Description

[Detailed description of the invention] This invention relates to a lighting fixture with a ventilation inlet that has a ventilation function, and its main purpose is to make the appearance beautiful by preventing dirt adhering to the vicinity of the inlet from becoming noticeable. To provide a lighting fixture with a ventilation inlet that can be maintained.

Conventionally, in this type of lighting equipment, as shown in FIGS. 1 to 3, the suction port 20 opens at the lower surface of the ceiling 21 and is exposed indoors, so that dirt in the air drawn into the suction port 20 is removed. d adheres to the ceiling 21 and the suction port cover 22 near the suction port 20, resulting in an unsightly appearance.

The present invention has been devised in view of the above points, and will be described in detail below based on the embodiments shown in the figures.

The housing 1 is formed into a flat disk shape with a hollow interior, and the interior is divided into upper and lower parts by a partition plate 2.
A lamp 5 is housed in the lower chamber 3.

A plurality of suction ports 6 are perforated concentrically in the upper surface of the housing 1, that is, in the portion covering the upper chamber 4.

The arm tube 7 is formed into a cylindrical shape with an enlarged diameter at the top and an open top and bottom, and the lower end is continuous with the center of the upper surface of the housing 1 and communicates with the upper chamber 4, and the upper end is fixed to the lower surface of the ceiling 8 with screws 14. The housing 1 is suspended from the ceiling 8.

The ventilation chamber 9 is arranged in the ceiling directly above the housing 1, and has an opening 10 on the lower surface exposed to the ceiling 8, and this opening 10
is closed with the upper part of the arm tube 7 to make the ventilation chamber 9 communicate with the arm tube 7 and the upper chamber 4.

A fan 11 is provided in the ventilation room 9, and this fan 1
1, the dirty air in the room is sucked in through the suction port 6 and is discharged outside through the duct 12 arranged in the ceiling.

Here, the upper end of the arm tube 7 is in close contact with the ceiling 8 with a gasket 13 to prevent air leakage.

As described above, in the present invention, since the suction port 6 is provided in an out-of-sight location such as the upper surface of the housing 1 and at a location away from the ceiling 8, the amount of air contained in the inhaled air is Dirt only adheres to the top surface of the housing 1 near the suction port 6, and the 8,000 surfaces of the ceiling are not soiled. Therefore, dirt can be hidden from view from below, and the appearance can be maintained beautifully. Since the housing 1 containing the lamp 5 is provided with the suction port 6, heat from the lamp 5 can be radiated by air passing through the suction port 6, and the heat radiation effect can be enhanced.
