[0001] This application relates to the technical field of lighting equipment, and more specifically, to a lighting device and a lighting system. Background Technology

[0002] To meet users' needs for lifestyle and personalization, lighting equipment has developed rapidly. The LEDs in lighting equipment operate based on control information generated by the controller. When there are many LEDs in a lighting system, the timing of receiving control information varies significantly between different LEDs, resulting in large differences in the timing of their light changes and thus affecting the lighting effect.

[0003] Application content

[0004] In view of the above problems, this application proposes a lighting device and lighting system that can reduce the time difference in the receipt of control information by different LED beads, thereby reducing the time difference in the light changes of different LED beads and improving the user experience.

[0005] In a first aspect, this application provides a lighting device comprising: a main controller, multiple communication modules, and multiple lighting modules, wherein each communication module corresponds one-to-one with a lighting module, and each lighting module includes multiple LEDs. The multiple communication modules are connected sequentially, and the main controller is connected to the first communication module in the sequentially connected multiple communication modules. Each communication module is also connected to a corresponding lighting module. The main controller is used to generate control information to control the operating state of the lighting device and to send the control information to the first communication module. The multiple communication modules include a target communication module, which is used to determine target operating information in the control information and, if the target communication module is not the last communication module in the sequentially connected multiple communication modules, sends the control information to the next connected communication module. The target communication module can be any one of the multiple communication modules. The target lighting module is used to operate according to the target operating information and is the lighting module corresponding to the target communication module.

[0006] Secondly, this application also provides a lighting system; the lighting system includes: a mobile terminal and the aforementioned lighting device, wherein: the mobile terminal is used to generate control commands and send them to the lighting device; the lighting device is used to generate control information according to the control commands.

[0007] The technical solution provided in this application includes a lighting device comprising: a main controller, multiple communication modules, and multiple lighting modules. Each communication module corresponds one-to-one with a lighting module, and each lighting module includes multiple LEDs. The communication modules are connected sequentially, with the main controller connected to the first communication module in the sequential connection. Each communication module is also connected to its corresponding lighting module. The main controller generates control information to control the operating state of the lighting device and sends this control information to the first communication module. A target communication module determines the target operating information in the control information and, if the target communication module is not the last communication module in the sequential connection, sends the control information to the next connected communication module. The target communication module can be any one of the multiple communication modules. The multiple modules include the target communication module, and the target lighting module operates according to the target operating information. The target lighting module is the lighting module corresponding to the target communication module.

[0014] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be regarded as limitations on this application. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0015] To meet users' needs for lifestyle and personalization, lighting equipment has developed rapidly. In related technologies, control information generated by the controller to control the working state of the LEDs is transmitted sequentially among the LEDs in the lighting equipment; that is, the control information is transmitted from one LED to the next until it reaches the last LED. When there are many LEDs, the time difference between the LEDs connected to the front and the LEDs connected to the back receiving the control information can be large, resulting in significant differences in the timing of light changes and thus affecting the lighting effect.

[0016] In another related technology, multiple LEDs communicate directly with the controller, meaning the controller sends control information directly to the LEDs to control their operating status. When there are many LEDs, because each LED needs to communicate with the controller, the time difference between the different LEDs operating according to the control information is large, thus affecting the lighting effect.

[0017] In another related technology, the controller communicates directly with multiple relay boards, which in turn communicate with connected LEDs to control them to produce corresponding lighting effects. However, each relay board requires a microcontroller unit (MCU) to control it, which increases the cost of the device.

[0018] To address the aforementioned issues, this application provides a lighting device and a lighting system. The lighting device includes: a main controller, multiple communication modules, and multiple lighting modules, with each communication module corresponding to one of the lighting modules. Each lighting module includes multiple LEDs. The communication modules are connected sequentially, and the main controller is connected to the first communication module in the sequentially connected communication modules. Each communication module is also connected to its corresponding lighting module. The main controller generates control information to control the operating state of the lighting device and sends the control information to the first communication module. A target communication module determines the target operating information in the control information and, if the target communication module is not the last communication module in the sequentially connected communication modules, sends the control information to the next connected communication module. The target communication module can be any one of the multiple communication modules. A target lighting module operates according to the target operating information; the target lighting module is the lighting module corresponding to the target communication module.

