Description

  The present invention relates to a lighting fixture including a plurality of substrate modules having an antenna function.

  Conventionally, for example, when a plurality of lighting fixtures in one room are controlled in a batch using a light controller, the controller of the light controller that receives power supply controls the plurality of lighting fixtures. (For example, patent document 1). Separately from the light controller, a power supply that can be individually controlled is supplied to the lighting fixture side, and an individual control signal is sent wirelessly from the light controller to control the power supply to each lighting fixture, and dimming and toning are performed. Control is proposed (for example, refer to Patent Documents 1 and 2).

  In the conventional technology as described above, since the load capacity that can be handled is limited due to power concentration, temperature rise control, etc., the number of lighting fixtures is easily limited, and wiring is complicated. A situation can arise. Therefore, it is conceivable that each lighting fixture receives a control signal from the light controller and performs light control and color matching of the lighting fixture. However, recent housing structures provide a large room with as few pillars as possible, so it is necessary to install lighting fixtures on the ceiling and walls. However, in order to provide an energy-saving and comfortable environment, heat insulation including metal wool such as glass wool with aluminum is laid on the walls of the house, etc., so that the radio does not reach the lighting equipment installed on the walls etc. There was a problem.

  The present invention provides a lighting fixture that can accurately receive a light control or color control signal transmitted from a light controller or the like.

  The lighting fixture of the present invention is a lighting fixture obtained by connecting a plurality of substrate modules in series, and each of the plurality of substrate modules includes a substrate and a plurality of semiconductors provided on the first surface of the substrate. A light emitting element and a conductor pattern provided on the first surface, wherein at least one conductor pattern of one substrate module functions as an antenna capable of receiving a wireless communication wave from the outside, The conductor pattern of other board modules other than the board module does not function as an antenna.

  According to the lighting apparatus of the present invention, since the conductor pattern is provided on the first surface of the same substrate as the surface from which the light of the semiconductor light emitting element is emitted, it is possible to directly receive a radio communication wave, which is reliable. Light control of the luminaire is possible. That is, the problem that the radio signal does not reach is solved because the conductor pattern inevitably protrudes from the building structure to the indoor space side. In addition, it is possible to prevent a failure that a wireless signal does not reach by a heat insulating material containing metal on a wall or the like. And since the conductor pattern in one board | substrate module functions as an antenna in the whole lighting fixture, the frequency design is made possible easily.

  The substrate 21 is preferably a flexible substrate.

  FIG. 1 is a conceptual diagram of a lighting device 1 according to an embodiment, and FIG. 2 is an exploded perspective view of a lighting fixture 10. The lighting device 1 and the lighting fixture 10 will be described with reference to FIGS. 1 and 2.

  The lighting device 1 is obtained by electrically connecting a plurality of lighting fixtures 10 via a cable K as shown in FIG. As shown in FIG. 2, the luminaire 10 has a substantially quadrangular prism-shaped appearance, and includes a body 11 having an open upper surface and both sides and having a substantially U-shaped cross section. Cover 12 is fixed so as to cover, and first connector 13 and second connector 14 are fixed to both sides of body 11. A power source unit 15 and a plurality of board modules 20 (20A, 20B) are housed in a room formed by fixing the cover 12 to the body 11.

  The body 11 is a molded product made of synthetic resin, metal, or the like, and the cover 12 is molded from a translucent resin such as acrylic or polycarbonate, and milky white or light that diffuses light from a semiconductor light emitting element 22 described later in all directions. A lens such as a prism that controls the direction is applied.

  Each of the plurality of substrate modules 20 (20A, 20B) includes a single substrate 21, and is a flexible substrate made of polyethylene terephthalate, polyimide, polyamide resin or the like, or a rigid substrate made of glass / epoxy resin or the like. It is. On the first surface 21a of the substrate 21 facing the cover 12, a semiconductor light emitting element 22 made of, for example, an LED (Light Emitting Diode) or the like and functioning as a light source of the lighting device 1 is formed on the first surface 21a. A plurality of power supply wiring patterns (not shown) are mounted. Each of the substrate modules 20 (20A, 20B) is provided with a conductor pattern 23 (23A, 23B). As will be described later, in this embodiment, the conductor pattern 23A of the board module 20A functions as an antenna capable of receiving a radio communication wave from the outside, and the conductor patterns 23B of other board modules 20B do not function as antennas.

