Cables for electrically connecting the battery module 103 and the lamp body module 104 may be inserted through the connection part 801 and the second mounting part 602.

In some embodiments, in order to change the irradiation angle and the irradiation area of the lamp body module 104, the body portion 803 and the connection portion 801 are rotatably connected. After the connection portion 801 is connected and fixed to the lamp post 101, the body 803 is rotated with respect to the connection portion 801, so that the irradiation angle and the irradiation area of the lamp body module 104 can be changed. The rotational connection between the main body 803 and the connecting portion 801 may be achieved by hinges, and a rotational connection method that is convenient for adjusting the irradiation angle will be described below.

Referring to fig. 8 to 10, in some embodiments, the lamp body module 104 includes an adjusting member 802, the adjusting member 802 is connected to the main body portion 803, the connecting portion 801 has an adjusting groove 1002, the adjusting member 802 is slidably disposed in the adjusting groove 1002, and an end of the adjusting member 802 away from the main body portion 803 and the main body portion 803 can jointly clamp the connecting portion 801.
