  In particular, as shown in FIG. 2, two partition plates 14 and 14 are provided on the main body frame 10 along the longitudinal direction of the rectangular main body frame 10. The section sandwiched between the partition plates 14 is a place where the power supply unit 30, the connection terminal 40, and the like are juxtaposed with the LED module 20. The partitions between the partition plate 14 and the edge on the long side of the main body frame 10 are places where the LED modules 20 are mounted. That is, the LED module 20 is divided into two portions and juxtaposed on the main body frame 10 with the power supply unit 30 and the connection terminals 40 therebetween.

  In particular, as shown in FIG. 1, the center cover 80 </ b> A includes a fixing device that can be fixed to the main body frame 10 by sliding one edge 88 </ b> A on the short side in the long side direction of the main body frame 10. Therefore, when attaching the lighting device 100 to the ceiling or the like, the center cover 80A can be removed, and after the lighting device 100 is attached to the ceiling or the like, the center cover 80A can be fixed to the lighting device 100.

Any structure may be used as long as the center cover 80A can be prevented from being bent.

  In particular, as shown in FIG. 3, two translucent panels 60 are arranged with a center cover 80A in between. As shown in FIGS. 1 and 2, the translucent panel 60 has a separation dimension (height dimension of the translucent panel 60) between the main body frame 10 and the translucent panel 60 along the direction toward the edge of the main body frame 10. ) To decrease. Note that the distance between the main body frame 10 and the translucent panel 60 (the height dimension of the translucent panel 60) is greater than the dimension at the edge at locations other than the edge, such as the center of the main body frame 10 and the vicinity of the center. Just make it bigger. Thereby, the light from the LED module 20 can be illuminated in a wider range (for example, the direction orthogonal to the longitudinal direction of the main body frame 10), and the light distribution to the ceiling surface can be increased (light distribution characteristics are widened). it can.

  That is, the translucent panel 60 is inclined so that the separation dimension becomes smaller toward the edge of the main body frame 10. Thereby, for example, when the lighting device 100 is installed on the ceiling surface, the light from the translucent panel 60 (LED module 20) is not only irradiated substantially perpendicularly to the ceiling surface but also on the peripheral side of the lighting device 100. Is also irradiated. For this reason, the ceiling surface around the illuminating device 100 can also irradiate light, and the light distribution characteristics can be made wider than before.

And light distribution characteristics can be further expanded.

  In particular, as shown in FIG. 4, mounting holes 11 and 11 for mounting the main body frame 10 to an installation place such as a ceiling are formed in the main body frame 10. Note that the attachment hole 11 is an example, and is not limited to this, and a member such as a hook or a notch may be used as long as the main body frame 10 can be attached to the installation location. Thereby, the main body frame 10 can be installed in an installation place such as a ceiling.

  The main body frame 10 can also be provided with a plurality of screw holes 13. Thereby, it can also be directly attached to the ceiling or the like. Further, the main body frame 10 is formed with wiring holes 12 and 12 for wiring power supply lines and the like at appropriate locations.

  In particular, as shown in FIG. 4, an appropriate length is provided between the partition plates 14 and 14 provided in parallel with the main body frame 10 (for example, about 80 cm, which is a range in which a person can reach both hands with a margin). A handle 50 is provided at a distance. Further, the fixing position of the handle 50 can be determined with the power supply unit 30 in between, for example, considering the balance (center of gravity) between the power supply unit 30 and the main body frame 10 which are relatively heavy. Thereby, the operator can install the lighting device 100 simply by holding the handle 50 and attaching the main body frame 10 to an installation place such as a ceiling surface. That is, it is not necessary to perform a plurality of mounting operations such as mounting the LED module after mounting the housing of the lighting device 100, and the mounting of the lighting device 100 is completed by one mounting operation.

For this reason, compared with the case where a light source part and a power supply part are made into a two-stage structure, the height dimension (thickness) of the illuminating device 100 can be made small, and a thin illuminating device can be implement | achieved.

  In addition, a connector 23 for connecting wiring from the power supply unit 30 is mounted on the substrate of the LED module 20. Moreover, in order to irradiate the light from LED module 20 efficiently, the reflective sheet 22 bent in the cross-sectional view in substantially U shape is provided. Both edges of the reflection sheet 22 are arranged so as to be positioned on both edges of the translucent panel 60. Thereby, it can prevent that the light from LED module 20 leaks inside the illuminating device 100, and can improve the extraction efficiency of light.

  Moreover, since the detachable center cover 80A is disposed adjacent to the translucent panel 60 that transmits the light from the LED module 20, the light from the LED module 20 is not blocked. Further, when attaching the lighting device 100 to the ceiling or the like, the center cover 80A can be removed and the center cover 80A can be fixed after the main body frame 10 is attached to the installation place such as the ceiling. improves.

  Next, a fixing device provided with a slide mechanism for fixing the center cover 80A as the fixed body to the main body frame 10 as the fixed body will be described in more detail.