[0019] Therefore, multiple communication modules communicate directly with the main controller to determine the target working information, and the lighting equipment communicates directly with the corresponding communication module to present the corresponding lighting effect according to the target working information, effectively reducing the time difference between different lamp beads receiving the target working information.

[0020] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0021] Example 1

[0022] Please refer to Figure 1, which is a schematic diagram of the structure of a lighting device provided in an embodiment of this application. As shown in Figure 1, the lighting device 100 in Figure 1 includes a main controller 110, multiple communication modules 120, and multiple lighting modules 130.

[0023] In this configuration, multiple communication modules 120 correspond one-to-one with multiple lighting modules 130, and each lighting module 130 includes multiple LED beads 131. The multiple communication modules 120 are connected sequentially, and the main controller 110 is connected to the first communication module among the sequentially connected multiple communication modules 120. Each communication module 120 is also connected to its corresponding lighting module 130.

[0024] The main controller 110 is used to generate control information for controlling the working status of the lighting equipment 130 and to send the control information to the first communication module.

[0025] The multiple communication modules 120 include a target communication module, which is used to determine the target working information in the control information and, if the target communication module is not the last communication module in the multiple communication modules connected in sequence, sends the control information to the next connected communication module 120. The target communication module can be any one of the multiple communication modules 120.

[0026] The target lighting module is used to operate based on the target's working information. The target lighting module is the lighting module 130 corresponding to the target communication module.

[0027] The main controller 110 is a controller. In some embodiments, the user determines the lighting effect data (e.g., the brightness and color of the LEDs) of the lighting device according to actual needs. The main controller 110 generates control information based on the lighting effect data determined by the user.

[0028] In other embodiments, the main controller 110 pre-stores multiple lighting templates, which can be preset by the user. For example, a lighting template can make all LEDs 131 red. After the user selects a suitable lighting template according to the application scenario, the main controller 110 can generate control information based on the selected lighting template.

[0029] The control information may include multi-bit address information and lamp control status data (e.g., the operating parameters of the lamp 131). The main controller 110 transmits the generated control information to the first communication module 120, which in turn transmits the control information to the sequentially connected communication modules 120, so that all communication modules 120 can receive the control information.

[0030] When the communication module 120 receives the control information, it determines the target working information in the control information according to the corresponding address information, and then transmits the target working information to the connected lighting module 130. The lighting module 130 then determines the working parameters in the target working information according to the corresponding address information and performs the work to present the corresponding lighting effect.

[0031] Specifically, the communication module 120 can be an address forwarding chip. Each address forwarding chip has unique address information (e.g., address code). The address forwarding chip can compare and verify the address information with the address information contained in the control information. The address forwarding chip determines the data packet corresponding to the address information contained in the control information and its own address information as the target working information.

[0032] In other words, the target communication module is specifically used to extract information from the control information based on the address information corresponding to the target communication module, and obtain the target working information.

[0033] After the target communication module extracts the target operating information from the control information, it transmits the target operating information to the target lighting module connected to the target communication module. This means the target operating information is passed to the LEDs in the target lighting module. The LEDs in the target lighting module determine the target operating parameters based on the target operating information, and then operate according to these parameters (e.g., on / off state, color display, or brightness).

[0034] In the embodiments of this application, specifically, the LED 131 in the target lighting module is used to determine the corresponding address encoding information, and to determine the working parameters corresponding to the target working information based on the address encoding information, so as to determine the target working parameters.

[0035] Each LED 131 in the lighting module 130 has a unique address code. When the target communication module sends target operating information to the target lighting module, each LED 131 in the target lighting module compares and verifies its own address code with the address code in the target operating information. The data packet corresponding to the address code that matches the address code in the target operating information is determined as the target operating parameter. This allows the LED to operate according to the target operating parameter, resulting in the corresponding lighting effect (e.g., on / off, color display, or brightness).

[0036] In some embodiments, multiple LEDs can be connected in parallel. Since the LEDs are all connected in parallel, the communication module can simultaneously send target operating information to multiple LEDs. The multiple LEDs can jointly determine the corresponding address encoding information, and then determine the operating parameters corresponding to the target operating information based on the address encoding information. In turn, they can operate according to the operating parameters, which can reduce the time difference in information reception between LEDs, thereby reducing the time difference in light changes between different LEDs and improving the user experience.

