Detailed ways

Hereinafter, the preferred embodiments of the present invention will be roughly described with reference to the drawings. In addition, the embodiments of the present invention are not limited to the following embodiments, and various embodiments within the scope of the technical concept of the present invention can be adopted.

This embodiment first provides a lighting system. The lighting system provided in this embodiment will be introduced from various aspects below with reference to FIG. 1.

Wireless communication network

In this embodiment, each optical unit 10 and remote controller 20 have a wireless communication unit (Bluetooth communication module) based on the Bluetooth standard protocol. The multiple optical units 10 and between the multiple optical units 10 and the remote controller 20 are connected by a Bluetooth mesh network (Bluetooth Mesh). Further, the Bluetooth mesh network in this embodiment is based on the Bluetooth standard protocol 4.0 or higher The network topology constructed by the low-power version of the Bluetooth low energy mesh network (BLE Mesh, Bluetooth Low Energy Mesh)

Each optical unit 10 and the Bluetooth communication module (10BLE and 20BLE) of the remote controller 20 is a node in the Bluetooth low energy mesh network, and the nodes in the Bluetooth low energy mesh network can communicate with each other in two directions. Transmission, the Bluetooth communication module 10BLE of the optical unit 10 can be used as a signal relay of the Bluetooth communication module 20BLE of the remote control 20, so that the remote control 20 can broadcast data through the network connection between the optical units 10 and send control signals to the remote control The device 20 signals the light unit 10 outside the working distance to implement control.

In the traditional lighting control method, before resting at night, you need to turn off the lighting in the current room and leave. If there is no other light source in the house, you need to turn off the lighting in the current room and turn on the lighting in another room. Acting in the dark environment, the user experience is poor. Through the above mesh network connection, the user can choose not to turn off the lights in the current room temporarily, and after moving to another room, use the remote control 20 to turn off the lights in the original room without acting in the dark. , It also reduces the use requirements to be considered in the initial design and layout of the lamps. Infrared communication network

In the lighting system provided in this embodiment, the grouping control is based on the BLE Mesh network operation, and the single lamp control of each light unit 10 is based on the infrared transmitting unit 20IR of the remote controller 20 as a node in the BLE Mesh network and also as the BLE Mesh network The interaction between the infrared receiving unit 10IR of the optical unit 10 of the middle node is completed.

In this embodiment, each light unit 10 is provided with an infrared receiving unit 10IR, and the remote controller 20 is provided with an infrared transmitting unit 20IR capable of sending instructions to each light unit 10 through infrared communication.

The Bluetooth communication module 20BLE of the remote controller 20 can establish a communication connection with the Bluetooth communication module 10BLE of each light unit 10 in the lighting system. Moreover, when the remote controller 20 is used for single lamp control, the user usually needs to download from multiple lighting systems. Among the light units 10, the light unit 10 whose single lamp control is attempted is selected. For a lighting system with a large number of light units 10 and the remote control 20 does not have a graphical user interface (or only has a simple graphical user interface), this selection process becomes extremely cumbersome.

In the existing lighting system, the infrared remote control paired with the light unit 10 is usually used to implement single lamp control, while the group control is performed on the wifi-connected light unit 10 using smart terminals. The control of the entire lighting system needs to rely on multiple The control device and multiple control systems have low integration and poor user experience. If the infrared remote controllers paired with each light unit 10 are integrated on the same remote controller, since infrared light is not a complete point-to-point control, it can cover a certain range and can be reflected by walls or other objects. Therefore, the infrared signal will be It is received by multiple adjacent light units 10, which in turn leads to the problem that single lamp control is difficult to accurately implement.

In order to solve the above problems, in the lighting system provided by this embodiment, the communication connection between the infrared receiving unit 10IR and the infrared transmitting unit 20IR has multiple data channels. In this embodiment, different data channels have different encoding and decoding methods. Therefore, by configuring the infrared receiving units 10IR of adjacent optical units 10 on different data channels to transmit data, even if the infrared signals emitted by the infrared transmitting unit 20IR are phased out. Adjacent multiple light units 10 receive it. Since multiple adjacent light units are set on different data channels, they will not be decoded, thereby avoiding incorrect settings of adjacent lamps. Improve the accuracy of single lamp control.

