  The lighting fixture 1 of this embodiment is provided with the lighting unit 10 which has the light emission part 11 in the fixture main body 12, and the charger 20 to which the lighting unit 10 is connected so that attachment or detachment is possible, as shown in FIG. In the example of FIG. 1, a plurality of lighting units 10 (three in this case) are provided, but the number of lighting units 10 constituting the lighting fixture 1 can be arbitrarily changed. In the following, for the sake of simplicity of explanation, the upper and lower sides of the state in which the lighting unit 10 is connected to the charger 20 placed on the table (that is, the upper and lower sides in FIG. 1B) are described as the upper and lower sides. It is not intended to limit the orientation of the lighting fixture 1 at the time.

  As shown in FIG. 2, the lighting unit 10 includes a secondary battery 13 and a control circuit unit 14 in the instrument main body 12, and the control circuit unit 14 turns on the light emitting unit 11 by the output of the secondary battery 13. The instrument body 12 is formed in a substantially disk shape that is circular in plan view as shown in FIG. A protrusion 15 is formed on the upper surface of the instrument main body 12 so that the upward protrusion amount increases as it approaches the center of the circle. On the lower surface of the instrument main body 12, the depression amount increases as it approaches the center of the circle. A concave portion 16 is formed in which becomes larger. By forming the protrusion 15 and the recess 16 in this way, the instrument main body 12 has an umbrella shape as a whole.

  Here, the protrusions 15 and the recesses 16 are formed in shapes corresponding to each other, and the plurality of illumination units 10 are arranged such that the protrusions 15 of one illumination unit 10 fit into the recesses 16 of the other illumination units 10. , Can be stacked and integrated in the vertical direction. That is, a plurality of lighting units 10 can be stacked in the vertical direction with the central axis aligned. In a state in which the plurality of lighting units 10 are stacked, the protrusions 15 of the lighting units 10 one step below are fitted in the recesses 16 of the respective lighting units 10.

  In other words, the plurality of lighting units 10 use the protrusion 15 and the recessed portion 16 as first and second connecting portions that are connected to each other, and connect the protruding portion 15 and the recessed portion 16 to connect the instrument body 12. Are integrated in a state of being stacked in one direction (vertical direction).

  In the present embodiment, the light emitting unit 11 includes a plurality of light emitting diodes (not shown) housed in the instrument body 12 as a light source. The light emitting diode outputs white light suitable for illumination. Furthermore, the light emitting unit 11 includes a light guide member (not shown) made of, for example, acrylic resin and guiding light emitted from the light emitting diode in the instrument main body 12. The light guide member is provided along the outer periphery of the instrument body 12 so that the light emitted from the light emitting diode is uniformly emitted from the entire circumferential direction of the instrument body 12.

  The instrument main body 12 constitutes a light extraction portion 122 that transmits light from the light emitting portion 11 except for the main body portion 121 formed within a certain range from the center of the circle. The light extraction part 122 is formed of a material having a diffuse transmission property such as milky white translucent synthetic resin or glass, for example, and the light emission part 11 is directly viewed from the outside of the instrument body 12 while taking out the light of the light emission part 11 to the outside. To prevent it. Therefore, when the light emitting unit 11 is turned on, the entire annular light extraction unit 122 provided in the instrument main body 12 shines evenly.

  Here, the secondary battery 13 and the control circuit unit 14 are accommodated in the main body 121 of the instrument main body 12 so that the light extracted from the light extraction unit 122 does not cause shadows of the secondary battery 13 and the control circuit unit 14. Yes. The secondary battery 13 is made of, for example, a nickel metal hydride storage battery or a lithium ion storage battery, and is electrically connected to the control circuit unit 14.

  In addition, connectors 17 and 18 used for electrical connection between the lighting units 10 and electrical connection with the charger 20 are formed in the main body 121 of the appliance main body 12. As will be described in detail later, the connectors 17 and 18 are also used for coupling the instrument main body 12 to other members when each lighting unit 10 is used alone.

  Specifically, a first connector 17 as a power receiving unit is formed at the center of the recess 16 on the lower surface of the instrument body 12, and a second connector 18 is formed at the center of the protrusion 15 on the upper surface of the instrument body 12. Has been. The second connector 18 has a pair of blade receiving members (not shown) provided in the back of the pair of insertion ports 181 formed in the instrument body 12, and the first connector 17 It has a pair of plug blades 171 which are inserted into the inlets 181 and come into contact with the blade receiving members. Thereby, in the state in which the plurality of lighting units 10 are stacked, the first connector 17 of each lighting unit 10 is connected to the second connector 18 of each lower lighting unit 10. Become.

