Abstract

(57) [Abstract] [Purpose] In the conventional headlight, when it is specified that no dazzling light is generated even with this headlight alone, a lamp interior decoration frame only for satisfying the specification is provided. There is a problem that the production process is complicated, such as setting and assembling must be performed, and it is necessary to properly use the interior decoration frame of the lamp in a destination not specified above. According to the present invention, a headlight is provided with a stripe knurl 5 along the irradiation direction of the headlight 1 at a position facing the reflected light from the reflecting mirror 3 on the lower side 4a of the interior decoration frame 4 of the lamp. By setting 1, the dazzling light is diffused by the scoring knurls 5 to be within the standard value even for the destination where the measurement of the headlight 1 alone is required, and the interior decoration frame of the lamp with other destinations is set. This makes it possible to simplify the production process by eliminating the need for proper use, and solves the problem.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicular lamp, and more particularly, to a structure of a headlight that is configured to aim by moving a reflecting mirror.

[0002]

[Prior art]

 FIG. 5 shows an example of the configuration of a conventional headlight 90 of this type. A reflecting mirror 92 is installed in the housing 91 so that the irradiation direction can be changed vertically and horizontally. 93 is fixed to the housing 91 side. At this time, when the reflecting mirror 92 is a compound reflecting mirror whose light distribution characteristics can be set, the lens 93 is almost transparent, so that a frame shape is formed in front of the reflecting mirror 92. The formed lamp interior decoration frame 94 is provided, and the lamp interior decoration frame 94 is supposed to be subjected to a glitter treatment by aluminum vapor deposition or the like in order to have a unified feeling with the reflection mirror 92.

[0003]

[Problems to be solved by the device]

 However, in the above-described conventional headlamp 90, since the reflecting mirror 92 is movable and the lamp interior decoration frame 94 is fixed, the mutual positional relationship changes when aiming, and the light from the reflecting mirror 92 changes. Is reflected on the interior decoration frame 94 of the lamp interior and causes stray light. Especially, when reflected on the lower side at 94a, the reflected light becomes upward and may become dazzling light to an oncoming vehicle.

Normally, it is considered that the above possibility does not occur in practical use by providing the downward inclination angle α on the lower side. However, depending on the specification of the destination, it may not be generated in a state where the vehicle is mounted on an automobile. In some cases, it is stipulated that the headlight 90 alone does not generate dazzling light. In such a case, if the reflecting mirror 92 is turned downward as much as possible, dazzling light will be generated, and the standard will be met. In order to do so, there is no choice but to prepare a lamp interior decoration frame or the like with a larger inclination angle α and assemble it for each destination, which complicates the production process and increases costs. However, the solution to this point has become an issue.

[0005]

[Means for Solving the Problems]

 The present invention is, as a concrete means for solving the above-mentioned conventional problems, a lamp in which a reflecting mirror is moved to perform aiming, and a lamp interior decoration frame subjected to a glitter treatment is provided in front of the reflecting mirror. In a fixed headlight, a line crease is provided along the irradiation direction of the headlight at a position facing the reflected light from the reflecting mirror on the lower side of the lamp interior decoration frame. The problem will be solved by providing a headlight.

[0006]

【Example】

 Next, the present invention will be described in detail based on an embodiment shown in the drawings. Reference numeral 1 in FIG. 1 denotes a headlight, which is installed in a housing 2 so that a reflecting mirror 3 can aim, and in front of the reflecting mirror 3, a lens 8 is provided. The lighting interior decoration frame 4 that has been subjected to the glitter treatment is fixedly installed, and the positional relationship with the lighting interior decoration frame 4 is changed by moving the reflecting mirror 3 for aiming. This is the same as the conventional example.

However, according to the present invention, the crease knurls 5 are provided on the lower side 4a of the lamp interior decoration frame 4 at the position facing the reflected light from the reflecting mirror 2, and the crease knurls 5 are the creases. The direction is substantially along the irradiation direction of the headlight 1, and the cross-sectional shape is formed as a V groove shape as shown in FIG. 2, for example.

Next, the operation and effect of the present invention having the above-mentioned structure will be described. The aiming of the reflecting mirror 3 is directed downward, and the reflected light is reflected on the lower side 4 a of the interior decoration frame 4 of the lamp. When reflected, the reflected light becomes diffused light by the streak knurls 5, and the attenuation rate for a predetermined distance increases as compared with the case where the lower side 4a is flat.

This means that when the headlight 1 is viewed from the front of a predetermined distance, the illuminance (luminance) of the upward light emitted is attenuated, and this illuminance is below a predetermined value. No dazzling will occur. Therefore, the illuminance (luminous intensity) of the upward light emitted can be set by appropriately setting the pitch or the V-groove angle when the linear knurls 5 are applied to the lower side 4a of the interior decoration frame 4 of the lamp chamber. It is possible to make it less than or equal to the standard value specified in the standard, etc., and it is possible to set it as one that does not generate dazzling light both legally and practically.

FIGS. 3 and 4 show another embodiment of the present invention. As is apparent from the above description, the crease knurls formed on the lower side 4a should have a function of diffusing light. The cross-sectional shape is not limited to the V-groove shape as described in the previous embodiment. Accordingly, as shown in FIG. 3, the convex knurled knurl 6 may be used, or as shown in FIG. 4, the concave knurled knurl 7 may be used, and in short, the necessary amount of diffusion action can be obtained. Then, the shape does not matter.

[0011]

[Effect of device]

 As described above, according to the present invention, the headlight is provided with the streak knurling along the irradiation direction of the headlight at the position facing the light reflected from the reflecting mirror on the lower side of the interior decoration frame of the lamp. Therefore, by setting the reflector to the maximum downward when measuring the headlight alone, even when the reflected light from the reflector directly reflects on the lower side of the interior decoration frame of the lamp to generate dazzling light, The dazzling light is diffused by the above-mentioned streak knurls so that it falls within the specified value.For example, even in the specification where the dazzling light measurement by the headlight alone is specified, it can be passed, and a dedicated lamp room for that purpose This eliminates the use of decorative frames, etc., and is extremely effective in simplifying the production process and reducing costs.
