<P>PROBLEM TO BE SOLVED: To provide a variable lighting device advantageous to secure diversity of uses, due to possibility of readily changing lighting conditions during use. <P>SOLUTION: The variable lighting device includes a lighting unit irradiating light and equipped with a plurality of coupling end parts extended in a direction and at an angle different from each other, and a retention unit retaining the lighting unit by being selectively coupled with one of the plurality of coupling end parts of the lighting unit, and at the same time, impressing a power source in accordance with contact coupling device of with the lighting unit. According to state changes how the plurality of coupling end parts are coupled with the retention unit, at least either one out of an angle, a direction, a height, and a light volume is changed in which the lighting unit irradiates light. In such a structure, with an easy operation of changing coupling states between the lighting unit and the retention unit, lighting conditions can be readily changed, advantageous to secure diversity of uses. <P>COPYRIGHT: (C)2013,JPO&INPIT |
