Description

  The present invention relates to a luminaire and a lighting device, and more particularly to a direct-to-ceiling luminaire directly mounted on a ceiling and a luminaire including the luminaire.

  Conventionally, a ceiling-mounted downlight is known as a luminaire installed on a ceiling. The in-ceiling downlight is installed on the ceiling by embedding the light source mounted instrument body in the opening of the ceiling.

  However, in the case of installing a ceiling-embedded downlight on a ceiling, it is necessary to provide a large opening in the ceiling, which requires the drilling operation of the opening and the reinforcing operation of the opening, which takes time and effort. In addition, the airtightness is also reduced by providing a large opening in the ceiling.

  Therefore, a direct ceiling type down ceiling light has been proposed as a lighting device that does not need to have a large opening in the ceiling (Patent Document 1).

  For example, the conventional direct ceiling type down ceiling light includes an appliance body directly attached to the ceiling, a light source housed in the appliance body, and power for receiving commercial AC power to cause the light source to emit light. And a lighting device to generate.

JP, 2015-032428, A

  Since the fixture body is embedded in the ceiling, the ceiling-mounted downlight does not have much presence. On the other hand, in the direct ceiling type down sealing light, the device body is installed on the ceiling surface with the device body not embedded in the ceiling and the front and side portions of the device body being visible to the user. For this reason, the direct ceiling type down ceiling light has a sense of presence for the user as compared with the ceiling inlaid down light.

  In particular, the conventional down-ceiling type down-seal light is not good in appearance because it is thick and gives a heavy impression to the user.

  In addition, if the device body is made small and thin without considering the reduction in size and thickness of the device body, it is not possible to obtain illumination light having a desired brightness and a desired light distribution as a ceiling light.

  The present invention has been made to solve such a problem, and while reducing the thickness of the device body, it reduces the heavy impression due to the presence of the device body, and has the desired brightness and desired as a ceiling light. An object of the present invention is to provide a luminaire and a luminaire which can obtain illumination light having a desired light distribution.

  In order to achieve the above object, one aspect of a luminaire according to the present invention is a luminaire installed on the installation surface of a construction material, which comprises power supplied from a lighting device provided separately from the luminaire. The instrument body includes a light source emitting light and an instrument body accommodating the light source, the instrument body having a mounting base directly attached to the installation surface, and a light transmitting cover covering the light source, the instrument body Assuming that the height is h and the outer diameter of the device body is d, the relational expression 4 ≦ d / h ≦ 9 is satisfied.

  Further, one aspect of a lighting device according to the present invention includes the lighting device described above and the lighting device for supplying power to the light source of the lighting device, and the lighting device is provided separately from the lighting device. There is.

  A lighting fixture and a lighting device capable of reducing heavy impression due to the presence of a fixture body while achieving thinning of the fixture body, and obtaining illumination light having a desired brightness and a desired light distribution as a ceiling light. realizable.

Therefore, the numerical values, shapes, materials, components, arrangement positions and connection forms of the components, and the order of steps (steps) and steps shown in the following embodiments are merely examples and limit the present invention. It is not the main point to do. Therefore, among the components in the following embodiments, components that are not described in the independent claims indicating the highest concept of the present invention are described as optional components.

  Each figure is a schematic view, and is not necessarily strictly illustrated. In the drawings, substantially the same components are denoted by the same reference numerals, and overlapping descriptions may be omitted or simplified.

Embodiment 1
First, the overall configuration of the illumination device 1 according to the first embodiment will be described using FIG. FIG. 1 is a view schematically showing a lighting device 1 according to a first embodiment.

  As shown in FIG. 1, the lighting device 1 includes a lighting fixture 100 and a lighting device 200 that supplies power to the light source 110 of the lighting fixture 100. The lighting fixture 100 and the lighting device 200 are structurally separated and installed at different places.

  The lighting fixture 100 is a lamp in the lighting device 1. Specifically, the lighting fixture 100 is a ceiling light installed on the ceiling 2 of a building such as a house or a store, and emits illumination light downward. In the present embodiment, the lighting fixture 100 is a direct ceiling type down ceiling light directly attached to the ceiling surface 2 a of the ceiling 2. Therefore, the lighting fixture 100 can be installed on the ceiling 2 without providing the large opening hole in the ceiling 2 unlike a ceiling-embedded downlight which needs to provide the large opening hole in the ceiling 2. Specifically, the ceiling 2 is provided with a small diameter through hole 2b only for passing an electric wire. Thereby, the airtightness between the ceiling 2 and the lighting fixture 100 can be secured.

  Thus, since the lighting fixture 100 can be installed on the ceiling 2 in a state of ensuring airtightness, it is installed not only in the room of the building but also under the entrance, the entrance hall, the toilet, the washroom, the bathroom and the laundry room Alternatively, it can be installed on the ceiling of a relatively humid space such as the corridor outside the apartment. In addition, the luminaire 100 is not limited to the case of being installed on the ceiling 2, and may be installed on a construction material other than the ceiling 2. For example, the lighting fixture 100 may be installed on the installation surface (for example, a wall surface) of a structure such as a wall.

