[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 4 As shown, it is a multifunctional emergency indicator light 10 according to an embodiment of the present invention, comprising a supporting frame 100, a first light guide plate 310, a second light guide plate 320, a top light plate 200, a first indicator light 210 and a second indicator light 220;

[0035] The support frame 100 is provided with an installation cavity 101, the ceiling light board 200 is provided at a first end of the installation cavity 101, the first indicator light 210 and the second indicator light 220 are provided on the ceiling light board 200, and the first indicator light 210 and the second indicator light 220 emit light toward a second end of the installation cavity 101;

[0036] The first light guide plate 310 and the second light guide plate 320 are disposed in the mounting cavity 101, and the first light guide plate 310 and the second light guide plate 320 are disposed parallel to each other, an end surface of a first end of the first light guide plate 310 faces the first indicator light 210 and is aligned with the first indicator light 210, and an end surface of a first end of the second light guide plate 320 faces the second indicator light 220 and is aligned with the second indicator light 220;

[0037] A light guide portion 321 is provided on a protruding surface of the second light guide plate 320 facing the first light guide plate 310;

[0038] The first indicator light 210 is configured to light up after power is supplied;

[0039] The second indicator light 220 is configured to light up when a trigger signal is present.

[0040] In this embodiment, the support frame 100 is used to support the first light guide plate 310, the second light guide plate 320 and the top light plate 200. The first light guide plate 310 is provided with an indicator mark, which can be formed by silk screen printing or ink coating. The indicator mark carries the indication information, for example, the indication information is the direction information of the escape exit. In this embodiment, the end faces other than the end face of the first end of the first light guide plate 310 are provided with a reflective layer, so that the light incident from the end face of the first end of the first light guide plate 310 will propagate along the first light guide plate 310 to the other end faces, and be reflected by the reflective layer located at the other end faces. The reflective layer reflects the light to the middle part of the first light guide plate 310, and the light is scattered and diffused to the outside by the middle part of the first light guide plate 310, so that the indicator mark located in the middle part of the first light guide plate 310 can be illuminated by the light, so as to be highlighted.

[0041] In this embodiment, the first light guide plate 310 and the second light guide plate 320 are both made of transparent materials, so that the first light guide plate 310 and the second light guide plate 320 can transmit and guide light. In one embodiment, the material of the first light guide plate 310 is glass, in one embodiment, the material of the first light guide plate 310 is acrylic, and in one embodiment, the material of the first light guide plate 310 is PE (Polyethylene) or PC (polycarbonate).

[0042] It is worth mentioning that the light guide portion 321 protruding from the surface of the second light guide plate 320 can guide light, so that the light can diffuse from both sides of the light guide portion 321 to form a luminous effect. Specifically, the side of the second light guide plate 320 facing the first light guide plate 310 is the output surface, and the light guide portion 321 is protruding from the second light guide plate 320 along a first direction, wherein the first direction is perpendicular to the output surface, and a diffusion layer is formed on the side of the light guide portion 321 in the second direction, and the second direction is perpendicular to the first direction, for example, the diffusion layer is a frosted layer, for example, the diffusion layer includes a plurality of uneven diffusion stripes, so that when light propagates along the inside of the second light guide plate 320 to the light guide portion 321, it can diffuse from the side of the light guide portion 321, and the diffusion layer on the side of the light guide portion 321 diffuses the light, thereby forming a luminous effect of the light guide portion 321.

[0043] In this embodiment, the end faces of the second light guide plate 320 other than the end face of the first end are provided with a reflective layer, and the reflective layer can reflect the light incident along the first end of the second light guide plate 320 to the light guide portion 321 in the middle of the second light guide plate 320, and the light is reflected and scattered to the outside by the light guide portion 321 provided with a protrusion, so that the light guide portion 321 on the second light guide plate 320 produces a luminous effect. For example, the shape of the light guide portion 321 is X-shaped. For example, the light guide portion 321 is arrow-shaped. For example, the shape of the light guide portion 321 is text, for example, the word EXIT, for example, the word exit and an arrow pattern.

[0044] In one embodiment, the light color of the first indicator light 210 is different from the light color of the second indicator light 220. In this embodiment, in daily work, the light emitted by the first indicator light 210 causes the first light guide plate 310 to generate light of one color, and when there is an emergency, the light emitted by the second indicator light 220 causes the light guide portion 321 of the second light guide plate 320 to emit light of a second color, which is different from the daily state, thereby playing a more obvious warning and alarm role.

