Description

Technical Field

[0001] This invention relates to the field of lighting fixtures, and in particular to a fire emergency lighting fixture. Background Technology

[0002] Fire emergency lights are common equipment in fire emergency systems. They provide illumination when the normal lighting power supply fails (such as a power outage caused by a fire) and are often used in densely populated or dimly lit environments such as evacuation corridors, stairwells, and underground garages.

[0003] The key to fire emergency lights being able to provide illumination during power outages lies in their internal power supply. When a power outage occurs, the internal power supply provides power to keep the lamp head lit. In existing fire emergency lights, the lamp head is fixed to the chassis with rivets. When the lamp head fails, it cannot be disassembled separately, and the entire emergency light needs to be replaced, resulting in high equipment maintenance costs. Furthermore, since the number of lamp heads and their installation positions are fixed, users cannot increase or decrease the number of lamp heads according to actual usage needs. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fire emergency lighting fixture with a detachable lamp head that can be replaced or added to reduce maintenance costs. At the same time, it allows users to increase or decrease the number of lamp heads according to the actual usage scenario.

[0005] The objective of this invention is achieved through the following technical solution: A fire emergency lighting fixture includes: a light box, a lamp holder, a connector, a panel, a control board, and a battery; The panel, the control board, and the battery are all located inside the light box. The panel and the battery are electrically connected to the control board. The panel is equipped with buttons located on the front of the light box. The connector is detachably mounted on the light box, the lamp head is located on the connector, and the lamp head and the connector are rotatably connected. The control board is provided with wires that extend to the outside of the light box and are electrically connected to the lamp head. The button is used to control the lamp head to light up or turn off.

[0006] In one embodiment, the back of the light box is provided with a fixing frame, the fixing frame is provided with a gourd-shaped hanging hole, the gourd-shaped hanging hole is provided with a connected avoidance part and a stop part, the diameter of the stop part is smaller than the diameter of the avoidance part.

[0007] In one embodiment, the light box has an electrical connector on its side.

[0008] In one embodiment, the connecting base includes a bracket and a locking pin. The locking pin is rotatably mounted on the bracket, and a wiring hole is provided on the bracket near the locking pin. A dustproof locking buckle is provided at the position where the light box contacts the bracket. The dustproof locking buckle is integrally formed with the light box. When the dustproof locking buckle is extended, it blocks the light box. The locking pin is used to drive the dustproof locking buckle to bend and to make the dustproof locking buckle abut against the side of the locking pin. The side of the locking pin has a slot and a light-emitting surface. The dustproof locking buckle abuts against the slot to lock the bracket and the light box together. When the dustproof locking buckle abuts against the light-emitting surface, it releases the lock on the bracket and the light box.

[0009] In one embodiment, the position on the light box that contacts the bracket is a mounting position, and the light box has three mounting positions.

[0010] In one embodiment, each of the mounting positions is provided with two dustproof locking buckles, the number of which is the same as the number in the connecting seat.

[0011] In one embodiment, the end of the locking pin is provided with a wrench position and a marking.

[0012] In one embodiment, a gap is provided between the dustproof locking buckle and the light box.

[0013] In one embodiment, the lamp head includes a housing, a light source plate, a reflector, and a lampshade. The inner cavity of the housing is provided with a limiting rib and a positioning buckle. The light source plate is provided with an outward protrusion that matches the limiting rib. The positioning buckle is fastened to the light source plate.

[0014] In the aforementioned fire emergency lighting fixtures, the lamp head is mounted on a connector, and the connector and the light box are detachably connected, allowing the lamp head to be removed, replaced, or added or removed, reducing maintenance costs. At the same time, it allows users to increase or decrease the number of lamp heads according to the actual usage scenario. Attached Figure Description

[0021] Please see Figure 1 and Figure 2 The present invention provides a fire emergency lighting fixture 10, which includes: a light box 100, a lamp holder 200, a connector 300, a panel 400, a control board 500, and a battery 600.

