BACKGROUND OF THE INVENTION
The present invention relates to a ceiling-mounted lighting fixture provided with a sensor, and more particularly to a lighting fixture in which the detection range of the sensor is variable.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, lighting fixtures configured to automatically turn on / off a light source using a human sensor or a brightness sensor are known. This type of sensor-equipped lighting fixture is widely used in entrances, toilets, hallways, and the like, for example, in the residential field. Furthermore, some lighting fixtures with a sensor of this type can adjust the detection range of the sensor in accordance with the form of the space in which the sensor is installed and the direction in which people enter and exit (for example, see Patent Document 1).
[0003]
The principal part of the lighting fixture disclosed by patent document 1 is shown in FIGS. The lighting fixture 9 is a ceiling-mounted incandescent lamp lighting fixture that is attached by using a hook-type wiring fixture R that is previously installed on the ceiling surface C, and is hooked on the hook-type wiring fixture R and electrically connected thereto. Connector 91, cylindrical lamp socket 92 coupled to the lower portion of connector 91, lamp 93 screwed into lamp socket 92, instrument body 94 inserted into connector 91 and covering connector 91, It is comprised by the substantially cylindrical shade 95 etc. which are hung on the lower side of the instrument main body 94. FIG.
[0004]
The connector 91 is configured by combining a cylindrical body 911 whose upper surface is open and a disc-shaped cover 912 that closes the upper surface of the body 911, and a pair of hooking blades 913 are formed on the upper surface of the cover 912. Projecting, and a hook-shaped piece 914 is projected from the upper peripheral edge of the body 911 over substantially the entire circumference.
[0005]
The instrument main body 94 includes a substantially circular mounting base 941 and a vertically long circuit housing portion 942 that is integrally formed so as to protrude from the side portion of the mounting base 941, and a sensor 943 is attached to the lower end of the circuit housing portion 942. . In the center of the mounting base 941, a cylindrical mounting cylinder 944 is formed in which the body 911 of the connector 91 is rotatably held. The body 911 of the connector 91 is inserted into the mounting cylinder 944 from above. Thus, the hook-shaped piece 914 of the connector 91 is positioned by contacting the upper end edge of the mounting cylinder 944. Then, a mounting plate 96 made of a thin metal plate is screwed to the upper surface of the instrument body 94. A fitting hole 961 into which the cover 912 of the connector 91 is fitted is formed in the mounting plate 96, and the connector 91 is interposed between the peripheral portion of the fitting hole 961 and the upper end edge of the mounting tube 944. And the attachment base 941 and the connector 91 are held rotatably with respect to each other.
[0006]
In other words, the lighting fixture 9 has the fixture body 94 on the ceiling surface C with the body 911 of the connector 91 as the rotation axis even after the connector 91 and the fixture body 94 are attached to the hook-type wiring fixture R on the ceiling surface C. Since it can be rotated in a parallel plane, the detection range of the sensor 943 can be adjusted by changing the orientation of the instrument main body 94 without preparing a special member separately.
[0007]

JP 2001-126527 A (page 3-9, FIG. 1-10)
[0008]
[Problems to be solved by the invention]
In the conventional lighting fixture 9, a hook-shaped piece 914 is formed on the outer peripheral edge of the connector 91 that is hooked to the hook-type wiring tool R, and this hook-shaped piece 914 is attached to the mounting tube 944 of the tool body 94. It is sandwiched and held between the upper edge and the peripheral portion of the fitting hole 961 of the mounting plate 96. Therefore, the structure of the portion that holds the connector 91 and the instrument main body 94 in a rotatable manner has to be larger than the size of the hook-type wiring instrument R, and as a result, the entire instrument becomes larger. Inevitable to do.
[0009]
Further, since the connector 91 and the instrument main body 94 are integrally coupled in advance via the mounting plate 96, and the whole is lifted together and attached to the hook-type wiring apparatus R, the operator can connect the hook-type connection. It is difficult to visually recognize the hooking surface of the tool 91, and it is difficult to hook the hooking blade 913 of the connector 91. Furthermore, since the upper surface is substantially flat when the fixture body 94, the connector 91, and the mounting plate 96 are integrated, if this is directly hooked on the hook-type wiring fixture R, the ceiling surface C and the lighting fixture 9 are A gap corresponding to the protruding dimension (height) of the hook-type wiring device R is formed therebetween. Since a small luminaire is usually attached to a narrow space such as a front door or a toilet, the hook-type wiring fixture R previously arranged on the ceiling is often a square hook ceiling. Since the square hook ceiling has a larger projecting dimension from the ceiling surface C (about 20 mm) than a ceiling-enclosed type hook rosette or the like, when a gap is formed between the ceiling surface C and the lighting fixture 9, The mounting state of the lighting fixture 9 becomes unsightly.
