Description

  The present invention relates to a vehicular lamp having two lamp functions in one lamp unit.

  This type of vehicular lamp is conventionally known (for example, Patent Document 1). Hereinafter, a conventional vehicle lamp will be described. A conventional vehicle lamp is a projector-type lamp, and includes a reflector, a bulb attached to the reflector, and a convex lens. The reflector has a single reflecting surface based on an ellipse. The bulb has a bulb axis arranged in the direction of the reflecting surface and the optical axis of the convex lens, and has a main filament, a subfilament, and a shade. The main filament and the subfilament are arranged in series in the valve axis direction, the main filament is located on the rear side, the subfilament is located on the front side, and the shade is located on the upper side of the subfilament. Adjacent to. The first focal point of the reflecting surface is located between the main filament and the subfilament.

  Hereinafter, the operation of the conventional vehicle lamp will be described. When the main filament is turned on, the light radiated from the main filament is reflected by the reflecting surface, condensed on one of the two focal points of the reflecting surface, and travels outside through the convex lens. Irradiated as a light distribution pattern. When the subfilament is turned on, light emitted from the upper side of the subfilament is shielded by the shade. On the other hand, the light emitted from the lower side of the subfilament is reflected by the reflecting surface, condensed on the second focal point of the reflecting surface, and irradiated to the outside as a passing light distribution pattern through the convex lens.

  However, since the conventional vehicular lamp is composed of a single reflecting surface, only a single light distribution pattern of the traveling light distribution pattern can be obtained when the main filament is turned on. A light pattern cannot be obtained. In addition, the conventional vehicular lamp can adjust the light amount (light flux, luminous intensity, illuminance) of the passing light distribution pattern by the shade, but cannot adjust the light amount of the traveling light distribution pattern. Further, in the conventional vehicular lamp, since the bulb is arranged in the direction of the optical axis of the reflecting surface and the convex lens, the dimension in the depth direction becomes large, and the layout flexibility of the lamp is limited.

Then, a portion of the light emitted from the subfilament 8 that enters the main reflecting surface 4 is shielded by the shade 9. On the other hand, a part of the light emitted from the subfilament 8 that is not shielded by the shade 9 is incident on the sub-reflection surface 5 and reflected. As shown in FIG. 5, the reflected light is irradiated in front of the automobile C as a daytime lamp light distribution pattern DP.

A traveling light distribution pattern HP when the main filament 7 is lit and a wide light distribution pattern WP on both the left and right sides are shown.

  The vehicular lamp in this embodiment is configured and operated as described above, and the effects thereof will be described below.

  Since the vehicular lamp in this embodiment, that is, the headlamps 1L and 1R, is composed of a composite reflecting surface of a main reflecting surface 4 and a sub-reflecting surface 5, as shown in FIGS. When the filament 7 is lit, a main light distribution pattern HP as a main light distribution pattern of one lamp function is formed by the main reflection surface 4, and a sub light distribution pattern of one lamp function is formed by the sub reflection surface 5. Wide light distribution pattern WP, which is located from the left and right ends of the travel light distribution pattern HP to the outside, is formed. As described above, the vehicular lamp according to this embodiment has a light distribution pattern having a single lamp function, which is a combination of the travel light distribution pattern HP having the main light distribution pattern and the wide light distribution pattern WP having the sub light distribution pattern. Since it is obtained as a light distribution pattern, it is possible to meet the needs of various light distribution patterns and to contribute to traffic safety.

  Further, the vehicular lamp according to this embodiment adjusts the size and shape of the main reflection surface 4, the sub reflection surface 5, and the shade 9, for example, by adjusting the main reflection surface 4, the sub reflection surface 5, and the shade 9. Or by rotating and adjusting the bulbs 2L and 2R around the bulb axis ZB-ZB, the light quantity of the running light distribution pattern HP of the main light distribution pattern of one lamp function and the sub light distribution pattern The light amount of the wide light distribution pattern WP and the light amount of the day type lamp light distribution pattern DP of the light distribution pattern of other lamp function can be arbitrarily and optimally adjusted and distributed.

  Furthermore, the vehicular lamp according to this embodiment forms a travel light distribution pattern HP of a main light distribution pattern of one lamp function on the main reflection surface 4, and other lamp functions on the sub reflection surface 5. Since the light distribution pattern DP for the daytime lamp having the light distribution pattern is formed, it is possible to obtain the minimum amount of the light distribution pattern DP for the daytime lamp and to obtain the maximum necessary light distribution pattern HP. The amount of light can be obtained. In addition, the vehicular lamp according to this embodiment reflects the light radiated from the main filament 7 by the main reflecting surface 4 to form the traveling light distribution pattern HP of the main light distribution pattern of one lamp function, In addition, a wide light distribution pattern WP having a sub light distribution pattern of one lamp function is formed by reflecting on the sub reflective surface 5, while the light emitted from the subfilament 8 is reflected on the sub reflective surface 5 and the like. Since the light distribution pattern DP for the daytime lamp having the light distribution pattern of the lamp function is formed, each of the light distribution patterns HP, WP, DP can be controlled easily and reliably.

  Furthermore, in the vehicular lamp according to this embodiment, since the shade 9 is located on the rear side of the subfilament 8, the subsurface 8 is turned on by the reflecting surface 12 facing the subfilament 8 of the shade 9. The light directly emitted from the filament 8 (direct light) and the light emitted from the subfilament 8 and reflected by the reflecting surface 12 of the shade 9 (shade reflected light) can be used effectively, and other lamps can be used. The light quantity of the daytime lamp light distribution pattern DP of the functional light distribution pattern can be increased, which can contribute to traffic safety.

  FIG. 9 is a partial longitudinal sectional view showing a modification of the vehicular lamp according to the embodiment. The vehicular lamp according to this modified example has the sub-reflecting surface 5 as the main reflecting surface, whereas the vehicular lamp according to the above embodiment has the sub-reflecting surface 5 positioned above the main reflecting surface 4. 4 is located on the lower side. The vehicular lamp according to this modified example can achieve substantially the same function and effect as those of the vehicular lamp according to the above-described embodiment.

However, in the present invention, as a main light source and a sub light source of a bulb, in addition to a double filament, for example, a gas discharge light source such as a high pressure metal vapor discharge lamp such as a metal halide lamp, a high intensity discharge lamp (HID bulb), etc. A double arc of a discharge lamp or a self-luminous semiconductor light source such as an LED or an EL (organic EL) may be used.

  Further, in the above-described embodiment, the valves 2L and 2R are arranged so as to be substantially orthogonal to the left and right horizontal with respect to the optical axes ZL-ZL and ZR-ZR of the main reflecting surface 4. However, in the present invention, as long as the bulb is arranged so as to be substantially orthogonal to the optical axis of the main reflecting surface, it does not have to be arranged horizontally.

  Further, in the above embodiment, the main light distribution pattern of one lamp function is the traveling light distribution pattern HP, the sub light distribution pattern of one lamp function is the wide light distribution pattern WP, and the other lamps. The functional light distribution pattern is the daytime lamp light distribution pattern DP. However, in the present invention, the main light distribution pattern and the sub light distribution pattern of one lamp function and the light distribution pattern of another lamp function are the light distribution pattern HP for travel, the light distribution pattern for wide WP, and the distribution for daytime lamps. A light distribution pattern other than the light pattern DP may be used.

  Furthermore, in the said Example, headlamp 1L, 1R is demonstrated. However, in the present invention, other vehicle lamps such as fog lamps and swivel lamps may be used.
