Description

Technical Field

[0001] This utility model relates to the technical field of fire indicator lights, specifically to an adjustable waterproof indicator light with encapsulated wires. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] Emergency evacuation lighting fixtures are emergency lighting facilities used to indicate safety exits and evacuation directions. Their function is to provide clear evacuation route guidance for personnel in emergency situations, ensuring their safe and rapid evacuation. They are widely used in densely populated public places such as schools, shopping malls, hospitals, and subway stations, as well as in tunnels, residences, and civil defense projects.

[0004] In recent years, with the acceleration of urbanization, the construction of tunnels and rail transit has been increasing. Due to the special nature of the tunnel and rail transit environment, higher requirements have been placed on the functionality of emergency evacuation lighting. For example, in tunnels, the distance from the tunnel exit must be marked on the lighting fixtures so that drivers can adjust their settings in advance and avoid traffic accidents caused by delayed eye adaptation due to direct glare at the tunnel exit; furthermore, the normal operation of emergency evacuation lighting must be ensured in inclement weather such as rain and snow.

[0005] The inventors discovered that traditional meter markers typically have fixed distance values. While highly reliable, they require precise alignment with blueprints during on-site installation; otherwise, inaccurate distance information necessitates complete lamp replacement, increasing maintenance costs and installation difficulty. Digital tube meter markers, although allowing manual adjustment of distance information, suffer from unclear display, especially in tunnels with smoke or complex lighting conditions, failing to meet the need for rapid identification. Furthermore, the high power consumption of digital tubes impacts the overall effectiveness of the lighting fixture. Additionally, existing fixtures have gaps within the wire cores, making them susceptible to water ingress, potentially leading to circuit failures, safety hazards, and a failure to provide clear evacuation route guidance. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an adjustable waterproof meter marker light with encapsulated wires. It employs two independent self-made optical cavities to make the meter mark display clearer and facilitate maintenance. At the same time, the wires are processed to solve the problem of water ingress into the wire core. While ensuring the functionality of the light fixture, it improves the reliability of protection and the display effect.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] In the first aspect, an adjustable waterproof marker light with wire encapsulation is disclosed, comprising:

[0009] Front cover, back panel, sign display device and wire potting structure;

[0010] The back plate is disposed inside the front cover plate, and a sign display device is provided at the lower part between the front cover plate and the back plate;

[0011] The conductor potting structure includes power line segment A, power line segment B, power line connecting plate, potting groove, power line segment B fixing slot and connecting plate slot.

[0012] One end of power cord A extends out of the back plate to connect to the power supply, and the other end is connected to power cord B through the power cord connecting plate; power cord B is installed in the power cord B fixing slot; the power cord connecting plate is installed in the potting groove through the connecting plate slot; the potting groove is filled with waterproof potting compound.

[0013] As a further technical solution, the upper end of the back plate is provided with an integrated lamp bead control board, which includes a controller and a light source. The controller is used to control the on / off state of the light source.

[0017] The meter-scale display optical cavity consists of two optical cavities, each equipped with an optical isolation grid.

[0018] The meter display control board is equipped with mounting holes for LED beads and optical cavities.

[0019] As a further technical solution, the optical cavity fixing post of the meter display optical cavity is inserted into the optical cavity mounting hole of the meter display control board and fixed by heating with a soldering iron.

[0020] As a further technical solution, both the back plate and the front cover are box-shaped, and the outer wall of the back plate matches the inner wall of the front cover.

[0021] As a further technical solution, a cable outlet hole is provided at the lower end of the back plate for the power cable section A to extend out.

[0022] As a technical solution, a light diffusion plate is provided between the back plate and the front cover plate; a sealing gasket is also provided between the light diffusion plate and the back plate.

[0023] As a further technical solution, the upper part of the light diffusion plate is provided with a light-transmitting area corresponding to the light-transmitting area marked by the arrow, and the lower part of the light diffusion plate is provided with two light-transmitting windows corresponding to the light-transmitting area marked by the numbers.

[0024] As a further technical solution, the front cover plate is provided with a plurality of fixing studs; the light diffusion plate, the back plate and the sealing gasket are respectively provided with mounting holes that match the fixing studs; the front cover plate, the light diffusion plate, the sealing gasket and the back plate are sequentially fixedly connected by screws and fixing studs.

[0025] One or more technical solutions of this utility model have the following beneficial effects:

[0026] In this embodiment, a meter-marked display cavity replaces the traditional digital tube, increasing the size of the meter-marked digital display and making the display clearer. This overcomes the high power consumption of the digital tube and improves the overall performance of the lamp. Combined with a light isolation grid, it ensures uniform digital brightness and no halo interference, enabling clear identification even in complex environments such as smoke or light.

[0040] Where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0041] Example 1

[0042] like Figures 1-5As shown, in this embodiment, an adjustable meter-marker waterproof indicator light with wire potting is provided, comprising:

[0043] Front cover 1, back plate 11, sign display device and wire potting structure;

[0044] A back plate 11 is provided inside the front cover 1, and a sign display device is provided at the lower part between the front cover 1 and the back plate 11.

