Description

[Detailed Description of the Invention] The present invention relates to an improved structure of a lighting fixture in which the fixture body is directly attached to a ceiling surface.

In general, the ceiling surface is not only a flat surface, but also has ridges and protrusions.

For example, Figure 1 A is a ceiling with a rod edge, and the opening is a ceiling using wire wire.
There is a ceiling with a recessed ceiling hook.

When installing lighting equipment on a ceiling surface that has cutting ridges or protrusions, the ridges or protrusions are used to install the lighting equipment, which creates a gap between the lighting equipment and the ceiling surface, which makes it difficult to operate the flashing switch after the lighting equipment is installed. There are disadvantages such as the occurrence of shaking of the instrument, the occurrence of shaking of the instrument due to the vibration of the base and external force, the difficulty in installing the instrument horizontally, and the generation of noise due to resonance.

The present invention has been devised to eliminate such drawbacks, and one embodiment will be described below with reference to FIGS. 2 to 4.

Reference numeral 1 is a device body made by bending the periphery of a plate to form an inverted dish shape, on which lamps, lighting parts, flashing switches, etc. are attached.

2 is a translucent shade that covers the device body 1; 3, 3...
. . are screw holes drilled in the four corners of the main body 1, and recesses 4 are formed on the back surface of the main body around the screw holes.

5, 5... is an adjustment rod consisting of a screw screw that is screwed into the screw holes 3, 3... from the front side, and the head 5a is rotated by hand with the screwdriver insertion groove. The knurling is engraved so that it can be used.

Further, the distal end protruding from the back side is provided with a protrusion 5b for preventing removal, and this adjustment rod 5 can move forward and backward in the front and back directions of the main body.

Then, attach the center part of the device body 1 to the rod edge 7 of the ceiling 6 with a screw 8.
The instrument body 1 is stopped and attached to the ceiling, and then the adjustment rod 5 is advanced to bring the tip protrusion 5b into contact with the ceiling surface, thereby preventing the instrument body 1 from swinging.

On the other hand, when installing on a flat ceiling surface with no protrusions such as rod edges on the ceiling surface, after retracting the adjustment rod 5 as much as possible and positioning the tip protrusion 5b in the recess 4, the entire back surface of the main body is covered as shown in Fig. 4. Since the present invention is as described above, the main body of the appliance can be easily installed even on a ceiling surface with ridges or protrusions, and because of these protrusions, the main body and the ceiling surface Even if a gap is created between the device and the device, the gap can be filled by moving the adjustment rod back and forth, thereby preventing swinging of the device body and facilitating horizontal installation.

[Brief explanation of the drawing]

Figure 1 shows different aspects of the ceiling surface on which the main body of the lighting equipment is attached. Figure 2 is a perspective view of the main part of the device of the present invention installed on the ceiling shown in Figure 1A, Figure 3 is a sectional view of the main part of Figure 2, and Figure 4 is the device of the invention installed on a different ceiling surface. It is a sectional view of the main part of the main body. 1... Instrument body, 5... Adjustment rod, 4.
