This vehicular lamp includes a reflector 6A having a reflecting surface (60U, 60C, 60D) and an opening 68, and a light source (not shown). The reflector 6A and the light source are arranged in a lamp chamber defined by a lamp housing and a lamp lens (not shown).

In the above vehicle lamp, the light distribution control is mainly performed by the reflecting surface (60U, 60C, 60) of the reflector 6A.
D). To this end, the reflecting surface is divided into a plurality of vertically long segments 60U, 60C, 60D, and the plurality of segments 60
The surface (reflection surface) of U, 60C, and 60D is formed by a free curved surface so that a predetermined light distribution characteristic can be obtained.

In the example of FIG. 9, the plurality of segments 60U, 60C, 60D are divided into three stages of upper, middle and lower. The surfaces of the plurality of segments 60U on the upper stage side have a convex shape (cylindrical convex curved surface). Also,
The surfaces of the plurality of segments 60D on the lower stage side have a concave shape (cylindrical concave curved surface). Furthermore, the surfaces of the plurality of segments 60C on the middle stage side have a convex shape or a concave shape.

The 30 segments 60U, 60C,
A connecting surface 64 is formed at the end of 60D, that is, the surface of the end that does not affect the light distribution characteristics. This connecting surface 64
Is formed by a gradually changing surface that gradually changes so that the convex and / or concave shape of the surface of the segments 60U, 60C, 60D substantially matches the shape of the opening 68, that is, the inner surface 62I of the standing wall 62. .

Hereinafter, the connecting surface 64 will be described in more detail with reference to FIG. The connecting surface 64 is formed of a curved surface having a predetermined radius of curvature R that connects a point 66 at a predetermined height H from the bent portion 63 and a point 67 at a predetermined length L from the bent portion 63. The predetermined height H, the predetermined length L, and the radius of curvature R differ depending on the segments 60U, 60C, and 60D.

The point 66 at the predetermined height H corresponds to the end that does not affect the light distribution characteristics of the lower segment 60D. That is, the portion up to the point 66 at the predetermined height H of the lower-side segment 60D is an effective reflection surface. In addition, the point 67 at the predetermined length L
Corresponds to the middle of the standing wall 62.

A plurality of knurls 65 for preventing glare light are provided between the end of the connecting surface 64 of the inner surface 62I of the standing wall 62 (the point 67 at the predetermined length L) and the opening 68. ing. As shown in FIG. 3, the plurality of knurls 65 have substantially the same pitch P and height h.
Have and. The surface of the knurl 65 has a convex shape (cylindrical convex curved surface). Further, the pitch P on the lower side of the knurl 65 and the segment 6 on the lower stage side
The pitch of 0D is almost the same.

As shown in FIGS. 1, 4 and 5, the lower standing wall 62 of the standing walls 62 is longer than the other standing walls 62. This is because in the case of the headlamp 1 of this example in which the lamp lens 3 slants greatly from the upper surface to the front surface, an optical axis adjusting mechanism, a breathing mechanism, a wiring mechanism, etc. arranged from the lamp lens 3 to the rear portion of the reflector 6. It is for hiding so that it cannot be seen. The length of the standing wall 62 is a streamlined type of the vehicle body,
That is, it changes according to the size of the slant of the lamp lens 3.

As shown in FIGS. 4 and 5, the lamp chamber 4
Inside, an inner panel (or inner housing or extension) 7 is arranged. The inner panel 7 hides internal structures from the lamp lens 3, such as an optical axis adjusting mechanism, a breathing mechanism, and a wiring mechanism arranged behind the reflector 6 in the lamp chamber 4 invisible. is there. It also prevents light from leaking in directions other than a predetermined direction. The outer surface and the inner surface of the inner panel 7 are coated with silver color or aluminum.

The lower surface 71 of the inner panel 7
A knurl (not shown) is provided on the inner surface of the. The pitch of the knurls of the inner panel 7, the pitch P of the knurls 65 of the reflector 6 and the pitches of some of the segments 60U, 60C, 60D substantially match.

In the headlamp 1 according to the first embodiment, a light source bulb of another lamp, in this example, a clearance lamp, may be attached. Further, there may be a case where a breathing structure portion (not shown) for performing breathing between the inside of the lamp chamber 4 and the outside is provided.

(Explanation of Operation and Effect of First Embodiment) The headlamp 1 according to the first embodiment has the above-mentioned configuration, and its operation and effect will be described below.

When the halogen lamp 5 which is the light source bulb of the headlamp 1 is turned on, the light from the halogen lamp 5 is reflected by the reflecting surface (60U, 60C, 60D) of the reflector 6.
And is controlled by a predetermined low beam or high beam light distribution pattern. The controlled reflected light passes through the lamp lens 3 and is emitted to the outside, that is, in front of the automobile in a predetermined low beam or high beam light distribution pattern. The low beam and the high beam can be switched by a switch operation.

Headlamp 1 according to the first embodiment
As shown in FIG. 1 (A), the connecting surface 64 ensures that the surface convex shape and / or concave shape of the segments 60U, 60C, 60D substantially match the shape of the inner surface 62I of the basic thickness of the opening 62. Change gradually, segment 60U,
The end shapes of 60C and 60D are the inner surface 62I of the opening 62.
It almost matches the shape. Therefore, in the refraction portion 63 at the boundary between the reflection surface portion 61 of the reflector 6 and the standing wall 62,
The concavo-convex shape at the ends of the segments 60U, 60C, 60D disappears, and the shape becomes the inner side surface 62I of the opening 62, improving the appearance.