  As shown in FIG. 2, the first connector 17 and the second connector 18 provided in the same lighting unit 10 are connected to each other in the instrument main body 12, and further to these connectors 17, 18. The control circuit unit 14 is electrically connected. Note that the polarities of the connectors 17 and 18 are determined, and by adopting different shapes for the plug blades of the first connector 17 depending on the polarities, the plurality of lighting units 10 are oriented in the direction in which the connectors 17 and 18 have opposite polarities. Are prohibited from being stacked. Further, each of the connectors 17 and 18 may be configured to be connected with a correct polarity regardless of the direction of the illumination unit 10, such as a coaxial connector.

  The control circuit unit 14 includes a charging / discharging circuit for the secondary battery 13, and supplies power from the charger 20 via the first connector 17 in a state where the lighting unit 10 is connected to the charger 20. In response, the secondary battery 13 is charged. On the other hand, when the lighting unit 10 is detached from the charger 20, the control circuit unit 14 outputs the charge accumulated in the secondary battery 13 to the light emitting unit 11.

  In the present embodiment, as an example, the secondary battery 13 is charged so that the time required for charging the secondary battery 13 is about 10 hours, and the time that the light emitting unit 11 can be kept lit by the secondary battery 13 is also about 10 hours. Thirteen capacities and charging currents are determined.

  The charger 20 has a body 21 formed in a substantially disk shape that is circular in plan view, and has a power feeding circuit portion (not shown) in the body 21. The body 21 is formed in substantially the same shape and size as the fixture main body 12 of the lighting unit 10, and a protrusion 22 is formed on the upper surface thereof so that the upward protrusion amount increases as the center of the circle is approached. Has been. However, the shape of the body 21 is different from that of the instrument body 12 in that the lower surface is formed in a planar shape. Note that, unlike the instrument body 12, the body 21 is formed entirely of a material that does not have optical transparency.

  Since the charger 20 includes the body 21 having the shape described above, the lighting unit 10 can be stacked on the charger 20 in the same manner as the other lighting units 10 are stacked. In a state where the lighting unit 10 is stacked on the charger 20, the protrusion 22 of the charger 20 fits into the recess 16 of the lighting unit 10 immediately above the charger 20.

  The body 21 is formed with a third connector 23 as a power feeding unit used for electrical connection with the lighting unit 10. Specifically, a pair of insertion ports 231 is formed at the center of the protrusion 22 on the upper surface of the body 21, and a pair of blade receiving members (not shown) constituting the third connector 23 at the back of the insertion port 231. Z). The third connector 23 employs a configuration common to the second connector 18 of the lighting unit 10. Thereby, in the state where the lighting unit 10 is stacked on the charger 20, the first connector (power receiving unit) 17 of the lighting unit 10 directly above the charger 20 is the third connector (power feeding unit) of the charger 20. 23.

  The third connector 23 is connected to the power feeding circuit unit in the body 21. In addition, a power cord 24 drawn from the body 21 is also connected to the power feeding circuit portion. The power supply circuit unit is connected to a commercial power source via the power cord 24 by connecting a power plug 25 provided at the tip of the power cord 24 to a power outlet (not shown).

  The power supply circuit unit includes an AC / DC converter, converts AC power supplied from a commercial power supply via the power cord 24 to DC power, and outputs the DC power to the third connector 23. Therefore, in a state where the lighting unit 10 is connected to the charger 20, DC power is supplied from the charger 20 to the lighting unit 10 via the third connector 23 and the first connector 17, and secondary power is supplied by this DC power. The battery 13 is charged.

  Here, since the 1st connector 17 and the 2nd connector 18 are connected within the instrument main body 12, the state by which the several lighting unit 10 was piled up with respect to the charger 20 as shown in FIG. Then, the plurality of lighting units 10 are connected to the charger 20 in parallel. Therefore, the plurality of lighting units 10 are simultaneously supplied with power from the third connector 23 which is a power feeding unit of one charger 20 to the first connector 17 which is each power receiving unit. The next battery 13 is charged together.

  The power feeding circuit unit estimates the number of lighting units 10 connected to the charger 20 based on the state of the load connected to the third connector 23, and supplies power corresponding to the estimated number of lighting units 10 to the first power unit. 3 to the lighting unit 10. For example, in the state where two lighting units 10 are connected to the charger 20, the current supplied from the power feeding circuit unit is doubled compared to the state where only one lighting unit 10 is connected.

