  Therefore, in the vehicular lamp, a predetermined display is projected on the road surface by the light emission of the plurality of light emitting diodes.

  The vehicular lamp according to the present invention uses a plurality of light emitting diodes arranged on the outer periphery of the vehicle body and scattered as a light source, and projects a predetermined display functioning as a sign when it is lit on the road surface. It is characterized by that.

  Therefore, a sign can be specifically recognized by a pedestrian, a vehicle occupant, or the like by visually recognizing the display, and the sign function can be enhanced and safety can be improved.

  In the invention described in claim 2, since it is disposed on the side mirror, the side mirror is a portion protruding to the side, so that the display can be easily projected onto the road surface when the vehicular lamp is turned on. .

  The best mode for carrying out the vehicular lamp of the present invention will be described below with reference to the accompanying drawings.

  The vehicular lamp 1 is disposed on an outer peripheral portion of a vehicle body 101 of the vehicle 100, for example, a side mirror 102 (see FIG. 1).

  The vehicular lamp 1 includes a lamp housing 2 having a recess opened on one side and a transparent cover 3 that closes the opening surface of the lamp housing 2, and the lamp housing 2 and the cover 3 constitute a lamp outer casing 4. (See FIG. 2).

  A light source unit 5 is disposed inside the lamp outer casing 4. The light source unit 5 includes a circuit board 6 and a plurality of light emitting diodes 7, 7,... Mounted on the circuit board 6 and used as light sources.

  The light-emitting diodes 7, 7,... Are arranged at predetermined positions on the circuit board 6 in such a manner that a predetermined shape and image are displayed. The light emitting diodes 7,... Have emission colors such as blue, green, yellow, and white.

  In the vehicular lamp 1 configured as described above, the light is turned on when light is emitted from the light emitting diodes 7, 7,..., And the emitted light is transmitted through the lens 3 and displayed on the road surface 1000 with a predetermined display. 200 is projected. At this time, in the vehicular lamp 1 arranged on the right side mirror 102, the emitted light is projected on the right side of the vehicle 100 on the road surface 100 (see FIG. 1) and arranged on the left side mirror 102. In the vehicular lamp 1, the emitted light is projected onto the left side position of the vehicle 100 on the road surface 1000.

  The projected light is projected onto the road surface 1000 as a display 200 indicating “arrow”, for example. Therefore, when a pedestrian or a vehicle occupant visually recognizes the display 200 by the light emitted from the vehicle lamp 1, it recognizes that the vehicle 100 provided with the vehicle lamp 1 turns right.

  When the display 200 of the traveling direction of the vehicle 100 is performed, the lighting of the vehicle lamp 1 is performed simultaneously with blinking of the turn signal lamp, for example.

  Note that the visibility of the display 200 for a pedestrian or a vehicle occupant is higher at night than during the day.

  Although the example in which the vehicle lamp 1 is arranged on the side mirror 102 has been described above, the arrangement position of the vehicle lamp 1 is not limited to the side mirror 102, and may be any position as long as it is the outer peripheral portion of the vehicle body 101. Can be arranged.

  For example, the vehicular lamp 1 may be disposed on the flange 103 provided at the upper end of the rear end of the vehicle body 101 (see FIG. 3).

  When the vehicular lamp 1 is disposed on the collar portion 103, when the vehicular lamp 1 is turned on, light is projected as a predetermined display 200 at a position on the road surface 1000 on the rear side of the vehicle 100. The projected display 200 is, for example, “STOP”, “stop”, “BACK”, “back”, etc. In the case of “STOP”, “stop”, a pedestrian or a passenger of the vehicle By visually recognizing the display 200 by the light emitted from the lamp 1, it is recognized that the vehicle 100 stops traveling. In the case of “BACK”, “back”, etc., a pedestrian or a passenger of the vehicle By recognizing the display 200 by the light emitted from the vehicle lamp 1, it is recognized that the vehicle 100 moves backward.

  When the display 200 is displayed such that the vehicle 100 stops traveling due to the lighting of the vehicle lamp 1, for example, the lighting of the vehicle lamp 1 is performed simultaneously with the lighting of the stop lamp. When the display 200 is performed such that 100 moves backward, the vehicular lamp 1 is turned on simultaneously with the backup lamp.

  The above-mentioned “arrow”, “STOP”, “stop”, “BACK”, and “back” at the time of lighting of the vehicle lamp 1 are examples of the display 200, respectively. The display 200 can be configured to be performed. For example, when the vehicle lamp 1 is lit, a display 200 that images various shapes such as various marks, various characters, people, animals, buildings, and the like may be projected on the road surface 1000 as a sign. Further, for example, it is possible to project a display 200 indicating the vehicle width on the road surface 1000 when the vehicle 100 is traveling, so as to prevent the wheel from coming off or contact with another vehicle or the like.

  As described above, since the vehicle lamp 1 projects the predetermined display 200 that functions as a sign on the road surface 1000, a pedestrian, a vehicle occupant, etc. can visually recognize the display 200. Thus, the sign can be specifically recognized, the sign function is enhanced, and the safety can be improved.

  Further, since the vehicle lamp 1 is disposed on the side mirror 102, the side mirror 102 is a portion protruding sideways, so that the display 200 can be easily projected onto the road surface 1000 when the vehicle lamp 1 is turned on. it can.
