[Prior art and its problems]

Conventionally, in lighting fixtures such as ceiling hanging lights that have two or more light source parts, each light source part is fixed in a fixed direction, so in such lighting fixtures, the direction of each light source part can be changed, It was not possible to illuminate various directions with each light source section.

In addition, desk lamps and the like have traditionally existed as lighting equipment whose light source can be changed in direction, but since desk lamps have one light source, it is not possible to illuminate various directions at the same time. I couldn't do it.

Furthermore, in conventional desk lamps, etc., a flexible pipe or a link mechanism was used in the stand part as a means to change the direction of the light source part, so it is possible to change the direction of two or more light source parts by such means. In this case, there were problems such as the lighting equipment itself becoming larger than necessary, and the driving part also becoming larger, making it very difficult to handle.

[Means for solving problems]

This idea was made to solve the above problems with conventional lighting equipment.
In a lighting fixture having two or more light source parts, each light source part can be easily and freely changed in various directions.

In the lighting device according to this invention, a mounting base 20 is provided on a holding part 10 such as a stand, and two or more rotating arms 30 are mounted on this mounting base 20 so as to rotate in the circumferential direction of the mounting base 20. At the same time, each rotating arm 30 is extended to the side of the mounting base 20.

Then, each rotating arm 3 extended in this way
