[0018] This application has at least the following beneficial effects:

[0019] The emergency lighting fixture provided in this application is fixedly installed onto a fixed body using an installation assembly. The installation assembly includes a fixed mounting structure and an adapter slider. The fixed mounting structure is fixedly installed onto the fixed body. The first connecting end of the adapter slider is detachably connected to the fixed mounting structure, and the second connecting end of the adapter slider is slidably connected to a groove in the housing of the lamp body. The drive circuit board and LED light source are both installed inside the housing of the lamp body and electrically connected.

In this way, the emergency lighting fixture is fixedly installed onto the fixed body using the installation assembly. When the emergency lighting fixture needs to be replaced, since the first connecting end of the adapter slider is detachably connected to the fixed mounting structure, workers only need to disassemble the first connecting end of the adapter slider from the fixed mounting structure to remove the adapter slider, lamp body, and light guide plate as a whole, without disassembling the fixed mounting structure, reducing disassembly workload and increasing disassembly efficiency. In the emergency lighting fixtures provided in the embodiments of this application, the adapter slider, lamp body, and light guide plate of the new emergency lighting fixture are pre-assembled as a single module. Therefore, workers only need to reconnect the first connecting end of the adapter slider of the new emergency lighting fixture to the fixed installation structure that has not been disassembled to complete the installation, reducing the intensity of installation work and increasing installation efficiency. When it is necessary to move and change the relative position of the emergency lighting fixture with respect to the fixed body, since the second connecting end of the adapter slider is slidably connected to the groove of the lamp body housing, workers only need to open the cover to release the sliding restriction of the cover on the adapter slider, and then slide the adapter slider along the groove to the predetermined relative position. After that, the cover is closed again to close the groove, thus completing the work of moving and changing the relative position of the emergency lighting fixture with respect to the fixed body, reducing the intensity of work and increasing adjustment efficiency.

[0038] An embodiment of this application provides an emergency lighting fixture suitable for installation on fixed surfaces such as ceilings, walls, and poles. The light guide plate 30 of the emergency lighting fixture faces the passageway, allowing people to easily and clearly observe the pre-set emergency markings on the light guide plate 30. The emergency lighting fixture includes a mounting assembly 10, a lamp body 20, and a light guide plate 30.

[0039] like Figures 1 to 6 As shown, the emergency lighting fixture provided in this embodiment is fixedly installed on the wall at the corner of the passage using the mounting assembly 10, and the surface of the light guide plate 30 of the emergency lighting fixture is parallel to the wall surface. The emergency markings preset on the light guide plate 30 can be clearly observed by people passing through the corner of the passage.

[0040] like Figure 7 As shown, the emergency lighting fixture provided in this embodiment is fixedly installed on the wall of a straight and long passageway via the mounting assembly 10, and the surface of the light guide plate 30 of the emergency lighting fixture is perpendicular to the wall surface. The emergency markings preset on the light guide plate 30 can be clearly observed by people passing through the straight and long passageway.

[0041] Among them, such as Figures 1 to 6 The emergency lighting fixtures shown are similar to those shown.Figure 7 The emergency lights shown all have the same structure, only their installation configurations differ, thus making them suitable for different emergency indication scenarios.

[0042] like Figure 8 As shown, the emergency lighting fixture provided in this embodiment is fixedly installed on the top of a low, straight, and long passageway wall via the mounting assembly 10, and the surface of the light guide plate 30 of the emergency lighting fixture is perpendicular to the low passageway or wall. Pre-set emergency markings on the light guide plate 30 can be clearly observed by passersby. For example, Figure 8 The emergency lighting fixtures shown are similar to those shown. Figures 1 to 7 The emergency lighting fixture shown differs in structure only from some components of the mounting assembly 10, while the rest of the structure is the same.

[0043] like Figure 9 As shown, the emergency lighting fixture provided in this embodiment is fixedly installed on a high ceiling via the mounting assembly 10. The lamp body 20 and the light guide plate 30 extend downwards to a suitable height via the mounting assembly 10. Furthermore, the front of the light guide plate 30 faces the passageway, making it easy for people to clearly observe the preset emergency markings on the light guide plate 30. For example... Figure 9 The emergency lighting fixtures shown are similar to those shown. Figures 1 to 8 The emergency lighting fixture shown differs in structure only from some components of the mounting assembly 10, while the rest of the structure is the same.

[0044] The following details the structural design and installation operation of the emergency lighting fixtures provided in the embodiments of this application.