[0037] In other embodiments, the multiple LEDs may include LEDs connected in parallel and in series. For example, the multiple LEDs may be three LEDs, where two LEDs are connected in series and then connected in parallel with the remaining LED.

[0038] Therefore, the control information generated by the main controller 110 is transmitted sequentially along the communication modules 120 connected in sequence. Multiple communication modules 120 extract the corresponding target working information from the control information in parallel, and send the target working information to the corresponding lighting module 130 so that the lighting module 130 presents the corresponding lighting effect according to the target working information.

[0039] In other words, the main controller 110 communicates directly with different communication modules 120, and the different communication modules 120 communicate directly with the corresponding LED beads 131, so that the lighting device 100 presents the corresponding lighting effect.

[0040] When the lighting device 100 contains a large number of LED beads 131, since different communication modules 120 extract the corresponding target working information from the control information in parallel, the time difference between different LED beads 131 receiving the target working information comes from the time difference between different communication modules 120 receiving the control information, thereby effectively reducing the time difference between different LED beads 131 receiving the target working information.

[0041] In some implementations, the main controller 110 is connected to the first communication module and to multiple communication modules 120 via a communication bus. The main controller 110 is connected to the communication modules 120 and to different communication modules 120 via a communication bus, which improves the transmission efficiency of control information between different communication modules 120 and further reduces the time difference in which different LEDs 131 receive the target working information.

[0042] In some embodiments, please refer to FIG2, which is a schematic diagram of another lighting device provided in an embodiment of this application. As shown in FIG2, the lighting device 100 further includes an adapter 140, which is connected to the main controller 110. The adapter 140 is used to provide power to the main controller 110.

[0043] The power supply provided by adapter 140 can be either 5V or 12V. It is understood that the operating voltage of the power supply can be flexibly adjusted according to the actual needs of the lighting equipment 100. This application does not limit the specific value of the operating voltage provided by the power supply.

[0044] When the operating voltage of the power supply is compatible with the operating voltage of the LED 131 (for example, the operating voltage of the power supply is 5V and the operating voltage of the LED 131 is 5V), the adapter 140 provides the required operating voltage to the LED 131 so that the LED 131 can work according to the target operating parameters in the target operating information determined by the target communication module 120.

[0045] In some implementations, when the operating voltage of the power supply is compatible with the operating voltage of the LED 131, and the power of the lighting module 130 is large (due to the large number of LEDs 131 and the brightness of the LEDs 131), the operating voltage provided by the power supply may not be able to ensure that the LEDs 131 can work normally.

[0046] For example, when there are many LED beads 131 and the operating voltage of the power supply is 5V, the voltage of the LED beads 131 connected to the subsequent communication module 120 will be much lower than 5V after the voltage drop, which will cause the brightness of the LED beads 131 at the end to weaken or not light up.

[0047] Based on the above issues, please continue to refer to Figure 2. In some embodiments, the lighting device 100 also includes multiple voltage conversion modules 150. The main controller 110 is connected to one end of the first voltage conversion module, and the other end of the first voltage conversion module is connected to the first communication module.

[0048] The two ends of the second voltage conversion module are respectively connected to two adjacent communication modules 120. The second voltage conversion module is any voltage conversion module 150 other than the first voltage conversion module among a plurality of voltage conversion modules 150. The two adjacent communication modules 120 connected to the second voltage conversion module are determined according to the power of the lamp bead.

[0049] The power of the LED is related to its brightness and the number of LEDs. The number of LEDs refers to the number of LEDs included in the lighting module 130.

[0050] The voltage conversion module 150 is used to convert the power supply voltage of the power supply to the operating voltage required by the lamp bead 131.

[0051] The voltage conversion module 150 can be a DC-DC converter circuit to convert the DC power supply into a DC voltage of the corresponding value to ensure that the operating voltage required by the LED 131 is provided.

[0052] The voltage conversion module 150 converts the operating voltage provided by the adapter 140 into the operating voltage required by the lamp 131, so as to avoid the lamp 131 failing to work properly due to excessively high or low operating voltage.

[0053]

Example 2

[0054] Please refer to Figure 3, which is a schematic diagram of another lighting device provided in this application embodiment. As shown in Figure 3, the difference between Embodiment 2 and Embodiment 1 is that the communication module 120 includes a communication LED 121, and the target communication module includes a target communication LED. Specifically, the lighting device 100 in Figure 3 includes a main controller 110 and a plurality of first modules 120a, each of the plurality of first modules 120a including a communication LED 121 and at least one lighting module 122.

