<P>PROBLEM TO BE SOLVED: To provide a lighting unit capable of making a case for storing a light source rotate in a range of 360° around a rotary axis consistent with its gravity position and facilitating an adjusting work of an irradiating range of light. <P>SOLUTION: A lighting unit 110 including the case 10 for internally storing the light source is rotatably supported by support members 20 arranged on both ends. A plurality of mounting holes 23 are formed on the whole periphery of an annular section 22 of the support member 20 centering on the gravity position of the lighting unit 110. Arc sections 15 in sliding contact with an inner peripheral surface 22A of the annular section 22 are formed at both ends of the case 10. The lighting unit 110 is rotatably supported at an angle range of 360° around a gravity axis along the inner peripheral surface of the annular section 22. When fixing screws 19 are fastened to screw holes 18 of the case 10 through either of mounting holes 23, the lighting unit 110 can be fixed to the support member 20 at an arbitrary rotary position. <P>COPYRIGHT: (C)2012,JPO&INPIT |