  In the present embodiment, the lighting fixture 100 is a flat and thin down-sealing light. As an example, the height of the lighting fixture 100 is 15 mm or less, and the ratio (outside diameter / height) of the outer diameter to the height of the lighting fixture 100 is four or more. The detailed configuration of the lighting fixture 100 will be described later.

  The lighting device 200 is a drive device that drives the light source 110 of the lighting device 100. The light source 110 is driven by the lighting device 200, whereby the light emission state of the light source 110 is controlled.

  Specifically, lighting device 200 has a power supply function of generating power for causing light source 110 of lighting device 100 to emit light. For example, the lighting device 200 includes a housing, and a power supply terminal block and a power supply circuit disposed in the housing. The power supply terminal block receives the AC power from the commercial power supply 3. The power supply circuit includes a circuit board and a plurality of electronic components mounted on the circuit board, and converts alternating current power received by the power supply terminal block into direct current power.

  The lighting device 200 and the commercial power source 3 are connected by a power cable 400 such as a VVF cable. Therefore, AC power of, for example, 100 V AC flows through the power supply cable 400. The power cable 400 is connected to the power terminal block of the lighting device 200. The direct current power generated by the lighting device 200 is supplied to the light source 110 of the lighting fixture 100. Thereby, the light source 110 emits light and illumination light is emitted from the lighting fixture 100. As described above, the lighting fixture 100 (light source 110) is turned on or off according to the presence or absence of the DC power supplied from the lighting device 200. That is, the lighting device 200 can perform switching control of the lighting state (ON) and the lighting-off state (OFF) of the lighting device 100 as one of the control of the lighting state of the lighting device 100.

  Further, in the present embodiment, lighting device 200 not only performs switching control of lighting on / off of lighting device 100 (light source 110), but also performs dimming control for controlling the brightness of lighting device 100 (light source 110). May be That is, the lighting device 200 may perform light adjustment control of the lighting device 100 as one of control of the light emission state of the lighting device 100. Specifically, the lighting device 200 has a phase control type dimming control function. In this case, the lighting device 200 is provided with a light adjustment control circuit, and the brightness can be adjusted by, for example, cutting a part of the AC power waveform at a predetermined timing using a triac or the like.

  The lighting device 200 not only has a function of performing light adjustment control, but may have a function of performing color adjustment control when the light source 110 corresponds to the color adjustment control. Thereby, the color adjustment control of the light source 110 can be performed. For example, the color temperature of the light emitted by the light source 110 can be changed.

  The lighting device 200 is separated from the lighting fixture 100. That is, the lighting device 200 is not housed in the lighting fixture 100, but is disposed outside the lighting fixture 100. That is, the lighting fixture 100 is a non-power supply built-in type.

  In the present embodiment, lighting device 200 is installed in the vicinity of wall switch 4. Specifically, lighting device 200 is installed in the space area between the inner wall foundation material and the outer wall foundation material on the back side of wall switch 4. That is, the lighting device 200 is hidden in the wall, and the user can not visually recognize the lighting device 200. The lighting device 200 can be stored in the wall using the opening of the wall switch 4. The lighting device 200 may be installed in the wall together with the wall switch 4 when the wall switch 4 is installed, or the wall switch 4 may be removed and installed in the wall after installation. .

  The wall switch 4 is a lighting switch provided on the wall, and controls the light emission state of the lighting fixture 100. The wall switch 4 is, for example, an on / off switch for performing switching control between the lighting state and the extinguishing state of the lighting device 100. As a result, when the user operates the wall switch 4, it is possible to switch between the on state and the off state of the lighting device 100. The wall switch 4 may be provided with a light adjustment knob for adjusting the light of the lighting device 100. Thereby, the user can change the brightness of the lighting fixture 100 by operating the light control knob.

  Furthermore, the lighting device 200 may have a radio wave wireless communication function for controlling the light emission state of the lighting apparatus 100. In this case, for example, the lighting device 200 includes a wireless communication module that receives a wireless signal for controlling the light emission state of the lighting fixture 100. The wireless communication module has a wireless antenna for receiving a wireless signal, and a processing circuit (IC) for processing a wireless signal received by the wireless antenna. The wireless antenna is, for example, a pattern antenna provided on a substrate. The wireless signal received by the wireless antenna is converted into a predetermined control signal (electric signal) by the processing circuit, and is output to the control circuit of the lighting device 200.

  A wireless signal received by the wireless communication module is transmitted from, for example, the wireless remote controller 5 having a wireless transmission function. The wireless remote control 5 may be, for example, a portable portable terminal such as a smartphone possessed by a user, but may be fixed to a wall or the like. The user can control the light emission state of the lighting fixture 100 by operating the wireless remote controller 5. For example, when the user operates the wireless remote controller 5, it is possible to perform on / off control or dimming control of the lighting fixture 100.

