[Prior art]
Hereinafter, a conventional vehicle lamp of this type will be described with reference to FIGS. This example describes a vehicular lamp that is a cornering lamp mounted on the front left side of an automobile, and in which the lamp housing and the reflector are integrated. In the drawings, HH is a horizontal axis, VV is a vertical axis, U is an upper side when looking forward from the driver seat, D is a lower side when looking forward from the driver seat, and L is a driver seat. The left side when looking forward from the left side, and R the right side when looking forward from the driver's seat. In the drawings, hatching is omitted for understanding the drawings.
[0003]
In the figure, reference numeral 1 denotes a lamp housing integrated with a reflector. An opening 10 is provided from the front surface of the lamp housing 1 to the side surface (left side surface in this example). On the other hand, a mounting cylindrical portion 11 is integrally provided on the left side of the rear portion of the lamp housing 1.
[0004]
A lens (outer lens) 2 is disposed in the opening 10 of the lamp housing 1 by a sealant or an adhesive (for example, hot melt), and the lamp chamber 3 is defined by the lens 2 and the lamp housing 1. Formed.
A lens element (a so-called prism) 20 is provided on the inner surface of the lens 2 (the surface facing the lamp chamber 3) to refract and diffuse reflected light from the reflecting surface 5 described later.
The lens 2 described above uses a single refracting / diffusing lens, but a double lens in which a plain lens is combined with the refracting / diffusing lens may be used.
[0005]
A light source bulb 4 is disposed in the lamp chamber 3 described above. In the light source bulb 4, a cylindrical filament 41 is enclosed in a glass bulb 40, and this filament constitutes a light emitting section. The light source bulb 4 is detachably attached to a socket 42, is detachably attached to the mounting cylinder portion 11 of the lamp housing 1 via the socket 42, and is in a predetermined position (that is, in the lamp chamber 3). The center of the filament 41 is disposed at a position near the focal point F of the reflecting surface 5 described later.
Here, the filament 41 is arranged in a horizontal direction with the axis of the filament 41 perpendicular to the axis BB of the light source bulb 4.
[0006]
On the inner surface of the lamp housing 1 (the surface facing the lamp chamber 3), a reflecting surface 5 for reflecting light from the light source bulb 4 toward the lens 2 is provided by aluminum vapor deposition or the like. The reflecting surface 5 in this example forms a paraboloid of revolution having an optical axis (reflecting surface axis) ZZ as a rotation axis.
[0007]
In this vehicular lamp, as shown in FIG. 7, the reflection surface axis ZZ is at an angle θ1 (normally 40 to 45 °) in the left direction (counterclockwise in FIG. 7) with respect to the vehicle axis AA. And the light source bulb axis BB is directed leftward (counterclockwise in FIG. 7) by an angle θ2 with respect to the vehicle axis AA. As a result, the left direction of the reflecting surface axis ZZ And the leftward direction of the light source bulb axis BB differ by an angle θ1-θ2.
[0008]
When the filament 41 of the light source bulb 4 is turned on, as shown in the optical path diagram of FIG. 9, the center of the filament 41 (the point where the reflecting surface axis ZZ and the light source bulb axis BB intersect) F The light is reflected at points C and D where the reflecting surfaces 5, 51 and 52 are present, and becomes reflected light L1 and L2 parallel to the reflecting surface axis ZZ. On the other hand, the light from the left end FL and the right end FR of the filament 41 is reflected at points C and D where the reflecting surfaces 5, 51 and 52 are present, and is reflected with respect to the reflected lights L1 and L2 parallel to the reflecting surface axis ZZ. The inner reflected lights L1L and L2L and the outer reflected lights L1R and L2R respectively. The reflected lights L1, L1L, L1R, L2, L2L, and L2R are refracted and diffused through the lens 2 and radiated to the outside as a refracted diffused light with a predetermined light distribution pattern.
[0009]
[Problems to be solved by the invention]

An ideal light distribution pattern indicated by a broken line in (B) is obtained.
[0010]
However, in the above-described conventional cornering lamp vehicle lamp, as shown in FIG. 7, in order to escape from interference with the vehicle body (not shown), and due to restrictions in the die-cutting direction, the orientation of the reflecting surface axis ZZ And the direction of the light source bulb axis BB cannot coincide with each other, and the light source bulb axis BB is oriented to the angle θ1-θ2 in the right direction (clockwise in FIG. 7) with respect to the reflecting surface axis ZZ. There are many cases.
