Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to a housing assembly and an indicator light using the same. Background Technology

[0002] As is well known, escape route indicator lights are crucial equipment for ensuring the safe evacuation of people in emergencies. Traditional wall-mounted indicator lights typically have a flat front cover. This structure, when subjected to impact, concentrates the force, making it prone to localized damage and potentially damaging internal electronic components, thus affecting the indicator's effectiveness. Therefore, current wall-mounted indicator lights suffer from insufficient strength. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a housing assembly with higher strength and less susceptibility to damage.

[0004] This utility model also proposes an indicator light having the above-mentioned housing assembly.

[0005] According to a first aspect of the present invention, a housing assembly includes: a back plate, a front plate, and a support rib. The back plate is provided with a mounting area for mounting a light-emitting element. The front plate is mounted on the back plate and can cooperate with the back plate to shield the mounting area. The middle part of the front plate arches outward in a direction away from the back plate, so that the cross-section of the front plate is an arc-shaped curved surface. The support rib is provided on the back plate, and one end of the support rib away from the back plate is provided with an arc-shaped abutment surface that can adapt to the inner surface of the front plate. The arc-shaped abutment surface is in close contact with the inner surface of the front plate.

[0006] The housing assembly according to this utility model embodiment has at least the following beneficial effects: The panel of the sign light adopts an arc-shaped structure, which allows the housing to better disperse the point of force application when subjected to external force, avoiding local stress concentration. Therefore, the housing can withstand most of the impact force, preventing damage to internal components and extending the service life of the lamp. Compared with the traditional planar structure, the sign light using this housing assembly can significantly enhance the overall strength and stability of the product and reduce deformation and damage caused by collision or compression. In addition, a support rib is provided between the back plate and the panel. The support rib not only enhances the impact resistance of the back plate but also provides better protection for the internal light-emitting elements. Furthermore, since the support rib fits and supports the panel tightly along the bending direction of the panel, the panel is less prone to deformation when subjected to impact. The surface of the panel can still maintain its curved shape, thereby ensuring that the panel can always disperse the impact force through its arc-shaped surface, thus ensuring that the sign light can maintain good condition during long-term use. Compared with traditional sign lights, its service life is significantly extended, reducing the replacement frequency and lowering maintenance costs.

[0007] According to some embodiments of the present invention, the panel is curved and arched along its width direction, and the panel remains flat and has a uniform thickness along its length direction.

[0008] According to some embodiments of the present invention, the panel is provided with an indicator mark, which is located in the center of the panel.

[0009] According to some embodiments of the present invention, there are multiple indicator marks, each of which is located in the center of the panel and arranged sequentially along the length of the panel.

[0010] According to some embodiments of the present invention, the supporting rib is located between two adjacent indicator signs, and the supporting rib is configured as a light-blocking element.

[0011] According to some embodiments of the present invention, a light-expanding plate is provided between the back plate and the front plate, and the light-expanding plate shields the mounting area.

[0012] According to some embodiments of the present invention, the arc-shaped contact surface has the same curvature as the cross-section of the panel.

[0013] According to some embodiments of the present invention, a mounting boss is provided inside the back plate, and the end of the support rib cooperates with the mounting boss to surround the mounting area.

[0014] According to some embodiments of the present invention, the back panel is provided with a hook opening, which is recessed from the back of the back panel toward the interior of the back panel.

[0015] An indicator light according to a second aspect of the present invention includes a housing assembly according to the first aspect of the present invention and a light-emitting element, wherein the light-emitting element is mounted in the mounting area.

