Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a lighting fixture whose lamps can be replaced from the ceiling, and particularly to a fixture which improves the workability and safety of lamp replacement in high ceilings.

[Background of the invention]

In the case of ceiling-mounted lighting equipment, for example, when the lighting equipment is used on a high ceiling, maintenance work such as lamp replacement and cleaning must be performed at heights, which is dangerous. In order to improve safety, scaffolding such as a rolling tower is required, which increases running costs. Therefore, as a safe and economical way to replace the lamp, there is a method of replacing the lamp from behind the ceiling. but,
In the conventional ceiling lamp replacement method, for example, as shown in FIGS. 3 and 4, a part of the reflector 22 on the back side of the lamp 6 is configured as an opening/closing lid 3, and when the opening/closing lid 3 is opened, The lamp 6 was also supported on the appliance main body 1 side. In addition,
4 is a ballast, 5 is a socket, 7 is a ceiling material, and 10 is a handle.

The lamp replacement work for lighting fixtures with this type of configuration is as follows:
Since the replacement work is performed with the lamp 6 placed inside the fixture body 1, it is difficult to see how it is installed, and there is a possibility that the lamp 6 may hit various places after being removed and before being taken out into the ceiling. , which could lead to a fall accident.

[Purpose of the invention]

An object of the present invention is to provide a lighting fixture in which the lamp is replaced from the ceiling, which improves the work efficiency of replacing the lamp and has safety by preventing the lamp from falling. There is a particular thing.

[Summary of the invention]

The features of the present invention are that the socket is fixed to the opening/closing lid, the opening/closing lid socket and the lamp are integrated, and the whole can be opened and closed. According to this method, the lamp and socket are exposed outside the fixture, so that lamp replacement work can be carried out efficiently and with reliable pressure.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. 1st
In FIGS. 2 and 2, the main body 1 of the apparatus is constructed by integrating a side reflector 2 with an end plate 11, housing a stabilizer 4 in the center, and is fixed to a ceiling material 7 with a hanging bolt 8. The socket 5 is fixed to the opening/closing lid 3 which also serves as a top reflector,
Furthermore, a lamp 6 is supported. The opening/closing lid 3 and the instrument main body 1 are engaged by a rotating shaft 9, and can be easily opened and closed using a handle 10Vc.

The electrical connection between the ballast 4 and the socket 5 in the appliance body 1 is made on the back side of the appliance body 1, and the wiring is done so that no unreasonable tension is applied to the electric wire due to the movement of the opening/closing lid 3. The opening/closing lid 3 consists of a top reflecting plate 31 and a lid plate 32 which serves both to protect the wiring section and to reinforce the entire structure. In addition, the instrument body 1
A receiving portion 21 for the opening/closing lid 3 is provided on the upper edge of the side reflecting plate 2 constituting the main body.

The stabilizer 4 is provided at the center of the instrument body 1, and is surrounded by a side reflector 2 provided at the center. A hanging bolt 8 for supporting the fixture main body 1 is provided in the center, and the lighting fixture can be effectively supported.

Although not shown, it is possible to securely support the weight by locking both ends of the appliance main body 1 to a frame member such as a T-bar that supports the ceiling frame 7.

Of course, you can replace the Run 1 Pro in a lighting fixture with this type of configuration from the bottom. For example, if you are in a room with a high ceiling and maintenance from the bottom is difficult, create a space under the ceiling,
Furthermore, by forming a passage along the lighting equipment, it becomes possible to replace lamps from the ceiling. That is, as shown in the figure, the lid 3 is opened using the handle 10, and the lamp 6 attached to the lid 3 can be replaced or cleaned.

〔Effect of the invention〕

In this way, according to the present invention, the socket, lamp, and opening/closing lid can be integrated and exposed outside the appliance.
To easily and reliably remove and install a lamp in lamp replacement work in a restricted work space such as the ceiling. Another advantage is that the installation status of the lamp can be visually confirmed, allowing for highly reliable work.
