Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an embedded lighting fixture that is attached to a ceiling surface or the like in a room.

[0002]

[Prior Art]

 There are various types of lighting fixtures placed on the ceiling in the room, such as hanging type, embedded type, and direct mounting type, but when you prefer a simple atmosphere in your room or when the ceiling height is not very high. In most cases, the embedded type is adopted. Since embedded lighting fixtures dislike heat generation, fluorescent lamps are mostly used.

[0003]

[Problems to be solved by the device]

 However, in embedded lighting fixtures using fluorescent lamps, the seal inside the fixture tends to be incomplete. In particular, it is complicated to complete the seal between the ballast case and the embedding box, which is installed inside the embedding box for mounting the fluorescent lamp body, and there is much air circulation in this part. This phenomenon is extremely disliked in cold regions because it affects the heating effect, but it requires time-consuming processing during construction, and is difficult to find after construction, so it is overlooked in an incomplete state. There are many things. In rare cases, the cover that should be attached to the ballast case is postponed because the installation is troublesome, and at last I forget to install it, and the heat insulating material in the ceiling above the ball will come into contact with the ballast, causing a dangerous situation. In some cases, you may be invited. The present invention is an embedded type that can easily attach a ballast case to an embedded box for mounting a fluorescent lamp body, can easily seal the ballast case, and does not forget to attach the ballast case cover. It is intended to provide a lighting fixture.

[0004]

[Means for Solving the Problems]

 The embedded luminaire according to the present invention comprises an embedded box for mounting a fluorescent lamp body, which is inserted into a quadrangular mounting hole provided on a wall surface of the embedded box from the inside of the embedded box, and is externally mounted. An embedded luminaire with a ballast case that projects and fixes, the ballast case having an integral structure in which a cover is coupled to a case substrate, and a quadrilateral flange for the mounting hole, Further, an auxiliary flange is arranged on a part of the quadrangle of the above-mentioned flange to form a double flange portion that contacts the inner and outer surfaces of the mounting hole.

[0005]

[Action]

 The double flange part of the quadrilateral of the ballast case flange has its mounting position determined by sandwiching the inner and outer surfaces on the side of the mounting hole that is in contact with it. The ballast case can be fixed in the mounting hole by screwing. Since the ballast case has an integral structure in which the cover is joined to the case substrate, the cover cannot be separated.

【Example】

 1 is a vertical sectional view showing an embodiment of the embedded luminaire of the present invention, FIG. 2 is an enlarged vertical sectional view of an essential part of FIG. 1, and FIG. 3 is an enlarged perspective view of an essential part of FIG. In the figure, 1 is an embedded lighting fixture, 2 is a fluorescent lamp body of the embedded lighting fixture 1, 3 is also an embedded box, 31 is a mounting hole in the embedded box 3, 4 is a ceiling plate, and 5 is a fluorescent lamp. A ballast case for the body 2, 51 is a flange of the ballast case 5, 52 is a ballast body, 53 is a case substrate of the ballast 5, and 54 is also a cover. Further, 55 is an auxiliary flange outside a part of the flange 51, and 56 is also a double flange part. As shown in FIG. 1, in the embedded lighting fixture 1 of this embodiment, a wooden embedded box 3 is inserted into a ceiling plate 4 and placed in an embedded state. The lamp body 2 and one elongated ballast case 5 are attached and configured.

The ballast case 5 is provided with a mounting hole 31 on the side surface of the embedding box 3 where the outer circumference of the ballast case 5 is almost in contact, and is inserted into the mounting hole 31 from the inside. Therefore, as shown in FIGS. 2 and 3, there is provided a quadrilateral flange 51 projecting from the inner side surface of the ballast case 5 to the periphery. Three ballasts 52 are housed inside the ballast case 5, and the ballast case 5 has a steel plate cover 54 welded and fixed to an elongated quadrilateral steel plate case substrate 53 having the flange 51. Configure. The cover 54 is formed by bending an elongated quadrilateral steel plate into a substantially L shape along the longitudinal direction, and forming a welding flange having a narrow width also in a portion in contact with the case substrate 53. In this case, the ballast 52 is placed on the inner surface of the cover 54 and fixed by a screw penetrating from the outside of the cover 54.

An auxiliary flange 55 is disposed on the upper surface of the cover 54 so as to face a part of the quadrilateral flange 51, thereby forming a double flange portion 56. That is, with the upper side of the flange 51 as the above-mentioned part, an auxiliary flange 55 is provided in parallel with the upper side, and the distance between the flange 51 and the auxiliary flange 55 is made substantially equal to the thickness of the mounting hole 31 portion. More specifically, at the base of the flange 55, the spacing is the thickness of the mounting hole 31 plus the compression thickness of the sponge packing 57, and the outer end of the flange 55 is widened diagonally. Let it be a part 56. This is an arrangement for inserting the ballast case 5 into the mounting hole 31 from the inside of the embedding box 3 with the ballast case 5 in an oblique posture and applying the double flange portion 56 to the upper side of the mounting hole 31. Is.

Then, while inserting the ballast case 5, the surface of the flange 51 is gradually made vertical, and as shown in FIG. 2, the lower side of the flange 51 is brought into contact with the front surface of the mounting hole 31, and the lower side of the flange 51 is fixed with a wood screw 58. After fixing to the mounting hole 31, the mounting of the ballast case 5 is completed. The auxiliary flange 55 is formed to have a substantially L-shaped cross section, and is fixed to the upper surface of the cover 54 by welding. The sponge packing 57 is attached in advance over the entire circumference of the flange 51. The wiring 59 extending from the ballast 52 to each fluorescent lamp body 2 is passed through a wiring hole 60 provided in the vicinity of the end of the case substrate 53 and sealed by filling with a caulking agent.

The embedded luminaire 1 according to the present embodiment is configured as described above, and when the ballast case 5 is mounted, the case substrate 53 and the cover 54 are integrally combined, which is the same as the conventional one. It's safe because you don't forget to attach the separate cover to the ballast, and the stabilizer 52 does not touch the heat insulating material in the ceiling and cause a fire. Since the number of the fixing wood screws 58 of the stabilizer case 5 is almost halved and the tightening range is in the lower part, the work can be carried out easily and quickly. Further, the sponge packing 57 is also adhered to the seal of the surface of the flange 51, so that the seal is surely performed. Therefore, there is no adverse effect on the heating due to air leakage around the stabilizer case 5.

The embedded luminaire of the present invention can be modified in various ways other than the above embodiment. For example, the double flange portion can be simplified by using an intermittent type instead of the continuous type.

[0012]

[Effect of the device]

 According to the embedded luminaire of the present invention, the ballast case can be easily and surely attached to the embedded box, and the sealing can be easily performed, and the adverse effect on the heating due to the incomplete sealing of this portion can be prevented. Also, there is no risk of the ballast's cover coming into contact with the heat insulating material behind the ceiling because the ballast case is not forgotten.