[0016] The indicator light according to the embodiments of this utility model has at least the following beneficial effects: The panel of the indicator light adopts an arc-shaped structure, which allows the shell to better disperse the point of force application when subjected to external force, avoiding local stress concentration. Therefore, the shell can withstand most of the impact force, preventing damage to internal components and extending the service life of the light fixture. Compared with the traditional flat structure, the indicator light using this shell assembly can significantly enhance the overall strength and stability of the product and reduce deformation and damage caused by collision or squeezing. In addition, a support rib is provided between the back plate and the panel. The support rib not only enhances the impact resistance of the back plate but also provides better protection for the internal light-emitting elements. Furthermore, since the support rib fits and supports the panel tightly along the bending direction of the panel, the panel is not easily deformed when subjected to impact. The surface of the panel can still maintain its curved shape, thereby ensuring that the panel can always disperse the impact force through its arc-shaped surface, thus ensuring that the indicator light can maintain good condition during long-term use. Compared with traditional indicator lights, its service life is significantly extended, reducing the replacement frequency and lowering maintenance costs.

[0029] Reference Figure 1A housing assembly includes a back plate 300, a front panel 100, and a support rib 350. The back plate 300 has a mounting area 370 for mounting a light-emitting element 700. The front panel 100 is mounted on the back plate 300 and can cooperate with the back plate 300 to shield the mounting area 370. The middle part of the front panel 100 arches outward in a direction away from the back plate 300, making the cross-section of the front panel 100 an arc-shaped curved surface. The support rib 350 is disposed on the back plate 300, and one end of the support rib 350 away from the back plate 300 has an arc-shaped abutment surface 355 that can adapt to the inner surface of the front panel 100. The arc-shaped abutment surface 355 is in close contact with the inner surface of the front panel 100. The front panel 100 of the indicator light adopts an arc-shaped structure, which allows the housing to better disperse the point of application of force when subjected to external force, avoiding local stress concentration. Therefore, the housing can withstand most of the impact force, avoid damage to internal components, and extend the service life of the lamp. Compared to traditional flat structures, marker lights using this housing assembly significantly enhance overall strength and stability, reducing deformation and damage caused by impacts or pressure. Furthermore, a supporting rib 350 is provided between the back panel 300 and the panel 100. This rib not only enhances the impact resistance of the back panel but also provides better protection for the internal light-emitting element 700. Moreover, because the supporting rib 350 closely fits and supports the panel 100 along its curvature, the panel 100 is less prone to deformation when impacted. The surface of the panel 100 maintains its curved shape, ensuring that the panel 100 consistently disperses impact force through its arc-shaped exterior, thus ensuring the marker light remains in good condition over long-term use. Compared to traditional marker lights, its lifespan is significantly extended, reducing replacement frequency and maintenance costs.

[0030] It is conceivable that the back panel 300 and the front panel 100 can be connected by snap-fit ​​310 or by screws or other components. The specific implementation method is not unique, but can be adjusted according to the actual situation, and is not limited here.

[0031] In some embodiments, reference is made to Figure 3 Panel 100 is curved and arched along its width, while remaining flat and of uniform thickness along its length. The curvature along its width creates a curved surface on the panel 100, allowing it to absorb impact forces. The flatness and uniform thickness along its length effectively improve the illumination stability of the indicator light and prevent illumination distortion caused by the curvature of the panel 100, ensuring smooth and accurate illumination.

[0032] It is conceivable that the curved surface of panel 100 could also be curved along its length while remaining straight in its width. The specific implementation method is not unique, but can be adjusted according to the actual situation, and is not limited here.

[0033] In some embodiments, reference is made to Figure 1 The panel 100 is equipped with an indicator sign 130, which is located in the center of the panel 100. The indicator sign 130 can be displayed on the panel 100 and is illuminated by the light-emitting element 700, so that people in the scene can easily observe the indicator sign 130. The curved surface of the panel 100 allows the indicator sign 130 to extend in different directions, so that people facing different directions can easily observe the indicator sign 130 on the panel 100, thus enabling it to function.

[0034] In some embodiments, reference is made to Figure 2 The support rib 350 is located between two adjacent indicator signs 130 and is configured as a light-blocking element. The support rib 350 not only supports the panel 100 but also separates the indicator signs 130 on the panel 100. Therefore, the indicator signs 130 on the panel 100 are separated, and a difference in brightness appears between the indicator signs 130 and the support rib 350, thus brightening the indicator signs 130. This allows people in the scene to view the indicator signs 130 more clearly and intuitively, and obtain the corresponding directional guidance.

