  The infrared sensor 260 is well known in the art, and is configured to detect the movement (presence) of a person in a detection region by detecting infrared rays emitted from a human body with a pyroelectric element. The signal processing circuit outputs a human body detection signal when the infrared sensor 260 detects the presence of a person. However, the sensor is not limited to the passive infrared sensor 260 using a pyroelectric element, and may be an sensor using an image sensor or an active sensor using radio waves or ultrasonic waves.

  The signal processing circuit continues to output the human body detection signal until a predetermined operation holding time elapses after the infrared sensor 260 no longer detects the presence of a person. The signal processing circuit also stops the output of the human body detection signal if the infrared sensor 260 does not detect the presence of a person before the operation holding time elapses, and the infrared sensor 260 is turned on again before the operation holding time elapses. When the presence of a person is detected, the human body detection signal is continuously output. The variable resistor 261 is provided for adjusting the operation holding time. That is, the signal processing circuit is configured to adjust the operation holding time corresponding to the resistance value of the variable resistor 261. However, a rotary switch may be used instead of the variable resistor. Although not shown, a power supply line for supplying power to the human body detection unit 26 and an output line for outputting a human body detection signal from the signal processing circuit are drawn out from the printed wiring board 262.

  Further, the human body detection unit 26 is held by the holding member 27 as shown in FIGS. The holding member 27 is made of a rectangular box-shaped synthetic resin molded body having an opening on one side, and is configured to house and hold the human body detection unit 26 therein. On the outer peripheral surface of the holding member 27, a step portion 270 is formed over the entire periphery. Furthermore, the first wall hole 2710 through which the lens 2600 of the infrared sensor 260 is inserted and the second window hole 2711 through which the operation knob 2610 of the variable resistor 261 is inserted penetrate the bottom wall 271 of the holding member 27. ing.

  The holding member 27 is formed in a semi-cylindrical surface shape in which a side wall 272 facing the short side direction (left and right direction) among the side walls from the step portion 270 to the bottom wall 271 is convex inward. In addition, a pair of first hook portions 273 and a pair of second hook portions 274 protrude from both ends in the front-rear direction on the left and right side surfaces in the vicinity of the opening end of the holding member 27. The first hook portion 273 is formed in a bowl shape (S-shape) when viewed from the front-rear direction. The second hooking portion 274 is formed in an L shape when viewed from the up and down direction.

  The holding member 27 is attached to the attachment member 21 via the base 28. In the pedestal 28, a rectangular plate-shaped main portion 280 and a pair of rectangular tube-shaped protrusions 281 protruding upward from the left and right sides of the main portion 280 are integrally formed as a synthetic resin molded body. In addition, rectangular insertion grooves 282 are provided at both left and right ends on the rear end side of the main portion 280, respectively. Further, on the left and right sides of the front end side of the main portion 280, hook-shaped protrusions 283 are provided so as to protrude downward.

  As shown in FIG. 3, the pedestal 28 is attached to the attachment member 21 by fitting a pair of projections 281 into a pair of through holes 2110 provided in the bottom plate 211 of the attachment member 21. The plurality of LEDs 222 mounted near the end of the LED module 22 are hidden by a pedestal 28 attached to the attachment member 21.

  The holding member 27 is slid in parallel with the main portion 280, thereby inserting the pair of first hook portions 273 into the pair of insertion grooves 282, and the pair of second hook portions 274 into the pair of projecting pieces 283. Each is hooked and attached to the base 28 (see FIG. 4). That is, the holding member 27 is attached to the pedestal 28 so as to be movable along the longitudinal direction (front-rear direction) of the attachment member 21.

  Next, the assembly procedure of the light source unit 2 will be described. First, the operator attaches the power supply device 24 to the upper surface side of the bottom plate 211 of the attachment member 21, and fixes the LED module 22 to the bottom plate 211 of the attachment member 21 with the locking claws 2111. Thereafter, the operator passes an electric wire led out from the connector 223 of the LED module 22 through a hole provided in the bottom plate 211 of the mounting member 21, and connects an end thereof to the power supply device 24.

  Subsequently, the worker stores and holds the human body detection unit 26 inside the holding member 27. At this time, the operator draws the power supply line and the output line drawn out from the human body detection unit 26 out of the holding member 27 through the insertion groove 276 provided near the opening end of the holding member 27.

