Description

  The present invention relates to, for example, a sensor-equipped luminaire, and more particularly, to a sensor-equipped luminaire using an LED (Light Emitting Diode) as a light source.

  Among sensor-equipped luminaires, there is a luminaire in which the position of a control operation unit that controls the sensor is disposed on the inner surface of the reflector plate behind the glare cut angle (see, for example, Patent Document 1).

JP 2002-157916 A

  In a conventional lighting fixture with a sensor, a sensor circuit board, a sensor control circuit board, and the like are mounted along a reflecting surface of a deep (long) reflecting plate. This is because in a lighting fixture in which the light source is an incandescent bulb, a fluorescent lamp or the like, the length (height) of the light source itself is relatively long, so that the reflector also has a margin in the height direction. In such a lighting fixture, since there is a margin in the height direction, an operation unit for the operator to operate the control information of the sensor is provided behind the inner surface and the outer surface along the reflecting plate.

  However, in a lighting fixture using LED (light emitting diode) or EL (electroluminescence) as a light source, there is no need for a deep reflector that wraps the entire light source like conventional light sources such as incandescent bulbs and fluorescent lamps. . This is because in a lighting fixture using an LED or EL as a light source, the light source portion becomes small (thin) and becomes a shallow reflector. In such a shallow reflection plate, it is difficult to provide the operation unit on a surface along the reflection surface of the reflection plate, and there is a problem that the operability of the operation unit is inferior.

  Moreover, in the lighting fixture provided with an operation part in the back position along the reflective surface of a reflecting plate, in order to confirm how the operating part is set, the user approaches the lighting fixture and is in the back of the reflecting plate. The operation part must be checked. For this reason, the user had to climb a high platform or the like and check the operation unit inside the reflector of the lighting fixture attached at a high position.

  In addition, since the operation unit is provided in a deep position in the reflector, and the human sensor and the operation unit are not on the same plane, two substrates, a sensor substrate and an operation unit substrate, are required. And there was a problem in assemblability.

  An object of the present invention is to provide an operation unit on a surface substantially perpendicular to the irradiation axis direction of a light source, to make it easy to change the setting of the sensor unit, and to facilitate visual confirmation of the setting value of the sensor unit.

  The luminaire according to the present invention is a reflecting unit that reflects light emitted from a light emitter, the reflecting unit having an opening in the light irradiation direction, and the detection unit facing the light irradiation direction. A sensor unit installed near the periphery of the opening, and a control operation unit operated by an operator to input control information of the sensor unit, the control operation unit being arranged alongside the sensor unit It is characterized by that.

  A lighting apparatus 1000 according to the present embodiment will be described below with reference to FIGS. The lighting fixture 1000 of this Embodiment is a downlight etc. which are attached to a ceiling surface etc., for example.

  FIG. 1 is a perspective view of the luminaire 1000 as seen from the light irradiation direction side. As shown in FIG. 1, the lighting fixture 1000 includes a fixture body unit 100, a reflection unit 200 attached to the fixture body unit 100, and a sensor unit 300 attached to the reflection unit 200.

  The instrument body unit 100 includes an LED 110 that is a light source (a light emitter), a power supply unit 120 that lights the LED 110, and a housing unit (attachment) that houses and attaches the LED 110 and the power supply unit 120, and a heat dissipation unit 131 that radiates heat generated by the LED 110. The fixture main body 130 which has and the attachment spring 140 which latches the lighting fixture 1000 in attachment holes, such as a ceiling surface, are provided.

  As shown in FIG. 2, the LED 110 is a circular light source in which a plurality of LED elements are arranged in a circular shape. The LED 110 is not limited to a circle, but may be a square shape or a triangle shape. Moreover, the LED element which comprises LED110 may not be plural. Moreover, although LED110 uses LED as a light source (light-emitting body), other light sources, such as a discharge lamp, a fluorescent lamp, and an incandescent lamp, may be sufficient.

