Embodiments for Carrying Out the Invention

[0009] Hereinafter, a lighting fixture according to an embodiment of the present disclosure will be described in detail with reference to the drawings. However, each of the drawings described in the following embodiments is a schematic diagram, and the respective ratios of the sizes and thicknesses of the respective components do not necessarily reflect the actual dimensional ratios. Note that the configurations described in the following embodiments are merely examples of the present disclosure. The present disclosure is not limited to the following embodiments, and various modifications can be made according to the design and the like as long as the effects of the present disclosure can be achieved.

[0010] (1) Overview As shown in FIGS. 1-3, a lighting fixture B1 according to an embodiment of the present disclosure includes a light source unit (light source unit A1), a fixture body 6, a lighting circuit unit (power supply unit 2), and a sheet-like IC tag 7.

[0011] The light source unit A1 irradiates illumination light. The fixture body 6 holds the light source unit A1. The power supply unit 2 lights the light source unit A1. The IC tag 7 stores information regarding at least one of the light source unit A1, the fixture body 6, and the power supply unit 2.

[0012] An antenna 72 and a control circuit 71 are formed on a first surface 701 of the IC tag 7, and an adhesive 73 is provided on a second surface 702 which is the back surface of the first surface 701 (see FIG. 4).

[0013] The information of the light source unit A1 stored in the IC tag 7 preferably includes, for example, a part number, a nominal value of luminous flux (unit: lumen), a manufacturing year, etc. Also, the information of the fixture body 6 stored in the IC tag 7 preferably includes, for example, a part number, a manufacturing year, etc. Further, the information of the power supply unit 2 stored in the IC tag 7 preferably includes, for example, a part number, electrical rated values (rated values of output voltage and output current, etc.), a manufacturing year, etc.

[0014] The information stored in the IC tag 7 can be read by a reader device (also called an RF reader). The IC tag 7 is preferably a passive type that does not incorporate a power source (battery). However, the IC tag 7 may be an active type that incorporates a power source (battery). The communication distance between the IC tag 7 and the reader device is determined by the frequency band of electromagnetic waves (radio waves) which is the communication medium, output power, size of the antenna, etc., and is about several cm to 10 m. That is, an operator can acquire information such as the part number of the lighting fixture B1 from a position several meters away from the lighting fixture B1 by using an appropriate reader device.

[0015] Here, in the embodiment, the IC tag 7 has an adhesive 73 provided on the back surface (second surface 702) of the first surface 701 on which the antenna 72 and the control circuit 71 are formed. Therefore, in the manufacturing process, for example, by pressing the second surface 702 against the surface of the appliance body 6 or the like, the IC tag 7 can be easily attached to the appliance body 6 or the like by the adhesive 73 provided on the second surface 702.

[0016] Thus, the lighting fixture B1 according to the embodiment can attach the IC tag 7 with a simple configuration.

[0017] (2) Details The lighting fixture B1 according to the embodiment (hereinafter abbreviated as the lighting fixture B1) includes, as shown in FIGS. 1 and 2, a light source unit A1 corresponding to a light source part, an appliance body 6 that holds the light source unit A1, and an IC tag 7. The light source unit A1 is detachably attached to the appliance body 6 directly attached to the ceiling. However, the appliance body 6 may be embedded in the ceiling. Alternatively, the appliance body 6 may be directly attached to the wall or embedded in the wall.

[0018] (2-1) Appliance body The appliance body 6 includes a long box-shaped accommodating part 60 with an open lower surface, a pair of reflecting plates 61 that project obliquely upward from the open end edges on both sides along the longitudinal direction of the accommodating part 60, and a pair of end plates 62 provided at both longitudinal ends of the accommodating part 60 and the pair of reflecting plates 61. Note that the accommodating part 60 and the pair of reflecting plates 61 are integrally formed by punching and bending a metal plate. However, the appliance body 6 may be configured only by the accommodating part 60 that does not include the pair of reflecting plates 61 and has both longitudinal ends closed by the pair of end plates 62.

