Description

Technical Field

[0001] This disclosure relates to the field of emergency lighting technology, and more particularly to an emergency light. Background Technology

[0002] Emergency lighting indicator lights are suitable for fire emergency lighting and are one of the most common lighting tools in fire emergencies. They have a long emergency time, high brightness, and can be used in emergency situations when the mains power is disconnected.

[0003] In related technologies, emergency lighting indicator lights are typically mounted on walls or ceilings using a mounting bracket. However, emergency lighting indicator lights that can be mounted on ceilings differ in structure from those that can be mounted on walls. Furthermore, the light guide plates in most existing emergency lighting indicator lights are fixed and cannot rotate around the base, making it impossible to mount ceiling-mountable emergency lighting indicator lights on walls. Additionally, in existing emergency lighting indicator lights, the fixing of the light-emitting element and the assembly of the housing are done separately, resulting in low installation efficiency. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this disclosure is to provide an emergency light that solves the problems in the related art.

[0005] The first aspect of this disclosure provides an emergency light, comprising:

[0006] The housing has at least one first joint portion;

[0007] The lamp body is provided with at least one second joint that is engaged with the at least one first joint. The contact surfaces of the second joint and the first joint are in flat frictional engagement and can rotate relative to each other, so that the lamp body can be positioned at a preset rotation position by the frictional force between the first joint and the second joint.

[0014] In an embodiment of the first aspect, the lamp body further includes an indicator component exposed above the housing; the indicator component includes a light guide plate; the light guide plate is detachably connected to the lamp body corresponding to the support portion.

[0015] In the first aspect of the embodiment, the two opposite side walls of the indicating component are respectively provided with directional marks, and the directional marks on both sides are arranged in the same direction.

[0016] In a first aspect embodiment, the lamp body includes a first splicing shell and a second splicing shell that are spliced ​​together; the supporting part is disposed on the first splicing shell, and the pressing part is disposed on the second splicing shell.

[0017] In an embodiment of the first aspect, the pressing part is implemented as a plurality; the plurality of pressing parts are spaced apart along the extension direction of the lamp body; and / or, the emergency light further includes at least one status indicator light.

[0018] As described above, this disclosure provides an emergency light. The emergency light includes a housing and a lamp body. The housing has at least one first connecting portion. The lamp body has at least one second connecting portion that engages with the at least one first connecting portion. The contact surfaces of the second connecting portion and the first connecting portion are in a flat frictional fit and can rotate relative to each other, so that the lamp body can be positioned at a preset rotational position by the frictional force between the first and second connecting portions.

It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this disclosure can be combined with each other.

[0032] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings, so that those skilled in the art to which this disclosure pertains can readily implement it. This disclosure may be embodied in many different forms and is not limited to the embodiments described herein.

[0033] In this disclosure, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic represented in connection with that embodiment or example is included in at least one embodiment or example of this disclosure. Furthermore, the specific features, structures, materials, or characteristics represented may be combined in any suitable manner in any one or a group of embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples represented in this disclosure, as well as the features of those different embodiments or examples.

[0034] Furthermore, the terms "first" and "second" are used for illustrative purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the representation of this disclosure, "a set" means two or more, unless otherwise explicitly specified.

[0035] For the purpose of clarity, devices unrelated to the description are omitted, and the same or similar components throughout the specification are given the same reference numerals.

[0036] Throughout this specification, when it is said that a device is "connected" to another device, this includes not only "direct connection" but also "indirect connection" by placing other components in between. Furthermore, when it is said that a device "comprises" a certain constituent element, unless otherwise stated otherwise, this does not exclude other constituent elements, but rather implies that other constituent elements may be included.

[0037] While the terms first, second, etc., are used in some examples herein to refer to various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from another. For example, first interface and second interface, etc., are used. Furthermore, as used herein, the singular forms “a,” “an,” and “the” are intended to also include the plural forms unless the context indicates otherwise. It should be further understood that the terms “comprising,” “including,” indicate the presence of the stated feature, step, operation, element, module, item, kind, and / or group, but do not exclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, modules, items, kinds, and / or groups. The terms “or” and “and / or” as used herein are interpreted as inclusive, or mean any one or any combination thereof. Thus, “A, B, or C” or “A, B, and / or C” means “any one of: A; B; C; A and B; A and C; B and C; A, B, and C.” Exceptions to this definition will only occur if the combination of elements, functions, steps, or operations is inherently mutually exclusive in some way.