In some embodiments, the number of optical units 10 that can be included in the same control group has an upper limit, and the upper limit is configured to be less than or equal to the number of data channels. Through the above method, different data channels can be configured for each optical unit 10 in the same control group. Because different optical units 10 are in different data channels, different data channels can be used. A matching of different light units 10 makes that a single infrared signal does not cause the response of different light units 10, which further improves the accuracy of single lamp control pointing.

Light unit

In some embodiments, the light unit 10 may be selected from incandescent lamps, decorative incandescent lamps, closed bulbs, infrared lamps, plain lamps, LED lamps, fluorescent lamps, fluorescent lamps, sodium lamps, gas lamps, ceiling lamps, and branches. Chandelier, ceiling lamp, ceiling lamp, recessed ceiling lamp, wall lamp, wall lamp, wall hanging lamp, table lamp, floor lamp, street lamp, garden lamp, door lamp, flashlight, pocket lamp, portable lamp, searchlight, spotlight or any other One or a combination of suitable controllable light sources can also be any suitable controllable light sources mentioned above, natural light sources, candles, oil lamps and other suitable uncontrollable light sources and accessories that can change the lighting state of the light source, such as controllable light sources. The combination of the blinds, lampshades, baffles, etc. can also be a controllable module or component in any one or more of the light sources or accessories mentioned above.

Referring to FIG. 2, in this embodiment, the light unit 10 is an LED lamp, and the LED lamp uses a PWM dimming circuit 102 to perform dimming control on the light-emitting assembly 106 of the LED lamp via a driving power source 104. In this embodiment, the scenes may be preset at the factory, for example, constructed with different brightness respectively, or set by the user, for example, the result of a single lamp setting is fixed and saved.

In this embodiment, the LED lamp (light unit 10) also has a low-power Bluetooth communication module 10BLE, and the Bluetooth communication module 10BLE is electrically connected to the PWM dimming circuit 102 of the light unit 10, or to the PWM dimming circuit 102 Integrated in the same main control chip 10C, the switch and dimming parameters of the optical unit 10 can be adjusted based on the control instructions obtained by the Bluetooth communication module 10BLE. Integrating the PWM dimming circuit 102 with the Bluetooth communication module 10BLE can effectively reduce the cost. In addition, in order that the integrated Bluetooth communication module 10BLE and PWM dimming circuit 102 can be adapted to different types of light units 10, multiple types of chips can be used to adapt separately, or a general Bluetooth module can be used to cooperate with different peripheral circuits. Adaptation to reduce the cost of adapting different types of optical units.

In some embodiments, for some light units 10 that use accessories to control their light performance at least in part, the Bluetooth communication module 10BLE can also communicate with the control part of its accessories to control the working status of the accessories, for example, with the lampshade. The driving part is connected in communication to adjust the degree of opening and closing of the lampshade.

In this embodiment, the optical unit 10 further has a mechanical switch 108 (for example, a wall switch), and the mechanical switch 108 is electrically connected to the optical unit 10, and can perform switch control on the optical unit 10. In addition, the main control chip 10C of the optical unit 10 in this embodiment is integrated with or connected to the memory 10MEMO, and the main control chip 10C can obtain the switching state and dimming parameters of the optical unit 10, and collect the information about the switching state and dimming. The operating data of the parameters is stored in the memory 10MEMO. In some embodiments, a memory 10MEMO may also be provided in the main control chip 10C of only part of the light unit 10 in the lighting system, and the one or more main control chips 10C provided with the memory 10MEMO can be established via the Bluetooth communication module 10BLE. The mesh network obtains the operating data of other optical units 10 and stores the operating data in the memory 10MEMO. Setting the memory 10MEMO only in the main control chip 10C of some optical units 10 can effectively reduce the hardware cost of the system.