[0055] Multiple first modules 120a are connected in sequence via communication LEDs 121, and the main controller 110 is connected to the communication LED 121 of the first first module among the multiple first modules 120a connected in sequence.

[0056] The main controller 110 can be used to generate control information to control the lighting status of multiple first modules 120a, and send the control information to the communication LED 121 in the first first module.

[0057] The target communication LED can be used to receive control information, determine target working information based on the control information, and send target working information to at least one target lighting module. If the target first module corresponding to the target communication LED is not the last first module 120a among a plurality of sequentially connected first modules 120a, control information is sent to the communication LED 121 in the next connected first module 120a.

[0058] Wherein, the target first module is any one of the multiple first modules 120a, the target communication lamp bead is the communication lamp bead 121 included in the target lighting module, and at least one target lighting module is at least one lighting module 122 included in the target lighting module.

[0059] The target lighting module can be used to determine the corresponding working parameters of the target lighting module based on the target working information, and to present the corresponding lighting effects based on the corresponding working parameters of the target lighting module.

[0060] The main controller 110 can be a control device. For example, the main controller 110 can be a CPU, etc.

[0061] The lighting status can be the brightness, color, and on / off state of the LED beads (communication LED bead 121 and lighting module 122).

[0062] The control information may include data packets corresponding to the lighting status of the LED beads. These data packets may include identification information and corresponding operating parameters. The identification information may include address information and encoding information. Each LED bead has unique address information and / or encoding information. Based on the LED bead's address or encoding information, the corresponding address or encoding information can be found in the data packet. Then, based on the corresponding address or encoding information in the data packet, the corresponding operating parameters are found, thus determining the operating parameters of a specific LED bead (communication LED bead 121 or lighting module 122). The LED bead then operates according to these operating parameters, thereby producing the corresponding lighting effect.

[0063] It is worth noting that each LED has unique identification information. Specifically, the communication LED 121 has unique address and encoding information, and the lighting module 122 has unique encoding information.

[0064] In some implementations, the user can independently determine the data corresponding to the lighting effect to be presented by the first module 120a (e.g., the brightness and color of each LED) according to actual needs, and send the data to the main controller 110. The main controller 110 then generates control information based on the data determined by the user. For example, if the user needs the first module 120a to display blue light to create a sky effect, the user can independently determine the data corresponding to making the first module 120a display blue light, and the main controller 110 then generates control information based on the data.

[0065] In other embodiments, the main controller 110 pre-stores multiple lighting templates, and generates control information based on the target lighting template. The lighting template can be a user-preset lighting state of all or some of the LEDs in the lighting device 100. Alternatively, the lighting template can be a pre-set lighting state of all or some of the LEDs in the lighting device 100 by the manufacturer according to the application scenario. For example, the lighting template could be that the first part of the LEDs in the lighting device 100 are off, while the second part are emitting yellow light to create a starry sky scene. The target lighting template can be any one of the multiple lighting templates.

[0066] In some implementations, the identity information includes the sequence information of the first module 120a (the connection order of the first module 120a relative to the main controller 110; for example, the sequence information of the first first module is 1, and the sequence information of the second first module connected to the first first module is 2). The control information includes multiple data information ordered in sequence, each of which corresponds to a first module 120a. The first module 120a determines the target operating information in the control information based on the sequence information.

[0067] For example, the control information includes data information A, data information B, and data information C ordered in sequence. The lighting device 100 includes a first module a, a first module b, and a first module c. Data information A corresponds to first module a, data information B corresponds to first module b, and data information C corresponds to first module c. When first module a receives control information, it determines the first data information A in the first segment as the target working information. When first module b receives control information, it determines the second data information B in the second segment as the target working information. This process continues until all first modules 120a determine the target working information.

[0068] The target operating information can be the data information corresponding to the lighting effect of the communication LED 121 and lighting module 122 included in a certain first module 120a. That is to say, the control information includes the data information corresponding to the lighting effect of the communication LED 121 and lighting module 122 included in all the first modules 120a of the entire lighting device 100, while the target operating information is the data information corresponding to the lighting effect of the communication LED 121 and lighting module 122 included in a certain first module 120a among all the first modules 120a of the lighting device 100.