[0045] In one embodiment, the light color of the second indicator light 220 is red, and the light color of the first indicator light 210 is white. In this embodiment, under normal conditions, the light emitted by the first indicator light 210 causes the first light guide plate 310 to emit white light, and when there is an emergency, the light emitted by the second indicator light 220 causes the light guide portion 321 of the second light guide plate 320 to emit red light, thereby providing a more obvious warning and alarm effect.

[0046] The ceiling light panel 200 is used to support the first indicator light 210 and the second indicator light 220, and to supply power to the first indicator light 210 and the second indicator light 220, wherein a first circuit and a second circuit are provided on the ceiling light panel 200, the first circuit is electrically connected to the first indicator light 210, and the second circuit is electrically connected to the second indicator light 220, so that the ceiling light panel 200 can independently supply power to the first indicator light 210 and the second indicator light 220, respectively. In daily work, the first indicator light 210 is turned on, and the light is transmitted to the first light guide plate 310, so that the first light guide plate 310 is illuminated. The first light guide plate 310 is illuminated, and can highlight the indication mark (indication information); when an emergency event occurs, the second indicator light 220 is triggered to light up, and the second indicator light 220 emits light of a different color from the first indicator light 210, thereby serving to highlight the warning.

[0047] In some embodiments, the light guide portion 321 is a light guide bar that is protruded from the second duct plate on one side facing the first light guide plate 310. For example, the light guide bar is X-shaped, for example, the light guide bar is in the shape of text, for example, the light guide bar is in the shape of an arrow. In this embodiment, the light guide portion 321 is set as an integral and continuous light guide bar, which can make the light emission present an overall form, which is conducive to improving recognition.

[0048] In one embodiment, Figure 2 and Figure 3 As shown, the light guide portion 321 includes a plurality of protrusions 322 protruding from the surface of the second light guide plate 320 and arranged in an array.

[0049] In this embodiment, the protrusions 322 are arranged in an array to form a light guide portion 321. For example, the protrusions 322 are arranged in an X shape, for example, the protrusions 322 are arranged in an array in a text shape, for example, the protrusions 322 are arranged in an arrow shape.

[0050] It is worth mentioning that, since the second light guide plate 320 is arranged adjacent to the first light guide plate 310, the area of ​​the light guide portion 321 is too large, and it is easy to reflect light to the first light guide plate 310 over a large area, so that the display of the indicator on the first light guide plate 310 is interfered by the light of the second indicator light 220. In order to avoid this situation, in this embodiment, the light guide portion 321 is set as a dot matrix convex point 322, each convex point 322 is set as a circle, and the diameter of the convex point 322 is 3mm to 5mm, and a diffusion layer is set on the side of the convex point 322 in the second direction, so that the light can be diffused from the second direction along the diffusion layer, and a large area of ​​reflection to the first light guide plate 310 is avoided, so that the dot matrix convex point 322 on the second light guide plate 320 and the indication information on the first light guide plate 310 can be displayed separately and independently. In this embodiment, the convex point 322 can be formed on the surface of the second light guide plate 320 by laser cutting, and can also be formed on the surface of the second light guide plate 320 by mechanical grinding.

[0051] In one embodiment, if Figure 5 As shown, the indication mark on the first light guide plate 310 is an indication layer 311, which is attached to the first light guide plate 310. The indication layer 311 carries indication information, which is the direction information of the escape exit. The convex points 322 on the second light guide plate 320 are arranged in an array to form an X. The light emitted by the first indicator light 210 is white, and the light emitted by the second indicator light 220 is red. In this way, under normal circumstances, the white light emitted by the first indicator light 210 enables the image of the escape exit direction to be clearly displayed. When there is an emergency, the second indicator light 220 is turned on, so that the convex point 322 array on the second light guide plate 320 is turned on, thereby forming an X, which can play a role in highlighting.

[0052] In one embodiment, please combine Figure 1 and Figure 6 The emergency indicator light 10 also includes a control module 520 and a power supply module 510. The input end of the power supply module 510 is used to connect to the mains power, and the output end of the power supply module 510 is electrically connected to the control module 520 and the ceiling light panel 200 respectively. The control module 520 is electrically connected to the ceiling light panel 200. The control module 520 is used to control the first indicator light 210 to light up after power is turned on, and is also used to detect whether there is a trigger signal. When a trigger signal is detected, the second indicator light 220 is controlled to light up.

