[0011] In order to make the objectives, technical solutions, and advantages of this application clearer, the following will further describe this application in detail with reference to the drawings. The described embodiments should not be regarded as limitations to this application. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0012] In the following description, reference is made to "some embodiments", which describe a subset of all possible embodiments. However, it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict. In the following description, the term "a plurality" refers to at least two.

[0013] In the following description, the terms "first / second" are merely used to distinguish similar objects and do not represent a specific order for the objects. It is understood that "first / second" may be interchanged in a specific order or sequence when permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used herein are for the purpose of describing the embodiments of this application only and are not intended to limit this application.

[0015] To meet the needs of users' lives and personalization, lighting devices have developed rapidly. In the related art, the control information generated by the controller for controlling the working state of the lamp beads is sequentially transmitted among the lamp beads in the lighting device, that is, the control information is transmitted from one lamp bead to the next lamp bead until the control information is transmitted to the last lamp bead. When the number of lamp beads is large, the time difference between the lamp beads connected in the front and the lamp beads connected in the back receiving the control information will be large, resulting in a large time difference in the change of the light, thereby affecting the light effect.

[0016] In another related art, a plurality of lamp beads directly communicate with the controller, that is, the controller directly sends the control information to the lamp beads to control the working state of the lamp beads. When the number of lamp beads is large, since each lamp bead has to communicate with the controller, the time difference for different lamp beads to work according to the control information is large, thereby affecting the light effect.

[0017] In another related art, the controller directly communicates with a plurality of relay boards, and the plurality of relay boards respectively communicate with the connected lamp beads to control the lamp beads to present corresponding light effects. However, a microcontroller unit (MCU) needs to be provided inside the relay board to perform corresponding control on the relay board. Since the microcontroller unit is added, the cost of the device is increased.

[0018] To improve the above problems, the present application provides an illumination device and an illumination system. The illumination device includes: a main controller, a plurality of communication modules, and a plurality of illumination modules. The plurality of communication modules correspond to the plurality of illumination modules one by one. The illumination module includes a plurality of lamp beads, where: the plurality of communication modules are connected in sequence, the main controller is connected to the first communication module among the plurality of communication modules connected in sequence, and each communication module among the plurality of communication modules is further connected to the corresponding illumination module; the main controller is used to generate control information for controlling the working state of the illumination device and send the control information to the first communication module; the target communication module is used to determine the target working information in the control information and, when the target communication module is not the last communication module among the plurality of communication modules connected in sequence, send the control information to the next connected communication module. The target communication module is any one of the plurality of communication modules; the target illumination module is used to work according to the target working information, and the target illumination module is the illumination module corresponding to the target communication module.

[0019] Thus, the plurality of communication modules directly communicate with the main controller to determine the target working information, and the illumination device directly communicates with the corresponding communication module to present the corresponding light effect according to the target working information, effectively reducing the time difference for different lamp beads to receive the target working information.

[0020] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application.

[0021] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of an illumination device provided by an embodiment of the present application. As Figure 1 shown, Figure 1 the illumination device 100 in

[0022] includes a main controller 110, a plurality of communication modules 120, and a plurality of illumination modules 130.

[0023] Among them, the plurality of communication modules 120 correspond to the plurality of illumination modules 130 one by one, and the illumination module 130 includes a plurality of lamp beads 131. The plurality of communication modules 120 are connected in sequence, the main controller 110 is connected to the first communication module among the plurality of communication modules 120 connected in sequence, and each communication module 120 among the plurality of communication modules 120 is further connected to the corresponding illumination module 130.

[0024] The target communication module is used to determine the target working information in the control information, and when the target communication module is not the last one among a plurality of sequentially connected communication modules, send the control information to the next connected communication module 120. The target communication module is any one of the plurality of communication modules 120.

[0025] The target lighting module is used to work according to the target working information. The target lighting module is the lighting module 130 corresponding to the target communication module.

