Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dynamic light, in particular to a dynamic light device, a lighting method and a vehicle. BACKGROUND

[0002] With the development of intelligent lamps, the requirements of automobile signal lights, decorative lights and atmosphere lights are increasing. Dynamic light effects are favored by vehicle manufacturers and end users. However, a large number of LEDs are required to achieve dynamic light effects, and more complex circuit hardware design and software design are required. The structure design and heat resistance control are also increasing, and the size and weight of the lamp are also increasing.

[0003] The prior art needs multiple LEDs (about 10-20mm per LED) to achieve the effect of dynamic light through a reflector or a thick-wall light guide to propagate light to a specified direction. The dynamic flow effect is achieved by controlling the on-off sequence of each LED through a chip.

[0004] Multiple LEDs (1 LED per 15-20mm) are required, which requires complex circuit design and chip control, resulting in high cost. Thick-wall parts are heavy, which also leads to an increase in cost. Neither thick-wall light guides nor reflectors can change shape, and they have poor versatility. Each project and each model needs to be re-molded. SUMMARY

[0005] In view of the defects in the prior art, the purpose of the present application is to provide a dynamic light device, a lighting method and a vehicle, which can solve the problem of complex circuit design and high chip control cost in the prior art for achieving dynamic light effects with multiple LEDs.

[0006] To achieve the above purpose, the technical scheme adopted by the present application is:

[0007] On the one hand, the present application provides a dynamic light device, characterized in that it comprises:

[0008] a light guide pipe;

[0009] a conveying device connected to both ends of the light guide pipe for outputting light guide liquid from the end into the light guide pipe;

[0010] a light emitting assembly connected to at least one end of the light guide pipe for emitting light to the light guide liquid flowing into the light guide pipe from the end, and making the light transmit out of the light guide pipe along with the flowing light guide liquid.

[0011] In some optional schemes, the conveying device comprises:

[0012] a liquid storage mechanism for storing light guide liquid;

[0013] A conveying mechanism is connected to the liquid storage mechanism. The conveying mechanism connects the liquid storage mechanism and the two ends of the optical guide tube, and is used to convey the light guiding liquid in the liquid storage mechanism from one end of the optical guide tube to the other end, and return it to the liquid storage mechanism.

[0014] In some alternative embodiments, the delivery mechanism includes a delivery pump, the input end of which is connected to the liquid storage mechanism, the output end of which is connected to one end of the light guide tube, and the other end of the light guide tube is connected to the liquid storage mechanism.

[0015] In some alternative solutions, the liquid storage mechanism includes two liquid storage tanks, one of which is connected to the input end of the delivery pump and an on / off valve is provided between the liquid storage tank and the delivery pump, and the other liquid storage tank is connected to the light guide tube and an on / off valve is provided between the liquid storage tank and the light guide tube. The light-emitting component includes two light-emitting elements, which are respectively disposed at both ends of the light guide tube.

[0016] In some alternative solutions, the delivery mechanism includes two delivery pumps, the input ends of which are connected to the liquid storage mechanism, and the output ends of which are respectively connected to both ends of the light guide tube. The light-emitting component includes two light-emitting elements, which are respectively disposed at both ends of the light guide tube.

[0017] In some alternative embodiments, the liquid storage mechanism includes two liquid storage tanks, which are respectively integrated with the two delivery pumps.

[0018] In some alternative solutions, the delivery pump and the liquid storage mechanism are connected by parallel liquid and gas connecting pipes, with the connection point between the liquid connecting pipe and the liquid storage mechanism located below the connection point between the gas connecting pipe and the liquid storage mechanism. Both the liquid connecting pipe and the gas connecting pipe are equipped with on / off valves.

[0019] In some alternative solutions, the ends of the light guide and the light-emitting component are provided with two branch pipes, which are respectively connected to the light-emitting component and the delivery device. The branch pipe connected to the light-emitting component is located below the branch pipe connected to the delivery device.

[0020] In some alternative designs, the light emitted by the light-emitting component is coaxial with the branch tube to which it is connected.

[0021] In some alternative solutions, the axis of the branch tube to which the light-emitting component is connected forms an angle greater than 90° with the axis of the main light-conducting circuit.

[0022] In some alternative solutions, a mounting bracket with a groove for mounting the light guide tube is also included.

[0023] In some alternative designs, the inner wall of the groove is provided with a reflective material.

[0024] On the other hand, the present invention provides a method for dynamically illuminating lights, characterized in that it is implemented using any of the dynamic lighting devices described above, and includes the following steps:

[0025] Upon receiving the command to turn on the light, the light-emitting component emits light into the light guide tube, and the light guide fluid is introduced into the light guide tube by the conveying device, so that the light passes through the light guide tube as the light flows forward with the light guide fluid.

[0026] In some alternative solutions, the light guiding fluid is transported from one end of the light guide tube to the other end, and then transported in the reverse direction from the light guide tube.

[0027] In some alternative solutions, air is intermittently supplied while the light-guiding fluid is being delivered into the light guide tube.

[0028] Thirdly, the present invention provides a vehicle including the dynamic lighting device described in any of the preceding claims.

[0029] Compared with existing technologies, the advantages of this invention are as follows: Upon receiving a light-lighting command, the light-emitting component emits light into the light guide tube, and a conveying device outputs light-guiding fluid into the light guide tube, allowing the light to pass through the fluid and travel forward with the fluid's flow. Furthermore, the light propagates within the light guide tube using the fluid as a medium. When it reaches the end of the fluid, it converges and reflects, forming a bright spot. This bright spot flows with the end of the fluid, while the remaining fluid portion is slightly dimmer than the bright spot at the end. The bright spot and the remaining light flow together within the light guide tube, creating a dynamic light effect, resembling a meteor trailing a tail. In this design, the light guide tube is a flexible, transparent material with a freely designable shape, offering high versatility. Moreover, the entire device only requires controlling the start and stop times of the conveying device and the light-emitting component, eliminating the need for complex circuit design and saving costs.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] like Figures 1-3 As shown, the present invention provides a dynamic lighting device, including: a light guide 1, a delivery device 2, and a light-emitting component 3.