In the headlamp 1 according to the first embodiment, the reflecting surface (60U, 60C,
Since the light distribution is controlled by 60D), the lamp lens 3 uses a plain outer cover. Therefore, in the headlamp 1 according to the first embodiment, the lamp chamber 4 is passed through the transparent lamp lens 3.
I can see the inside. In particular, since the line of sight of the headlamp 1 from the human eye is from diagonally above to diagonally below, the lower reflecting surface (60D) of the reflecting surfaces (60U, 60C, 60D) of the reflector 6A in the lamp chamber 4 is shown. Looks good.

On the other hand, in the headlamp 1 according to the first embodiment, as described above, the concave shape at the end of the lower segment 60D disappears due to the connecting surface 64.
This is optimum in the case of a headlamp in which the front shape of the reflector 6 is circular and the surface shape of the lower-stage segment 60D is concave, and the concave shape of the end of the lower-stage segment 60D is emphasized. .

Further, in the headlamp 1 according to the first embodiment, the reflector 6 has a circular shape, and the slant of the lamp lens 3 causes the lower standing wall 62 of the reflector 6 to have an opening 68 further than the connecting surface 64. The inner surface 62I of the standing wall 62 is provided with aluminum vapor deposition or silver coating for a reflecting surface dummy. Therefore, a concave mirror is formed on the inner surface 62I of the standing wall 62 below the reflector 6 as if it were a concave mirror. Therefore, if it is left as it is, the light from the halogen lamp 5 may be reflected by the concave mirror and concentrated at almost one point to become glare light.

On the other hand, in the headlamp 1 according to the first embodiment, the glare light is emitted by the knurls 65 provided between the end of the connecting surface 64 of the inner surface 62I of the standing wall 62 and the opening 68. It can be surely prevented.

(Explanation of Second Embodiment) FIG. 6 shows a second embodiment of the vehicular lamp according to the present invention. In the figure,
5 and 9 have the same reference numerals.

In the headlamp according to the second embodiment, the length of the lower standing wall 62 is shorter than that of the headlamp 1 according to the first embodiment, depending on the size of the slant of the lamp lens. It is a thing. That is, the lower standing wall 62 has a length up to the end of the connecting surface 64 and a length from the bent portion 63 to a point 67 at a predetermined length L. Therefore, in the headlamp according to the second embodiment, there is no part of the lower standing wall 62 from the end of the connecting surface 64 to the opening 68, and therefore there is no knurl 65 provided in that part. In addition,
The headlamp according to the second embodiment can achieve substantially the same operational effect as the headlamp 1 according to the first embodiment.

Further, in the headlamp according to the second embodiment, the opening 6 is formed from the middle of the standing wall 62 of the connecting surface 64.
Up to 8, a plurality of convex surfaces having substantially the same height may be formed. For example, when the reflector is viewed from the direction of the arrow in FIG. 6, a convex surface similar to that of the knurl 65 shown in FIG. 3 is formed.

As a result, the headlamp according to the second embodiment has a circular front shape due to the plurality of convex surfaces, and in the case of the reflector 6 having the standing wall 62, the light from the halogen lamp 5 stands up. It is possible to reliably prevent the glare light from being reflected by the inner surface of 62 and concentrating at almost one point. Further, in the headlamp according to the second embodiment, the plurality of convex surfaces have substantially the same height, so that the appearance is improved. In addition, this Embodiment 2
The plurality of convex surfaces having substantially the same height may be formed between the end (point 67) of the connecting surface 64 of the first embodiment and the middle of the connecting surface 64.

This connecting surface 64
Is provided between the end point 66 of the effective reflection surface of the segment 60D and the opening 68. The connecting surface 64 is the headlamp 1 according to the first embodiment.
Similarly to the above, the concave surface of the segment 60D is formed by a gradually changing surface that gradually changes so as to substantially match the inner wall shape of the basic thickness of the opening 68. As a result,
The headlamp according to the third embodiment can achieve substantially the same effect as the headlamp 1 according to the first embodiment.

(Description of Fourth Embodiment) FIG. 8 shows a fourth embodiment of the vehicular lamp according to the present invention. In the figure,
7 and 9 have the same reference numerals.

The headlamp according to the fourth embodiment is different from the headlamp 1 according to the first embodiment in that the reflector 600 has a substantially oblong shape, not a circular shape. That is, the upper and lower openings 680 of the reflector 600 form a horizontal plane. The connecting surface in this case is formed by a gradually changing surface that gradually changes so that the surface convex shape and / or concave shape of the segments 60U, 60C, 60D substantially match the inner planar shape of the basic thickness of the opening 680. There is. As a result, the headlamp according to the fourth embodiment can achieve substantially the same operational effect as the headlamp 1 according to the first embodiment.

In the headlamp according to the fourth embodiment, the knurl 65 shown in FIG. 3 may be provided on the inner surface of the opening 680 forming the horizontal plane of the reflector 600.

(Explanation of Examples Other Than Embodiments) In the headlamps according to the first to fourth embodiments, the segments 60U, 60C and 60D are vertically long.
The division shape of the segment is not particularly limited.

Although the first to fourth embodiments have described the headlamps that illuminate the front of the vehicle, the present invention describes fog lamps other than the headlamps, bend lamps and cornering lamps that illuminate the sides of the vehicle. ,
The present invention can be applied to a back lamp that illuminates the rear of an automobile and a vehicular lamp such as a signal light.
