The panels A are stacked one on top of the other and pressed and supported by a pressing member.

  The support frame 16 is a synthetic resin having heat resistance, weather resistance, and electrical insulation, and in this embodiment, a square frame 16a is integrally formed of white PBT in the same manner as the main body frame 14. The size of the frame body 16a is such that the square main body frame 14 having the above-described configuration is disposed inside the frame so that it can be enclosed, and the main body frame 14 is inserted into the frame, whereby a light emitting panel is provided. The main body B of the rectangular lighting fixture comprised of A and the main body frame 14 is supported.

  The support frame 16 is integrally formed with a flange 16b projecting inward on the inner periphery of the frame 16a, and a step 16c (FIG. 4A) is integrated with the tip of the flange 16b. The locking receiving portion 16d formed of a substantially U-shaped groove extending upward in the drawing is integrally formed long along the side of the frame body 16a. The locking receiving portion 16d is formed on each side of the support frame 16 having a rectangular shape, that is, on all four sides. Furthermore, the flange part 16e used as the decoration edge which protrudes toward the outer side of the frame 16a is integrally formed.

  The locking piece portion 14d of the main body frame 14 described above is fitted into the groove of the locking receiving portion 16d, and the main body frame 14 is fitted to one side of the support frame 16 by the locking piece portion 14d and the locking receiving portion 16d. Rotation, that is, the action as the hinge portion C when opening and closing (FIG. 4A), and the locking prevention to prevent the main body frame 14 from being detached from the support frame 16 when opened. (FIG. 4B) is performed. Since the latch receiving portions 16d are formed on the four sides of the square support frame 16, the latch piece portions 14d of the square main body frame 14 are latched to the latch receiving portions on any side. Can do. Further, a receiving piece 16g made of a steel plate is fixed to a side plate 16f located on the opposite side of the support frame 16, and a screw hole 16h is formed in the central portion of the receiving piece (FIG. 5 (b)).

  The lighting device 17 is composed of, for example, a lighting circuit (not shown) that converts an AC voltage of 100 V into a DC voltage of 24 V and supplies it to a light emitting diode chip or the like, and is composed of a steel plate as shown in FIG. A lighting circuit is built in a case member 17a made of a long rectangular parallelepiped. Support holes are formed at both ends of the case member 17a from the side plate 17c to the upper surface plate 17d. The support hole is formed with a large guide hole 17e in the side plate 17c, and a long hole 17f is formed in the upper surface plate 17d continuously to the guide hole. The guide hole 17e can be inserted with a nut 21 of a suspension bolt 20, which will be described later, and the long hole 17f is formed with a dimension that allows the bolt 20 to be inserted but not the nut 21. Further, screw holes 17g for attachment are formed on both side plates 17c of the case member 17a so as to be positioned below the guide holes 17e.

  The case member 17 a incorporating the lighting circuit is configured to be supported by the support frame 16. That is, the case member 17a is arranged so as to straddle the side plate 16f located on the opposite side of the support frame 16, and the both side plates 17c of the case member 17a are inserted into the screw holes 16h of the receiving piece 16g fixed to the side plate 16f. The screw holes 17g are matched so that they can be fixed with screws.

  Further, from one side plate 17c of the case member 17a, a terminal portion 17j connected to the output end of the lighting circuit is drawn out and attached to the tip of the panel side lead wire w connected to the input terminal of the light emitting panel A. The connector 12c is connected (FIG. 6B). In this case, when the case member 17 a is attached to the support frame 16, the case member 17 a is attached so that the side plate 17 c from which the terminal portion 17 j is pulled out faces the vicinity of the groove-shaped locking receiving portion 16 d of the support frame 16.

  The lighting fixture 10 composed of the light-emitting panel A, the main body frame 14, the support frame 16, and the lighting device 17 configured as described above is installed and used on the ceiling surface X that is an installation portion as follows (FIG. 6).