[0042] The delivery device 2 is connected to both ends of the light guide tube 1 and is used to output the light guide liquid from the end into the light guide tube 1; the light-emitting component 3 is connected to at least one end of the light guide tube 1 and is used to emit light to the light guide liquid flowing into the light guide tube 1 from the end and to make the light pass through the light guide tube 1 as the light flows forward with the light guide liquid.

[0043] When using this dynamic lighting device, according to the received command to turn on the lights, the light-emitting component 3 emits light into the light guide tube 1, and the conveying device 2 outputs light-guiding fluid into the light guide tube 1, allowing the light to pass through the light guide fluid to the outside of the light guide tube 1 and move forward with the flow of the light guide fluid. Furthermore, the light propagates within the light guide tube 1 using the light guide fluid as a medium. When it reaches the end of the light guide fluid, it is focused and reflected to form a bright spot, such as... Figure 5As shown, the bright spot flows along the end of the light guide fluid, while the remaining portion of the light guide fluid is slightly dimmer than the bright spot at the end. The bright spot and the remaining portion of light flow together with the light guide fluid in the light guide tube 1, creating a dynamic light effect, resembling a meteor trailing a tail. In this design, the light guide tube 1 is a transparent tube made of flexible material, and its shape can be designed arbitrarily, making it highly versatile. Furthermore, the entire device only requires controlling the start and stop times of the delivery device 2 and the light-emitting component 3, eliminating the need for complex circuit design and saving costs.

[0044] like Figure 1 As shown, specifically, if a single-sided flowing light method is adopted, the light guiding liquid is input into the light guiding liquid from one end of the light guiding liquid using the conveying device 2 connected to both ends of the light guiding liquid 1, and the light-emitting component 3 is turned on to emit light into the light guiding liquid 1. The light-emitting component 3 and the input end of the light guiding liquid are located at the same end. The light-emitting component 3 emits light into the light guiding liquid 1, and the light guiding liquid is output into the light guiding liquid using the conveying device 2, so that the light passes through the light guiding liquid into the light guiding liquid 1 and moves forward with the flow of the light guiding liquid.

[0045] If the next flow lighting is required, turn off the light-emitting component 3, then use the conveying device 2 to deliver gas into the light guide tube 1, and let the light guide liquid in the light guide tube 1 flow out from the other end and back to the conveying device 2. Then use the conveying device 2 to input the light guide liquid into the light guide tube 1 from one end, and turn on the light-emitting component 3 to emit light into the light guide tube 1, so as to realize the next flow lighting.

[0046] If a bilateral flowing light method is adopted, a conveying device can be set at both ends of the light guide tube 1 to deliver light guiding fluid into the light guide tube 1. After the light guiding fluid is delivered and drained from one end, the light guiding fluid is then delivered from the other side. This cycle can achieve a bilateral flowing light pattern.

[0047] Single-sided flowing light refers to a lighting pattern where light can only flow from one end to the other, while double-sided flowing light refers to a lighting pattern where light can flow from one end to the other and also flow in the opposite direction.

[0048] In some optional embodiments, the delivery device 2 includes: a liquid storage mechanism and a delivery mechanism. The liquid storage mechanism is used to store the light guide liquid. The delivery mechanism is connected to the liquid storage mechanism and connects the two ends of the liquid storage mechanism and the light guide tube 1. The delivery mechanism is used to deliver the light guide liquid in the liquid storage mechanism from one end of the light guide tube 1 to the other end and return it to the liquid storage mechanism.

[0049] In this embodiment, when the lighting effect is not required, the light guide liquid is stored in the liquid storage mechanism. When the lighting effect is required, the light guide liquid in the liquid storage mechanism is transported from one end of the light guide tube 1 to the other end by the conveying mechanism and then flows back into the liquid storage mechanism. At the appropriate time when the conveying mechanism transports the light guide liquid in the liquid storage mechanism into the light guide tube 1, the light-emitting component 3 can be turned on to emit light, thereby achieving the effect of dynamic lighting.

[0050] In addition, in specific implementation, depending on the design requirements, a delivery mechanism can be set at both ends of the light guide tube 1, or a delivery mechanism can be set at only one end of the light guide tube 1, so as to achieve a single-sided flow mode or a double-sided flow mode; furthermore, depending on the design requirements of the space, one liquid storage mechanism or two liquid storage mechanisms can be selected to achieve the effect of flowing illumination.

[0051] like Figure 1 As shown, in some optional embodiments, the delivery mechanism includes a delivery pump 22, the input end of which is connected to the liquid storage mechanism, the output end of which is connected to one end of the light guide tube 1, and the other end of the light guide tube 1 is connected to the liquid storage mechanism.

[0052] In this embodiment, a delivery pump 22 inputs light-guiding liquid from the storage mechanism into one end of the light guide tube 1, and the light-emitting component 3 is turned on to emit light into the light guide tube 1. The light-emitting component 3 and the input end of the light guide liquid are located at the same end. The light-emitting component 3 emits light into the light guide tube 1, and the delivery device 2 outputs light-guiding liquid into the light guide tube 1. The light propagates in the light guide tube 1 using the light guide liquid as a medium, allowing the light to pass through the light guide liquid into the light guide tube 1 and move forward with the flow of the light guide liquid. When the light guide liquid fills the entire light guide tube 1 from the end connected to the delivery pump 22, the light guide liquid will flow back into the storage mechanism from the other end of the light guide tube 1.