  As shown in FIG. 3, the power supply unit 120 includes a sensor control circuit unit 121 and a lighting control circuit unit 122. The power supply unit 120 supplies power to the sensor unit 300. In addition, the sensor control circuit unit 121 of the power supply unit 120 receives the detection signal and the control signal from the sensor unit 300, and outputs a lighting control signal for the LED 110 based on the input detection signal and control signal. The lighting control circuit unit 122 inputs a lighting control signal output from the sensor control circuit unit 121, and controls the lighting state of the LED 110 based on the input lighting control signal.

  Returning to FIG. 1, the reflection unit 200 includes a reflection part 210, a frame part 220, and a sensor attachment part 230.

  The reflector 210 reflects light emitted from the LED 110. The reflection unit 210 has an opening in the light irradiation direction. This opening is referred to as a reflection portion opening 250, the periphery of the reflection portion opening 250 is referred to as a peripheral portion 251, and the opening surface formed by the peripheral portion 251 is referred to as a reflection portion opening surface 252.

  The reflection unit 210 is provided in a skirt shape with the LED 110 as a vertex portion and extending from the vertex portion (LED 110) to the reflection portion opening 250 (periphery portion 251). The reflector 210 reflects the light emitted from the LED 110 and irradiates it in the light irradiation direction. However, the lighting fixture of the present embodiment can be applied in any shape as long as the reflecting portion (reflecting plate) has a shape in which the light irradiation direction is open.

  The frame part 220 is a frame-like part that protrudes outward from the end part (peripheral part 251) of the reflection part 210. When the fixture body 130 side of the lighting fixture 1000 is inserted into a mounting hole on the ceiling surface, the ceiling surface side of the frame portion 220 is formed so as to contact the ceiling surface.

  The sensor attachment portion 230 is a substrate attachment portion to which a sensor unit 300 (sensor circuit substrate 330 (see FIGS. 3 and 5)) described later is attached. One surface of the sensor attachment portion 230 (sensor attachment portion operation surface 231) is substantially flush with one surface of the frame portion 220 (or the reflection portion opening surface 252). In FIG. 3, the sensor attachment portion operation surface 231 is illustrated as being slightly closer to the LED 110 than the reflection portion opening surface 252, but may be on the same surface.

  The sensor attachment portion 230 is formed integrally with the reflection portion 210 by deforming a part of the reflection portion 210. The sensor attachment portion 230 is formed such that a part of the reflection portion 210 on the peripheral edge portion 251 side protrudes in a substantially box shape inside the reflection portion 210.

  Of the surfaces of the sensor mounting portion 230, the surface substantially flush with the reflecting portion opening surface 252 is the sensor mounting portion operation surface 231 described above. Of the surfaces of the sensor mounting portion 230, the surface that protrudes substantially perpendicular to the reflective portion opening surface 252 (or an angle that extends slightly outward from the substantially vertical) on the inner side of the reflective portion 210 is the sensor mounting portion vertical contact. Surface 232 (see FIG. 3). Among the surfaces of the sensor mounting portion 230, the surfaces on both sides of the sensor mounting portion standing surface 232 are sensor mounting portion side surfaces 233 and 234. The sensor attachment portion 230 has a box shape surrounded by the sensor attachment portion operation surface 231, the sensor attachment portion standing surface 232, and the sensor attachment portion side surfaces 233 and 234. One side of the sensor attachment portion operation surface 231 has a substantially arc shape along the peripheral edge portion 251 (the thick line portion in FIG. 2).

  As shown in FIG. 3 and FIG. 4, the reflection part 210 at a portion facing the sensor attachment part operation surface 231 of the sensor attachment part 230 is opened, and this opening is referred to as a sensor attachment part opening 238. A sensor unit 300 to be described later is attached to the sensor attachment portion 230 by being inserted into the sensor attachment portion opening 238 from the outside of the reflection portion 210 (the back side of the reflection portion 210 and the ceiling surface side of the reflection portion 210). As shown in FIG. 3, after the sensor unit 300 described later is attached to the sensor attachment portion 230, the sensor unit cover 240 is attached so as to cover the sensor attachment portion opening 238. Details of the method of attaching the sensor unit 300 to the sensor attachment portion 230 will be described later.