[0069] Therefore, the main controller 110 generates control information according to actual needs and sends the control information to the communication LED 121. The communication LED 121 then transmits the control information to the communication LEDs 121 of other first modules 120a, and so on, so that the communication LEDs 121 in each first module 120a receive the control information, so that the communication LEDs 121 in each first module 120a determine the corresponding target working information from the control information, and then send the target working information to the connected lighting module 122, so that the communication LEDs 121 and the lighting module 122 determine the corresponding working parameters according to the target working information, and then present the corresponding lighting effect according to the corresponding working parameters.

[0070] To avoid communication between the main controller 110 and the communication LEDs 121 in each first module 120a, the memory burden of the main controller 110 is effectively reduced, and the time difference between different LEDs (communication LEDs 121 and lighting modules 122) in determining the working parameters is also effectively reduced, that is, the data processing time is shorter (the amount of target working information data is smaller).

[0071] The target communication LED can have an address forwarding function. Because of this function, the target communication LED can determine its target operating information from the control information based on its address information, and then send this target operating information to the lighting module connected to it. Specifically, the target communication LED can be used to extract information from the control information based on its address information to obtain the target operating information.

[0072] For example, after the communication LED 121 in the first module 120a receives the control information sent by the main controller 110, the communication LED 121 in the first module 120a extracts a segment of target working information corresponding to the address information from the control information based on its own address information, and then sends the control information to the communication LEDs 121 in other modules 120a connected to the communication LED 121 in the first module 120a. The communication LEDs 121 in other modules 120a then extract a segment of target working information corresponding to the identity information based on their own address information, and then send the control information to the communication LEDs 121 in other connected modules 120a, and so on, until all communication LEDs 121 in the first module 120a have received the control information. This avoids each communication LED 121 communicating with the main controller 110, which would cause a large memory burden on the main controller 110, and ensures that all communication LEDs 121 in the first module 120a receive the control information.

[0073] In some implementations, the target communication LED chip integrates an address forwarding chip to enable the target communication LED chip to have address forwarding functionality.

[0074] Furthermore, the target communication LED can also be used to extract the corresponding working parameters of the target communication LED from the target working information based on the encoding information of the target communication LED, and present the corresponding lighting effect based on the working parameters of the target communication LED.

[0075] In other words, after the target communication LED extracts the target working information corresponding to the address information of the target communication LED from the control information, the target communication LED then extracts the working parameters corresponding to the encoding information of the target communication LED from the target working information. The target communication LED then operates according to the working parameters corresponding to the encoding information of the target communication LED, so as to achieve the lighting effect corresponding to the working parameters.

[0076] In some embodiments, multiple first modules 120a are connected in series via included communication LEDs 121. For example, the main controller 110 is connected to the communication LED 121 included in the first first module, the communication LED 121 included in the first first module is connected in series with the communication LED 121 included in the second first module, the communication LED 121 included in the second first module is then connected in series with the communication LED 121 included in the third first module, and so on.

[0077] In some embodiments, multiple first modules 120a are connected in parallel sequentially via included communication LEDs 121. For example, the main controller 110 is connected to the communication LED 121 included in the first first module, and the communication LEDs 121 of the other first modules are all connected in parallel to the communication LEDs 121 included in the first first module.

[0078] The communication LED 121 determines the target operating information corresponding to itself in the received control information. Based on the target operating information, the communication LED 121 determines its own operating parameters and sends the target operating information to the lighting module 122 connected to it. The lighting module 122 connected to the communication LED 121 determines its corresponding operating parameters based on the target operating information and then transmits the target operating information to other lighting modules 122 connected to the communication LED 121. These other lighting modules 122 then determine their corresponding operating parameters based on the target operating information, thus enabling the LEDs (communication LED 121 and lighting modules 122) in the entire first module 120a to present corresponding lighting effects according to their respective operating parameters.

[0079] In some implementations, the communication LED 121 in each first module 120a is connected in parallel with at least one lighting module 122. For example, the communication LED 121 in the first module 120a is connected in parallel with all the lighting modules 122 in the first module 120a.