[0053] If another round of continuous lighting is required, the light-emitting component 3 is turned off, and then gas is pumped into the light guide tube 1 using the delivery pump 22 to squeeze out all the light-guiding liquid in the light guide tube 1 and return it to the liquid storage mechanism. Then, the delivery pump 22 is used to input light-guiding liquid from the liquid storage mechanism into one end of the light guide tube 1, and the light-emitting component 3 is turned on to emit light into the light guide tube 1, thus achieving the next round of continuous lighting. This cycle can achieve a timed continuous lighting effect.

[0054] like Figure 2 As shown, in some optional embodiments, the liquid storage mechanism includes two liquid storage tanks 21, one of which is connected to the input end of the delivery pump 22 and an on / off valve is provided between the liquid storage tank 21 and the delivery pump 22, and the other liquid storage tank 21 is directly connected to the light guide tube 1 and an on / off valve is provided between the liquid storage tank 21 and the light guide tube 1. The light-emitting component 3 includes two light-emitting elements, which are respectively disposed at both ends of the light guide tube 1.

[0055] In this embodiment, a bilateral flowing light effect can be achieved. Specifically, the liquid storage tank 21 has a certain amount of empty space above it to be filled with gas, and both liquid storage tanks 21 are filled with a certain amount of light guiding liquid, which can fill the light guide tube 1.

[0056] Before starting the light, maintain a certain pressure in the storage tank 21 directly connected to the light guide tube 1. Open the on / off valve between the storage tank 21 and the delivery pump 22, and open the on / off valve between the light guide tube 1 and the storage tank 21. Use the delivery pump 22 to input the light guide liquid from the storage tank 21 to one end of the light guide tube 1, and turn on the light-emitting component 3 on the same side to emit light into the light guide tube 1. The light propagates in the light guide tube 1 with the light guide liquid as the medium, allowing the light to pass through the light guide liquid into the light guide tube 1. After the light guide liquid and gas fill the entire light guide tube 1, the light guide liquid will flow back from the other end of the light guide tube 1 into the storage tank 21.

[0057] When the light is intermittently lit in reverse, gas is supplied to the light guide tube 1 by the delivery pump 22, which squeezes out all the light guide liquid in the light guide tube 1 and flows back into the storage tank 21. Then, the on / off valve between the storage tank 21 and the delivery pump 22 is opened, and the on / off valve between the light guide tube 1 and the storage tank 21 is opened. The delivery pump 22 is closed, so that the light guide liquid is forced by the pressure in the storage tank 21 directly connected to the light guide tube 1 to the side connected to the delivery pump 22. The light-emitting component 3 on the same side is turned on to emit light into the light guide tube 1. The light propagates in the light guide tube 1 with the light guide liquid as the medium, so that the light passes through the light guide liquid into the light guide tube 1. After the light guide liquid and gas fill the entire light guide tube 1, the light guide liquid will flow back into the storage tank 21 from the other end of the light guide tube 1.

[0058] By repeating this process, a bidirectional flow lighting effect can be achieved using a design with one delivery pump 22 and two storage tanks 21. When the pressure in the storage tank 21 directly connected to the light guide 1 is insufficient, the delivery pump 22 can be used to extract the air above the storage tank 21, reducing the pressure in the storage tank 21 and facilitating the return of the light guide liquid in the other storage tank 21.

[0059] like Figure 3 As shown, in some optional embodiments, the delivery mechanism includes two delivery pumps 22, the input ends of which are connected to the liquid storage mechanism, and the output ends of which are respectively connected to both ends of the light guide tube 1. The light-emitting component 3 includes two light-emitting elements, which are respectively disposed at both ends of the light guide tube 1.

[0060] In this embodiment, two delivery pumps 22 are connected to both ends of the light guide 1, and light-emitting elements for emitting light into the light guide 1 are respectively provided at both ends of the light guide 1, which can realize a bidirectional dynamic lighting mode, as detailed below:

[0061] In the forward flow effect: the first pump 22 at the first end inputs light guiding liquid from the liquid storage mechanism into the first end of the light guide tube 1, and the light-emitting element at the first end is turned on to emit light into the light guide tube 1. The light propagates in the light guide tube 1 with the light guiding liquid as the medium, so that the light passes through the light guiding liquid into the light guide tube 1. The light will be focused at the end of the light guiding liquid and reflected to form a bright spot. The bright spot flows with the end of the light guiding liquid. The brightness of the remaining part of the light guiding liquid is slightly weaker than that of the bright spot at the end. The bright spot and the remaining part of the bright light flow together in the light guide tube 1 with the flow of the light guiding liquid.

[0062] When performing the reverse flow effect, after the light-guiding liquid flows from the first end of the light guide tube 1 to the second end and fills the entire light guide tube 1, the light-emitting element at the first end is turned off. Then, the gas is delivered into the light guide tube 1 by the delivery pump 22 at the first end, squeezing out all the light-guiding liquid in the light guide tube 1 and flowing back into the liquid storage mechanism from the second end of the light guide tube 1. The delivery pump 22 at the first end is then turned off. The light-guiding liquid is input into the light guide tube 1 from the liquid storage mechanism by the delivery pump 22 connected to the second end of the light guide tube 1, and the light-emitting element at the second end is turned on to emit light into the light guide tube 1. The light propagates in the light guide tube 1 with the light-guiding liquid as the medium, allowing the light to pass through the light guide liquid into the light guide tube 1. The light will be focused at the end of the light guide liquid and reflected to form a bright spot. The bright spot flows with the end of the light guide liquid. The remaining part of the light guide liquid is slightly weaker than the bright spot at the end. The bright spot and the remaining part of the light flow together in the light guide tube 1 with the flow of the light guide liquid.