[0019] The appliance main body 6 is installed on the ceiling S1 by inserting suspension bolts 90 into at least any two of the plurality of mounting holes 63 provided on the bottom surface (upper surface) of the housing portion 60, and tightening nuts 91 on these suspension bolts 90 (see Fig. 2). Also, a power cable 92 is inserted into any one of the plurality of power holes 64 provided on the bottom surface of the housing portion 60. However, when a plurality of lighting fixtures B1 are installed, another power cable for feed wiring may be inserted into another power hole 64. Further, as will be described later, another power cable for feed wiring may be inserted into a hole formed by cutting out a knockout portion 620 (see Fig. 2) provided on the end plate 62.

[0020] A terminal block 65 is attached to the bottom surface of the housing portion 60. The terminal block 65 is electrically connected to a power line 93. A power connector 94 is provided at the tip of the power line 93.

[0021] Thus, the power cable 92 inserted into the power hole 64 of the appliance main body 6 is electrically connected to the terminal block 65, and is electrically connected to the power unit 2 of the light source unit A1 via the terminal block 65, the power line 93, and the power connector 94.

[0022] Note that the housing portion 60 has a pair of hanging holes 600 and a pair of hanging portions 601 at positions near both ends in its longitudinal direction (see Fig. 2). The pair of hanging holes 600 are provided on the side wall at one end in the short direction of the housing portion 60. The pair of hanging portions 601 are arranged above the other end in the short direction of the housing portion 60 (see Fig. 2).

[0023] (2-2) Light source unit As shown in Fig. 2, the light source unit A1 includes a light source module 1, a power unit 2, a support member 3, a communication unit 4, and a cover 5.

[0024] (2-2-1) Light source module The light source module 1 has two substrates 11 and a large number of LEDs (Light Emitting Diodes) 10 mounted on the surface (lower surface) of each substrate 11. The LED 10, which is a light-emitting element, is, for example, a packaged white LED for lighting. However, the light-emitting element is not limited to an LED, and may be an organic electroluminescence element, a semiconductor laser element, or the like.

[0025] Each substrate 11 is formed in a long rectangular shape. A large number of LEDs 10 are mounted in a row at equal intervals along the longitudinal direction of each substrate 11 at the center in the short-side direction on the surface (lower surface) of each substrate 11 (see FIGS. 2 and 3). A large number of LEDs 10 are electrically connected in series or in series-parallel by printed wiring formed on the surface of each substrate 11. In addition, two sets of connectors 12 are mounted at one end in the longitudinal direction on the surface of each substrate 11 (see FIG. 2). The printed wiring formed on the surface of each substrate 11 is electrically connected via the two sets of connectors 12.

[0026] (2-2-2) Support member The support member 3 is formed in a long L-shape by a metal plate (see FIGS. 2 and 3). The support member 3 has a long rectangular bottom plate 30 and a pair of side plates 31 that rise upward from both ends along the longitudinal direction of the bottom plate 30. The light source module 1 is attached to the lower surface of the bottom plate 30 by a plurality of claws 301 cut up from the bottom plate 30 (see FIG. 3). The pair of side plates 31 project upward from both ends along the longitudinal direction of the bottom plate 30.

[0027] Furthermore, a through-hole 32 that penetrates the bottom plate 30 in its thickness direction (vertical direction) is provided at one end in the longitudinal direction of the bottom plate 30 (see FIG. 3). The through-hole 32 is formed by notching one end in the longitudinal direction of the bottom plate 30 into a rectangular shape. However, the through-hole 32 is not limited to a notch, and may be a hole that penetrates the bottom plate 30. Note that the through-hole 32 is formed at a position that does not overlap with the light source module 1 when viewed from the thickness direction of the bottom plate 30.

[0028] The support member 3 includes a pair of hanging brackets 37 that protrude outward from the support member 3 at one end in the short direction near both ends in the longitudinal direction (see Fig. 2). Further, the support member 3 includes a pair of hanging springs at the other end in the short direction near both ends in the longitudinal direction. The pair of hanging brackets 37 and the pair of hanging springs play a role in holding the light source unit A1 in the fixture body 6.

