Description

  The present invention relates to a side marker unit that is mounted on the side of a large vehicle with a long vehicle length such as a truck or a bus. More specifically, the present invention relates to a side marker unit having a function of making it easier for a driver vehicle of the vehicle to recognize the vehicle body position of the vehicle width, or making a person other than the driver vehicle of the vehicle recognize the vehicle body.

  In a vehicle with a large inner ring difference, such as a bus or truck with a long car length, there may be an accident involving a passerby, a motorcycle, a bicycle, or the like that passes or runs alongside the vehicle. Also, especially at night when it is difficult to grasp the surrounding situation, an accident may occur in which a vehicle, a bicycle, a motorcycle, or another automobile collides with a vehicle stopped by the road. Therefore, in order to improve traffic safety, a self-luminous side marker unit (for example, see Patent Document 1) is conventionally attached to the side of the vehicle.

The side marker unit of the kind proposed by the above-mentioned patent document 1 employs an LED (light emitting diode) that consumes less power than a normal lamp as a light source, and the light of the LED is multi-faced cut. It passes through the applied dome-shaped cover and radiates around it.

  In the side marker proposed by Patent Document 1 (corresponding to a side marker unit), in order to increase the overall brightness of the cover obtained by the light of a plurality of LEDs, the LEDs are placed in the interior space of the cover. It is considered that measures are taken to change the position in the radial direction or axial direction of the cover. Depending on this, the light of the LED as the light source only radiates around the dome-shaped cover that has been cut in multiple faces. Therefore, even if a side marker unit is attached to the vehicle, it is easier for the driver in the driver's seat or outside the vehicle to recognize the width of the side marker unit or to notify the presence of a vehicle on the road. It can be said that it only demonstrates the function to perform.

  On the other hand, large vehicles such as buses and trucks with long car lengths inevitably have large inner wheel differences, but the road surface around the rear and rear wheels of the vehicle and its surroundings depend on the side mirror. There is a circumstance that it cannot be easily seen. In particular, such a situation appears remarkably when the surroundings are dark, such as at night.

  Therefore, the present invention does not separately equip the vehicle with an incandescent lamp that irradiates the road surface, but by utilizing the above-described side marker unit that has been used in the past, the road surface through which the rear and rear wheels of the vehicle pass.