[0063] like Figure 3 As shown, in some optional embodiments, the liquid storage mechanism includes two liquid storage tanks 21, which are integrated with two delivery pumps 22 respectively.

[0064] In this example, two liquid storage tanks 21 are integrated with two delivery pumps 22 respectively. When the light guide tube 1 is long, using a single liquid storage tank 21 would either require a very long connecting pipeline or require the liquid storage tank 21 to be designed to be very large so that the delivery pumps 22 on both sides can be connected to the liquid storage tank. In this solution, two liquid storage tanks 21 are integrated with two delivery pumps 22 respectively, which can save the space occupied by the entire device.

[0065] Of course, in other embodiments, when the light guide tube 1 is relatively short, a storage tank 21 can be used, and the delivery pumps 22 at both ends of the light guide tube 1 are connected to the storage tank 21, which can achieve the same effect. After the light guide liquid is delivered from the storage tank 21 to the light guide tube 1 by the delivery pump 22, it flows back into the storage tank 21. There will be no negative pressure, which can reduce the delivery load of the delivery pump 22 and improve the service life of the delivery pump 22.

[0066] In some optional embodiments, the delivery pump 22 is connected to the liquid storage mechanism through parallel liquid and gas connecting pipes, and the connection position of the liquid connecting pipe to the liquid storage mechanism is located below the connection position of the gas connecting pipe to the liquid storage mechanism. Both the liquid connecting pipe and the gas connecting pipe are equipped with on / off valves.

[0067] In this embodiment, when all the light-guiding fluid in the light guide tube 1 is drained, there is still some remaining space above the storage mechanism. For example, if only one storage tank 21 is used, there is still some remaining space above the storage tank 21 when all the light-guiding fluid in the light guide tube 1 is drained; if two storage tanks 21 are used, there is still some remaining space above both storage tanks 21 when all the light-guiding fluid in the light guide tube 1 is drained. In this example, when all the light-guiding fluid in the light guide tube 1 is drained, half of the remaining space is still left above the storage mechanism, and the stored light-guiding fluid can meet the light-guiding requirements of the device.

[0068] Both the liquid connecting pipe and the gas connecting pipe at the inlet end of the delivery pump 22 are connected to the liquid storage mechanism. In this example, they are connected to the liquid storage tank 21. The connection position between the liquid connecting pipe and the liquid storage tank 21 is such that when all the light guiding liquid in the light guide tube 1 is drained, the liquid storage tank 21 is below the liquid level of the light guiding liquid and can satisfy the requirement of extracting the light guiding liquid to fill the light guide tube 1. The connection position between the liquid connecting pipe and the liquid storage tank 21 is such that when all the light guiding liquid in the light guide tube 1 is drained, the liquid storage tank 21 is above the liquid level of the light guiding liquid.

[0069] In addition, on / off valves are installed on the liquid and gas connecting pipes.

[0070] This design allows for the intermittent lighting of light on the light guide tube 1, as detailed below:

[0071] When a design consisting of a delivery pump 22 and a storage tank 21 is adopted, the input end of the delivery pump 22 is connected to the storage tank 21 via parallel liquid and gas connecting pipes. The output end of the delivery pump 22 is connected to one end of the light guide 1, and the other end of the light guide 1 is connected to the storage tank 21. The end of the light guide 1 connected to the delivery pump 22 is connected to a light-emitting component 3. The end of the light guide 1 connected to the storage tank 21 can be directly connected to the storage tank 21, or it can be connected to the storage tank 21 using a connecting pipe.

[0072] Open the on / off valve on the liquid connecting pipe, and use the delivery pump 22 to input the light guiding liquid from the storage tank 21 to one end of the light guide tube 1. Turn on the light-emitting component 3 to emit light into the light guide tube 1. The light propagates in the light guide tube 1 with the light guiding liquid as the medium, allowing the light to pass through the light guiding liquid into the light guide tube 1. After traveling a certain distance with the flow of the light guiding liquid, close the on / off valve on the liquid connecting pipe and open the on / off valve on the gas connecting pipe to pump gas into the light guide tube 1. This can make the light in the light guide tube 1 intermittent. Repeat the process of opening and closing the on / off valves of the liquid connecting pipe and the gas connecting pipe until the light guiding liquid and gas fill the entire light guide tube 1. Then, the light guiding liquid will flow back from the other end of the light guide tube 1 into the storage tank 21. If another period of intermittent lighting is required, turn off the light-emitting component 3, close the on / off valve on the liquid connecting pipe, open the on / off valve on the gas connecting pipe, and then use the delivery pump 22 to deliver gas into the light guide tube 1, squeezing out all the light-guiding liquid in the light guide tube 1 and returning it to the storage tank 21. Then, use the delivery pump 22 again to input light-guiding liquid and gas from the storage tank 21 through the on / off valves on the liquid and gas connecting pipes into one end of the light guide tube 1, and turn on the light-emitting component 3 to emit light into the light guide tube 1, thus achieving the next intermittent period of intermittent lighting. This cycle can achieve the effect of intermittent periodic lighting.

[0073] like Figure 2 As shown, when bidirectional intermittent lighting is achieved using a design with one delivery pump 22 and two storage tanks 21, the delivery mechanism includes one delivery pump 22, and the storage mechanism includes two storage tanks 21. The input end of the delivery pump 22 is connected to one of the storage tanks 21, and the output end of the delivery pump 22 is connected to one end of the light guide 1. The other end of the light guide 1 is connected to the other storage tank 21. The input end of the delivery pump 22 is connected to the storage tank 21 through parallel liquid and gas connecting pipes. The end of the light guide 1 directly connected to the storage tank 21 is also connected through parallel liquid and gas connecting pipes. Light-emitting elements are connected to both ends of the light guide 1.

