(Embodiment)
Hereinafter, the illuminating device 1 which concerns on embodiment is demonstrated using FIGS. 1-3. FIG. 1 is a diagram illustrating a configuration of a lighting device 1 according to an embodiment. 2 and 3 are diagrams illustrating an installation example of the lighting device 1 according to the embodiment, in which FIG. 2 is a cross-sectional view and FIG. 3 is a perspective view when viewed from below.

  As shown in FIGS. 1 to 3, the lighting device 1 emits light by a main body 10, a power supply wire 20 that can be drawn from the main body to an arbitrary place, and predetermined power supplied via the power supply wire 20. And a light source unit 30 installed on the power supply wire 20.

  As shown in FIGS. 1 and 2, the main body unit 10 includes a base 11 and a power supply circuit 12. The main body 10 in the present embodiment further includes a circuit case 13 and a support column 14.

  The base 11 is a power reception unit attached to the illumination power supply unit. As shown in FIG. 2, in the present embodiment, the illumination power supply unit is a socket 110 of the luminaire 100 installed at a predetermined location. Therefore, the base 11 is attached to the socket 110 of the lighting fixture 100. The base 11 receives power for causing the light source unit 30 (LED) to emit light from the socket 110 (illumination power supply unit). The lighting fixture 100 shown in FIGS. 2 and 3 is a downlight.

  The base 11 is, for example, a screw-on Edison type (E type) base (E base). Specifically, the base 11 is a base such as E26 type, E17 type, or E16 type. Note that the base 11 is not limited to the E base as long as it has a structure suitable for a predetermined lighting fixture or the like already installed. For example, the base 11 may be a plug-in base or the like.

  Thus, the main body 10 can be easily mounted on the already installed lighting fixture by using the base 11 having a structure suitable for the existing lighting fixture such as the E type. Thereby, the illuminating device using the lighting fixture already installed is realizable.

  The base 11 is supplied with AC power from, for example, a commercial power supply (AC power supply) via a socket 110 (lighting power supply unit). The base 11 in the present embodiment receives AC power through two contact points. The power received by the base 11 is input to the power supply circuit 12 via a lead wire (not shown) or the like.

  The power supply circuit 12 converts the power received by the base 11 into predetermined power. In the present embodiment, the power supply circuit 12 converts the power received by the base 11 into power for causing the light source unit 30 to emit light, and supplies the power to the light source unit 30. For example, the power supply circuit 12 converts AC power supplied from the base 11 into DC power, and supplies the DC power to the light source unit 30 through the power supply wire 20.

  The power supply circuit 12 is a circuit unit including, for example, a circuit board and circuit components mounted on the circuit board. The power supply circuit 12 may be combined with a dimmer circuit, a booster circuit, or the like. The power supply circuit 12 is housed in a circuit case 13 as shown in FIGS.

On the other hand, the opening on the side opposite to the base 11 side (floor side) of the circuit case 13 may be opened, or may be closed with a protective panel or the like as shown in FIG. In the present embodiment, the circuit case 13 is an outer casing, and the outer surface of the circuit case 13 is exposed to the atmosphere.

  The support column 14 functions as a relay power supply unit when supplying power output from the power supply circuit 12 to the power supply wire 20. That is, the power output from the power supply circuit 12 is supplied to the feeder wire 20 via the support 14. For example, a conductive member such as a lead wire is disposed inside the support column 14, whereby the power supply circuit 12 and the power supply wire 20 are electrically connected.

  The support column 14 extends from the circuit case 13. Thereby, the feeding wire 20 can be easily pulled out from the circuit case 13 (main body portion 10). In this Embodiment, the support | pillar 14 is extended from the inside of the circuit case 13 to the exterior of the circuit case 13, as shown in FIGS. Moreover, the support | pillar 14 is extended in the vertically downward direction so that it may protrude from the opening of the instrument main body 120 of the lighting fixture 100, as shown in FIG.2 and FIG.3.

  Moreover, the support | pillar 14 may have the drawing amount adjustment part (not shown) which can adjust the drawing amount of the electric power feeding wire 20. FIG. For example, a cord reel (cable reel) capable of winding or extending the power supply wire 20 can be used as the drawing amount adjustment unit, for example. Thereby, the feed wire 20 can be easily adjusted to an arbitrary length.

