[0001] The invention relates to the technical field of tower crane lamp devices, in particular to a solar tower crane lamp device. Background Art

[0002] Tower crane lamps are more and more used in construction sites, factories, mines, docks, airports, squares and other industries because of their safety, reliability, high brightness, energy saving and long life. Tower crane lamps are installed on the top of their respective places and can provide reliable lighting for construction sites, factories, mines, docks, airports, squares and other sites. At present, in the traditional process, a special lighting cable is led out from the temporary secondary box at the bottom of the tower crane to supply electricity for the tower crane lighting.