  The reflection part 210, the sensor attachment part operation surface 231, the sensor attachment part standing surface 232, and the sensor attachment part side surfaces 233 and 234 are continuously formed of the same material and do not hinder the light reflection performance of the reflection part 210. It has a configuration like this. The sensor attachment part 230 may be integrally formed with the reflection part 210, or may be configured as a separate part.

  As shown in FIGS. 2 and 3, the width L3 in the short side direction of the sensor attachment portion operation surface 231 is about one quarter to about one fifth of the radius L4 of the reflection portion opening surface 252. Alternatively, L3 is about one-half to about one-third of the length L6 of the reflector 210. As shown in FIG. 2, the width L5 in the long side direction of the sensor attachment portion operation surface 231 is about 3/4 to about 4/5 of the radius L4 of the reflection portion opening surface 252. By setting it as such a magnitude | size, it is considered so that the designability of the lighting fixture 1000 may not be impaired. Therefore, it is preferable that the sensor mounting portion 230 is as small as possible as long as the size of the sensor circuit board 330 to be mounted on the sensor mounting portion 230 allows. The width L5 in the long side direction of the sensor attachment portion operation surface 231 may be approximately one half or two thirds of the radius L4 of the reflection portion opening surface 252.

  As shown in FIG. 3, the width L1 of the reflection part 210 between the sensor attachment part operation surface 231 and the LED 110, the height L2 of the sensor attachment part standing surface 232, and the width L3 of the sensor attachment part operation surface 231 Are formed to be substantially the same. By forming in this way, when the luminaire 1000 is viewed from the irradiation direction side as shown in FIG. 2, there is a reflective portion 210 having a width of L1 between the sensor mounting portion operation surface 231 and the LED 110. The reflection performance of the reflection unit 210 is not disturbed. Since the sensor mounting portion standing surface 232 is formed at an angle so as to slightly open toward the reflection portion opening surface 252, the reflection performance of the reflection portion 210 is not hindered. In addition, the lengths of L1, L2, and L3 may not be substantially the same as long as they are formed so as not to hinder the reflection performance of the reflecting portion 210.

  When the reflection part opening surface 252 is not substantially circular, L3 of the sensor attachment part operation surface is about 1/2 to about 3 of the length L6 ′ (not shown) of the reflection part of the part forming the sensor attachment part. A fraction is preferred. The sensor attachment portion operation surface is preferably formed so that the sensor attachment portion operation surface does not cover the light source when viewed from directly below, and a reflection portion exists between the sensor attachment portion operation surface and the light source.

  The sensor mounting portion operation surface 231 has a substantially trapezoidal shape, and a lower side portion has a substantially arc shape along the peripheral edge portion 251. The sensor mounting portion operation surface 231 has a substantially rectangular shape whose long side is a substantially arc shape along the peripheral edge portion 251, a substantially square shape whose one side is a substantially arc shape along the peripheral edge portion 251, and a part of the circumference. A substantially elliptical shape that is substantially arc-shaped along the peripheral edge 251 may be used. Moreover, the bow shape which cut off a part of reflective part opening surface 252 with the straight line may be sufficient.

  When the sensor attachment portion operation surface 231 is arcuate, both ends of the sensor attachment portion operation surface 231 reach the peripheral portion 251 and both ends of the sensor attachment portion standing surface 232 reach the peripheral portion 251. The attachment portion side surfaces 233 and 234 are not necessary.

  5A is a front view of the sensor unit 300, FIG. 5B is a side view of the sensor unit 300 viewed from the short side direction, and FIGS. 5C and 5D show the sensor unit 300. FIG. FIG. 5E is a rear view showing the back surface of the sensor unit 300 as viewed from the long side direction.

  The sensor unit 300 includes a sensor 310 (sensor unit), a changeover switch 321 (sensor changeover switch), a changeover switch 322 (time changeover switch), a sensor circuit board 330, and a connector 340. The sensor unit 300 is a circuit board in which a sensor 310 (sensor unit), a changeover switch 321, a changeover switch 322, and a connector 340 are mounted on a sensor circuit board 330. Hereinafter, the sensor unit 300 may be referred to as a sensor circuit board 330.

