Description

Technical Field

[0001] This invention belongs to the field of fire emergency light technology, and specifically discloses a portable fire emergency light. Background Technology

[0002] Fire evacuation indicator lights are a type of fire emergency light. According to my country's "Technical Standard for Fire Emergency Lighting and Evacuation Indication System", fire evacuation indicator lights (marked with arrows or the words "safety exit") are in a power-saving lighting mode (i.e., always on but with low brightness) when not in a fire. In the event of a fire, they automatically switch to a fully lit emergency state to ensure that personnel are familiar with the evacuation route and to facilitate daily maintenance and management.

[0003] In order to meet the requirements of energy conservation and environmental protection, a solar-powered fire evacuation indicator light has appeared on the market. The fire evacuation indicator light is mainly composed of a lamp body and a conductive structure. In actual use, the conductive structure is connected to the solar power supply structure and the lamp body, thereby realizing the transmission of electrical energy generated by the solar power supply structure to the lamp body.

[0004] However, while this solar-powered fire evacuation indicator light does provide a good evacuation effect in actual use, it still has some shortcomings, such as:

[0005] Currently, most solar-powered fire evacuation indicator lights on the market rely on external power to provide warnings and illumination. When a fire cuts off the power supply to the solar-powered fire evacuation indicator light, it can only work by relying on its own stored power. This reduces the lifespan of the solar-powered fire evacuation indicator light, making it unable to continue providing warnings to evacuees. This leads to a greater risk to evacuees. In use, solar-powered fire evacuation indicator lights mainly rely on external power and do not have a good self-protection mechanism. When flames burn the solar-powered fire evacuation indicator light, the internal energy storage structure may explode, which can easily burn evacuees in the vicinity.

[0006] Meanwhile, solar-powered fire evacuation indicator lights are usually fixedly installed in a certain part of the fire lane, which makes them susceptible to external damage. When temporary evacuation is needed in areas where the flames have not reached, the fixedly installed solar-powered fire evacuation indicator lights cannot be moved at any time according to the site environment, which means that the solar-powered fire evacuation indicator lights cannot play their due role in evacuation. Summary of the Invention

[0007] In view of this, the purpose of the present invention is to provide a portable and mobile fire emergency light to solve the problems mentioned above.

[0008] To achieve the above objectives, the present invention provides a portable fire emergency light, including a reflective shell and a light-transmitting plate mounted on the reflective shell. The reflective shell contains lamp tubes, the power terminals of which are connected to an external power source. The light-transmitting shell is integrally fixed to the light-transmitting plate, and a light guide sheet is embedded inside the light-transmitting shell.

[0009] The light-transmitting plate, light guide sheet, and light-transmitting shell are all light-transmitting. The surface of the light-transmitting plate is frosted. The light guide sheet absorbs heat, which causes the light-transmitting shell to break off from the light-transmitting plate, thus exposing the inner cavity of the reflective shell.

[0010] An outer tube is integrally fixed to the outside of the lamp tube, and a highly thermally conductive metal mesh is placed between the outer tube and the lamp tube. The lamp tube can absorb heat and cause the outer tube and the lamp tube to break.

[0011] A through-tube runs through the reflective shell, and a light guide strip is embedded inside the through-tube. A protective sleeve is fitted onto one end of the light guide strip near the light-transmitting plate. Both the protective sleeve and the light guide strip are fixed on the light guide sheet. A conductive optical fiber is fixed to the outer end of the light guide strip, and a sunlight collector is connected to the conductive optical fiber.

[0012] In the above technical solution, a water collection shell is further fixed on one side of the reflective shell. The water receiving end of the water collection shell is connected to the fire water pipe. A water guide pipe is fixed on the water outlet end of the water collection shell. The water guide pipe passes through the reflective shell and is sleeved on the outer pipe. Multiple water guide plates are irregularly distributed inside the reflective shell. The water guide plates have a paddle-shaped structure. The water receiving part of the water guide plate faces the water guide pipe, and the drainage end of the water guide plate faces the light-transmitting shell.

[0013] In the above technical solution, the inner walls of the reflective shell, the through tube, and the protective sleeve are coated with a reflective coating. There is a gap between the through tube and the protective sleeve. The light-transmitting shell has a hole near the light guide strip. The protective sleeve and the light guide strip pass through the hole on the light-transmitting shell and the light guide sheet.

