Description

Technical Field

[0001] This utility model relates to the field of emergency sign light technology, and in particular to a novel emergency sign light. Background Technology

[0002] Emergency sign lights are fire-fighting equipment that provide evacuation guidance and emergency lighting in emergencies such as fires and power outages. Their core function is to provide clear escape route indications to people through high-brightness light sources and standardized graphic symbols such as arrows and text, ensuring that safety exits can be quickly located in complex environments. Emergency sign lights must meet requirements such as explosion-proof performance, high protection level, and continuous lighting time, and must be adapted to special working conditions in flammable and explosive environments to ensure sufficient visibility even in smoky environments.

[0003] In related technologies, the fixing methods of the light-transmitting panel and the housing, such as clips or adhesives, are prone to displacement or detachment under long-term vibration or temperature fluctuations, resulting in blurred markings or uneven light distribution, reducing the accuracy of emergency guidance. Replacing the light-transmitting component requires disassembling the entire housing, which is cumbersome and can easily damage internal electrical components. This increases maintenance difficulty and time costs, especially in high-altitude or complex environments. Moreover, the sealing structure between the light-transmitting component and the housing relies on a single sealant, which is prone to failure due to aging or mechanical stress, leading to a decrease in explosion-proof performance or moisture damage to the internal circuitry.

[0004] Therefore, an optimized explosion-proof housing structure and light-transmitting component fixing scheme are needed to solve the above problems. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] This utility model provides a method such as Figures 1 to 9 The new type of emergency sign light shown includes: The explosion-proof enclosure 1 has an opening 11 on one side, and an explosion-proof cavity 12 is formed inside the opening 11. A power supply 12a and a control component 12b are installed inside the explosion-proof cavity 12. An illumination slot 13 is formed on one side of the explosion-proof enclosure 1. The light strip 2 can be installed in the lighting groove 13 by means of, for example, a snap-on structure. The snap-on is preferably made of flame-retardant polyurethane material, which has good temperature resistance. The light-transmitting component 3 is fixedly installed in the lighting groove 13 at one end, opposite to the light strip 2, and an emergency sign 31 is set on the light-transmitting component 3; The explosion-proof enclosure cover 4 is installed on the side of the explosion-proof enclosure 1 with the opening 11 and covers the opening 11.

[0023] It should be noted that, as Figure 5As shown, the explosion-proof housing 1 also houses components such as a power storage module, a testing module, and a status indicator module. Each component performs its corresponding function. The explosion-proof housing 1, as the core protective structure, is made of cast metal alloy. An explosion-proof cavity 12 on one side provides physical isolation space for the power supply 12a, control components 12b, and other components, effectively blocking the influence of external hazardous environments on the internal circuitry. Simultaneously, the separation between the explosion-proof cavity 12 and the lighting slot 13 further reduces the risk of failure caused by high temperatures or mechanical stress. In the layout of the lamp strip 2 and the light-transmitting component 3, the light-transmitting component 3 is fixedly installed within the lighting slot 13 and opposite to the lamp strip 2. The precise alignment of the light source and the sign is ensured, and the light-transmitting component 3 can further expand the illumination range of the light strip 2, so that the emergency sign 31 can still remain clearly visible in low-light environments; the explosion-proof cover 4 covers the opening 11 of the explosion-proof housing 1, and forms a closed space by using a plane that meets the national standard explosion-proof requirements and the explosion-proof housing 1, thereby improving the explosion-proof level of the overall structure; in addition, the fixing method of the explosion-proof housing 1 and the light-transmitting component 3 achieves the stability of the mechanical connection through the interlocking structure of the lighting groove 13, avoiding the loosening problem caused by vibration or temperature difference due to the snap or glue method, thus ensuring the long-term reliable operation of the emergency sign light under complex working conditions.

[0024] In some embodiments of this utility model, such as Figures 2 to 9 As shown, the light-transmitting component 3 includes a lens 32 and a light-transmitting plate 33. The lens 32 is installed in the lighting slot 13, opposite to the light strip 2. The light-transmitting plate 33 is fixedly connected to the lens 32. The emergency sign 31 is set on the light-transmitting plate 33.