[0038] The technical terms used herein are for reference only to specific embodiments and are not intended to limit the scope of this disclosure. The singular form used herein includes the plural form unless the statement explicitly indicates otherwise. The word "comprising" as used in this specification means to specify a particular characteristic, region, integer, step, operation, element, and / or component, and does not exclude the presence or addition of other characteristics, regions, integers, steps, operations, elements, and / or components.

[0039] Although not explicitly defined, all terms, including technical and scientific terms used herein, shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. Terms defined in commonly used dictionaries shall be further interpreted as having a meaning consistent with the relevant technical literature and the message of the present disclosure, and shall not be over-interpreted as having an ideal or overly formulaic meaning unless otherwise defined.

[0040] When the lamp body described in this disclosure rotates to a preset position, it can be positioned at that position by the frictional force between the first joint and the second joint, thereby enabling the lamp body in the emergency light to both adjust the indicating angle and be locked at a preset angle. Furthermore, the splicing of the lamp body can both assemble the components and fix the flexible light-emitting element.

[0041] Figure 1 The diagram shown is an overall schematic diagram of an emergency light according to an embodiment of this disclosure. Figure 2 The diagram shown is a cross-sectional view of an emergency light according to one embodiment of this disclosure. Figure 1 and Figure 2In the example, the emergency light includes a housing 100, which includes a cavity 110 and a mounting housing 120. The cavity 110 includes a receiving cavity 1101 for accommodating electrical components, such as batteries, PCB control boards, and wiring harnesses. The receiving cavity 1101 has an opening, for example, formed at the top of the cavity 110. Those skilled in the art will understand that various electrical components can be installed into or removed from the receiving cavity 1101 through the opening.

[0042] For example, the mounting housing 120 can be detachably connected to the cavity housing 110 to close the opening. Figure 3 The image shown is Figure 2 A magnified view of A in the diagram. Figure 3 The illustration shows an embodiment where a first slot 1102 is formed at each end of the cavity shell 110 along its length. An extension portion 121 extends from each end of the mounting shell 120 along its length, penetrating into the receiving cavity 1101. The extension portion 121 is deformable. A triangular first tooth 122 is provided on a wall facing the first slot 1102 at the distal end of the retaining portion. The first tooth 122 includes an inclined surface for abutting against the cavity wall of the receiving cavity 1101 and a flat surface for abutting against the groove wall of the first slot 1102. Therefore, when the mounting shell 120 is closed onto the cavity shell 110, the extension portion 121 deforms due to the pressing action of the first tooth 122 against the cavity wall of the receiving cavity 1101. When the first tooth 122 aligns with the first slot 1102, the extension portion 121 returns to its original shape, causing the first tooth 122 to engage with the first slot 1102 and the flat surface to abut against the groove wall of the first slot 1102.

[0043] Preferably, when the first locking tooth 122 engages with the first locking groove 1102, the mounting shell 120 is flush with the cavity shell 110 to improve the aesthetic appearance of the shell 100.

[0044] For example, both the cavity shell 110 and the mounting shell 120 are made of deformable plastic. Further exemplarily, the extension 121 and the first retaining tooth 122 are integrally formed into the mounting shell 120.

[0045] In other embodiments, the mounting housing 120 can also be connected to the cavity housing 110 by screws, and not in a manner that... Figure 3 Examples are limited.

[0046] Exemplarily, the mounting housing 120 has two spaced-apart mounting holes 1201 corresponding to the area within the opening. Those skilled in the art will understand that, in use, the mounting housing 120 can be fixed to a designated location, such as a ceiling or wall, by first passing screws through the mounting holes 1201 from one side of the extension 121, and then the cavity shell 110 can be attached to the mounting housing 120, thereby achieving the installation of the emergency light. Furthermore, it is understood that the mounting holes 1201 are located within the opening, which avoids any area of ​​the mounting housing 120 exposed to the cavity shell 110, thereby further improving the aesthetic appearance of the housing 100.

[0047] In other embodiments, the mounting hole 1201 may also be formed on the side wall of the cavity 110 adjacent to the opening to further improve the installation applicability of the emergency light.

[0048] Further exemplarily, the shape of the mounting shell 120 is adapted to the shape of the opening; for example, both the mounting shell 120 and the opening are implemented as rectangles. In other embodiments, both the mounting shell 120 and the opening are implemented as circles or ellipses, and not necessarily as circles or ellipses. Figure 2 Examples are limited.