[0080] In some embodiments, the communication LED 121 in each first module 120a is connected in series with at least one lighting module 122. For example, the communication LED 121 in the first module 120a is connected in series with the first lighting module 122 in the first module 120a, and the other lighting modules 122 in the first module 120a are connected in series in sequence.

[0081] In some embodiments, the communication LED 121 in each first module 120a is connected in series with a portion of the lighting modules 122 in at least one lighting module 122. For example, the communication LED 121 in the first module 120a is connected in series with a portion of the lighting modules 122 in the first module 120a, and the communication LED 121 in the first module 120a is connected in parallel with other portions of the lighting modules 122 in the first module 120a.

[0082] In some embodiments, the communication LED 121 in each first module 120a is connected in parallel with a portion of the lighting modules 122 in at least one lighting module 122. The communication LED 121 in the first module 120a is connected in series with a portion of the lighting modules 122 in the first module 120a, and the communication LED 121 in the first module 120a is connected in parallel with other portions of the lighting modules 122 in the first module 120a.

[0083] After the target communication LED determines the target working information, it sends the target working information to the target lighting module connected to the target communication LED. The target lighting module then sends the target working information to other lighting modules 122 connected to the target lighting module, so that the lighting module 122 can determine the corresponding working parameters according to the target working information, and then present the lighting effect corresponding to the corresponding working parameters.

[0084] Specifically, the target lighting module can be used to determine the corresponding working parameters of the target lighting module from the target working information based on the coding information of the target lighting module, so as to present the corresponding lighting effect according to the working parameters of the target lighting module.

[0085] In other words, after the target communication LED sends the target working information to the target lighting module, the target lighting module determines the corresponding working parameters from the target working information based on the corresponding encoding information. After determining the corresponding working parameters, the target lighting module then sends the target working information to other lighting modules 122 connected to the target lighting module. The other lighting modules 122 then determine their corresponding working parameters from the target working information based on their corresponding encoding information. This process continues until all the LEDs in a certain first module 120a determine their own working parameters so as to present the corresponding lighting effect according to the working parameters of the target lighting module.

[0086] Therefore, the control information generated by the main controller 110 is transmitted sequentially along the first modules 120a connected in sequence. The communication LEDs 121 in multiple first modules 120a extract the target operating information corresponding to their respective first modules 120a from the control information, and then send the target operating information to the lighting modules 122 connected to the communication LEDs 121. The lighting modules 122 then send the target operating information to their respective lighting modules, and so on, until all lighting modules 122 in the first modules 120a corresponding to the communication LEDs 121 have received the target operating information. The communication LEDs 121 and the lighting modules 122 determine their own operating parameters in the target operating information based on their corresponding encoding information, thereby causing the entire lighting device to present the corresponding lighting effect.

[0087] When the lighting device 100 includes a large number of lighting modules 122, since the communication lamp beads 121 in different first modules 120a extract the corresponding target working information in the control information in parallel, the time difference between different lighting modules 122 receiving the target working information only comes from the time difference between the communication lamp beads 121 in different first modules 120a receiving the control information, thereby effectively reducing the time difference between different lighting modules 122 receiving the target working information.

[0088] To further improve the transmission efficiency of control information among the communication LEDs 121 in different first modules 120a, in some embodiments, the main controller 110 is connected to the communication LEDs 121 in the first module 120a, and the communication LEDs 121 in multiple first modules 120a are connected via a communication bus. This communication bus connection effectively improves the transmission efficiency of control information across different control modules and further reduces the time difference between different lighting modules 122 receiving the target operating information.

[0089] Furthermore, in some embodiments, please refer to Figure 4, which is a structural schematic diagram of another lighting device provided in an embodiment of this application. As shown in Figure 4, the lighting device 100 also includes an adapter 140, which is connected to the main controller 110. The adapter 140 is used to provide power to the main controller 110.

[0090] The power supply provided by adapter 140 can be either 5V or 12V. It is understood that the operating voltage of the power supply can be flexibly adjusted according to the actual needs of the lighting equipment 100. This application does not limit the specific value of the operating voltage provided by the power supply.

[0091] The communication LED 121 and the lighting module 122 operate at the same voltage.

[0092] When the operating voltage of the power supply is compatible with the operating voltage of the communication LED 121 and the lighting module 122 (for example, the operating voltage of the power supply is 5V, and the operating voltage of the communication LED 121 and the lighting module 122 is 5V), the adapter 140 provides the required operating voltage to the communication LED 121 and the lighting module 122 so that the communication LED 121 and the lighting module 122 can work according to the target operating parameters in the target operating information.