[0074] Before starting the light, maintain a certain pressure in the storage tank 21 directly connected to the light guide tube 1. Open the on / off valve on the liquid connecting pipe connected to the delivery pump 22, and simultaneously open the liquid or gas connecting pipe directly connected to the storage tank 21. Use the delivery pump 22 to input light guiding liquid from the storage tank 21 to one end of the light guide tube 1, and turn on the light-emitting component 3 on the same side to emit light into the light guide tube 1. The light propagates in the light guide tube 1 with the light guiding liquid as the medium, allowing the light to pass through the light guiding liquid and travel a certain distance with the flow of the light guiding liquid. Then, close the on / off valve on the liquid connecting pipe and open the on / off valve on the gas connecting pipe to pump gas into the light guide tube 1. This makes the light in the light guide tube 1 intermittent. Repeat this process of opening and closing the on / off valves of the liquid and gas connecting pipes until the light guiding liquid and gas fill the entire light guide tube 1. The light guiding liquid will then flow back from the other end of the light guide tube 1 into the storage tank 21.

[0075] When the reverse intermittent lighting is activated, the light-emitting component 3 on one side of the delivery pump 22 and the on / off valve on the liquid connecting pipe are closed, the on / off valve on the gas connecting pipe is opened, and then the delivery pump 22 is used to deliver gas into the light guide tube 1, squeezing out all the light guide liquid in the light guide tube 1 and flowing back into the liquid storage tank 21. Then, open the liquid and gas connecting pipes on the same side as the delivery pump 22; open the liquid connecting pipe directly connecting the light guide tube 1 to the storage tank 21, so that the light guide liquid is forced by the pressure in the storage tank 21 to the side connected to the delivery pump 22, and open the light-emitting component 3 on the same side to emit light into the light guide tube 1. The light propagates in the light guide tube 1 with the light guide liquid as the medium, so that the light passes through the light guide liquid into the light guide tube 1, and after traveling a certain distance with the flow of the light guide liquid, close the on / off valve on the liquid connecting pipe, open the on / off valve on the gas connecting pipe, and pump gas into the light guide tube 1. This can make the light intermittent in the light guide tube 1. In this way, the on / off valves of the liquid and gas connecting pipes directly connected to the light guide tube 1 are opened and closed in a cycle until the light guide liquid and gas fill the entire light guide tube 1. Then the light guide liquid will flow back from the other end of the light guide tube 1 into the storage tank 21.

[0076] By repeating this process, a bidirectional intermittent lighting effect can be achieved using a design with one delivery pump 22 and two storage tanks 21.

[0077] When the pressure in the liquid storage tank 21 directly connected to the light guide 1 is appropriate, the light can be turned on directly from one side of the liquid storage tank 21 directly connected to the light guide 1.

[0078] When intermittent lighting is not required, gas can be introduced into the light guide tube 1 without opening the air connection tube during the continuous lighting period. In addition, when the pressure in the liquid storage tank 21 directly connected to the light guide tube 1 is insufficient, the air above the liquid storage tank 21 can be extracted by the delivery pump 22 to reduce the pressure in the liquid storage tank 21 directly connected to the light guide tube 1.

[0079] like Figure 3 As shown, alternatively, two delivery pumps 22 and two storage tanks 21 can be used. The delivery pumps 22 and the corresponding storage tanks 21 are connected by parallel liquid and gas connecting pipes, and on / off valves are installed. By using the cooperation of the on / off valves and the delivery pumps 22, a bidirectional intermittent flow lighting effect can also be achieved. When achieving forward intermittent flow lighting, the delivery pumps 22 and the light-emitting element at the first end are turned on, and the on / off valves on the corresponding liquid and gas connecting pipes at the corresponding ends are controlled to open and close sequentially for a set time. That is, first, the on / off valve on the liquid connecting pipe is opened, and the on / off valve on the gas connecting pipe is closed for a set time. Then, the on / off valve on the gas connecting pipe is opened, and the on / off valve on the liquid connecting pipe is closed for a set time. This process is repeated until the light guide liquid fills the light guide tube 1. Then, the delivery pumps 22 at the first end discharge the light guide liquid in the light guide tube 1 to the storage tank 21 at the second end, thus achieving reverse intermittent flow lighting. To achieve the flowing light effect, when the light is flowing in a forward interval, the delivery pump 22 and the light-emitting element at the second end are turned on. The on / off valves on the liquid connecting pipe and the gas connecting pipe at the corresponding ends are controlled to open and close in sequence for a set time. That is, the on / off valve on the liquid connecting pipe is opened first, and the on / off valve on the gas connecting pipe is closed for a set time. Then the on / off valve on the gas connecting pipe is opened, and the on / off valve on the liquid connecting pipe is closed for a set time. This process is repeated until the light guiding liquid fills the light guiding tube 1. Then the delivery pump 22 at the second end is used to discharge the light guiding liquid in the light guiding tube 1 to the storage tank 21 at the first end.

[0080] In some optional embodiments, the ends of the light guide tube 1 and the light-emitting component 3 are provided with two branch tubes, which are respectively connected to the light-emitting component 3 and the delivery device 2. The branch tube connected to the light-emitting component 3 is located below the branch tube connected to the delivery device 2.

[0081] In this example, two branch pipes are connected to the light-emitting component 3 and the conveying device 2 respectively, and the branch pipe connected to the light-emitting component 3 is located below the branch pipe connected to the conveying device 2. This design ensures that the branch pipe connected to the light-emitting component 3 is always filled with light-guiding fluid, and the light emitted by the light-emitting component 3 directly enters the light-guiding fluid. This avoids the situation where there is gas in the branch pipe connected to the light-emitting component 3 when the conveying device is delivering the light-guiding fluid into the light guide tube 1. In this case, the light emitted by the light-emitting component 3 would have to pass through the gas before entering the main body of the light guide tube 1, resulting in a loss of light efficiency.

