Description

[Technical Field]

[0001] The present disclosure relates to lighting fixtures. [Background technology]

[0002] A conventional lighting fixture is described in Patent Document 1. This lighting fixture includes a light source, a power supply device that converts external AC power into DC power and steps it down to a predetermined voltage, a lighting circuit that turns on the light source, and a control circuit that controls the lighting circuit so that when a human presence sensor detects the presence of a person, the lighting circuit increases the dimming rate of the light source, and when the human presence sensor detects the absence of a person, the lighting circuit decreases the dimming rate of the light source after a delay time has elapsed. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-157073 Summary of the Invention [Problem to be solved by the invention]

[0004] The motion sensor is preferably disposed on the light-emitting side of the lighting fixture in order to detect people with high sensitivity. For this reason, the motion sensor is preferably attached to a sensor mounting part connected to the tips of multiple pillars extending from a base member disposed along the ceiling to the light-emitting side in the height direction (note that this sensor mounting structure using multiple pillars was not publicly known at the time of filing this application and is not prior art).

[0005] On the other hand, external power is supplied to the power supply unit via a power cable that electrically connects the adapter attached to the fixture mounting portion on the ceiling and the power supply unit mounted on the circuit board. The power cable is longer than necessary to allow the fixture body to be detached from the adapter, and has a long play.

[0006] In light of this background, if a person mistakenly routes a cord whose power line is covered with an insulating material around the radially outer side of a pole when installing a fixture, and then attaches the cord to a fixture mounting portion on a ceiling via an adapter, when the person rotates the fixture body relative to the adapter to correct the fixture position or detach the fixture body from the adapter, the cord may be stretched by the force from the pole, causing excessive tension in the cord and risk of damage. Therefore, an object of the present disclosure is to provide a lighting fixture that can prevent damage to a cord whose power line is covered with an insulating material for supplying power from an external source. [Means for solving the problem]

[0007] In order to solve the above problems, the lighting fixture of the present disclosure comprises a mounting part that is attached to a fixture mounting part provided on the ceiling of a building, a base member that is stationary relative to the mounting part and is arranged along the ceiling, one or more light-emitting elements mounted on a board that is stationary relative to the base member, a cord that extends from the mounting part (mounting part side) to the board side and has a power line for supplying power from outside that is covered with an insulating member, and an electrical appliance fixing member that has multiple pillar parts that extend from the base member side to the light emission side in the height direction and electrical appliance mounting parts connected to the tips of the multiple pillar parts, and the pillar parts have a cord detour prevention part that prevents the cord from detouring around the outside of the pillar part. [Effects of the Invention]

[0008] According to the lighting fixture of the present disclosure, it is possible to prevent damage to a power cord that is covered with an insulating member and serves as a power line for supplying power from an external source. [Brief explanation of the drawings]

[0010] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. It should be noted that, when multiple embodiments or variations are included below, it is anticipated from the beginning that new embodiments can be constructed by appropriately combining their characteristic features. In the following examples, the same components in the drawings are designated by the same reference numerals, and redundant explanations will be omitted. Furthermore, multiple drawings include schematic diagrams, and the dimensional ratios of the length, width, height, etc. of each component between different drawings do not necessarily match. Among the components described below, components not recited in the independent claims representing the highest concepts are optional components and are not essential components.

[0011] In the following description, when terms related to the vertical direction, such as below, above, lower side, and upper side, are used, they refer to the direction when the lighting fixture 1 is installed on a ceiling. Furthermore, when the "height direction" is referred to in the following description, the height direction refers to the height direction of the lighting fixture 1, and when the "orthogonal direction" is referred to, the orthogonal direction refers to a direction perpendicular to the height direction. Furthermore, the lighting fixture 1 of the embodiment has a shape that allows identification of a center and a radial direction in a plan view when viewed from the height direction. More specifically, the outer cover 30 of the embodiment has a dome shape with a through-hole 31 in the center and a circular ring shape in a plan view when viewed from below in the height direction. In the following description, when the "radial direction" is referred to, the radial direction refers to the radial direction of the outer cover 30. When the "inner" is referred to, the inner side refers to the radially inner side. When the "outer" is referred to, the outer side refers to the radially outer side.