  In each lighting unit 10, the control circuit unit 14 monitors the remaining capacity of the secondary battery 13, and when the secondary battery 13 is fully charged, the floating charging system replenishes only the discharge of the secondary battery 13. Thus, the secondary battery 13 is maintained in a fully charged state.

  In the present embodiment, the control circuit unit 14 supplies the power supplied from the power supply circuit unit to the light emitting unit 11 even during the period in which the lighting unit 10 is connected to the charger 20 and is supplied with power from the charger 20. The light emitting unit 11 is turned on by giving. That is, the control circuit unit 14 outputs a part of the power supplied from the power supply circuit unit to the light emitting unit 11 while charging the secondary battery 13 with the power supplied from the power supply circuit unit. Light up. At this time, the secondary battery 13 smoothes the power supplied from the control circuit unit 14 to the light emitting unit 11. Further, the control circuit unit 14 continues to supply power to the light emitting unit 11 to light the light emitting unit 11 even when the secondary battery 13 is fully charged.

  Therefore, as shown in FIG. 3, when a plurality (four in this case) of lighting units 10 are stacked on the charger 20 and are in a charged state, all of the plurality of lighting units 10 are turned on. Therefore, according to the number of the lighting units 10 stacked on the charger 20, the light output as the whole lighting fixture 1 changes, and the light output as the whole lighting fixture 1 increases as the number of the lighting units 10 increases. growing. At this time, the plurality of lighting units 10 are in a state where the instrument main body 12 is stacked in one direction by connecting the protrusion (first connecting portion) 15 and the recess (second connecting portion) 16 to each other. As a whole, it is possible to achieve a unified design.

  By the way, since each lighting unit 10 has the secondary battery 13 as described above, the control circuit unit 14 emits the electric charge accumulated in the secondary battery 13 when it is detached from the charger 20. By outputting to the unit 11, the light emitting unit 11 can be lit alone. That is, the plurality of lighting units 10 are charged with power from a single charger 20 to each control circuit unit 14 at the same time when charging the secondary battery 13, and charge each secondary battery 13 together. In use, the light emitting unit 11 can be lit alone by being detached from the charger 20.

  Each lighting unit 10 removed from the charger 20 is carried by the user as a single unit, or is placed in an arbitrary place such as a tabletop, a bed, or a floor, thereby enabling portable lighting. Used as

  Furthermore, the illumination unit 10 has a holding portion held by another member in the instrument main body 12. In the present embodiment, the first connector 17 and the second connector 18 are also used as a holding portion. Examples of other members that hold the lighting unit 10 include a floor stand 30 shown in FIG. 4 and a desk stand 40 shown in FIG.

  As shown in FIG. 4, the floor stand 30 includes a disk-shaped pedestal portion 31 placed on the floor and a support column 32 extending vertically from the pedestal portion 31. The floor stand 30 has a support portion (not shown) formed at the tip end portion (upper end portion) of the support column 32, and the plug blade 171 of the first connector 17 is inserted into the support portion. The illumination unit 10 in a state of being covered with the tip is held. If such a floor stand 30 is installed in a bedroom, for example, the user usually charges the lighting unit 10 in the living room with the charger 20, and takes the lighting unit 10 when moving to the bedroom. It is also possible to use it on the floor stand 30.

  As shown in FIG. 5, the desk stand 40 includes an arm part 42 attached to the desk 41 and extending upward, and a support part 43 formed at the distal end of the arm part 42. In this desk stand 40, the arm portion 42 is bent so that the distal end portion of the arm portion 42 faces downward, and the support portion 43 is mechanically coupled to the second connector 18, whereby the arm 42 is The lighting unit 10 in a state of being suspended from the tip is held. By using such a desk stand 40, compared with the case where the illumination unit 10 is placed on the desk 41, the desk top surface can be illuminated from a higher position, and the range in which light reaches the desk top surface is widened.

  In addition, it is good also as a structure which provides a retractable handle on the upper surface of the instrument main body 12 of the illumination unit 10, raises the illumination unit 10 by raising the handle when the user carries the illumination unit 10, and hooking the handle on the hand. . In this case, it is desirable that the lighting unit 10 is also suspended from the floor stand 30 or the desk stand 40 by hooking a handle.