  FIGS. 6 and 7 are exploded perspective views of main parts in which the center cover 80A of the lighting apparatus 100 according to Embodiment 1 of the present invention is removed and the fixing device provided on one edge 88A of the center cover 80A is enlarged. 6 is viewed from below, and FIG. 7 is viewed from above. FIG. 8 is a main part enlarged plan view showing a fixing device for fixing the center cover 80A to the main body frame 10, and FIG. 9 is a main part enlarged rear view of the fixing piece 110A. FIG. 10 is an exploded side view of the main part with the center cover 80A removed, and FIG. 11 is an enlarged perspective view of the main part related to the temporary fixing mounting structure provided on the center cover 80A and the partition plate 14. FIG.

  The center cover 80 </ b> A is a cover member that covers a section sandwiched between the partition plates 14, that is, a place where the power supply unit 30, the connection terminal 40, etc. are stored (accommodated), and various shapes can be considered according to the shape of the main body frame 10. It is done. In the first embodiment of the present invention, as particularly shown in FIGS. 1 and 6, a slide mechanism for fixing the center cover 80A to the main body frame 10 at one edge 88A on the short side thereof is rectangular.

For example, the center cover 80 </ b> A can be attached to the fixing protrusion 113 by attaching a screw having a head having a diameter larger than the short side of the fixing hole 87 to the distal end portion of the fixing protrusion 113. Thereby, when attaching / detaching the center cover 80A, the work can be performed without dropping the fixed piece 110A, and the work efficiency is improved. Further, since the fixing hole portion 87 also functions as a sliding hole portion that defines the sliding direction, the fixing piece 110A can be slid in parallel with the center cover 80A, and the fixing piece 110A can be easily slid. Can do.

  In particular, as shown in FIG. 6, a lock portion 16 is provided on the side of the main body frame 10 corresponding to the fixed piece 110 </ b> A for keeping the locking piece 111 locked. When the center cover 80A is fixed by the fixing piece 110A, the lock portion 16 functions to push back the center cover 80A, and thereby the locking state between the locking piece 111 and the hole portion 84 can be maintained. . Therefore, it becomes the illuminating device 100 provided with the safer fixing device.

  In the first embodiment of the present invention, a coil spring is used as the lock portion 16. However, any coil spring may be used as long as it functions to push back the center cover 80 </ b> A, and an elastic body such as a leaf spring or rubber is used. Also good.

Can do. In addition, the fixing device of the present invention is used as a fixing device for the center cover 80A that covers the power supply unit 30, the connection terminal 40, and the like of the lighting device 100. In addition, the translucent plate that transmits light from the LED module 20 is used. Also, it can be used when a diffusing plate or a reflecting plate is fixed to the main body frame 10. Furthermore, when used as a cover member for an apparatus that requires regular maintenance (maintenance, inspection, cleaning, etc.), not only the cover member is fixed to the apparatus body, but also the work efficiency at the time of removal is improved. For example, it can be used as a fixing device for fixing a cover member used for air conditioning and the like, and the fixing device according to the present invention can be used in various applications. Furthermore, when used as a fixing device for a cover member fixed to the surface side of the device, the screw head is not exposed unlike the conventional fixing device, so that the fixing device has a good design.

  Next, the slide mechanism and fixing method for fixing the center cover 80A to the main body frame 10 will be described in more detail.

And the recessed part 82 provided in the curved part 81 of the center cover 80A which is a slide mechanism, and the convex part 83 provided in the position corresponding to the partition plate 14 are latched. Thereby, the center cover 80A can be attached to a predetermined place of the main body frame 10 and can be temporarily fixed. Thereby, since the center cover 80A is supported by the space on the main body frame 10 side and the convex portion 83, both hands can be separated from the center cover 80A, and work efficiency is improved.

  Next, the center cover 80A is positioned so as to engage the positioning projections 15 of the main body frame 10 with the positioning hole 86 provided in the center cover 80A. At that time, since the concave portion 82 is formed in a rectangular shape along the edge of the curved portion 81 rather than the convex portion 83 provided in the curved portion 81, the positioning hole 86 and the positioning projection 15 are engaged with each other. The mounting position of the center cover 80A can be corrected to a predetermined position. Thereby, it is not necessary to reattach and work efficiency is further improved.

  Next, the fixed piece 110A, which is a slide mechanism provided at one edge portion 88A of the center cover 80A, is slid in the longitudinal direction of the center cover 80A. Then, since the center cover 80A corresponding to the fixed piece 110A is provided with the slide projection 112 and the slide hole 85 that define the slide direction, the edges 114A, 114B, and 114C of the fixed piece 110A are placed on the main body frame 10 side. It can be slid to be inserted into the groove 17 provided.

  When the locking piece 111 of the fixed piece 110A slides to a predetermined position where the hole 84 is locked, the locking piece 111 and the hole 84 are locked. The fixed piece 110A cannot be slid. Therefore, the center cover 80A can be fixed to the main body frame 10 by a one-touch operation, and work efficiency is improved.

  Furthermore, since the locking device 16 is provided in the fixing device, the locking state between the locking piece 111 and the hole portion 84 can be maintained, and the locking device can be fixed more safely and reliably. In order to release the locked state, by pushing up one edge portion 88A of the center cover 80A toward the main body frame 10, the locking piece 111 is removed from the hole portion 84, and the fixed piece 110A can be slid.
