<p><P>PROBLEM TO BE SOLVED: To provide a luminaire the cost reduction of which is achieved with respect to a sensor switch by miniaturizing the sensor switch and standardizing parts of the sensor switches. <P>SOLUTION: A detecting means 30 mounted on a luminaire body 20 detects a lighting environment, and a light output of a lamp 21 is adjusted based on the detection results. In this case, a rotary switch 32 is used as a sensor switch for adjusting the detecting means 30, so that the miniaturization can be achieved in comparison to a conventional sliding type switch. Furthermore, a projection 323 is formed on a rotary shaft 322 of the rotary switch 32, and a rotation restriction member 324 for restricting a rotation angle of the rotary shaft 322 by being attached to the projection 323 of the rotary shaft 322 is formed on the inner surface of a cover 314 covering the rotary switch 32, thereby the same rotary switch 32 can be used even when the adjusting ranges of the detecting means 30 are different from each other. Accordingly, the cost reduction of the sensor switch can be achieved and thus the cost reduction of a luminaire 10 can be achieved. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