  According to the lighting fixture 1 having the above-described configuration, each of the plurality of lighting units 10 has the secondary battery 13, and therefore, the light emitting unit 11 is output by the output of the secondary battery 13 even during a power failure of the commercial power supply. Can be lit. Therefore, the said lighting fixture 1 can be used as emergency lighting fixtures at the time of a power failure.

  In addition, since each lighting unit 10 can be individually separated from the charger 20, each lighting unit 10 can be used alone as a portable lighting fixture or attached to the floor stand 30 or the desk stand 40. . As described above, the lighting unit 10 can be attached to other members such as the floor stand 30 and the desk stand 40, so that the range of usage of the lighting fixture 1 is widened, and the user uses the lighting fixture 1 in various scenes. It becomes possible.

In addition, the plurality of lighting units 10 receive power supply from the power feeding unit (third connector 23) of one charger 20 to each power receiving unit (first connector 17) all at once. The secondary batteries 13 can be charged together. Therefore, it is possible to maintain all the plurality of lighting units 10 in a usable state by one charger 20. Furthermore, the lighting unit 10 is in a period in which power is supplied from the charger 20. Since the light emitting unit 11 is also turned on, the luminaire 1 can be used as stationary illumination. Here, if the number of the lighting units 10 stacked on the charger 20 is changed, there is an advantage that the magnitude of the light output as the whole lighting fixture 1 can be adjusted.

  In addition, the plurality of lighting units 10 are integrated in a state in which the fixture body 12 is stacked in one direction by connecting the protrusion 15 and the recess 16 as the connecting portions to each other, so that the entire lighting fixture 1 As a result, a unified design can be realized. Furthermore, by stacking a plurality of lighting units in the vertical direction, the area occupied by the lighting fixture 1 in a horizontal plane can be reduced, and the lighting fixture 1 can be installed in a relatively narrow space.

  By the way, in the said embodiment, the electric power feeding part of the charger 20 and the power receiving part of the illuminating unit 10 are electrically coupled by direct contact between the conductive members (the plug blade 171 and the blade receiving member). Although power is supplied to the lighting unit 10, the configuration is not limited to this. That is, in the luminaire 1, the power feeding unit and the power receiving unit are electrically connected in a non-contact manner by electromagnetic induction between a primary coil (not shown) and a secondary coil (not shown). A non-contact power feeding method in which power is supplied to the unit 10 may be adopted.

  When the non-contact power feeding method is adopted, for example, the illumination unit 10 has an insertion hole (not shown) formed in the center of the instrument body 12 so that the instrument body 12 is formed in an annular shape, and the charger 20 has an insertion hole. A protrusion (not shown) to be inserted into the body 21 is provided on the upper surface of the body 21. The primary coil is accommodated in the protrusion of the charger 20, and the secondary coil is accommodated around the insertion hole of the illumination unit 10. In this configuration, power can be supplied from the charger 20 to the lighting unit 10 by electromagnetic induction between the primary coil and the secondary coil with the protrusion of the charger 20 inserted into the insertion hole of the lighting unit 10. .

  Further, the floor stand 30 and the desk stand 40 may be configured to be electrically connected to the lighting unit 10 and to supply power from a commercial power source to the control circuit unit 14 of the lighting unit 10. In this case, the lighting unit 10 can turn on the light emitting unit 11 with power supplied from a commercial power source in a state where the lighting unit 10 is attached to the floor stand 30 or the desk stand 40. Further, the lighting unit 10 may be configured to charge the secondary battery 13 with power supplied from a commercial power source while being attached to the floor stand 30 or the desk stand 40.

  The lighting fixture 1 is not limited to a configuration in which a plurality of lighting units 10 are stacked in one direction with respect to a single charger 20, and a plurality of lighting units 10 can be powered simultaneously from a single charger 20. Any configuration that receives supply may be used. That is, when receiving power supply from the charger 20, the plurality of lighting units 10 may be arranged with a predetermined regularity, and may be arranged in a horizontal row, for example.

  In the above embodiment, the lighting unit 10 is configured such that the light emitting unit 11 is always lit by receiving power supply from the secondary battery 13 or the charger 20, but the present invention is not limited to this configuration. For example, the lighting unit 10 or the charger 20 may be provided with a switch (not shown), and the light emitting unit 11 may be turned on / off by operating the switch. Furthermore, in a state where the lighting unit 10 is supplied with power from the charger 20, the control circuit unit 14 may be configured to charge only the secondary battery 13 and not turn on the light emitting unit 11.