[0045] The conductor potting structure includes power line A section 4, power line B section 6, power line connecting plate 5, potting groove 15, power line B section fixing slot 16 and connecting plate slot 17.

[0046] One end of power cord A section 4 extends out of back plate 11 to connect to the power supply, and the other end is connected to power cord B section 6 through power cord connecting plate 5; power cord B section 6 is installed in power cord B section fixing slot 16, and power cord connecting plate 5 is installed in potting groove 15 through connecting plate slot 17; the potting groove 15 is filled with waterproof potting compound.

[0047] like Figure 2 , Figure 3 As shown, in this embodiment, the surface of the sign light is a one-piece structure, with both the front cover plate 1 and the back plate 11 being box-shaped, and the inner wall of the front cover plate 1 and the outer wall of the back plate 11 fitting together. This effectively improves the dustproof, waterproof, and moisture-proof performance of the sign light.

[0048] Furthermore, the front cover plate 1 can be made of high-strength materials such as stainless steel or aluminum alloy, which can effectively fix the sign light and ensure its long-term use.

[0049] The backplate 11 can be a one-piece injection molded backplate.

[0050] like Figure 1 As shown in this embodiment, the front cover plate 1 has an arrow-marked light-transmitting area at the top and a number-marked light-transmitting area at the bottom. The arrow-marked light-transmitting area is used to indicate the direction of drainage, and the number-marked light-transmitting area is used to indicate the distance from the outlet.

[0051] like Figure 1 As shown, in this embodiment, a light diffusion plate 2 is also provided between the front cover plate 1 and the back plate 11; a sealing gasket 3 is also provided between the light diffusion plate 2 and the back plate 11. The sealing gasket 3 has a protection rating of up to IP68.

[0052] The light diffusion plate 2 has a light-transmitting area at the top corresponding to the light-transmitting area marked by the arrow, and two light-transmitting windows at the bottom corresponding to the light-transmitting areas marked by numbers. The light diffusion plate 2 further improves the uniformity of light transmission.

[0053] like Figure 1 , Figure 5As shown, in this embodiment, a mark display device is provided between the front cover plate 1 and the back plate 11. The mark display device includes a meter mark display light cavity 9 and a meter mark display control board 10. The meter mark display light cavity is mounted on the meter mark display control board 10 through a light cavity fixing post 19.

[0054] The meter display light cavity 9 consists of two light cavities. The original two digital tubes are replaced with two light cavities to increase the size of the meter digital display and make the display clearer. Each of the two cavities is equipped with a light isolation grid 20. The light isolation grid 20 is used to isolate each LED.

[0055] The meter-marked light cavity 9 is a straight plate, with the side closest to the light diffusion plate being the digital display area. The distance numbers are displayed through the two light-transmitting windows in the lower part of the light diffusion plate 2 and the light-transmitting area of ​​the digital markings on the front cover plate 1.

[0056] The meter display control board 10 is equipped with multiple LED beads, which are distributed in positions corresponding to the digital display area of ​​the meter display light cavity 9.

[0057] The meter display control board 10 is provided with a light cavity mounting hole 18; the light cavity fixing post 19 of the meter display light cavity 9 is inserted into the light cavity mounting hole 18 and fixed by heating with an electric soldering iron.

[0058] The meter mark display control board 10 is also provided with meter mark display control board mounting holes 13. The meter mark display control board fixing posts 14 on the back plate 11 are fixedly installed in the meter mark display control board mounting holes 13 to fix the meter mark display control board on the back plate and facilitate disassembly.

[0059] The meter display light cavity is mounted on the meter display control board 10 via the light cavity fixing post 19.

[0060] Furthermore, by programming the LED beads to turn them on and off via the meter display control board 10, flexible display of distance information can be achieved.

[0061] Specifically, the light cavity fixing post 19 on the meter display light cavity 9 is installed in the light cavity mounting hole 18 on the meter display control board 10, and then fixed by hot ironing. The meter display light cavity 9 is provided with a light isolation grid 20 to ensure that each lamp bead is isolated. The brightness of each lamp bead can be controlled by the meter display control board 10, thereby realizing the meter change and effectively ensuring that the light does not diffuse from other cavities, ensuring uniform digital brightness and no halo interference, and can still be clearly identified in smoke or complex lighting environments.

[0062] When displaying numbers, such as the number 8, which consists of 7 lines, the LEDs on each line are isolated by an optical isolation grid. The display control board can control the LEDs on and off of each line to output the desired number.

[0063] Furthermore, the sign display device is also equipped with wireless communication function, which can communicate remotely with an external remote control. The external remote control can randomly adjust the required distance value according to the actual situation on site and display it, without the need to customize corresponding digital signs for each distance, which facilitates the installation and operation of the staff.

[0064] like Figure 5 As shown, in this embodiment, the lower end of the back plate 11 is provided with a cable outlet hole for the power cord A section 4 to extend out. The power cord B section 6 is connected to the power cord A section 4 through the power cord connecting plate 5; the power cord connecting plate 5 is installed in the potting groove 15 through the connecting plate slot 17; the potting groove 15 is filled with waterproof potting compound.

