[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] like Figure 1 , Figure 2 As shown, the LED fire emergency indicator light is installed in a groove set on the surface of wall 1. The LED fire emergency indicator light includes:

[0029] Power supply box 4; Power supply box 4 is fixedly installed on the bottom of the groove. The power supply box 4 is equipped with a detection circuit and a storage battery. One end of the detection line of the detection circuit is connected to the mains power supply line 5, and the other end is connected to the storage battery. When the power supply line 5 supplies power, the current passes through the detection line to charge the storage battery. At this time, the storage battery is in a non-discharge state. When the power supply line 5 is interrupted, the detection circuit triggers the storage battery to discharge.

[0030] Bottom box 7; Bottom box 7 is a topless box body, and bottom box 7 is slidably set in the groove, with the bottom surface of bottom box 7 facing the bottom of the groove;

[0031] Arc-shaped light-emitting panel; the two ends of the arc-shaped light-emitting panel are fixedly connected to the top of the two sides of the bottom box 7, the outer convex surface of the arc-shaped light-emitting panel is set facing the groove opening, and the power line of the arc-shaped light-emitting panel passes through the bottom box 7 and is connected to the battery.

[0032] Electromagnetic device; The electromagnetic device is set in the groove. The electromagnetic device includes two ferromagnetic metal sheets 6 set on the bottom surface of the base box 7 and two electromagnets 2 set on the bottom of the groove. The electromagnets 2 are connected to the power supply line 5.

[0033] Two elastic devices are provided; one end of each elastic device is fixedly connected to the bottom of the groove, and the other end is fixedly connected to the bottom surface of the base box 7. When the power supply line 5 supplies power, the electromagnet 2 generates magnetic force, and the ferromagnetic metal sheet 6 is pressed and contacted with the electromagnet 2. The elastic device is in a compressed state, and the arc-shaped light-emitting plate is located inside the groove. When the power supply line 5 is de-energized, the battery supplies power to the arc-shaped light-emitting plate, the electromagnet 2 stops generating magnetic force, and the elastic device is in a released state. At this time, the arc-shaped light-emitting plate is located outside the groove.

[0034] In this embodiment, the arc-shaped light-emitting panel of this application is retractable. Compared with existing fire emergency indicator lights, this application uses an arc-shaped light-emitting panel as a lighting and information transmission carrier, which expands the information transmission range. When a fire accident occurs, escapers who are close to the wall or whose line of sight is parallel to the indicator surface can easily observe the information on the arc-shaped light-emitting panel. When the mains power is not disconnected, this application can be retracted into the wall 1 to reduce the space occupation. This application will only pop out when an accident occurs. After the mains power is turned on, the application can be reset by pressing it directly, which is convenient and quick.

[0035] Example 2

[0036] The difference between this embodiment and Embodiment 1 is that, as Figure 1 , Figure 2 As shown, an elastic device includes:

[0037] Positioning rod 3; the first end of positioning rod 3 is fixedly installed on the bottom of the groove, and the second end of positioning rod 3 passes through the bottom of the bottom box 7 and is set in the bottom box 7;

[0038] Limiting block; The limiting block is fixedly installed on the second end of the positioning rod 3;

[0039] Compression spring; The compression spring is fitted onto the positioning rod 3. The first end of the compression spring is fixedly connected to the bottom of the groove, and the second end of the compression spring is fixedly connected to the bottom of the base box 7. When the power supply line 5 supplies power, the compression spring is in a compressed state. When the power supply line 5 is de-energized, the compression spring is in a released state, and the limiting block is in contact with the inner bottom surface of the base box 7.

[0040] In this embodiment, the distance between the arc-shaped light-emitting plate and the groove opening is determined by the length of the positioning rod 3. It is generally set such that when the limiting block is pressed into contact with the inner bottom surface of the base box 7, both ends of the arc-shaped light-emitting plate and the groove opening are located on the same plane, which can reduce the occupation of external space while fully displaying the arc-shaped light-emitting plate.

[0041] Example 3

[0042] The difference between this embodiment and Embodiment 1 is that, as Figure 1 , Figure 2 As shown, the arc-shaped light-emitting plate includes:

[0043] Arc-shaped bottom shell 9; the two ends of the arc-shaped bottom shell 9 are fixedly connected to the top of the two sides of the bottom box 7. The arc-shaped bottom shell 9 has a hollowed-out direction indicator pattern. The outer convex surface of the arc-shaped bottom shell 9 is set towards the groove opening. The arc-shaped bottom shell 9 is made of green light-transmitting material.

[0044] Flexible LED strip 8; The flexible LED strip 8 is attached to the concave surface of the arc-shaped bottom shell 9. The power cord of the flexible LED strip 8 passes through the bottom box 7 and is connected to the battery. The light emitted by the flexible LED strip 8 is white light.

[0045] In this embodiment, the arc-shaped bottom shell 9 is provided with multiple hollowed-out indicator arrow patterns. Part of the light emitted by the flexible light strip is diffused outward through the hollowed-out indicator arrow patterns, while another part of the light passes through the arc-shaped bottom shell 9, serving as a green background color to prevent the escape personnel from having difficulty finding the pure white indicator light when there is interference from other light sources.

[0046] Example 4

[0047] The difference between this embodiment and Embodiment 1 is that the ferromagnetic metal sheet 6 is made of martensitic stainless steel. Martensitic stainless steel possesses magnetic properties while also exhibiting corrosion resistance and mechanical strength, thus increasing the service life of the electromagnetic device.