[0029] (2-2-3) Power Supply Unit The power supply unit 2 includes a power conversion circuit, a constant current circuit, a control circuit, a power supply case 21, etc. The power conversion circuit converts the AC power supplied from an external power source (commercial power system) via the power cable 92 into DC power. The constant current circuit steps down the DC voltage output from the power conversion circuit and applies it to the light source module 1, and adjusts the DC current flowing through the light source module 1. The control circuit controls the power conversion circuit so as to maintain the output voltage of the power conversion circuit at a constant DC voltage. Further, the control circuit controls the constant current circuit so that the DC current supplied from the constant current circuit to the light source module 1 matches the target value. Note that the control circuit changes the target value of the DC current supplied to the light source module 1 according to the dimming signal received from the communication unit 4, as will be described later. Note that the power conversion circuit, the constant current circuit, and the control circuit are constituted by a printed circuit in which various circuit elements are mounted on a printed wiring board.

[0030] The power supply case 21 is formed in a long box shape having an opening on the lower surface. The power supply case 21 houses the printed circuit constituting the power conversion circuit, the constant current circuit, and the control circuit. The power supply unit 2 is attached to the bottom plate 30 of the light source unit A1 so that the opening of the power supply case 21 faces the upper surface of the bottom plate 30 (see Fig. 2). In a state of being attached to the support member 3, most of the opening of the power supply case 21 is blocked by the bottom plate 30.

[0031] (2-2-4) Communication Unit The communication unit 4 has an antenna, a wireless circuit, and a case 43 (see Figs. 2 and 3). The communication unit 4 performs wireless communication using electromagnetic waves (for example, radio waves in the 920 MHz band or 2.4 GHz band) as a communication medium.

[0032] The wireless circuit and the antenna are formed on a T-shaped printed wiring board. The wireless circuit is formed on the wide portion of the printed wiring board. The antenna is composed of conductors formed on the narrow portion of the printed wiring board.

[0033] The wireless circuit extracts a wireless signal from the radio wave received by the antenna and acquires control information from the wireless signal. Further, the wireless circuit converts the control information into a dimming signal and transmits the converted dimming signal to the control circuit of the power supply unit. The control circuit of the power supply unit changes the target value of the direct current supplied to the light source module 1 according to the dimming signal received from the communication unit 4, thereby blinking (switching between lighting and extinguishing) and dimming the light source module 1.

[0034] As shown in FIG. 3, the case 43 includes a case body 430 and a case cover 431, both of which are synthetic resin molded bodies. The case body 430 is formed in a box shape with one side (the lower surface) open. The case cover 431 has a lid body 432 that closes the open surface (the lower surface) of the case body 430 and an antenna housing portion 434.

[0035] The antenna housing portion 434 is formed in a flat box shape. Further, the antenna housing portion 434 protrudes downward from the lower surface of the lid body 432 and is integrally formed with the lid body 432 so as to open on the upper surface of the lid body 432.

[0036] The case body 430 and the case cover 431 are engaged to form the case 43. The case body 430 houses the wide portion of the printed wiring board (the portion where the wireless circuit is formed). The antenna housing portion 434 of the case cover 431 houses the narrow portion of the printed wiring board (the portion where the antenna is formed).

[0037] Case 43 is fixed to the support member 3 (the bottom plate 30 thereof) in a state where the antenna housing portion 434 is inserted into the through portion 32 and protrudes downward from the lower surface of the bottom plate 30 (see FIG. 3). Note that the case 43 is fixed to the bottom plate 30 by screwing with two screws (tapping screws 436) (see FIG. 3).

[0038] (2-2-5) Cover The cover 5 includes a cover body 50 formed in a long semi-cylindrical shape, and a pair of cover ends 54 attached to both ends in the longitudinal direction of the cover body 50, respectively (see FIG. 2). The cover body 50 is formed of a synthetic resin having translucency, such as acrylic resin or polycarbonate resin.