[0053] In this embodiment, the emergency indicator light 10 also includes a power supply box 500, in which a box cavity is provided, and a control module 520 and a power supply module 510 are both provided in the box cavity. The power supply module 510 includes a transformer, a rectifier, a filter, etc., and also includes a backup battery. The transformer is connected to the mains power supply and is used to convert the voltage of the mains power supply into a voltage suitable for powering the ceiling light board 200. The rectifier is used to convert AC power into DC power to power the control module 520 and the ceiling light board 200, and the backup battery is used to power each component after the mains power is cut off. By integrating the control module 520 and the power supply module 510 into the power supply box 500, the volume of the emergency indicator light 10 can be effectively controlled, and the power supply box 500 can play a supporting and fixing role. For example, the bottom of the power supply box 500 is connected to the support frame 100, and the power supply box 500 is fixed to the ceiling or wall by screws, or the power supply box 500 is hung on the wall or ceiling by a hanging chain.

[0054] The power box 500 is connected to the support frame 100, for example, the power box 500 is connected via screws, for example, the power box 500 is connected to the support frame 100 via a screw joint, one end of the screw joint is connected to the power supply module 510 in the power box 500 via a wire, and the other end of the screw joint is connected to the conductive sheet on the ceiling light panel 200. Through the screw joint, not only the fixed connection between the power box 500 and the support frame 100 can be achieved, but also the electrical connection between the power supply module 510 and the ceiling light panel 200 can be achieved.

[0055] It is worth mentioning that the trigger signal can be generated by an external smoke detector. For example, a smoke detector is provided externally, and the smoke detector is electrically connected to the control module 520. When the smoke detector detects smoke, a trigger signal is generated and sent to the control module 520. The control module 520 controls the second indicator light 220 to light up in response to the trigger signal. In some embodiments, a smoke detection module is provided in the power box 500, and the smoke detection module is electrically connected to the control module 520. The smoke detection module is used to detect smoke. When smoke is detected, a trigger signal is generated and sent to the control module 520.

[0056] In order to fix the first light guide plate 310 and the second light guide plate 320, in one embodiment, as shown in FIG. Figure 2 , Figure 4 and Figure 5As shown, the support frame 100 includes a first frame 110 and a second frame 120, the first frame 110 and the second frame 120 are connected, and a mounting cavity 101 is formed inside, a first frame opening 111 is arranged in the middle of the first frame 110, and a second frame opening 121 is arranged in the middle of the second frame 120, and light emitted by the first light guide plate 310 and the second light guide plate 320 is emitted to the outside through the first frame opening 111 and the second frame opening 121. It is worth mentioning that the connection between the first frame 110 and the second frame 120 can be connected by screws or by buckling.

[0057] In one embodiment, Figure 4 As shown, the first indicator light 210 includes a plurality of first lamp beads, each of which is equidistantly arranged along a first preset straight line, and the first preset straight line coincides with the central axis of the end surface of the first end of the first light guide plate 310 .

[0058] In the present embodiment, each first lamp bead is an LED (light-emitting diode) lamp bead. By arranging each first lamp bead along a first preset straight line, each first lamp bead can be accurately aligned with the end face of the first end of the first light guide plate 310, so that the light emitted by the first lamp bead can be accurately emitted to the first light guide plate 310 and reflected to the outside by the first light guide plate 310.

[0059] In one embodiment, Figure 4 As shown, the second indicator light 220 includes a plurality of second lamp beads, each of which is equidistantly arranged along a second preset straight line, and the second preset straight line coincides with the central axis of the end surface of the first end of the second light guide plate 320 .

[0060] In the present embodiment, each second lamp bead is an LED lamp bead, and by arranging each second lamp bead along a second preset straight line, each second lamp bead can be accurately aligned with the end face of the second end of the second light guide plate 320, so that the light emitted by the second lamp bead can be accurately emitted to the light guide portion 321 of the second light guide plate 320, and reflected to the outside by the light guide portion 321 of the second light guide plate 320.

[0061] It is worth mentioning that when light propagates in the first light guide plate 310 or the second light guide plate 320, it is easy to attenuate, resulting in weaker brightness at a position farther away from the first indicator light 210 or the second indicator light 220. In order to avoid the light attenuation problem caused by the light propagating in the first light guide plate 310 and the second light guide plate 320, in one embodiment, as Figure 2 and Figure 6As shown, the emergency indicator light 10 also includes a bottom light board 400, a third indicator light 410 and a fourth indicator light 420, the bottom light board 400 is arranged at the second end of the installation cavity 101, the third indicator light 410 and the fourth indicator light 420 are arranged on the bottom light board 400, and the third indicator light 410 and the fourth indicator light 420 emit light toward the first end of the installation cavity 101; the end face of the second end of the first light guide plate 310 faces the third indicator light 410 and is aligned with the third indicator light 410, the end face of the second end of the second light guide plate 320 faces the fourth indicator light 420 and is aligned with the fourth indicator light 420, the third indicator light 410 is configured to light up after power is turned on; the fourth indicator light 420 is configured to light up when a trigger signal is present.