In some embodiments, the memory 10MEMO may include non-volatile memory, such as read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), flash memory (FLASH) ) Or any other device capable of storing program instructions or data with or without applied power. The memory can also include volatile memory, such as random access memory (RAM), static random access memory (SRAM), dynamic random access memory (DRAM) and synchronous dynamic random access memory (SDRAM), and other Type of RAM to achieve storage. The memory 10MEMO can be implemented using a single memory module or multiple memory modules, and can also be configured as a cloud memory separate from the optical unit 10 or the remote controller 20.

The infrared receiving unit 10IR of the light unit 10 and the processor 10MCU communicate with each other, and can obtain the user's single lamp control instruction. Based on the single lamp control instruction, the processor can use the PWM dimming circuit to adjust the dimming parameters of the light-emitting assembly 106 Set and save the setting result in the memory 10MEMO.

Grouping

This embodiment takes home lighting as an example for description, where multiple light units 10 in the same lighting system are divided into two control groups according to their spatial locations (in this embodiment, the room is the grouping condition). , Where the five light units 10 located in the living room are grouped into the first control group la, and the three light units located in the bedroom are grouped into the second control group lb, and the light units 10 in the same control group are evenly distributed. There are interconnected Bluetooth communication channels, and at least some of the optical units 10 in different control groups also have Bluetooth communication channels.

In other embodiments of the present invention, the lighting system can also be used in other lighting forms such as commercial lighting and outdoor lighting to provide lighting for scenes in different spaces or regions. In addition, the grouping conditions are not limited to the spatial position of the optical unit 10, and can also be based on actual use. Logic (for example, grouping the spotlights that are far away from each other but illuminating the same area) or their own characteristics (for example, according to light color and intensity). In addition, although in this embodiment, the same light unit 10 can be divided into a single control group in the lighting system, in some embodiments of the present invention, the same light unit can also be used by different control groups; and the control group The number is not limited to the two used in this embodiment, and three or more than four can be set according to actual needs.

remote control

3, the remote control 20 used in the lighting system in this embodiment includes a grouping control 200, a scene control 202, a channel switching key 204, a feedback key 206, a dimming key 208, an infrared emitting unit 20IR, a Bluetooth communication module 20BLE, and a memory 20MEMO and processor 20MCU. The buttons, the Bluetooth communication module 20BLE, and the memory 20MEMO are all connected to the input port of the processor 20MCU, and the Bluetooth communication module 20BLE, the memory 20MEMO, and the infrared transmitting unit 20IR are also connected to the output port of the processor 20MCU.

Among them, the grouping control 200 is a toggle switch, and the multiple optical units 10 in the system can be divided into two control groups to control respectively, and accordingly, a two-position toggle switch is used to switch between the two control groups. In other embodiments of the present invention, a three-position toggle switch may also be used, for example, a four-position toggle switch is used to switch between four control groups. In addition, other gears not corresponding to the control group can be added to enrich the control functions.

The group control 200 can indicate the number of the control group to be targeted during the interaction with the user. For example, when the grouping control 200 is in the position of the first control group la: In the grouping process, indicate that this grouping action will allocate the optical units 10 to be grouped to the first control group la; in the control process, indicate this time The control action will be implemented for the optical units 10 in the first control group la; in the process of releasing or initializing the grouping, it is indicated that the grouping of the optical units 10 in the first control group la will be released or the optical units in the first control group la will be initialized. 10; In the process of single-lamp control, it is indicated that single-lamp control will be implemented for one of the light units 10 of the first control group la.

In this embodiment, the scene control 202 of the remote control 20 includes a light-off button and two preset scene buttons, which can be pressed by the user to turn off all light units in the corresponding control group (light off), and 50% light intensity (scene 1 factory setting) or 100% light intensity (scene 2 factory setting). In other embodiments of the present invention, the number of buttons in the scene control 202 can also be increased or deleted according to the needs of the control function. In this embodiment, the user can adopt a single lamp adjustment method. After adjusting the dimming parameters of the light unit 10 in the control group to a satisfactory state, Save the dimming parameters of the light unit 10 in the remote controller 20 or the memory 10MEMO or 20MEMO of the light unit 10 to modify the factory settings of the scene control 202 of scene one and scene two. For specific system configuration and operation methods, see The method flow part later.