  The lighting fixture 100 and the lighting device 200 are connected by a wire inserted through the through hole 2 b of the ceiling 2. In the present embodiment, the lighting fixture 100 and the lighting device 200 are connected by two electric wires of a first electric wire 310 and a second electric wire 320. Thereby, direct-current power generated by the lighting device 200 is supplied to the lighting fixture 100 via the first electric wire 310 and the second electric wire 320. Thus, DC power flows through the first wire 310 and the second wire 320. For this reason, the first electric wire 310 and the second electric wire 320 are not power cables with a large wire diameter such as a VVF cable and are hard to bend but DC wires such as lead wires having a thin wire diameter such as a vinyl wire being thin and flexible. An electric wire can be used. In the present embodiment, the first electric wire 310 and the second electric wire 320 are flat cables.

  The first electric wire 310 is drawn out of the lighting apparatus 100. The first electric wire 310 drawn from the lighting fixture 100 is inserted into the through hole 2 b of the ceiling 2. In the present embodiment, the first electric wire 310 is drawn from the light source 110, and one end of the first electric wire 310 is connected to the light source 110. Further, a first socket 311 is provided at the other end of the first electric wire 310. The first socket 311 is a male or female connector terminal.

  The second electric wire 320 is drawn out of the lighting device 200. One end of the second electric wire 320 is connected to the output terminal of the circuit board of the lighting device 200. Further, at the other end of the second electric wire 320, a second socket 321 is provided. The second socket 321 is a female or male connector terminal.

  The light source 110 of the lighting fixture 100 and the lighting device 200 are electrically connected by connecting the first socket 311 of the first electric wire 310 and the second socket 321 of the second electric wire 320. The first socket 311 and the second socket 321 have a structure in which they are coupled by fitting. For example, when the first socket 311 has a male structure, the second socket 321 has a female structure, and conversely, when the first socket 311 has a female structure, the second socket 321 is male. It has a type structure. Further, in the present embodiment, the first socket 311 and the second socket 321 are connected by a ceiling and a back.

  Next, the specific configuration of the lighting fixture 100 will be described using FIGS. 2 to 4 with reference to FIG. 1. FIG. 2 is a perspective view of the lighting fixture 100 used for the lighting device 1 according to the first embodiment. FIG. 3 is an exploded view of the lighting fixture 100. FIG. 4 is a cross-sectional view of the lighting fixture 100.

  As shown in FIGS. 2 to 4, the lighting fixture 100 includes a light source 110 and a fixture body 120 that houses the light source 110. In the present embodiment, lighting fixture 100 further includes reflecting plate 130 housed in fixture body 120.

  As described above, the lighting fixture 100 is a direct ceiling type down ceiling light. Therefore, as shown in FIG. 1, the whole lighting fixture 100 is exposed from the ceiling surface 2a. Thereby, the instrument main body 120, the light source 110, and the reflecting plate 130 are located on the floor side from the ceiling surface 2a.

  The light source 110 is a light source module that emits light by the power supplied from the lighting device 200, and emits white light as illumination light, for example. In the present embodiment, the light source 110 is an LED light source (LED module) configured of an LED. As an example, as shown in FIG. 3 and FIG. 4, the light source 110 includes a substrate 111 and a light emitting element 112 disposed on the substrate 111.

  The substrate 111 is a mounting substrate for mounting the light emitting element 112. Although not shown, metal wiring is formed on the mounting surface of the substrate 111. DC power is supplied to the light emitting element 112 by the metal wiring. As the substrate 111, a metal base substrate, a ceramic substrate, a resin substrate or the like is used. The substrate 111 is a rigid substrate, but may be a flexible substrate.

  A plurality of light emitting elements 112 are mounted on the substrate 111. Although twelve light emitting elements 112 are mounted in this embodiment, the number of light emitting elements 112 mounted is not limited to this, and may be six or one. It may be 12 or more.

  The light emitting element 112 in the present embodiment is a surface mount device (SMD) type LED element packaged individually, and includes a container (package), an LED chip mounted in the container, and an LED chip. And a sealing member for sealing the

  The LED chip is an example of a semiconductor light emitting element that emits light by a predetermined direct current power, and is a bare chip that emits monochromatic visible light. The LED chip is, for example, a blue LED chip that emits blue light when energized.

  The sealing member is a translucent insulating resin material such as silicone resin. The sealing member in the present embodiment includes a phosphor as a wavelength conversion material that converts the wavelength of light from the LED chip. That is, the sealing member is a phosphor-containing resin in which a fluorescent material is contained in a translucent resin, and wavelength-converts (color-converts) light from the LED chip into a predetermined wavelength. The sealing member is filled in the recess of the container.

  As the sealing member, for example, when the LED chip is a blue LED chip, a phosphor-containing resin in which yellow phosphor particles of YAG (yttrium aluminum garnet) type are dispersed in silicone resin in order to obtain white light It can be used. Thereby, since the yellow phosphor particles are excited by the blue light of the blue LED chip to emit yellow light, from the sealing member, the yellow light from the yellow phosphor particles and the blue light from the blue LED chip are synthesized. White light is emitted as light. In addition, a light diffusing material such as silica, a filler, and the like may be dispersed in the sealing member.

  In the present embodiment, the light source 110 is an SMD type LED module configured by an SMD type LED element, but the present invention is not limited to this. For example, as in the light source 110A shown in FIG. 5, a COB (Chip On Board) type LED module may be used, in which a plurality of LED chips (bare chips) are directly mounted on the substrate 111 as LED elements. In this case, as shown in FIG. 5, all the LED chips may be collectively sealed by the sealing member containing the wavelength conversion material, but the LED chips are sealed line by line by the linear sealing member. Alternatively, the LED chips may be individually sealed one by one by a hemispherical sealing member.