In this case, as shown in the optical path diagram of FIG. 9, the above-described conventional vehicle lamp is different in the left direction of the reflection surface axis ZZ and the left direction of the light source bulb axis BB. Reflective surface 5 (as shown in FIG. 10, the same reflective surface as the reflective surface 5 in which the direction of the reflective surface axis ZZ and the direction of the light source bulb axis BB match and an ideal light distribution pattern is obtained. 5), the reflected light L1 ′ in FIG. 10 in which an ideal light distribution pattern is obtained by the spread width of the reflected light L1, L1L, L1R on the first reflective surface 51 on the left side L with respect to the reflective surface axis ZZ. , L1′L and L1′R are wider than the spread width. Further, the reflected light L2 ', L2' in FIG. 10 in which the spreading width of the reflected light L2, L2L, L2R on the second reflecting surface 52 on the right R with respect to the reflecting surface axis ZZ can be obtained. It is narrower than the spread width of L and L2′R.
As a result, the ideal light distribution pattern indicated by the broken lines in FIGS. 11A and 11B cannot be obtained, and the blurred light distribution with many glares indicated by the solid lines in FIGS. 11A and 11B. It becomes a pattern.
[0011]
In addition, 15 ° L, 25 ° L, 40 ° L, 55 ° L, and 65 ° L in FIG. 11B are 15 °, 25 °, 40 °, and 55 ° on the left side with respect to the vehicle axis AA. , 65 ° position.
[0012]
12A and 12B are explanatory views showing a blurred light distribution pattern with a lot of glare in the above-described conventional vehicle lamp, and FIG. 12A is a front view showing a state in which a lens is removed. ) Is a light distribution pattern image projected from a reflecting surface directly to a screen perpendicular to the reflecting surface axis without using a lens.
As shown in (A), a plurality of small regions (portions surrounded by dotted lines) A, B, 1C, 2C, 1D, 2D, 1E, 2E, the first reflecting surface 51 and the second reflecting surface 52, In the case where 1F, 2F, 1G, and 2G are provided symmetrically with respect to the vertical axis V-V, the small areas A, B, 1C, 2C, 1D, 2D, 1E, 2E, 1F, 2F, 1G, A 2G light distribution pattern is obtained as shown in FIG. That is, the light distribution pattern of the small areas 1C, 1D, 1E, 1F, and 1G on the first reflecting surface 51 side spreads as described above, and the small areas 2C, 2D, 2E, 2F, and 2G on the second reflecting surface 52 side. The light distribution pattern is narrowed as described above.
Thus, as is apparent from the explanatory diagram of FIG. 12, the above-described conventional vehicle lamp has a blurred light distribution pattern with many glares as shown in FIG.
[0013]
An object of the present invention is to provide a vehicular lamp that can obtain an ideal light distribution pattern.
[0014]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention sets the light source bulb axis side of the reflection plane as a first reflection plane with respect to the reflection plane axis, and sets the opposite side of the reflection plane axis as the light source bulb axis. The second reflecting surface is a virtual rotating paraboloid that provides an ideal light distribution pattern when the reflecting surface axis coincides with the light source bulb axis, and the first reflecting surface has a focal length. The second reflecting surface has a focal length that is greater than the focal length of the virtual rotating paraboloid and has a focal point that matches the focal point of the virtual rotating paraboloid. It is characterized by being composed of a rotating paraboloid which is smaller than the focal length of the virtual rotating paraboloid and whose focal point coincides with the focal point of the virtual rotating paraboloid.
[0015]
As a result, the vehicular lamp of the present invention spreads the reflected lights L3, L3L, and L3R on the first reflecting surface 61 as shown in FIGS. 3 (A) and 3 (B) and FIGS. 4 (A) and 4 (B). The width is narrower than the spread width of the reflected lights L1, L1L, and L1R on the virtual paraboloids 5 and 51, and approaches the spread width of the reflected lights L1 ′, L1′L, and L1′R to obtain an ideal light distribution pattern. Further, the spread width of the reflected lights L4, L4L, and L4R on the second reflecting surface 62 is wider than the spread width of the reflected lights L2, L2L, and L2R on the virtual paraboloidal surfaces 5 and 52, and an ideal light distribution pattern is obtained. It approaches the spreading width of the reflected light L2 ', L2'L, L2'R. For this reason, an ideal light distribution pattern can be obtained even if the horizontal direction of the reflecting surface axis is different from the horizontal direction of the light source bulb axis.