[0035] Specifically, there are three indicator signs 130, all located in the center of the panel 100 and arranged sequentially along the length of the panel 100. There are two support ribs 350, one between every two adjacent indicator signs 130. These multiple indicator signs 130 can indicate different functions, directions, etc., allowing personnel to simultaneously understand multiple situations within the scene, facilitating appropriate action. The three indicator signs 130 are an escape route marker and two directional arrows. Of course, the number or content of the indicator signs 130 can also vary; the specific implementation is not unique and can be adjusted according to actual circumstances, without limitation.

[0036] In some embodiments, reference is made to Figure 2A light-expanding plate 200 is disposed between the back panel 300 and the front panel 100, and the light-expanding plate 200 shields the mounting area 370. The light-expanding plate 200 can uniformly distribute the light emitted by the light-emitting element 700, thereby ensuring that the back panel 300 is evenly filled with light, and the light is released through the front panel 100. This effectively avoids the problem of insufficient light at the edges due to excessive light concentration, and also avoids overexposure caused by excessive light concentration, thus effectively improving the overall lighting stability of the indicator light.

[0037] In some embodiments, reference is made to Figure 3 The curved abutment surface 355 has the same curvature as the cross-section of the panel 100. The support rib 350 can support the panel 100 from the back plate 300 through the curved abutment surface 355, thus preventing problems such as dents in the middle part of the panel 100 and effectively maintaining the overall curved shape. Therefore, the overall strength of the indicator light can be effectively improved, ensuring that the indicator light can withstand most of the impact force, thereby avoiding damage to internal components and extending the service life of the lamp.

[0038] In some embodiments, reference is made to Figure 5 The back plate 300 is provided with a mounting boss 375, and the end of the support rib 350 cooperates with the mounting boss 375 to surround the mounting area 370. The mounting boss 375 cooperates with the mounting boss 375 to position and install the light-emitting element 700 and the mounting area 370, so that the light-emitting element 700 can be supported and positioned. Therefore, the light-emitting element 700 can be firmly installed in the mounting area 370 and is not easy to fall off.

[0039] Specifically, the panel 100 and the back plate 300 enclose the light-emitting element 700 from the front and rear sides, while the ends of the mounting boss 375 and the support rib 350 surround and abut against the light-emitting element 700 from the side.

[0040] In some embodiments, reference is made to Figure 4 The back panel 300 is provided with a hook opening 330, which is recessed from the back of the back panel 300 towards its interior. The hook opening 330 allows the back panel 300 to be mounted on a wall within the scene, thus enabling the installation of indicator lights. Furthermore, because the hook opening 330 is recessed relative to the back panel 300, after the indicator light is mounted on the wall, the mounting structure can extend into the back panel 300, thereby eliminating the need for the indicator light to protrude outwards relative to the wall due to the mounting structure, and reducing the possibility of the indicator light being damaged by impact.

[0041] The second aspect of this utility model provides an embodiment of an indicator light, including the aforementioned housing assembly and a light-emitting element 700, which is mounted in the mounting area 370. The panel 100 of the indicator light adopts a curved surface structure, which allows the housing to better disperse the point of force application when subjected to external forces, avoiding local stress concentration. Therefore, the housing can withstand most of the impact force, preventing damage to internal components and extending the service life of the lamp. Compared with traditional flat structures, the indicator light using this housing assembly can significantly enhance the overall strength and stability of the product and reduce deformation and damage caused by collisions or compression. The support rib 350 not only enhances the impact resistance of the back plate but also provides better protection for the internal light-emitting element 700. Furthermore, because the support ribs 350 closely fit and support the panel 100 along its curvature, the panel 100 is less prone to deformation when subjected to impact. The surface of the panel 100 maintains its curved shape, ensuring that the panel 100 can consistently disperse impact force through its arc-shaped exterior. This, in turn, ensures that the indicator light maintains good condition over long-term use. Compared to traditional indicator lights, its lifespan is significantly extended, reducing replacement frequency and maintenance costs.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