[0012] Fig. 1 is a perspective view of a lighting fixture 1 according to an embodiment of the present disclosure as viewed from diagonally below, and Fig. 2 is a perspective view of the lighting fixture 1 as viewed from diagonally above. Fig. 3 is a perspective view of the lighting fixture 1 as viewed from diagonally below with the outer cover 30 removed, and Fig. 4 is a perspective view of the lighting fixture 1 as viewed from diagonally below with the inner cover 20 further removed from the state shown in Fig. 3.

[0013] 1 to 4, lighting fixture 1 includes an adapter 5 that forms a mounting portion to be attached to a fixture mounting portion (not shown) provided on the ceiling of a building, a base member 10 that is stationary relative to adapter 5 and is arranged along the ceiling, a light source (not shown) that emits light based on power supplied from the outside via adapter 5, an inner cover 20 that is arranged to cover the light source, an outer cover 30 that is arranged to cover inner cover 20, and one or more brackets 40 that support outer cover 30 and are attached to base member 10. Inner cover 20 and outer cover 30 are optical covers.

[0014] The base member 10 is made of a metal plate that is, for example, substantially annular in plan view when viewed from the height direction. In the lighting fixture 1, the inner cover 20 is engaged with the adapter 5 so as to be rotatable relative to the adapter 5, preventing the inner cover 20 from falling off the adapter 5. The inner cover 20 and the receiving fixture 40 are fixed to the base member 10 and are integrated with the base member 10. The outer cover 30 is engaged with the receiving fixture 40. The integrated structure of the lighting fixture 1 will be described in detail below.

[0015] As shown in FIG. 1 , the outer cover 30 has a dome shape with a through-hole 31 in the center, and has a circular ring shape in a plan view when viewed from below in the height direction. The outer cover 30 is made of a translucent resin material, such as polycarbonate, acrylic, or silicone. A portion of the human presence sensor 7 is housed within the through-hole 31 of the outer cover 30, and a sensor surface 7a of the human presence sensor 7 is exposed to the outside through the through-hole 31. The human presence sensor 7 is made of, for example, an infrared sensor, and detects the presence of a person by sensing infrared rays emitted from the human body. The fixing structure of the human presence sensor 7 will be described later.

[0016] As shown in FIG. 2, the adapter 5 has two connecting fittings 8. After inserting the two connecting fittings 8 into two fitting insertion holes provided in the fixture mounting portion on the ceiling, the adapter 5 is rotated to secure the adapter 5 to the fixture mounting portion, and the power supply unit and control unit of the lighting fixture 1 are electrically connected to an external power source via wiring within the adapter 5. The power supply unit converts external AC power into DC power and reduces the voltage to an appropriate level. DC power is constantly supplied to the human presence sensor 7. When the control unit receives a signal indicating that the human presence sensor 7 has detected a person, it turns on a switching unit for controlling the light source mounted on the power supply unit. This on control supplies power to the light source, causing the light source to emit light. The switching unit is composed of, for example, a transistor.

[0017] As shown in Fig. 3, the inner cover 20 defines a generally doughnut-shaped internal chamber 28. The inner cover 20 is made of a translucent resin material, such as polycarbonate, acrylic, or silicone. A light source is disposed within the internal chamber 28 of the inner cover 20. The inner cover 20 is a diffusion cover that diffuses light from the light source and distributes it toward the outer cover 30.

[0018] The inner cover 20 has an annular, plate-shaped flange portion 21 on its outer periphery. The flange portion 21 is provided on the upper outer edge of the inner cover 20 so as to protrude radially outward and extend circumferentially. Providing the annular flange portion 21 on the inner cover 20 can effectively seal the gap between the inner cover 20 and the base member 10, and can substantially reliably prevent light from leaking between the inner cover 20 and the base member 10. Instead of the annular flange portion 21, the inner cover 20 may have a plurality of plate-shaped flange portions arranged at intervals in the circumferential direction on its outer periphery. In this case, each flange portion is provided on the upper outer edge of the inner cover so as to protrude radially outward. It is preferable that each flange portion extend circumferentially.

