Conventional examples are shown in FIGS. 4 and 5. That is, this lighting fixture has an opening/closing lid 31 provided on the back side of the ceiling of the fixture body 30, so that maintenance such as lamp replacement can be performed from behind the ceiling. 32 is the ceiling, 33 is the power line, 34 is the ballast, 35 is the reflective shade, 36 is the lamp socket, 3
7 is a panel frame, 38 is a panel, 39 is a spring for pulling up the panel, 40 is a hinge, 41 is a handle, and 42 is a fluorescent lamp.

恐れがあるなどの問題点があつた。 However, in the case of maintenance, when the opening/closing cover 31 is opened, dirt and dust from the ceiling enters into the fixture body 30 and accumulates on the panel 38, reducing the light efficiency and spoiling the aesthetics. There is a possibility that dust may fall into the room. Additionally, since the room could be viewed from behind the ceiling, there was a risk that confidential information and know-how could be leaked.

The lighting equipment of the present invention includes an equipment main body provided on the ceiling, an opening/closing lid provided on the back side of the ceiling of the equipment main body, and a shielding that shields an opening of the equipment main body in conjunction with the opening/closing operation of the opening/closing lid. It is equipped with means. When the opening/closing lid is opened, the shielding means closes the opening in the main body of the instrument, so it receives dust and
The room is blocked and cannot be seen from behind the ceiling.

In the figure, an opening/closing lid 2 is provided on the ceiling of the appliance body 1, a shaft 4 of a winding screen 3 serving as a shielding means is installed on one side of the opening 1a of the appliance body 1, and a winding spring 5 is installed. The screen 3 is wound up around the shaft 4. A pulley 6 is provided on the opposite side of the opening 1a and above the shaft 4,
6' is provided to connect the end 3a of the screen 3 and the opening/closing lid 2.
The opening/closing side 2a of the wire 7 is connected to the opening/closing side 2a of the

When opening/closing lid 2 is opened, the wire 7 is pulled out, the screen 3 is pulled out, and the opening 1a of the appliance body 1 is opened. The top surface of panel 9 is shielded. Therefore, the dust that enters the device when the lid 2 is opened accumulates on the screen 3 and is rolled up when the lid 2 is closed, resulting in a decrease in luminous flux due to the accumulation on the panel 9. There is no risk of falling into the room when the panel 9 is not present.
Further, in the open state, the screen 3 closes the opening 1a, so that the inside of the room cannot be seen and leakage of confidential information can be prevented.
第３図は閉状態であり、スクリーン３は巻取り
ばね５により巻取られ、開口部１ａは開き、併せ

通常の照明形態となる。 FIG. 3 shows the closed state, in which the screen 3 is wound up by the winding spring 5, the opening 1a is open, and the fluorescent lamp 12 is located on the top surface of the panel 9.
It becomes a normal lighting form.
この発明によれば、遮へい手段が開閉蓋の連動

According to this invention, since the shielding means shields the opening in conjunction with the opening/closing operation of the lid, there is an effect that dust does not fall into the panel or the room, and the inside of the room is not visible and confidentiality is maintained.
