of the reflector, and at least part of the first substrate is disposed between the first reflecting surface and the second reflecting surface, and the high beam side is provided. A second substrate for mounting the LED light source is provided, and at least one of the first substrate and the second substrate is formed with an engagement hole penetrating in the vertical direction, and the engagement member is inserted into the engagement hole in the vertical direction. Thus, at least one of the first substrate and the second substrate is engaged with the reflector.

In the invention according to claim 6 , below the low beam side LED light source provided on the first substrate, the reflector guides light from the low beam side LED light source to the first reflecting surface and the light guide space. A hole for light is provided, and the hole has a hole shape along the first reflecting surface and the light guide space .

  In the invention which concerns on Claim 1, a reflector is provided with a 1st reflective surface in the site | part above a partition, and a 2nd reflective surface is provided in the site | part below a partition. The low beam side LED light source is disposed at a position to irradiate one of the first reflecting surface and the second reflecting surface, and the high beam side LED light source is disposed at a position to irradiate the other of the first reflecting surface and the second reflecting surface. The When only the low beam side LED light source is turned on, the high beam side LED light source is not turned on, and thus the other light emitting region in the housing is not turned on.

  However, since the partition wall is provided with a light guide space for guiding at least part of the light emitted from the low beam side LED light source to the high beam side reflection surface, the light from the low beam side LED light source is transmitted from the light guide space to the other light emitting region. And the other light emitting region can be turned on. As a result, the entire headlight divided by the partition walls can be illuminated. That is, in the headlight in which the low beam region and the high beam region are divided by the partition walls, the area of the light emitting portion of the headlight can be increased even when the low beam is turned on.

In the invention according to claim 1 , the second reflecting surface is disposed on the front reflecting surface that reflects light from the high beam side LED light source forward and the extension portion that extends forward from the end of the front reflecting surface. And a third reflecting surface.

Can do. For this reason, it is possible to widen the light emitting region viewed from the front of the vehicle body relative to the vehicle coming from the front, and to reduce glare by reducing direct irradiation to the passing vehicle.

In the invention which concerns on Claim 2 , the partition is arrange | positioned so that it may overlap with an extension part by planar view. When the light that has passed through the light guide space from the low beam side LED light source is radiated forward on the third reflecting surface, a part of the light is reflected upward. There is a worry to let you. However, since the lower surface of the partition wall is provided with a fourth reflecting surface that irradiates light from the third reflecting surface forward, the light reflected upward by the third reflecting surface is also irradiated forward and the head The light emission area can be increased.

In the invention according to claim 3 , since the third reflecting surface and the fourth reflecting surface are configured by a diffuse reflecting surface that diffuses light, the light that has passed through the light guide space from the low beam side LED light source is third reflected. When light is guided to the surface, light is diffused by the third reflecting surface and the fourth reflecting surface, and direct irradiation to the field of view of the oncoming vehicle can be reduced. In addition, since the light diffuses, the light emitting region can be enlarged when viewed from the front or diagonally forward.

In the invention which concerns on Claim 4 , a 1st reflective surface and a partition are comprised separately, and light guide space is comprised by the front-end edge of a 1st reflective surface, and the rear-end edge of a partition. Since the front end edge of the first reflecting surface is provided below the rear end edge of the partition wall, more light that strikes other than the first reflecting surface can be guided to the light guide space. In addition, the light guide space can be easily configured by configuring the light guide space with the two parts of the first reflecting surface and the partition wall.

In the invention according to claim 5 , an engagement hole penetrating in the vertical direction is formed in at least one of the first substrate and the second substrate, and an engagement member is inserted in the engagement hole in the vertical direction so that the first At least one of the substrate and the second substrate is engaged with the reflector. In general, unlike a bulb, an LED light source has a small element and generates a small amount of heat as a light source element. Therefore, the distance from the reflector can be shortened, so that the deviation in irradiation in the vertical direction can be made relatively small. Temporarily, since the LED light source has high directivity, when the position irradiated on the reflector is shifted in the left-right direction, the irradiation angle toward the front of the vehicle moves to the left and right, and light cannot be guided in the intended direction. In this respect, in the present invention, the engaging member is inserted in the vertical direction, and even if the engaging member is loosened, the substrate only shifts in the vertical direction, so that the displacement in the horizontal direction can be restricted.

In the invention which concerns on Claim 6 , the hole which guides the light from a LED light source to a 1st reflective surface and light guide space is provided in the reflector under the LED light source provided in the 1st board | substrate. This hole has a hole shape along the first reflection surface and the light guide space, and is formed into a hole that is shaped so as to concentrate light on the first reflection surface and the light guide space. The amount of light hitting the light can be suppressed. For this reason, it can reduce that light is irradiated to directions other than the direction intended at the time of headlight lighting, enlarging a light emission area.

