  The lighting fixture according to the present embodiment is similar to the conventional lighting fixture shown in FIG. 5, and has a substantially rectangular fixture main body 10 to which an illumination lamp 11 such as a fluorescent lamp is attached as a light source, and a lower portion of the fixture main body 10. The sensor attachment part 20 and the sensor block 30 attached to the side are provided. Moreover, this lighting fixture is provided with the dummy block 40 shown in FIG. 2, and attaches and uses either the sensor block 30 or the dummy block 40 to the sensor attachment part 20 according to the intended purpose.

  As shown in FIG. 3, the fixture body 10 includes a lighting circuit 12 that supplies lighting power for the illumination lamp 11, and switching the lighting lamp 11 on and off via the lighting circuit 12, and adjustment of the dimming level. And a control unit 13 that performs lighting control. The control unit 13 performs lighting control of the illumination lamp 11 based on an operation signal from the remote control receiving unit 21 described later and sensor signals from the human sensor 31 and the brightness sensor 32.

  As shown in FIG. 1A, the sensor mounting portion 20 is formed in a substantially cubic shape having a long side in the left-right direction, and a prism-shaped protruding portion 23 in which the vicinity of the right end of the lower side surface protrudes downward. Is provided. A remote control receiver 21 for receiving an operation signal from the remote controller transmitter 50 is installed on the lower surface of the protrusion 23.

  In addition, the sensor mounting portion 20 supplies operating power to the sensor block 30 and includes a conduction portion 22 on the lower side surface for receiving a sensor signal input from the sensor block 30. The sensor signal input from the sensor block 30 is input to the lighting circuit via the conduction unit 22, and the lighting lamp 11 is switched on / off and the dimming level is adjusted based on the input sensor signal. .

  Further, claw portions 34a and 34b of the sensor block 30, which will be described later, are respectively inserted into the lower side surface of the sensor mounting portion 20, and locking holes 24a and 24b for holding the sensor block 30 are formed at substantially the center in the left-right direction. Is provided. Each of the locking holes 24 a and 24 b is a rectangular hole having a long side in the left-right direction of the sensor mounting portion 20, and is installed at a position slightly inside from the end in the front-rear direction of the sensor block 30.

  As shown in FIG. 1B, the sensor block 30 is formed to be approximately the same size as the sensor mounting portion 20, and a human sensor 31 and a brightness sensor 32 are provided on the lower side surface thereof. ing. In each sensor 31, 32, in a state where the sensor block 30 is attached to the sensor attachment portion 20, a detection area is set in the illumination area and its surroundings. In addition, a conductive portion 33 that is electrically connected to the conductive portion 22 is provided at a position facing the conductive portion 22 on the upper side surface of the sensor block 30. As a result, each of the sensors 31 and 32 receives the operating power via the conduction parts 22 and 33, detects the movement of the person and the surrounding brightness, and outputs a sensor signal to the lighting circuit of the sensor mounting part 20. .

  Further, the upper side of the sensor block 30 is opened to the upper side of the sensor block 30, and the protruding portion 23 of the sensor mounting portion 20 is inserted through the opening, and the holding is set to be approximately the same size as the outer periphery of the protruding portion 23. A hole 37 is provided. The inner wall of the holding hole 37 functions as a guide for inserting the protruding portion 23 when the sensor block 30 is attached to the sensor attachment portion 20. Further, when the protruding portion 23 is inserted into the holding hole 37 and the sensor block 30 is attached to the sensor mounting portion 20, the inner wall of the holding hole 37 comes into contact with the side wall of the protruding portion 23 and the sensor block 30 moves in the front-rear direction. To regulate. Thereby, by attaching the sensor block 30 to the sensor attachment part 20, the detection range of each sensor 31 and 32 is reliably set to the preset range.

The sensor block 30 is pushed up. As a result, the locking portion 35 of the claw portion 34 hits the locking hole 24, the claw portion 34 is pushed inward and bent, and the entire claw portion 34 is inserted into the locking hole 24. When the entire claw part 34 is inserted into the locking hole 24, the force applied by the locking part 35 hitting the locking hole 24 is lost, and the claw part 34 is locked by the return force of the claw part 34. The part 35 moves slightly outward. Accordingly, the locking portion 35 is locked by the inner wall around the locking hole 24, and the sensor block 30 is held by the sensor mounting portion 20.

  Thus, when attaching the sensor block 30 to the sensor attachment part 20, since the protrusion part 23 is inserted in the holding hole 37, attachment direction is not mistakenly attached. Further, the movement of the sensor block 30 in the front-rear and left-right directions is restricted by the inner wall of the holding hole 37 and the protrusion 23, and the detection range of the sensors 31, 32 can be reduced from being set to an unintended range. Moreover, since the protrusion part 23 is covered with the sensor block 30, and the boundary line of the sensor block 30 and the sensor attachment part 20 does not appear on the surface, it can suppress that the designability falls.

  Further, when the sensor block 30 is removed from the sensor mounting portion 20, when the periphery of each claw portion 34 is pushed inward, the claw portion 34 is bent inward to release the locking by the locking portion 35. Can be removed by pulling down. At this time, since the slits 36 are provided on the left and right sides of the claw portion 34, the force for pushing the claw portion 34 from the outside is small, and the sensor block 30 can be easily detached from the sensor mounting portion 20.

  The dummy block 40 is formed in substantially the same shape as the sensor block 30. The dummy block 40 is fitted with the holding holes 41 for inserting and holding the protruding portions 21 and the locking holes 24a and 24b so that the dummy block 40 is attached to the sensor mounting portion. 20 has claw portions 42a and 42b for holding the same. Slits 43, 43 are provided on the left and right of the claw portions 42a, 42b, respectively, so that the dummy block 40 can be easily detached from the sensor mounting portion 20.

  Thereby, when using the lighting fixture concerning this Embodiment as a normal lighting fixture which does not use a sensor, it prevents that the designability falls by attaching the dummy block 40 instead of the sensor block 30. FIG. Can do.

  As shown in FIG. 3, the locking holes 24a, 24b of the sensor mounting portion 20 are set to have different lengths in the left-right direction, and the claw portions 34a, 34b are respectively set to the corresponding locking holes 24a. , 24b may be formed to match the length. The locking hole 24a is shorter than the locking hole 24b, and is set to a width that prevents the claw portion 34b from being inserted into the locking hole 34a. By doing in this way, it can further prevent that the attachment direction of the sensor block 30 is attached accidentally.

  Further, as shown in FIG. 4, a locking hole 24 c having a long side in the front-rear direction of the sensor mounting portion 20 is provided, and the sensor block 30 is substantially the same as the claw portions 34 a and 34 b at a position corresponding to the locking hole 24 c. You may make it provide the nail | claw part 34c of the same shape. This prevents the sensor block 30 from being attached in the wrong direction, and increases the attachment strength when the sensor block 30 is attached to the sensor attachment portion 20, so that the sensor block 30 is attached to the sensor attachment portion 20. Can be prevented from falling off.
