Referring to Figure 2, the lighting device 20 may include a control module 21 for control of the overall operation. The control module 21 can control the power generation status of the first power generation module 23a such as a solar cell module and the second power generation module 23b such as a wind power generation module. For example, in the nighttime, the operation of the solar cell module 23a may be stopped and the power may be controlled to be generated mainly by the wind power generation module 23b. The generated power may be stored in the battery 24. The battery 24 may be composed of a plurality of cells and charge and discharge of each cell may be controlled. The battery management module 22 may be installed to control the first and second power generation modules 23a and 23b and the battery 24. The battery management module 22 may include a first power generation module 23a and a second power generation module 23a, The operation of the power generation module 23b may be controlled to control the charging status of the plurality of cells arranged in the battery 24. [ Then, the control module 21 of the battery management module 22 can transmit information on the power generation status and the battery status. The battery management module 22 may have a management database for managing charging and discharging of each cell of the first power generation modules 23a and 23b and the battery 24. [ The management database may, for example, have data such as the operating conditions of the first and second power generation modules 23a and 23b and the charging and discharging conditions of each cell of the battery 24.

The control module 21 can control the operation of the street lamp 11 in accordance with the information transmitted from the detection unit 26a and the monitoring unit 26b. When the vehicle detection signal is transmitted from the detection unit 26a, the control module 21 transmits it to the lighting control unit 25. [ The lighting control unit 25 detects the state of the battery 24 and turns on the street lamp 11 by using the cells determined to be in a discharged state under the control of the battery management module 22. [ Then, when the control module 21 receives a detection signal indicating that the vehicle has been passed by the detection unit 26a, the lighting control unit 25 turns off the street light 11. [ The lighting control unit 25 may be integrally formed with the control module 21 and may be directly connected to the battery management module 22. [ The lighting and the lighting of the street light 11 are determined by the vehicle detection signal of the detection unit 26a. As described above, a plurality of detection units 26a may be installed on both sides of the crosswalk. If the vehicle is detected on one side of the pedestrian crossing, the streetlight 11 is turned on. If the vehicle is detected on another detection unit 26a after several seconds or tens of seconds have elapsed, the streetlight should be turned off. The vehicle can pass on both sides and thus the vehicle passing on both sides can be detected by the respective detection unit 26a. In such a case, it is necessary to decide how to turn on and off the street light 11. First, at least one detection unit 26a installed on the other side of the crosswalk is synchronized and can detect, for example, vehicle speed. Depending on the vehicle speed, the time to be detected by the other detection unit 26a can be predetermined, and accordingly, the lighting and the lighting of the street lamp 11 can be determined. If a plurality of vehicles are detected simultaneously, the detection information for each vehicle can be transmitted to the control module 21 and accordingly the lighting control unit 25 can control the operation of the street lamp 11 according to a predetermined method have. In this manner, the lighting control unit 25 can have lighting management data. The lighting management data 25 can have data on the flashing condition of the street lamp 11 in accordance with the information transmitted by the detection unit 26a. The lighting control unit 25 can also have data according to lighting conditions of the streetlamp 11 according to the weather or the illuminance. Further, the lighting control unit 25 may have data on the illumination condition of the street lamp 11 depending on the condition of the battery 24. As such, the lighting control unit 25 may include various data related to the operating conditions of the streetlight 11 and is not limited to the illustrated embodiment.

The monitoring unit 26b can transmit the image information of the crosswalk to the control module 21. [ For example, if a person is passing through the crosswalk, the image information on the crosswalk can be transmitted to the control module 21. The control module 21 can convert the streetlight 11 into a flickering mode or generate warning signals of various types that can be transmitted to the driver according to the transmitted image information. On the other hand, the monitoring unit 26b can transfer the image information on the accident situation to the control module 21 and the control module 21 can store it in the memory 215. [ As described above, the memory 215 may be a replaceable memory and may be, for example, an SD memory card.

Various operating structures can be applied to the apparatus according to the present invention and the present invention is not limited to the embodiments shown.

The apparatus according to the present invention can be operated in conjunction with a traffic light.

Referring to FIG. The control module 21 may be connected to the traffic light SL and specifically to obtain operational information of the traffic light SL. As described above, the street lamp 11 can be activated when the vehicle is detected in the detection unit 26a, and on the other hand, when the walk signal is detected in the traffic light SL. The control module 21 may include, for example, a surveillance sensor unit 211 and a streetlight control unit 212. [ On the other hand, the monitoring unit 26b may be a closed circuit camera and the control module 21 may include an image reading unit for reading the image transferred from the monitoring unit 26b. For example, the image reading unit can generate a danger signal when the signal of the signal lamp SL is read from the image transferred from the signal in which the passage of the person is not allowed to the monitoring unit 26b.

Thus, the apparatus according to the present invention can be connected to the operation of the traffic light SL in various ways.
