Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, and more particularly to a bendable emergency sign light. Background Art

[0002] Many buildings and public spaces today utilize cylindrical load-bearing columns for aesthetic reasons. These columns often require emergency evacuation sign lights, but traditional sign lights are mostly rigid, unbendable, straight structures. The common approach to this problem in the prior art is to customize a curved fire emergency evacuation sign of the corresponding size based on the column diameter. This requires pre-buried holes in the column, into which the light fixture is then embedded for installation. However, since most cylinders have varying diameters, a separate sign light must be designed and produced for each diameter, which can easily cause delays on-site. Furthermore, most curved sign lights are constructed by bending and welding metal, resulting in high manufacturing costs and the inability to maintain inventory. This creates a wide variety of product models, poor reproducibility, high production costs for single-batch parts, and the inability to interchange parts. This places a significant burden on design, production, and material procurement. Therefore, there is an urgent need to develop a bendable emergency sign light. Utility Model Content

Obviously, the embodiments described are some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work shall fall within the scope of protection of the present invention.

[0025] A bendable emergency sign light in a preferred embodiment of the present invention is as follows: Figure 1-4As shown, the bottom shell 10 includes a bottom shell 10 and a panel 20; a light-emitting component 30 is provided between the bottom shell 10 and the panel 20; the bottom shell 10 includes a first substrate 11 parallel to the panel 20, and first side walls 12 extending from the upper and lower edges of the first substrate 11 toward the panel 20; the first substrate 11 and the two first side walls 12 are mutually enclosed to form a storage groove 13 for accommodating the light-emitting component 30 and the panel 20; a limit component for limiting the upper and lower positions of the light-emitting component 30 and the panel 20 is provided on the bottom shell 10; and two detachable limit components are installed on the left and right sides of the bottom shell 10. The light-emitting component 30 and the plug 40 for limiting the left and right positions of the panel 20; the light-emitting component 30 can be limited and movable left and right in the storage groove 13 between the two plugs 40; the light-emitting component 30 includes a light guide plate 31 parallel to the panel 20, and a flexible light strip 32 that emits light toward the outer surface of the light guide plate 31; the bottom shell 10, the panel 20 and the light guide plate 31 are all made of tough materials. In this embodiment, the bottom shell is extruded from high-toughness plastic, the light guide plate is a translucent high-toughness plastic, and the panel is a bendable metal sheet, which is the basis for the lamp to bend at a large angle.

[0026] The emergency sign light is cleverly designed and comprises a base shell and a panel; both the base shell and the panel are made of tough material and have a base for large-angle bending; a light-emitting component is provided between the base shell and the panel; the base shell comprises a first substrate and two first side walls; the first substrate and the two first side walls are enclosed with each other to form a storage groove; a limit component for the upper and lower limits of the light-emitting component and the panel is provided on the base shell; plugs for limiting the left and right limits of the light-emitting component and the panel are detachably installed on the left and right sides of the base shell; the light-emitting component can move left and right in the storage groove between the two plugs; it can ensure that when the sign light is bent, the light-emitting component can slide slightly left and right in the base shell but will not fall out of the storage groove. The sign light itself has good bendability. The user can apply a bending force to the sign light according to the actual curvature of the cylindrical column. It is compatible with the installation of cylindrical columns of different sizes without customization, and the repeatability and versatility are significantly improved.

[0027] Furthermore, the limiting assembly includes two limiting edges 14, which are respectively provided at the free ends of the two first side walls 12 and limit the panel 20 from leaving the receiving groove 13 in a direction away from the first substrate 11, and two limiting ribs 15, which are respectively provided on the upper and lower sides of the first substrate 11. The limiting edges 14 are long, L-shaped. When the light-emitting assembly and the panel are assembled into the receiving groove, the limiting edges 14 limit the light-emitting assembly and the panel forward along the entire edge, thereby increasing the contact area and ensuring more uniform force on the panel when the marker light is bent. The light-emitting assembly 30 is located between the two limiting ribs 15. The two limiting edges 14 can limit the upper and lower positions of the light guide plate 31. The front surface of the limiting rib 15 supports the panel 20, and the inner surface abuts the light-emitting assembly 30. The two limiting ribs not only provide support for the panel, but also limit the upper and lower positions of the light-emitting assembly, resulting in a stable structure.