[0062] In this embodiment, the bottom light board 400 is electrically connected to the power supply module 510, and the bottom light board 400 is used to power the third indicator light 410 and the fourth indicator light 420, wherein the light color of the third indicator light 410 is the same as the light color of the first indicator light 210, but the light emission direction is opposite, and the light emission color of the fourth indicator light 420 is the same as the light emission color of the second indicator light 220, but the light emission direction is opposite, so that the first indicator light 210 and the third indicator light 410 work at the same time, and the first indicator light 210 is incident from the first end of the first light guide plate 310 to the first In the light guide plate 310, the third indicator light 410 is incident from the second end of the first light guide plate 310 into the first light guide plate 310, the second indicator light 220 and the fourth indicator light 420 work simultaneously, the second indicator light 220 is incident from the first end of the second light guide plate 320 into the second light guide plate 320, and the fourth indicator light 420 is incident from the second end of the second light guide plate 320 into the second light guide plate 320. In this way, the incident light from two directions to the first light guide plate 310 and the second light guide plate 320 respectively can effectively compensate for the attenuation caused by the large propagation distance.

[0063] In one embodiment, the luminous color of the third indicator light 410 is different from the luminous color of the fourth indicator light 420. In this embodiment, in daily work, the light emitted by the third indicator light 410 causes the third light guide plate to produce light of one color. When there is an emergency, the light emitted by the fourth indicator light 420 causes the light guide portion 321 of the fourth light guide plate to emit light of a fourth color, thereby distinguishing it from the daily state, thereby playing a more obvious warning and alarm role. In one embodiment, the luminous color of the fourth indicator light 420 is red, and the luminous color of the third indicator light 410 is white. The fourth indicator light 420 and the second indicator light 220 are both red, which can effectively make the red light emitted by the light guide portion 321 more obvious.

[0064] In one embodiment, Figure 2 , Figure 4 and Figure 5 As shown, there are two second light guide plates 320, the two second light guide plates 320 are respectively arranged on both sides of the first light guide plate 310, the first light guide plate 310 is clamped between the two second light guide plates 320, and the two second light guide plates 320 have one side facing the first light guide plate 310 protruded with the light guide part 321.

[0065] In this embodiment, the first light guide plate 310 is located in the middle, and the second light guide plates 320 are respectively arranged on both sides of the first light guide plate 310. The two rows of second lamp beads on the top light plate 200 are respectively located on both sides of a row of first lamp beads. One side of the second light guide plate 320 facing the first light guide plate 310 is protruded and provided with the light guide part 321, and the other side of the second light guide plate 320 facing the first light guide plate 310 is protruded and provided with the light guide part 321. In this way, both sides of the light guide plate of the emergency knowledge lamp can emit light through the light guide part 321, and the red light emitted by the light guide part 321 can be seen in different directions. In addition, since the second light guide plate 320 is made of a transparent material, it can avoid blocking the indication layer 311 on the surface of the first light guide plate 310. In this way, when the second indicator light 220 is not illuminated, the first indicator light 210 and the light guide plate are illuminated, so that the indication layer 311 can be clearly displayed. When the second indicator light 220 is lit, the red dot matrix protrusions 322 glow to form an X, which can serve as a warning. Moreover, since the dot matrix protrusions 322 do not block the indication layer 311, the indication layer 311 can still be displayed, thereby making the indication effect better. In order to avoid the mixing of white light and red light, generally, the first indicator light 210 can be turned off when the second indicator light 220 is on, and the second indicator light 220 can be turned off when the first indicator light 210 is on. In one embodiment, the control module 520 is used to keep the second indicator light 220 and the fourth indicator light 420 off when the first indicator light 210 and the third indicator light 410 are on, and control the first indicator light 210 and the third indicator light 410 to be turned off when the second indicator light 220 and the fourth indicator light 420 are on. In this way, the mixing of white light and red light can be avoided.