  Next, the operator inserts the pair of first hook portions 273 into the pair of insertion grooves 282 and hooks the pair of second hook portions 274 on the pair of projecting pieces 283, respectively, so that the holder 27 Install 28.

  Further, the operator attaches the front end portion of the holding member 27 (the portion from the step portion 270 to the bottom wall 271; hereinafter the same) to the hole 2900 of the curved surface portion 290 of the second cover body 29 and the back surface of the curved surface portion 290. The step portion 270 of the holding member 27 is abutted against the wall 2901 of the curved surface portion 290 through the side (upper side). As a result, the distal end portion of the holding member 27 protrudes out of the second cover body 29 through the hole 2900. At this time, the holding member 27 is configured such that the side wall 272 of the holding member 27 and the curved surface portion 290 of the second cover body 29 are flush with each other. Therefore, the joint between the holding member 27 and the second cover body 29 becomes inconspicuous, and the appearance can be improved.

  Subsequently, the worker attaches the second cover body 29 to which the holding member 27 and the base 28 are attached to the first cover body 23A. At this time, the protruding piece 292 of the second cover body 29 is fitted inside the end portion of the first cover body 23A (end portion of the curved surface portion 231), whereby the curved surface portion 290 of the second cover body 29 and the first The curved surface portion 231 of the cover body 23A is flush. In addition, the second cover body 29 is fixed to the first cover body 23A by fitting the protruding wall portions 233 of the first cover body 23A into the pair of slits 295 of the second cover body 29 (FIG. 1). reference). The two cover bodies 23A and 29 are preferably bonded with an adhesive.

  Then, the operator attaches the cover 23 (the first cover body 23A and the second cover body 29) to the attachment member 21 with the opening side facing upward. At this time, the protrusions 233A provided on the respective protruding wall portions 233 of the first cover body 23A are hooked on the inclined portions 212A provided on the side plates 212 of the attachment member 21, respectively, and the first cover body 23A is attached to the attachment member 21. It is attached. Further, the operator draws the power supply line and the output line drawn out from the insertion groove 276 to the upper surface side of the mounting member 21 through the inside of one protrusion 281 and connects to the power supply device 24.

  Finally, the operator inserts a stepped screw 235 into a long hole-like through hole (not shown) provided in the protruding wall 293 of the second cover body 29, and the screw provided in the side plate 212 of the mounting member 21. The cover 23 is screwed to the mounting member 21 by screwing the threaded portion of the stepped screw 235 into the hole 2120. The light source unit 2 is assembled according to the above procedure.

  Then, the construction procedure of the lighting fixture A is demonstrated. First, the operator passes the power line 3 (see FIG. 1) wired in advance on the back of the ceiling through the hole 111A of the instrument body 1, and further passes the suspension bolt 200 exposed indoors through the hole 111B. The nut body 300 is screwed into the suspension bolt 200 to fix the instrument body 1. Thereafter, the operator connects the end of the power supply line 3 to the terminal block 13, and further connects the female connector 131 of the terminal block 13 and the male connector 243 of the power supply device 24.

  Finally, the operator hooks the tips of the hooks 214 into the pair of insertion holes 112A provided on one side plate 112 of the instrument body 1, and then attaches the pair of hook springs 215 to the other side plate of the instrument body 1. Hook on a hook 1120 provided on 112. Then, when the operator rotates the light source unit 2 with the hook metal 214 as a fulcrum, the hook spring 215 is returned to the original state while being hooked on the hook portion 1120, so that the light source is driven by the spring force of the hook spring 215. The unit 2 is held by the instrument body 1. The lighting fixture A is constructed on the ceiling according to the above procedure.

  Thus, in the lighting fixture A of the present embodiment, for example, while the human body detection signal is output from the human body detection unit 26, the power supply 24 supplies the rated power to the LED module 22 and causes the LED 222 to be rated. On the other hand, when the human body detection signal is not input from the human body detection unit 26 and the standby time elapses, the power supply device 24 stops the power supply to the LED module 22 or reduces the output power to turn off the LED 222 or dimm it. That is, by using the light source unit 2 of the present embodiment, it is possible to achieve energy saving by blinking (or switching between rated lighting and dimming lighting) according to the presence or absence of a person.

