Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a luminaire for a system ceiling, in which a luminaire is mounted inside a ceiling plate arranged on a ceiling using a T-bar.

[0002]

[Prior Art]

 Conventionally, in this type of system ceiling lighting fixture, it was necessary to separately provide a fixing frame for the panel to be installed on the lower surface of the reflector.

[0003]

[Problems to be solved by the device]

 In such a conventional lighting fixture for a system ceiling, a fixed frame for the panel to be installed on the ceiling surface must be separately provided. However, there is a drawback that the construction cost increases. According to the present invention, such drawbacks can be eliminated, the panel installed on the ceiling surface does not shake, does not drop in a stable state, and the lower surface of the reflector of the lighting fixture is open. Since there is no gap between the reflector and the T-bar when the lighting fixture is installed, the construction of the ceiling surface can be completed neatly at a low construction cost when the lighting fixture installation surface is viewed from below. It is an object of the present invention to provide a luminaire for a system ceiling.

[0004]

[Means for Solving the Problems]

 In view of the above problems, the present invention screw a mounting screw on the upper surface of the reflector of the lighting fixture installed inside the mounting bracket installed inside the ceiling plate, and attach the tip of the mounting screw. It is in contact with the inner surface of the mounting fixture, an elastic body is interposed between the upper surface of the reflector of the lighting fixture and the inner surface of the mounting fixture, and the lower edge of the reflector of the lighting fixture and the ceiling plate are mounted. The panel is interposed between the T-bar and the T-bar.

[0005]

[Action]

 Next, the operation of the present invention will be described. If you tighten the mounting screw that is screwed onto the upper surface of the reflector of the lighting fixture against the force of the elastic body, mount the lower edge of the reflector of the lighting fixture that has been in contact until now and the ceiling plate. A slight gap is formed between the edge of the receiving T-bar. When the mounting screws are loosened with the edge of the panel intervening in this gap, the spring force of the elastic body pushes the reflector of the lighting fixture downward, and the lower edge of the reflector of the lighting fixture The panel is clamped in the gap between the edge piece of the T-bar that carries the ceiling plate.

【Example】

 Embodiments of a system ceiling lighting device according to the present invention will be specifically described below with reference to the drawings. FIG. 1 is a sectional front view of a system ceiling lighting fixture according to the present invention showing a panel open state, and FIG. 2 is a system ceiling lighting fixture according to the present invention showing a panel mounted state. It is a cross-sectional front view.

A mounting screw 6 is screwed onto the upper surface of the reflection plate 4 of the luminaire 3 mounted inside the mounting bracket 2 installed inside the ceiling plate 1. The tip of the mounting screw 6 is brought into contact with the inner surface of the mounting member 2, and an elastic body 7 is interposed between the upper surface of the reflection plate 4 of the lighting fixture 3 and the inner surface of the mounting member 2. The panel 10 is interposed in the gap d between the lower edge 5 of the reflector 4 of the lighting fixture 3 and the edge piece 9 of the T-bar 8 on which the ceiling plate 1 is mounted. The ceiling plate 1 is placed on the other edge piece 9'of the T-bar 8 to form a system ceiling over the entire ceiling.

Next, how to dispose the panel 10 on the ceiling surface as a part of the system ceiling will be described. When the panel 10 as shown in FIG. 1 is opened and the mounting screw 6 screwed on the upper surface of the reflection plate 4 of the lighting fixture 3 is tightened against the force of the elastic body 7, the contact state has been reached until now. A slight gap d is formed between the lower edge 5 of the reflecting plate 4 of the lighting fixture 3 and the edge piece 9 of the T-bar 8 on which the ceiling plate 1 is mounted. When the edge of the panel 10 is inserted into the gap d and the mounting screw 6 is loosened, the spring force of the elastic body 7 causes the reflection plate 4 of the lighting fixture 3 to be pressed downward. In this state, as shown in FIG. 2, the panel 10 is inserted between the lower edge 5 of the reflector 4 of the lighting fixture 3 and the edge piece 9 of the T-bar 8 on which the ceiling plate 1 is mounted. The panel 10 is held on the ceiling surface by being sandwiched between the panels.

[0009]

[Effect of the device]

 Since the system ceiling lighting fixture according to the present invention has the above-mentioned configuration, it has the following effects. That is, when the panel is opened, the lower edge of the reflector of the lighting fixture is in contact with the edge of the T-bar supporting the ceiling plate due to the elastic force of the elastic body. On the other hand, the reflector can be mounted vertically without any gaps, and since the reflector is fixed with mounting screws, it does not move laterally and the lighting fixture can be stabilized inside the ceiling panel. It can be installed. Also, due to the elasticity of the entire reflector and the spring force of the elastic body interposed between the upper surface of the reflector of the lighting fixture and the inner surface of the mounting bracket, the panel is pressed from above. The panel has features such as being securely installed and not rising.