  Note that a square opening h having a size into which the support frame 16 can be inserted is formed in the ceiling X in advance, and two suspension bolts 20 are installed on the support material 30 on the back of the ceiling. The two suspension bolts are installed at intervals roughly matching the distance between the support holes formed at both ends of the case member 17a of the lighting device 17, and two nuts 21 and 21 are attached to each of the suspension bolts ( FIG. 5 (a)).

  First, the lighting device 17 is supported in advance on the support frame 16 as shown in FIG. Next, as shown in FIG. 6 (a), the support frame 16 supporting the case member 17a of the lighting device is inserted into the ceiling through the opening h of the ceiling X with the case member 17a facing upward. The nut 21 of the left suspension bolt 20 is inserted into one of the support holes, in this embodiment, the guide hole 17e of the left support hole in FIG. At this time, the lower nut 21 of the two nuts 21 is inserted into the guide hole 17e, and the bolt 20 is inserted into the elongated hole 17f. The upper nut 21 faces the upper surface plate 17d of the case member 17a. Similarly, the right suspension bolt 20 is bent, the lower nut 21 is inserted into the guide hole 17e, and the bolt 20 is further inserted through the long hole 17f.

  In this state, the support frame 16 is aligned with the opening h. At this time, the bolt 20 is slid left and right within the elongated hole 17f of the case member 17a so that the knurled surface around the opening h is hidden by the flange portion 16e serving as a decorative edge of the support frame 16. In this state, the mounting position of the support frame 16 with respect to the ceiling X is determined. In this state, the two nuts 21 of each suspension bolt 20 are tightened to fix the case member 17a to the two suspension bolts 20. Accordingly, the support frame 16 is fixed to the support member 30 on the back of the ceiling via the case member 17a of the lighting device (FIG. 6A).

  At this time, since the lighting device 17 is fixed in a state of straddling the support frame 16, openings a are formed on both sides of the lighting device (FIG. 5A). This is done while observing the state of the suspension bolt 20 and nut 21. In addition, the installation work on the ceiling surface X is performed only on the light support frame 16 made of synthetic resin without the support frame 16 being attached with the main body B of the lighting fixture in which the light emitting panel A and the main body frame 14 are integrated. Lift up and install.

  Next, the main body frame 14 is lifted, and the locking piece portion 14 d of the main body frame 14 is fitted into the groove of the locking receiving portion 16 d formed on the inner periphery of the support frame 16. At this time, since the latch receiving portions 16d are formed on the four sides of the support frame 16 having a square shape, the latch piece 14d of the main body frame 14 is latched to the latch receiving portions 16d on any side. Therefore, by looking at the situation of obstacles near the ceiling, select and decide which side to be locked. As described above, the main body frame 14 is supported in a state of being suspended from one side of the support frame 16 (FIG. 6B).

  Next, with respect to the frame body 14a of the main body frame 14 in the suspended state, the light control body 19, the light transmitting plate 18, and the light emitting panel A are sequentially overlapped and inserted on the inner surface of the inner flange portion 14n. The main body frame 14 and the light emitting panel A are integrated by pressing and supporting with a pressing member (FIG. 6B).

  Next, the connector 12c of the lead wire w on the light emitting panel A side is connected to the terminal portion 17j drawn out from the one side plate 17c of the case member 17a of the lighting device 17. At this time, since the wiring connection between the lighting device 17 and the light emitting panel A can be performed on the hinge C side, the light emitting panel side lead wire w may be short. These operations can be performed in a state where the main body frame 14 is drawn out of the support frame 16 and is suspended, and the workability is improved.

  As described above, since the hinge portion C is configured in a state where the locking piece portion 14d is locked to the locking receiving portion 16d, the locking piece portion 14d of the main body frame 14 is rotated around the locking receiving portion 16d as an axis. Move. That is, the main body frame 14 integrated with the light emitting panel A is locked to one side of the support frame 16, and the main body frame 14 is inserted into the support frame 16, in other words, the light emitting panel A. Then, the support frame 16 is rotated so as to close the opening (in the direction of the arrow in FIG. 6B).

