[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicular lamp such as a high-mount stop lamp, and more particularly to a vehicular lamp capable of obtaining a highly accurate reflecting surface of a reflector.

[0002]

2. Description of the Related Art A conventional vehicle lamp of this type will be described with reference to FIGS. This example describes a high-mount stop lamp. In the drawings, reference numerals 1 and 2 denote a front housing and a rear housing. The front side housing 1 and the rear side housing 2 have a cover shape and are fitted and fixed to each other to form a horizontally long hollow body having an open bottom. The front housing 1
A horizontally long opening 10 is provided in the upper part of. In the figure, 3 is a lens. The lens 3 has a horizontally long shape, and has, for example, a fish-eye prism element group 30 on its inner surface. The lens 3 is fixed to the opening 10 of the front housing 1. As a result, a lamp chamber 31 is defined by the front housing 1, the rear housing 2, and the lens 3.
In the figure, reference numeral 5 denotes a valve holder. This valve holder 5 is connected to the front housing 1 and the rear housing 2.
And fixed in the lamp room 31 with a screw 52 or the like. The front housing 1, the rear housing 2, the lens 3, and the bulb holder 5 constitute a lamp body. In the figure, reference numeral 4 denotes a light source bulb.
The light source bulb 4 includes a glass bulb 40, a filament (not shown) disposed in the glass bulb 40, a base 41 integrally provided from the rear of the glass bulb 40, and an intermediate part of the base 41. And a flange portion 42 provided integrally with the portion.
The light source bulb 4 is detachably attached to the bulb holder 5, and a filament of the light source bulb 4 is positioned near a focal point F of a reflection surface 60 of a reflector 6, which will be described later. To be installed in
For example, three light source bulbs 4 are arranged side by side in the horizontal direction. The light source bulb 4 is connected to a power source (battery) via a foot brake switch.

In the drawing, reference numeral 6 denotes a reflector made of an elastic member such as a thin steel plate , that is, a metal lift.
Rector . This reflector 6 reflects the paraboloid of revolution.
And forming a reflecting surface portion 60 having a surface for example in drawing or the like, the lateral example 3 Konami設, and its reflective surface portion 60
Fixed portion 61 is substantially perpendicular to reflecting surface portion 60 from the lower end of
To be provided integrally. The fixing portion 61 of the reflector 6 is fixed to the bulb holder 5 with a screw 62, and the reflector 6 is disposed in the lamp room 31.
Note that the reflecting surface of the reflecting surface portion 60 previously subjected to aluminum vapor deposition. In addition to the above-described screw 62, the reflector 6 is provided with a pin integrally projecting from the valve holder 5, and the reflector 6 is fixed to the valve holder 5 by heat caulking the pin. Is also good. Thus, when applying the foot brake, the light source bulb 4 is lighted by a foot brake switch is a ON, the light from the light source bulb 4 is reflected by the reflecting surface of the reflective surface portion 60 of the reflector 6, the reflected light (Fig. A is radiated in front of the vehicular lamp (behind the vehicle) via the lens 3 to draw attention to the following vehicle. In such a vehicular lamp such as a high-mount stop lamp, it is necessary to form the reflecting surface of the reflecting surface portion 60 of the reflector 6 with high precision in light distribution.

[0004]

An invention to be Solved However, the conventional vehicle lighting device described above, the fixing portion 61 from the lower end of the reflecting surface portion 60
The reflecting surface is bent substantially at right angles to the reflecting surface portion 60 and
Because the the part 60 and the fixing portion 61 is to use metal Reflecting <br/> motor 6 without integral, bent portions of the reflecting surface portion 60 and the fixed portion 61 of the reflector 6, i.e. the boundary between The part (a in FIGS. 7 and 8) is bent almost at a right angle
Because are, by distortion and wrinkles or the like occurs in that portion, no reflective surface portion 60 of the high-precision reflector 6 is obtained. For example, the reflective surface portion 60 is formed first with high accuracy, then the fixed part 6
When attempting to form a 1, distortion and wrinkles occur on the reflecting surface 60 previously formed. High precision reflector reflection surface 6
There is a problem that it is difficult to obtain 0 . In addition, metal
Angle between the reflecting surface portion 60 and the fixing portion 61 of the reflector 6 made of
Cracks at the bent part
In some cases.

An object of the present invention is to provide a vehicular lamp in which a highly accurate reflector surface can be obtained.

[0006]

According to the present invention, there is provided a metal lift.
The light source bulb and the fixing part to be fixed to the lamp body.
A reflective surface that has a reflective surface that reflects
Provided between the launch surface and the fixed part, rise from the fixed part
A lighting device for a vehicle comprising a connecting plate portion;
A surface portion and the connecting plate portion are bent at an obtuse angle .

[0007]

According to the present invention, the reflecting surface of the reflector and the connecting plate are bent at an obtuse angle by the above configuration .
Even if the reflector is made of metal,
To minimize the occurrence of distortion, wrinkles, cracks, etc.
As a result, a highly accurate reflecting surface of the reflector can be obtained.

[0008]

FIG. 1 shows an embodiment of a vehicular lamp according to the present invention.
This will be described with reference to FIGS. This example describes a high-mount stop lamp. 5 to FIG.
The same reference numerals indicate the same items. In the figure, 64 is a connecting plate portion formed integrally between the reflecting surface portion 60 and the fixed portion 61 of the reflector 6. The connecting plate 64 is provided on the reflecting surface 6.
0 from the lower edge to the reflecting surface 60 at an obtuse angle of approximately 180 °
It is bent. The connecting plate 64 is fixed
It is bent substantially at right angles to the fixed portion 61 (fixed
Part 61).

The vehicular lamp according to the present invention in this embodiment has the above-described structure , that is, the reflecting surface portion of the reflector 6.
60 and the connecting plate 64 at an obtuse angle of approximately 180 ° (for example,
(Reflected shape)
Is made of metal, the reflective surface portion 60 and
A bent portion with the connecting plate portion 64 (see FIG. 3 and FIG.
At the boundary indicated by the arrow), distortion, wrinkles, cracks, etc.
It can be suppressed as much as possible. As a result, high-precision reflation
The reflection surface portion 60 of the denter 6 is obtained.

The connecting plate 64 reflects the reflection of the reflector 6.
Since it is provided between the surface part 60 and the fixing part 61,
Of the boundary between the connecting plate portion 64 and the fixing portion 61 is substantially at a right angle.
The connecting plate portion 64 and the fixing portion 61
At the boundary between the two, such as distortion and wrinkles during bending
Even if cracks occur, the distortion, wrinkles, etc.
And is not absorbed by the reflection surface portion 60. This result
As a result, the connecting plate portion 64 and the fixing portion 61 are bent at substantially right angles.
Even if it is, distortion and wrinkles do not occur on the reflection surface portion 60,
A highly accurate reflecting surface 60 of the reflector 6 is obtained.

In the above-described embodiment, the high mount stop lamp has been described. However, the present invention can be applied to a vehicular lamp other than the high mount stop lamp.

[0012]

[Effects of the Invention] As is apparent from the above, the vehicle lighting device of the present invention has an obtuse angle between the reflecting surface of the reflector and the connecting plate.
Since it is bent, the reflector is made of metal
Even if there is any distortion, wrinkles, cracks, etc. in the bent part
Can be suppressed as much as possible, and as a result, a highly accurate reflecting surface portion of the reflector can be obtained.
