[0034] Emergency guide lights, suitable for fire emergency lighting, are one of the most common lighting tools in fire emergencies. They offer long emergency duration, high brightness, and can be used even when mains power is interrupted. In related technologies, the lamp body and cover are mostly connected by screws, and a seal is achieved by the edges of the lamp body and cover meeting. However, gaps between the lamp body and cover cannot prevent small insects or liquids from entering, thus making it impossible to avoid malfunctions due to insects or liquids entering the lamp.

[0035] Based on the above problems, the sealing structure in this disclosure can fill the gap between the lamp body and the cover, thereby preventing insects or liquids from entering the lamp and avoiding lamp malfunctions due to insects or liquids entering the lamp, thus improving the lamp's service life.

[0036] Figure 1 The diagram shown is a schematic representation of the overall structure of an emergency guide light in one embodiment of this disclosure. Figure 2 The diagram shown is a cross-sectional view of an emergency guide light according to one embodiment of this disclosure. Figure 1 and Figure 2 In the example, the emergency guide light 100 includes a light body 110 and a cover 120.

[0037] The lamp body 110 includes a housing 111 and a mounting portion 112. The housing 111 includes a cavity shell 1111 having a receiving cavity and a cover 1112 covering the opening of the receiving cavity, wherein the outward-facing wall of the cover 1112 and the mounting portion 112 together form a mounting surface for mounting a light-emitting element 150. The light-emitting element 150 may be implemented as an LED panel or a plurality of LED beads arranged in an array on the surface of the cover 1112. Those skilled in the art will understand that the receiving cavity is for mounting electrical components, such as batteries, PCB control boards, and wire harnesses. The mounting portion 112 is formed on the edge of the cavity shell 1111 that surrounds the opening, so that the cover 120 mounted on the mounting portion 112 can cover the light-emitting element 150. It is also understood that the detachable connection of the cover 1112 to the cavity shell 1111 facilitates the maintenance and replacement of electrical components within the receiving cavity. Preferably, the cover 1112 is implemented as a PCB control board.

[0038] Exemplarily, the cover 1112 is detachably disposed on the cavity 1111, such as by a threaded connection or snap-fit. Exemplarily, the lamp body 110 is implemented as a rectangle. Correspondingly, the light-emitting element 150 may be implemented in a shape adapted to the shape and area of ​​the lamp body 110, and the cover 120 is also implemented as a rectangle. In other embodiments, the lamp body 110 may also be implemented as a circle or other shapes, and is not limited thereto.

[0039] The cover 120 includes a connecting portion 121 for mounting to the mounting portion 112 and an marking portion 122 for setting an indicator mark. Exemplarily, the cover 120 is made of acrylic sheet. When the lamp body 110 is implemented as a rectangle, the mounting portion 112 is implemented as a square shape; similarly, the connecting portion 121 is implemented as a square shape adapted to the mounting portion 112, so that the connecting portion 121 can be shape-fittedly attached to the mounting portion 112 of the lamp body 110.

[0040] For example, the signage unit 122 is provided with at least one of a running sign, an exit sign, or a directional sign. It should be noted that the choice of signage can be based on the location and function of the emergency guide light 100, and is not limited here.

[0041] It is understood that the emergency guide lights can be applied to 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.

[0042] exist Figure 2 In the example, a light-emitting cavity 130 is formed between the cover 120 and the mounting surface. Those skilled in the art will understand that when mosquitoes or other objects enter the light-emitting cavity 130 of the emergency guide light 100, they will block the light, reduce luminous efficiency, hinder heat dissipation, affect lifespan, increase cleaning and maintenance costs, and a large accumulation may pose a safety hazard.

[0043] Figure 3 The following is a description of this disclosure. Figure 2 A magnified view of A in the diagram. Figure 2 and Figure 3In the example, a mounting structure with a concave-convex fit is formed between the annular periphery of the cover 120 and the lamp body 110, the mounting structure including a groove 113 and a protrusion 123. Exemplarily, the groove 113 is formed in the mounting portion 112 formed on the annular periphery of the lamp body 110, and the protrusion 123 is disposed in the mating portion 121 formed on the annular periphery of the cover 120. More exemplaryly, the protrusion 123 is integrally formed on the cover 120. In other embodiments, the protrusion 123 may also be implemented as a detachable connection to the annular periphery of the cover 120 to facilitate replacement of the worn protrusion 123, for example, via a screw connection.

[0044] Exemplarily, the cover 120 is detachably disposed on the lamp body 110, for example, by snap-fit. Figure 2 In the example, a slot 124 is formed on the cover 120, and a resilient locking block 114 is provided on the lamp body 110. When the protrusion 123 of the cover 120 engages with the groove 113 of the lamp body 110, the locking block 114 is deformed by the pressure of the cover 120. When the locking block 114 is aligned with the slot 124, it returns to its original shape and is engaged in the slot 124, so that the lamp body 110 and the cover 120 remain relatively fixed.