  The fixture body 120 housing the light source 110 is an outer casing of the lighting fixture 100. That is, the external size of the lighting apparatus 100 is the external size of the apparatus body 120. Specifically, the instrument body 120 has a flat and thin outer shape.

  As one example, the height of the instrument body 120 is 15 mm or less. The lower limit of the height of the tool body 120 is not particularly limited, but the height of the tool body 120 may be 4 mm or more in consideration of the arrangement space of the light source 110 and the like.

  In addition, the outer diameter of the tool body 120 may be 60 mm or more and 135 mm or less in consideration of the light distribution of the lighting device 100. In the present embodiment, the plan view shape of the tool body 120 is circular. Therefore, it is preferable that the outer diameter (diameter) of the tool main body 120 be not less than φ60 mm and not more than φ135 mm. When the outer diameter of the fixture body 120 exceeds φ135 mm, light distribution of the lighting device 100 becomes difficult and a heavy impression is given if the height of the lighting device 100 is 15 mm or less. In addition, although the planar view shape of the instrument main body 120 may be not only circular but a rectangle etc., the outer diameter of the instrument main body 120 turns into a largest outer diameter in this case. For example, when the planar view shape of the tool main body 120 is a square, the outer diameter of the tool main body 120 becomes the length of the diagonal of a square.

  Taking the above into consideration, in the lighting apparatus 100 according to the present embodiment, as shown in FIG. 4, when the height of the apparatus body 120 is h and the outer diameter of the apparatus body 120 is d, 4 ≦ d / h ≦ It is good to satisfy the equation of 9.

  As shown in FIGS. 3 and 4, the tool body 120 includes a mounting base 121, a light transmitting cover 122, and a frame 123. In the present embodiment, an outer cover is configured by the light transmitting cover 122 and the frame 123. The mounting base 121 is covered with the outer cover.

  The mounting base 121 is a mounting member for mounting the lighting fixture 100 on the ceiling 2. The mounting base 121 is directly attached to the ceiling surface 2a. In the present embodiment, the mounting base 121 is a plate-like mounting plate, and the mounting base 121 is mounted on the ceiling 2 such that the outer surface faces the ceiling surface 2 a. Specifically, the outer surface of the mounting base 121 is in contact with the ceiling surface 2a.

  The mounting base 121 is made of, for example, a metal plate such as a steel plate or an aluminum plate. In this case, the mounting base 121 may be entirely or partially formed into a predetermined shape by pressing. The mounting base 121 is not limited to a metal plate, and may be made of die-cast aluminum or the like. The thickness of the mounting base 121 may be 1 mm or less.

  The mounting base 121 is provided with a pair of opening holes 121 a. The pair of opening holes 121a is a mounting hole for mounting the mounting base 121 to the ceiling 2, and a fastening member such as a screw or a bolt is inserted through the pair of opening holes 121a. For example, the mounting base 121 can be fixed to the ceiling 2 by inserting a screw into each of the pair of opening holes 121 a and screwing the screw into the ceiling 2.

  Further, the mounting base 121 is provided with an opening hole 121 b. The opening hole 121 b is a wire hole for drawing out the first wire 310 connected to the light source 110 to the outside of the instrument body 120.

  The translucent cover 122 is a translucent cover member that covers the light source 110. In the present embodiment, the light transmitting cover 122 covers the entire reflection plate 130 on which the light source 110 is mounted. The distance between the reflection plate 130 and the light transmission cover 122 is 10 mm or less.

  The translucent cover 122 is made of a translucent resin such as acrylic resin or polycarbonate resin, or a translucent material such as glass. In the present embodiment, the light transmission cover 122 is a diffusion cover having light diffusivity (light scattering property). In this case, by making the light transmitting cover 122 milky white, the light transmitting cover 122 can have light diffusivity. Specifically, light diffusion properties may be imparted to the light transmission cover 122 by dispersing light diffusion particles inside the light transmission cover 122, or milky white light diffusion to the inner surface or the outer surface of the light transmission cover 122. The light-transmissive cover 122 may have light diffusivity by forming a film. Alternatively, the light transmitting cover 122 may have light diffusivity by forming a plurality of light diffusing dots or a plurality of minute irregularities (shrinking) on the surface of the light transmitting cover 122. The light transmission cover 122 is not limited to the diffusion cover, but may be a transparent cover.

  The translucent cover 122 is a translucent panel having a constant thickness. The thickness of the light transmitting cover 122 may be 2 mm or less. Further, in the present embodiment, the light transmission cover 122 is configured in a curved shape so that the central portion slightly protrudes downward, but the present invention is not limited to this. For example, the light transmission cover 122 may be configured in a flat plate shape. Moreover, although the planar view shape of the light transmission cover 122 is circular, it does not restrict to this. The translucent cover 122 configured in this manner is attached to the frame 123 so as to close the floor side opening of the frame 123.

