Description
Technical Field
[0001] The utility model relates to the technical field of highway sign lights, in particular to a tunnel escape arrow indicator light. Background Art
[0002] Emergency evacuation sign lights are installed in tunnels and underground pedestrian passages, such as those on railways, highways, and subways, to indicate evacuation directions and distances in the event of an emergency. Typically, these lights indicate the exits leading to two different evacuation directions and the distances to those exits. In special circumstances, blocked exits may also need to be marked to prevent evacuees or vehicles from heading in the wrong direction.
[0003] In the prior art, a common emergency evacuation sign light is a flat-panel light box mounted on the sidewall of a tunnel. Two areas on the light box display evacuation signs for two different directions, respectively. For example, patent publication number CN208139003U discloses a tunnel-specific evacuation sign light. The light consists of a front cover and a rear cover. The front cover is integrally formed with a frame and two inclined cover plates covering the frame. The cover plates are equipped with indicator markings. A waterproof rubber seal is installed between the front and rear covers. The rear cover features a cylindrical protrusion with a screw hole. A dedicated mounting bracket with a U-shaped step is used. The U-shaped step has a first retaining groove for retaining the screws at the rear cover's inlet port and a second retaining groove for retaining the cylindrical protrusion. A spring latch is installed at the second retaining groove. The spring latch has a circular hole that fits over the cylindrical protrusion and a locking protrusion. A locking groove is located next to the second retaining groove. This utility model offers a reasonable indication angle, avoiding blind spots. It uses a dedicated mounting bracket that snaps into place and secures the installation, making installation and removal simple and convenient. However, the prior art solution disclosed in this utility model has the following problems:
[0004] 1. Lack of backup power supply for emergency backup;
[0005] 2. While having a wide indication angle, there is no restriction on the light source, resulting in the light received by the direct light of the lamp being more dazzling. Utility Model Content
[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to:
[0007] 1. Provide a tunnel escape arrow indicator light with a backup power supply so that it can be used normally during power outages and can be replaced according to the aging of the backup power supply during inspections.
[0008] Second, provide a tunnel escape arrow indicator light, which can keep it on and allow observers to receive a bright light reminder at a specific angle and distance.
[0009] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a tunnel escape arrow indicator light, comprising a substrate and a plurality of indicator lights, wherein a detachable battery compartment is provided on the substrate, the battery compartment is electrically connected to the indicator lights, and the plurality of indicator lights are arranged in an arrow shape on one side of the substrate.
[0010] The battery compartment in this solution is located on the side of the baseboard. It houses an external power port and an internal power port. The external power port corresponds to the backup battery, while the internal power port is connected to the indicator light or the circuit board that controls it. The baseboard should also provide space for the regular power supply circuit to enter and exit, allowing it to connect to the indicator light or the circuit board that controls it.
[0011] Optionally, a grid plate is provided on the substrate, and the position of the grid plate corresponds to the position of the indicator light.
[0012] The grille plate covers the indicator light and plays a certain anti-glare function.
[0013] Optionally, a light-transmitting area is provided on the grille plate, and the light-transmitting area corresponds to the position of the indicator light. At least a first gap, a second gap and a third gap are provided in the light-transmitting area, and both side walls of the first gap, the second gap and the third gap are parallel to each other; the angles of the side walls of the first gap, the second gap and the third gap relative to the light-emitting surface of the indicator light decrease successively.
[0014] This solution uses a first gap, a second gap, and a third gap with sequentially changing light transmission angles, and can be observed by observers at three different distances.
[0015] Preferably, the patterns formed by the first gaps, the patterns formed by the second gaps, and the patterns formed by the third gaps are all different, and can display escape arrows or escape data of different shapes to observers at different distances under poor visibility conditions.
[0016] Optionally, the first gap, the second gap and the third gap are arranged in sequence in the light-transmitting area, the number of the first gap, the second gap and the third gap corresponds one to one, and there are several first gaps, the second gap and the third gap.
[0017] Optionally, one of the two side walls of the first, second, and third gaps may be a smooth mirror surface that fully reflects the light from the indicator light, while the other side wall may be a rough surface that diffusely reflects the light from the indicator light. Designers may adjust the light reflectivity of the two side walls based on the application scenario.
[0018] Optionally, the substrate is rectangular on a side close to the indicator light, and mounting plates are extended from both the upper and lower ends of the substrate, and a plurality of mounting holes are provided on the mounting plates.
[0019] Optionally, there are at least seven indicator lights.
[0020] The beneficial technical effects of the present invention are as follows: through the detachable battery compartment provided on the side of the base plate, the device can be used normally during a power outage, and can also be replaced according to the aging of the backup power supply during inspections; through the specially designed grille plate, a flashing prompt effect is given to observers who are gradually approaching.

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.
[0025] Reference Figure 1-2 As shown, a tunnel escape arrow indicator light 2 includes a base plate 1 and indicator lights 2. The base plate 1 is provided with a removable battery compartment 3, which is electrically connected to the indicator lights 2. Nine indicator lights 2 are arranged in an arrow shape on one side of the base plate 1. The side of the base plate 1 near the indicator lights 2 is rectangular. Mounting plates 4 extend from both the upper and lower ends of the base plate 1, and the mounting plates 4 are provided with a plurality of mounting holes 5.
[0026] A grid plate 9 is provided on the base plate 1, and its position corresponds to that of the indicator light 2. A light-transmitting area is provided on the grid plate 9, corresponding to the position of the indicator light 2. The light-transmitting area includes at least a first gap 6, a second gap 7, and a third gap 8. The sidewalls of the first gap 6, the second gap 7, and the third gap 8 are parallel to each other; the angles of the sidewalls of the first gap 6, the second gap 7, and the third gap 8 relative to the light-emitting surface of the indicator light 2 decrease in sequence. The first gap 6, the second gap 7, and the third gap 8 are arranged sequentially in the light-transmitting area, and the number of the first gap 6, the second gap 7, and the third gap 8 corresponds to one another, with multiple first gaps 6, the second gap 7, and the third gap 8 each existing.
[0027] The battery compartment 3 of this solution is located on the side of the base plate 1. It contains an external power interface and an internal power interface. The external power interface corresponds to the backup battery, and the internal power interface is connected to the indicator light 2 or the circuit board that controls the indicator light 2. The base plate 1 should also leave space for the regular power line to enter and exit, so that the regular power line can be connected to the indicator light 2 or the circuit board that controls the indicator light 2.
[0028] The grid plate 9 covers the indicator light 2 and plays a certain anti-glare function. This solution adopts the first gap 6, the second gap 7 and the third gap 8 with sequentially changing light transmission angles, which can be observed by observers at three different distances.
[0029] Figure 2 The lines with small arrows represent light, while the lines with large arrows represent the observer's movement trajectory. At the emergency evacuation site, an observer moving from far to near toward indicator light 2 would sequentially observe reflected light from the sidewalls of third gap 8, reflected light from the sidewalls of second gap 7, direct light from indicator light 2 through first gap 6, direct light from indicator light 2 through second gap 7, and direct light from indicator light 2 through third gap 8. This design enhances the power of indicator light 2 for a better indication effect without worrying about glare caused by overly strong light.