[0014] In the above technical solution, a battery pack is further fixed at the opposite part of the reflective shell and the water guide pipe. The power terminal of the battery pack is connected to an external power source. A conductive seat is fixed at the conductive end of the battery pack, and the conductive seat is sleeved on the conductive end of the lamp tube.

[0015] In the above technical solution, a fixing frame is further fitted onto the light-transmitting plate, and a mounting plate is abutted against the side of the fixing frame near the reflective shell, and the mounting plate is fixed on the reflective shell.

[0016] In the above technical solution, the fixing frame is further fixed by bolts and mounting plate, and a sealing strip is fixed on the mounting plate, the sealing strip being embedded between the mounting plate and the fixing frame.

[0017] In the above technical solution, further, an embedded piece is fixed on the side of the mounting plate away from the light-transmitting plate, the embedded piece is distributed on the four sides of the mounting plate, a bracket is fixed on the embedded piece at the bottom, and a roller is connected to the lower part of the bracket.

[0018] In the above technical solution, the outer tube is a tubular structure with a smooth outer wall, the lamp tube is a cylindrical structure, and the axes of the outer tube and the lamp tube coincide.

[0019] In the above technical solution, the lamp tube does not generate heat, and part of the light emitted by the lamp tube passes through the protective sleeve and the through tube and enters the interior of the light guide strip.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In actual use, the emergency light can prevent external power from transmitting electrical energy to the lamp tube. At this time, the sunlight collector can transmit sunlight to the light-transmitting shell, so that the pattern formed by the light guide plate can indicate the evacuation personnel, thus achieving a good energy-saving effect for the emergency light.

[0022] 2. When the staff provides power to the lamp tube, the light generated by the lamp tube will be transmitted to the light-transmitting shell through the light guide strip, so that the pattern formed by the light guide sheet can also indicate the evacuation personnel, and the emergency light can be used normally in a variety of environments.

[0023] 3. When a fire occurs around the emergency light, the light guide plate can absorb heat, causing the light-transmitting shell to crack. The outer tube can extend the service life of the lamp tube and continue to provide the light needed for evacuation. At the same time, the high thermal conductivity metal mesh absorbs heat and transfers it to the outer tube and lamp tube. When the outer tube 7 and lamp tube 72 absorb heat and crack, the emergency light can avoid giving incorrect directions to evacuation personnel.

[0024] 4. When the outer pipe and lamp tube are damaged, the water inside the fire water pipe will enter the interior of the reflective shell through the water guide pipe. The water can then cool the environment inside the evacuation space and ensure the safety of evacuees. Attached Figure Description

[0035] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0037] Example 1: Please refer to Figure 1-9 As shown, the present invention provides a technical solution:

[0038] The present invention is a portable fire emergency light, including a reflective shell 36 and a light-transmitting plate 33 mounted on the reflective shell 36. The reflective shell 36 has lamp tubes 72 distributed inside, and the power terminals of the lamp tubes 72 are connected to an external power source. A light-transmitting shell 34 is integrally fixed on the light-transmitting plate 33, and a light guide sheet 35 is embedded inside the light-transmitting shell 34.

[0039] In actual use, the staff can move the emergency light to a suitable position before the flame arrives. The light generated by the lamp tube 72 will illuminate the inside of the reflective shell 36. The inside of the reflective shell 36 is coated with a reflective coating, which allows the light inside the reflective shell 36 to be transmitted to the light guide 35, the light-transmitting shell 34 and the light-transmitting plate 33 through the reflective coating. In order to achieve a better indication effect for the emergency light, the light guide 35 should be selected as a light-transmitting sheet structure with easily distinguishable colors. The shape of the light guide 35 can be arrow-shaped, number-shaped, text-shaped or other sheet-shaped structures with indication effect.

[0040] The light-transmitting plate 33, the light guide plate 35, and the light-transmitting shell 34 are all light-transmitting, and the surface of the light-transmitting plate 33 is frosted.

[0041] In order to make it easier for evacuees to observe the indication information provided by the light guide plate 35, the light guide plate 35 and the light-transmitting shell 34 should be made of high light-transmitting materials. At the same time, the surface of the light-transmitting plate 33 is set to a frosted structure, so that the brightness of the light passing through the light-transmitting plate 33 is lower than the brightness of the light passing through the light guide plate 35 and the light-transmitting shell 34, thereby making it easier for evacuees to quickly obtain indication information through the light guide plate 35.