[0019] The flange portion 21 has first thin-walled portions 21a and first thick-walled portions 21b that are thicker than the first thin-walled portions 21a, arranged alternately in the circumferential direction. The first thick-walled portions 21b include protrusions that protrude radially outward beyond the first thin-walled portions 21a. The first thick-walled portions 21b have threaded holes. The inner cover 20 is fixed to the base member 10 by fastening the screws 9 into the threaded holes of the first thick-walled portions 21b and then into threaded holes (not shown) in the base member 10. Because the screws 9 are fastened to the first thick-walled portions 21b, which have high rigidity, damage to the flange portion 21 caused by fastening the screws 9 can be effectively suppressed.

[0020] 4, the adapter 5 has a plurality of protrusions 5a at a height intermediate portion thereof, which protrude radially outward from its cylindrical outer circumferential surface and extend circumferentially. The inner cover 20 also has protrusions (not shown) on its inner circumferential surface, which protrude radially inward and extend circumferentially. By engaging the protrusions of the inner cover 20 with the protrusions 5a while positioned above the protrusions 5a, the inner cover 20 is engaged with the adapter 5 in a relatively rotatable state, preventing it from falling off the adapter 5.

[0021] As shown in Fig. 3, a human presence sensor holding member 70, which is an example of an electrical appliance fixing member, is fixed to the inner cover 20. The human presence sensor holding member 70 has a plurality of pillars 72 extending from the base member 10 side toward the light-emitting side in the height direction, and an annular holding portion 71, which is an example of an electrical appliance mounting portion, connected to the tips of the plurality of pillars 72. In this embodiment, the human presence sensor holding member 70 has a bridge structure including two pillars 72, and has a pair of pillars 72 formed integrally with the holding portion 71. The annular holding portion 71 holds the human presence sensor 7 in a manner that envelops it. When the human presence sensor 7 is held by the holding portion 71, the sensor surface 7a of the human presence sensor 7 protrudes downward beyond the holding portion 71.

[0022] The pair of pillars 72 are arranged on the same straight line across the center of the fixture in a plan view from the height direction. The holding portion 71 is located at the center of the fixture in a plan view from the height direction and is located below the inner cover 20 with a gap in the height direction relative to the inner cover 20. The pillars 72 are inclined with respect to the height direction so as to be displaced radially inward as they extend downward. A flat mounting portion 75 extending along the underside 22 of the inner cover 20 is provided at the end of the pillars 72 facing the inner cover 20. In this embodiment, the underside 22 and the mounting portion 75 extend in a substantially perpendicular direction. The mounting portion 75 is fixed to the inner cover 20 with a rivet 77, thereby fixing the human sensor holding member 70 to the light-emitting side of the inner cover 20.

[0023] The pillar portion 72 has one or more protruding portions 78 that protrude outward and extend in the extending direction of the pillar portion 72. In the example shown in Fig. 3, the one or more protruding portions 78 include a first rib 78a provided at one end of the pillar portion 72 in the width direction, and a second rib 78b provided at the other end of the pillar portion 72 in the width direction. The first rib 78a is an example of a first protruding portion, and the second rib 78b is an example of a second protruding portion. The first rib 78a and the second rib 78b are included in a cord detouring suppression portion that suppresses the second cord 55 from detouring around the outside of the pillar portion 72.

[0024] As shown in FIG. 4, the lighting device 1 includes a substrate 80 fixed to a base member 10. The substrate 80 is fixed to the underside of the base member 10 by fixing means such as screws or adhesive. The substrate 80 is provided with a through-hole 82 formed of a cylindrical hole or the like. A plurality of electronic components 81 that constitute a control device and a power supply device are mounted on the substrate 80. A plurality of LED (Light Emitting Diode) chips (not shown) are mounted on the substrate 80.

