Lighting device
The lighting device includes a rod and two or more lighting units superimposing each other. Each of the lighting units includes a housing and a lighting element. The housing has a through hole, a first conductive element, a second conductive element and a positioning mechanism. The through hole is penetrated by the rod so that the housing can turn about the rod. The positioning mechanism limits the lighting units to turn between a first position and a second position. The first conductive elements and second conductive elements of the lighting units make contact at the second position, respectively.