[0042] Example 2: Please refer to Figure 1-9 As shown, based on Embodiment 1, the present invention provides a technical solution. Unlike Embodiment 1, the light guide sheet 35 in this embodiment can absorb the heat transferred from the flame to the air and transfer it to the light-transmitting shell 34, thereby causing the light-transmitting shell 34 to break from the light-transmitting plate 33. This prevents the damaged light guide sheet 35 from providing guidance information to evacuees and avoids evacuees from entering dangerous evacuation routes.

[0043] The heat absorption of the light guide plate 35 can cause the light-transmitting shell 34 to break off from the light-transmitting plate 33, thus exposing the inner cavity of the reflective shell 36.

[0044] In the event of a fire, to prevent the emergency light from misleading evacuees, the light guide 35 is made of high-transmittance glass with a locally vapor-deposited infrared absorption film. Meanwhile, the light-transmitting shell 34 is made of pre-scratched soda-lime glass with a transparent explosion-proof film on the inside. This allows the flame radiation to be quickly absorbed by the local infrared absorption film on the light guide 35 when the flame is about to reach the vicinity of the emergency light, and the heat is directly conducted to the pre-scratched area of ​​the light-transmitting shell 34, forming a local thermal shock. This causes the light-transmitting shell 34 to break from the light-transmitting plate 33, thus preventing the damaged light guide 35 from providing guidance information to evacuees and avoiding them from entering dangerous evacuation routes.

[0045] Example 3: Please refer to Figure 1-9As shown, based on Embodiment 2, this invention provides a technical solution. Unlike Embodiment 2, in this embodiment, the outer tube 7 provides better protection for the lamp tube 72, and the high thermal conductivity metal mesh 71 can quickly absorb heat from the fire environment and evenly transfer it to the glass tube wall. When the ambient temperature reaches the glass's thermal stress limit, the outer tube 7 and lamp tube 72 will rupture controllably due to thermal stress concentration, causing the lamp tube 72 circuit to be interrupted and stop emitting light, thereby avoiding providing incorrect instructions to evacuees in extreme situations.

[0046] An outer tube 7 is integrally fixed to the outside of the lamp tube 72. A high thermal conductivity metal mesh 71 is placed between the outer tube 7 and the lamp tube 72. The high thermal conductivity metal mesh 71 is made of a metal material with good heat absorption, such as copper or aluminum alloy. Both the outer tube 7 and the lamp tube 72 are heat-sensitive explosion glass that breaks when heated.

[0047] When evacuees reach the location of the emergency light, the light-transmitting shell 34 may break. At this time, the evacuees need to return to the safe evacuation route. In order to enable the emergency light to continue to illuminate the evacuees during the return process, the lamp tube 72 is provided with an outer tube 7. In actual use, the outer tube 7 can provide good protection for the lamp tube 72 and extend the service life of the lamp tube 72 in flames.

[0048] To prevent the lamp tube 72 from providing incorrect guidance information to evacuees, a high thermal conductivity metal mesh 71 is placed between the lamp tube 72 and the outer tube 7. The high thermal conductivity metal mesh 71 can be made of a metal material with good heat absorption available on the market. When the high thermal conductivity metal mesh 71 absorbs heat from the fire environment, it will transfer the heat to the walls of the outer tube 7 and the lamp tube 72, thereby causing the outer tube 7 and the lamp tube 72 to break in a controllable manner due to thermal stress concentration. The lamp tube 72 will then be unable to continue transmitting light, thus preventing the lamp tube 72 from providing incorrect guidance information to evacuees.

[0049] Example 4: Please refer to Figure 1-9 As shown, based on Embodiment 1, the present invention provides a technical solution. Unlike Embodiment 1, the sunlight collector 1 in this embodiment can collect sunlight and provide a light source to the light guide plate 35 through the transmission optical fiber 2 and the light guide strip 61, thereby enabling the light guide plate 35 to provide warning information to evacuees. This can effectively avoid the risk of circuit hazards around the emergency light when a fire occurs.