  The sensor 310 is, for example, a human sensor that detects whether or not a person exists and outputs a detection signal. Alternatively, an illuminance sensor that detects the brightness of the room may be used.

  The changeover switch 321 is a switch for switching whether to activate a human sensor function that turns on the LED 110 when detecting a person by the sensor 310 and turns off the LED 110 when no person is detected. When operating the human sensor function, for example, the operator operates the changeover switch 321 to “ON”. Further, when the human sensor function is to be stopped (not operated), for example, the operator operates the changeover switch 321 to “OFF”.

  The changeover switch 322 switches the setting of time (for example, 0 minutes, 5 minutes, 10 minutes) from when the sensor 310 stops detecting a person to when the LED 110 is turned off.

  The changeover switch 321 and the changeover switch 322 are combined into a control operation unit 320. The changeover switches 321 and 322 of the control operation unit 320 include a slide type switch, a rotary type switch, a DIP (Dual In-line Package) switch, and the like. In this embodiment, a slide type switch is used. . Further, when the sensor unit 300 is attached to the sensor attachment portion 230, switch covers 321a and 322a are provided on the knob portion of the slide type switch (see FIGS. 1 and 7).

  The connector 340 is a component that connects the sensor unit 300 to the power supply unit 120. The sensor unit 300 supplies power from the power supply unit 120 via the connector 340. Alternatively, the sensor unit 300 transmits a detection signal and a control signal described later to the power supply unit 120 via the connector 340.

  The shape and size of the sensor circuit board 330 is preferably formed in accordance with the shape and size of the sensor mounting portion operation surface 231 of the sensor mounting portion 230.

  FIG. 6 is a functional block diagram showing functional blocks of the lighting fixture 1000 of the present embodiment.

  The power supply unit 120 includes a sensor control circuit unit 121 and a sensor control circuit unit 121. The sensor control circuit unit 121 inputs a detection signal output from the sensor 310 and a control signal set and output by the control operation unit 320. For example, the sensor 310 outputs a detection signal when a person is detected. The control operation unit 320 outputs a corresponding control signal when the changeover switches 321 and 322 of the control operation unit 320 are operated by the operator.

  The sensor control circuit unit 121 outputs a lighting control signal for turning on or off the LED 110 to the lighting control circuit unit 122 based on the input detection signal and control signal.

  For example, when the changeover switch 321 of the control operation unit 320 is in a state in which the human sensor function is activated (that is, “ON”), when the sensor 310 detects a person, the sensor 310 generates a detection signal indicating that the person has been detected. It outputs to the sensor control circuit unit 121 and outputs a lighting control signal for lighting the LED 110 to the lighting control circuit unit 122.

  Further, for example, the sensor control circuit unit 121 does not detect a person when the detection signal is not input from the sensor 310 for a predetermined time after the detection signal is input from the sensor 310, and the predetermined time elapses. The lighting control circuit unit 122 outputs a lighting control signal for turning off the LED 110. At this time, for example, when the time until the changeover switch 322 of the control operation unit 320 turns off the LED 110 is set to 5 minutes, the LED 110 is turned off after 5 minutes since the sensor 310 no longer detects a person. A lighting control signal is output.

  The lighting control circuit unit 122 turns on or off the LED 110 according to the lighting control signal input from the sensor control circuit unit 121.

  FIG. 7 is an exploded perspective view of lighting apparatus 1000 according to the present embodiment. The assembly process of the lighting fixture 1000 is demonstrated using FIG.

  (1) The instrument body 130 is attached to the reflection unit 200. The power supply unit 120 is stored in the instrument main body 130 in advance.