  Thereby, the engaging portion 14 e provided on the side opposite to the side locked by the main body frame 14 abuts on the flange portion 16 b of the support frame 16. In this state, as shown in FIGS. 1B and 1C, the screw head 14e3 of the stopper 14e1 exposed on the surface of the main body frame 14 is rotated to the left or right using a flat-blade screwdriver. 14e5 is protruded from the side surface 14k of the main body frame 14, and is engaged with the flange portion 16b of the support frame 16 from the inner surface. Thereby, one side of the main body frame 14 is engaged and supported by the engaging portion 14e by fitting the locking piece portion 14d and the locking receiving portion 16d of the support frame 16 together.

  At this time, the convex portion 14e4 of the stopper 14e1 is fitted into the small hole 14e6 of the cylindrical portion to prevent further rotation of the metal rod, and the stopper piece 14e5 loosens and rotates due to vibration or long-term use. The light emitting panel A can be reliably engaged with the support frame 16 without being disengaged from the inner surface of the flange portion 16b of the support frame 16, and safety against the possibility of dropping or the like is maintained.

  As described above, the lighting fixture 10 including the light-emitting panel A, the main body frame 14, the support frame 16, and the lighting device 17 is installed on the ceiling X. The opening h of the ceiling is covered with a flange 16e which is a decorative edge of the support frame 16, and the flange 16e and the flange 14b of the main body frame 14 are flush with each other so that the ceiling surface X is installed in a flat state. The appearance is also improved.

  When the lighting fixture 10 installed above is turned on, the LED 11 of the light emitting panel A emits white light. The light emitted from the LEDs is emitted downward and laterally, reflected by the reflecting surface 11h of the reflector 11c, and illuminated with a wide, substantially circular light distribution that irradiates the entire surrounding area including directly under the fixture. At the same time, a part of the light reflected by the reflecting surface 11h is emitted toward the side of the appliance, and irradiates the ceiling surface X over a wider range.

  Further, the heat generated from each LED 11 at the time of lighting is radiated to the outside from the base 11a through the steel plate heat radiating plate 11j. The heat of the lighting device 17 is also radiated through the case member 17a made of a steel plate. As a result, the light emission efficiency of the LED can be prevented from being lowered, the light flux can be prevented from being lowered due to the temperature rise, and the life of the LED can be extended. In addition, the reliability of the circuit components of the lighting device 17 can be improved.

  Next, when taking out the light emission panel A, such as maintenance of LED etc. used as a light source, it removes as follows. First, as shown in FIGS. 1B and 1C, the screw head 14e3 of the stopper 14e1 exposed on the surface of the main body frame 14 is rotated to the left or right using a flat-blade screwdriver. The engagement with the inner surface of the flange 16b of the support frame 16 is released. At this time, the convex portion 14e4 of the stopper 14e1 rotates using the elasticity of the resin, and comes off from the small hole 14e6 of the cylindrical portion.

  In this state, the locking piece 14d of the main body frame 14 is rotated about the locking receiving portion 16 of the support frame 16 as an axis, and is rotated so as to open the main body frame 14 from the opening of the support frame 16 ( FIG. 4 (a) → (b)). Thereby, the hook-shaped locking piece portion 14d of the main body frame 14 is locked in the groove of the locking receiving portion 16d. As a result, the main body frame 14 is locked and suspended so as not to be detached from the support frame 16 in the opened state.

  In this state, the pressing member that holds the light emitting panel A against the main body frame 14 may be removed, and the light emitting panel A may be pulled out from the main body frame 14. When the light emitting panel is removed together with the main body frame 14, as shown in FIG. 4C, the groove of the locking receiving portion 16d and the hook-like locking piece portion 14d of the main body frame 14 are locked. Then, the main body frame 14 and the light emitting panel A are removed from the support frame 16 by further rotating in the opening direction to release the locking state between the hook-shaped locking piece portion 14d and the groove of the locking receiving portion 16d. Can be removed.