  Note that the pull-out amount adjusting unit may be provided in the main body unit 10 other than the column 14 such as the inside of the circuit case 13 instead of the column 14. In this case, it is not necessary to provide the support | pillar 14, and the power supply circuit 12 and the electric power feeding wire 20 may be electrically connected via the drawer | drawing-out adjustment part.

  The power supply wire 20 is a power supply unit for supplying predetermined power from the main body unit 10 to the light source unit 30.

Second feeding wire (second feeding line) 22. Each of the first power supply wire 21 and the second power supply wire 22 includes, for example, a metal wire (core wire) and an insulating coating (resin coating) that covers the metal wire.

  As described above, the power supply wire 20 is configured to be drawn out from the main body 10 to an arbitrary place. In the present embodiment, the feeding wire 20 is drawn from the support column 14. That is, one end of each of the first power supply wire 21 and the second power supply wire 22 is connected to the support column 14. For example, the first power supply wire 21 and the second power supply wire 22 are wound around a pull-out amount adjustment unit (code reel) of the support column 14.

  On the other hand, a fixing member 40 for fixing the pair of power supply wires 20 to a predetermined structure is provided at the other end of each of the pair of power supply wires 20 (the end opposite to the main body 10 side). ing. That is, the other end of each of the first power supply wire 21 and the second power supply wire 22 is connected to the fixing member 40.

  As shown in FIGS. 2 and 3, the fixing member 40 is fixed to, for example, a wall (structure). The fixing member 40 is a fixing metal, for example, and is fixed to the wall with screws or the like. By fixing the fixing member 40 to a structure such as a wall, the power supply wire 20 is fixed to a structure such as a wall, and the position of the power supply wire 20 is determined. The first power supply wire 21 and the second power supply wire 22 are installed in parallel at a predetermined interval, for example.

  In addition, one or a plurality of light source units 30 are installed on the power supply wire 20. In the present embodiment, as shown in FIGS. 2 and 3, the two light source units 30 are installed on the feeding wire 20. By installing the light source unit 30 on the power supply wire 20, predetermined power is supplied to the light source unit 30. Note that the number of light source units 30 to be installed (the number of installations) is not limited to two, and may be increased as needed.

  Thus, the light source unit 30 is installed on the power supply wire 20. As shown in FIG. 2, the light source unit 30 includes a light emitting element 31 a that emits light with a predetermined power supplied via the power supply wire 20. Predetermined light is emitted from the light source unit 30 when the light emitting element 31a emits light. For example, the light source unit 30 is disposed so as to irradiate the lower side, and light from the light source unit 30 is emitted toward the lower side.

  Here, a detailed configuration of the light source unit 30 and a connection relationship between the light source unit 30 and the feeding wire 20 will be described with reference to FIG. FIG. 4 is a cross-sectional view of the light source unit 30 and the feeding wire 20 in the illumination device 1 according to the embodiment.

  As shown in FIG. 4, the 1st electric power feeding wire 21 consists of the insulating film 21b which coat | covers the metal wire 21a and the metal wire 21a. Similarly, the 2nd electric power feeding wire 22 consists of the insulating film 22b which coat | covers the metal wire 22a and the metal wire 22a.

  In addition, the light source unit 30 includes a light emitting module 31 that emits light of a predetermined color, and a housing 32 that houses the light emitting module 31.

  For example, the light emitting module 31 emits white light as illumination light. In the present embodiment, the light emitting module 31 includes one or a plurality of light emitting elements 31a and a substrate 31b on which the light emitting elements 31a are mounted.

  The light emitting element 31a is, for example, an individually packaged surface mount device (SMD) type LED element, such as a resin container (package) and an LED chip (bare chip) disposed in the container. And a sealing member for sealing the LED chip. In this case, an SMD structure LED module is formed as the light emitting module 31 by mounting one or a plurality of SMD type LED elements on the mounting substrate using a flat mounting substrate (PCB or the like) as the substrate 31b. can do.

  When the light emitting element 31a is an SMD type LED element that emits white light, for example, a blue LED chip that emits blue light when energized is used as the LED chip, and a yellow phosphor is used as the sealing member. The contained silicone resin (phosphor-containing resin) can be used.

