[0002] In the field of modern public safety facilities, emergency lighting is a crucial piece of equipment for ensuring personnel evacuation and rescue operations in emergencies, and its lighting effect is of paramount importance. Most emergency lights currently on the market use traditional single-lens or reflector designs to project and distribute light. These traditional designs have significant drawbacks: firstly, emergency lights using ordinary lenses cannot effectively focus light vertically downwards, resulting in insufficient ground illumination and difficulty in clearly displaying evacuation routes, obstacles, and other critical information, increasing the risk of personnel evacuating in darkness; secondly, the lack of proper control over light diffusion leads to uneven peripheral light distribution, with some areas being overly bright and causing glare, while other areas are dimly lit, failing to meet the overall visibility requirements for emergency lighting. Especially in densely populated and complex spaces such as large shopping malls and office buildings, these unreasonable light distribution problems severely affect the effectiveness of emergency lighting, thereby reducing evacuation efficiency and threatening life and property safety. Therefore, there is an urgent need for an emergency lighting design that can effectively improve light distribution, enhance vertical focusing brightness, and ensure uniform peripheral diffusion brightness.

[0025] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] This utility model discloses a combination of appendix Figure 1The emergency lighting lamp shown consists of two main core components: a base shell 1 and a lens cover 2. The base shell 1 has a carefully designed groove 7 in the middle, and the lens cover 2 fits snugly over this groove 7. Furthermore, the lens cover 2 employs advanced Fresnel lens technology (i.e., a Fresnel lens, an optical lens invented by the French physicist Augustin Fresnel, which significantly reduces material usage and weight by dividing the continuous curved surface of a traditional lens into a series of concentric annular grooves, while retaining the basic optical functions of a lens).

[0027] like Figure 1 , 2 As shown in Figure 3, a battery compartment 28 and a removable cover 27 are provided on the bottom surface of the bottom shell 1. The battery 26 is placed in the battery compartment 28 and fixed by the cover 27. The battery 26 passes through the bottom shell 1 and is electrically connected to the circuit board 3. The circuit board 3 is cleverly arranged inside the bottom shell 1, and an LED is precisely positioned at the center of the circuit board 3. Several locking blocks 8 are evenly distributed on the bottom surface of the groove 7 in the middle of the bottom shell 1. Each locking block 8 is equipped with a movable buckle. A well-fitting slot 18 is reserved between the movable buckle and the bottom surface of the groove 7, and the circuit board 3 is securely engaged through this slot 18. Specifically, the movable latch consists of two parts: a connecting seat 15 and a latching plate 16. The connecting seat 15 is securely installed on the inner wall of the groove 7. One end of the latching plate 16 is tightly connected to the connecting seat 15, and the other end forms a slot 18. Notably, the latching plate 16 has a unique shape that slopes towards the center of the groove 7 from the end connected to the connecting seat 15 to the other end. This inclined structure design has significant advantages, guiding the circuit board 3 to slide more smoothly into the slot 18 during installation. After installation, the strong clamping force generated by the elastic deformation of the latching plate 16 further secures the circuit board 3, effectively preventing it from coming out and ensuring that the circuit board 3 always maintains a stable installation state. This innovative latching design greatly improves the convenience of installing and removing the circuit board 3. At the same time, the movable latch, with its unique elastic structure, can effectively resist the bumps during transportation and the vibrations during daily use, preventing the circuit board 3 from shaking or shifting, and effectively enhancing the reliability and stability of the circuit board 3 installation.

[0028] Combined with appendix Figure 4As shown, we have adopted an innovative structural design, using a crimped injection-molded wire clip as the power cord connector. This connector fits snugly into the snap-fit ​​groove 11 on the housing, not only meeting the needs of rapid installation but also easily passing rigorous tensile tests to ensure the stability of the power cord connector in various complex environments. The snap-fit ​​groove 11 is equipped with a specially designed limiting buckle 13, which can firmly lock the connector in place, effectively avoiding the risk of the power cord connector loosening or falling off. In addition, this structure can be flexibly adapted to meet the requirements of different IP protection levels through a glue application process, ensuring that the emergency lighting lamp receives a stable power supply under any circumstances, and strongly guaranteeing the continuous and stable operation of the lighting function.

[0029] In addition, a precisely positioned shoulder 14 is provided on the inner side of the opening edge of the groove 7, and the lens cover 2 is precisely fastened onto the shoulder 14. The shoulder 14 not only serves as a groove for applying adhesive to the lens mounting surface, adapting to the adhesive application process and flexibly meeting the requirements of different protection levels (IP), but also provides a clear and precise positioning reference for the installation of the lens cover 2, significantly enhancing the sealing performance of the connection between the lens cover 2 and the base shell 1. This feature effectively prevents external impurities such as dust and moisture from entering the lamp body, providing comprehensive protection for internal electronic components from potential damage and extending the lifespan of the lamp.