[0039] The pair of cover ends 54 are formed in a semi-circular plate shape in plan view by a material having the same translucency as the cover body 50. The pair of cover ends 54 are attached to both ends in the longitudinal direction of the cover body 50, respectively. That is, both ends in the longitudinal direction of the cover body 50 are closed by the cover ends 54.

[0040] Here, the cover body 50 and the cover ends 54 are configured to diffuse the light (illumination light) emitted from the light source module 1. Specifically, by filling a filler having light diffusibility in the synthetic resin forming the cover body 50 and the cover ends 54 (or the entire cover 5), light diffusibility is imparted to the cover body 50 and the cover ends 54. Then, the light emitted from the light source module 1 (LED 10) enters the cover body 50 and the cover ends 54 from the inner surface (upper surface) of the cover body 50 and the cover ends 54, is diffused by the filler, and exits the cover 5 from the outer surface (lower surface) of the cover body 50 and the cover ends 54.

[0041] The cover 5 is attached to the support member 3 by hooking a part of the cover body 50 on the tips (upper ends) of the pair of side plates 31 of the support member 3 (see FIG. 1). The cover 5 attached to the support member 3 covers the light source module 1 supported by the bottom plate 30 of the support member 3.

[0042] (2-3)IC tag IC tag 7 includes a base 70, a control circuit 71, an antenna 72, an adhesive 73, a protective sheet 74, and a release paper 75 (see FIGS. 4A and 4B). The base 70 is formed of a film-shaped synthetic resin molded body.

[0043] The antenna 72 is a so-called pattern antenna composed of a conductor formed on the first surface 701 of the base 70 (see FIG. 4B).

[0044] The control circuit 71 is a surface-mounted integrated circuit including a memory, a controller, an analog front end, etc. The memory stores information described later. The controller reads (or reads and writes) information from the memory and causes the antenna 72 to transmit a radio signal including the read information. The analog front end transmits the radio signal received from the controller from the antenna 72 and creates an operating current for the controller using the radio wave received by the antenna 72. Note that the control circuit 71 is surface-mounted on the first surface 701 of the base 70.

[0045] The adhesive 73 is provided on the first surface 701 of the base 70 and the second surface 702 which is the back surface of the first surface 701 (see FIG. 4A). Note that the adhesive 73 provided on the first surface 701 and the adhesive 73 provided on the second surface 702 may be the same type of adhesive or different types of adhesives. For example, an adhesive may be used for the adhesive 73 provided on the first surface 701 to enable reattachment.

[0046] The protective sheet 74 is formed in a sheet shape of a material having electrical insulation properties (for example, paper or synthetic resin). The protective sheet 74 is attached to the adhesive 73 provided on the second surface 702 of the base 70. Also, the release paper 75 is formed of a piece of paper and is attached to the adhesive 73 provided on the first surface 701 of the base 70.

[0047] The memory of the IC tag 7 stores information regarding at least one of the light source unit A1, the fixture main body 6, and the power supply unit 2. Such information includes, for example, the part number, manufacturing year, manufacturer, electrical rating, etc. of the light source unit A1, the fixture main body 6, or the power supply unit 2. Also, the information regarding the light source unit A1 may include the nominal value of the luminous flux (unit: lumen), the light color (color temperature: unit: Kelvin), etc.

[0048] After the release paper 75 is peeled off, the IC tag 7 is attached to the surface to be attached, for example, the outer surface of the reflector 61 of the fixture main body 6, by the adhesive 73 provided on the first surface 701 (see Fig. 2). However, a plurality of IC tags 7 may be attached to one lighting fixture B1. For example, an IC tag 7 storing information regarding the fixture main body 6 may be attached to the fixture main body 6, an IC tag 7 storing information regarding the light source unit A1 may be attached to the light source unit A1, and an IC tag 7 storing information regarding the power supply unit 2 may be attached to the power supply unit 2.