[0025] When the light strip 2 is directly installed in the lighting groove 13, the limited emission angle of the light source can easily lead to insufficient brightness in the edge area of ​​the light-transmitting component 3, forming light spots or dark areas, which affects the uniform visibility of the sign. Therefore, a lens 32, which is embedded in the lighting groove 13 and set opposite to the light strip 2, is used to diffuse or refract the light emitted by the light strip 2, so that the light originally concentrated in the axial direction of the light strip 2 is dispersed to a wider angle, thereby ensuring that the entire surface of the light-transmitting plate 33 is uniformly illuminated, thus improving the overall brightness of the light-transmitting plate 33. Furthermore, the light-transmitting plate 33 adopts a double-sided light-transmitting structure, so that after the light passes through the light-transmitting plate 33 from the side of the light strip 2, the luminous and clear emergency sign 31 (such as the words "Safety Exit" or arrows) can be seen from both sides of the light-transmitting plate 33. This maximizes the utilization rate of the light source, ensures the double-sided visibility of the sign, and ensures the long-term stability of the equipment, meeting the requirements of the new national standard for multi-angle visibility and brightness uniformity of emergency lighting fixtures.

[0026] Based on the above embodiments, such as Figure 9As shown, a slot 32a is formed on the side of the lens 32 away from the light strip 2, and the light-transmitting plate 33 is embedded in the slot 32a; wherein, resin is filled between the light-transmitting component 3 and the lighting groove 13.

[0027] The slot 32a securely fixes the light-transmitting plate 33 and the lens 32 through mechanical fitting, preventing axial displacement or rotational shift of the light-transmitting plate 33 after installation. This ensures long-term precise alignment between the light source and the marking layer, which is particularly suitable for double-sided light-transmitting plate 33 structures. It ensures uniform light distribution on both sides of the marking layer, preventing deformation of the light-transmitting plate 33 or misalignment of the marking layer due to uneven force on one side. Simultaneously, filling the space between the light-transmitting component 3 and the lighting groove 13 with resin (such as epoxy resin) further strengthens the overall structure. The resin filler, through both physical bonding and mechanical embedding, compensates for the insufficient lateral vibration resistance of the slot 32a fitting structure, effectively... It prevents external moisture, dust and other pollutants from entering the interior of the lighting slot 13, improving the IP protection level of the equipment. Moreover, the transparency of the resin will not interfere with the light transmission. At the same time, its micro-deformation buffering ability after filling can absorb stress concentration during the installation process, preventing the lens 32 and the light-transmitting plate 33 from cracking or falling off due to thermal expansion and contraction. It not only solves the stability problem caused by the single fixing method of the light-transmitting component 3, but also improves the durability of the equipment in complex environments through the sealing effect of the resin. Ultimately, it enables the emergency sign 31 to achieve uniform brightness and long-term stable display under the premise of double-sided visibility, meeting the strict requirements of the new national standard for the vibration resistance, dust and water resistance and continuous lighting performance of lamps.

[0028] Based on the above embodiments, refer to Figure 1 A decorative border 34 is provided around the light-transmitting panel 33, with both ends of the decorative border 34 fixedly connected to the explosion-proof housing 1. This serves to protect the light-transmitting panel 33, cover its sharp corners to prevent injury to pedestrians, and provide different decorative effects for different scenarios. Furthermore, eye-catching warning elements such as raised stripes can be provided on the surface of the explosion-proof housing cover 4. Figure 1 and Figure 3 As shown, it can further serve an emergency function, and special prompting elements can be added as needed to expand its application. Border decorations and prompting elements can also be adapted for installation in areas such as... Figure 2 and Figure 3 The new emergency sign lights of different specifications and lengths are shown (not shown in the figure).

[0029] It should be noted that the reference is as follows: Figure 2 and Figure 3 As shown, the explosion-proof housing 1 can be extended or shortened to both sides according to different length requirements, and the length of the partition cavity 14 can be adjusted accordingly. The corresponding assembly and fixing positions can be adjusted according to the change in length, so as to better adapt to actual needs and form a new type of emergency sign light with various specifications and lengths.

[0030] In some embodiments of this utility model, such as Figure 7 As shown, the explosion-proof housing 1 also includes a partition cavity 14, which is disposed at both ends of the explosion-proof housing 1; the explosion-proof housing 1 is provided with a partition plate 15 corresponding to the partition cavity 14, and the partition plate 15 covers the partition cavity 14.