[0026] The main controller 110 is a controller. In some embodiments, the user determines the presented lighting effect data of the lighting device according to actual needs (for example, the brightness, color, etc. of the lamp beads). The main controller 110 generates control information according to the lighting effect data determined by the user.

[0027] In some other embodiments, a plurality of lighting templates are pre-stored in the main controller 110, and the lighting templates can be pre-set by the user. For example, the lighting template can be that all the lamp beads 131 present red. After the user selects a suitable lighting template according to the application scenario, the main controller 110 can generate control information according to the selected lighting template by the user.

[0028] The control information may include multi-bit address information and lamp control status data (for example, the working parameters of the lamp beads 131). The main controller 110 transmits the generated control information to the first communication module 120, and the first communication module 120 then transmits the control information to the sequentially connected communication modules 120, so that all the communication modules 120 can receive the control information.

[0029] When the communication module 120 receives the control information, the communication module 120 determines the corresponding 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 corresponding to the target working information according to the corresponding address information to work, so as to present the corresponding lighting effect.

[0030] Specifically, the communication module 120 can be an address forwarding chip. Each address forwarding chip has a unique address information (for example, an address code). The address forwarding chip can perform comparison and verification according to the address information and the address information included in the control information. The address forwarding chip determines the data packet corresponding to the address information included in the control information and its own address information as the target working information.

[0031] That is to say, the target communication module is specifically used to extract information from the control information according to the address information corresponding to the target communication module to obtain the target working information.

[0032] After the target communication module extracts the target working information from the control information, it transmits the target working information to the target lighting module connected to the target communication module. That is, the target working information is transmitted to the lamp beads in the target lighting module. The lamp beads in the target lighting module are used to determine the target working parameters according to the target working information, so as to work according to the target working parameters (for example, on / off, presenting color or brightness, etc.).

[0033] In an embodiment of the present application, specifically, the lamp bead 131 in the target lighting module is specifically used to determine the corresponding address coding information, and determine the working parameters corresponding to the target working information according to the address coding information, so as to determine the target working parameters.

[0034] Each lamp bead 131 in the lighting module 130 has a unique address coding information. When the target communication module sends the target working information to the target lighting module, each lamp bead 131 in the target lighting module compares and verifies the address coding information in the target working information according to its own corresponding address coding information, so as to determine the data packet corresponding to the address coding information that is the same as the address coding information of the lamp bead 131 itself as the target working parameter, so that the lamp bead works according to the target working parameter, and then the corresponding lighting effect (for example, on / off, presenting color or brightness, etc.).

[0035] In some embodiments, multiple lamp beads can be connected in parallel. Since the lamp beads are all connected in parallel, the communication module can send the target working information to multiple lamp beads at the same time. The multiple lamp beads can together determine the corresponding address coding information, and then can determine the working parameters corresponding to the target working information according to the address coding information, and then can work according to the working parameters, which can reduce the time difference of the lamp beads receiving information, so that the time difference of the light changes of different lamp beads can be reduced, and thus the user experience can be improved.

[0036] In other embodiments, multiple lamp beads can include lamp beads connected in parallel and in series. Exemplarily, multiple lamp beads can be three lamp beads, where two lamp beads are connected in series and then connected in parallel with the remaining one lamp bead.

[0037] Thus, the control information generated by the main controller 110 is sequentially transmitted along the sequentially connected communication modules 120. The multiple communication modules 120 parallelly extract the corresponding target working information in the control information, so as to 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.

[0038] That is to say, the main controller 110 directly communicates with different communication modules 120, and different communication modules 120 directly communicate with the corresponding lamp beads 131, so that the lighting device 100 presents the corresponding lighting effect.

[0039] When the number of lamp beads 131 included in the lighting device 100 is large, since different communication modules 120 extract corresponding target working information in the control information in parallel, the time difference of different lamp beads 131 receiving the target working information comes from the time difference of different communication modules 120 receiving the control information, thereby effectively reducing the time difference of different lamp beads 131 receiving the target working information.