[0010]
The lighting fixture 9 has a structure in which the fixture main body 94 can freely rotate 360 degrees with respect to the connector 91 hooked on the hook-type wiring fixture R. However, the connector 91 to be hooked on the hook-type wiring device R and various circuits and switch elements stored in the circuit storage portion 942 of the device main body 94 must be wired by a connection cord (not shown). I must. If the connecting device 91 and the device main body 94 are left connected in a wired manner and the device body 94 is allowed to rotate freely with respect to the connecting device 91, an excessive burden such as pulling or twisting is applied to the connection cord, and the wire breaks. There is a risk of failure or electrical accident. Therefore, in the lighting fixture 9, in order to avoid such inconvenience, a connector 945 capable of attaching and detaching a connection cord is interposed between the connector 91 and the fixture main body 94 to attach the fixture main body 94 and the sensor 943. It is recommended that the connector 945 be removed each time the position is adjusted. However, such correspondence is inconvenient from a practical point of view, and the structure is complicated by the provision of the connector 945, resulting in an increase in product cost.
[0011]
The present invention has been made to solve these problems. The holding structure for rotating the position of the sensor is small, and it can be easily attached to a hook-type wiring device, and between the ceiling surface. It is another object of the present invention to provide a lighting apparatus that can be attached so as not to cause a gap.
[0012]
Furthermore, this invention makes it a solution subject to restrict | limit the rotation range of a sensor in this lighting fixture, and to prevent that an excessive mechanical burden is added to a connection cord, without depending on attachment / detachment of a connector.
[0013]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the structure of the lighting fixture of the present invention is a substantially cylindrical shape having a hooking blade that can be hooked on a hook-type wiring device provided on the ceiling surface on the upper surface and protruding downward at the center of the lower surface. A connector having a shaft-like shape, and attached to the shaft portion of the connector so as to project an arm to the side so that the shaft can be rotated around a plane parallel to the ceiling surface. A sensor holder that is supported, a sensor that is mounted in the vicinity of the tip of the arm of the sensor holder with the detection portion facing substantially downward, and a substantially cylindrical lamp socket that is coupled to the lower side of the sensor holder; A body cover attached to the lower side of the sensor holder to cover the hook-type wiring device, connector and sensor holder, a shade attached to the lower side of the body cover, and an outer peripheral surface of the lamp socket To support the shade and body cover A holder nut adhering the Rutotomoni body cover to the ceiling surface, characterized in that it comprises a lamp that is screwed into the lamp socket.
[0014]
According to the present invention, since the sensor holding tool for holding the sensor is attached to the shaft portion protruding from the center of the lower surface of the connector, the mechanical coupling structure for holding both rotations is extremely high. It becomes compact. Such a holding structure forms a male screw on the outer peripheral surface of the shaft portion of the connector, while forming a shaft hole with a female screw corresponding to the male screw on the shaft core of the sensor holder, By screwing the shaft hole, it can be configured rationally and economically.
[0015]
Further, according to the present invention, the main body cover is formed with a mounting hole through which the lamp socket can be inserted and a window hole through which the sensor detection portion can be exposed. A hooking claw that can be hooked on the edge of the mounting hole is formed.
[0016]
According to the present invention, after the connector, the sensor holder, the sensor, and the lamp socket, which are integrally joined together in advance, are hooked together on the hook-type wiring device, the main body cover and the shade formed separately from these Can be retrofitted. Therefore, it is easy to visually recognize the hooking surface of the hook-type wiring device when the connector is hooked on the hook-type wiring device, and the work is facilitated and the safety of the work is improved.
[0017]
Further, by allowing the main body cover to be retrofitted, the shape of the main body cover can be covered up to the hook-type wiring device together with the connector and the sensor holder. Therefore, the main body cover can be brought into close contact with the ceiling surface, thereby obtaining an attachment state having an excellent aesthetic appearance.
[0018]
Further, according to the present invention, the sensor holder is provided with two detents that interfere with the connector according to the rotation position, and the rotation range of the sensor holder is in a range of 90 degrees to less than 180 degrees. Characterized by being restrained.