[0082] In some alternative embodiments, the light emitted by the light-emitting component 3 is coaxial with the branch tube to which it is connected.

[0083] In this embodiment, the light emitted by the light-emitting component 3 is coaxial with the branch pipe it is connected to. This design minimizes the loss of light efficiency. The refractive index of the light-guiding fluid is ≥1.32, which improves light efficiency.

[0084] like Figure 7As shown, in some optional embodiments, the angle α between the axis of the branch tube connected to the light-emitting component 3 and the axis of the main circuit of the light guide tube 1 is greater than 90°.

[0085] In this example, the angle between the axis of the branch pipe connected to the light-emitting component 3 and the axis of the main circuit of the light guide 1 is greater than 90° to prevent all the light emitted by the light-emitting component 3 from being reflected back. Generally, the angle between the axis of the branch pipe connected to the light-emitting component 3 and the axis of the main circuit of the light guide 1 should be as close to 180 degrees as possible to reduce light attenuation. Furthermore, the light-emitting component 3 uses an LED module and is positioned at a distance L ≥ 15mm from the end of the light guide. To ensure the design effect, the turning radius R of the light guide 1 is ≥ 5D (where D: the diameter of the light guide), thus avoiding loss of light efficiency.

[0086] like Figure 6 and Figure 4 As shown, in some optional embodiments, the dynamic lighting device further includes a mounting bracket 4 with a groove for mounting the light guide tube 1.

[0087] In this embodiment, placing the light guide 1 in the groove can reflect the light transmitted through the light guide 1, avoiding ineffective light loss. In this example, the shape of the groove is designed to match the shape of the light guide 1. Since the light guide 1 is circular, the groove is a semi-circular groove with a diameter matching the outer diameter of the light guide 1, which can better reflect the light transmitted through the light guide.

[0088] In some alternative embodiments, the inner sidewalls of the groove are provided with reflective material.

[0089] In some alternative embodiments, applying a reflective material to the inner wall of the groove can further reduce light loss and improve reflectivity. In this example, aluminum or high-gloss white is plated inside the groove of the light guide 1 support to enhance the brightness of the light guide.

[0090] In addition, in some optional embodiments, when the length of the light guide 1 is too long and the light efficiency loss is too great, resulting in poor lighting effect, a branch port can be added to the light guide 1 to increase the light-emitting element and thus achieve the effect of increasing brightness.

[0091] On the other hand, the present invention also provides a dynamic lighting method, which is implemented using the above-mentioned dynamic lighting device, and includes the following steps:

[0092] According to the received command to turn on the light, the light-emitting component 3 emits light into the light guide tube 1, and the light guide liquid is introduced into the light guide tube 1 by the conveying device 2, so that the light passes through the light guide tube 1 as the light flows forward with the light guide liquid.

[0093] Upon receiving the command to light up the lamp, the light-emitting component 3 emits light into the light guide tube 1, and the light-guiding liquid is fed into the light guide tube 1 via the conveying device 2. The light propagates within the light guide tube 1 using the light guide liquid as a medium. When it reaches the end of the light guide liquid, it converges and reflects the light, forming a bright spot. This bright spot flows with the end of the light guide liquid, while the remaining portion of the liquid is slightly dimmer than the bright spot at the end. The bright spot and the remaining light flow together with the light guide liquid within the light guide tube 1, creating a dynamic light effect, resembling a meteor trailing a tail. In this design, the light guide tube 1 is a flexible, transparent tube with a freely designable shape, offering high versatility. Furthermore, the entire device only requires controlling the start and stop times of the conveying device 2 and the light-emitting component 3, eliminating the need for complex circuit design and saving costs.

[0094] In some alternative embodiments, after the light guiding fluid is delivered from one end of the light guide tube 1 to the other end, the light guiding fluid is then delivered from the light guide tube 1 in the reverse direction.

[0095] In this embodiment, the light-guiding liquid is delivered in the forward direction and then in the reverse direction, thus achieving a bidirectional dynamic lighting effect.

[0096] The first device configuration uses one delivery pump 22, two storage tanks 21, and two light-emitting elements. One storage tank 21 is connected to the input end of the delivery pump 22, and an on / off valve is installed on the connecting pipe between the storage tank 21 and the delivery pump 22. The other storage tank 21 is directly connected to the light guide tube 1, and an on / off valve is installed on the connecting pipe between the storage tank 21 and the light guide tube 1. The two light-emitting elements are respectively installed at both ends of the light guide tube 1.

[0097] Both liquid storage tanks 21 have a certain amount of empty space above them to be filled with gas, and both liquid storage tanks 21 are filled with a certain amount of light guiding liquid, which can achieve the goal of filling the light guiding tube 1.

[0098] Before starting the light, maintain a certain pressure in the storage tank 21 directly connected to the light guide tube 1. Open the on / off valve between the storage tank 21 and the delivery pump 22, and open the on / off valve between the light guide tube 1 and the storage tank 21. Use the delivery pump 22 to input the light guide liquid from the storage tank 21 to one end of the light guide tube 1, and turn on the light-emitting component 3 on the same side to emit light into the light guide tube 1. The light propagates in the light guide tube 1 with the light guide liquid as the medium, allowing the light to pass through the light guide liquid into the light guide tube 1. After the light guide liquid and gas fill the entire light guide tube 1, the light guide liquid will flow back from the other end of the light guide tube 1 into the storage tank 21.

