Description

[Technical Field]

[0001] The present invention relates to a lighting fixture. [Background Art]

[0002] An elongated lighting fixture including a light source unit, a power supply unit for supplying electric power to the light source unit, and a metal support member that supports the light source unit and the power supply unit is known. Lighting fixtures of this type having a wireless communication function are known (for example, Patent Document 1). A lighting fixture having a wireless communication function includes a wireless module capable of performing wireless communication with an external device. The wireless module and the power supply unit are disposed, for example, on the back side of the support member (the side opposite to the light source unit side). [Prior Art Documents] [Patent Documents]

[0003] [Patent Document 1] Japanese Unexamined Patent Application Publication No. 2017-33709 [Summary of the Invention] [Problems to be Solved by the Invention]

[0004] Considering the assemblability of the power supply unit and the wireless module, when the power supply unit and the wireless module are disposed on the back side of the support member, it is preferable to dispose the power supply unit and the wireless module separately and spaced apart from each other.

[0005] However, disposing the power supply unit and the wireless module spaced apart from each other requires a large space in the region on the back side of the support member. In an elongated lighting fixture, since the region on the back side of the support member is narrow, it is difficult to dispose the power supply unit and the wireless module spaced apart from each other.

[0006] On the other hand, if the power supply unit and the wireless module are placed adjacent to each other, the assembly process of fixing the power supply unit and the wireless module to the support member becomes difficult. Specifically, if the wireless case housing the wireless module is placed adjacent to the power supply unit, problems may occur when fixing the power supply unit to the support member with screws or other fixing members, such as interference with the wireless case, making the assembly process of fixing the power supply unit to the support member difficult.

[0007] This invention has been made in view of the above problems, and aims to provide a lighting fixture in which the power supply unit can be easily fixed to a support member, even in a lighting fixture in which the power supply unit and the wireless case are arranged adjacent to each other. [Means for solving the problem]

[0008] To achieve the above objective, one embodiment of the lighting fixture according to the present invention comprises a light source unit, a power supply unit for supplying power to the light source unit, a wireless module housed in a wireless case for performing wireless communication relating to at least the control of the light source unit, and a support member for supporting the light source unit and the power supply unit, wherein the power supply unit is fixed to the support member by a fixing member, the wireless case is provided adjacent to the power supply unit, and the wireless case has a shape that avoids the fixing member. [Effects of the Invention]

[0009] Even in lighting fixtures where the power supply unit and wireless case are located adjacent to each other, the power supply unit can be easily fixed to the support member. [Brief explanation of the drawing]

[0011] Hereinafter, embodiments of the present invention will be described with reference to the drawings. All of the embodiments described below are specific examples of the present invention. Therefore, numerical values, constituent elements, arrangement positions and connection forms of constituent elements, as well as steps and the order of steps, etc. shown in the following embodiments are examples, and are not intended to limit the present invention. Accordingly, among the constituent elements in the following embodiments, constituent elements that are not described in the independent claims representing the most generic concept of the present invention will be described as optional constituent elements.

[0012] Each of the drawings is a schematic diagram, and is not necessarily strictly illustrated. In addition, in each drawing, substantially identical configurations are denoted by the same reference numerals, and overlapping descriptions are omitted or simplified. Furthermore, in each drawing, the X-axis, Y-axis, and Z-axis represent the three axes of a three-dimensional orthogonal coordinate system. In the present embodiment, the Z-axis direction is defined as the vertical direction, and the direction perpendicular to the Z-axis (the direction parallel to the XY plane) is defined as the horizontal direction. The X-axis and the Y-axis are axes that are orthogonal to each other and both orthogonal to the Z-axis. It should be noted that in this specification, the terms "upper" and "lower" do not necessarily refer to the upward direction (vertically upward) and downward direction (vertically downward) in absolute spatial perception.

[0013] (Embodiment) First, the configuration of the luminaire 1 according to the embodiment will be described with reference to FIGS. 1 to 5. FIG. 1 is a perspective view of the luminaire 1 according to the embodiment. FIG. 2 is an exploded perspective view of the luminaire 1. FIG. 3 is a cross-sectional view of the luminaire 1 taken along a plane parallel to the transverse direction of the luminaire 1. FIG. 4 is a cross-sectional perspective view of the luminaire 1 taken along the cross-section of FIG. 3. FIG. 5 is a cross-sectional view of the luminaire 1 taken along a plane parallel to the longitudinal direction of the luminaire 1. Note that FIG. 5 shows a portion on one end side in the longitudinal direction of the luminaire 1.

[0014] As shown in Figure 1, the lighting fixture 1 is a long base light overall, emitting a linear illumination light. The lighting fixture 1 in this embodiment is a dimmable and color-adjustable type of lighting fixture that can adjust the brightness and color of the illumination light. For example, the lighting fixture 1 can emit white light with any color temperature in the range of daylight to incandescent (6500K to 2700K) as illumination light. Alternatively, the lighting fixture 1 can emit light of a predetermined color, such as white light, as illumination light. In this embodiment, the lighting fixture 1 is used by being attached to a wiring duct 2 (lighting duct).

[0015] The wiring duct 2 is an example of a mounting member to which the lighting fixture 1 is attached, and is installed on building materials such as ceilings, beams, or walls in buildings such as facilities, shops, or residences. By being attached to the wiring duct 2, the lighting fixture 1 receives AC power (grid power, etc.) from the wiring duct 2. Note that the lighting fixture 1 is not limited to being installed on the wiring duct 2; it may also be mounted on building materials. In this case, the lighting fixture 1 will be directly attached to the building materials.

[0016] Lighting fixture 1 is an LED light fixture that uses an LED (Light Emitting Diode) as its light source. As shown in Figures 2 and 3, lighting fixture 1 comprises a light source unit 10, a power supply unit 20, a support member 30, a fixture body 40, and a cover member 50. The outer casing of lighting fixture 1 is formed by the support member 30, the fixture body 40, and the cover member 50. The support member 30 is positioned between the light source unit 10 and the power supply unit 20. In this embodiment, lighting fixture 1 is installed in the wiring duct 2 such that the light source unit 10 is on the floor side and the power supply unit 20 is on the ceiling side.