[0049] It is understood that the emergency lights can be used in commercial venues (shopping malls, hotels, and office buildings, etc.) and public facilities (hospitals, schools, libraries, train stations, airports, and subway stations, etc.). Installation locations are typically in corridors, stairwells, and safety exits.

[0050] exist Figure 1 , Figure 2 and Figure 3 In the example, the emergency light further includes a lamp body 200, which is rotatably connected to the housing 100. Exemplarily, a rotating structure is formed between the lamp body 200 and the housing 100, the rotating structure including a pin 211 and a pin hole 212; the pin holes 212 are formed at opposite ends of the housing 100, and pins 211 for insertion into the pin holes 212 are formed at opposite ends of the lamp body 200. Further exemplaryly, the pin 211 has an inclined surface for guiding its engagement with the pin hole 212. Therefore, when it is necessary to combine the housing 100 and the lamp body 200, the inclined surface on the pin 211 first abuts against the area on the lamp body 200 surrounding the pin hole 212, and gradually widens the distance between the two pin holes 212 (the cavity 110 deforms) until the two pins 211 on the lamp body 200 are aligned with the corresponding pin holes 212, and the cavity 110 returns to its original deformation until the pins 211 are inserted into the pin holes 212, thus realizing the hinge connection between the lamp body 200 and the housing 100.

[0051] More preferably, the area of ​​the inclined surface on the pin 211 does not exceed 180 degrees, thereby avoiding the situation where the contact surface between the pin 211 and the pin 211 is reduced due to the area of ​​the inclined surface being too large, which could lead to the pin 211 falling off.

[0052] In other embodiments, the arrangement of the pin 211 and the pin hole 212 can be interchanged, that is, the pin 211 is formed at opposite ends of the housing 100, and the pin hole 212 for the pin 211 to be inserted is formed at opposite ends of the lamp body 200.

[0053] Figure 4 The diagram shown is a cross-sectional view of an emergency light from another perspective in one disclosed embodiment. Figure 2 and Figure 4 In the example, the housing 100 is provided with at least one first joint 130. The lamp body 200 is provided with at least one second joint 210 that engages with the at least one first joint 130. The contact surfaces of the second joint 210 and the first joint 130 are in a flat frictional fit and can rotate relative to each other, so that the lamp body 200 can be positioned at a preset rotational position by the frictional force between the first joint 130 and the second joint 210.

[0054] For example, the contact surface is implemented as an arcuate surface. Figure 4 The illustration shows an embodiment where the first connecting portion 130 and the second connecting portion 210 are both implemented as a single unit. The housing 100 has a first connecting portion 130 extending therefrom and having an arc-shaped cross-section, and the outer edge surface of the lamp body 200 is implemented as the second connecting portion 210. Exemplarily, the first connecting portion 130 is closer to the opening than the pin hole. Therefore, when the lamp body 200 is rotatably connected to the housing 100, the second connecting portion 210, implemented as the outer edge surface of the lamp body 200, abuts against the first connecting portion 130; when the lamp body 200 rotates to a preset position, it can be positioned at that position by the frictional force between the first connecting portion 130 and the second connecting portion 210, thereby enabling the lamp body 200 in the emergency light to both adjust the indicating angle and be locked at a preset angle.

[0055] Preferably, the first joint portion 130 is provided with a contact-enhancing layer 131 to increase the friction between the first joint portion 130 and the outer edge surface of the lamp body 200. For example, the contact-enhancing layer 131 is implemented as a rubber pad or silicone pad laid on the surface of the first joint portion 130; or, the contact-enhancing layer 131 is implemented as elastic protrusions distributed in an array on the first joint portion 130.

[0056] More preferably, the enhanced contact layer 131 is detachably disposed on the first joint 130, for example, by snap-fitting or adhesive, so as to facilitate replacement of the worn enhanced contact layer 131.

[0057] exist Figure 4 In the example, the first joint 130 has a placement area for placing electrical components in the area facing the opening.