  The first surface 21a of the substrate 21 is a surface on the side where the semiconductor light emitting element 22 emits light, and becomes the front side of the lighting device 1 when the lighting device 1 is attached to a ceiling or a wall. That is, when the lighting device 1 is installed on a wall or the like, the receiving surface of the conductor pattern 23 that receives the radio communication wave from the light controller 30 (see FIG. 4) that controls the lighting device 1 (lighting fixture 10) is on the indoor side. It will be in the state of facing. By providing the conductor pattern 23 functioning as an antenna on the first surface 21a of the substrate 21, the conductor pattern 23A can directly receive a transmission signal (radio wave) from the light controller 30 described later without an obstacle.

  Further, the first terminal 25 and the second terminal 26 are mounted on both sides of the first surface 21a of the substrate 21, respectively. The first terminal 25 is provided with a connection terminal 25 a that is electrically connected to the conductor pattern 23, and a plus-side connection terminal 25 b and a minus-side connection terminal 25 c that supply power to the semiconductor light emitting element 22. . On the other hand, the second terminal 26 is provided with a connection terminal 26 a that is not electrically connected to the conductor pattern 23, and a positive connection terminal 26 b and a negative connection terminal 26 c that supply power to the semiconductor light emitting element 22. ing.

  The first terminal 25 is electrically connected to the first connector 13, the second terminal 26 is electrically connected to the second connector 14, and the power supply unit 15 is connected to the first connector via the lead wire L. 13 and the second connector 14 are electrically connected. Both connectors 13 and 14 are fixed to the body 11 with screws 16 or the like. Further, on the first connector 13 side, a lead wire L connected from the power supply unit 15 to the first terminal 25 is provided, and the connection terminal 25a, the plus side connection terminal 25b and the minus side connection terminal 25c of the board 21 are electrically connected. Connected. Further, a VVF (Vinyl insulated Vinyl sheathed Flat-type) cable (or a feed line, etc.) K from the commercial power supply AC or another lighting fixture 10 is electrically connected to the connectors 13 and 14 by mechanical fastening or the like. Connected.

  FIG. 3 is a conceptual diagram illustrating an example of the arrangement of the substrate modules 20 in the lighting fixture 10.

  Each board module 20 (20A, 20B) is electrically connected via a cable C. That is, the plus side connection terminal 25b of the first terminal 25 of the board module 20B is connected to the plus side connection terminal 26b of the second terminal 26 of the board module 20A. Further, the minus side connection terminal 25c of the first terminal 25 of the board module 20B is connected to the minus side connection terminal 26c of the second terminal 26 of the board module 20A. As a result, the board module 20A and the board module 20B are connected in series.

  The power supply unit 15 includes a conversion circuit 15 a that receives AC power from the commercial power supply AC, converts it to DC power, and supplies power to the semiconductor light emitting element 22. The power supply unit 15 includes a control unit 15b that controls the brightness of the semiconductor light emitting element 22, and a radio circuit 15c that receives a signal transmitted from the light controller 30 and transmits the signal to the control unit 15b.

  Here, the power supply unit 15 and the first terminal 25 are electrically connected, and the radio circuit 15c of the power supply unit 15 is connected to the conductor pattern 23A of the board module 20A via the connection terminal 25a. Therefore, the conductor pattern 23A of the board module 20A functions as an antenna capable of receiving a wireless communication wave from the outside.

  The conductor pattern 23A of the board module 20A that functions as an antenna is not electrically connected to the connection terminal 26a of the second terminal 26. That is, the conductor pattern 23A that functions as an antenna is connected to the first terminal 25, but is not connected to the second terminal 26 that ensures electrical connection with the other board module 20B. Therefore, the conductor pattern 23B of the board module 20B does not function as an antenna even though it is connected to the connection terminal 25a in the same manner as the conductor pattern 23A of the board module 20A.

  The board module 20A and the board module 20B are the same type of modules, and the size (length) of the lighting fixture 10 can be easily changed by changing the number of board modules 20 to be connected. It is assumed that lighting fixtures 10 of various lengths are required according to the installation site of the lighting device 1, and the number of substrate modules 20 to be connected is arbitrarily changed.

  Under such circumstances, if the conductor pattern 23 is connected to both the first terminal 25 and the second terminal 26, if a plurality of board modules 20 are connected in accordance with the above-described requirements, All of the conductor patterns 23 are connected. This means that the electric circuit length as an antenna assumed by the conductor pattern 23 alone is extended (specifically, the electric circuit length = the length of the conductor pattern 23 × the number of connections).

  Basically, the communication frequency of the light controller that controls the lighting device 1 (lighting fixture 10) by wireless communication is determined in advance. However, if the length of the electric circuit as an antenna changes with the connection of the board module 20 as described above, the frequency band that can be received changes, which makes control by the light controller difficult and extremely inconvenient.