  As described above, the light source unit 2 of the present embodiment is detachably attached to the fixture body 1 of the lighting fixture A, supporting the light source (LED module 22) having one or more solid light emitting elements (LEDs 222). The mounting member 21 is provided. In addition, the light source unit 2 of the present embodiment includes a cover 23 that is at least partially formed into a box shape with a light-transmitting material and is attached to the attachment member 21 so as to cover the light source. Further, the light source unit 2 of the present embodiment includes a power supply device 24 that is attached to the attachment member 21 and supplies power to the light source, and a functional component that acts on the power supply device 24 to realize functions related to the light source (human body detection unit 26 ). The functional component is disposed on the cover 23 in a state where at least a part (lens 2600) is exposed outside the cover 23 from the hole 2900 provided in the cover 23 (second cover body 29).

  Since the light source unit 2 of this embodiment becomes the lighting fixture A to which the desired function was added by replacing with the light source unit 2 which mounted the desired functional component, compared with the case where a functional component is provided in the instrument main body 1. The introduction cost can be reduced. Moreover, since the lens 2600 of the infrared sensor 260 is exposed to the outside of the cover 23 through the hole 2900 provided in the second cover body 29, the human body detection unit 26 can be connected to the cover 23 without greatly changing the shape of the cover 23. It can be stored in a space formed by the mounting member 21. Further, the light source unit 2 of the present embodiment is basically a type in which no functional parts are mounted (basic) except that the cover 23 is composed of two members (a first cover body 23A and a second cover body 29). Type) light source unit. Therefore, the light source unit 2 of the present embodiment can be manufactured with only a simple specification change by changing the cover from the basic type light source unit and incorporating a functional component, and the manufacturing cost from the basic type light source unit. Can be suppressed as much as possible.

  Further, the light source unit 2 of the present embodiment includes a holding member 27 that holds the functional component (human body detection unit 26) and protrudes out of the cover 23 from the hole 2900. In addition, the holding member 27 has a stepped portion 270 that is caught on the periphery of the hole 2900. As described above, since the functional component (human body detection unit 26) is held by the holding member 27, it is possible to easily cope with the change of the functional component. Further, since the holding member 27 and the second cover body 29 are coupled so that the step portion 270 is hooked on the peripheral edge of the hole 2900, the holding member 27 can be reliably positioned and fixed with respect to the cover 23. .

  By the way, since the cover 23 of the light source unit 2 of the present embodiment is made of a synthetic resin material, the cover 23 is expanded by the influence of heat generated by the LED module 22 and the power supply device 24 during lighting, and contracts after being extinguished. The dimensions (particularly the length in the longitudinal direction) are likely to vary. Therefore, in this embodiment, when the cover 23 is screwed to the mounting member 21, the screw is a stepped screw 235, and a hole (through hole of the cover 23) through which the stepped screw 235 passes is formed in a long hole shape. ing. Therefore, even if the cover 23 expands and contracts, unnecessary stress is hardly applied to the cover 23 from the stepped screw 235. Further, in the present embodiment, the holding member 27 is configured to be movable along the longitudinal direction of the mounting member 21 with respect to the base 28 fixed to the mounting member 21. Therefore, since the holding member 27 and the second cover body 29 move in conjunction with the expansion and contraction of the cover 23, it is difficult to apply unnecessary stress to the holding member 27 and the second cover body 29 as well. As a result, it is possible to suppress problems such as breakage of the cover 23 and occurrence of abnormal noise.

  As described above, the light source unit 2 of the present embodiment includes the pedestal 28 fixed to the attachment member 21. The holding member 27 is configured to be attached to the base 28.

  Since the light source unit 2 of the present embodiment is configured as described above, the pedestal 28 can be used in common by preparing the holding member 27 according to the type of the functional component, thereby reducing the manufacturing cost. Can do.

  Further, in the light source unit 2 of the present embodiment, the pedestal 28 has one or more hooks on which one or more hooks (the first hook 273 and the second hook 274) provided on the holding member 27 are hooked. Parts (insertion grooves 282 and protrusions 283). The holding member 27 is slid along the attachment member 21 so that the hooking portions (the first hooking portion 273 and the second hooking portion 274) are hooked on the hooked portions (the insertion groove 282 and the protruding piece 283). Configured.

  Since the light source unit 2 of the present embodiment is configured as described above, the workability of the assembly work can be improved by not using screws or the like.

  Further, in the light source unit 2 of the present embodiment, the base 28 is covered with the hooking portions (the first hooking portion 273 and the second hooking portion 274) being hooked on the hooked portions (the insertion groove 282 and the protruding piece 283). The holding member 27 is movably supported along the longitudinal direction of 23.