[0017] Furthermore, the lighting fixture 1 is a lighting fixture with wireless communication capabilities. Therefore, the lighting fixture 1 is further equipped with a wireless unit 60 including a wireless module 61 so that it can communicate wirelessly with the outside world. For example, the lighting fixture 1 can communicate wirelessly with external devices such as a wireless remote control (radio wave remote control) that has wireless communication capabilities.

[0018] The light source unit 10 emits light of a predetermined color. In this embodiment, the light source unit 10 emits white light as the illumination light for the lighting fixture 1. The light source unit 10 is also a long, linear light source and emits linear light. As described above, since the lighting fixture 1 is a dimmable and color-adjustable lighting fixture, the white light emitted by the light source unit 10 is controlled to have a color temperature of any color within the range of daylight to incandescent.

[0019] The light source unit 10 is an LED module using LEDs, and as shown in Figures 3 to 5, it has a substrate 11 which is a light source substrate and LED elements 12 arranged on the substrate 11.

[0020] The substrate 11 is a mounting substrate for mounting LED elements 12. In this embodiment, the substrate 11 is formed in a substantially rectangular shape that is elongated in the longitudinal direction (Y-axis direction) of the support member 30. The substrate 11 is, for example, a printed wiring board in which metal wiring is formed in a predetermined pattern. As the base material constituting the substrate 11, a resin substrate made of an insulating resin material, a ceramic substrate made of a sintered body of a ceramic material such as alumina, or a metal base substrate obtained by applying an insulating coating to the surface of a metal base material made of a metal material such as aluminum or copper, can be used. The substrate 11 may be a rigid substrate or a flexible film substrate.

[0021] The metal wiring formed on the circuit board 11 is electrically connected to the power supply unit 21 of the power supply unit 20. In this case, the electrodes or connector terminals formed on the circuit board 11 and the power supply unit 21 are connected by wires such as lead wires. The wires connecting the circuit board 11 and the power supply unit 21 are inserted, for example, through holes provided in the support member 30.

[0022] The substrate 11 is placed on the support member 30. The substrate 11 has a first surface on which the LED elements 12 are mounted, and a second surface facing away from the first surface. The first surface of the substrate 11 is the surface facing the cover member 50, and the second surface of the substrate 11 is the surface facing the support member 30.

[0023] LED elements 12 are arranged on the substrate 11. Specifically, multiple LED elements 12 are arranged on the first surface of the substrate 11. As shown in Figure 5, in this embodiment, the multiple LED elements 12 are mounted in a straight line along the longitudinal direction of the substrate 11 at predetermined intervals. Specifically, the multiple LED elements 12 are mounted along approximately the entire length of the substrate 11 in the longitudinal direction. Note that the multiple LED elements 12 may be mounted in multiple lines rather than a single line along the longitudinal direction of the substrate 11. The multiple LED elements 12 emit light due to the DC current supplied from the power supply 21 via wires connecting the power supply 21 to the substrate 11. The light emitted by the LED elements 12 (light source unit 10) passes through the cover member 50 and is emitted to the outside of the lighting fixture 1.

[0024] Each of the multiple LED elements 12 is an individually packaged surface mount device (SMD) type LED light source. Therefore, the light source unit 10 is an SMD type LED module.

[0025] The SMD-type LED element 12 comprises a white container (package) made of resin or ceramic, an LED chip (bare chip) placed inside the container, and a sealing member that seals the LED chip. In this embodiment, the LED element 12 is a white LED light source that emits white light. In this case, for example, a blue LED chip that emits blue light when energized is used as the LED chip, and a silicone resin (phosphor-containing resin) containing a yellow phosphor such as YAG is used as the sealing member that fills the container.

[0026] The light source unit 10, configured in this way, is placed on the support member 30. The light source unit 10 is placed on the first surface side, which is one side of the support member 30. The first surface side of the support member 30 is the front side, and in this embodiment, it is the floor side. On the other hand, the other surface of the support member 30 is the second surface, which is the back side, and in this embodiment, it is the ceiling side.

[0027] The light source unit 10 may also be a COB (Chip On Board) type LED module. A COB type light source module has a plurality of LED chips directly mounted on the substrate 11 and a sealing member (phosphor-containing resin) that seals the plurality of LED chips individually or collectively.

[0028] The power supply unit 20 is a power supply unit for supplying power to the light source unit 10. As shown in Figure 5, the power supply unit 20 has a power supply device 21 that generates power to make the light source unit 10 emit light, and a power supply case 22 that houses the power supply device 21.

[0029] The power supply unit 21 is composed of a power supply circuit that generates power to illuminate the LED elements 12 of the light source unit 10. For example, the power supply unit 21 converts AC power from an external power source such as a commercial power supply into DC power at a predetermined level by rectifying, smoothing, and stepping down the voltage. The DC power generated by the power supply unit 21 is supplied to the light source unit 10 via an electric wire. The power supply unit 21 may also be combined with a dimming circuit or a color adjustment circuit.

[0030] As shown in Figure 5, the power supply unit 21 has a circuit board 21a and a plurality of circuit elements 21b mounted on the circuit board 21a. The circuit board 21a is, for example, a printed circuit board in which metal wiring is formed in a predetermined pattern. Each of the plurality of circuit elements 21b mounted on the circuit board 21a is an electronic component for causing the light source unit 10 to emit light, and is, for example, a capacitive element (electrolytic capacitor, ceramic capacitor, etc.), a resistive element (resistor, etc.), a rectifier circuit element, a coil element, a choke coil (choke transformer), a noise filter, a diode, an integrated circuit element (IC), or a semiconductor element (FET, etc.).

[0031] The power supply case 22 is a metal or insulating resin housing (box) that houses the circuit board 21a on which the circuit elements 21b are mounted. In this embodiment, the power supply case 22 is a metal case. The power supply case 22 is formed into a predetermined shape by pressing or otherwise shaping a metal plate. Specifically, the power supply case 22 is a long, roughly rectangular housing with an opening.

[0032] The power supply unit 20, configured in this way, is positioned on the second side (the side opposite to the light source unit 10) of the support member 30. In other words, the power supply unit 20 is positioned on the back side of the support member 30. In this embodiment, the power supply unit 20 is positioned such that the opening of the power supply case 22 faces the support member 30.