  The frame 123 is a cylindrical frame member. In the present embodiment, the frame body 123 has a flat cylindrical shape. The frame 123 is made of, for example, a resin material, but is not limited to this, and may be made of a metal material.

  The reflecting plate 130 is a reflecting member that reflects the light emitted by the light source 110. The reflecting plate 130 is disposed between the mounting base 121 and the light transmitting cover 122. The reflecting plate 130 is made of, for example, a metal material, but may be made of a resin material. In the present embodiment, the reflection plate 130 is formed by pressing a metal plate such as a steel plate or an aluminum plate. The thickness of the reflective plate 130 may be 2 mm or less. A white paint film or a metal film may be formed on the surface of the reflection plate 130.

  In the present embodiment, the reflecting plate 130 is a light source support base that supports the light source 110. By disposing the light source 110 on the reflection plate 130, the heat generated by the light source 110 can be dissipated to the reflection plate 130. That is, the reflecting plate 130 functions as a heat sink of the light source 110.

  Specifically, the reflecting plate 130 is supported by the mounting portion 131 on which the light source 110 is mounted, the inclined portion 132 surrounding the mounting portion 131 and inclined with respect to the mounting portion 131, and the mounting base 121. And a supporting portion 133.

  The placement unit 131 is provided at a position facing the central portion of the light transmission cover 122. Therefore, the light source 110 mounted on the mounting portion 131 is disposed at a position facing the central portion of the light transmitting cover 122. In the present embodiment, the placement unit 131 has a planar circular shape. The surface of the placement unit 131 is a placement surface on which the light source 110 is placed. The light source 110 placed on the placement unit 131 is positioned between the light transmitting cover 122 and the placement unit 131 of the reflection plate 130. The light source 110 placed on the placement unit 131 is fixed to the placement unit 131 by, for example, a holder or an adhesive. In addition, a heat conduction sheet may be inserted between the light source 110 and the placement unit 131.

  The inclined portion 132 is in the shape of a flat mortar, and is configured such that the opening diameter gradually increases with distance from the light source 110. The surface of the inclined portion 132 is a reflective surface that reflects the light emitted from the light source 110. The inclined portion 132 is disposed at a position facing the peripheral portion, which is a region outside the central portion of the light transmitting cover 122. Thereby, even if the light source 110 is disposed at a position facing the central portion of the light transmission cover 122, the light emitted from the light source 110 can be reflected by the inclined portion 132 to the peripheral portion of the light transmission cover 122. The light emitted from the light source 110 can be spread over the entire area of the light transmission cover 122. Therefore, the entire surface of the light transmitting cover 122 can be surface-emitted.

  The support portion 133 is provided at the peripheral portion of the inclined portion 132. By providing the support portion 133, a space for drawing and storing the first electric wire 310 can be provided between the inclined portion 132 and the mounting base 121. In the present embodiment, the support portion 133 has a flat cylindrical shape and is provided on the entire circumference of the inclined portion 132, but may be partially provided on a part of the inclined portion 132.

  The support portion 133 is also a fixing portion for connecting and fixing the reflecting plate 130 to the mounting base 121. By fixing the support portion 133 to the mounting base 121, the reflecting plate 130 can be fixed to the mounting base 121. The support portion 133 and the mounting base 121 can be fixed by, for example, a screw or a hooking structure.

  The reflection plate 130 is provided with a through hole 130 a for passing the first electric wire 310. As shown in FIG. 4, the first electric wire 310 connected to the substrate 111 of the light source 110 is drawn out to the space area between the reflecting plate 130 and the mounting base 121 through the through hole 130 a, and the mounting base It is drawn out of the mounting base 121 from the opening hole 121 b of 121.

  In the present embodiment, the through hole 130 a is not provided at a position facing the opening hole 121 b. Thereby, tension stop of the 1st electric wire 310 can be performed. The through holes 130a may be provided at positions facing the opening holes 121b. Thereby, it can suppress that the 1st electric wire 310 is drawn around in the instrument main body 120 uselessly. That is, the portion of the first electric wire 310 in the instrument body 120 can be reduced as much as possible.

  When the lighting fixture 100 configured in this manner is installed on the ceiling 2, first, the mounting base 121 is fixed to the ceiling 2 by a screw or the like. Next, the reflecting plate 130 on which the light source 110 is mounted is fixed to the mounting base 121. At this time, the reflecting plate 130 and the mounting base 121 may be fixed by screws, but the mounting base 121 is provided with a pair of leaf spring structures and the leaf spring structure is locked to the side surface of the reflecting plate 130. The reflecting plate 130 and the mounting base 121 may be fixed by the hooking structure by providing the recessed portion. Thereafter, the outer cover formed of the light transmitting cover 122 and the frame 123 is fixed to the reflecting plate 130 or the mounting base 121.

  Moreover, as shown in FIG. 6, the lighting device 1 may have a plurality of lighting fixtures 100. Each of the plurality of lighting fixtures 100 is directly attached to the ceiling surface 2 a of the ceiling 2 in the same manner as the lighting fixture 100 shown in FIG. 1. The respective luminaires 100 are the same in configuration, and the same ones can be used. That is, each lighting fixture 100 includes the light source 110, the fixture body 120, and the reflecting plate 130.