[0058] Figure 5 The diagram shown is a structural schematic of the housing in one embodiment of this disclosure. The first joint 130 is implemented as... Figure 4 When the cross-section shown is arc-shaped and closer to the opening than the pin hole 212, the pin hole 212 can be implemented as a semi-circular hole with the arc facing the first joint portion 130. Therefore, when the lamp body is attached to the housing 100, a portion of the outer edge of the lamp body abuts against the first joint portion 130, and a portion of the outer edge of the pin 211 abuts against the pin hole 212. That is, the lamp body 200 is rotatably attached between the first joint portion 130 and the pin hole 212. The advantage of the above arrangement is that it can reduce material costs and reduce the difficulty of attaching the lamp body to the housing 100.

[0059] For example, the contact surface is implemented as a plane. Figure 3 The illustration shows an embodiment where both the first joint 130 and the second joint 210 are implemented in pairs. The two first joints 130 are respectively implemented as opposite end faces of the housing 100 (in...). Figure 3 In the example, the end face where the pin hole 212 is located is shown. The two second joint portions 210 are respectively implemented as the opposite side walls of the lamp body 200. The opposite side walls of the lamp body 200 are rotatably connected to the housing 100 by abutting against the corresponding second joint portion 210. It can be understood that the engagement of the pin 211 and the pin hole 212 guides the relative rotation between the lamp body 200 and the housing 100, while the abutting of the first joint portion 130 and the corresponding second joint portion 210 provides the frictional force to position the lamp body 200 in a preset position.

[0060] Preferably, a friction layer (not shown in the figure) is provided between the first joint 130 and the second joint 210 to increase the friction between the lamp body 200 and the housing 100.

[0061] In other embodiments, Figure 3 Based on the embodiment shown, further configurations can be made. Figure 4 The first joint 130 in the example has an arc-shaped cross-section to further increase the friction between the lamp body 200 and the housing 100.

[0062] Figure 6 The diagram shown is a schematic diagram of the lamp body in one embodiment of this disclosure. Figure 7 The diagram shown is a cross-sectional view of a lamp body according to an embodiment of this disclosure. Figure 6 and Figure 7 In the example, the lamp body 200 includes a flexible light-emitting element 220 and a lamp housing 230. The lamp housing 230 forms a cavity 201, and a support portion 240 is provided in the cavity 201. The support portion 240 has a support surface for supporting the flexible light-emitting element 220. In addition, the cavity 201 also has at least one pressing portion 250 disposed opposite to the support surface to press against the flexible light-emitting element 220.

[0063] The lamp housing 230 includes a first splicing shell 231 and a second splicing shell 232 that are joined together. Exemplarily, both the first splicing shell 231 and the second splicing shell 232 are implemented with a semi-circular cross-section, so that the spliced ​​lamp housing 230 is cylindrical, thereby facilitating rotation when combined with the housing 100. In other embodiments, both the first splicing shell 231 and the second splicing shell 232 are implemented with a rectangular cross-section, so that the spliced ​​lamp housing 230 is prismatic (suitable for...). Figure 3 (The example shown).

[0064] Preferably, a closing portion 2311 is formed at each end of the first splicing shell 231 along its length, used to seal the openings at both ends of the first splicing shell 231 and the second splicing shell 232, so that the spliced ​​lamp housing 230 forms the cavity 201. The pin 211 is formed in the closing portion 2311. Exemplarily, the cavity 201 is used to house the flexible light-emitting element 220, and electrical components adapted to the flexible light-emitting element 220, such as batteries and PCB control boards, are electrically connected to the flexible light-emitting element 220 in the cavity 201 through wire harnesses. For example, the first splicing shell 231 or the second splicing shell 232 has through holes 202 for wire harnesses to pass through. In other embodiments, the cavity 201 can also be implemented as a place to install electrical components, such as batteries, PCB control boards, and wire harnesses.

[0065] Figure 8 The diagram shown is a cross-sectional view of the lamp body from another perspective in one embodiment of this disclosure. Figure 8 In this example, the splicing method of the first splicing shell 231 and the second splicing shell 232 is implemented as a snap-fit. Exemplarily, a snap-fit ​​structure 280 is formed between the two ends of the first splicing shell 231 and the second splicing shell 232 that meet, the snap-fit ​​structure 280 including a second snap groove 2801 that can be brought closer to or moved away from the second snap tooth 281. Figure 3For illustrative purposes, the second splicing shell 232 is deformable. A second slot 2801 is formed in the first splicing shell 231, and a second locking tooth 281 is formed in the second splicing shell 232, the second locking tooth 281 including an inclined pressing surface. Therefore, when the second splicing shell 232 is downward (towards...), Figure 8 (Using the direction in the example as a reference) During the splicing process of the second splicing shell 231, the pressing surface of the second locking tooth 281 first contacts the first splicing shell 231. Since the second splicing shell 232 is deformable, the second locking tooth 281 gradually moves away from the second locking groove 2801 as the second splicing shell 232 moves downward, until the second splicing shell 232 moves downward until the second locking tooth 281 aligns with the second locking groove 2801. Under the action of the deformation restoring force of the second splicing shell 232, the second locking tooth 281 is inserted into the corresponding second locking groove 2801, so as to realize the splicing of the first splicing shell 231 and the second splicing shell 232.