[0045] exist Figure 1 In the example, the slots 124 and the blocks 114 are implemented as multiple sets, and the multiple sets of slots 124 and blocks 114 are distributed at intervals along the annular periphery of the cover 120 between the lamp body 110 and the cover 120.

[0046] Exemplarily, the emergency guide light 100 further includes a sealing structure 140. The sealing mechanism includes a first annular sealing unit and a second annular sealing element 142 disposed between the protrusion 123 and the groove 113 in the mounting structure. Figure 3 The following is an implementation example for illustration. Figure 3In the example, the first annular sealing unit includes two first annular seals 141, one of which is located on the outer sidewall of the protrusion 123, and the other on the inner sidewall of the protrusion 123. The second annular seal 142 is attached to the bottom wall of the groove 113, for example, by bonding or snapping. Exemplarily, both the first annular seal 141 and the second annular seal 142 are made of rubber or silicone. Therefore, when the cover 120 is fixed to the lamp body 110, the protrusion 123 is inserted into the groove 113, and the two first annular seals 141 deform and fill the gap between the protrusion 123 and the opposite sidewall of the groove 113, while the second annular seal 142 deforms and fills the gap between the top surface of the protrusion 123 and the bottom surface of the groove 113. This seals the light-emitting cavity 130 by blocking the external passage through the gap to the light-emitting cavity 130.

[0047] In other embodiments, the two first annular seals 141 may also be provided on opposite side walls of the groove 113, and the second annular seal 142 may be provided on the top surface of the protrusion 123, without limitation.

[0048] Figure 4 The diagram shown is a cross-sectional view of a sealing structure 140 according to an embodiment of this disclosure. Figure 4 In this example, multiple second annular seals 142 may be implemented, with the multiple second annular seals 142 being spaced apart along the depth direction of the groove 113, for example, on the outer side wall of the protrusion 123. This further improves the sealing effect of the sealing structure 140.

[0049] Exemplarily, at least one of the protrusions 123 and the groove 113 has a wall surface that abuts against the second annular seal 142, which is implemented as a curved surface. Figure 4 In the example, the groove wall of the groove 113 that abuts against the second annular seal 142 is curved, and the wall surface of the protrusion 123 that abuts against the second annular seal 142 is also curved. Those skilled in the art will understand that by making the walls of the protrusion 123 and the groove 113 that abut against the second annular seal 142 non-planar, the contact area after the protrusion 123, the groove 113, and the second annular seal 142 abut against each other can be increased, thereby further improving the sealing effect of the sealing structure 140.

[0050] In other embodiments, it may be implemented such that only the wall surface on the protrusion 123 that abuts against the second annular seal 142 is curved; or, only the wall surface on the groove 113 that abuts against the second annular seal 142 is curved, and is not limited thereto.

[0051] For example, the cross-sectional shapes of the curved surfaces on the protrusion 123 and the groove 113 may be the same or different. Figure 4 In the example, the cross-sectional shape of both surfaces is implemented as an arc segment.

[0052] Figure 5 The diagram shown is a cross-sectional view of a sealing structure 140 according to an embodiment of this disclosure. Figure 5 In the example, the cross-sectional shapes of the two curved surfaces are implemented as broken line segments. Preferably, the included angle between two adjacent segments in the broken line segment is implemented to be greater than 90 degrees and less than 180 degrees. Those skilled in the art will understand that if the included angle between two adjacent segments is less than 90 degrees, the compressed second annular seal 142 may not be able to completely fill the gap between the protrusion 123 and the groove 113, thereby reducing the sealing effect.

[0053] In other embodiments, one of the wall surfaces on the protrusion 123 and the groove 113 that abut against the second annular seal 142 is implemented as a curved surface with an arc segment in cross-section, and the other is implemented as a curved surface with a broken line segment in cross-section.

[0054] In summary, this disclosure provides an emergency guide light. The emergency guide light includes a lamp body and a cover. The lamp body is provided with a light-emitting element. The cover is fixedly disposed on the lamp body and forms a light-emitting cavity surrounding the light-emitting element. A convex-concave fitting mounting structure is formed between the annular periphery of the cover and the lamp body. A first annular sealing unit and a second annular sealing member are provided between the protrusion and the groove in the mounting structure; wherein the first annular sealing unit fills the gap between the opposite sidewalls of the protrusion and the groove, and the second annular sealing member fills the gap between the top surface of the protrusion and the bottom surface of the groove. The first annular sealing unit is closer to the opening of the groove than the second annular sealing member; wherein the first annular sealing unit and the second annular sealing member block the external passageway connecting to the light-emitting cavity through the gap. The sealing structure of this disclosure can fill the gap between the lamp body and the cover, thereby preventing insects or liquids from entering the lamp, avoiding malfunctions due to insects or liquids entering the lamp, and improving the lamp's service life.

[0055] The above embodiments are merely illustrative of the principles and effects of this disclosure and are not intended to limit this disclosure. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this disclosure. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this disclosure should still be covered by the protection scope of this disclosure.
