Through the setting of the filter screen 86, dust can be effectively prevented from entering the space formed by the rear shell 1 and the limiting front shell 2 through the air inlet 82, effectively preventing dust from accumulating on the lighting fixture 53.

[0047] Refer to the attached Figure 1 — Figure 9 As shown, the working principle of the present utility model is as follows:

[0048] When a power outage occurs and lighting is required from the lighting fixture, the circuits of the first electromagnet 55, the second electromagnet 74, and the third electromagnet 75 connected to the outside are powered off. At this time, all the electromagnets lose their magnetism, and the dust-proof plate 71 moves downward under the action of gravity and the elastic force of the assisting spring 734. At the same time, when the first electromagnet 55 is powered off, the telescopic spring 543 pushes the moving part 52 to move through its elastic force, driving the lighting fixture 53 on the moving part 52 to move outward. At the same time, the storage battery 4 provides electrical energy for the lighting fixture 53 and the emergency indicator board 6, enabling the lighting fixture and the emergency indicator board 6 to emit light for lighting and indication.

[0049] When the power is restored, the first electromagnet 55, the second electromagnet 74, and the third electromagnet 75 are powered on to generate magnetic force. After the first electromagnet 55 is powered on, it magnetically attracts the moving part 52, and the moving part 52 drives the lighting fixture 53 to move, causing the lighting fixture 53 to contract. At the same time, when the second electromagnet 74 and the third electromagnet 75 are powered on, the second electromagnet 74 magnetically attracts the magnetic conduction block 736 on the control board 72, and the magnetic conduction block 736 drives the control board 72 to move upward. When the magnetic conduction block 736 is attracted to the second electromagnet 74, the control board 72 also rises to the designated position. The magnetic force between the third electromagnet 75 and the control board 72 drives the control board 72 to move upward and compresses the assisting spring 734, slowing down the rising speed of the control board 72 to ensure that there is enough time for the lighting fixture 53 to contract and hide.

[0050] The above embodiments are descriptions of this application, not limitations on this application. Any simple transformation of this application also belongs to the protection scope of this application.