[0031] The partition cavity 14 is located at both ends of the explosion-proof housing 1, which is equivalent to adding two buffer zones between the explosion-proof cavity 12 (which houses the power supply 12a and the control component 12b) and the external environment. When the explosion-proof cavity 12 is subjected to local high temperature or sparks due to abnormal conditions (such as short circuit or overload), the cavity structure of the partition cavity 14 can delay the explosion propagation path, reduce the intensity of the shock wave through the dissipation effect of gas expansion, and also form a thermal blocking layer. When the heat in the explosion-proof cavity 12 is conducted to the outside through the housing, the air layer of the partition cavity 14 (or the thermal insulation material that may be filled in the future) can significantly reduce the heat conduction efficiency.

[0032] Based on the above embodiments, under the premise of meeting explosion-proof safety, the partition cavity 14 can also be used as a multi-functional modular expansion interface to install modules such as temperature sensors or gas concentration detectors that monitor the temperature of the main cavity or the concentration of combustible gas in the surrounding environment in real time, and auxiliary heat dissipation structures that can disperse the heat generated by the explosion-proof cavity 12 to the outer wall of the explosion-proof housing 1 to expand the performance and function of the lamp.

[0033] In some embodiments of this utility model, such as Figure 4 As shown, a mounting post 12c is provided inside the explosion-proof cavity 12. The power supply 12a and the control component 12b are mounted inside the explosion-proof cavity 12 via the mounting post 12c. The mounting post 12c separates the power supply 12a and the control component 12b from the inner wall of the explosion-proof cavity 12, avoiding stress concentration problems that may be caused by shell deformation or vibration due to direct fixing. When the explosion-proof cavity 12 is subjected to external impact, the mounting post 12c can absorb part of the vibration energy through its own elastic deformation or buffer structure, such as rubber pads or damping bolts, thereby reducing the risk of displacement of internal components. Moreover, the mounting post 12c can be flexibly arranged at any position inside the explosion-proof cavity 12, allowing the power supply 12a and the control component 12b to be arranged in layers or zones according to functional requirements, thereby reducing heat conduction interference and improving the thermal management efficiency of the equipment.

[0034] In some embodiments of this utility model, such as Figure 4 As shown, an installation hole 16 is provided on one side of the explosion-proof housing 1, which provides a connection channel for the power supply line 12a, signal line and other cables required inside the lamp to be connected to the external system.

[0035] In some embodiments of this utility model, such as Figure 7As shown, the explosion-proof housing 1 includes an expansion block 17 protruding towards the explosion-proof cavity 12, and multiple expansion blocks 17 are evenly spaced along the circumference of the opening 11; the explosion-proof housing 1 has a connection hole 18, which is correspondingly arranged with the expansion block 17.

[0036] The expansion block 17 protrudes into the explosion-proof cavity 12, significantly increasing the wall thickness of the explosion-proof housing 1 in this area and locally enhancing the explosion-proof performance of the explosion-proof housing 1. Moreover, the expansion block 17 is evenly distributed around the opening 11, which not only optimizes the uniformity of the force on the explosion-proof housing 1, but also provides a more stable support surface for subsequent connections through its protruding structure. The distribution density of the connecting holes 18 matches the spacing of the expansion block 17, further enhancing the rigid connection between the explosion-proof housing cover 4 and the explosion-proof housing 1 and the partition plate 15, avoiding the risk of loosening due to vibration or external force.

[0037] Based on the above embodiments, such as Figure 4 As shown, a sealing groove 11a is formed around the explosion-proof cavity 12 in the circumferential direction of the opening 11. An elastic sealing element such as silicone rubber or EPDM rubber gasket is provided in the sealing groove 11a. When the explosion-proof shell cover 4 is installed on the explosion-proof shell 1 through the connection hole 18, it cooperates with the sealing groove 11a. The elastic sealing element in the sealing groove 11a can automatically fill the gap and maintain the sealing performance. The sealing groove 11a provides an additional all-round blocking path for explosion energy around the opening 11. According to the requirements of different implementation scenarios, the depth of the sealing groove 11a and the groove spacing can be adjusted to effectively suppress the flame propagation speed.

[0038] In some embodiments of this utility model, such as Figure 4 As shown, wall mounts 19 are provided on both sides of the explosion-proof housing 1. Users can choose different installation accessories according to their actual needs, such as wall mount brackets, expansion bolts or magnetic fasteners, so as to adapt to various installation bases such as walls, pipes, and columns. When the light fixture needs to be adjusted or replaced, it can be re-fixed by the wall mount 19 brackets without disassembling the explosion-proof housing 1 or damaging the original sealing structure, thereby reducing maintenance costs.

[0039] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