  The lighting conditions of the plurality of lighting devices 100 are simultaneously controlled. For example, when the user operates the wall switch 4 or the wireless remote controller 5, lighting on / off control or dimming control of the plurality of lighting fixtures 100 can be performed simultaneously.

  In the present embodiment, a plurality of lighting devices 200 are arranged in accordance with the number of lighting fixtures 100. That is, the plurality of lighting devices 100 and the plurality of lighting devices 200 correspond to each other one by one, and the lighting devices 100 and the lighting devices 200 are installed in the same number. In FIG. 6, three lighting fixtures 100 and three lighting devices 200 are installed. Each lighting device 200 has the same configuration as each other, and the same one can be used.

  A plurality of lighting fixtures 100 are installed at any places where light is required. For example, a plurality of lighting fixtures 100 are installed at predetermined intervals. On the other hand, the plurality of lighting devices 200 are all installed in one place. Specifically, the plurality of lighting devices 200 are installed adjacent to the wall switch 4.

  Each of the plurality of lighting fixtures 100 and each of the plurality of lighting devices 200 are connected by an electric wire. Specifically, the lighting fixture 100 and the lighting device 200 which are in a corresponding relationship are connected by the first electric wire 310 and the second electric wire 320, as in FIG.

  Further, the plurality of lighting devices 200 are connected by the third electric wire 330. Specifically, as shown in FIG. 7, two adjacent lighting devices 200 are connected by the third electric wire 330. The third electric wire 330 is an AC feed wiring for sending AC power from one of the two adjacent lighting devices 200 to the other. That is, in the two adjacent lighting devices 200, the AC power received by one lighting device 200 is supplied to the other lighting device 200 via the third electric wire 330. As an example, the AC power from the commercial power source 3 is sequentially supplied to the adjacent lighting device 200 via the third electric wire 330. In addition, although the 3rd electric wire 330 is a flat cable, it does not restrict to this.

  Each lighting device 200 also has a power supply terminal block 210. Electric wires (power cable 400 and third electric wire 330) through which AC power flows are inserted into the power supply terminal block 210. In each lighting device 200, AC power is received via the electric wire inserted into the power supply terminal block 210. The AC power received by the power supply terminal block 210 is supplied to the power supply circuit housed in the housing 220.

  The power supply terminal block 210 includes a pair of first terminal portions 211 to which alternating current power is input, and a pair of second terminal portions 212 that output the alternating current power. In the present embodiment, power supply terminal block 210 is incorporated in housing 220 in a state where a part thereof is exposed from housing 220, and first terminal portion 211 and second terminal portion 212 are provided in the exposed portion. ing.

  The power cable 400 is inserted into the first terminal portion 211 of the power terminal block 210 and the second terminal portion 212 is connected to one of the plurality of lighting devices 200 (the lighting device 200 on the left side in FIG. 7). One end of the electric wire 330 is inserted. In addition, the other end of the third electric wire 330 is inserted into the first terminal portion 211 of the power supply terminal block 210 of another lighting device 200 (the lighting device 200 in the middle in FIG. 7).

  The remaining lighting devices 200 are similarly sequentially connected by the third electric wires 330. Specifically, one end of the third electric wire 330 is inserted into the first terminal portion 211 of the power supply terminal block 210 of one lighting device 200 of two adjacent lighting devices 200, and the power supply of the other lighting device 200 The other end of the third electric wire 330 is inserted into the second terminal portion 212 of the terminal block 210.

  Next, the operation and effect of the illumination device 1 according to the present embodiment will be described including the background of the present invention.

  In recent years, there has been a demand for downsizing and thinning of lighting fixtures, but the conventional ceiling-mounted ceiling light incorporates a power supply terminal block and a lighting device, so the storage space for the power terminal block and the lighting device In view of the above, it is difficult to miniaturize and thin the device body.

  Moreover, since the power cable such as the VVF cable connected to the power terminal block is relatively thick and difficult to bend, the storage space of the power cable in the main body of the device can be reduced by reducing the size of the device body for housing the power terminal block and the lighting device. Becomes narrower. For this reason, at the time of installation of a lighting fixture, a power supply cable is crimped and drawn around within the fixture body. As a result, the mounting plate installed on the ceiling surface may float from the ceiling due to the bending reaction force of the power cable, and a gap may be generated between the ceiling and the mounting plate during construction.

  Also, as shown in FIG. 8, when simultaneously controlling the light emission states of a plurality of lighting fixtures 1100 installed on the ceiling 2, conventionally, lighting is stored in each lighting fixture 1100 in two adjacent lighting fixtures 1100. The devices 1200 (power supply terminal blocks) are connected to each other by a power supply cable 1330 for sending and wiring. That is, the AC power from the commercial power source 3 is sequentially sent to the adjacent lighting fixture 1100 by the power cable 1330. For this reason, in addition to the electric wire cable 400, the power supply cable 1330 for feed wiring is drawn around in the instrument body. As a result, the space in the fixture body of the lighting fixture 1100 is further narrowed and the mounting plate is more easily lifted from the ceiling.