  However, as described above, in this embodiment, even when the board module 20A and the board module 20B are connected, only the conductor pattern 23A of the board module 20A functions as an antenna. Therefore, control of the lighting apparatus 1 (lighting fixture 10) with a predetermined communication frequency is ensured, convenience is improved, and frequency design is facilitated. Although the case where two board modules 20A and 20B are connected has been described in the present embodiment, the effect of the present invention is maintained even when three or more board modules 20 are connected.

  In the above-described embodiment, only one (single) conductor pattern 23A of the board module 20A functions as an antenna. However, it is also possible to configure the conductor pattern 23A by a combination of a plurality of conductor pattern elements that are individually separated for the purpose of giving specific directivity. When an antenna is configured by a combination of a plurality of conductor pattern elements, the type is not limited. Thus, all elements may be physically and electrically connected, but are not limited to such a design. For example, it is possible to use a non-powered element that does not have an electrical connection as seen in the Yagi / Uda antenna.

  Therefore, “one conductor pattern 23A functions as an antenna capable of receiving a radio communication wave from the outside” means that both a single conductor pattern and a conductor pattern composed of a plurality of elements are included.

  By using the same type of module, such as the board module 20A and the board module 20B, mass production of the lighting fixture 10 can be facilitated and the cost can be reduced. The workability can be improved by connecting the substrate modules 20 excluding the connection terminals 25a and 26a.

  Note that the connection terminal 26a of the second terminal 26 may be omitted.

  FIG. 4 is a conceptual diagram showing an example of the relationship between the lighting device 1 (lighting fixture 10) and the light controller 30.

  From the light controller 30, a control signal for performing dimming or color adjustment of each lighting fixture 10 is transmitted to each lighting fixture 10. A radio communication wave is received by the conductor pattern 23 (antenna) provided in the lighting fixture 10, and light control of each lighting fixture 10 is performed. Since the conductor pattern 23 is provided on the first surface 21a of the same substrate 21 as the surface from which the light from the semiconductor light emitting element 22 is emitted, the conductor pattern 23 directly receives a radio communication wave, so that reliable light control of the lighting fixture 10 is possible. It becomes possible. That is, since the conductor pattern 23 inevitably protrudes from the building structure to the indoor space side, the problem that radio does not reach is solved. In addition, it is possible to prevent a failure that radio does not reach by a heat insulating material containing metal on a wall or the like.

  By providing the semiconductor light emitting element 22 and the conductor pattern 23 on the first surface 21 a of the substrate 21, it is possible to effectively use the light without disturbing the light emitted from the semiconductor light emitting element 22.

  The radio wave transmitted from the light controller 30 is a radio wave of a specific low power radio station that does not require a license or notification based on the Radio Law, Bluetooth (registered trademark), UWB (Ultra Wide Band), wireless LAN It is possible to use short-distance wireless communication, such as ad hoc communication that does not require a base station. In addition, in the case of Bluetooth (registered trademark) 4.0 standard, low power consumption BLE (Bluetooth Low Energy) may be used, or a wide area network (4G / LTE or the like) may be used. The light controller 30 may be a fixed type installed on an indoor wall or the like, or a portable terminal such as a smart phone.

  In addition, when the number of the lighting fixtures 10 is large and the installation area is in a wide range, it is assumed that it is difficult for radio waves transmitted from the light controller 30 to reach all the lighting fixtures 10. In such a case, a so-called relay-type wireless communication in which a nearby lighting fixture 10 receives a radio wave from the light controller 30 and the lighting fixture 10 further transmits a radio wave to another lighting fixture 10 is adopted. Also good.

  In the above-described embodiment, the example in which the conductor pattern 23 functions as an antenna capable of receiving a wireless communication wave from the outside has been described. However, it is preferable that the conductor pattern 23 is also provided with a function of transmitting radio waves, and the conductor pattern 23 functions as an antenna capable of transmitting and receiving radio communication waves to the outside and from the outside.

  Although the power supply from the commercial power supply AC is shown in the embodiment of FIG. 4, a DC power supply may be used.

  The first surface 21a, the first terminal 25, the second terminal 26, and the like are referred to as “first” and “second” for easy understanding of the description, but are not limited to terms.

  Although the external shape of the luminaire 10 has been described as a substantially quadrangular prism shape, other shapes such as a circular column and an elliptical column may be used, and the external shape is not limited. Moreover, the lighting fixture 10 can also be comprised in an aspect like a flexible tape light.

  In addition, this invention is not limited to embodiment mentioned above, A deformation | transformation, improvement, etc. are possible suitably. In addition, the material, shape, dimension, numerical value, form, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.