[0033] Furthermore, the power supply unit 20 extends in the longitudinal direction of the support member 30 so as to straddle the longitudinal center of the support member 30. Specifically, the power supply case 22 extends in the longitudinal direction of the support member 30 so as to straddle the longitudinal center of the support member 30. In this embodiment, the longitudinal center of the power supply unit 20 and the longitudinal center of the support member 30 are approximately the same, but this is not limited to this. For example, the power supply unit 20 may be positioned biased toward one of the two ends of the support member 30 in the longitudinal direction. Also, the longitudinal length of the power supply unit 20 occupies about half of the longitudinal length of the support member 30, but this is not limited to this. For example, the longitudinal length of the power supply unit 20 may be 1 / 2 or less of the longitudinal length of the support member 30 (for example, about 1 / 3 or 1 / 4), or it may be 1 / 2 or more of the longitudinal length of the support member 30.

[0034] The power supply unit 20 is fixed to the support member 30. As shown in Figure 2, in this embodiment, the power supply unit 20 is fixed to the support member 30 by screws. The method of fixing the power supply unit 20 to the support member 30 will be described later. The power supply unit 20 may also be fixed to the support member 30 by fixing members other than screws.

[0035] As shown in Figures 3 to 5, the support member 30 is a long, metal base that supports the light source unit 10. In this embodiment, the support member 30 supports not only the light source unit 10, but also the power supply unit 20 and the cover member 50.

[0036] The support member 30 is a long metal member that extends in the longitudinal direction (Y-axis direction) of the lighting fixture 1. In this embodiment, the support member 30 is made of an aluminum alloy and is formed, for example, by extrusion molding. However, the material of the support member 30 is not limited to an aluminum alloy, and other metal materials may be used. Furthermore, the method of forming the support member 30 is not limited to extrusion molding. For example, the support member 30 may be formed into a predetermined shape by performing sheet metal processing such as roll forming and / or press forming on a metal plate.

[0037] As shown in Figure 3, the support member 30 has a roughly U-shaped cross-section and includes a bottom portion 31 and a pair of side portions 32 erected at the ends of the bottom portion 31. The bottom portion 31 and the pair of side portions 32 are flat and of the same thickness. In this embodiment, each of the bottom portion 31 and the pair of side portions 32 is rectangular in length. One of the pair of side portions 32 is provided at one end of the bottom portion 31 in the short direction, and the other of the pair of side portions 32 is provided at the other end of the bottom portion 31 in the short direction.

[0038] The bottom portion 31 is the area to which the light source unit 10 is attached. Specifically, the light source unit 10 is attached to the outside of the bottom portion 31 (the side with the cover member 50). The substrate 11 of the light source unit 10 is placed on the outer surface of the bottom portion 31. The cover member 50 is also attached to the bottom portion 31. Specifically, the cover member 50 is attached to the end of the bottom portion 31 in the shorter direction.

[0039] The pair of side sections 32 constitute the outer casing of the lighting fixture 1. The pair of side sections 32 sandwich the power supply unit 20 and the wireless unit 60. The fixture body 40 is fixed to the pair of side sections 32.

[0040] As shown in Figure 3, the main body of the device 40, when combined with the support member 30, forms a space for housing the power supply unit 20 and the wireless unit 60. The main body of the device 40 is a metal component, and when the support member 30 and the main body of the device 40 are combined, a cylindrical metal housing enclosed on all four sides is formed. The power supply unit 20 and the wireless unit 60 are housed in the internal space of this metal housing. In other words, the power supply unit 21 of the power supply unit 20 and the wireless module 61 of the wireless unit 60 are housed in the space formed when the main body of the device 40 and the support member 30 are combined.

[0041] The main body of the device 40 is fixed to the support member 30 such that it closes the opening of the support member 30, which has a roughly U-shaped cross-section. The main body of the device 40 is fixed to the support member 30 such that this opening faces the support member 30.

[0042] In this embodiment, the appliance body 40 has a roughly U-shaped cross-section and an opening. Specifically, the appliance body 40 has a top surface 41 and a pair of side surfaces 42 erected at the ends of the top surface 41. The top surface 41 and the pair of side surfaces 42 are flat and of the same thickness. In this embodiment, each of the top surface 41 and the pair of side surfaces 42 is rectangular in length. One of the pair of side surfaces 42 is provided at one end of the top surface 41 in the short direction, and the other of the pair of side surfaces 42 is provided at the other end of the top surface 41 in the short direction.

[0043] The top surface portion 41 is provided to cover the opening of the support member 30. The pair of side portions 42 face the pair of side portions 32 of the support member 30. Specifically, the pair of side portions 42 are in contact with the pair of side portions 32 of the support member 30.

[0044] As shown in Figures 3 and 4, the fixture body 40 is provided with a slit 40a. As shown in Figure 6, the slit 40a extends along the longitudinal direction of the fixture body 40. Figure 6 is an enlarged view of the area around the longitudinal end of the fixture body 40. In this embodiment, the slit 40a is in a straight line and extends parallel to the longitudinal direction (Y-axis direction) of the fixture body 40.

[0045] Furthermore, the slit 40a does not have to extend parallel to the longitudinal direction of the fixture body 40; it may extend parallel to a direction perpendicular to the longitudinal direction of the fixture body 40 (the short direction), or it may be inclined with respect to the longitudinal direction of the fixture body 40.

[0046] Here, the position of the slit 40a in the fixture body 40 will be explained using Figures 7 and 8. Figure 7 shows a top view of the lighting fixture 1 according to the embodiment. Figure 8 is an enlarged view of area VIII enclosed by the dashed line in Figure 7. In Figures 7 and 8, (a) shows the fixture body 40 attached to the support member 30, and (b) shows the fixture body 40 removed from (a).

[0047] As shown in Figures 7 and 8, the center of the slit 40a is located closer to the end of the support member 30 than the center of the power supply unit 20 in the longitudinal direction of the support member 30. Specifically, the entire slit 40a is located closer to the end of the support member 30 than the power supply unit 20 in the longitudinal direction of the support member 30. In other words, the slit 40a is formed to be located outside the power supply unit 20 with respect to the longitudinal center of the support member 30 (= the longitudinal center of the lighting fixture 1). More specifically, the slit 40a is formed on the longitudinal end side of the support member 30 than the power supply case 22 of the power supply unit 20.