[0066] Preferably, the snap-fit ​​structure 280 is formed only at both ends and the middle region near the length direction of the lamp housing 230. This ensures the connection between the first splicing shell 231 and the second splicing shell 232 while saving manufacturing costs.

[0067] In other embodiments, the first splicing shell 231 or the second locking tooth 281 may also be deformable to achieve the above purpose, and are not limited thereto.

[0068] For example, the second splicing shell 232 is provided with an operation part (not shown in the figure) that causes the second locking tooth 281 to disengage from the second locking slot 2801.

[0069] Figure 9 The diagram shown is a cross-sectional view of the lamp body according to another embodiment of this disclosure. Figure 9 In the example, the first splicing shell 231 and the second splicing shell 232 are connected by screws. For example, the first splicing shell 231 has a first threaded hole, and the second splicing shell 232 has a first countersunk hole. It is understood that the screw passes through the first countersunk hole and is screwed into the first threaded hole, thus locking the first splicing shell 231 and the second splicing shell 232. Preferably, the depth of the first countersunk hole is configured so that the screw is not exposed, to avoid any protrusions on the surface of the lamp housing 230.

[0070] exist Figure 7 and Figure 8In the example, the supporting portion 240 extends along the length of the lamp housing 230, for example, by forming a recessed mounting groove, thus the supporting surface is a concave surface. When the second splicing shell 232 is spliced ​​to the first splicing shell 231, it can surround the supporting portion 240 and form the cavity 201.

[0071] For example, at least one pressing portion 250 is formed in the second splicing shell 232 and extends toward the supporting portion 240. The pressing portion 250 and the supporting portion 240 cooperate to form a light source positioning area, and the flexible light-emitting element 220 is disposed in the light source positioning area and is clamped when the pressing portion 250 and the supporting portion 240 cooperate. The flexible light-emitting element 220 is implemented as a flexible LED light strip or light belt. For example, before the first splicing shell 231 and the second splicing shell 232 are spliced ​​together, the flexible light-emitting element 220 is placed on the supporting part 240. When the second splicing shell 232 is spliced ​​to the first splicing shell 231, the pressing part 250 of the second splicing shell 232 presses the flexible light-emitting element 220 against the supporting part 240. This achieves the assembly of the lamp body 200 while also fixing the flexible light-emitting element 220 to the lamp shell 230, preventing the flexible light-emitting element 220 from being damaged due to loosening or shaking during use.

[0072] exist Figure 7 In the example, multiple pressing portions 250 are implemented, and these multiple pressing portions 250 are spaced apart along the length of the lamp housing 230. Preferably, the area of ​​each pressing portion 250 that abuts against the flexible light-emitting element 220 is implemented as a plane. This improves the pressing effect on the flexible light-emitting element 220 while preventing damage to the flexible light-emitting element 220 during the pressing process. More preferably, the wall surface of each pressing portion 250 that abuts against the flexible light-emitting element 220 is provided with an insulating elastic layer (not shown in the figure), such as a rubber layer or a silicone layer. The elastic layer is compressed and deformed during the pressing process, thereby further improving the pressing effect on the flexible light-emitting element 220 and preventing damage to the flexible light-emitting element 220 due to rigid connection, such as vibration.

[0073] For example, the pressing part 250 is integrally formed with the second splicing shell 232, such as by injection molding. In other embodiments, the pressing part 250 may also be implemented as a detachable connection to the second splicing shell 232, such as by snap-fit ​​or screw connection.

[0074] For example, the pressing portion 250 may be implemented as a plate, such as a pressure plate. In other embodiments, the pressing portion 250 may also be implemented as a column, such as a pressure column, and is not limited thereto.

