[0041] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0042] As Figures 1 to 10 shown, a lighting fixture includes a flat panel lamp 10, a cooling mechanism 20, a purification mechanism 30 and a fire protection mechanism 40, wherein,

[0043] The cooling mechanism 20 is arranged above the flat panel lamp 10 and includes an air outlet pipe 201 and a semiconductor refrigeration chip 203;

[0044] The purification mechanism 30 is arranged below the air outlet pipe 201 and includes a purification pipe 301, an activated carbon filter 304, a thermosensitive glass tube I 305 and a compression spring I 306. The activated carbon filter 304 extends inside the purification pipe 301 through the thermosensitive glass tube I 305;

[0045] The fire protection mechanism 40 is symmetrically arranged on the front and rear sides of the air outlet pipe 201 and includes a fire extinguishing tank 406, a thermosensitive glass tube II 409 and a compression spring II 410. The fire extinguishing tank 406 is horizontally supported beside the air outlet pipe 201 through the thermosensitive glass tube II 409;

[0046] At normal temperature, the flat panel lamp 10 illuminates the area below it, the air entering the purification pipe 301 is filtered by the activated carbon filter 304, the air entering the outlet pipe 201 is cooled by the semiconductor cooling sheet 203, and the purified cold air is blown to the area below the flat panel lamp 10 through the outlet port 201c on the outlet pipe 201;

[0047] Under high temperature environment, both the thermosensitive glass tube 1 305 and the thermosensitive glass tube 2 409 automatically break, and the activated carbon filter 304 shrinks to the inner side of the purification tube 301 under the action of the compression spring 1 306. The fire extinguisher tank 406 introduces the fire extinguishing agent into the inner side of the outlet pipe 201 under the action of the compression spring 2 410, and the fire extinguishing agent is sprinkled to the lower area of ​​the flat lamp 10 through the outlet port 201c on the outlet pipe 201.

[0048] In this embodiment, the air outlet pipes 201 are provided with a plurality of them and are neatly arranged together. The air outlet pipe 201 is a "冂"-shaped structure and a mounting groove 201a is provided in the center of the top surface thereof. A heat insulation board 202 is embedded in the mounting groove 201a, and a semiconductor refrigeration plate 203 is embedded in the center of the heat insulation board 202. The top surface of the semiconductor refrigeration plate 203 is in contact with a heat sink 204 through thermal conductive silicone grease, and a silent fan 1 205 is installed on the upper side of the heat sink 204. The bottom surface of the semiconductor refrigeration plate 203 is in contact with a cooling plate 208 through thermal conductive silicone grease, and a silent fan 2 209 is installed on the lower side of the cooling plate 208. The air outlet pipe 201 is provided with an air inlet 201b directly below the mounting groove 201a, and the silent fan 2 209 is embedded in the air inlet 201b. Air outlets 201c are symmetrically distributed at both ends of the air outlet pipe 201. The top surface of the semiconductor cooling sheet 203 is the hot end and when it is hot, it transfers the heat to the heat sink 204, and then the silent fan 205 inhales the air and (when flowing through the heat sink 204) carries away the heat on the heat sink 204, thereby obtaining hot air and discharging it to the outside; the bottom surface of the semiconductor cooling sheet 203 is the cold end and when it is cold, it transfers the cold to the cooling plate 208, and then the silent fan 209 inhales the air and (when flowing through the cooling plate 208) carries away the cold on the cooling plate 208, thereby obtaining cold air and blowing it to the lower area of ​​the flat panel lamp 10 through the air outlet 201c.

[0049] In this embodiment, an air collecting pipe 206 is provided above all the air outlet pipes 201, a row of air collecting ports 206a are evenly distributed on the bottom surface of the air collecting pipe 206, the silent fan 209 is correspondingly installed at each air collecting port 206a, a pair of exhaust ports 206b are symmetrically distributed at both ends of the air collecting pipe 206, and the exhaust ports 206b are connected to exhaust pipes 207. The heat emitted by all the semiconductor cooling sheets 203 can be collected by the air collecting pipe 206 and discharged to the outside through the exhaust pipe 207.

