  The present invention relates to an LED lighting fixture having a light source as a light-emitting diode, and more particularly to an LED lighting fixture mounting / falling prevention device.

  In recent years, LED lighting fixtures in which light sources are light-emitting diodes (LEDs) whose light source is low in power consumption have been rapidly sold. Companies, factories, and offices generally use straight tube fluorescent lamps, and when changing from fluorescent lamps to light-emitting diode lighting fixtures, remove the fluorescent lighting fixtures from the ceiling surface, It is normal to install a new LED lighting fixture. At that time, power supply construction is also required.

FIG. 33 shows a front view of a conventional lighting fixture main body 80 using a light emitting diode as a light source. The horizontal dimension is, for example, 100 cm, but the horizontal dimension is drawn with compression for convenience. .
FIG. 34 shows an exploded view of the luminaire main body 80. The luminaire main body 80 includes a metal case main body 81, a metal cover 82 covering the opening surface of the lower surface of the case main body 81, and the cover. The light emitting unit 83 is detachably mounted on the lower surface side of the 82.

It is attached. In addition, 89 is a pin hole into which the pin 90 (refer FIG. 34) of the light emission part 83 is inserted.
Further, a screw hole 87 to be described later is screwed into the end portion of the mounting bracket 86. Further, a substantially U-shaped lamp holder 87 is provided on the socket 85 side so as to be swingable.

  FIG. 37 shows a cover 82. The cover 82 has a substantially flat plate shape, and ribs 91 are integrally formed on both sides. In addition, notches 93 are formed at both ends of the cover 82 to allow the connectors 92 (see FIG. 34) at both ends of the light emitting portion 83 to escape. Screw insertion holes 94 are formed in the notches 93, respectively.

  As shown in FIG. 34, the light emitting portion 83 is formed in a substantially cylindrical shape, and a printed circuit board on which light emitting diodes are linearly mounted is housed. The lower part of the outer shell of the light emitting portion 83 is made of resin and has a milky white translucency. Further, connectors 92 each having a pin 90 projecting are formed on the upper surfaces of both ends of the light emitting portion 83.

Next, attachment of the conventional lighting fixture body 80 to the ceiling surface will be described. First, as shown in FIG. 38A, the case main body 81 is arranged at a predetermined position on the ceiling surface, and a screw 95 is inserted into the mounting hole 84 of the case main body 81 from below the case main body 81 so that the screw 95 is inserted. Screw onto the ceiling. Thereby, the case main body 81 can be attached to a ceiling surface.
Next, as shown in FIG. 38 (b), the cover 82 is fitted into the opening on the lower surface of the case body 81 so that the rib 91 of the cover 82 is inserted inside the case body 81. While the cover 82 is fitted to the lower surface of the case body 81, the cover 82 is pressed by hand, and the cover 82 is attached to the case body 81 with screws 96 from below.

Specifically, the screw 96 is inserted into the hole 94 of the cover 82 and further screwed into the screw hole 87 of the mounting bracket 86 in the case main body 81, so that the cover 82 is attached to the case main body 81 by the screw 96. Installed.

Furthermore, the operation of screwing into the screw hole 87 is very dangerous. In addition, when installing a lighting fixture, there is a problem that it is difficult to find the hole 94 through which the screw 96 is inserted because the work site is not light and is dim. That is, there is a problem that workability of the conventional lighting fixture main body 80 attached to the ceiling surface is very poor.

Further, after the light emitting unit 83 is attached to the case main body 81, the lamp holder 88 is rotated to prevent the light emitting unit 83 from falling by the lamp holder 88. When attaching, the lamp holder 88 may be forgotten to rotate.
In such a case, since the light emitting portion 83 has a structure in which the pin 90 is inserted into the pin hole 89 of the case main body 81 from below, if the light holder 83 is forgotten to rotate, the light emitting portion 83 is self-weighted. May cause the light emitting unit 83 to fall naturally or even in a small earthquake.

  Further, when a large earthquake occurs, the lamp holder 88 itself is not firmly fixed but is in a swinging state, so that the lamp holder 88 may rotate outward and come off from the light emitting portion 83. In such a case, there is a problem that the light emitting unit 83 falls and enters a more dangerous state.

Next, as shown in FIG. 23, the holding part 47 of the engaging body 40 is held, or the holding part 47 is pushed outward (to the right in FIG. 23) with a finger. Then, as shown in FIG. 24, when the engaging body 40 is slid outward in the groove 14, the engaging piece 46 of the engaging body 40 is engaged with the first fitting of the base plate 2 as shown in FIG. 25. Enter hole 15.

When the engagement body 40 is further slid, as shown in FIG. 26, the engagement piece 46 of the engagement body 40 has the first fitting hole 15 of the base plate 2 and the second fitting hole of the instrument body 3. 28 to be elastically restored. FIG. 27 shows a CC cross section of FIG.
As shown in FIGS. 26 and 27, the engagement piece 46 of the engagement body 40 is fitted into the first fitting hole 15 and the second fitting hole 28, and the engagement piece 46 is the rib of the instrument body 3. It will be in the state which protruded inside from 23.

  Thus, the engagement piece 46 of the engagement body 40 attached to the groove 14 of the base plate 2 protrudes from the first fitting hole 15 and is above the second fitting hole 28 at the upper end surface of the engagement piece 46. The instrument main body 3 can be securely and firmly attached to the base plate 2 by engaging with the inner surface of the base plate 2. Further, since the engaging body 40 is held in the groove 14 by the pressing piece 42, it does not slide naturally, and the engaging piece 46 falls off from the first fitting hole 15 and the second fitting hole 28. Never do.

