2. Description of the Related Art For example, when a vehicle is parked in a parking lot,
In the daytime, the parking position can be easily confirmed by eye, so that the vehicle does not often collide with a car stop or run off the line indicating the parking area of each vehicle.

[0003]

However, since the parking position cannot be seen very well at night, an accident such as a collision with a car stop or a collision with an adjacent vehicle may occur. In addition, since the line indicating the parking area is not clearly seen, the parking area may protrude from the parking area, so that the vehicle is straddled over the adjacent parking area and cannot be fully parked up to the predetermined parking capacity. Cases occur frequently.

Therefore, conventionally, the parking position is made easy to understand by illuminating with a street light or the like. However, a large number of lighting fixtures are required, and the power consumption is not increased accordingly.

Absent. That is, for example, discharge lamps such as metal halide lamps, mercury lamps, sodium lamps, xenon lamps, electrodeless discharge tubes, halogen lamps, incandescent lamps, LE
D, a laser, a fluorescent lamp, and the like are exemplified. However, an LED is preferable because it is hard to cause electric leakage and failure due to power consumption and rainwater and is compact.

The driving device 3 is for supplying power to the light source. In this embodiment, a solar cell is used. In addition, for example, a LED is supplied from a power supply such as a battery or a DC / AC power supply. An electric circuit (a resistor, a transistor, a constant current diode, or the like) for generating a direct current for lighting is provided, and is operated by power supply from a battery or the like in rainy weather. The driving device itself may be separately provided without attaching a solar cell or a secondary power supply (battery). Further, a portion of the drive device 3 from which the wiring cord 30 is led out is provided with an appropriate sealing material so as to be sufficiently waterproof.

Therefore, according to this embodiment, since a solar cell is used, it is not necessary to use a battery or a DC / AC power supply in fine weather, so that power consumption can be minimized.