[0030] like Figure 3 As shown, a wire guide groove 17 is specially provided on the bottom shell 1, and an indicator light and a light guide 19 are configured on the circuit board 3. The light guide 19 is made of materials such as fiber optic cable, laser light guide, or light guide column, which can effectively transmit the light from the indicator light on the circuit board 3 to the surface of the lamp, realizing the communication display function of the indicator light. One end of the light guide 19 is tightly connected to the indicator light, and the other end passes through the wire guide groove 17 and extends to the outside of the lens cover 2, thereby achieving the purpose of communication display of the indicator light on the surface of the lens cover. The setting of the wire guide groove 17 provides reliable physical protection for the light guide 19, avoiding it from being squeezed or worn in the complex environment inside the lamp; on the other hand, it can guide the light 19 to be transmitted smoothly along a predetermined path, so that the working status of the indicator light can be clearly and intuitively displayed to the user through the light guide ring, making it convenient for the user to understand the operating status of the lamp at any time. The preferred solution is to set the wire guide groove 17 in one of the connecting seats 15. This layout can make full use of the limited space inside the lamp, making the overall structure more compact and reasonable, and further reducing the potential risk of damage to the light guide 19.

[0031] like Figure 2 , 5As shown in Figure 6, the bottom surface of the base shell 1 is also provided with a backing strip 20 for installation. The backing strip 20 can be pre-fixed to various installation surfaces. The backing strip 20 is made of a variety of materials, including metal stamping, plastic injection molding, and aluminum alloy die casting. Among them, the metal stamping backing strip 20 is sturdy and durable, suitable for industrial sites with high strength requirements; the plastic injection molding backing strip 20 is lightweight and low-cost, and is often used in ordinary civil buildings; the aluminum alloy die casting backing strip 20 has both good heat dissipation performance and corrosion resistance, and performs well in some areas with special environmental adaptability requirements. For ease of construction, the backing strip 20 is installed first, and then the lamp is pushed in for installation. The bottom surface of the base shell 1 is also provided with a limiting groove 21, in which the backing strip 20 can be flexibly slidably installed. One end of the limiting groove 21 is set as an open end 22, and the other end is provided with a stop block 23. A limiting plate 24 is also provided on the side of the limiting groove 21 opposite to the bottom surface of the base shell 1. The installer can first fix the back strip 20 to the wall, ceiling or other installation surface using expansion screws, glue or other means. Then, align the base shell 1 of the light fixture with the back strip 20 and easily slide it into the limiting groove 21 from the opening 22. A snap-fit ​​connector 25 is provided on the inner side of the limiting plate 24 near the opening 22 to securely snap the back strip 20 into the limiting groove 21.

[0032] This innovative structural design provides emergency lighting with exceptional installation flexibility. Users can freely adjust the position of the backing strip 20 within the range defined by the limiting groove 21, precisely altering the installation height and angle of the light fixture to perfectly adapt to different installation environments, according to the specific needs of the actual installation scenario. Simultaneously, the snap-fit ​​connector 25 ensures that the backing strip 20 remains firmly in place after installation, preventing slippage and guaranteeing the reliability of the light fixture installation. Furthermore, this method of installing the backing strip 20 first and then pushing in the light fixture significantly improves construction efficiency, reduces the time spent by construction personnel working at heights, lowers construction difficulty and safety risks, and provides strong support for the rapid and convenient installation of emergency lighting.

[0033] like Figure 7As shown, the lens cover 2 tightly covers the base shell 1 and employs advanced Fresnel lens technology. A convex lens 4 is located in the center of the lens cover 2, or several concentric rings of convex lenses 5 arranged outwards from the center (as shown by the dotted line in the diagram). Simultaneously, the lens cover 2 also includes several concave lens rings 6 arranged around the central convex lens 4 or convex lens rings 5, arranged in layers on the outer sides (as shown by the dotted line in the diagram). The light-facing surface of the central convex lens 4 or convex lens rings 5 ​​is convex, which efficiently converges light in a vertically downward direction, significantly improving the illumination brightness in that direction. This allows important areas such as evacuation routes and key signs to be clearly illuminated, providing reliable visual guidance for personnel evacuation in emergency situations. The outer concave lens ring 6 (with a concave surface facing the light) can evenly diffuse the light, effectively avoiding localized overly bright or dark areas in the lighting area. This makes the light distribution in the emergency lighting coverage area more uniform and harmonious, greatly reducing glare interference with people's vision, comprehensively improving the overall lighting effect, and providing a higher quality and more comfortable lighting environment for emergency scenarios.

[0034] In summary, this emergency lighting design, through its unique Fresnel lens structure, achieves a perfect combination of high-brightness vertical focusing and uniform diffusion of peripheral light, greatly enhancing the emergency lighting effect and providing a clear and reliable lighting environment for personnel evacuation and rescue. In terms of structural design, the stable installation of the circuit board 3 and power cord connector, and the tight fit between the lens cover 2 and the base shell 1, effectively ensure the stability and safety of the internal components of the lamp. The ingenious layout of the cable tray 17 and the light guide 19 allows for a direct display of the indicator light status. Furthermore, the innovative installation structure of the back strip 20 and the limiting slide groove 21 on the base shell 1 not only improves the flexibility and applicability of installation but also significantly enhances construction efficiency and reduces construction risks. The overall design balances functionality, stability, and practicality, providing a more efficient, reliable, and convenient solution for the emergency lighting field.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