  The light emitting element 31a itself may be an LED element that is an LED chip (bare chip). In this case, the light emitting module 31 has a COB (Chip On Board) structure in which the LED chip (light emitting element 31a) is directly mounted on the substrate 31b. For example, a COB structure LED module can be configured as the light emitting module 31 by mounting one or a plurality of LED chips (light emitting elements 31a) on the mounting substrate using a flat mounting substrate as the substrate 31b. it can.

  When a COB structure LED module that emits white light is used, for example, a blue LED chip is used as the LED chip (light emitting element 31a), and the blue LED chip is made of a silicone resin containing a yellow phosphor. What is necessary is just to seal with a sealing member.

  The housing 32 is provided with a pair of first arm portion 33a and second arm portion 33b. The pair of first arm portion 33 a and second arm portion 33 b is a connection portion with the power supply wire 20, and extends outward from both sides of the housing 32. Each of the first arm portion 33a and the second arm portion 33b is provided with a groove portion that opens downward. The groove portions of the first arm portion 33a and the second arm portion 33b are formed so as to correspond to the power supply wire 20, the first power supply wire 21 is disposed in the groove portion of the first arm portion 33a, and the second arm portion. The second feeding wire 22 is disposed in the groove portion 33b. When the light source unit 30 is installed on the feeding wire 20, the first arm 33 a (groove) is placed on the first feeding wire 21 and the second arm 33 b (groove) is placed on the second feeding wire 22. Placed.

  A light emitting module 31 is accommodated in the housing 32. Further, a translucent plate 34 is provided in a portion of the housing 32 that faces the light emitting element 31a. As a result, light from the light emitting module 31 (light emitting element 31 a) is radiated toward the outside of the housing 32 through the translucent plate 34.

  Further, a pair of first connector 35 a and second connector 35 b are provided inside the housing 32. The first connector 35a and the second connector 35b are electrically connected to the electrode terminals of the substrate 31b through lead wires, for example. The electrode terminal is electrically connected to the light emitting element 31a by a wiring pattern formed on the substrate 31b.

  Further, the first connector 35 a is electrically connected to the first power supply wire 21. Specifically, the first connector 35a is electrically connected to the metal wire 21a of the first power supply wire 21 by the first screw 36a.

  Similarly, the second connector 35 b is electrically connected to the second power supply wire 22. Specifically, the second connector 35b is electrically connected to the metal wire 22a of the second feeder wire 22 by the second screw 36b.

  The electrical connection between the feeding wire 20 and the light source unit 30 can be performed by a method as shown in FIG. FIG. 5 is a cross-sectional view for explaining a method of connecting the power supply wire 20 (first power supply wire 21 and second power supply wire 22) and the light source unit 30 in the lighting device 1 according to the embodiment.

  First, as shown in FIG. 5A, the first power supply wire 21 and the second power supply wire 22 drawn from the main body 10 (not shown) are fixed at predetermined positions, and the light source unit 30 is fixed to the first power supply wire. 21 and the second power supply wire 22 are placed on top. Specifically, as shown in FIG. 5B, the first arm portion 33 a (groove portion) is placed on the first feeding wire 21 and the second arm portion 33 b (groove portion) is placed on the second feeding wire 22. Put.

  Next, as shown in FIG. 5B, a first screw 36a and a second screw 36b are prepared, and the first power supply wire 21, the second power supply wire 22, and the light source are prepared by the first screw 36a and the second screw 36b. Electrical connection with the unit 30 is performed.

  Specifically, the first screw 36a is screwed from the lateral hole (screw hole) of the first arm portion 33a, and the insulating coating 21b and the metal wire of the first power supply wire 21 are screwed by the screw portion (conductive portion) of the first screw 36a. 21a is penetrated and the thread part of the 1st screw 36a is connected to the 1st connector 35a.

  Thereby, as shown in FIG.5 (c), the 1st connector 35a and the metal wire 21a of the 1st electric power feeding wire 21 can be electrically connected by the screw part of the 1st screw | thread 36a.

  Similarly, the second screw 36b is screwed from the lateral hole (screw hole) of the second arm portion 33b, and the insulating coating 22b and the metal wire 22a of the second feeding wire 22 are connected by the screw portion (conductive portion) of the second screw 36b. The thread portion of the second screw 36b is pierced and connected to the second connector 35b.