[0048] This allows the slit 40a for wireless communication with the outside to be moved away from the power supply unit 20, thereby suppressing the shielding of wireless signals transmitted through the slit 40a by the metal components of the power supply unit 20. Consequently, the wireless performance of the wireless module 61 can be improved, resulting in a lighting fixture 1 with excellent wireless performance. This makes it easy to satisfy the target communication distance when performing wireless communication. Examples of metal components that shield wireless signals include the metal wiring of the circuit board 21a in the power supply device 21 of the power supply unit 20, or the metal parts of the circuit elements 21b mounted on the circuit board 21a.

[0049] The slit 40a is an opening for wireless communication with the outside. In this embodiment, the slit 40a functions as a slot antenna and electromagnetically couples with the antenna of the wireless module 61. For example, when receiving a wireless signal transmitted from the outside, the wireless signal generates an electric field in the short direction of the slit 40a. As a result, the slit 40a functions as an antenna and radiates the received wireless signal towards the antenna of the internal wireless module 61. Similarly, when the antenna of the wireless module 61 transmits a wireless signal, the wireless signal generates an electric field in the short direction of the slit 40a. As a result, the slit 40a functions as an antenna and radiates the wireless signal to the outside. The slit 40a, being a slot antenna, allows the wireless signal (electromagnetic wave) radiated from the antenna of the wireless module 61 to pass through due to the excitation of the antenna. For this reason, it is preferable that the slit 40a extends perpendicular to the excitation direction of the antenna of the wireless module 61.

[0050] Furthermore, in order for the slit 40a to function as a slot antenna, the antenna of the wireless module 61 should be located near the slit 40a. In other words, the slit 40a should be formed near the wireless module 61.

[0051] As shown in Figure 3, the slit 40a is formed in the vicinity of the wireless module 61, in the portion of the fixture body 40 that is exposed from the support member 30. Specifically, the slit 40a is provided on the top surface 41 of the fixture body 40. For example, the slit 40a is provided at the end of the top surface 41 in the short-side direction (width direction) of the fixture body 40. In this embodiment, the slit 40a is formed extending from the top surface 41 to the side surface 42. In other words, as shown in Figure 3, the slit 40a is formed to cut out the corner of the fixture body 40, which has a roughly U-shaped cross-section. Therefore, the slit 40a is located diagonally above the wireless module 61 in a cross-sectional view (XZ section) of the lighting fixture 1 in the short-side direction of the support member 30. Specifically, the slit 40a is located diagonally above the wireless module 61.

[0052] Furthermore, multiple slits 40a are formed in the device body 40. This improves the wireless performance (receiving sensitivity) of the wireless module 61. Specifically, as shown in Figures 6 and 8, two slits 40a are formed in the device body 40. At least a portion of the two slits 40a face each other in the short-side direction (X-axis direction) of the device body 40.

[0053] As shown in Figure 8, in a top view, at least one of the two slits 40a is preferably facing the wireless module 61. Specifically, in a top view, the slit 40a is preferably facing the substrate 61a of the wireless module 61. This improves the wireless performance (receiving sensitivity) of the wireless module 61. In this embodiment, in a top view, both slits 40a are facing the substrate 61a.

[0054] As shown in Figures 1 and 2, the fixture body 40 is provided with mounting members 70 for attaching the lighting fixture 1 to the wiring duct 2. In this embodiment, two mounting members 70 are provided along the longitudinal direction of the fixture body 40. Each mounting member 70 has a guide 71 that is inserted into a groove in the duct rail of the wiring duct 2, and a lever 72 with a locking portion that locks onto the duct rail of the wiring duct 2 when rotated. One of the two mounting members 70 has a connection structure for electrically connecting the wiring duct 2 and the power supply unit 20.

[0055] When attaching the lighting fixture 1 to the wiring duct 2, the guides 71 of each of the two mounting members 70 are inserted into the grooves of the duct rail of the wiring duct 2, and the levers 72 of each of the two mounting members 70 are rotated to lock the locking parts of each lever 72 to the duct rail. This allows the lighting fixture 1 to be held in place in the wiring duct 2, and AC power is supplied from the wiring duct 2 to the lighting fixture 1. The lighting fixture 1 can be removed from the wiring duct 2 by rotating the levers 72 in the opposite direction.

[0056] As shown in Figures 3 to 5, the cover member 50 covers the light source unit 10. In this embodiment, the cover member 50 covers both the light source unit 10 and the support member 30. The cover member 50 is formed in an elongated shape, similar to the light source unit 10 and the support member 30.

[0057] The cover member 50 is attached to the support member 30. Specifically, the cover member 50 is attached to the end of the bottom surface portion 31 of the support member 30 in the width direction.

[0058] The cover member 50 is an example of a light-transmitting cover, and transmits light emitted from the LED element 12 of the light source unit 10. In this embodiment, the cover member 50 is not only light-transmitting but also a diffuser cover. Therefore, the light from the LED element 12 incident on the cover member 50 is diffused (scattered) by the cover member 50 and then transmitted through the cover member 50.

[0059] The cover member 50 has a roughly U-shaped cross-section and, as shown in Figure 3, has a main surface portion 51 and a pair of side portions 52 erected at the ends of the main surface portion 51. The main surface portion 51 and the pair of side portions 52 are flat and have the same thickness. In this embodiment, each of the main surface portion 51 and the pair of side portions 52 is rectangular in length. One of the pair of side portions 52 is provided at one end of the main surface portion 51 in the short direction (X-axis direction), and the other of the pair of side portions 52 is provided at the other end of the main surface portion 51 in the short direction. Light emitted from the LED 12 passes through the main surface portion 51 and the side portions 52 and is emitted to the outside.

[0060] As shown in Figure 3, the length (width) of the cover member 50 in the short direction is the same as the length (width) of the support member 30 in the short direction. Therefore, the width of the main surface portion 51 of the cover member 50 and the width of the bottom surface portion 31 of the support member 30 are the same length, and the pair of side portions 52 of the cover member 50 and the pair of side portions 32 of the support member 30 are flush.