[0050] In this embodiment, a pair of air inlets 301b are symmetrically distributed at both ends of the purification pipe 301. A pair of fixed frames 302 are symmetrically connected to the inner sides of the air inlets 301b of the purification pipe 301. This pair of fixed frames 302 are in an "E" shape structure and a pair of activated carbon filters 304 are hinged in the middle thereof. The first thermosensitive glass tube 305 and the first compression spring 306 are coaxially distributed and are both connected between the fixed frame 302 and the activated carbon filter 304. Through the first thermosensitive glass tube 305, this pair of activated carbon filters 304 can be extended in the purification pipe 301 in a "C" shape to obtain the maximum filtration area, thereby achieving the expected filtration efficiency and filtration effect. When the first thermosensitive glass tube 305 is heated and broken, through the first compression spring 306, this pair of activated carbon filters can be stacked in an "=" shape in the purification pipe 301 to obtain the maximum gas flow cross-section, thereby reducing the blocking effect on the gas and achieving the expected dispersion (fire extinguishing agent) effect.

[0051] In this embodiment, the purification pipe 301 is arranged below all the air outlet pipes 201. A row of air distribution ports 301a are evenly distributed on the top surface of the purification pipe 301. The second silent fan 209 is correspondingly installed at each air distribution port 301a. Through the second silent fan 209, the purified air in the purification pipe 301 can be conveyed to the air outlet pipe 201.

[0052] In this embodiment, an ultraviolet lamp tube 303 is installed in the middle of this pair of fixed frames 302, and a nanoscale titanium dioxide thin film is coated on this pair of activated carbon filters 304. The ultraviolet lamp tube 303 emits ultraviolet rays and irradiates the surface of the titanium dioxide, and the strongly oxidizing free radicals generated by the titanium dioxide under the illumination condition are used to decompose the harmful substances in the air entering the purification pipe 301.

[0053] In this embodiment, a gas guide bowl 402 is coaxially distributed at the outlet of the fire extinguishing tank 406. A gas guide pipe 403 is coaxially welded at the center of the gas guide bowl 402, and a gas guide hopper 404 is coaxially connected to the inner end of the gas guide pipe 403. A pair of connecting hoops 407 are connected to the outside of the fire extinguishing tank 406 through long bolts 408. The second heat-sensitive glass tube 409 and the second compression spring 410 are coaxially distributed and are both connected between the connecting hoop 407 and the gas guide bowl 402. The outer end of the gas guide pipe 403 communicates with the inner side of the air outlet pipe 201 through a shunt pipe 411. Through this pair of second heat-sensitive glass tubes 409, the fire extinguishing tank 406 and the gas guide bowl 402 can be kept coaxially distributed, thereby ensuring that the outlet of the fire extinguishing tank 406 is directly opposite the gas guide hopper 404 on the gas guide pipe 403. When the second heat-sensitive glass tube 409 is heated and broken, the outlet of the fire extinguishing tank 406 can be accurately inserted into the gas guide hopper 404 through the second compression spring 410. When the two are squeezed, the fire extinguishing agent in the fire extinguishing tank 406 is introduced into the gas guide pipe 403, and then introduced into the air outlet pipe 201 through the shunt pipe 411. The cold air carries the fire extinguishing agent and blows towards the lower area of the flat lamp 10 through the air outlet 201c.

[0054] In this embodiment, a T-shaped support plate 401 is screwed to the outside of the gas guide bowl 402. Through the support plate 401, the fire extinguishing tank 406 can be horizontally installed on the upper side of the integrated ceiling 50.

[0055] In this embodiment, a rubber pad 405 is adhesively pasted on the inner side of the gas guide hopper 404. Through the rubber pad 405, the sealing effect when the outlet of the fire extinguishing tank 406 is inserted into the gas guide hopper 404 can be ensured, and the fire extinguishing agent is prevented from spraying above the integrated ceiling 50.

[0056] The working principle of this lighting fixture:

[0057] (1) At normal temperature, the area below is illuminated by the flat lamp 10. The air entering the purification pipe 301 is filtered by the activated carbon filter screen 304, and the air entering the air outlet pipe 201 is cooled by the semiconductor refrigeration sheet 203. The purified cold air blows towards the area below the flat lamp 10 through the air outlet 201c on the air outlet pipe 201, so as to achieve the purpose of air cooling the area below.

[0058] (2) In a high-temperature environment, both the first heat-sensitive glass tube 305 and the second heat-sensitive glass tube 409 are automatically broken. The activated carbon filter screen 304 contracts inside the purification pipe 301 under the action of the first compression spring 306. The fire extinguishing tank 406 introduces the fire extinguishing agent into the inner side of the air outlet pipe 201 under the action of the second compression spring 410. The fire extinguishing agent is scattered towards the area below the flat lamp 10 through the air outlet 201c on the air outlet pipe 201, so as to achieve the purpose of extinguishing the fire in the area below.