[0022] Please see Figure 1 and Figure 2 The panel 400, control board 500, and battery 600 are all located inside the light box 100. The panel 400 and battery 600 are electrically connected to the control board 500. The panel 400 is equipped with a button 410, which is located on the front of the light box 100. When the external power supply is normal, the control board 500 drives the lamp head 200 to be in the off state. When a power outage occurs, the control board 500 sends a signal to drive the battery 600 to supply power to the lamp head 200, so that the fire emergency lighting fixture 10 can provide lighting in the event of an external power outage.

[0023] Please see Figure 1 and Figure 4 The connector 300 is detachably mounted on the light box 100, the lamp head 200 is located on the connector 300, and the lamp head 200 and the connector 300 are rotatably connected. The control board 500 is provided with wires that extend to the outside of the light box 100 and are electrically connected to the lamp head 200. The button 410 is used to control the lamp head 200 to light up or turn off.

[0024] In the aforementioned fire emergency lighting fixture 10, the lamp head 200 is mounted on the connector 300, and the connector 300 and the light box 100 are detachably connected, so that the lamp head 200 can be detached, replaced or added, reducing maintenance costs, and allowing users to increase or decrease the number of lamp heads 200 according to the actual usage scenario.

[0025] It should be noted that in the existing fire emergency lighting fixture 1, the lamp head 200 and the light box 100 are fixed together by riveting or welding, which makes the lamp head 200 more secure, but also makes it difficult to remove the lamp head 200 from the light box 100. The lamp holder 200 is a vulnerable component. Aging of the lamp panel and moisture in the environment can cause the lamp holder 200 to fail to light up or become dim. If the user discovers a faulty lamp holder 200 during maintenance, the faulty lamp needs to be replaced. Since the lamp holder 200 in existing fire emergency lighting fixtures is fixed together with the light box 100, the entire lamp needs to be replaced when the lamp holder 200 fails to provide lighting, resulting in high maintenance costs. On the other hand, most existing fire emergency lighting fixtures use a design with two lamp holders 200, both of which light up simultaneously to provide illumination. However, in actual use, such as in narrow passages like stairwells, a single lamp holder 200 is sufficient to meet temporary lighting needs. Adding more lamp holders 200 increases the power consumption of the lamp, and users cannot adjust the number of lamp holders 200 according to the actual usage scenario of the emergency light, which is inconvenient during use.

[0026] Please see Figure 4 and Figure 7 To solve the above problems, the connector 300 includes a bracket 310 and a locking pin 320. The locking pin 320 is rotatably mounted on the bracket 310, and a wiring hole 311 is provided on the bracket 310 near the locking pin 320. A dustproof locking buckle 700 is provided at the position where the light box 100 contacts the bracket 310. The dustproof locking buckle 700 is integrally formed with the light box 100.

[0027] The aforementioned dustproof locking buckle 700 is formed by a stamping process. The dustproof locking buckle 700 is elongated, with one end connected to the light box 100 and the other end separated from it, leaving a gap between them. When the dustproof locking buckle 700 is subjected to pressure, the end separated from the light box 100 can bend towards the inner cavity of the light box 100, such as... Figure 8 As shown; and after pulling out the locking pin 320, pressing it with force can drive the dustproof lock buckle 700 back to its flat position, as... Figure 7 As shown, this is to maintain the airtightness of the light box 100. The process of bending the dustproof lock 700 and applying force to restore its flatness utilizes the plasticity of the metal component itself.

[0028] In this way, when the dustproof locking buckle 700 extends, it can block the light box 100, maintain the airtightness of the light box 100, and prevent foreign objects from entering the interior of the light box 100; when the lamp head 200 is fixed to the light box 100, the locking pin 320 drives the dustproof locking buckle 700 to bend, and after the locking pin 320 enters the interior of the light box 100, the dustproof locking buckle 700 abuts against the side of the locking pin 320.

