In addition, this operation method can control the lighting operation mode according to the detected fog concentration (S204). Such lighting operation mode control may be performed before, after, or simultaneously with lighting brightness adjustment.

Referring to FIG. 21 , in the method of operating the road lighting system according to the present embodiment, the controller receives a fog-related control signal from a network through a communication unit (S211), and operates the lighting of the lighting lamp based on the fog-related control signal It may include a series of steps of setting the timing (S212) and controlling the dimming of the lighting of the lighting lamp according to the set operation timing (S213).

In addition, according to the operating methods of the road lighting system according to the above-described embodiments, the control unit receives the fog-related control signal from the network through the communication unit, and sets the operation timing for the lighting of the lighting lamp based on the fog-related control signal And it is possible to control the dimming of the lighting according to the operation timing. In addition, before, after, or simultaneously with this series of processes, the controller may determine the fog concentration based on the sensor signal from the sensor, and adjust the brightness of the lighting lamp according to the fog concentration.

Here, the protection wall includes a lighting lamp receiving groove for inserting a lighting lamp inside the outer wall, and a light guide groove extending from the lighting lamp seating groove and having a predetermined depth and guiding the light beam of the lighting lamp inserted into the lighting lamp seating groove to the lower side of the protection wall, The light guide groove has a shape in which the width of the groove is widened from the light mounting groove to the lower side of the protection wall.

According to the above-described configuration, it is possible to provide a solar cell module and a lighting lamp (or fog lamp) integrated PC protection wall (concrete protection wall) that can effectively secure the visibility of road lighting even in bad weather at night. In other words, in improving the visibility in front of the driver to promote driving safety, unlike the existing line lighting, it is possible to provide a safe and comfortable road driving environment by securing optimal visibility performance or forward visibility even at night and in bad weather (fog).

In addition, according to the above-described embodiment, while complying with the standards or specifications of concrete firewalls (PC firewalls), the electrical stability of the lighting integrally installed on the firewall is secured and the road lighting performance is maximized through a structure that effectively uses the optical performance, and broadband It is possible to provide a road lighting system with a new structure equipped with an energy-independent power supply system by using a solar cell module that is configured to be dimming controllable through a network including wireless communication and verified charge/discharge efficiency and long-term operation stability. .