  (2) The switch covers 321a and 322a are inserted into the sensor mounting portion 230 of the reflection unit 200. As shown in FIG. 4, changeover switch holes 236 and 237 for projecting the changeover switch to the light irradiation direction side (side operated by the operator) are formed on the sensor attachment portion operation surface 231 of the sensor attachment portion 230. Is provided. The switch covers 321a and 322a are inserted into the changeover switch holes 236 and 237 so that the knob portion of the changeover switch protrudes to the side operated by the operator (light irradiation direction side).

  (3) The sensor unit 300 is inserted into the sensor attachment portion 230 so as to be substantially parallel to the sensor attachment portion operation surface 231, and the power supply unit 120 housed in the sensor unit 300 and the instrument body 130 is connected with the connector 340 (harness). Connecting.

  The sensor circuit board 330 (sensor unit 300) on which the sensor 310, the changeover switches 321, 322, and the connector 340 are mounted faces the mounting surface toward the light irradiation direction side (side operated by the operator), and operates the sensor mounting portion. The sensor mounting portion 230 is inserted so as to be substantially parallel to the surface 231. The solder surface of the sensor circuit board 330 faces the ceiling surface side. The sensor circuit board 330 is installed in the vicinity of the peripheral edge 251 of the reflection opening 250 so as to be substantially parallel to the reflection opening 252 (see FIGS. 1 and 2).

  The sensor 310 is inserted into a sensor hole 235 provided in the sensor attachment portion operation surface 231 shown in FIG. 4, and the tip portion of the sensor 310 protrudes from the sensor attachment portion operation surface 231 in the light irradiation direction. As shown in FIGS. 1, 3, etc., the sensor 310 is installed so as to be exposed from the sensor mounting portion operation surface 231 in the light irradiation direction. The sensor 310 is installed with the detection direction directed toward the light irradiation direction.

  The changeover switches 321 and 322 are arranged while inserting the knobs (tips) into the switch covers 321a and 322a. That is, the operator operates the knobs of the changeover switches 321 and 322 via the switch covers 321a and 322a.

  The sensor 310 and the control operation unit 320 (switch covers 321a and 322a) of the sensor unit 300 protrude from the inside of the frame unit 220 of the reflection unit 200 in the irradiation axis direction of the LED 110. That is, the changeover switches 321 and 322 (control operation unit 320) are arranged side by side with the sensor 310 in the vicinity of the peripheral edge portion 251 of the reflection opening 250 (see FIGS. 1 and 2). The control operation unit 320 (changeover switches 321 and 322) is disposed in front of the reflection unit opening surface 252 of the reflection unit 200.

  (4) After the sensor unit 300 is inserted into the sensor attachment portion 230, the sensor unit cover 240 is attached to the sensor attachment portion 230 with screws. The sensor unit cover 240 is attached so as to cover the sensor attachment opening 238 (see FIGS. 3 and 4).

  The sensor unit 300 is attached to the sensor attachment portion 230 of the reflection unit 200 by the process as described above.

  As shown in FIG. 2, in the present embodiment, a changeover switch 322 and a changeover switch 321 are arranged on both sides of the sensor attachment unit operation surface 231 around the sensor 310. 322 is arranged on one straight line. The arrangement of the sensor 310 and the changeover switches 321 and 322 is not limited to one straight line, and may be arranged at each vertex of the triangle as long as it is arranged on the sensor attachment portion operation surface 231. A plurality of sensors 310 may be arranged, and three or more changeover switches 321 and 322 may be arranged. If the number of changeover switches and the number of sensors increase, the sensors and switches may be arranged in a circular shape or a star shape. Further, the arrangement order of the sensor 310, the changeover switch 322, and the changeover switch 321 may be arranged with the changeover switches 321 and 322 next to each other without being centered on the sensor 310.

  As described above, the sensor-equipped luminaire of the present embodiment is a luminaire that is used by being embedded in a ceiling or the like. The reflector 210 reflects light emitted from a light source such as the LED 110 and the end of the reflector 210 ( A reflection unit 200 provided on the peripheral edge 251) and provided with a frame 220 in contact with the ceiling surface; and a sensor unit 300 accommodated in a portion of the reflection part (sensor mounting portion 230) in contact with the frame 220 of the reflection unit 200; The sensor unit 300 includes a sensor 310 (sensor unit) provided in parallel with the irradiation axis direction of the light emitted from the LED 100, and a control operation unit that switches functions when the sensor 310 detects. And the control operation unit are arranged on substantially the same plane.

