DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluorescent lamp apparatus which does not require support from a concrete floor on an upper floor and can be directly mounted on a ceiling board and mounted.

[0002]

2. Description of the Related Art A conventional embedded fluorescent lamp used in general office buildings, schools, commercial facilities, etc., comprises a main body, a reflector, a decorative frame, a stabilizer, a socket, wiring materials, and a fluorescent lamp. Even a basic 40w1 fluorescent light fixture weighs more than 5 kg.

When the fluorescent lamp is mounted on a general ceiling such as a base board or a finishing material, the weight of the fluorescent lamp itself is heavy. It can't support the weight and breaks.

[0004] Therefore, the fluorescent lamp fixture is suspended from the concrete floor on the upper floor with a dedicated metal fitting so that the weight of the fluorescent lamp fixture itself does not affect the ceiling board.

[0005] In this construction procedure, first, the position of the fluorescent light fixture is determined, and a special fitting is buried in the concrete at the time of placing concrete on the upper floor. After the concrete floor is completed, the hanging rod is lowered using the buried special fittings. Two hanging rods are required for one fluorescent lamp fixture. After making the ceiling, drill the necessary mounting holes in the ceiling, align the position of the hanging rod with the position of the hanging rod receiving port of the fluorescent light fixture,
The fluorescent lamp fixture was fixed to the hanging rod, and the installation of the fluorescent lamp fixture was completed.

[0006]

Originally, when deciding the arrangement of fluorescent lamp fixtures, it is better to determine the best position in consideration of detailed requirements after the shape of the room after concrete casting is determined. I can do it. However, special fittings for fluorescent lamps embedded in concrete floors require that the positions of the fluorescent lamp fixtures be determined before concrete is cast. This inconsistency has not yet been resolved. Frequent changes in the position of fluorescent lighting fixtures after casting concrete. For this reason, there has been a problem that the work required to attach the special fittings and the hanging rods buried in the concrete floor and the mounting thereof is often wasted. In addition, the special fittings for fluorescent lamps had to be placed by working upwards at a high place before placing concrete, and it was necessary to ensure safety. The present invention has been made in view of the above circumstances, and provides a fluorescent lamp fixture that can eliminate the need for special fittings and hanging bars embedded in concrete, shortening the fluorescent lamp fixture installation work, reducing the construction cost, and reducing construction safety. It aims at improvement.

[0007]

In order to achieve the above-mentioned object, it is only necessary to eliminate the work related to the fluorescent lamp apparatus before the concrete is cast. In this case, the fluorescent lamp device cannot be hung from the concrete floor on the upper floor with the hanging rod. Therefore, a fluorescent lamp device that does not need to be hung is considered. Reduce the weight of the fluorescent lighting fixture so that the ceiling board is not broken even if the fluorescent lighting fixture is directly mounted on the ceiling board. That is, it is a lightweight fluorescent lighting device. For this reason, the ballast is first placed separately,
The main body is omitted, for example, by applying the structural strength of the main body to the decorative frame. Since the reflection plate does not need to be made of a steel plate, it is changed to, for example, paper having light weight and rigidity.

[0008] That is, the structure of the fluorescent lamp fixture according to the present invention for achieving the above object is a fluorescent lamp fixture mounted and mounted on a ceiling board stretched on a lightweight ceiling foundation, the longitudinal direction of which is a fluorescent lamp. A rectangular decorative frame having a length substantially the same as that of the decorative frame, a pair of parallel side decorative panels provided on a pair of opposite short sides of the decorative frame, and at least one pair provided on an opposing surface of the pair of side decorative panels. A fluorescent lamp socket, a reflective paper attached between the pair of side decorative panels and covering a fluorescent lamp mounted above the pair of fluorescent lamp sockets with a gap therebetween, and the decorative frame in a mounting hole formed in the ceiling board. A ballast that locks the lighting device, a ballast attached to the hanging bolts on the lightweight ceiling base, and supplies lighting power to the fixture-side lighting circuit to which the fluorescent lamp socket is connected, the fixture-side lighting circuit, and the ballast To connect and disconnect Characterized by comprising a stationary electrical connector.

In this fluorescent lamp apparatus, the entire apparatus is reduced in weight and can be directly mounted on the ceiling board and mounted. Determination of the arrangement before concrete casting, embedding of special fittings on the concrete floor, and embedding of the special metal fittings are performed. The work of lowering the hanging rod to the special fitting and the work of fixing the hanging rod and the fluorescent light fixture are all unnecessary. In addition, the timing of determining the arrangement of the fluorescent lamp fixtures can be determined after the shape of the room after the concrete is cast.

[0010] Further, in the fluorescent lamp device according to the present invention, the short side portion may be so set that the side decorative plate stands upright with respect to the rectangular decorative frame and can be folded in parallel with the decorative frame. Characterized by being rotatably mounted via a hinge.

In this fluorescent lamp apparatus, the side decorative panel is rotatably attached to the decorative frame via the hinge, and the side panel is folded in parallel with the decorative frame, so that the entire apparatus has a thin and compact shape. .