[0065] Specifically, power cord A section 4 and power cord B section 6 are connected by power cord connecting plate 5. Then, power cord connecting plate 5 is installed in power cord connecting plate slot 17, and power cord B section 6 is installed in power cord B section fixing slot 16. Then, potting glue is added to the potting groove 15 for sealing, which treats the wire and completely seals the wire core gaps, fundamentally solving the problem of water entering the wire core. While ensuring the function of the lamp, it improves the protection reliability and display effect.

[0066] like Figure 1 As shown, in this embodiment, the upper end of the back plate 11 is provided with an integrated lamp bead control board 8, which is connected to the power line segment B 6.

[0067] The integrated LED control board 8 is a straight board, which is equipped with a controller and multiple light sources. The controller is used to control the on / off state of the light sources. The positions of the light sources correspond to the positions of the two arrow-marked light-transmitting areas, and they are evenly distributed on the straight board. By controlling the on / off state of the light sources through the controller, the arrow marks can be displayed evenly and effectively, achieving accurate guidance of evacuation direction.

[0068] Furthermore, the integrated LED control board 8 can be installed using a slot structure. The back plate 11 has a slot that matches the shape of the integrated LED control board 8. The integrated LED control board 8 is fixedly attached to the upper end of the back plate 11 through the slot, which facilitates disassembly and maintenance.

[0069] like Figure 1 As shown, in this embodiment, the waterproof sign light also includes a light isolation plate 7, which abuts against the light diffusion plate 2 and the back plate 11 respectively. The light isolation plate 7 is used to isolate the multiple light sources in the integrated lamp control board 8 into two parts, which correspond to the positions of the two arrow-marked light-transmitting areas respectively.

[0070] In the event of a fire, the controller controls the light source, illuminating the light-transmitting area of ​​the arrow markings indicating the escape direction, while turning off the arrow in the other direction. The light is isolated by a light isolation plate, ensuring that the light from the left and right arrow markings does not interfere with each other, making the display clearer and allowing people to choose the evacuation direction more quickly and accurately.

[0071] Furthermore, the optical isolation plate 7 can be installed using a slot structure. The back plate 11 has a slot that matches the shape of the optical isolation plate 7. The optical isolation plate 7 is fixedly attached to the upper end of the back plate 11 through the slot, which facilitates disassembly and maintenance.

[0072] like Figure 1 As shown, the front cover plate 1 is provided with multiple fixing studs, and the light diffusion plate 2, the back plate 11 and the sealing gasket 3 are respectively provided with mounting holes that match the fixing studs. The front cover plate 1, the light diffusion plate 2, the sealing gasket 3 and the back plate 11 are sequentially fixed and connected by screws 12 and fixing studs, so that the front cover plate, the light diffusion plate, the sealing gasket and the back plate are firmly fixed together, which improves the stability of the sign light structure, forms an integrated structure, makes the interior completely sealed, initially avoids dust and water ingress, and improves the overall performance and service life of the lamp.

[0073] In this embodiment, firstly, the light cavity fixing post 19 on the meter mark display light cavity 9 is installed in the light cavity mounting hole 18 on the meter mark display control board 10, and then fixed by hot ironing, that is, the mark display device is fixedly assembled.

[0074] Then, the power cord connection plate slot 17 is soldered into the potting groove 15, and the power cord connection plate 5 is installed in the power cord connection plate slot 17. The power cord connection plate 5 connects power cord section A 4 and power cord section B 6. Potting glue is added into the potting groove 15 for sealing. That is, the wire potting structure is fixed and assembled.

[0075] Secondly, install the integrated control board 8 for the LED beads, the light isolation board 7, and the sign display device at the corresponding positions on the back panel 11.

[0076] Secure the front cover 1, light diffuser 2, sealing gasket 3, and back plate 11 sequentially using screws 12 and fixing studs to complete the installation of the entire light fixture. Connect the power supply via section A of the power cord. The adjustable waterproof marker light will then begin operation.

[0077] Furthermore, the front cover plate 1 has a sign light fixing hole, and the sign light fixture is fixed to the wall using bolts.

[0078] In this embodiment, the designed adjustable meter-marker waterproof marker light with encapsulated conductors can dynamically display distance information, making it suitable for tunnels and utility tunnels where distance information needs frequent updates. Its independent and detachable structural design makes it suitable for rail transit and underground engineering projects where maintenance remains constant. The enlarged marker display device is suitable for public places with smoky environments or strong light interference. Simultaneously, the encapsulated conductor structure solves the problem of water ingress into the conductor core, improving waterproofing and the overall performance of the light fixture.

[0079] The waterproof sign light in this embodiment can significantly improve waterproofness, visibility, maintainability and environmental adaptability while maintaining the basic functions of traditional lighting fixtures, making it particularly suitable for various emergency evacuation sites with high requirements for safety and reliability.

[0080] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