The partition wall 93 is formed integrally with the reflector, and a portion above the partition wall 93 is a low beam region, and a portion below the partition wall 93 is a high beam region. If the light source is constituted by a so-called bulb, the inside of the headlight 60 becomes hot, so it is necessary to convect air, and it is difficult to extend the partition wall 93 to the vicinity of the front lens 111. In this respect, since the light source is an LED light source (light emitting diode) in the present invention, heat is not generated as compared with the bulb, and the partition wall 93 can be extended to the vicinity of the lens 111.

  In the housing 61 having a substantially inverted triangular shape, the low beam region is located above the partition wall 93, so that the low beam region is widened in the vehicle width direction when viewed from the front, and the area of the low beam light emitting portion can be increased. it can.

The engagement member 84 is inserted into the engagement hole 83 in the vertical direction and engaged with the second mounting portion 85 of the reflector lower portion 91a. Yes.

  Thus, the engaging members 74 and 84 are inserted into the first substrate 72 and the second substrate 82 in the vertical direction. Even if the engaging members 75 and 85 are loosened, the substrates 72 and 82 are shifted in the vertical direction. Therefore, an effect of restricting the deviation of irradiation in the left-right direction can be obtained.

  On the first substrate 72, the left and right low beam side LED light sources 71, 71 are arranged to irradiate downward. The first reflecting surface 96 is bent so that the left and right portions are recessed, and reflects light from the left and right low-beam LED light sources 71 and 71 in a focused manner. That is, the left and right low-beam side LED light sources 71 and 71 are disposed mainly at positions where the first reflecting surface 96 is irradiated.

  The partition wall 93 is provided with a light guide space 90 that guides light emitted from the low beam side LED light source 71 to the second reflection surface 99 (high beam side reflection surface 99). Part of the light from the left and right low beam LED light sources 71 and 71 is guided from the light guide space 90 to the high beam region.

  On the second substrate 82, left and right high-beam LED light sources 81, 81 are arranged to irradiate downward.

Is provided. For this reason, more light that strikes other than the first reflecting surface 96 can be guided to the light guide space 90. By configuring the light guide space 90 with the two parts of the first reflecting surface 96 and the partition wall 93, the configuration of the light guide space 90 can be facilitated.

Next, attachment of the reflector lower portion 91a will be described.
As shown in FIG. 5, the reflector lower portion 91 a is fastened to the lower portion of the housing 61 by fastening members 62 and 62. The reflector lower portion 91a has a second substrate placement portion 82a on which the second substrate 82 is placed.

  The second substrate placement portion 82 a has a high beam side hole 82 b that guides light from the high beam side LED light source 81 to the second reflecting surface 99 below the high beam side LED light source 81 provided on the second substrate 82. Is provided. The high beam side hole 82 b has a hole shape along the second reflecting surface 99. By forming the high beam side hole 82b so as to be concentrated and guided to the second reflecting surface 99, the amount of light hitting other portions can be suppressed. For this reason, it can prevent that light is irradiated to directions other than the direction intended at the time of headlight lighting.

  The third reflecting surface 102 is a diffuse reflecting surface and has a so-called corrugated plate shape in which a plurality of substantially semicircular shapes continuous in a cross-sectional view extend in the longitudinal direction of the vehicle body, and thus can diffuse light. The diffuse reflection surface is not limited to this shape, and may be a diffuse reflection surface constituted by a plurality of protrusions instead of a uniform flat reflection surface.

Next, attachment of the reflector upper portion 91b will be described.
As shown in FIG. 6, the reflector upper portion 91 b is fastened to the upper portion of the housing 61 by fastening members 63 and 63. The reflector upper portion 91b has a first substrate placement portion 72a on which the first substrate 72 is placed.

  The first substrate placement section 72 a has a low beam that guides light from the low beam side LED light source 71 to the first reflecting surface 96 and the light guide space 90 below the low beam side LED light source 71 provided on the first substrate 72. A side hole 72b is provided. The hole 72 b on the low beam side has a hole shape along the first reflecting surface 96 and the light guide space 90. By forming the high beam side hole 72b so as to concentrate light in the first reflecting surface 96 and the light guide space 90, the amount of light hitting other portions can be suppressed. For this reason, it can prevent that light is irradiated to directions other than the direction intended at the time of headlight lighting.

