Description

Technical Field

[0001] The utility model belongs to the technical field of explosion-proof electrical equipment, in particular to an explosion-proof fire emergency sign light. Background Art

[0002] Traditional fire emergency sign lights typically rely on a single battery pack as a backup power source. In the event of a fire or other emergency, if the battery pack is damaged by external factors (such as heat or impact), the emergency lighting will fail, seriously impacting evacuation and rescue efforts. Furthermore, many emergency lighting fixtures lack explosion-proof performance, making them unsuitable for the specialized needs of flammable and explosive environments like those in the petroleum and chemical industries. Utility Model Content

[0003] The purpose of the utility model is to provide an explosion-proof fire emergency sign light, aiming to improve the reliability and safety of the emergency lighting system in emergency situations, especially in high-risk environments where explosions may occur.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an explosion-proof fire emergency sign light, comprising a wiring cavity, a power cavity, an emergency lighting fixture, and a mounting bracket. The wiring cavity is connected to the power cavity, which is connected to the emergency lighting fixture. There is a mounting bracket on each side of the emergency lighting fixture. A compression nut is provided on each side of the wiring cavity. A wiring cavity cover is provided on the upper surface of the wiring cavity. A wiring housing and wiring terminals are provided inside the wiring cavity. A controller, a first battery pack, a protective plate, and a second battery pack are provided inside the power cavity. A light source board, a light guide plate, an indicator sign, and a face cover are provided inside the emergency lighting fixture. The wiring cavity is tightly connected to the power cavity, which is connected to the emergency lighting fixture to form a compact and stable structure. A mounting bracket is provided on each side of the emergency lighting fixture to facilitate flexible installation. The power cavity innovatively houses the first and second battery packs, which are independent and serve as backup for each other. This design significantly reduces the risk of the entire emergency lighting system being paralyzed due to failure of a single battery pack, thereby improving the system's reliability and durability. A protective plate is placed between the first and second battery packs. If one battery pack is impacted, the other is protected by the plate, enhancing the reliability and durability of the present invention and reducing the risk of backup power failure.

[0005] Preferably, the compression nut is a three-section design, including a sealing gasket, an external thread, and a hexagonal nut, which can effectively seal and prevent external gas from penetrating, thereby enhancing the protection of the two battery packs and preventing the explosion shock wave from directly acting on the two battery packs and causing a secondary accident.

[0006] Preferably, the light source board is provided with a plurality of LED lamp beads, which have high luminous efficiency characteristics and can provide high-brightness lighting while consuming relatively low power, ensuring that sufficient lighting intensity is provided to personnel in an emergency, helping them to quickly identify evacuation routes and safe exits. By rationally arranging a plurality of LED lamp beads, uniform distribution of light can be achieved, lighting blind spots can be avoided, and the overall effect of emergency lighting can be improved.

[0007] The light source panel preferably features an elongated strip design, facilitating wide spacing of the LED beads. LED beads generate heat during operation, and the elongated strip design facilitates natural convection and radiation heat dissipation. The wide spacing reduces thermal interference between beads, further improving heat dissipation, helping to extend the lifespan of the LED beads and maintain stable lighting output. The wide spacing of the LED beads reduces mutual interference between them, lowering the risk of cascading failures caused by overheating or damage. This design enhances the reliability and durability of the entire emergency sign light.

[0008] Preferably, the light source panel is located behind the light guide plate, which is located behind the signboard. It adopts a high-efficiency LED light source, combined with an optimized optical design, to ensure clear and uniform lighting effects in emergency situations and guide people to evacuate safely.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] 1. The wiring cavity of this utility model is tightly connected to the power cavity, which is then connected to the emergency lighting fixture, forming a compact and stable structure. A mounting bracket is provided on each side of the emergency lighting fixture for flexible installation.

[0011] 2. The power supply cavity of this utility model innovatively houses a first and second battery pack, each independent and providing backup for the other. This design significantly reduces the risk of the entire emergency lighting system being paralyzed due to failure of a single battery pack, thereby improving the system's reliability and durability. A protective plate is placed between the first and second battery packs. If one battery pack is impacted, the other is protected by the plate, enhancing the reliability and durability of the utility model and reducing the risk of backup power failure.

The power cavity 2 innovatively provides a first battery pack 22 and a second battery pack 24, which are independent of each other and serve as backups for each other. This design greatly reduces the risk of the entire emergency lighting system being paralyzed due to the failure of a single battery pack, and improves the reliability and durability of the system. A protective plate 23 is set between the first battery pack 22 and the second battery pack 24. When one of the battery packs is impacted, the other battery pack will be protected by the protective plate 23, which improves the reliability and durability of the present invention and reduces the risk of failure of the backup power supply.

[0025] The compression nut 11 is a three-section design, including a sealing gasket 111, an external thread 112, and a hexagonal nut 113, which can effectively seal and prevent external gas from penetrating, thereby enhancing the protection of the two battery packs and preventing the explosion shock wave from directly acting on the two battery packs and causing a secondary accident.

[0026] A plurality of LED lamp beads 311 are provided on the light source board 31.