[0025] The light source is composed of multiple LED chips. The multiple LED chips are arranged radially outward from the adapter 5, for example, radially outward from the multiple electronic components 81. The multiple LEDs may be arranged at intervals in the circumferential direction on the circumference of a circle centered on the center of the fixture in a plan view when viewed from the height direction. Alternatively, the multiple LEDs may be arranged at intervals in the circumferential direction on each of two or more circles centered on the center of the fixture and having different diameters.

[0026] Next, the structure for fixing the holder 40 to the base member 10 and the structure for locking the outer cover 30 to the holder 40 will be described. Fig. 5 is a perspective view of the holder 40, and Fig. 6 is a perspective view of the fixing point of the holder 40 on the base member 10 as viewed from the radial outside. The holder 40 is made of resin. As shown in Fig. 6, the holder 40 has an internal chamber 41 that opens radially outward and to one circumferential side.

[0027] The receiver 40 further has a plurality of locking portions 42 that protrude upward and are spaced apart in the circumferential direction, and a cylindrical positioning portion 43 that protrudes upward. The locking portions 42 include a locking claw 42a that extends in the circumferential direction, and a connecting portion 42b that connects the locking claw 42a to a bottom plate 45 of the receiver 40 and extends in the height direction. The locking claw 42a includes a claw portion 42c that protrudes to the other circumferential side.

[0028] The bottom plate 45 of the receiver 40 is provided with a thin, flexible portion 46 with through holes around its periphery. The positioning portion 43 protrudes upward from the flexible portion 46. As shown in FIG. 6 , the base member 10 has a first through hole 10a through which the locking claw 42a can pass and a second through hole 10b formed as a cylindrical hole. The height of the first through hole 10a is approximately the same as the height of the connecting portion 42b. After the locking claw 42a passes through the first through hole 10a from below, the receiver 40 is moved relative to the base member 10 in one circumferential direction while the flexible portion 46 is elastically deformed upward. This causes the positioning portion 43 to fit into the second through hole 10b. In this state, the elastic deformation of the flexible portion 46 is released, and the connecting portion 42b is sandwiched between a pair of substantially parallel opposing surfaces on the inner circumferential surface of the first through hole 10a, and the claw portion 42c is engaged with the upper surface of the base member 10. The receiver 40 is attached to the base member 10 in such a structure and is positioned relative to the base member 10.

[0029] As shown in Fig. 5, the radially inner surface of the internal chamber 41 of the receiver 40 has a substantially V-shaped recess 47 in the circumferential center and a locking portion 48 that protrudes radially outward. On the other hand, as shown in Fig. 7, i.e., a perspective view of the outer cover 30 viewed obliquely from above, the outer cover 30 has a protrusion 33 at the upper end of its inner circumferential surface that has a shape corresponding to the recess 47 and protrudes radially inward.

[0030] The multiple brackets 40 are fixed to the base member 10 at intervals in the circumferential direction. In order to stably and reliably support the outer cover 30 with the brackets 40, the multiple brackets 40 are preferably arranged at approximately equal intervals in the circumferential direction, and it is preferable that the lighting fixture 1 includes three or more brackets 40 arranged at intervals in the circumferential direction. There are the same number of protrusions 33 as the number of brackets 40.

[0031] With the circumferential positions of the protrusions 33 different from the circumferential positions of the holders 40, the outer cover 30 is brought into contact with the underside of the base member 10 so as to cover the multiple holders 40. When the outer cover 30 is then rotated relative to the base member 10 in one circumferential direction, the outer cover 30 elastically deforms radially outward, causing the tapered tips of the protrusions 33 to climb over one circumferential end of the locking portions 48 and fit into the recesses 47. With this fit, the protrusions 33 are locked in the locking portions 48, and the outer cover 30 is fixed to the multiple holders 40.

[0032] 3, lighting fixture 1 has first cord 50 and second cord 55. First cord 50 has a structure in which two wires (not shown) are covered with insulating resin. One of the wires is a signal line that electrically connects human sensor 7 and a control device mounted on board 80, and the other wire is a power line that electrically connects human sensor 7 and a power supply device mounted on board 80.