  Since the light source unit 2 of the present embodiment is configured as described above, the holding member 27 and the cover 23 (second cover body 29) move in conjunction with the expansion and contraction of the cover 23, and the holding member 27 And it becomes difficult to apply unnecessary stress to the cover 23. As a result, the light source unit 2 of the present embodiment can suppress the occurrence of problems such as cracking of the cover 23 and occurrence of abnormal noise.

  By the way, when the functional component (human body detection unit 26) is arranged on the upper surface side of the mounting member 21, it is difficult to expose the lens 2600 of the infrared sensor 260 outside the light source unit 2 while avoiding the influence of the light of the LED 222. is there.

  On the other hand, in the light source unit 2 of the present embodiment, the functional component (human body detection unit 26) has at least a part exposed outside the cover 23 from the hole 2900 provided in the cover 23 (second cover body 29). In the state, it is arranged in a space surrounded by the cover 23 and the mounting member 21. Therefore, it becomes easy to expose the lens 2600 of the infrared sensor 260 to the outside of the light source unit 2 while avoiding the influence of the light of the LED 222.

  Further, when a part of the functional component (for example, the lens 2600 of the infrared sensor 260) is exposed outside the cover 23, a structure in which a hole is formed in the curved surface portion 231 of the cover 23 (first cover body 23A) is conceivable. However, when making a hole in the cover 23, it is necessary to shield the periphery of the hole so that the shadow of the functional component is not noticeable.

  On the other hand, in the light source unit 2 of the present embodiment, the cover 23 is formed of one or more first cover bodies 23A formed of a material having translucency, and a material having no translucency, and And a second cover body 29 provided with a hole 2900. The first cover body 23A and the second cover body 29 are attached to the attachment member 21 so that the ends of the first cover body 23A and the second cover body 29 abut each other. That is, since the cover 23 is composed of a plurality of parts including a first cover body 23A and a second cover body 29, and the second cover body 29 is formed of a material having no translucency, a light source (LED module 22) Since the second light is blocked by the second cover body 29, there is an advantage that the shadow of the functional component is not noticeable.

  Further, when the cover 23 is composed of a plurality of parts, the end portions of the two cover bodies 23A and 29 can be easily formed by simply abutting the end portion of the first cover body 23A and the end portion of the second cover body 29. There is a possibility that the joints are easily noticeable.

  On the other hand, the light source unit 2 of the present embodiment has a fitting structure in which the protruding piece 292 protruding from the end portion of the second cover body 29 is fitted inside the end portion of the first cover body 23A. For this reason, there is an advantage that the ends of the two cover bodies 23A and 29 are not easily displaced, and as a result, the joint between the ends is less noticeable. Instead of providing the protruding piece 292 at the end of the second cover body 29, a protruding piece is provided at the end of the first cover body 23A, and the protruding piece is fitted inside the end of the second cover body 29. The light source unit 2 may have a structure.

  Further, as shown in FIG. 5, the cover 23 is composed of two first cover bodies 23A and 23B and one second cover body 29, and the second cover body 29, that is, a functional component ( A human body detection unit 26) may be arranged. However, since the power supply device 24 is disposed near the center of the mounting member 21, in order to suppress the influence of the heat generated by the power supply device 24, the functional component (human body detection unit 26) is provided as in this embodiment. It is preferable to arrange at the end in the longitudinal direction.

  Instead of the human body detection unit 26, a brightness detection unit may be mounted on the light source unit 2 as a functional component. The brightness detection unit is configured by mounting a brightness sensor on a printed wiring board 262 instead of the infrared sensor 260. The brightness sensor detects (measures) the brightness (illuminance) of the illumination space using a photoelectric conversion element such as a solar cell. The signal processing circuit is configured to compare the measurement value of the brightness sensor with a predetermined threshold value and output a brightness detection signal when the measurement value falls below the threshold value. For example, the power supply 24 turns on the LED 222 by supplying power when the brightness detection signal is output, and turns off the LED 222 by stopping power supply or reducing the output power when the brightness detection signal is not output. Or it is comprised so that light control lighting may be carried out. In addition to the human body detection unit 26 and the brightness detection unit, for example, a drawstring type switch (so-called pull switch) may be mounted on the light source unit 2 as a functional component.

(Embodiment 2)
Another embodiment of the light source unit 2 according to the present invention will be described. However, the light source unit 2 of the present embodiment is characterized by a configuration for attaching the functional component to the mounting member 21, and the other configurations are the same as those of the first embodiment. Therefore, the same components as those in the first embodiment are denoted by the same reference numerals, and illustration and description thereof are omitted as appropriate.