[0061] Furthermore, the cross-sectional shape of the cover member 50 is not limited to a roughly U-shape. For example, the cross-sectional shape of the cover member 50 may be curved in an arc shape. In this case, the cross-sectional shape of the cover member 50 can be a flattened, roughly semi-cylindrical shape or a cylindrical shape, etc.

[0062] The cover member 50 is made of a translucent resin material such as acrylic or polycarbonate, or a translucent material such as glass. In this embodiment, the cover member 50 is made of a translucent resin material. In this case, the cover member 50 can be a milky white cover member in which a light-diffusing material is dispersed inside. Such a cover member 50 can be manufactured by resin molding a translucent resin material mixed with a light-diffusing material into a predetermined shape. As the light-diffusing material, light-reflective fine particles such as silica particles can be used. The cover member 50 can be formed, for example, by extrusion molding.

[0063] The cover member 50 may be constructed not by dispersing the light diffusing material inside, but by forming a milky white light diffusing film containing the light diffusing material on the surface (inner or outer surface) of the transparent cover. Alternatively, the cover member 50 may be configured to have light diffusing properties by applying a diffusion process instead of using a light diffusing material. For example, the cover member 50 may be configured to have light diffusing properties by forming minute irregularities on the surface of the transparent cover by applying a surface treatment such as texturing, or by printing a dot pattern on the surface of the transparent cover. Even when the cover member 50 is subjected to a diffusion process, it may contain an additional light diffusing material to further enhance its light diffusing properties.

[0064] The cover member 50 and the support member 30 are fixed together to form a long cylindrical body. The light source unit 10 is housed inside this cylindrical body. As shown in Figures 1 and 2, end caps 80 are attached to each of the longitudinal ends of the cylindrical body formed by the cover member 50 and the support member 30.

[0065] The end cap 80 is provided to seal the open end of the cylindrical body, which is composed of the support member 30 and the cover member 50. In other words, the end cap 80 is attached to the cylindrical body so as to cover the open end of the cylindrical body, which is composed of the support member 30 and the cover member 50, thereby closing the open end of the cylindrical body. However, the end cap 80 does not completely seal the open end of the cylindrical body, which is composed of the support member 30 and the cover member 50, and there may be a small gap between the end cap 80 and the support member 30.

[0066] The end caps 80 are attached to each of the longitudinal ends of the cover member 50. In other words, the end caps 80 are cover ends provided at the ends of the cover member 50. The end caps 80 and the cover member 50 may be fixed together with an adhesive, or they may be fixed together with a locking structure such as a claw or recess formed on the end caps 80 and the cover member 50. The end caps 80 are made of, for example, a resin material. The end caps 80 may or may not be translucent.

[0067] As shown in Figures 3 to 5, the wireless unit 60 includes a wireless module 61 and a wireless case 62 that houses the wireless module 61. As shown in Figure 5, the wireless module 61 is electrically connected to the power supply unit 20's power supply device 21 by a connector wire 65.

[0068] The wireless module 61 is a wireless communication module for communicating wirelessly with the outside world. The wireless module 61 performs wireless communication at least related to the control of the light source unit 10. For example, the wireless module 61 receives wireless signals to control the light emission state of the light source unit 10. Specifically, the wireless module 61 receives wireless signals to turn the light source unit 10 off, on, dim, or adjust its color. The wireless signals received by the wireless module 61 are transmitted to the power supply unit 21 of the power supply unit 20 via the connector wire 65. This allows the power supply unit 21 to control the light source unit 10.

[0069] The wireless module 61 performs wireless communication based on wireless communication standards such as Wi-Fi®, Bluetooth®, or ZigBee®. For example, the frequency of the wireless signal received by the wireless module 61 is, for example, in the 2.4 GHz band or the 920 MHz band, but is not limited to these.

[0070] The wireless signals received by the wireless module 61 are transmitted from an external device, such as a wireless remote control having a wireless transmission function. The wireless remote control may be a portable device such as a smartphone, or a controller fixed to a wall or the like. The wireless remote control, which communicates wirelessly with the wireless module 61, is operated by the user. When the user operates the wireless remote control, a wireless signal for controlling the lighting fixture 1 is transmitted from the wireless remote control.

[0071] The wireless module 61 may also perform wireless communication other than wireless communication related to the control of the light source unit 10. For example, the wireless module 61 may receive or transmit wireless signals (pairing wireless signals) for pairing the wireless remote control with the lighting fixture 1. In this case, the wireless module 61 treats multiple lighting fixtures 1 that have already been paired with the wireless remote control as a single group and receives wireless signals (batch lighting control wireless signals) for simultaneously controlling multiple lighting fixtures 1 belonging to this group.

[0072] Here, the detailed configuration of the wireless unit 60 will be explained using Figures 9 to 11. Figure 9 is a perspective view of the wireless unit 60 from one direction, and Figure 10 is a perspective view of the wireless unit 60 from another direction. Figure 11 is an exploded perspective view of the wireless unit 60.

[0073] As shown in Figures 9 to 11, the wireless module 61 includes a board 61a which is a wireless board, an antenna 61b which receives wireless signals, and electronic components 61c (such as ICs) for processing the wireless signals received by the antenna 61b. The electronic components 61c may be one or more and are mounted on the board 61a.

[0074] The substrate 61a is a printed circuit board in which metal wiring is formed in a predetermined pattern. The antenna 61b is a patterned antenna formed in a predetermined pattern on one side of the substrate 61a. The antenna 61b is, for example, metal wiring such as copper.

[0075] For example, antenna 61b has a radiating conductor made of meander-shaped metal wiring and a grounded rectangular grounding conductor. The boundary between the radiating conductor and the grounding conductor is the feed point. The length of the radiating conductor should be formed to a length corresponding to the frequency of the wireless communication (wavelength of the electromagnetic wave). For example, if the wavelength of the wireless signal is λ, the length of the radiating conductor should be approximately λ / 4. Note that the shape of the radiating conductor is not limited to meander shape, but may be linear, L-shaped, spiral, or other linear shapes. Also, the shape of the grounding conductor is not limited to rectangular.