  Next, the setting method (operation method) of the sensor control information of the sensor unit 300 in the lighting fixture 1000 of this Embodiment is demonstrated.

  As shown in FIG. 1, the changeover switch covers 321 a and 322 a protrude in the irradiation axis direction of the LED 110 from the inside of the frame portion 220 (the reflection portion opening surface 252) of the reflection unit 200. For example, the changeover switch covers 321a and 322a are slidable in the long side direction (see FIG. 5) of the sensor mounting portion operation surface 231. The change-over switches 321 and 322 can be switched by sliding the change-over switch covers 321a and 322a.

  Since the changeover switches 321 and 322 of the sensor unit 300 protrude in the irradiation axis direction of the LED 110 from the inside of the frame portion 220 (the reflection portion opening surface 252) of the reflection unit 200, the user (operator) is directly below the lighting fixture 1000. When looking up from the vicinity, it can be easily confirmed which position (what setting state) the change-over switches 321 and 322 are in. Therefore, the user (operator) does not need to climb on the stepladder or the like in order to confirm the setting state of the changeover switches 321 and 322 and the like disposed on the inside of the reflector plate of the lighting fixture 1000 or the back side of the ceiling.

  As described above, according to the lighting fixture of the present embodiment, since the control operation unit 320 is provided on a surface substantially perpendicular to the irradiation axis direction of the lighting fixture, it is easy to change the setting and to make visual confirmation easy. Can be.

  The changeover switches 321 and 322 of the sensor unit 300 are arranged alongside the sensor 310 on the sensor attachment portion operation surface 231 provided inside the frame portion 220 of the reflection unit 200, and the sensor attachment portion operation surface 231 to the LED 110. Thus, the sensor 310 of the sensor unit 300 and the control operation unit 320 (changeover switches 321 and 322) can be mounted on the same sensor circuit board 330.

  According to the lighting fixture of the present embodiment, the lighting control circuit unit 122 that turns on the LED 110 and the sensor control circuit unit 121 that drives and controls the sensor 310 are combined into one unit to configure the power supply unit 120 (see FIG. 3). Therefore, the outer shape of the lighting fixture 1000 can be reduced in size, and the image of the outer shape can be made substantially the same as a general lighting fixture that does not include the sensor 310.

  In the present embodiment, the case where the power supply unit 120 is an integrated unit including the sensor control circuit unit 121 and the lighting control circuit unit 122 has been described. However, the sensor control circuit unit 121 and the lighting control circuit unit are described. 122 may be divided into separate units and attached to the instrument main body 130, or may be separately attached to the instrument main body 130 and the reflection unit 200.

  Further, in the present embodiment, the case where the sensor unit 300 includes the sensor 310 (human sensor) and the control operation unit 320 has been described. However, instead of the sensor 310 (human sensor), the illuminance on the floor surface or the like An illuminance sensor that detects the above may be used. In the case where the sensor 310 is an illuminance sensor, the mode switched by the control operation unit 320 may be set by switching setting values of illuminance such as the floor surface. That is, the operator operates the control operation unit 320 to switch the setting value of illuminance to any of 1000 lx (lux): 750 lx: 500 lx, or to switch on / off the function for operating the illuminance sensor.

  In this embodiment, the case where an LED (light emitting diode) is used as a light source has been described, but EL (electroluminescence) or the like may be used.

  As described above, in the lighting fixture 1000 according to the present embodiment, the frame portion 220 is provided on the peripheral edge portion 251 of the reflection portion opening 250 of the reflection unit 200, and the sensor 310 (human beings) is oriented parallel to the irradiation direction of the LED 110. Sensor), and the control operation unit 320 can also be arranged on the same surface in the vicinity of the human sensor 310.