[0045] like Figures 1 to 9 As shown, the mounting assembly 10 includes a fixed mounting structure 11 and an adapter slider 12. The fixed mounting structure 11 is used for fixed mounting to a fixed body. The adapter slider 12 has a first connecting end 121 and a second connecting end 122. The first connecting end 121 and the nut 13 form a detachable locking connection with the fixed mounting structure 11. The lamp body 20 includes a housing 21, a cover plate 22, a drive circuit board 23, and an LED light source 24. The housing 21 is formed by a first half-shell 201 and a second half-shell 202. The drive circuit board 23 and the LED light source 24 are both disposed inside the housing 21. The LED light source 24 is electrically connected to the drive circuit board 23. The housing 21 is provided with a sliding groove 211. The second connecting end 122 is slidably disposed in the sliding groove 211. Furthermore, the cover plate 22 is detachably fitted onto the opening of the sliding groove 211. The cover plate 22 is used to restrict the sliding of the adapter slider 12 relative to the housing 21. The light guide plate 30 is connected to the housing 21 and extends outside the housing 21. The light-incident end of the light guide plate 30 is directly opposite the LED light source 24.

[0046] The emergency lighting fixture provided in this application is fixedly installed on a fixed body using an installation assembly 10. The installation assembly 10 includes a fixed installation structure 11 and an adapter slider 12. The fixed installation structure 11 is fixedly installed on a wall. The first connecting end 121 of the adapter slider 12 is detachably connected to the fixed installation structure 11, and the second connecting end 122 of the adapter slider 12 is slidably connected to a groove 211 in the housing 21 of the lamp body 20. The drive circuit board 23 and the LED light source 24 are both installed inside the housing 21 of the lamp body 20 and electrically connected. A light guide plate 30 is connected to the housing 21 and extends to the outside, with the light-incident end of the light guide plate 30 facing the LED light source 24. The light emitted by the LED light source 24 is propagated and emitted through the light guide plate 30, thereby meeting the lighting requirements for emergency indication and making it easy for people to clearly see the preset emergency markings on the light guide plate 30. Thus, the emergency lighting fixture is fixedly installed on the fixed body using the installation assembly 10. When the emergency light fixture needs to be replaced, since the first connecting end 121 of the adapter slider 12 is detachably connected to the fixed mounting structure 11, the operator only needs to disassemble the first connecting end 121 of the adapter slider 12 from the fixed mounting structure 11 to remove the adapter slider 12, the lamp body 20, and the light guide plate 30 as a whole, without disassembling the fixed mounting structure 11, thus reducing the workload of disassembly and increasing the efficiency of disassembly. In the emergency light fixture provided in the embodiments of this application, the adapter slider 12, the lamp body 20, and the light guide plate 30 of the new emergency light fixture are pre-assembled as a whole module. Therefore, the operator only needs to reconnect the first connecting end 121 of the adapter slider 12 of the new emergency light fixture to the fixed mounting structure 11 that has not been disassembled to complete the installation, thus reducing the workload of installation and increasing the efficiency of installation. When it is necessary to move or change the relative position of the emergency light fixture with respect to the fixed body, since the second connecting end 122 of the adapter slider 12 is slidably connected to the groove 211 of the housing 21 of the lamp body 20, the operator only needs to open the cover plate 22 to release the sliding restriction of the cover plate 22 on the adapter slider 12, and then slide the adapter slider 12 along the groove 211 to the predetermined relative position. Then, the operator closes the cover plate 22 back into the groove 211, thus completing the work of moving or changing the relative position of the emergency light fixture with respect to the fixed body. For example, changing the installation state of the emergency light fixture from such to such a state. Figures 1 to 6 The installation state shown has been moved and changed to, for example Figure 7 The installation status shown reduces workload and increases adjustment efficiency.

[0047] In the emergency lighting fixtures provided in the embodiments of this application, such as Figure 2 , Figure 5 , Figures 7 to 9As shown, the cover plate 22 includes multiple sub-covers 221. The ends of two adjacent sub-covers 221 respectively abut against the two sides of the adapter slider 12 to restrict the sliding of the adapter slider 12 relative to the housing 21. This allows for simple and quick fixation of the relative position of the adapter slider 12 and the slide groove 211 of the housing 21, thereby efficiently completing the assembly and adjustment work.

[0048] When it is necessary to change the installation status of emergency lighting fixtures from such Figures 1 to 6 The installation state shown has been moved and changed to, for example Figure 7 In the installation state shown, the end wall of the slide groove 211 and the end of the adjacent sub-cover 221 respectively abut against both sides of the adapter slider 12 to restrict the sliding of the adapter slider 12 relative to the housing 21. This completes the movement and adjustment of the installation state of the emergency lighting fixture, which is simple and quick.

[0049] like Figure 2 , Figure 5 , Figures 7 to 9 As shown, in the emergency lighting fixture provided in the embodiments of this application, the adapter slider 12 is symmetrically arranged on both sides of the midpoint of the vertical slide groove 211. The shape of one end of the sub-cover 221 is adapted to the shape of one side of the adapter slider 12, and the shape of the other end of the sub-cover 221 is adapted to the shape of the end wall of the slide groove 211. Furthermore, the shape of the other side of the adapter slider 12 is adapted to the shape of the end wall of the slide groove 211. In this way, the adapter slider 12 has multiple adjustable positions relative to the slide groove 211, which can be adapted to the requirements of the actual use scenario of the emergency lighting fixture, which is simple, convenient and efficient.