[0076] The antenna 61b configured in this way is electromagnetically coupled to the slot antenna, the slit 40a. In other words, antenna 61b is the primary excitation antenna, and the slit 40a functions as a secondary antenna. Antenna 61b receives and transmits wireless signals to the outside via the slit 40a. The wireless signals received by antenna 61b are converted into predetermined control signals (electrical signals) by a processing circuit composed of electronic components 61c and transmitted to the power supply unit 21 of the power supply unit 20 via the connector wire 65.

[0077] The wireless module 61 is fixed to the wireless case 62. Specifically, the inner surface of the wireless case 62 has a clamping portion that clamps the end of the substrate 61a of the wireless module 61, and the wireless module 61 is held in the wireless case 62 by sliding the substrate 61a so that the end of the substrate 61a is clamped into the clamping portion of the wireless case 62.

[0078] The wireless case 62 is made of a resin material that allows wireless signals to pass through. Examples of resin materials that can be used to make up the wireless case 62 include polycarbonate (PC) or polybutylene terephthalate (PBT). The wireless case 62 is a bottomed cylindrical box shape with an opening.

[0079] As shown in Figure 5, the wireless unit 60 configured in this way is positioned on the second side, which is the other side of the support member 30, similar to the power supply unit 20. In other words, the wireless module 61 is positioned on the second side of the support member 30. In this embodiment, as shown in Figure 3, the wireless module 61 is positioned so that the antenna 61b faces the side portion 32 of the support member 30. In other words, the wireless module 61 is positioned vertically so that the circuit board 61a stands upright on the bottom portion 31 of the support member 30. Furthermore, the wireless case 62 that houses the wireless module 61 is positioned so that the opening of the wireless case 62 faces the bottom portion 31 of the support member 30.

[0080] In this embodiment, the wireless unit 60 is adjacent to the power supply unit 20. That is, the wireless module 61 and the wireless case 62 are adjacent to the power supply unit 20. Specifically, the wireless unit 60 and the power supply unit 20 are arranged along the longitudinal direction of the support member 30.

[0081] As shown in Figures 2 and 5, the wireless unit 60 is fixed to the power supply unit 20. Specifically, the wireless case 62 is fixed to the power supply unit 20. In this embodiment, the wireless case 62 is provided so as to be in contact with the power supply unit 20. Specifically, the wireless case 62 is fixed to the power supply case 22 of the power supply unit 20 in a state of contact with the power supply case 22.

[0082] The wireless case 62 is fixed only to the power supply unit 20 and not to the support member 30. Furthermore, the wireless case 62 does not come into contact with the support member 30 and is floating above the bottom surface 31 of the support member 30. In other words, the open end of the wireless case 62 does not come into contact with the second surface of the support member 30. Also, the wireless module 61 housed in the wireless case 62 is floating above the support member 30. In other words, the wireless module 61 is housed in the wireless case 62 while floating above the support member 30.

[0083] As shown in Figure 8, the wireless unit 60 is fixed to the power supply unit 20 by screws 91 (first screws). Specifically, the wireless unit 60 is fixed to the power supply case 22 of the power supply unit 20 by screwing a part of the wireless case 62 to the power supply case 22 of the power supply unit 20 with screws 91.

[0084] Furthermore, the power supply unit 20 is fixed to the support member 30 by screws 92 (second screws). Specifically, the power supply unit 20 is fixed to the support member 30 by screwing a part of the power supply case 22 to the support member 30 with screws 92. Screws 91 and 92 are examples of fixing members.

[0085] Here, the fixing structure between the power supply unit 20 and the support member 30, and the fixing structure between the wireless unit 60 and the power supply unit 20 will be explained in detail with reference to Figure 12. Figure 12 is an exploded perspective view showing the fixing structure of the wireless unit 60 and the power supply unit 20.

[0086] As shown in Figure 12, the power supply case 22 of the power supply unit 20 is a long, sheet metal housing and has a first plate portion 22a which serves as the bottom plate of the power supply case 22, a pair of second plate portions 22b which are erected on the first plate portion 22a and extend in the longitudinal direction of the support member 30, and a pair of third plate portions 22c which are erected on the first plate portion 22a and connected to the longitudinal ends of the pair of second plate portions 22b.

[0087] A protruding piece 22d is provided at the lower end of the third plate portion 22c, which is formed to protrude outward. A screw hole 22e is formed in the protruding piece 22d through which a screw 92 for fixing the power supply case 22 to the support member 30 is inserted.

[0088] The wireless case 62 of the wireless unit 60 is adjacent to the power supply case 22. Therefore, to prevent the screws 92 from interfering with the wireless case 62 when fixing the power supply case 22 to the support member 30, the wireless case 62 has a shape that avoids the screws 92.

[0089] Specifically, as shown in Figure 8, the wireless case 62 has a notch 62a formed in a shape that avoids the screw 92 when viewed from above (a plan view when viewed from the direction in which the wireless case 62 and the support member 30 overlap) of the lighting fixture 1.

[0090] The notch 62a of the wireless case 62 is formed in a position that overlaps with the screw hole 22e of the protruding piece 22d of the power supply case 22. In other words, by providing the notch 62a in the wireless case 62, the screw hole 22e of the protruding piece 22d of the wireless case 62 is exposed when viewed from above the lighting fixture 1. As shown in Figures 9 to 11, the notch 62a is a recess created by partially indenting a part of the outer shape of the wireless case 62.

[0091] As shown in Figure 8, the notch 62a should be shaped to surround at least a portion of the screw 92 in a top view of the wireless case 62. In this case, the notch 62a should be shaped to surround the screw 92 from at least two directions or by two straight lines in a top view of the wireless case 62. That is, in this case, the notch 62a should be shaped to surround the screw 92 from three or more directions or by three or more straight lines in a top view of the wireless case 62. In this embodiment, the top view shape of the notch 62a is approximately trapezoidal, and it surrounds the screw 92 from three directions (by three straight lines).

[0092] Furthermore, as shown in Figure 12, a portion of the wireless case 62 protrudes toward the power supply case 22. This protruding portion of the wireless case 62 overlaps the first plate portion 22a of the power supply case 22. The protruding portion of the wireless case 62 has screw holes 62b through which screws 91 for fixing the wireless case 62 to the power supply case 22 are inserted.