  Moreover, in the lighting fixture 1000 according to the present embodiment, since the control operation unit 320 and the sensor 310 are on the same surface, the control operation unit 320 and the sensor 310 can be mounted on one sensor circuit board 330. In addition, manufacturing costs and component costs can be reduced, and assemblability is improved.

Embodiment 2. FIG.
In this embodiment, a structure in which the sensor unit 300 of the lighting fixture 1000 shown in Embodiment 1 is movable will be described. In the present embodiment, the same components as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  8 is a cross-sectional view of the lighting fixture 1000a showing the present embodiment, FIG. 9 is a partially enlarged view of the lighting fixture 1000a shown in FIG. 8, and FIG. 10 shows the reflection unit 200 of the present embodiment inside (ceiling surface). It is a top view when it sees from the side.

  The lighting fixture 1000a includes a fixture body unit 100, a reflection unit 200 attached to the fixture body unit 100, and a sensor unit 300 attached to the reflection unit 200.

  The reflection unit 200 includes a reflection part 210 that reflects light emitted from the LED 110, a frame part 220 that protrudes outward from an end of the reflection part 210 (peripheral part 251 of the reflection part opening 250), and the frame part 220. Sensor mounting portion 230a provided inside (in the vicinity of the reflection portion 210 inside the peripheral edge portion 251).

  The sensor attachment portion operation surface 231 of the sensor attachment portion 230a is substantially flush with one surface of the frame portion 220 (the surface formed by the peripheral edge portion 251 of the reflection portion opening portion 250, that is, the reflection portion opening surface 252). . In FIG. 8, the sensor attachment portion operation surface 231 is illustrated as being slightly closer to the LED 110 than the reflection portion opening surface 252, but may be on the same surface.

  As shown in FIG. 9, the sensor attachment portion 230a includes a slide piece 291a, stopper pieces 292a and 293a, and a spring 290. The slide piece 291a attaches the sensor unit 300 so as to be slidable in the light irradiation direction and in the opposite direction (for example, the vertical direction). For example, as shown in FIG. 10, the slide piece 291a has a pair of slide pieces 291a having a width substantially equal to the width of the sensor circuit board 330 (dotted line) to be inserted ( Alternatively, it is formed to be slightly longer than the width of the sensor circuit board 330 (dotted line). In FIG. 10, two pairs of slide pieces (slide pieces 291a and 291b) are installed, and the sensor circuit board 330 is stably slid and slid in the opposite direction (for example, up and down direction). be able to.

  The stopper pieces 292a and 293a regulate the slide width L with which the sensor unit 300 slides. The sensor unit 300 slides between the slide widths L delimited by the stopper pieces 292a and 293a. The stopper piece includes a lower stopper piece 292a and an upper stopper piece 293a. Considering assemblability when the sensor unit 300 is inserted into the sensor mounting portion 230a, the upper stopper piece 293a is preferably provided on the sensor unit cover 240a. As shown in FIG. 10, the lower stopper piece 292a may be integrally formed with the slide pieces 291a and 291b, or may be attached as a separate part.

  The spring 290 presses the sensor circuit board 330 of the sensor unit 300 in the light irradiation direction. Therefore, when no external pressure is applied to the sensor 310, the sensor 310 protrudes from the reflecting portion opening surface 252 by a predetermined length m (for example, about 1 to 2 mm) and is stabilized. For example, when an external pressure is applied to the sensor 310 from the light irradiation direction side, that is, when an external pressure is applied to the tip of the sensor 310 in the P direction, the spring 290 is pushed by the sensor unit 300 and contracts, and the sensor 310 The tip moves to the back of the reflecting portion opening surface 252. The sensor attachment portion 230a of the present embodiment attaches the sensor unit 300 (sensor circuit board 330) so as to be slidable in the light irradiation direction and the ceiling surface direction (that is, the vertical direction). That is, the sensor unit 300 slides into the reflection unit 200.