[0099] When the light is intermittently lit in reverse, gas is supplied to the light guide tube 1 by the delivery pump 22, which squeezes out all the light guide liquid in the light guide tube 1 and flows back into the storage tank 21. Then, the on / off valve between the storage tank 21 and the delivery pump 22 is opened, and the on / off valve between the light guide tube 1 and the storage tank 21 is opened. The delivery pump 22 is closed, so that the light guide liquid is forced by the pressure in the storage tank 21 directly connected to the light guide tube 1 to the side connected to the delivery pump 22. The light-emitting component 3 on the same side is turned on to emit light into the light guide tube 1. The light propagates in the light guide tube 1 with the light guide liquid as the medium, so that the light passes through the light guide liquid into the light guide tube 1. After the light guide liquid and gas fill the entire light guide tube 1, the light guide liquid will flow back into the storage tank 21 from the other end of the light guide tube 1.

[0100] By repeating this process, a bidirectional flow lighting effect can be achieved using a design with one delivery pump 22 and two storage tanks 21. When the pressure in the storage tank 21 directly connected to the light guide 1 is insufficient, the delivery pump 22 can be used to extract the air above the storage tank 21, reducing the pressure in the storage tank 21 and facilitating the return of the light guide liquid in the other storage tank 21.

[0101] The second device configuration uses two delivery pumps 22, two light-emitting elements, and one or two liquid storage tanks 21, i.e., a liquid storage mechanism. One liquid storage tank 21 is connected to the input end of the delivery pump 22, and an on / off valve is installed on the connecting pipe between the liquid storage tank 21 and the delivery pump 22. The other liquid storage tank 21 is directly connected to the light guide tube 1, and an on / off valve is installed on the connecting pipe between the liquid storage tank 21 and the light guide tube 1. The two light-emitting elements are respectively located at both ends of the light guide tube 1.

[0102] In the forward flow effect: the first pump 22 at the first end inputs light guiding liquid from the liquid storage mechanism into the first end of the light guide tube 1, and the light-emitting element at the first end is turned on to emit light into the light guide tube 1. The light propagates in the light guide tube 1 with the light guiding liquid as the medium, so that the light passes through the light guiding liquid to the outside of the light guide tube 1. The light will be focused at the end of the light guiding liquid and reflected to form a bright spot. The bright spot flows with the end of the light guiding liquid. The brightness of the remaining part of the light guiding liquid is slightly weaker than that of the bright spot at the end. The bright spot and the remaining part of the bright light flow together in the light guide tube 1 with the flow of the light guiding liquid.

[0103] When performing the reverse flow effect, after the light-guiding liquid flows from the first end of the light guide tube 1 to the second end and fills the entire light guide tube 1, the light-emitting element at the first end is turned off. Then, the gas is delivered into the light guide tube 1 by the delivery pump 22 at the first end, squeezing out all the light-guiding liquid in the light guide tube 1 and flowing back into the liquid storage mechanism from the second end of the light guide tube 1. The delivery pump 22 at the first end is then turned off. The light-guiding liquid is input into the light guide tube 1 from the liquid storage mechanism by the delivery pump 22 connected to the second end of the light guide tube 1, and the light-emitting element at the second end is turned on to emit light into the light guide tube 1. The light propagates in the light guide tube 1 with the light-guiding liquid as the medium, allowing the light to pass through the light guide liquid into the light guide tube 1. The light will be focused at the end of the light guide liquid and reflected to form a bright spot. The bright spot flows with the end of the light guide liquid. The remaining part of the light guide liquid is slightly weaker than the bright spot at the end. The bright spot and the remaining part of the light flow together in the light guide tube 1 with the flow of the light guide liquid.

[0104] In some alternative embodiments, air is intermittently supplied while the light-guiding fluid is being delivered into the light guide tube 1.

[0105] In this example, air is intermittently supplied while the light-guiding fluid is being delivered into the light guide tube 1. This includes both unidirectional and bidirectional intermittent light flow effects.

[0106] To achieve a unidirectional, intermittent flowing light effect, a design using a delivery pump 22 and a storage tank 21 is employed. The input end of the delivery pump 22 is connected to the storage tank 21 via parallel liquid and gas connecting pipes. The output end of the delivery pump 22 is connected to one end of the light guide tube 1, and the other end of the light guide tube 1 is connected to the storage tank 21. A light-emitting component 3 is connected to the end of the light guide tube 1 connected to the delivery pump 22. The end of the light guide tube 1 connected to the storage tank 21 can be directly connected to the storage tank 21, or the connecting pipes can be used to connect the light guide tube 1 to the storage tank 21.

[0107] Open the on / off valve on the liquid connecting pipe, and use the delivery pump 22 to input the light guiding liquid from the storage tank 21 to one end of the light guide tube 1. Turn on the light-emitting component 3 to emit light into the light guide tube 1. The light propagates in the light guide tube 1 with the light guiding liquid as the medium, allowing the light to pass through the light guiding liquid into the light guide tube 1. After traveling a certain distance with the flow of the light guiding liquid, close the on / off valve on the liquid connecting pipe and open the on / off valve on the gas connecting pipe to pump gas into the light guide tube 1. This can make the light in the light guide tube 1 intermittent. Repeat the process of opening and closing the on / off valves of the liquid connecting pipe and the gas connecting pipe until the light guiding liquid and gas fill the entire light guide tube 1. Then, the light guiding liquid will flow back from the other end of the light guide tube 1 into the storage tank 21. If another period of intermittent lighting is required, turn off the light-emitting component 3, close the on / off valve on the liquid connecting pipe, open the on / off valve on the gas connecting pipe, and then use the delivery pump 22 to deliver gas into the light guide tube 1, squeezing out all the light-guiding liquid in the light guide tube 1 and returning it to the storage tank 21. Then, use the delivery pump 22 again to input light-guiding liquid and gas from the storage tank 21 through the on / off valves on the liquid and gas connecting pipes into one end of the light guide tube 1, and turn on the light-emitting component 3 to emit light into the light guide tube 1, thus achieving the next intermittent period of intermittent lighting. This cycle can achieve the effect of intermittent periodic lighting.