[0050] A through-tube 6 runs through the reflective shell 36. A light guide strip 61 is embedded inside the through-tube 6. A protective sleeve 62 is sleeved on one end of the light guide strip 61 near the light-transmitting plate 33. Both the protective sleeve 62 and the light guide strip 61 are fixed on the light guide sheet 35. A conductive optical fiber 2 is fixed on the outer end of the light guide strip 61. A sunlight collector 1 is connected to the conductive optical fiber 2.

[0051] In normal use, in order to make the emergency light more energy-efficient, the staff can prevent the external power supply to the inside of the lamp tube 72. The sunlight collector 1 can collect sunlight and provide a light source to the light guide plate 35 through the optical fiber 2 and the light guide strip 61, so that the light guide plate 35 can provide warning information to evacuees. The advantage of this design is that it can effectively avoid the risk of circuits around the emergency light in the event of a fire.

[0052] The solar collector 1 and the optical fiber 2 are available on the market and are products well known to those skilled in the art.

[0053] Example 5: Please refer to Figure 1-9 As shown, based on Embodiment 3, the present invention provides a technical solution. Unlike Embodiment 3, in this embodiment, the outer pipe 7 can block the water outlet of the water guide pipe 51. When the outer pipe 7 breaks due to thermal stress concentration, the outer pipe 7 can no longer block the water outlet of the water guide pipe 51. This allows the water inside the fire water pipe to be discharged through the water guide pipe 51. Subsequently, the water inside the reflective shell 36 will be discharged through the gap in the broken light-transmitting shell 34, thereby cooling the air around the emergency light with fire water.

[0054] A water collection shell 5 is fixed to one side of the reflective shell 36. The water inlet end of the water collection shell 5 is connected to the fire water pipe. A water guide pipe 51 is fixed to the water outlet end of the water collection shell 5. The water guide pipe 51 passes through the reflective shell 36 and is sleeved on the outer pipe 7. Multiple water guide plates 38 are irregularly distributed inside the reflective shell 36. The water guide plates 38 have a paddle-shaped structure. The water inlet of the water guide plate 38 faces the water guide pipe 51, and the drain end of the water guide plate 38 faces the light-transmitting shell 34.

[0055] When evacuees reach the vicinity of the emergency light, they may not be able to enter a safe evacuation space in time. In order to delay the entry of flames or thick smoke into the vicinity of the emergency light, the water inlet of the water collection shell 5 is connected to the fire water pipe. Under normal use, the outer pipe 7 can block the outlet of the water guide pipe 51. When the outer pipe 7 breaks, the outer pipe 7 can no longer block the outlet of the water guide pipe 51. This allows the water inside the fire water pipe to be discharged through the water guide pipe 51. It should be noted that the fire water pipe shown in this document is a fire water pipe reserved inside the building. The fire water pipe is connected to an external control valve. The control valve of the fire water pipe is connected to the external fire protection system. When a fire occurs inside the building, the external fire protection system will control the external control valve on the fire water pipe to work, thereby allowing the water inside the fire water pipe to be discharged through the water guide pipe 51. Subsequently, the water inside the reflective shell 36 will be discharged through the gap of the broken light-transmitting shell 34, thereby cooling the air around the emergency light with fire water.

[0056] It should be noted that when fire-fighting fluid is discharged from the gap in the broken light-transmitting shell 34, the fire-fighting fluid may carry debris from the light-transmitting plate 33, light guide plate 35, light-transmitting shell 34, outer tube 7, and lamp tube 72 into the interior of the evacuation space. In order to avoid these debris from causing harm to evacuees, the light-transmitting plate 33, light guide plate 35, light-transmitting shell 34, outer tube 7, and lamp tube 72 need to be made of fire-safe certified materials.

[0057] When the water inside the fire hose is discharged into the interior of the reflective shell 36 through the water guide pipe 51, the water guide plate 38 can block the water discharged from the water guide pipe 51 and slow down the speed of the water discharged from the broken gap of the light-transmitting shell 34. At the same time, the water guide plate 38 has a paddle-shaped structure. When the water discharged from the water guide pipe 51 is discharged through the broken gap of the light-transmitting shell 34, the water guide plate 38 can drive the water flow to turbulence, which can prevent the water discharged from the reflective shell 36 from spraying out. It further prevents the water from spraying out the broken debris of the light-transmitting plate 33, light guide plate 35, light-transmitting shell 34, outer pipe 7 and lamp tube 72, ensuring the safety of personnel inside the evacuation space.