[0093] In some implementations, when the operating voltage of the power supply is compatible with the operating voltage of the communication LED 121 and the lighting module 122, and the power of the lighting module 122 is large (the number of communication LEDs 121 or the lighting module 122 is large and the brightness of the communication LEDs 121 and the lighting module 122 is large), the operating voltage provided by the power supply may not be able to ensure that the communication LEDs 121 and the lighting module 122 can work normally.

[0094] For example, when there are many communication LEDs 121 and lighting modules 122, and the operating voltage of the power supply is 5V, the voltage received by the LEDs (communication LEDs 121 and lighting modules 122) in the subsequent lighting modules after voltage drop will be much lower than 5V. This will cause the brightness of the LEDs at the end to weaken or not light up, affecting the lighting effect presented by the lighting device 100, and thus affecting the user experience.

[0095] Based on the above issues, please continue to refer to Figure 4. In some embodiments, the lighting device 100 also includes multiple voltage conversion modules 150, with the main controller 110 connected to one end of the first voltage conversion module and the other end of the first voltage conversion module connected to the first first module.

[0096] The two ends of the second voltage conversion module are respectively connected to two adjacent first modules 120a. The second voltage conversion module is any voltage conversion module 150 other than the first voltage conversion module among a plurality of voltage conversion modules 150. The two adjacent first modules 120a connected to the second voltage conversion module are determined according to the power of the lamp beads.

[0097] The power of the LED is related to its brightness and the number of LEDs. The number of LEDs refers to the number of LEDs included in the first module 120a.

[0098] The voltage conversion module 150 can be used to convert the power supply voltage of the power supply into the operating voltage required by the communication lamp 121 and at least one lighting module 122.

[0099] The voltage conversion module 150 can be a DC-DC converter circuit that converts DC power supply into DC voltage of the corresponding value to ensure that the communication lamp 121 and at least one lighting module 122 are provided with the required operating voltage.

[0100] The voltage conversion module 150 converts the operating voltage provided by the adapter 140 into the operating voltage required by the communication LED 121 and at least one lighting module 122, so as to avoid the communication LED 121 and at least one lighting module 122 failing to work properly due to excessively high or low operating voltage.

[0101] This application provides a lighting device and lighting system. The lighting device includes: a main controller and multiple first modules. Each of the multiple first modules includes a communication LED and at least one lighting module. The multiple first modules are connected sequentially via the included communication LEDs. The main controller is connected to the communication LED included in the first of the sequentially connected multiple first modules. The main controller is used to generate control information to control the lighting state of the multiple first modules and send the control information to the communication LED in the first first module. A target communication LED is used to receive the control information, determine target working information based on the control information, and send the target working information to at least one target lighting module. If the target first module corresponding to the target communication LED is not the last of the sequentially connected multiple first modules, the target LED sends the control information to the communication LED in the next connected first module. The target first module is any one of the multiple first modules, the target communication LED is the communication LED included in the target first module, and the at least one target lighting module is at least one lighting module included in the target lighting module. The target lighting module is used to determine the working parameters corresponding to the target lighting module based on the target working information and present corresponding lighting effects based on the working parameters corresponding to the target lighting module. Therefore, control information is transmitted through multiple communication LED beads. The communication LED beads then determine the target working information of the communication LED beads and the corresponding lighting modules based on the control information. This allows the communication LED beads and the corresponding lighting modules to determine the corresponding working parameters based on the target working information to present the corresponding lighting effects. This effectively reduces the time difference in determining the working parameters of different LED beads, thereby reducing the time difference in presenting light between different communication LED beads and lighting modules, and improving the user experience.

[0107] This application provides a lighting device and lighting system. The lighting device includes a main controller, multiple communication modules, and multiple lighting modules.

The main controller is connected to the first communication module in the sequentially connected communication modules. Each communication module is also connected to a corresponding lighting module.

A target communication module determines the target working information in the control information and, if the target communication module is not the last communication module in the sequentially connected communication modules, sends the control information to the next connected communication module. The target communication module can be any one of the multiple communication modules. A target lighting module operates according to the target working information. The target lighting module is the lighting module corresponding to the target communication module.