  The sensor 310 is mounted in a state of protruding from the frame portion 220 (an end portion of the reflection unit 200) in order to maintain a sufficient area that can be detected by the sensor 310 (human sensor). That is, the sensor 310 is installed in a state where it protrudes from the reflection opening surface 252 (frame portion 220) by about 1 to 2 mm. For this reason, for example, when an external pressure is applied to the protruding sensor 310 by, for example, an operator placing the lighting fixture on the table with the reflection opening 250 facing down, the sensor 310 (sensor unit 300) may be directly pressed. There is. As described above, when an excessive force is applied to the sensor 310 (sensor unit 300), the sensor unit cover of the sensor mounting portion, the sensor circuit board, or the like may be destroyed.

  Since the spring 290 and the like are provided on the back surface (solder surface) of the sensor circuit board 330 of the sensor unit 300, even if an external pressure is applied to the sensor 310, the sensor 310 (sensor unit 300) is And the sensor 310 can be prevented from being damaged.

  Although the configuration using the spring 290 has been described in this embodiment, an elastic body such as natural rubber, an elastic resin, or a cushion material may be used instead of the spring 290.

  The sensor attachment portion 230a may be configured as a separate body without being integrally formed (configured) with the reflection unit 200 (reflection frame (frame portion 220)). When the sensor attachment portion 230a is separated from the reflection unit 200, the sensor 310 (sensor circuit board 330) may be movable, or the separate sensor attachment portion 230a itself may be movable.

Embodiment 3 FIG.
In the present embodiment, the shape of the sensor mounting portion 230 of the lighting fixture shown in the first embodiment is changed. In the present embodiment, the same components as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  FIG. 11 is a cross-sectional view of the lighting fixture 1000b showing the present embodiment, and FIG. 12 is a partially enlarged view of the lighting fixture 1000b shown in FIG.

  The lighting fixture 1000b includes a fixture body unit 100, a reflection unit 200b attached to the fixture body unit 100, and a sensor unit 300 attached to the reflection unit 200b.

  The reflection unit 200b includes a reflection part 210 that reflects light emitted from the LED 110, a frame part 220 that protrudes outward from the end part (peripheral part 251) of the reflection part 210, and the vicinity of the peripheral part 251 inside the frame part 220. And a sensor mounting portion 230b provided on the head.

  The sensor attachment portion operation surface 231b of the sensor attachment portion 230b is a position where the reflection portion opening surface 252 is lowered by one step from one surface of the frame portion 220 (the same surface as the reflection portion opening surface 252) to the back side (LED 110 side) of the reflection unit 200b. (See FIG. 12).

  As shown in FIG. 12, the sensor attachment portion operation surface 231b of the sensor attachment portion 230b is formed on the LED 110 side by a length k from the reflection portion opening surface 252. As a result, a frame step 228 (step k) is formed in the reflection unit 200b from the peripheral edge 251 of the portion where the sensor mounting portion 230b is formed to the sensor mounting portion operation surface 231b.

  The step k of the frame step portion 228 is formed to be substantially the same as or slightly longer than the length of the sensor 310 protruding from the sensor attachment portion operation surface 231b. Thereby, when the sensor unit 300 is accommodated in the sensor attachment part 230b, the front-end | tip part of the sensor 310 is prevented from protruding from the peripheral part 251 (or reflection part opening surface 252) of the frame part 220. FIG.

  As described above, the frame portion 220 around which the sensor 310 is disposed is made higher than the portion from which the sensor 310 protrudes, so that the space between the tip portion of the sensor 310 and the frame portion 220 (or the reflection portion opening surface 252). There is a gap. For this reason, for example, even when an operator places the lighting device 1000b on the floor or a desk with the frame portion 220 facing down, the sensor 310 is less likely to be subjected to external pressure, and the sensor 310 can be prevented from being damaged. .

  In the present embodiment, the case where the sensor attachment portion 230b is formed integrally with the reflection unit 200b (reflection frame (frame portion 220)) has been described. However, the sensor attachment portion 230b is separate from the reflection frame (frame portion 220). You may form as.

  Although the first to third embodiments have been described above, two or more of these embodiments may be combined. Alternatively, one of these embodiments may be partially implemented. Or you may implement combining two or more embodiment among these partially.
