Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a shade mounting structure of a wall-fixed lighting fixture.

[Conventional technology]

Generally, in a wall-fixed luminaire, since the light of the lamp directly hits the eyes and is dazzling, the lamp is covered with a shade. In addition, in the conventional shade mounting structure of the lighting fixture, the shade is simply screwed to the main body of the lighting fixture.

[Problems to be solved by the device]

However, such a structure is troublesome because the screw must be removed each time the lamp is replaced or cleaned.

An object of the present invention is to provide a shade mounting structure for a lighting fixture, which allows easy lamp replacement and cleaning.

[Means for Solving the Problems]

The shade mounting structure for a lighting device according to the present invention has a lamp housing opening formed on the front surface of the lighting device main body, and a pair of guide strips that open upward on both side edges of the opening.
On the other hand, the shade that covers the opening is box-shaped with a cutout hole formed in the lower surface, opens rearward, and has a pair of locking portions formed on both side edges of the opening. Movably engaged with the section.

[Action]

According to the structure of the present invention, the pair of locking portions of the shade are movably engaged with the pair of guide strips of the luminaire main body, so that the lamp can be exposed only by moving the shade upward. In addition, since the shade is box-shaped, even if the lamp attached to the luminaire main body is large enough to protrude from the front of the luminaire main body, it can be housed inside the shade.

Further, since a cutout hole is formed in the lower surface of the shade, and a pair of locking portions that movably engage with a pair of guide strips of the lighting fixture body are formed on both side edges of the rear opening,
Even when the lamp is large as described above, since the lamp passes through the cutout hole, the shade can be moved in the vertical direction. Further, at this time, since the shade can be moved while grasping the peripheral portion of the cutout hole, there is an advantage that it is easy to handle.

Further, since the light of the lamp illuminates the lower part directly through the cutout hole, the foot becomes brighter, and the light is blocked by the peripheral portion of the cutout hole of the shade so that it is not dazzling even when approaching. Therefore, it is suitable for entrances and the like.

Further, since the guide strip portion is opened upward, the shade can be separated from the main body of the luminaire, and even in the separated state, the shade can be reliably gripped by the cutout hole, so there is no risk of falling.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS. 1 and 2. The structure of the shade mounting portion of the lighting fixture is such that the shade 4 is slidably mounted in the vertical direction in the lamp housing opening 6 formed in the front surface of the lighting fixture body 1.
The lamp 3 and a reflector are housed in the opening 6. A pair of groove-shaped guide strips 2 are formed along both side edges of the opening 6. The upper ends of these guide strips 2 are open upward and the lower ends are closed, so that the shade 4 can be pulled out only from above. on the other hand,
Locking portions 5 that can move along the guide strips 2 are formed on both sides of the shade 4, and the locking portions 5 are formed on the guide strips 2.
Is engaged with. 29 is a wall surface.

The shade 4 is a milky-white acrylic molded product that is a box type that opens rearward. Engaging portions 5 on both sides of the shade 4 are bent in a plane L-shape. Further, a cutout hole 32 is formed on the lower surface of the shade 4, and the cutout hole 32 is formed as small as possible within the limit of allowing the lamp 3 to pass therethrough. I will never enter.

Therefore, when the shade 4 is moved upward as shown in FIG. 2A, the lamp 3 is exposed, and the lamp 3 can be replaced or cleaned. Further, when the shade 4 is pulled out as shown in FIG. 4B, cleaning becomes easier, and since it cannot be removed downward and forward, it is easy to remove, but there is no risk of falling.

If the lateral width of the shade 4 is made slightly larger than the interval between the guide strips 2, the side portions of the shade 4 elastically contact the guide strips 2 to increase the frictional engagement force with the guide strips 2, and as a result, Even if the hand is released in the state in which 4 is pulled up partway, it will not fall back to the original position, and the work efficiency of replacing the lamp 3 and the like can be further improved.

FIG. 3 shows an example in which the shade mounting portion structure of the lighting device configured as described above is applied to the lighting portion of the ventilation device. The ventilation device is provided with a louver mounting opening on the wall surface 29, the lighting fixture A and the ventilation fan B are installed in parallel so as to face the louver mounting opening, and the ventilation fan B is covered with the rattle 20. The ventilation fan B is constructed by mounting a fan main body 13 and a motor on a frame 12. 14 is a lead wire.

A ventilation hole 15 is provided on one side of the Radar mount 30, and a ventilation fan B is fixed to the periphery of the ventilation hole 15 with bolts 16 and nuts 17. In addition, a knob hole 24 is provided in the center of the rattle mount 30, and a terminal / control box is provided near the ventilation hole 15.
27 is installed.

The rattle body 7 is configured by mounting the opening / closing lid 19 inside the rattle frame 18, and is fixed to the periphery of the rattle mounting port.
On the front and rear sides of the rattle body 7, a rattle mount 6 and a rattle hood 8 are attached respectively.

The luminaire A includes a reflector 9 and a socket 10 on the luminaire main body 1.
And the lamp 3 are attached. One side of the burrs 20 forms a front surface portion 1a of the luminaire main body 1, and a shade 4 is fitted in a guide strip portion of an opening 6 provided in the front surface portion 1a.

22 is a filter attached to Ragari 20. Reference numeral 23 is a knob for operating the opening / closing lid 19 of the body 7, and opening / closing the opening / closing lid 19 by moving the knob 23 back and forth. The tip of the knob 23 projects from the knob holes 21 and 24. Knob 2
The base end of 3 is attached to a connecting member 28, and this connecting member 28 is connected to an opening / closing lid 19.

[Effect of device]

According to the shade mounting structure of the luminaire of the present invention, the lamp is exposed only by moving the shade upward, so that the lamp can be replaced and the reflector plate can be cleaned, and the lamp can be easily used with one hand. It has the effect of being exchangeable. In addition, since the shade is box-shaped, even if the lamp attached to the luminaire main body is large enough to protrude from the front of the luminaire main body, it can be housed inside the shade.

Further, since a cutout hole is formed in the lower surface of the shade, and a pair of locking portions that movably engage with a pair of guide strips of the lighting fixture body are formed on both side edges of the rear opening,
Even when the lamp is large as described above, since the lamp passes through the cutout hole, the shade can be moved in the vertical direction. Further, at this time, since the shade can be moved while grasping the peripheral portion of the cutout hole, there is an advantage that it is easy to handle.

Further, since the light of the lamp illuminates the lower part directly through the cutout hole, the foot becomes brighter, and the light is blocked by the peripheral portion of the cutout hole of the shade so that it is not dazzling even when approaching. Therefore, it is suitable for entrances and the like.

Further, since the guide strip portion is opened upward, the shade can be separated from the main body of the luminaire, and even in the separated state, the shade can be reliably gripped by the cutout hole, so there is no risk of falling.