[0029] Please see Figure 5 The locking pin 320 has a slot 321 and a smooth surface 322 on its side. The surface of the slot 321 is continuously concave and convex, and the smooth surface 322 is a smooth plane. Half of the side of the locking pin 320 is the slot 321 and the other half is the smooth surface 322. The dustproof lock buckle 700 abuts against the slot 321 to lock the bracket 310 and the light box 100 together. When the dustproof lock buckle 700 abuts against the smooth surface 322, the locking of the bracket 310 and the light box 100 is released. Rotating the locking pin 320 can switch between the locked and unlocked states, making the disassembly and assembly of the lamp head 200 easier.

[0030] Please see Figure 3 The location on the light box 100 that contacts the bracket 310 is the mounting position 20. The mounting position 20 serves as the fixing position for the lamp holder 200. Multiple mounting positions 20 can be configured on the light box 100, for example, three mounting positions 20. Each mounting position 20 contains two dustproof locking buckles 700, and the number of dustproof locking buckles 700 is the same as the number in the connecting seat 300. It should be noted that the mounting position 20 is the area enclosed by the dotted line in the figure; the mounting position 20 refers to the area on the light box 100 that contacts the bracket 310.

[0031] The specific working principle of the locking pin 320 and the dustproof locking buckle 700 in conjunction with the lamp holder 200 for disassembly and assembly is as follows: Before the lamp holder 200 and the lamp box 100 are assembled, all dustproof locks 700 are in the extended state, such as Figure 3 As shown.

[0032] Move the lamp holder 200 to the mounting position 20, adjust its position so that the locking pin 320 is aligned with the dustproof locking buckle 700, and press the locking pin 320 so that it extends into the light box 100. During this process, the end of the locking pin 320 drives the dustproof locking buckle 700 to bend towards the inner cavity of the light box 100. After the locking pin 320 extends into the light box 100, the end of the dustproof locking buckle 700 abuts against the side of the locking pin 320. The dustproof locking buckle 700 itself is elastic and maintains contact with the side of the locking pin 320 under its own elastic force.

[0033] In the above process, the slot 321 faces the dustproof lock buckle 700. Because the surface of the slot 321 is uneven, the end of the dustproof lock buckle 700 is locked after being inserted into the recessed position of the slot 321, thus fixing the locking pin 320 in its current position and preventing axial sliding. The slot 321 and the dustproof lock buckle 700 cooperate to fix the connecting seat 300 onto the light box 100, completing the locking of the lamp head 200. Figure 8 As shown, this can effectively improve the assembly efficiency of the lamp holder 200.

[0034] When lamp holder 200 malfunctions and needs replacement, simply rotate locking pin 320 180° so that the light-emitting surface 322 contacts dustproof locking buckle 700. At this point, the end of dustproof locking buckle 700 is no longer obstructed, and force can be applied to pull dustproof locking buckle 700 out of lamp housing 100. Figure 7 As shown, this is how the lamp holder 200 is removed from the lamp box 100.

[0035] Please see Figure 5 Preferably, the end of the locking pin 320 is provided with a wrench position 323 and a mark (not shown). The user inserts a hex wrench into the wrench position 323 to rotate the locking pin 320 and observes the mark on the locking pin 320 to distinguish the orientation of the slot 321 and the smooth surface 322.

[0036] As can be seen from the above, the locking pin 320 and the dustproof locking buckle 700 work together to lock the lamp holder 200. The disassembly and assembly process only requires rotating the locking pin 320 half a turn, without needing to continuously rotate it, making the disassembly and assembly of the lamp holder 200 convenient. At the same time, the dustproof locking buckle 700 itself is elastic. When the locking pin 320 is inserted into the light box 100, its own elastic force keeps it abutting against the side of the locking pin 320 to lock the lamp holder 200. When the locking pin 320 is removed from the light box 100, applying force to press the dustproof locking buckle 700 can restore it to its flat state, sealing any gaps caused by bending, thereby ensuring the airtightness of the light box 100.