[0049] Also, the IC tag 7 storing information regarding the light source unit A1 may be attached to, for example, the cover 5. Here, when the light source unit A1 includes the communication unit 4, a mark 55 indicating the position of the communication unit 4 is provided at one end in the longitudinal direction of the cover main body 50 (the end on the side where the communication unit 4 is arranged) (see Figs. 1 and 2). Therefore, if the IC tag 7 is attached at the position of this mark 55, there is an advantage that the IC tag 7 can be used as a mark. Alternatively, the IC tag 7 may be attached to the surface of the antenna housing portion 434 in the case 43 of the communication unit 4. If the IC tag 7 is attached to the surface of the antenna housing portion 434, there is an advantage that the IC tag 7 is less likely to be visually recognized from outside the cover 5.

[0050] (2-4) Procedure for collecting information of the IC tag The information of the IC tag 7 (the information written in the memory of the control circuit 71. The same applies hereinafter) can be collected by the following procedure. 1) Radio waves are irradiated from the reader / writer toward the IC tag 7. 2) The antenna 72 of the IC tag 7 receives radio waves, and the control circuit 71 is activated. 3) A radio signal containing the information stored in the memory of the control circuit 71 is transmitted from the antenna 72. 4) The reader / writer receives the radio signal. 5) The reader / writer acquires the information contained in the received radio signal and stores it in a memory or the like.

[0051] (3) Advantages of the Embodiment For example, there may be a case where a plurality (from several tens to several hundreds) of lighting fixtures B1 are installed in one building. In this case, it takes a great deal of man-hours to visually read information such as the product number, manufacturing year, and electrical rating of these plurality of lighting fixtures B1 from a nameplate or the like provided on each lighting fixture B1. Therefore, if the IC tag 7 storing information such as the product number, manufacturing year, and electrical rating is provided on the lighting fixture B1 as described above, the man-hours for collecting such information can be significantly reduced.

[0052] Moreover, in the IC tag 7 of the present embodiment, an adhesive 73 is provided on the second surface 702 which is the back surface of the first surface 701 (of the base 70) on which the antenna 72 and the control circuit 71 are formed. Therefore, in the manufacturing process of the lighting fixture B1 (the light source unit A1 and the fixture body 6), the IC tag 7 can be attached to an appropriate location of the lighting fixture B1. That is, the lighting fixture B1 has an advantage that the IC tag 7 can be attached with a simple configuration of providing the adhesive 73 on the second surface 702 of the base 70.

[0053] Note that the information stored in the IC tag 7 includes at least any one of the product number, manufacturing year, manufacturer, and electrical rating value of the lighting fixture B1 (the light source unit A1, the fixture body 6, the power supply unit 2, etc.). These pieces of information are often common to the information printed on the nameplate. Therefore, the lighting fixture B1 can save the trouble of visually recognizing the nameplate by storing the above information in the IC tag 7.

[0054] In addition, the information stored in the IC tag 7 may include information regarding the location where the appliance main body 6 is installed. The "information regarding the location" may be, for example, a position (coordinate) corresponding to a floor plan of the building in which the lighting fixture B1 is installed. Therefore, the lighting fixture B1 can inform what kind of lighting fixture is installed at which location in the building by storing the information of the installation location in the IC tag 7.

[0055] Furthermore, it is desirable to attach the IC tag 7 to at least any one of the appliance main body 6, the light source unit A1, and the power supply unit 2 of the lighting fixture B1. For example, in the case of the appliance main body 6 and the light source unit A1, since the IC tag 7 can be attached to a visible location from a distant position, the workability when reading information from the IC tag 7 can be improved. On the other hand, when attached to the power supply unit 2, there is an advantage that the appearance of the lighting fixture B1 is less likely to be impaired by the IC tag 7 because the IC tag 7 is not exposed.

[0056] Here, the lighting fixture B1 can further improve the workability when reading information from the IC tag 7 by attaching the IC tag 7 to the cover 5 of the light source unit A1.

[0057] Note that the lighting fixture according to the embodiment may be, for example, a lighting fixture such as a downlight, a spotlight, an emergency light, or a staircase light.