[0033] The second cord 55 has a wiring (not shown) that supplies externally supplied power to the power supply device and an insulating member that covers the wiring. The second cord 55 extends from the adapter 5 side to the circuit board 80 side. More specifically, in this embodiment, the second cord 55 extends downward from the center of the underside of the adapter 5, which has a substantially cylindrical outer shape, and then passes through the inside of the second cord holding portion 53 and extends to a connector (electronic component) (not shown) mounted on the circuit board 80. The second cord 55 has a length longer than necessary to enable the appliance main body to be detachable from the adapter 5, and has a long play.

[0034] Next, the effects of the lighting fixture 1 will be described. As described above, the second cord 55 has a length longer than necessary to enable the fixture body to be detached from the adapter 5, and has a large clearance. In this context, as shown in FIG. 8, that is, a perspective view of the area around the motion sensor holding member 170 in the lighting fixture 101 of the reference example (not a prior art and not publicly known), if the post 172 does not have a protrusion that protrudes outward, the second cord 55 (not shown in FIG. 8) can easily be arranged so that it extends from the adapter 5 (not shown in FIG. 8) around the radially outer side of the post 172 and then to the circuit board side, and there is a risk that a person will erroneously select this wiring arrangement.

[0035] However, if the incorrect wiring arrangement is selected, when the fixture body is rotated relative to the adapter 5 in order to correct the fixture position or to remove the fixture body from the adapter 5, the second cord 55 will be stretched by the force from the pillar portion 172, and the tension in the second cord 55 will become excessive, which may result in damage to the second cord 55.

[0036] In contrast, in the lighting fixture 1, the pillar portion 72 has one or more protrusions 78 that protrude outward and extend in the extension direction of the pillar portion 72, making it difficult for people to select a wiring arrangement for the second cord 55 that detours from the adapter 5 around the radially outer side of the pillar portion 72 and then extends toward the board 80. This makes it possible to prevent damage to the second cord 55. Furthermore, because the pillar portion 72 has one or more protrusions 78 that protrude outward and extend in the extension direction of the pillar portion 72, the rigidity of the pillar portion 72 can be increased, making it possible to prevent breakage of the pillar portion 72. Furthermore, if the pillar portion 72 has a first rib 78a provided at one end on one side in the width direction and a second rib 78b provided at the other end on the width direction of the pillar portion 72, it is possible to more effectively prevent people from selecting a wiring arrangement for the second cord 55 that detours from the adapter 5 around the radially outer side of the pillar portion 72 and then extends toward the board 80, making it possible to effectively prevent damage to the second cord 55.

[0037] The present disclosure is not limited to the above-described embodiment and its modifications, and various improvements and modifications are possible within the scope of the claims of the present application and their equivalents. For example, the light source may be configured with a chip of a light-emitting element other than an LED chip, or may be configured with a chip of a semiconductor laser element, or a chip of a solid-state light-emitting element such as an organic EL (Electroluminescence) element or an inorganic EL element.

[0038] The post may have a protrusion disposed at the center of the post in the width direction, extending in the extension direction of the post, and protruding outward. The electrical appliance fixing member may have three or more post. The protrusions provided on the post do not have to be the protruding ribs 78a, 78b, and may have a shape such as a semicircular cross section. While the case where the human sensor 7 is fixed to the electrical appliance fixing member has been described, the electrical appliance fixed to the electrical appliance fixing member may also be a camera, a speaker, or the like. The post may have a curved shape that is convex outward (radially outward), and the entire post may be included in the cord detouring prevention portion. This also prevents the second cord from detouring around the outside of the post.

Configuration 5: The lighting device according to any one of configurations 1 to 4, further comprising an optical cover arranged to cover the light source, and the electrical appliance fixing member is fixed to the light output side of the optical cover. Configuration 6: The lighting fixture according to any one of configurations 1 to 5, wherein the pillar portion has an outwardly convex curved shape, and the entire pillar portion is included in the cord detouring suppression portion.
