  However, the vehicular lamp provided with these conventional daytime running lamps has the following problems.

  That is, when a daytime running lamp is provided as a separate lamp at a position away from the headlamp as in the case of a conventional vehicle lamp, a limited space given as a lamp arrangement space in the vehicle is used. It was difficult to place.

  Specifically, if daytime running lamps are required to be installed in the future, there will be a space to install a movable lamp for AFS (Adaptive Front-Lighting System), and the headlamp will be the driving beam. It is expected that it will be difficult to use a four-lamp headlight that is divided into two types of light distribution.

  In particular, in vehicles supplied to countries all over the world, when the housing and appearance (extensions, etc.) of the vehicular lamp are used as common parts, it is necessary to set the lamp mounting location in advance according to the required lamp. As a result, if the daytime running lamp becomes mandatory, the space problem is expected to become more prominent.

  The present invention has been made in view of the above problems, and the present invention provides a vehicular lamp capable of arranging various lamps including a daytime running lamp by effectively utilizing a limited lamp arrangement space. The issue is to provide.

In order to solve the above problems, the present invention has the following means.
That is, the present invention includes a headlamp provided with a first light source and a lens functioning as a headlamp inside, a surrounding reflection surface provided so as to cover the periphery of the lens surface of the headlamp, Extending along at least a part of the outer periphery of the reflecting surface, and the outer peripheral reflecting surface provided with the second light source on the inner surface thereof, and at least a part of the boundary between the outer peripheral reflecting surface and the surrounding reflecting surface A transmission part that transmits light from a second light source to the surrounding reflection surface, and the outer peripheral reflection surface and the surrounding reflection surface transmit light from the second light source in a predetermined optical axis direction. It is a vehicle lamp that reflects.

  In the present invention, for example, a lamp functioning as a daytime running lamp or a vehicle width lamp is arranged around a headlamp that has not been used effectively.

  Thereby, this invention can provide the vehicle lamp which can arrange | position the various lamps containing a daytime running lamp, utilizing the limited lamp arrangement space effectively.

  Further, according to the present invention, the ambient reflection surface around the headlamp is caused to emit light using the light of the light source on the outer periphery reflection surface.

  As a result, the present invention can efficiently provide a novel appearance that has never been achieved by using light that could not be used effectively.

  According to the vehicular lamp of the present invention, there is an excellent effect of providing a vehicular lamp capable of arranging various lamps including a daytime running lamp by effectively using a limited lamp arrangement space. obtain.

  The vehicular lamp 1 according to the present embodiment includes a headlamp 10 that forms a traveling beam or a passing beam, a daytime running lamp 20 that constantly emits light to ensure visibility from other vehicles, And an ambient light emitting unit 30 provided around the lens surface of the illumination lamp 10.

  The headlamp 10 uses a projector-type headlamp in the present embodiment. The headlamp 10 is a light source 11 such as an HID, a halogen bulb, or an LED, an elliptical reflecting surface 12 that reflects light from the light source 11 near the first focal point to a second focal point, and light from the elliptical reflecting surface 12. It has the lens 13 which consists of a convex lens to project. In the present invention, the headlamp is not limited to the projector type according to the present embodiment, but may be a reflective headlamp that irradiates with a reflecting surface of a paraboloid system with the vicinity of the light source as a focal point.

  The daytime running lamp 20 has a light source 22 on a reflecting surface 21 (corresponding to the outer peripheral reflecting surface of the present invention) arranged along at least a part of the surrounding light emitting unit 30 surrounding the lens surface of the lens 13 of the headlamp 10. , 23 are attached. The daytime running lamp 20 emits light directly from the light sources 22 and 23 and the reflected light from the reflecting surface 21 passes through the outer lens 24, so that a predetermined illumination direction of the lamp (front of the vehicle) ). Thereby, the daytime running lamp 20 can improve visibility from other vehicles.

  In this embodiment, the daytime running lamp 20 is disposed around the headlamp 10, but this portion can also be used as a vehicle width lamp.

  The ambient light emitting unit 30 is provided so as to surround the outer periphery of the lens 13 of the headlamp 10. The ambient light emitting unit 30 is a transmission surface 31 through which light from the light sources 22 and 23 passes between the daytime running lamp 20 and a reflection surface that reflects the light from the light sources 22 and 23 transmitted through the transmission unit 31 to the front of the vehicle. 32 (corresponding to the ambient reflection surface of the present invention) and an outer lens 33 covering the reflection surface 32.

  As described above, the transmission part 31 transmits the light sources 22 and 23 of the daytime running lamp 20 to the reflection surface 32 (see FIG. 2). For example, a transmission hole 31 or various light guide members are used. It may be filled.