  Hereinafter, for simplicity of explanation, a block including a functional component and a member for attaching the functional component to the attachment member 21 will be referred to as a functional block.

  As shown in FIG. 6, the functional block in this embodiment includes a human body detection unit 26, a holding member 27, a base 28, a second cover body 29, and a support frame 25. In the following description, unless otherwise specified, the vertical, horizontal, and front-rear directions are defined in FIG.

  The holding member 27 includes four rectangular flat plate-like hook portions 275 instead of the first hook portion 273 and the second hook portion 274. These four hook portions 275 are configured to protrude in the left-right direction from the front end and the rear end at the upper ends of the left and right side surfaces of the holding member 27, respectively.

  On the other hand, the base 28 is provided with four hooked portions 284 in place of the insertion groove 282 and the projecting piece 283. These hooked portions 284 protrude downward from the front end and the rear end at the left and right ends of the lower surface of the main portion 280, respectively. The left hooked portion 284 is formed in a half-square cylinder shape that is opened rearward and rightward. Also, the right hooked portion 284 is formed in a half-square cylinder shape that is opened rearward and leftward. A space 2840 into which the hooking portion 275 of the holding member 27 can be inserted is formed inside each hooked portion 284 (see FIG. 7). That is, each hooking portion 275 of the holding member 27 is hooked on the hooked portion 284 of the base 28 by being inserted into each space 2840 from the rear end toward the front (see FIG. 8). However, each space 2840 is formed such that the length in the front-rear direction is longer than the width in the front-rear direction of the hook portion 275. Therefore, the holding member 27 can move in the front-rear direction with respect to the base 28 in a state where the hooking portion 275 is hooked on the hooked portion 284. Note that a minute protrusion 285 is provided on the lower surface of the main portion 280 of the base 28 on the path through which the hook portion 275 on the right front side passes (see FIG. 6). In other words, since the hooking portion 275 does not detach from the hooked portion 284 unless the protrusion 285 is overcome, the hooking portion 275 is difficult to detach from the hooked portion 284, thereby improving the assembly of the functional block.

  The support frame 25 is formed of a synthetic resin material in the shape of a rectangular frame that fits inside the holding member 27. The support frame 25 is fitted inside the holding member 27 so as to face the printed wiring board 262 of the human body detection unit 26 held by the holding member 27. That is, the support frame 25 is configured to support the printed wiring board 262 of the human body detection unit 26 in the holding member 27 (see FIG. 7). However, the support frame 25 is provided with holes 250 on both the left and right sides for passing an electric wire (output line) drawn from the printed wiring board 262 (see FIG. 7).

  The second cover body 29 is provided with an elongated through hole 2930 in the protruding wall 293 (see FIGS. 9 and 10). In the second cover body 29, the stepped screw 235 is inserted into the through hole 2930 provided in the protruding wall 293, and the threaded portion of the stepped screw 235 is screwed into the screw hole 2120 of the side plate 212 of the mounting member 21. Then, it is screwed to the mounting member 21 (see FIG. 10). The projecting portion 281 of the pedestal 28 is provided with a round hole 2810 through which the threaded portion of the stepped screw 235 is inserted, and the pedestal 28 is fixed to the side plate 212 by the stepped screw 235. That is, of the functional blocks, the human body detection unit 26 excluding the base 28, the holding member 27, the second cover body 29, and the support frame 25 are movable in the longitudinal direction with respect to the mounting member 21.

  Incidentally, it is known that the light emitted from the LED module 22 includes a wavelength component that attracts insects such as moths and mosquitoes. Therefore, the insect attracted by the light of the wavelength component enters the light source unit 2 through the gap between the cover 23 and the mounting member 21, and the dead body of the insect that has entered adheres to the inner wall of the cover 23 and loses its beauty. There is a problem of being. Moreover, in the light source unit 2 of the present embodiment, it is not easy for the user himself to remove the cover 23 from the mounting member 21 and clean it. Therefore, in the light source unit 2 of the present embodiment, it is desired to reduce the entry of insects into the cover 23. For example, as indicated by a solid arrow in FIG. 11, an insect may enter from a gap between the protruding wall 293 of the second cover body 29 and the side plate 212 of the attachment member 21.