[0050] like Figure 2 , Figure 5 , Figures 7 to 9 As shown, in the emergency lighting fixture provided in the embodiments of this application, hooks 222 are provided on both sides of the sub-cover 221 along the direction of extension of the vertical slide groove 211, and slots 212 are provided on both sides of the slide groove 211. The hooks 222 are hooked into the slots 212. The sub-cover 221 is assembled and stabilized in the groove of the slide groove 211 by hooking the hooks 222 into the slots 212. This installation method is not only simple and quick, but also easy to disassemble, which helps to improve the efficiency of installation or disassembly.

[0051] In the emergency lighting fixtures provided in the embodiments of this application, the adapter slider 12 is provided with a wiring channel 123, such as... Figure 6 As shown. The two ends of the wiring channel 123 are respectively connected to the first connection end 121 and the second connection end 122. The wiring channel 123 is used to carry the power lines of the drive circuit board 23. The power lines are hidden within the wiring channel 123, avoiding messy exposure and resulting in a clean and simple overall appearance for the emergency lighting fixture. Furthermore, the fixed installation structure 11 forms a receiving space 116.Figure 5 and Figure 6 As shown, the receiving space 116 is connected to the wiring channel 123, and the receiving space 116 is used to accommodate the power cord. The power cord is further concealed within the receiving space 116, avoiding messy exposure of the power cord and making the overall appearance of the emergency light fixture simple and clean.

[0052] In the emergency lighting fixture provided in the embodiments of this application, the fixed installation structure 11 includes a first mounting member 111 and a second mounting member 112. The first mounting member 111 is fixedly installed on the fixed body by screws. The second mounting member 112 is detachably connected to the first mounting member 111 and forms a receiving space 116. Furthermore, the first connecting end 121 is detachably connected to the second mounting member 112. When the emergency lighting fixture needs to be replaced, the worker removes the second mounting member 112 from the first mounting member 111. Then, the second mounting member 112, the adapter slider 12, the lamp body 20, and the light guide plate 30 can be removed as a whole. The worker does not need to be in a high-altitude working state for a long time. Then, the second mounting member 112 is detached from the second connecting end 122 of the adapter slider 12. On the ground, the second connecting end 122 of the adapter slider 12 of the new emergency lighting fixture is connected and fixed to the second mounting member 112. Finally, the second mounting member 112 is re-fixed to the first mounting member 111, thus completing the replacement work, reducing the workload and increasing the replacement efficiency.

[0053] In such Figure 2 , Figure 5 and Figure 7 In the illustrated emergency lighting fixture, the second mounting component 112 includes a first bracket 113 and a second bracket 114 connected together. The surfaces of the first bracket 113 and the second bracket 114 are perpendicular to each other. The first bracket 113 is detachably connected to the first mounting component 111, forming a receiving space 116. The first connecting end 121 is detachably connected to the second bracket 114. This allows the emergency lighting fixture to be fixedly installed on a wall at a corner of a passageway, making the pre-set emergency markings on the light guide plate 30 clearly visible to people passing through the corner. Furthermore, the second mounting component 112 is a one-piece molded part, integrally cast from aluminum alloy using a casting process. Aluminum alloy is high-strength and lightweight, which is beneficial for the overall lightweight design of the emergency lighting fixture.

[0054] like Figure 8 The second mounting bracket 112 of the emergency lighting fixture shown eliminates the second bracket 114, i.e., as Figure 8 The emergency lighting fixtures shown are similar to those shown. Figures 1 to 7 The emergency lighting fixture shown differs from the mounting assembly 10 in structure, but the rest of the fixture's structure is the same and will not be described further here.

[0055] like Figure 9As shown, the second mounting component 112 includes a first frame plate 113 and a lamp post 115 connected to each other. The surface of the first frame plate 113 is perpendicular to the axis of the lamp post 115. The first frame plate 113 is detachably connected to the first mounting component 111 to form a receiving space 116. The first connecting end 121 is detachably connected to the end of the lamp post 115 away from the first frame plate 113. Figures 1 to 8 Compared to the emergency lighting fixtures shown, such as Figure 9 The second mounting bracket 112 of the emergency lighting fixture shown replaces the second bracket plate 114 with a light pole 115, that is, as Figure 9 The emergency lighting fixtures shown are similar to those shown. Figures 1 to 8 The emergency lighting fixture shown differs from the mounting assembly 10 in structure, but the rest of the fixture's structure is the same and will not be described further here.

[0056] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