[0058] It should be noted that when the light-transmitting plate 33 is in operation, it needs to meet the characteristics of high temperature resistance and breakage resistance. This ensures that the water discharged from the reflective shell 36 can only be discharged through the gaps in the broken light-transmitting shell 34.

[0059] Example 6: Please refer to Figure 1-9 As shown, based on Embodiment 4, the present invention provides a technical solution. Unlike Embodiment 4, in this embodiment, a gap is provided between the through tube 6 and the protective sleeve 62. This allows some of the light inside the light guide strip 61 to reach the interior of the reflective shell 36, while the other light inside the light guide strip 61 is transmitted to the light guide sheet 35. The reflective coating inside the reflective shell 36 can transmit the light leaking out of the light guide strip 61 to the light-transmitting plate 33, so that the light guide sheet 35 can provide a better indication effect for evacuating personnel.

[0060] The inner walls of the reflective shell 36, the through tube 6 and the protective sleeve 62 are coated with a reflective coating. There is a gap between the through tube 6 and the protective sleeve 62. The light-transmitting shell 34 has a hole near the light guide strip 61. The protective sleeve 62 and the light guide strip 61 pass through the hole on the light-transmitting shell 34 and the light guide sheet 35.

[0061] In order to enable the emergency light to be used in a sunny condition, a gap is provided between the through tube 6 and the protective sleeve 62. This allows some of the light inside the light guide strip 61 to reach the interior of the reflective shell 36, while the other light inside the light guide strip 61 will be transmitted to the light guide plate 35. The reflective coating inside the reflective shell 36 can transmit the light leaking out of the light guide strip 61 to the light-transmitting plate 33.

[0062] It should be noted that when light is transmitted inside the light guide strip 61, the light leaking out of the light guide strip 61 will be darker than the light normally transmitted inside the light guide strip 61. This explains why the reflective coating inside the reflective shell 36 transmits darker light to the light-transmitting plate 33 than the light transmitted by the light guide strip 61 to the light guide sheet 35. As a result, the light guide sheet 35 can provide a better indication effect for evacuating personnel.

[0063] A battery pack 4 is fixed at the opposite part of the reflector shell 36 and the water pipe 51. The battery pack 4 can be purchased from the market. The power terminal of the battery pack 4 can be connected to an external power source. A conductive seat 41 is fixed at the conductive end of the battery pack 4. The conductive seat 41 is sleeved on the conductive end of the lamp tube 72.

[0064] When the emergency light is not used with sunlight, an external power source can provide power to the lamp tube 72, thereby enabling the light guide plate 35 to work normally. It should be noted that when the external power source provides power to the lamp tube 72, the battery pack 4 needs to be connected to a leakage protection structure. This can prevent the emergency light from experiencing circuit risks in the event of a fire.

[0065] A fixing frame 32 is fitted onto the light-transmitting plate 33. The fixing frame 32 abuts against the mounting plate 3 on the side near the reflective shell 36. The mounting plate 3 is fixed on the reflective shell 36.

[0066] The fixed frame 32 is fixed by bolts and mounting plate 3. A sealing strip 37 is fixed on the mounting plate 3 and is embedded between the mounting plate 3 and the fixed frame 32.

[0067] An insert 31 is fixed on the side of the mounting plate 3 away from the light-transmitting plate 33. The insert 31 is distributed on the four sides of the mounting plate 3. A bracket 8 is fixed on the insert 31 at the bottom. A roller 81 is connected to the lower part of the bracket 8.

[0068] When the emergency light is in use, the bracket 8 can move the emergency light to a suitable position by using the roller 81, which can facilitate the light guide plate 35 in the emergency light to provide a better indication effect for evacuees. The embedded plate 31 can protect the battery pack 4 and the water collection shell 5 to prevent the emergency light from being damaged by external impact. The roller 81 can be selected as a self-locking universal wheel that is available on the market.