[0093] The direction in which the screw 91 for fixing the wireless case 62 is screwed into the power supply case 22 and the direction in which the screw 92 for fixing the power supply case 22 is screwed into the support member 30 are the same, and in this embodiment, they are in the Z-axis direction. This makes it easy to fix the power supply unit 20 and the wireless unit 60 to the support member 30. In other words, the ease of assembly of the lighting fixture 1 can be improved.

[0094] Next, the method for fixing the power supply unit 20 and the wireless unit 60 to the support member 30 will be explained with reference to Figure 12, and using Figures 13 and 14. Figure 13 shows the state when the power supply unit 20 and the wireless unit 60 are fixed together. Figure 14 shows the state when the power supply unit 20 with the wireless unit 60 attached is fixed to the support member 30.

[0095] First, the power supply unit 20 and the wireless unit 60 are fixed together. Specifically, as shown in Figure 12, a screw 91 is inserted through the screw hole 62b of the wireless case 62 in which the wireless module 61 is housed, and the screw 91 is then screwed into the screw hole of the first plate portion 22a of the power supply case 22. This allows the wireless case 62 in which the wireless module 61 is housed to be fixed to the power supply case 22 in which the power supply unit 21 is housed, as shown in Figure 13. In other words, the wireless unit 60 can be fixed to the power supply unit 20. By fixing the wireless unit 60 and the power supply unit 20 together with the screw 91 in this way, the wireless unit 60 and the power supply unit 20 can be made into a single unit. Note that the wireless unit 60 and the power supply unit 20 are fixed together with two screws 91, but this is not the only method.

[0096] Next, as shown in Figure 14, the power supply case 22 of the power supply unit 20 to which the wireless unit 60 is fixed is fixed to the support member 30. Specifically, a screw 92 is inserted through the screw hole 22e of the protruding piece 22d formed on the power supply case 22, and the screw 92 is screwed into the screw hole 31a provided on the bottom surface 31 of the support member 30.

[0097] Although not shown in the diagram, a protruding piece with a screw hole is also formed on the opposite side of the longitudinal direction of the power supply case 22. Screws are inserted through these screw holes and screwed into the screw holes provided in the support member 30. This allows the power supply case 22, which houses the power supply unit 21, to be fixed to the support member 30.

[0098] In this case, since the wireless unit 60 is fixed to the power supply unit 20, by fixing the power supply unit 20 to the support member 30, the wireless unit 60 can also be fixed to the support member 30. In other words, the wireless unit 60 can be fixed to the support member 30 via the power supply unit 20.

[0099] As described above, in the lighting fixture 1 of this embodiment, the power supply unit 20 is fixed to the support member 30 by a screw 92 which is a fixing member, and the wireless case 62 that houses the wireless module 61 is provided adjacent to the power supply unit 20. The wireless case 62 has a shape that avoids the screw 92. Specifically, the wireless case 62 has a notch 62a formed in a shape that avoids the screw 92.

[0100] This configuration allows the power supply unit 20 to be easily fixed to the support member 30, even if the power supply unit 20 and the wireless case 62 are located adjacent to each other. This point will be explained in detail below.

[0101] When the power supply unit 20 and the wireless unit 60 are placed on the back side of the support member 30 (opposite side from the light source unit 10), it is preferable to place the power supply unit 20 and the wireless unit 60 separately, considering the ease of assembly of the power supply unit 20 and the wireless unit 60. In this case, a large space is required in the area on the back side of the support member 30 in order to place the power supply unit 20 and the wireless unit 60 separately.

[0102] However, in the case of a long lighting fixture 1 as in this embodiment, the area on the back of the support member 30 is narrow, making it difficult to place the power supply unit 20 and the wireless unit 60 separately. On the other hand, if the power supply unit 20 and the wireless unit 60 (wireless module 61) are placed adjacent to each other, the assembly work when fixing the power supply unit 20 and the wireless unit 60 to the support member 30 becomes difficult. Specifically, if the wireless case 62 that houses the wireless module 61 is placed adjacent to the power supply unit 20, problems such as the screws 92 interfering with the wireless case 62 when fixing the power supply unit 20 to the support member 30 may occur, making the assembly work when fixing the power supply unit 20 to the support member 30 difficult.

[0103] Therefore, in the lighting fixture 1 of this embodiment, a notch 62a is formed in the wireless case 62 to avoid the screw 92. With this configuration, when fixing the power supply unit 20 to the support member 30 with the screw 92, it is possible to avoid the screw 92 coming into contact with the wireless case 62, thereby suppressing interference between the screw 92 and the wireless case 62. Consequently, even if the power supply unit 20 and the wireless unit 60 are arranged adjacent to each other, the power supply unit 20 can be easily fixed to the support member 30.

[0104] Furthermore, in the lighting fixture 1 according to this embodiment, the notch 62a formed in the wireless case 62 is a recess created by partially indenting a part of the outer shape of the wireless case 62.

[0105] This configuration allows the screw 92 to be surrounded by the recessed portion 62a, thus enabling the screw 92 to be housed in the recessed portion 62a.

[0106] Furthermore, in the lighting fixture 1 according to this embodiment, the wireless case 62 is provided so as to be in contact with the power supply unit 20. Specifically, the wireless case 62 is provided so as to be in contact with the power supply case 22 of the power supply unit 20.

[0107] This configuration allows the wireless unit 60 and the power supply unit 20 to be integrated and attached to the support member 30. Furthermore, even if the wireless case 62 is brought into contact with the power supply unit 20, the notch 62a is formed in the wireless case 62, which effectively prevents interference between the wireless case 62 and the screws 92 when fixing the power supply unit 20 to the support member 30 with screws 92.

[0108] Furthermore, in the lighting fixture 1 according to this embodiment, the power supply unit 20 has a power supply case 22 that houses the power supply device 21, and the wireless case 62 is fixed to the power supply case 22. Specifically, the wireless case 62 is fixed to the power supply case 22 by screws 91.