  Thereby, the 2nd connector 35b and the metal wire 22a of the 2nd electric power feeding wire 22 can be electrically connected by the screw part of the 2nd screw 36b.

  By connecting the power supply wire 20 (the first power supply wire 21 and the second power supply wire 22) and the light source unit 30 in this way, the power supply wire 20 (the first power supply wire 21 and the second power supply wire) is connected to the light emitting module 31. 22), predetermined power is supplied from the power supply circuit 12. Thereby, the light emitting module 31 emits light, and illumination light is emitted from the light source unit 30.

  Since the screw heads of the first screw 36a and the second screw 36b are exposed to the outside, the screw heads may be made of an insulating material such as resin.

  Here, a power feeding method to the light source unit 30 in the illumination device 1 according to the present embodiment will be described with reference to FIG. FIG. 6 is a diagram for describing a functional configuration of the illumination device 1 according to the embodiment.

  As shown in FIG. 6, in the illuminating device 1 according to the present embodiment, AC power received by the base 11 (not shown) is converted into DC power by the power supply circuit 12, and the DC power is supplied to the feeder wire 20 (first It is supplied to each light source unit 30 via a first feeding wire 21 and a second feeding wire 22). Thereby, the light emitting module 31 (light emitting element 31 a) of the light source unit 30 emits light, and light is emitted from the light source unit 30.

  In the case of the configuration shown in FIG. 6, when the number of installed light source units 30 is predetermined (for example, two), the output power from the power supply circuit 12 is adjusted in advance according to the number of installed light sources. A predetermined amount of light is emitted from the unit 30.

  However, if the number of installed light source units 30 is changed from a predetermined number, the light output of each light source unit 30 varies. For example, as the number of installed light source units 30 is increased, the power supplied to each light source unit 30 decreases, so the light output of each light source unit 30 decreases. For this reason, in each light source part 30, a light quantity becomes small and illumination intensity falls.

  Therefore, in order to prevent the light output of each light source unit 30 from fluctuating even when the number of installed light source units 30 is arbitrarily increased or decreased, power is supplied to the light source units 30 by the method shown in FIGS. Good. FIG. 7 is a diagram for describing a functional configuration of a lighting device according to a modification of the embodiment. FIG. 8 illustrates the frequency of alternating current power and light emitting elements (LEDs) output from a power supply circuit in the lighting device. It is a figure which shows the relationship with the electric current ratio which flows.

  As shown in FIG. 7, in the lighting device according to this modification, the power supply circuit 12 includes an AC / DC circuit (converter) and a DC / AC circuit (inverter). In this case, the AC power received by the base 11 is once converted into DC power by the power supply circuit 12, and then converted into AC power again. The DC / AC circuit is, for example, a half-bridge self-excited inverter, and can change the frequency.

  Each light source unit 30 includes a capacitor C1, a smoothing capacitor C2, a rectifier circuit DB, and a light emitting element 31a (LED).

  The capacitor C1 has one electrode connected to the output terminal of the DC / AC circuit and the other electrode connected to the input side of the rectifier circuit DB. Capacitor C1 acts as reactance with respect to the AC power output from the DC / AC circuit. By the capacitor C1, the current flowing through the light emitting element 31a varies according to the frequency of the AC power output from the DC / AC circuit.

  The rectifier circuit DB is, for example, a bridge-type full-wave rectifier circuit composed of four diodes. The rectifier circuit DB is connected between the power supply wire 20 and the light source unit 30. Specifically, one of the two terminals on the input side of the rectifier circuit DB is connected to the other electrode of the capacitor C1, and the other of the two terminals on the input side of the rectifier circuit DB is the output terminal of the DC / AC circuit. Connected to. The rectifier circuit DB performs full-wave rectification on the AC power obtained through the capacitor C1. The electric power output by the full wave rectification is smoothed by the capacitor C2 and supplied to the light emitting element 31a. The light emitting element 31a emits light by the power rectified by the rectifier circuit DB.

  In the illuminating device configured as described above, the AC power output from the power supply circuit 12 is input to the rectifier circuit DB via the capacitor C1 in each light source unit 30. For this reason, the light quantity (brightness) of each light source part 30 can be changed according to the frequency of the alternating current power which the power supply circuit 12 outputs.