[0019]
This invention is comprised so that the connector fixed with respect to a ceiling surface and the sensor holder which rotates with respect to a connector may not rotate unlimitedly. Thereby, it is possible to prevent an excessive mechanical load such as pulling or twisting from being applied to the connection cord wired between the connector and the sensor holder. The sensor itself usually has a detection range of about 50 to 80 degrees, and the connector can be attached to the hook-type wiring device by reversing the direction by 180 degrees. Therefore, the rotation restraint range of the sensor holder does not need to be 180 degrees or more, and about 90 degrees is sufficient for practical use. Even in this case, a detection range close to almost the entire circumferential direction of the lighting fixture is ensured. be able to.
[0020]
Further, according to the present invention, the arm of the sensor holder is bent obliquely upward near the tip, a sensor is attached to the bent portion, and the sensor has a normal axis with respect to the bent portion of the arm. It is characterized by being formed so as to be able to rotate within a certain angular range around the core.
[0021]
In the present invention, the sensor itself is formed to be rotatable so that the detection range of the sensor can be further finely adjusted, and the rotation axis thereof is inclined with respect to the rotation axis of the sensor holder. . Even in this case, if the center of the detection direction of the sensor is inclined with respect to the rotation axis of the sensor itself, the sensor can be made substantially vertically downward. Then, by rotating the sensor within an appropriate angle range on the left and right with the vertically downward position as the center, it is possible to adjust the detection range more finely according to the actual usage of the space.

In addition, the chain line shown with the code | symbol A in each figure is the center axis | shaft of this lighting fixture 1. FIG.
[0023]
The lighting fixture 1 includes a connector 10 connected to a hook-type wiring fixture R (in this example, a square hook ceiling) provided on a ceiling surface C, and a sensor that is rotatably attached to the connector 10. The holder 20, the sensor 30 attached to the sensor 20, the substantially cylindrical lamp socket 40 coupled to the lower side of the sensor holder 20, the hook-type wiring device R, the connector 10, and the sensor holder 20, a shade 60 attached to the lower side of the body cover 50, a holder nut 70 for attaching the shade 60 and the body cover 50 to the lamp socket 40, and screwing into the lamp socket 40. The lamp 80 is provided.
[0024]
The connector 10 is a box-shaped part that is approximately the same size as a square hook ceiling, a pair of hooking blades 11 that can be hooked to the hooking outlet of the hook-type wiring device R, and a lock that prevents dropping after hooking. A claw 12 is provided on the upper surface, and a release lever 13 for pulling down the lock claw 12 is provided on one side surface. Further, a substantially cylindrical shaft portion 14 projecting downward is formed at the center of the lower surface of the connector 10, and a male screw is formed on the outer peripheral surface of the shaft portion 14.
[0025]
The sensor holder 20 is a component made of a thin metal plate, and is formed by screwing a lower plate 25 having a pair of connecting legs 24 below the upper plate 21. The upper plate 21 has an arm 22 projecting sideways, and the vicinity of the tip of the arm 22 is bent obliquely upward (in this example, an elevation angle α = about 45 degrees with respect to a horizontal plane), and a sensor is provided at the bent portion. 30 is attached. A shaft hole 23 having a female screw is formed at the center of the base portion of the upper plate 21, and this shaft hole 23 is screwed into the shaft portion 14 of the connector 10. Thereby, the sensor holder 20 is supported so that it can rotate in a plane substantially parallel to the ceiling surface C around the shaft portion 14 of the connector 10. A corrugated washer 15 made of a thin spring steel plate is inserted into the shaft portion 14 of the connector 10, and the corrugated washer 15 is sandwiched between the lower surface of the connector 10 and the upper plate 21, so that the sensor holder Appropriate torque is applied to 20 rotations.
[0026]
The lower plate 25 of the sensor holder 20 is circular with the same diameter as the lamp socket 40, and a circular wiring hole 26 is formed at the center thereof. The lower plate 25 is attached via a connecting leg 24 so as to be separated from the shaft portion 14 of the connector 10. As shown in FIGS. 3 and 4, the connecting legs 24 are provided at asymmetric positions with respect to the central axis A, each extending upward from the outer edge portion of the lower plate 25, and the upper end portion thereof facing outward. It is bent to. The lower plate 25 is also formed with two opposing hook claws 27. Each hooking claw 27 rises upward from the outer edge portion of the lower plate 25 and protrudes further outward, and is formed in a substantially L shape in side view.
