AI Technical Summary
Conventional flip-type fire emergency lights suffer from reduced light transmittance and brightness uniformity in the illuminated area due to the high-temperature pyrolysis of suspended matter on the lamp cover surface during a fire, thus affecting their safety guidance effectiveness.
Using an electric actuator, air chamber, one-way air inlet valve, and one-way air outlet valve, it cleans impurities from the lampshade surface with compressed air and emits an alarm sound through a whistle inside the air pipe to alert personnel.
Maintaining the light transmittance of the lampshade and the uniformity of brightness in the illuminated area enhances the safety and efficiency of emergency evacuation during fires.

Abstract
Claims
1. A flip-top type fire emergency lighting fixture, comprising an emergency lighting fixture structure (1), consisting of a light box (11), a flip-top plate, a lighting fixture assembly (14), and connecting parts, characterized in that: The interior of the light box (11) is provided with an air chamber (111), and an electric actuator (12) is provided below the air chamber (111) inside the light box (11). The air chamber (111) inside the light box (11) has an air inlet channel (112) extending outward from the upper side of the electric actuator (12) to penetrate the body of the light box (11). The upper end of the air chamber (111) has a through hole extending upward through the body of the light box (11), and a device is installed at the port of the through hole. There is a one-way air valve (114) that opens upwards in one direction. The upper surface of the lamp box (11) is covered by an air pipe (13) at the installation position of the one-way air valve (114). The upper end of the air pipe (13) is fitted with a connector facing the lamp cover of the lamp assembly (14) and has two pressurized nozzles (131). A whistle (132) that emits an alarm whistle after being blown is inserted and fixed in the through hole at the upper end of the air pipe (13).
2. A flip cover type fire emergency luminaire according to claim 1, characterized in that: The light box (11) is made of a sturdy material and has the ability to resist pressure and impact, which can protect the internal components. The lighting assembly (14) is connected to the light box (11) with the connecting parts, and the lighting assembly (14) is electrically connected to the electrical control module inside the light box (11) through the circuit.
3. The emergency cover fire lamp of claim 1, wherein: The output end of the electric push rod (12) is inserted into the interior of the air chamber (111) and fixed with the piston located below the air chamber (111) by a sliding seal. The lower end of the electric push rod (12) is electrically connected to the electrical control module inside the lamp box (11) with the connecting seat.
4. The cover-type fire emergency luminaire according to claim 1, characterized in that: The air intake duct (112) is equipped with a one-way air intake valve (113) that opens one-way into the air chamber (111).
5. The flip cover type fire emergency luminaire according to claim 1, characterized in that: The one-way vent valve (114) is located between the two lamp assemblies (14).
6. The cover emergency light fixture of claim 1, wherein: The air tube (13) is composed of a high-strength upper rigid tube and a high-strength lower flexible tube. The upper rigid tube is fixed to the lamp assembly (14) with an integrally set support rod on both sides near the lamp assembly (14).
7. The cover emergency light fixture of claim 1, wherein: The whistle (132) is sealed and inserted in a through hole with a diameter smaller than that of the air pipe (13) and the booster nozzle (131).