[0109] This configuration allows the wireless unit 60 to be easily fixed to the power supply unit 20. In other words, the wireless unit 60 and the power supply unit 20 can be easily integrated using fixing members such as screws 91. This allows the wireless unit 60 and the power supply unit 20 to be easily attached to the support member 30.

[0110] Furthermore, in the lighting fixture 1 according to this embodiment, the wireless module 61 housed in the wireless case 62 is housed in the wireless case 62 in a state where it is suspended from the support member 30.

[0111] This configuration allows the wireless unit 60 and power supply unit 20, which are fixed to each other by screws 92, to be easily attached to the support member 30. Furthermore, by raising the wireless module 61 and wireless case 62 away from the support member 30, the wireless module 61 and wireless case 62 do not come into contact with the support member 30, thereby suppressing the generation of abnormal noise caused by contact between the circuit board 61a and wireless case 62 of the wireless module 61 and the support member 30.

[0112] (modified version) Although the lighting fixture according to the present invention has been described above based on embodiments, the present invention is not limited to the above embodiments.

[0113] For example, in the above embodiment, the top view shape of the notch 62a formed in the wireless case 62 was substantially trapezoidal, but it is not limited to this. For example, as in the wireless case 62A shown in Figure 15, the top view shape of the notch 62aA may be rectangular, or as in the wireless case 62B shown in Figure 16, the top view shape of the notch 62aB may be a part of a circle (a semicircle in Figure 16). In other words, the notch 62aC may be a shape that surrounds the screw 92 with a curve rather than a straight line in the top view of the wireless case 62C.

[0114] Furthermore, in the above embodiment, the notch 62a formed in the wireless case 62 was a recess created by partially recessing a part of the outline of the wireless case 62, but it is not limited to this. For example, instead of partially recessing a part of the outline of the wireless case 62, the notch 62aC may be a shape created by cutting off a corner of the wireless case 62C, as shown in Figure 17. In this case, as shown in Figure 17, the top view shape of the notch 62aC can be triangular. In other words, the notch 62aC may be a shape that surrounds the screw 92 from one direction or surrounds it with a single straight line when viewed from above the wireless case 62C. Also, as shown in Figure 18, the top view shape of the notch 62aD may be a part of a circle (in Figure 18, a sector with a circular angle of 90°).

[0115] Furthermore, in the above embodiment, the notch 62a formed in the wireless case 62 was a recess formed by indenting a part of the outer shape of the wireless case 62, but it is not limited to this. For example, as shown in Figure 19, the notch 62aE may be a through hole formed in the wireless case 62E.

[0116] Furthermore, in the above embodiment, the wireless unit 60 was directly fixed to the power supply unit 20 by the wireless case 62 to the power supply case 22, but this is not limited to this. For example, the wireless unit 60 may be indirectly fixed to the power supply unit 20 by another component such as a mounting bracket. Specifically, a sheet metal mounting bracket having a strip-shaped portion (line portion) and a mounting portion with screw holes is used, and the wireless case 62 is held in place by the mounting bracket by the strip-shaped portion of the mounting bracket, and the wireless case 62 is pressed against the power supply case 22 by the mounting bracket, and a screw 91 is inserted through the screw hole formed in the mounting portion of the mounting bracket and screwed into the screw hole of the power supply case 22. In this way, the mounting bracket can be screwed to the power supply case 22 by the screw 91, so that the wireless case 62 held by the mounting bracket can be indirectly fixed to the power supply case 22. In this case as well, the wireless case 62 is provided with a notch 62a formed in a shape that avoids the screw 92.

[0117] Furthermore, in the above embodiment, the slit 40a for wireless communication with the outside was formed in the fixture body 40, but this is not limited to this. Specifically, the slit for wireless communication with the outside of the lighting fixture may be formed in the support member 30. In this case as well, the center of the slit is located closer to the end of the support member 30 than the center of the power supply unit 20 in the longitudinal direction of the support member 30. Also, the slit for wireless communication with the outside of the lighting fixture may be formed in both the fixture body 40 and the support member 30. In other words, the slit for wireless communication with the outside only needs to be formed in at least one of the support member 30 and the fixture body 40. For example, when the slit for wireless communication with the outside is formed in the support member 30, the slit for wireless communication with the outside can be formed in the side portion 32 of the support member 30. In this case, the slit formed in the side portion 32 should face the wireless module 61 in the short direction of the support member 30. This can improve the wireless performance (receiving sensitivity) of the wireless module 61, so that a lighting fixture 1 with excellent wireless performance can be obtained. The slits formed in the side portion 32 may be formed in each of the pair of side portions 32, or they may be formed in only one of the pair of side portions 32.

[0118] Furthermore, although the cross-sectional shape of the support member 30 and the device body 40 was U-shaped in the above embodiment, it is not limited to this. For example, the cross-sectional shape of the support member 30 and the device body 40 may be L-shaped or I-shaped.

[0119] Furthermore, in the above embodiment, the two slits 40a were formed only on one side in the longitudinal direction of the fixture body 40 (the longitudinal direction of the support member 30), but this is not limited to this. For example, two slits 40a (a total of four slits 40a) may be formed on both sides in the longitudinal direction of the fixture body 40. In this case, it is preferable to form the pair of two slits 40a so as to be symmetrical with respect to the center of the fixture body 40 in the longitudinal direction of the fixture body 40 (i.e., the longitudinal direction of the support member 30). In other words, it is preferable that the four slits 40a are located in positions that are symmetrical with respect to the longitudinal direction of the support member 30. This eliminates the orientation of the fixture body 40 relative to the support member 30, so that the fixture body 40 can be attached to the fixture body 40 regardless of whether it is positioned to the left or right. Therefore, the fixture body 40 can be easily assembled to the support member 30. Note that in this case, the number of slits 40a is not limited to four. Specifically, if the number of slits 40a is 2n (where n is an integer greater than or equal to 1), then it is preferable that the 2n slits 40a are located in positions that are symmetrical with respect to the longitudinal direction of the support member 30.

[0120] Furthermore, although the cover member 50 in the above embodiment had both diffusive and light-transmitting properties, it is not limited to this. For example, the cover member 50 may be a light-transmitting cover that has only light-transmitting properties among diffusive and light-transmitting properties.