  As described above, according to the present embodiment, the main body frame 14 formed with the locking piece portion 14d protruding in a hook shape on one side, and the groove shape for fitting the locking piece portion 14d of the main body frame 14 on each side forming a square. Since the support frame 16 in which the latch receiving portion 16d is formed is configured, only the light support frame 16 can be first installed on the ceiling X. It can be performed while observing the state of the bolts 20 and nuts 21 and the like, and the construction becomes easy.

  Further, the support frame 16 is first installed on the ceiling X, and the locking piece portion 14d of the main body frame 14 is fitted to the locking receiving portion 16d of the support frame 16 that has already been installed, so that the main body frame 14 is attached to the support frame 16. In this state, the light emitting panel A can be attached to the main body frame 14, and the installation work on the ceiling surface X is performed by a lighting fixture in which the light emitting panel A and the main body frame 14 are integrated with the support frame 16. It is only necessary to lift and install the light support frame 16 made of synthetic resin without attaching the main body B, and it is possible to work without supporting a relatively heavy object such as a lighting device as in the past. Due to these effects, it is possible to facilitate the workability of the installed part such as the ceiling in the lighting apparatus using the light-emitting panel as a light source. In particular, in a lighting fixture that employs an LED as a light source and is reduced in weight, it is possible to provide a lighting fixture that is more excellent in workability in combination with the weight reduction of the main body.

  Further, since the latch receiving portions 16d of the support frame 16 are formed on the four sides of the square support frame 16, the latch piece portions 14d of the square main body frame 14 are connected to the latch receiving portions on any side. Since it can be locked, the state of the obstacle near the ceiling, etc., and determining whether the main body frame 14 can be opened and closed with respect to the support frame 16, etc. It is possible to select and determine whether or not the 14 locking piece portions 14d are to be fitted, and it is possible to provide a lighting fixture with excellent workability. At the same time, it is possible to prevent the main body frame 14, that is, the light-emitting panel A from hitting an obstacle on the ceiling surface X and the like from being removed due to maintenance after installation. Moreover, since the latching piece part 14d and the latching receiving part 16d are formed long along one side and can fit both together reliably, the reliable hinge part C can be comprised, The operability at the time of opening and closing the frame 14 is good, and rattling or the like does not occur. Further, the gap between the main body frame 14 and the support frame can be hidden by the long locking piece portion 14d and the locking receiving portion 16d, and the appearance is also improved.

  Moreover, since the case member 17a of the lighting device 17 is attached to the support frame 16, the lighting device 17 can be installed simultaneously with the installation of the support frame 16 on the ceiling X, and the construction is further simplified. Further, since the terminal portion 17j of the lighting device 17 is provided facing the groove-shaped locking receiving portion 16d of the support frame 16, that is, the vicinity of the hinge side C, the lead for connecting the lighting device 17 and the light emitting panel A with wires. Since the wire w is short and the lead wire is not disposed unnecessarily long on the surface of the light emitting panel A, the lead wire does not get in the way during installation work and maintenance work, making it easier to work and disconnecting. Etc. are prevented. At the same time, the material cost can be reduced, and a cost-effective lighting apparatus can be provided.

As described above, in the present embodiment, the locking receiving portions 16d of the support frame 16 are formed on all four sides of the support frame 16, but may be formed only on the side facing the stopper 14e1 that is the engaging portion 14e. Good. Although the locking receiving portion 16d and the locking piece portion 14d are formed long along the side, either one or both may be formed shorter than the length of the side. The preferred embodiments of the present invention have been described above, but the present invention is not limited to the above-described embodiments, and various design changes can be made without departing from the scope of the present invention.
The invention described in the scope of claims before amendment of the present application will be appended below.
