PROBLEM TO BE SOLVED: To prevent rotations of power source wiring which results from rotations of a light source unit in a lighting device where the light source unit is rotatably attached to a base.SOLUTION: A base 10 includes: a housing composed of a first half housing 110 and a second half housing 170 which may freely rotate on the first half housing; and an electric circuit member 160 housed in the housing. A light source unit is attached to the second half housing 170 of the base 10. The first half housing 110 includes an input port 119 for electrically connecting power source wiring 70 connected with an external power source with the electric circuit member 160. The second half housing 170 includes an output port 178 for electrically connecting the light source unit with the electric circuit member 160. |