  FIG. 8 shows the relationship between the frequency of the sine wave and the current (current ratio) flowing through the light emitting element 31a (LED) when AC power (sine wave) output from the power supply circuit 12 is input to the circuit of the light source unit 30. FIG.

  As shown in FIG. 8, the current flowing through the light emitting element 31 a depends on the output frequency of the power supply circuit 12. Specifically, the current flowing through the light emitting element 31a increases as the output frequency of the power supply circuit 12 increases.

  With such a circuit configuration, the current flowing through the light source unit 30 (light emitting element 31a) can be made to depend mainly on the output frequency of the power supply circuit 12, so that the light output of the light source unit 30 is the frequency of the power supply circuit 12. Can be changed. That is, the light output of each light source unit 30 can be made constant regardless of the number of installed light source units 30.

  Next, the installation method of the illuminating device 1 is demonstrated. When installing the illuminating device 1, it can carry out with the following method, for example.

  First, as shown in FIG. 2, the base 11 of the main body 10 is attached to the socket 110 of the existing lighting apparatus 100. Thereby, the main-body part 10 in which the power supply circuit 12 was incorporated can be installed in the lighting fixture 100. FIG.

  Next, for example, by pulling the holding member 40, the feeding wire 20 having a necessary length is extended from the main body 10 (the support column 14), and as shown in FIGS. 2 and 3, the fixing member 40 is attached to a wall or the like. Fix it. Thereby, the feed wire 20 can be installed in an arbitrary place with a predetermined length.

  Thereafter, a necessary number of light source units 30 are installed on the power supply wires 20, and the respective light source units 30 and the power supply wires 20 are electrically connected by the method described with reference to FIG. Accordingly, when the power is turned on by a switch or the like, the power output from the power supply circuit 12 is supplied to the light source unit 30 through the power supply wire 20 and the light source unit 30 emits light.

  As described above, the lighting device 1 according to the present embodiment includes the main body 10 having the base 11 and the power supply circuit 12 attached to the socket 110 (illumination power supply unit) of the luminaire 100 that has already been installed, A power supply wire 20 that can be drawn out from the main body unit 10 to an arbitrary place, and a light source unit 30 that emits light with a predetermined power supplied via the power supply wire 20 and is installed on the power supply wire 20 are provided.

  Thus, since the main-body part 10 which has the power supply circuit 12 using the nozzle | cap | die 11 can be attached to the socket 110 of the lighting fixture 100, the already installed lighting fixture 100 can be utilized. Further, since the power supply wire 20 can be pulled out from the main body 10 installed in the lighting fixture 100 to an arbitrary place, the light source unit 30 can be arbitrarily set by installing the light source unit 30 at an arbitrary position of the power supply wire 20. Can be placed in place.

  Thereby, since it can irradiate illumination light to arbitrary places using the already installed lighting fixture 100, illumination light can be irradiated to arbitrary places using the already installed lighting fixture.

  Furthermore, according to the lighting device 1 in the present embodiment, one or a plurality of light source units 30 can be moved to any place with respect to one power supply circuit 12. Thereby, an irradiation area can be changed freely.

  Furthermore, according to the illuminating device 1 in this Embodiment, the power supply circuit 12 and the light source part 30 are installed separately. Thereby, it is possible to suppress the light source unit 30 from being affected by the heat generated in the power supply circuit 12. Conversely, the power supply circuit 12 can be prevented from being affected by the heat generated in the light source unit 30. From this, since the number of installation of the light source parts 30 can be increased easily, the brightness can be improved.

  Furthermore, according to the illuminating device 1 in this Embodiment, the light source part 30 and the main-body part 10 are a different body. Thereby, the light source part 30 can be made small easily and weight reduction can be achieved. Thus, the light source unit 30 can be easily moved.

  In the present embodiment, the light source unit 30 is installed on the power supply wire 20. Specifically, a pair of first power supply wire 21 and second power supply wire 22 are used. Thereby, the feeding wire 20 can be easily pulled out from the main body 10 installed in the lighting apparatus 100 to an arbitrary place. Further, the use of the power supply wire 20 facilitates the installation of the light source unit 30.

  In the present embodiment, a pair of power supply wires 20 is provided with a fixing member 40. Thereby, the feed wire 20 can be easily fixed to a predetermined structure.