[0040] In some embodiments, between the main controller 110 and the first communication module, and between multiple communication modules 120 are connected through a communication bus. The main controller 110 is connected to the communication module 120 and between different communication modules 120 through a communication bus, which improves the transmission efficiency of control information between different communication modules 120, and further reduces the time difference of different lamp beads 131 receiving the target working information.

[0041] In some embodiments, please refer to Figure 2 , Figure 2 is a schematic structural diagram of another lighting device provided by an embodiment of the present application. As Figure 2 shown, the lighting device 100 further includes an adapter 140, and the adapter 140 is connected to the main controller 110. Among them, the adapter 140 is used to provide a power supply for the main controller 110.

[0042] The power supply provided by the adapter 140 can be 5V or 12V. It can be understood that the working voltage of the power supply can be flexibly adjusted according to the actual needs of the lighting device 100. The present application does not limit the specific value of the working voltage provided by the power supply.

[0043] When the working voltage of the power supply is adapted to the working voltage of the lamp bead 131 (for example, the working voltage of the power supply is 5V and the working voltage of the lamp bead 131 is 5V), the adapter 140 provides the required working voltage for the lamp bead 131, so that the lamp bead 131 can work according to the target working parameters in the target working information determined by the target communication module 120.

[0044] In some embodiments, when the working voltage of the power supply is adapted to the working voltage of the lamp bead 131 and the power of the lighting module 130 is large (the number of lamp beads 131 is large and the brightness of the lamp beads 131), the working voltage provided by the power supply may not ensure that the lamp beads 131 can work normally.

[0045] For example, when the number of lamp beads 131 is large and the working voltage of the power supply is 5V, after voltage drop, the voltage of the lamp beads 131 connected to the subsequent communication module 120 will be much lower than 5V, which will cause the brightness of the lamp beads 131 at the end to become weak or not light up.

[0046] Based on the above problems, please continue to refer to Figure 2 , in some embodiments, the lighting device 100 further includes a plurality of voltage conversion modules 150. The master 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.

[0047] Both ends of the second voltage conversion module are respectively connected to two adjacent communication modules 120. The second voltage conversion module is any one of the plurality of voltage conversion modules 150 except the first voltage conversion module, and the two adjacent communication modules 120 connected by the second voltage conversion module are determined according to the power of the lamp beads.

[0048] Among them, the power of the lamp beads is related to the brightness of the lamp beads and the number of lamp beads. The number of lamp beads is the number of lamp beads included in the lighting module 130.

[0049] The voltage conversion module 150 is used to convert the supply voltage of the power supply into the working voltage required by the lamp beads 131.

[0050] The voltage conversion module 150 can be a DCDC (DC-DC converter) circuit, which converts the DC power supply into a DC voltage with a corresponding voltage value to ensure the working voltage required by the lamp beads 131.

[0051] The working voltage provided by the adapter 140 is converted into the working voltage required by the lamp beads 131 through the voltage conversion module 150, so as to avoid the situation that the lamp beads 131 cannot work properly due to too high or too low working voltage of the lamp beads 131.

[0052] Please refer to Figure 3 , Figure 3 which is a schematic structural diagram of a lighting system provided by an embodiment of the present application. The lighting system 200 includes a mobile terminal 210 and the above lighting device 100. Specifically:

[0053] The mobile terminal 210 is used to generate a control instruction and send it to the lighting device 100;

[0054] The lighting device 100 is used to generate control information according to the control instruction.

[0055] Those skilled in the art can clearly understand that for the convenience and simplicity of description, the specific working process of the above lighting device can refer to the corresponding process in the foregoing method embodiment, which will not be repeated here.

The illumination device includes: a main controller, a plurality of communication modules, and a plurality of illumination modules. The plurality of communication modules correspond to the plurality of illumination modules one by one.