[0108] To achieve a bidirectional, intermittent flowing light effect, a design can be used with one delivery pump 22 and two storage tanks 21, or two delivery pumps 22 and two storage tanks 21. The delivery pumps 22 and storage tanks 21 are connected via parallel liquid and gas connecting pipes, with on / off valves installed on both pipes. This configuration can also achieve a unidirectional, intermittent flowing light effect.

[0109] The following example illustrates a design using one transfer pump 22 and two storage tanks 21.

[0110] The input end of the delivery pump 22 is connected to one of the storage tanks 21, and the output end of the delivery pump 22 is connected to one end of the light guide tube 1. The other end of the light guide tube 1 is connected to the other storage tank 21. The input end of the delivery pump 22 is connected to the storage tank 21 through a parallel liquid connecting pipe and a gas connecting pipe. The end of the light guide tube 1 directly connected to the storage tank 21 is also connected through a parallel liquid connecting pipe and a gas connecting pipe. Light-emitting elements are connected to both ends of the light guide tube 1.

[0111] Before starting the light, maintain a certain pressure in the storage tank 21 directly connected to the light guide tube 1. Open the on / off valve on the liquid connecting pipe connected to the delivery pump 22, and simultaneously open the liquid connecting pipe and / or gas connecting pipe directly connected to the storage tank 21 of the light guide tube 1. Use the delivery pump 22 to input light guide liquid from the storage tank 21 to one end of the light guide tube 1, and turn on the light-emitting component 3 on the same side to emit light into the light guide tube 1. The light propagates in the light guide tube 1 with the light guide liquid as the medium, allowing the light to pass through the light guide liquid and travel a certain distance with the flow of the light guide liquid. Then, close the on / off valve on the liquid connecting pipe and open the on / off valve on the gas connecting pipe to pump gas into the light guide tube 1. This can make the light in the light guide tube 1 intermittent. Repeat the opening and closing of the on / off valves of the liquid connecting pipe and the gas connecting pipe until the light guide liquid and gas fill the entire light guide tube 1. The light guide liquid will then flow back from the other end of the light guide tube 1 into the storage tank 21.

[0112] When the reverse intermittent lighting is activated, the light-emitting component 3 on one side of the delivery pump 22 and the on / off valve on the liquid connecting pipe are closed, the on / off valve on the gas connecting pipe is opened, and then the delivery pump 22 is used to deliver gas into the light guide tube 1, squeezing out all the light guide liquid in the light guide tube 1 and flowing back into the liquid storage tank 21. Then, open the liquid and gas connecting pipes on the same side as the delivery pump 22; open the liquid connecting pipe directly connecting the light guide tube 1 to the storage tank 21, so that the light guide liquid is forced by the pressure in the storage tank 21 to the side connected to the delivery pump 22, and open the light-emitting component 3 on the same side to emit light into the light guide tube 1. The light propagates in the light guide tube 1 with the light guide liquid as the medium, so that the light passes through the light guide liquid into the light guide tube 1, and after traveling a certain distance with the flow of the light guide liquid, close the on / off valve on the liquid connecting pipe, open the on / off valve on the gas connecting pipe, and pump gas into the light guide tube 1. This can make the light intermittent in the light guide tube 1. In this way, the on / off valves of the liquid and gas connecting pipes directly connected to the light guide tube 1 are opened and closed in a cycle until the light guide liquid and gas fill the entire light guide tube 1. Then the light guide liquid will flow back from the other end of the light guide tube 1 into the storage tank 21.

[0113] By repeating this process, a bidirectional intermittent lighting effect can be achieved using a design with one delivery pump 22 and two storage tanks 21.

[0114] Thirdly, the present invention also provides a vehicle including the dynamic lighting device described in any of the preceding claims.

[0115] This dynamic lighting system is widely used in automotive interior ambient lighting and exterior signal lights.

[0116] In summary, this solution, based on the received command to light up the lamp, has the light-emitting component 3 emit light into the light guide tube 1, and the conveying device 2 output light-guiding fluid into the light guide tube 1, allowing the light to pass through the light guide fluid and travel forward with the flow of the fluid. The light propagates within the light guide tube 1 using the light guide fluid as a medium. When it reaches the end of the fluid, it is focused and reflected to form a bright spot. This bright spot flows with the end of the fluid, while the remaining portion of the fluid is slightly dimmer than the bright spot at the end. The bright spot and the remaining portion of the light flow together with the fluid within the light guide tube 1, creating a dynamic light effect, resembling a meteor trailing a tail. In this solution, the light guide tube 1 is a flexible, transparent tube with a freely designable shape, offering high versatility and reducing mold investment. Furthermore, the entire device only requires controlling the start and stop times of the conveying device 2 and the light-emitting component 3, eliminating the need for complex circuit design and saving costs. When the light weakens, only a few additional light inlets are needed to significantly increase the brightness, saving 90% of the number of LEDs compared to traditional dynamic light effect solutions and reducing the weight by more than 40%.

[0117] Alternatively, a forward-flowing light effect can be achieved by using either one delivery pump 22, two storage tanks 21, and two light-emitting elements, or two delivery pumps 22, two storage tanks 21, and two light-emitting elements. Furthermore, in both of these designs, the input end of the delivery pump 22 is connected to the storage tank 21 via parallel liquid and gas connecting pipes, with on / off valves installed on these pipes. Through the control method described in the above specific embodiment, a bidirectional, intermittent flowing light effect can be achieved. Therefore, this solution can achieve rich flowing light effects through a simple structural layout and control logic.