  In particular, the engagement piece 46 of the engagement body 40 protrudes inward from the second fitting hole 28 of the instrument body 3 as shown in FIGS. Since the instrument body 3 is received by the engagement piece 46 in the orthogonal direction, the engagement piece 46 does not bend, so that the instrument body 3 can be supported by the engagement piece 46. Therefore, the possibility that the instrument main body 3 falls from the base plate 2 can be avoided 100%.

Thus, in this embodiment, after aligning the instrument body 3 from below with respect to the base plate 2 attached to the ceiling surface, simply sliding the engagement body 40 along the groove 14 in the lateral direction, The instrument body 3 can be attached to the base plate 2 simply, reliably and smoothly.
Unlike the conventional case where the cover 82 is also screwed to the case body 81, the engaging body 40 is simply slid, so that the installation work of the luminaire body 1 can be made smooth and the mounting workability can be improved. It can be greatly improved.

  Moreover, since the lighting fixture body 1 is attached to the ceiling surface, it can be smoothly attached even in high-altitude work, and safety can be improved. In addition, after installing the luminaire main body 1 on the ceiling surface, the fixture main body 3 is not dropped by using a separate member as in the prior art. The fitting body 15 can be reliably prevented from dropping from the base plate 2 as well as being attached to the fitting body 15 simply by fitting into the fitting hole 15 and the second fitting hole 28.

Next, the case where the engagement body 40 is further slid rightward from the state of FIG. 26 will be described. When the engagement body 40 is slid rightward from the state of FIG. 26, as shown in FIGS. 28 and 29, the end edges on both sides of the L-shaped piece 45 of the engagement piece 46 are the first fitting holes 15. Then, the engagement body 40 cannot be slid further by contacting the inner edge of the second fitting hole 28.
That is, the tip portion of the L-shaped piece 45 of the engaging piece 46 of the engaging body 40 is erected, and the tip surface of the L-shaped piece 45 is opposed to the inner edges of the fitting holes 15 and 28. Even if the united body 40 is slid to the right, the end edge of the L-shaped piece 45 hits the inner edge of the fitting holes 15 and 28, and the engaging body 40 cannot be slid any more. Thereby, the engaging body 40 cannot be easily removed from the groove 14.

  Although the edges of the fitting holes 15 and 28 are arcuate, when the shape of the fitting holes 15 and 28 is rectangular, the front end surface of the engaging piece 46 is fitted to the fitting holes 15 and 28. It is difficult to contact the inner edge of 28 and slide it further as described above.

  When the engaging body 40 is inserted into the groove 14 of the base plate 2 for the first time, since the inclined piece 44 is provided in the engaging body 40, the inclined piece 44 is fitted even after entering the fitting hole 15. The inner edge of the joint hole 15 can be easily overcome.

Next, the case where the fixture body 3 is removed from the base plate 2 for some reason such as failure after the lighting fixture body 1 is installed on the ceiling surface will be described. As shown in FIG. 30, in a state where the engagement piece 46 of the engagement body 40 is engaged with the engagement holes 15 and 28, the engagement body 40 is slid leftward in the drawing.
When the engagement body 40 is slid to the left, the inclined piece 44 of the engagement body 40 hits the inner edge of the fitting hole 15 as shown in FIG. It is possible to easily get over from the hole 15.

  Further, as shown in FIG. 32, when the engaging body 40 is slid leftward, the engaging piece 46 completely gets over the fitting hole 15 and is positioned in the groove 14. Accordingly, the engagement piece 46 of the engagement body 40 can be completely moved from the fitting holes 15 and 28. Therefore, the instrument body 3 can be easily detached from the base plate 2 by shifting the instrument body 3 downward as it is. be able to.

In the above-described embodiment, the number of the fitting holes 15 and 28 that engage with the engaging pieces 46 of the engaging body 40 is described as two places on both sides of the lighting fixture body 1. You may provide two or more places according to the direction dimension.
Further, even if the first fitting hole 15 of the base plate 2 and the second fitting hole 28 of the instrument body 3 do not completely match in the front-rear direction, the engagement piece 46 of the engagement body 40 is inserted. The fitting holes 15 and 28 may be communicated with each other in a size to be achieved. That is, the lateral positions of the fitting holes 15 and 28 may be slightly shifted.

In the above embodiment, the groove 14 for sliding the engagement body 40 is formed in the base plate 2. However, only the first fitting hole 15 is drilled in the base plate 2, and the casing 20 of the instrument body 3 is formed. You may make it form the groove | channel 14 which slides the engaging body 40 in an outer surface.
In this case, the ribs 23 of the casing 20 are located outside the side plates 12 of the base plate 2, and the grooves 14 are formed by the protruding ribs 13 on the outer surface of the ribs 23.

  Moreover, although the installation surface of the lighting fixture main body 1 was demonstrated as a ceiling surface, it is not restricted to a ceiling surface. For example, when the luminaire main body 1 is installed on a wall surface, or when the luminaire main body 1 is used as indirect lighting, the base plate 2 is placed on the lower side, the fixture main body 3 is fitted on the upper surface of the base plate 2, and the fixture The light from the main body 3 may be used so as to be reflected downward on the ceiling surface.
