In modern society, lighting devices such as street lights or security lights are installed in large areas such as downtowns, residential areas, roads, and parks. In the case of such a lighting device, since the installed number is significant, a lot of electrical energy is consumed. Therefore, in order to save electrical energy, it is important to turn on or off the street lights or security lights at an appropriate point in time depending on changes in the surrounding brightness.

In general, a method for controlling a street light may use a basic method of lighting a street light by sensing the amount of ambient light with a sensor or lighting a street light at a specified time by embedding a timer in the street light, and in addition, a control server for the street light It is also possible to install a wired/wireless communication module that can send and receive signals to and from the control server to remotely control the street light.