[0028] Furthermore, there is a distance difference between the side surface of the limiting edge 14 facing the first substrate 11 and the front side surface of the limiting rib 15; the distance difference is not less than the thickness of the panel 20. When the panel and the bottom shell are installed in place, the front and rear sides of the panel are respectively in contact with the limiting edge and the panel, and the front and rear limits of the panel can be installed more stably on the bottom shell.

[0029] Furthermore, auxiliary ribs 16 are provided on the upper and lower sides of the first substrate 11, one side of the limiting rib 15. The height of the auxiliary ribs 16 is no greater than that of the limiting rib 15. The auxiliary ribs 16 provide partial support for the light guide plate, thereby limiting the forward and backward floating range of the light guide plate.

[0030] Furthermore, a reinforcing boss 17 is provided in the middle of the surface of the first substrate 11 facing the panel 20. This boss 17 extends along the length of the first substrate 11. The upper surface of the boss 17 is flush with the upper surface of the auxiliary rib 16. In this embodiment, the boss 17 serves to position the light guide plate backward and also strengthens the bending resistance of the middle section of the first substrate, reducing deformation of the bottom housing during extrusion cooling. The bottom housing is formed using an extrusion process, which is more cost-effective than injection molds.

[0031] Furthermore, a first groove 18, which is recessed toward the panel 20, is defined on the side of the first substrate 11 facing away from the panel 20. A second groove 19, which is recessed away from the panel 20, is defined on the side of the first substrate 11 facing the panel 20. The first groove 18 and the second groove 19 are located on either side of the reinforcing boss 17. Both the first groove 18 and the second groove 19 facilitate wire embedding, and the rounded edges of both grooves 18 and 19 reduce stress concentration during bending.

[0032] Furthermore, the plug 40 includes a second base plate 41 parallel to the panel 20, and a second side wall 42 fixedly connected to the second base plate 41 and used to position the light guide plate 31. The second side wall 42 is provided with multiple ribs 43 along its length, which not only ensure the strength of the plug 40 but also provide support and reinforcement for the bottom case after assembly. The second side wall 42 distributes the pressure of the panel on the bottom case ribs when the marker light is bent, and also serves as a safety layer in case the retaining edge 14 is damaged.

[0033] Furthermore, the four top corners of the first substrate 11 are respectively provided with fixing holes 111 for screws to pass through; the upper and lower ends of the two second side walls 42 are provided with a plurality of threaded countersunk holes 44 corresponding to the fixing holes 111. The threaded countersunk holes 44 use a countersunk hole design, which can sink the nuts of the screws into the pits, so that the surface of the marker light is flat and has no bumps, reducing the damage caused to pedestrians during collisions; the two plugs 40 play the role of left and right positioning of the light guide plate, and are used with screws to further limit the edge of the face shell to ensure that the face shell will not pop out when it bends on a small diameter cylindrical surface; during installation, the screws pass through the fixing holes and are threadedly fixed to the threaded countersunk holes 44; the plugs and the bottom shell are easy to disassemble and assemble.

[0034] Furthermore, the light-emitting assembly 30 also includes a diffusion film 33 disposed between the light guide plate 31 and the panel 20, and a mainboard 34 disposed on one side of the light guide plate 31 and electrically connected to the flexible light strip 32. In this embodiment, the flexible light strip 32 is disposed above the light guide plate 31. The upper surface of the light guide plate 31 is provided with a plurality of slots 311 corresponding one-to-one to the light beads on the flexible light strip 32. The length of the slots 311 is greater than the length of the light beads. In this embodiment, the slots 311 are arranged in an elongated strip shape to relieve stress when the sign light is bent and to prevent the light beads from straying to the sides during emergency operation. When the light strip is bent, the light beads can move within the corresponding grooves 611 to accommodate the deformation caused by the bending. The plugs on the left and right ends of the bottom shell limit the light-emitting assembly, ensuring that the light-emitting assembly can slide slightly left and right in the storage slot when bent without falling out (to accommodate the situation where the arc length varies with the bending radius). The diffusion film 33 is fixedly connected to the panel to ensure the stability of the patterned light on the panel after bending.