  In the present embodiment, the main body 10 is provided with a pull-out amount adjustment unit that can adjust the pull-out amount of the power supply wire 20. Thereby, the length of the power supply wire 20 can be easily changed by adjusting the pull-out amount of the power supply wire 20.

  In the present embodiment, the main body 10 is provided with a circuit case 13 that houses the power supply circuit 12. Thereby, the insulation of the power supply circuit 12 can be ensured easily.

  Further, in the present embodiment, the main body portion 10 is provided with a support column 14 extending from the circuit case 13, and the feeding wire 20 is drawn from the support column 14. Thereby, even if it is a ceiling embedded type lighting fixture, such as a downlight, the electric power feeding wire 20 can be easily pulled out from a ceiling surface.

(Other variations)
As mentioned above, although the illuminating device which concerns on this invention was demonstrated based on embodiment, this invention is not limited to said embodiment.

  For example, in the above embodiment, the fixing member 40 is provided at the other end of the power supply wire 20, but this is not a limitation. In this case, as in the lighting device 2 shown in FIG. 9, in the lighting device 1 shown in FIG. 1, instead of the fixing member 40, a main body 10 </ b> A having a base 11, a case 13 </ b> A, and a column 14 is provided. can do. Thereby, the illuminating device 2 can be installed using two lighting fixtures. That is, the feeding wire 20 can be stretched between the two lighting fixtures. In the present modification, the case 13A can be configured similarly to the circuit case 13, for example. Note that the power supply circuit may not be provided in the case 13A.

  Moreover, in said embodiment, although the ceiling-embedded downlight was illustrated as a lighting fixture and the nozzle | cap | die 11 was illustrated as a power receiving part of the illuminating device 1, it is not restricted to this. For example, the illuminating device 3 provided with the main-body part 10 which has 11 A of power receiving parts of a structure as shown in FIG. 10 may be sufficient. The power reception unit 11A has a structure that is attached to an illumination power supply unit (not shown) of the hooking ceiling body 200 provided on the ceiling. As the power reception unit 11A, for example, a structure similar to an adapter for attaching a ceiling light to the hooking ceiling body 200 can be adopted. In addition, as a lighting fixture, you may use other lighting fixtures, such as a pendant-type lighting fixture (pendant light).

  In the above-described embodiment, the configuration is such that only the pair of power supply wires 20 are pulled out from the main body 10, but this is not a limitation. For example, a plurality of pairs of power supply wires 20 may be drawn from the main body 10. In this case, the plurality of pairs of power supply wires 20 can be drawn, for example, radially.

  In the above embodiment, the power supply wire 20 is drawn out so as to be substantially parallel to the ceiling surface or the floor surface. However, the present invention is not limited to this. For example, the power supply wire 20 may be drawn obliquely downward, or a weight or the like may be attached to the tip of the power supply wire 20 and the power supply wire 20 may be pulled down vertically.

  In the above-described embodiment, the power supply wire 20 is used as a power supply unit (power supply unit) from the main body unit 10 to the light source unit 30, but is not limited thereto. For example, a telescopic pipe or the like may be used as a power feeding unit from the main body unit 10 to the light source unit 30.

  In the above embodiment, the first power supply wire 21 and the second power supply wire 22 that are separated are used as the power supply wire 20, but the number of power supply wires 20 may be one in appearance. That is, it may be one power supply wire in which the first power supply wire 21 and the second power supply wire 22 are bundled. In this case, the light source unit 30 may be configured to be installed on one power supply wire.

  Further, in the above embodiment, the BY type LED module that emits white light is configured by the blue LED chip and the yellow phosphor, but the present invention is not limited thereto. For example, a phosphor-containing resin containing a red phosphor and a green phosphor may be used and combined with this and a blue LED chip to emit white light.

  Moreover, in said embodiment, although the LED chip was used as a light source of a light emitting module, it is not restricted to this. For example, as a light source of the light emitting module, a semiconductor light emitting element such as a semiconductor laser, a light emitting element such as an organic EL (Electro Luminescence) or an inorganic EL, and other solid light emitting elements may be used.

  Other configurations and functions in the above embodiments and modifications may be arbitrarily obtained without departing from the gist of the present invention, or various forms conceived by those skilled in the art with respect to the above embodiments and modifications. Embodiments realized by combining these are also included in the present invention.