Next, attachment of the reflector frame 91c will be described.
As shown in FIG. 7, the reflector frame portion 91 c is disposed in front of the reflector lower portion 91 a and the reflector upper portion 91 b and is fastened to the housing 61 by fastening members 64 and 64.

  The reflector upper portion 91 b has a first reflecting surface 96, and the front end edge 104 (lower end edge) of the first reflecting surface 96 is formed in an arc shape in accordance with the curved surface shape of the first reflecting surface 96. The reflector frame portion 91c has a partition wall 93 at the upper and lower intermediate portions, and the rear end edge 105 of the partition wall 93 is formed linearly on the left and right sides. The shape of the light guide space 90 is formed by matching the rear end edge 105 of the partition wall 93 with the front end edge 104 of the first reflecting surface 96. By using the light guide space 90 having such a shape, the light irradiated from the low beam side LED light source 71 (see FIG. 4) is guided to the first reflecting surface 96 and the light guide space 90, and light loss is reduced. can do. Further, since the shape of the light guide space 90 is simple, it can be manufactured easily.

The operation of the headlight 60 described above will be described next.
FIG. 8A is a view for explaining the traveling direction of light from the low beam side LED light source 71 in a side view of the vehicle. The light emitted from the low beam side LED light source 71 passes through the low beam side hole 72 b and is irradiated above the partition wall 93. Most of the light emitted from the low beam side LED light source 71 is reflected by the first reflecting surface 96 as shown by the arrow (1), and is irradiated forward and downward. As a result, the upper light emitting unit 122 above the partition emits light.

  Part of the light emitted from the low beam side LED light source 71 passes through the light guide space 90 and is irradiated below the partition wall 93. The light guided from the low beam side LED light source 71 to the light guide space 90 is reflected by the third reflecting surface 102 as indicated by an arrow (2), and further reflected by the fourth reflecting surface 103 as indicated by an arrow (3). Irradiated forward. As a result, the lower light emitting portion 121 below the partition wall 93 emits light.

  Thus, even when only the low beam side LED light source 71 is turned on, the light from the low beam side LED light source 71 can be guided from the light guide space 90 to the other light emitting region, and the other light emitting region can be turned on. . As a result, the entire headlight 60 divided by the partition wall 93 can be illuminated. In the headlight 60 in which the low beam region and the high beam region are divided by the partition walls, the area of the light emitting portion of the headlight 60 can be increased even when the low beam is on.

  In addition, since the light guide space 90 guides a part of the light emitted from the low beam side LED light source 71 to the third reflecting surface 102, the use of the front reflecting surface 101 is suppressed and the high beam irradiation range in the front is reduced. Prevent light guiding. For this reason, it is possible to suppress glare by reducing the direct irradiation to the passing vehicle while widening the light emitting area viewed from the front of the vehicle body when passing each other to ensure visibility. . Furthermore, the light reflected upward by the third reflecting surface 102 can also be irradiated forward by the fourth reflecting surface 103, so that the light emitting area of the headlight 60 can be increased and the visibility can be improved.

  FIG. 8B is a diagram for explaining the traveling direction of light from the high beam side LED light source 81 in a side view of the vehicle. The light emitted from the high beam side LED light source 81 passes through the high beam side hole 82 b and is irradiated below the partition wall 93. Further, the light from the high beam side LED light source 81 is reflected by the front reflecting surface 101 of the second reflecting surface 99 as shown by the arrow (4), and is irradiated in a substantially horizontal direction forward of the vehicle. As a result, the lower light emitting portion 121 below the partition wall 93 emits light.

  The motorcycle body cover structure of the present invention is applied to the scooter type vehicle in the embodiment, but is not limited to this, as long as it has a head ride in which a low beam region and a high beam region are separated by a partition wall, It may be applied to other general vehicles such as saddle riding type vehicles, tricycles, and four-wheel vehicles.

  In the embodiment, the upper side of the partition wall is an irradiation region by the low beam side LED light source, and the lower side of the partition wall is the irradiation region by the high beam side LED light source. However, the present invention is not limited to this, and the upper side of the partition wall is the high beam side LED light source. The lower side of the partition wall may be an irradiation area by the low beam side LED light source. Furthermore, the irradiation area by the low beam side LED light source and the irradiation area by the high beam side LED light source may be divided into left and right by a partition.

  Further, in the embodiment, the first substrate 72 is disposed on the upper portion of the reflector 91, irradiated downward from the low beam side LED light source 71 and reflected by the first reflecting surface 96, and the second substrate 82 is placed on the upper and lower intermediate portions of the reflector 91. However, the present invention is not limited to this. However, the present invention is not limited to this.