  Therefore, a ceiling mounted ceiling light not incorporating a power supply terminal block and a lighting device has been considered. Thereby, thickness reduction and size reduction of an instrument main body can be achieved easily.

  However, unlike the ceiling-mounted downlight in which the fixture body is embedded in the ceiling, the fixture body is on the ceiling surface with the front and side portions of the fixture body visible to the user, unlike the ceiling-mounted down ceiling light. Because it is installed, it makes the user feel a sense of presence.

  For this reason, even if the tool body is simply thinned, a heavy impression given to the user remains without reducing the presence of the tool body very much. In particular, the conventional direct ceiling-mounted down ceiling light incorporating the power supply terminal block and the lighting device has a poor appearance due to its large thickness (high height) and gives the user a fairly heavy impression.

  Moreover, it is possible to obtain illumination light having a desired brightness and a desired light distribution as a ceiling light simply by reducing the size and thickness of the device body without considering the reduction in size and thickness of the device body. It will be gone.

  Therefore, as a result of intensive investigations by the inventors of the present invention, after the lighting device has been placed separately from the lighting fixture, the ratio of the height to the outside diameter (outside diameter / height) of the lighting fixture in the fixture body is further appropriate. By setting the range, it is possible to reduce the heavy impression due to the presence of the device body while achieving thinning of the device body, and to obtain illumination light of a desired brightness and a desired light distribution as a ceiling light. Found out.

  Specifically, in the lighting device 1 in the present embodiment, the lighting fixture 100 having the light source 110 and the lighting device 200 for controlling the light emission state of the light source 110 are separately provided separately. As a result, since the lighting device 200 having a large occupied area in the lighting device 1 is disposed separately from the lighting fixture 100, the fixture main body 120 housing the light source 110 can be easily thinned.

  And, in the lighting apparatus 100 according to the present embodiment, as shown in FIG. 4, the height (h) and the outer diameter (d) of the apparatus main body 120 satisfy the relational expression 4 ≦ d / h ≦ 9. Is configured. Thereby, the lighting fixture 100 which can obtain illumination light of desired brightness and desired light distribution as a ceiling light can be realized while reducing heavy impression due to the presence of the fixture body.

  In this case, the height h of the tool body 120 may be 15 mm or less. As described above, by setting the height h of the device body 120 to 15 mm or less, the thin and small lighting device 100 capable of giving a clear impression by further reducing the heavy impression due to the presence of the device body is provided. It can be realized.

  As mentioned above, according to the illuminating device 1 which concerns on this Embodiment, while achieving thickness reduction of the instrument main body 120, the heavy impression by the presence of the instrument main body 120 is reduced, and desired brightness and a desired as a ceiling light The lighting fixture 100 which can obtain the illumination light which has a light distribution can be implement | achieved.

  Moreover, the lighting fixture 100 in this Embodiment is further provided with the reflecting plate 130 which reflects the light which the light source 110 emits. The reflecting plate 130 has a mounting portion 131 on which the light source 110 is mounted, and an inclined portion 132 surrounding the mounting portion 131 and inclined with respect to the mounting portion 131.

  With this configuration, even with the thin and flat instrument body 120, the entire surface of the light transmitting cover 122 can be easily surface-emitted. Thereby, although it is thin apparatus main body 120, desired brightness and desired light distribution can be easily realized as a ceiling light.

  In this case, the distance between the reflecting plate 130 and the light transmitting cover 122 may be 10 mm or less. Further, the thickness of the reflection plate 130 is 2 mm or less, the thickness of the mounting base 121 is 1 mm or less, and the thickness of the light transmission cover 122 is 2 mm or less.

  With this configuration, even when the reflection plate 130 is used, it is possible to easily realize a thin and small instrument body 120 having a height h of 15 mm or less.

  Further, in the present embodiment, the light source 110 and the lighting device 200 are electrically connected by connecting the first socket 311 and the second socket 321. Specifically, the first socket 311 is provided in the first electric wire 310 for direct current drawn from the light source 110.

  With this configuration, wire connection between the light source 110 and the lighting device 200 (that is, connection between the first socket 311 and the second socket 321) can be performed outside the appliance body 120. Thereby, construction of the lighting fixture 100 can be performed easily.

  Moreover, in the present embodiment, the first electric wire 310 is a flat cable. Further, the ceiling 2 is provided with a through hole 2 b through which the first electric wire 310 is inserted.

  With this configuration, the opening diameter of the through hole 2b of the ceiling 2 can be reduced, so the airtightness between the ceiling 2 and the lighting fixture 100 can be improved. Moreover, according to this configuration, the connection work between the first socket 311 and the second socket 321 can be performed on the ceiling.

  Further, in the present embodiment, the second socket 321 is provided in the second electric wire 320 for direct current drawn from the lighting device 200.

  With this configuration, the connection work between the first electric wire 310 drawn from the light source 110 and the second electric wire 320 drawn from the lighting device 200 can be easily performed. Thereby, installation of the illuminating device 1 can be performed easily.

  The second socket 321 may be mounted on the circuit board of the lighting device 200. In this case, without using the second electric wire 320, the first socket 311 of the first electric wire 310 drawn from the light source 110 can be directly inserted into the second socket 321 mounted on the circuit board of the lighting device 200. .