  Therefore, in the light source unit 2 of the present embodiment, as shown in FIGS. 9 and 11, a pair of first standing walls 296 is provided on the second cover body 29. The first standing wall 296 is formed integrally with the curved surface 290 so as to face the protruding wall 293 with a predetermined distance on the back surface (upper surface) of the curved surface portion 290 and protrude upward. In a state where the functional block is attached to the attachment member 21, the tip (upper end) of each first standing wall 296 is in contact with the lower surface of the bottom plate 211 of the attachment member 21 (see FIG. 11). That is, when the tip (upper end) of the first standing wall 296 contacts the bottom plate 211 of the mounting member 21, a gap that can serve as an insect entry path can be reduced.

  Furthermore, in the light source unit 2 of this embodiment, as shown in FIG. 7, a pair of second standing walls 286 is provided on the base 28. The second standing wall 286 is formed so as to protrude upward along the front-rear direction from both ends in the left-right direction on the back surface (upper surface) of the main portion 280. In a state where the base 28 and the second cover body 29 are attached to the attachment member 21, the tip (upper end) of the second standing wall 286 is in contact with the lower surface of the bottom plate 211 of the attachment member 21 (see FIG. 11). In addition, the second standing wall 286 faces the first standing wall 296 in the left-right direction. However, at least one of the pair of second standing walls 286 and the first standing wall 296 may be in contact with at least one of the second standing walls 286 and the first standing wall 296. Note that the first standing wall may be provided on the holding member 27.

  As described above, in the light source unit 2 of the present embodiment, the space surrounded by the cover (second cover body 29) and the attachment member 21 is partitioned by at least one of the cover (second cover body 29) and the holding member 27. A first standing wall 296 is provided. The pedestal 28 is provided with a second standing wall 286 that faces the first standing wall 296.

  Since the light source unit 2 of the present embodiment is configured as described above, the first standing wall 296 and the second standing wall 286 can reduce gaps that can serve as insect entry paths. The first standing wall 296 and the second standing wall 286 make the path (gap) where the insect can travel become a maze-like state rather than a simple straight line or curve, so that the insect progresses into the functional block. Can hinder.

  FIG. 12 shows a perspective view of a functional block provided with a brightness detection unit instead of the human body detection unit. The brightness detection unit (not shown) is configured to detect (measure) the brightness (illuminance) of the illumination space from light incident through the first window hole 2710 provided in the bottom wall 271 of the holding member 27. The

  FIG. 13 is a perspective view of a functional block including a pull switch instead of the human body detection unit 26. The holding member 27 has a substantially frustoconical boss 277 protruding from the center of the bottom wall 271. A pull switch pull string (not shown) housed inside the holding member 27 hangs down through a through hole 2770 that passes through the center of the boss 277. The pull switch is inserted between the female connector 131 of the terminal block 13 and the male connector 243 of the power supply device 24, and is configured to alternately switch on and off each time the pull string is pulled downward. . That is, when the pull switch is on, the light source unit 2 is turned on by supplying power from the external power source (commercial power source) to the power supply device 24 via the pull switch. On the other hand, when the pull switch is off, the power supply to the power supply device 24 is stopped, so that the light source unit 2 is turned off. Therefore, the lighting fixture A of this embodiment has a pull switch as a functional component, and has an advantage that the usability can be improved because it can be switched on and off individually.

  By the way, in the human body detection unit 26 and the brightness detection unit, the power supply line and the output line for outputting the human body detection signal and the brightness detection signal from the signal processing circuit are drawn out from the printed wiring board 262. The human body detection signal and the brightness detection signal are input to the power supply device 24 via the output line.

  On the other hand, in the power supply device 24, the input cable 244 is drawn from one end side in the longitudinal direction of the storage case 242, and the output cable 245 is drawn from the other end side in the longitudinal direction of the storage case 242. Further, the power supply device 24 is provided with a signal input terminal on the side from which the output cable 245 is drawn.

  Therefore, the human body detection unit 26 and the brightness detection unit are arranged at the end portion closer to the signal input terminal of the power supply device 24 in the longitudinal direction of the mounting member 21, thereby increasing the wiring length of the output line 245. It can be shortened (see FIG. 14).

  On the other hand, the pull switch is arranged at the end portion (the end portion opposite to the human body detection unit 26 and the brightness detection unit) that is closer to the input cable 244 of the power supply device 24 in the longitudinal direction of the mounting member 21. Thus, the wiring length of the electric wire can be shortened (see FIG. 15).