[0075] In other embodiments, the pressing portion 250 may also be implemented as a single unit. One pressing portion 250 extends along the length of the flexible light-emitting element 220 to press the flexible light-emitting element 220 against the supporting portion 240 when the second splicing shell 232 is spliced ​​to the first splicing shell 231. It is understood that when the pressing portion 250 is implemented as a single unit, the area of ​​the pressing portion 250 that abuts against the flexible light-emitting element 220 can also be implemented as a plane, and the wall surface that abuts against the flexible light-emitting element 220 is provided with an insulating elastic layer; therefore, this will not be elaborated upon here.

[0076] exist Figure 7 and Figure 8 In the example, the first splicing shell 231 further includes two clamping portions 2312 disposed at opposite ends of the support portion 240 along its length direction, to clamp the flexible light-emitting element 220 onto the support portion 240. For example, the clamping portions 2312 are located on the first splicing shell 231 at a height higher than (…). Figure 8 (The direction in the example is a reference) The position of the support portion 240 extends along the length direction of the support portion 240. Those skilled in the art will understand that when the flexible light-emitting element 220 is placed on the support portion 240, the flexible light-emitting element 220 is bent until both ends are first inserted between the corresponding clamping portions 2312 and the support portion 240, and then the flexible light-emitting element 220 is flattened to fit the support surface. Preferably, the extension length of the clamping portion 2312 can be adjusted according to the length of the flexible light-emitting element 220 to avoid affecting the installation of the flexible light-emitting element 220.

[0077] For example, a light-emitting port 2313 is formed on the first splicing shell 231 in the area corresponding to the support portion 240, which connects the cavity 201 to the outside. Further exemplarily, the width of the light-emitting port 2313 is smaller than the width of the support portion 240, thereby restricting the flexible light-emitting element 220 from moving out of the cavity 201 from the light-emitting port 2313.

[0078] Figure 10 The diagram shown is a schematic diagram of the lamp body in one embodiment of this disclosure. Figure 11 The diagram shown is a cross-sectional view of a lamp body according to an embodiment of this disclosure. Figure 10 and Figure 11 In the example, the lamp body 200 also includes an indicator component 290 that exposes the housing 100, the indicator component 290 including a light guide plate 291.

[0079] For example, the light guide plate 291 is disposed on the first splicing body corresponding to the flexible light-emitting element 220. For instance, the light guide plate 291 is detachably disposed on the first splicing body and one end is inserted into the light-emitting port 2313. The detachment and connection are implemented by snap-fit ​​or screw connection.

[0080] by Figure 11 The illustrated embodiment further includes a U-shaped frame 292. The light guide plate 291 is slidably coupled to the U-shaped frame 292. For example, the edge of the U-shaped frame 292 has a groove (not shown) adapted to the thickness of the light guide plate 291. The light guide plate 291 is slidably coupled to the U-shaped frame 292, and gaps are formed between the two ends of the light guide plate 291 and the U-shaped frame 292 for the edge of the first splicing body to be inserted.

[0081] For example, a second threaded hole is formed at each end of the length direction of the first splicing body, and a second countersunk hole is formed on the U-shaped frame 292 at the position corresponding to the second threaded hole. Therefore, when it is necessary to install the light guide plate 291 on the lamp housing 230, the light guide plate 291 is first slidably coupled into the U-shaped frame 292, then the end of the light guide plate 291 exposed in the U-shaped frame 292 is inserted into the light emission port 2313, and the edge of the first splicing body is inserted into the corresponding gap. Finally, the U-shaped frame 292 is fixed to the first splicing body with screws to achieve relative fixation between the light guide plate 291 and the lamp housing 230.

[0082] Exemplarily, the light guide plate 291 includes a marking section for setting indicator signs 2911. Exemplarily, the light guide plate 291 is made of acrylic sheet. Exemplarily, the marking section is provided with at least one of running signs, installation exit signs, or directional indicator signs 2911. It should be noted that the selection of signs can be chosen according to the location and function of the lamp body 200, and is not limited here.

[0083] As a further example, the two opposite side walls of the light guide plate 291 are respectively provided with indicator marks 2911, and the indicator marks 2911 on the two side walls are arranged in the same direction so that people on both sides can see the indicator marks 2911.

[0084] In summary, this disclosure provides an emergency light. The emergency light includes a housing and a lamp body. The housing has at least one first connecting portion. The lamp body has at least one second connecting portion that engages with the at least one first connecting portion.