  In addition, the lighting device 1 in the present embodiment is configured by the lighting fixture 100 and the lighting device 200. And the lighting device 200 is separately installed with the lighting fixture 100 as mentioned above.

  Thereby, while achieving thinning of the device body 120, it is possible to reduce heavy impression due to the presence of the device body 120 and obtain illumination light having a desired brightness and a desired light distribution as a ceiling light. The device 1 can be realized.

  Further, in the present embodiment, lighting device 200 has a phase control type light adjustment control function.

  As a result, it is possible to realize a thin lighting fixture 100 while providing the lighting device 1 with a light control function.

  Further, in the present embodiment, lighting device 200 has a radio wave wireless communication function for controlling the light emission state of lighting device 100.

  Thereby, the light emission state of the lighting fixture 100 can be controlled by radio wave type wireless communication. For example, when the lighting device 200 receives a wireless signal from a portable terminal carried by the user, lighting on / off control of the lighting fixture 100 or dimming control can be performed.

  In the present embodiment, lighting device 200 is installed in the vicinity of wall switch 4 that controls the light emission state of lighting fixture 100. Specifically, the lighting device 200 is attached adjacent to the wall switch 4.

  According to this configuration, since lighting device 200 can be inserted into the wall from the opening of the wall provided for installing wall switch 4, construction of lighting device 200 can be easily performed. In this case, the external size of the lighting device 200 may be such that the opening of the wall on which the wall switch 4 is installed can be inserted.

  Moreover, since there are few obstacles blocking the wireless signal (radio wave) in the vicinity of the wall switch 4 and the wireless signal is less likely to be blocked, the lighting device 200 is a wall switch when the lighting device 200 has the radio wave type wireless communication function. By installing in the vicinity of 4, the wireless signal can be received with high sensitivity from the portable terminal or the like of the user.

  Moreover, as shown in FIG. 6, when arrange | positioning multiple lighting fixtures 100, multiple lighting devices 200 are also arrange | positioned. In this case, the plurality of lighting devices 100 and the plurality of lighting devices 200 correspond to each other one by one, and each of the plurality of lighting devices 100 and each of the plurality of lighting devices 200 are connected by electric wires.

  With this configuration, each lighting device 200 can be connected to each lighting device 100. Further, the number of connections from the commercial power source 3 to the lighting apparatus 100 can be reduced. Thereby, construction of the illuminating device 1 can be performed more easily.

  Further, as shown in FIG. 7, in the present embodiment, each of the plurality of lighting devices 200 has a power supply terminal block 210. The power supply terminal block 210 includes a pair of first terminal portions 211 to which alternating current power is input, and a pair of second terminal portions 212 that output the alternating current power.

  With this configuration, AC power can be sequentially sent to the plurality of lighting devices 200 by connecting the power supply terminal blocks 210 of the respective lighting devices 200 with the third electric wire 330.

  Further, in the present embodiment, the plurality of lighting devices 200 are collectively arranged near the wall switch 4.

  By this configuration, the connection work of the third electric wire 330 connecting the plurality of lighting devices 200 can be easily performed.

  In addition, although the through-hole 130a of the reflecting plate 130 was provided in the inclination part 132 in the lighting fixture 100 shown by FIG. 4, it does not restrict to this. For example, as in the lighting fixture 101 shown in FIG. 9, the through hole 130 a of the reflection plate 130 may be provided in the placement unit 131. Thereby, the first electric wire 310 drawn from the light source 110 can be drawn to the back side of the reflecting plate 130 through the through hole 130 a of the mounting portion 131. Thereby, it can suppress that the light distribution characteristic of the lighting fixture 100 degrades by the shadow of the 1st electric wire 310. FIG. That is, in the configuration of the lighting fixture 100 shown in FIG. 4, since the first electric wire 310 exists in the inclined portion 132 of the reflecting plate 130, the light distribution characteristic of the lighting fixture 100 is degraded by the shadow of the first electric wire 310. Although there is a fear, in the luminaire 101 shown in FIG. 9, since the first electric wire 310 is not present in the inclined portion 132, it is suppressed that the light distribution characteristic of the luminaire 100 is deteriorated due to the shadow of the first electric wire 310. it can. In this case, the opening hole 121b of the mounting base 121 is provided at a position facing the through hole 130a as shown in FIG. 9 in order to minimize the amount of routing of the first electric wire 310 in the instrument body 120. Good to have.

  Moreover, in the lighting fixture 100 shown by FIG. 4, although the clearance gap existed between the mounting part 131 of the reflecting plate 130, and the attachment base 121, it is reflected like the lighting fixture 102 shown by FIG. The mounting portion 131 of the plate 130 may be brought into contact with the mounting base 121 to eliminate the gap between the mounting portion 131 and the mounting base 121. Specifically, in FIG. 10, the ceiling-side surface of the mounting portion 131 of the reflection plate 130 and the floor-side surface of the mounting base 121 are in surface contact. With this configuration, the thickness of the tool body 120 can be further reduced, and the heat generated by the light source 110 can be efficiently conducted to the mounting base 121 via the mounting portion 131 and dissipated.