[0069] A sealing strip 37 is embedded between the mounting plate 3 and the fixing frame 32 to prevent dense smoke from entering the interior of the reflective shell 36 in the event of a fire, thereby ensuring the normal operation of the internal structure of the reflective shell 36. It should be noted that the sealing strip 37 is made of halogen-free flame-retardant material. At the same time, when dense smoke enters the interior of the reflective shell 36, the high thermal conductivity metal mesh 71 absorbs heat in advance and transfers it to the outer tube 7 and the lamp tube 72, causing the outer tube 7 and the lamp tube 72 to absorb heat and break.

[0070] The outer tube 7 has a tubular structure and its outer wall is smooth. The lamp tube 72 has a cylindrical structure and the axes of the outer tube 7 and the lamp tube 72 coincide.

[0071] The lamp tube 72 does not generate heat, which can prevent the heat generated by the lamp tube 72 from being transferred to the high thermal conductivity metal mesh 71. Part of the light emitted by the lamp tube 72 passes through the protective sleeve 62 and the through tube 6 and enters the interior of the light guide strip 61, which can make the brightness of the light guide sheet 35 greater than the brightness of the light-transmitting plate 33.

[0072] Working principle: When the emergency light is in use, the bracket 8 can move the emergency light to a location not reached by the flame through the roller 81, which makes it easier for the light guide plate 35 in the emergency light to provide a better indication effect for evacuees. Then, the staff can stop the external power supply from transmitting electrical energy to the lamp tube 72. At this time, the sunlight collector 1 can transmit sunlight to the light-transmitting shell 34, so that the pattern formed by the light guide plate 35 can indicate the evacuees, and the emergency light has a good energy-saving effect.

[0073] When the staff provides power to the lamp tube 72, the light generated by the lamp tube 72 will be transmitted to the light-transmitting shell 34 through the light guide strip 61, so that the pattern formed by the light guide sheet 35 can also indicate the evacuation personnel, and the emergency light can be used normally in a variety of environments.

[0074] When a fire occurs around the emergency light, the light guide plate 35 can absorb heat, causing the light-transmitting shell 34 to crack. The outer tube 7 can extend the service life of the lamp tube 72 and continue to provide the light needed for evacuation. At the same time, the high thermal conductivity metal mesh 71 absorbs heat and transfers it to the outer tube 7 and the lamp tube 72. When the outer tube 7 and the lamp tube 72 absorb heat and crack, the emergency light can avoid giving incorrect directions to evacuation personnel.

[0075] When the outer pipe 7 and the lamp tube 72 are damaged, the water inside the fire water pipe will enter the interior of the reflective shell 36 through the water guide pipe 51. At this time, the fire water will come into contact with the light guide strip 61, and sunlight can reach any position in the evacuation space through the fire water, thus making it easier for evacuees to quickly find the evacuation route by sunlight. At the same time, the water can cool the environment inside the evacuation space and ensure the safety of evacuees.

[0076] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.

A transmission optical fiber is fixed to the outer end of the light guide strip, and a sunlight collector is connected to the transmission optical fiber. A water collection shell is fixed on one side of the reflective shell. The water inlet end of the water collection shell is connected to the fire water pipe. A water guide pipe is fixed on the water outlet end of the water collection shell. The water guide pipe passes through the reflective shell and is sleeved on the outer pipe. Multiple water guide plates are irregularly distributed inside the reflective shell. The water guide plates have a paddle-shaped structure. The water inlet of the water guide plate faces the water guide pipe, and the water outlet end of the water guide plate faces the light-transmitting shell. The inner walls of the reflective shell, the through tube, and the protective sleeve are coated with a reflective coating. There is a gap between the through tube and the protective sleeve. The light-transmitting shell has a hole near the light guide strip. The protective sleeve and the light guide strip pass through the hole on the light-transmitting shell and the light guide sheet. The lamp tube does not heat up; some of the light emitted by the lamp tube passes through the protective sleeve and the through tube and enters the interior of the light guide strip. Under normal use, the outer tube can block the outlet of the water pipe. However, in the event of a fire, the high thermal conductivity metal mesh absorbs heat. When the ambient temperature reaches the thermal stress limit of the glass, the outer tube and the lamp tube break. To prevent the lamp tube from transmitting incorrect information to evacuees, the outer tube can no longer block the outlet of the water pipe. The water inside the fire water pipe is discharged through the water pipe, and the water inside the reflective shell will be discharged through the gap in the broken light-transmitting shell, thus achieving cooling.
