The support column 30 is a columnar member, and is, for example, a telephone pole provided with a power distribution line, a street light pole, or a pole for mounting a security camera. The support column 30 may have an L-shape or a T-shape. A plurality of support columns 30 are arranged along the edge of the road 90 at predetermined intervals, for example, at intervals of 20 m or more and 50 m or less, and a plurality of lamp bodies 20 are also arranged at the same predetermined intervals as described above.

FIG. 2 is a block diagram showing the functional configuration of the lighting system 1. FIG. 3 is a diagram of the lighting device 10 of the embodiment viewed diagonally from below.

As shown in FIG. 2, the lamp body 20 includes a light source 21, a communication section 22, a control section 25, and a sensor 26. Each of the light source 21, the communication section 22, and the sensor 26 is connected to the control section 25.

The communication unit 22 is a communication module that communicates with the server 50 via a network 40 such as the Internet. Communication between the communication unit 22 and the server 50 is realized by wired communication or wireless communication. The communication unit 22 is used, for example, to transmit vehicle information obtained by the sensor 26 via the network 40. Vehicle information will be described later.

As shown in FIG. 3, the lamp body 20 has a housing 29 that is a housing case. The light source 21, the communication unit 22, the control unit 25, and the sensor 26 are provided inside the housing 29 or on the outer surface of the housing 29. The housing 29 is fixed to the support column 30 by, for example, a ring-shaped member, a fastening member, or the like.

The housing 29 is provided at a position above the support column 30, for example, at a position of 4.5 m or more and 15 m or less from the road surface 91 of the road 90. The housing 29 has a rectangular parallelepiped shape, for example, and is provided on the support 30 so as to protrude from the support 30 toward the center of the road 90 . The housing 29 is made of a material such as metal or resin.

The light source 21 emits illumination light L1 onto the road 90 and the vehicle 80. The light source 21 is a liquid crystal projector that projects a still image or a moving image, or an LED (Light Emitting Diode) light emitting module that emits white light. When the light source 21 is a liquid crystal projector, the lighting device 10 can notify the vehicle 80 of parking-related information, which is information related to parking, using a still image or a moving image. Parking related information will be described later.

Sensor 26 is a detector that detects vehicle 80 on road 90. The sensor 26 is in constant operation to constantly detect the state of the predetermined area Z1 of the road 90. The predetermined area Z1 is, for example, an area including the shoulder of the road 90, and is set in advance corresponding to each lighting device 10. Although the predetermined area Z1 shown in FIG. 1 has a rectangular shape, the shape is not limited thereto and may be an ellipse or a semicircle.

As shown in FIG. 1, each sensor 26 is provided corresponding to each of the plurality of support columns 30 installed along the road 90.

Further, based on the image captured by the sensor 26, it is possible to detect whether or not there is a driver in the vehicle 80, and whether the vehicle 80 is parked on the shoulder of the road or in the travel lane.

When an infrared sensor is used as the sensor 26, the temperature of the vehicle 80 can be detected based on the difference in the frequency spectrum of reflected infrared waves. For example, if the temperature of the vehicle 80 is about the same as the outside temperature, it can be detected that the engine of the vehicle 80 is stopped.

When a laser sensor is used as the sensor 26, the distance can be measured from the arrival time of the reflected laser light, so the stopping time of the vehicle 80, the vehicle size, and the external shape of the vehicle 80 can be detected. Further, for example, by scanning a laser beam in a direction along the road 90, the position where the vehicle 80 is parked can be detected.

Each piece of information detected by the sensor 26 is output to the control unit 25.

The control unit 25 is a circuit that controls the light source 21 and the sensor 26. Further, the control unit 25 includes a clock circuit (not shown) for measuring the stopping time of the vehicle 80 and the like.