[0027]
In this embodiment, two fixing screws 28 for attaching the upper end portion of the connecting leg 24 to the upper plate 21 pass through the upper plate 21 and extend the tip to the side of the connector 10. Yes. Therefore, the tip of each fixing screw 28 interferes with the side surface of the connector 10 to prevent rotation, and the rotation of the sensor holder 20 with respect to the connector 10 is within the range of a central angle of about 90 degrees as shown in FIG. It will be restrained by. However, since the connector 10 can be hooked with its orientation reversed by 180 degrees with respect to the hook-type wiring device R, practically, as shown in FIG. 5, the two fan-shaped ranges Z1 and Z2 are opposed to each other. It is possible to adjust the position of the sensor 30 within the range.
[0028]
In other words, in this embodiment, in order to use the fixing screw 28 of the connecting leg 24 as a detent, the interference position between the connector 10 and the fixing screw 28 is determined from the required rotation range, and the connection is performed. The legs 24 are arranged asymmetrically as shown in FIG. However, the rotation stopper can be provided separately from the fixing screw 28. In this case, for example, the connecting legs 24 are arranged symmetrically, the tip of the fixing screw 28 is set to a length that does not interfere with the connector 10, and appropriate claw pieces, screws, etc. for preventing rotation are placed at two places on the upper surface of the upper plate 21. It should just project.
[0029]
The upper surface of the lamp socket 40 is fixed to the lower plate 25 of the sensor holder 20. A lamp mounting portion 41 to which a base of the lamp 80 can be screwed is opened at the lower end surface of the lamp socket 40. A male screw 42 to which a holder nut 70 can be screwed is formed on the outer peripheral surface of the lamp socket 40.
[0030]
The sensor 30 includes a circuit storage unit 31 fixed to a bent portion of the arm 22 in the sensor holder 20 and a detection unit 32 that is rotatably attached to the circuit storage unit 31. The circuit storage unit 31 stores a circuit board (not shown) equipped with various control circuits and switch elements for turning on and off the lamp 80. Four connection cords 33 are connected to the back side of the circuit housing portion 31, and these connection cords 33 are connected to the upper plate 21 via wiring guide holes 29 formed in the arm 22 of the sensor holder 20. From between the lower plates 25, the two on the power supply side are wired into the shaft portion 14 of the connector 10, and the two on the lamp 80 side are wired into the lamp socket 40. In the present invention, as described above, since the rotation of the sensor holder 20 with respect to the connector 10 is restricted within a certain angle range, an excessive mechanical load such as pulling or twisting is applied to these connection cords 33. Can be minimized.
[0031]
The detection unit 32 has a substantially semispherical outer shape, and a bowl-shaped lens 34 is attached to a part thereof. The detection unit 32 includes a brightness sensor that detects ambient brightness and a heat ray human sensor that detects the presence of a person. The operating conditions of these sensors are manually set by a switch 35 provided in the circuit storage unit 31. One of the two switches 35 shown in the figure is an operation mode changeover switch. For example, (a) a dimming standby mode by a sensor, (b) an automatic light-off mode by a timer, and (c) a wall switch direct connection mode in which the sensor is not operated. You can choose either. The other switch 35 is a lighting illuminance setting switch for setting the brightness when the human sensor is operated. For example, (a) sensing lighting at 60 lux, (b) sensing lighting at 20 lux, and (c) affecting the brightness. You can choose one of the test lights, which will not be.

The detection unit 32 of the sensor 30 rotates within an angle range within an inclined plane parallel to the bent portion of the arm 22 around the axis B in the normal direction to the bent portion of the arm 22 (see FIG. 6). As shown in FIG. 2, the axis B is inclined outward with respect to the central axis A of the luminaire 1 by the same angle as the elevation angle α of the bent portion of the arm 22. Further, the axial direction of the lens 34 is inclined with respect to the axis B by an appropriate inclination angle β (in this example, β = about 45 degrees). Therefore, the axial direction of the lens 34 can be changed in a range from a downward position as shown in FIG. 2 to a position close to the horizontal outward direction. In addition, an appropriate detection range angle γ (in this example, γ = about 50 degrees) is set for the lens 34 itself. In this way, the rotation axis (axial core B) of the detection unit 32 is inclined with respect to the central axis A of the luminaire 1, and the axial direction of the lens 34 is inclined with respect to the rotation axis of the detection unit 32. Thus, the detectable range of the sensor 30 has a sufficiently wide range. Therefore, even if the rotation of the sensor holder 20 with respect to the connector 10 is restricted within a certain range, practically detection in the entire circumferential direction is possible. Note that the above-described three types of angles (α, β, γ) can be appropriately changed within a range that does not impair practicality.