[0037] It should be noted that after the locking pin 320 is inserted into the light box 100, the dustproof locking buckle 700 bends. A wiring hole 311 is provided on the bracket 310 near the locking pin 320. When the dustproof locking buckle 700 bends, it no longer blocks the wiring hole 311, and the bend provides space for wiring, allowing the wire to pass through the wiring hole 311 and connect electrically to the lamp holder 200. Furthermore, after the lamp holder 200 is fixed, the bracket 310 covers the mounting position 20, preventing external foreign objects from entering the light box 100 through the space provided by the dustproof locking buckle 700.

[0038] Furthermore, the light box 100 is equipped with multiple mounting positions 20, allowing users to increase or decrease the number of lamp heads 200 and adjust their mounting positions according to actual needs. Since the dustproof locking buckle 700 is integrally formed with the light box 100, and the metal components have good plasticity, after removing the lamp head 200, force can be applied to "straighten" the dustproof locking buckle 700 to reseal the light box 100, preventing external foreign objects from entering the interior of the light box 100.

[0039] The above-mentioned fire emergency lighting fixtures have the following beneficial effects: 1. The slot 321 on the side of the locking pin 320 cooperates with the dustproof lock buckle 700. The concave and convex structure on the slot 321 locks the dustproof lock buckle 700 to fix the bracket 310, thereby locking the lamp head 200. The lamp head 200 can be assembled without the aid of tools. Rotating the locking pin 320 so that the light surface 322 faces the dustproof lock buckle 700 will release the lock on the bracket 310. Force can be applied to the bracket to pull the locking pin 320 out of the lamp box 100, thereby removing the lamp head 200. Switching the locking state only requires driving the locking pin 320 to rotate 180°, making the assembly and disassembly process of the lamp head 200 simple and quick, which helps to improve maintenance efficiency.

[0040] 2. The lamp head 200 and the lamp box 100 are detachably connected. By rotating the locking pin 320, the orientation of the slot 321 and the light surface 322 can be adjusted to cooperate with the dustproof lock buckle 700 to lock and unlock the lamp head 200. During maintenance, the faulty lamp head 200 can be replaced separately to reduce maintenance costs.

[0041] 3. The light box 100 provides multiple mounting positions 20 as fixed positions for the lamp heads 200. Users can increase or decrease the number of lamp heads 200 according to actual usage needs, and can adjust the fixed position of the lamp heads 200 on the light box 100.

[0042] Please see Figure 6 In one embodiment, the lamp holder 200 includes a housing 210, a light source plate 220, a reflector 230, and a lampshade 240. The housing 210 has a limiting rib 211 and a positioning buckle 212 inside its cavity. The light source plate 220 has an outward protrusion that matches the limiting rib 211. The positioning buckle 212 engages with the light source plate 220. The limiting rib 211 and the outward protrusion provide lateral limiting for the light source plate 220. Since the positioning buckle 212 is used for fixing, screws are not needed to lock the light source plate 220, thus preventing damage to the light source plate 220 when screws are tightened.

[0043] Please see Figure 2 In one embodiment, a mounting bracket 110 is provided on the back of the light box 100. The mounting bracket 110 has a gourd-shaped hanging hole 111. The gourd-shaped hanging hole 111 has a connected clearance part and a stop part. The diameter of the stop part is smaller than the diameter of the clearance part. When fixing the fire emergency lighting fixture 10, a thumbtack is driven into the target position, and the light box 100 is hung on the wall by the thumbtack cooperating with the gourd-shaped hanging hole 111.

[0044] Please see Figure 1 In one embodiment, the light box 100 is provided with an electrical connector 120 on its side, which is connected to an external power source to charge the battery 600.

[0045] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