[0066] However, although the above approach can avoid the mixing of white light and red light, in an emergency, if only the red light is turned on and the white light is turned off, the indication information will only rely on the red light and cannot be fully and clearly displayed. In order to avoid this problem, in an emergency, the white light and the red light can be selected to emit at the same time, but this will cause mixing. In order to avoid the mixing of red light and white light when white light and red light exist at the same time, and to avoid mixing of the first light guide plate 310 and the second light guide plate 320, in one embodiment, a first isolation layer is provided between the first end of the first light guide plate 310 and the first end of the second light guide plate 320, and a second isolation layer is provided between the second end of the first light guide plate 310 and the second end of the second light guide plate 320. In this embodiment, the first isolation layer and the second isolation layer are both opaque layers made of opaque materials. The first isolation layer and the second isolation layer may be coated on the first light guide plate 310, or on the second light guide plate 320, or may be separate sheets independent of the first light guide plate 310 and the second light guide plate 320. It is worth mentioning that when light enters the light guide plate, it will propagate along the light guide plate until it is emitted from the light guide plate. It is difficult for light to mix between the light guide plates. The main source of light mixing is on the end face of the light guide plate where the light is incident. Although the first indicator light 210 and the third indicator light 410 are aligned with the first light guide plate 310, and the second indicator light 220 and the fourth indicator light 420 are aligned with the second light guide plate 320, the light emitted by the first indicator light 210, the third indicator light 410, the second indicator light 220 and the fourth indicator light 420 are not straight lines, but diffuse at a certain angle. Therefore, part of the light from the first indicator light 210 and the third indicator light 410 will diffuse to the second light guide plate 320. Similarly, part of the light from the second indicator light 220 and the fourth indicator light 420 will diffuse to the first light guide plate 310. Therefore, in this embodiment, a first isolation layer and a second isolation layer are respectively arranged between the two ends of the first light guide plate 310 and the two ends of the second light guide plate 320, which can effectively prevent light from entering other light guide plates in the initial emission stage, thereby avoiding light mixing at the source.

[0067] In one embodiment, the material of the first isolation layer and / or the second isolation layer is a metal thin layer. In this embodiment, the metal thin layer is electrically connected to the control module 520 through a conductive circuit. The control module 520 is used to control the second indicator light 220 to light up and control the first isolation layer and / or the second isolation layer to be energized when a trigger signal is detected. In this embodiment, the metal thin layer is made of a metal material that expands after heating. When the second indicator light 220 is lit, the first isolation layer and the second isolation layer are heated and expanded after being energized. Since the thickness of the first isolation layer and the second isolation layer is only 0.03mm to 0.1mm, the thickness is extremely small, and the expansion in the thickness direction is not obvious, but the expansion in the width can make the first isolation layer and the second isolation layer extend in a direction parallel to the first light guide plate 310 and the second light guide plate 320, and then when the second indicator light 220 and the fourth indicator light 420 are lit, the first isolation layer and the second isolation layer can cover a larger area to avoid mixing of red light with the first light guide plate 310. In the normal state, the second indicator light 220 and the fourth indicator light 420 are off, the first indicator light 210 and the third indicator light 410 are working, the control module 520 controls the first isolation layer and the second isolation layer to be powered off, and when the first isolation layer and the second isolation layer cool down and shrink to their original width, since there is no emergency, only white light exists. Although a small part of the white light can be transmitted to the second light guide plate 320, it will not cause mixed light.

[0068] In one embodiment, the number of the first light guide plates is two, the two first light guide plates are respectively arranged on both sides of the second light guide plate, the second light guide plate is sandwiched between the two first light guide plates, and the two surfaces of the second light guide plates facing away from each other and facing the first light guide plates are respectively protruded with the light guiding parts.

[0069] In this embodiment, the second light guide plate is located in the middle, the first light guide plates are respectively arranged on both sides of the second light guide plate, the two rows of first lamp beads on the top light plate are respectively arranged on both sides of a row of second lamp beads, one side of the second light guide plate is convexly provided with the light guide part, and the other side is convexly provided with the light guide part, so that both sides of the second light guide plate can emit light through the light guide part, and the red light emitted by the light guide part can be seen in different directions. In addition, since the first light guide plate is made of transparent material, it can avoid blocking the light emitted by the second light plate. In this way, when the second indicator light does not emit light, the first indicator light and the light guide plate light up, so that the outermost indication layer can be clearly displayed, and when the second indicator light is on, the red dot matrix convex dots emit light to form an X, which can serve as a warning, and the red dot matrix can penetrate through the first light guide plate to the outside, forming a better indication effect.