In some embodiments of the present invention, the remote controller 20 may also have multiple and all serve as nodes in the BLE Mesh network. The settings and saved information between different remote controllers 20 can be kept synchronized, and the user can use each The remote controller 20 corresponding to the room performs control.

In this embodiment, in response to the scene control being triggered, a scene control instruction is sent via the Bluetooth communication module 20BLE; in response to the dimming key 208 being triggered, a single light control instruction is sent via the infrared emitting unit 20IR. Since the same remote controller 20 has both an infrared emitting unit 20IR and a Bluetooth communication module 20BLE, the infrared emitting unit 20IR is used to send single light control commands, and the Bluetooth communication module 20BLE is used to send scene control commands, which can be configured for each setting action at the factory. A more preferred signal transmission mode is completed without the need for the user to manually select again during implementation.

In this embodiment, the channel switching key 204 of the remote controller 20 can allow the user to manually select the data channel currently used by the infrared emitting unit 20IR of the remote controller 20. The selection of the data channel can also be determined based on the feedback of the optical unit 10 via the BLE Mesh network. For example, the signal strength detection function of the BLE mesh network can be used. When the remote controller 20 is moved to a position close to the specific optical unit, if it detects When the signal strength of the Bluetooth connection between the specific light unit and the remote control 20 exceeds the threshold, the data channel information of the specific light unit is sent to the remote control 20, and the remote control 20 can automatically determine the infrared light after receiving the data channel information. The data channel currently used by the transmitting unit 20IR may also use the channel indicator 212 to send out a prompt message to prompt the user to switch to a matching data channel to implement single lamp control. Through the signal strength detection function, in conjunction with the independent operation of grouping and single lamp control, the user only needs to approach the light unit 10 to be controlled and directly press the corresponding dimming key 208 to accurately implement single lamp control on the target light unit 10 , The operation is simple and convenient and the pointing accuracy is high.

_^ The method of process stream (initial setting method)

This embodiment also provides an initial setting method applicable to the above-mentioned lighting system.

Referring to FIG. 4, the initial setting method provided by this embodiment specifically includes the following steps:

501. Power on.

After the user purchases and installs, the light units 10 and the remote controller 20 are powered on.

502. Initialization

Each light unit 10 and the remote controller 20 read the initial data in the firmware and initialize the light unit settings. S03. Network construction

Each optical unit 10 and the remote controller 20 enter the pairing waiting mode. In the pairing waiting mode, the Bluetooth communication module 10BLE of the optical unit 10 communicates with each other in the short-distance broadcasting mode. In the short-distance broadcasting mode, the signal strength threshold is set to be lower than the signal strength. The intensity threshold signal will be ignored to reduce the possibility of the light unit 10 to be paired being mistakenly bound by the network of other lighting systems.

In this embodiment, the optical unit 10 can detect the action (or switch state) of its mechanical switch 108, and in response to the foregoing action or state meeting a preset condition, the optical unit 10 is forcibly initialized. Through the above method, even if some of the optical units 10 are mistakenly bound by other networks, their mechanical switches 108 can be used to trigger the initialization of the optical units 10 to force the optical units 10 that have been mistakenly bound to be unbound from other networks.

For example, the action of repeatedly opening and closing the mechanical switch 108 within a certain period of time (or detection of repeated switching of the switch state) can be used as a trigger action for the initialization of the light unit 10. In response to detecting the trigger action, the light unit 10 will be forcibly It is initialized to the factory state and removed from the BLE Mesh network that has been paired. In some embodiments, in response to separate confirmations from different rooms or areas, the optical units 10 in these different rooms or areas are added to the same network.

S04 confirms the network construction result.

The user can obtain the network construction result through the indications of the light unit 10 and the indicator lights 110, 210 on the remote control 20. If the light unit 10 and the remote control 20 are paired, the indicator lights 110 and 210 on the light unit 10 and the remote control 20 will notify the user of the network construction result by means of flashing behavior, on and off, flashing frequency, and breathing light changes.

If the user uses the feedback key 206 to confirm that the network is successfully established, then go to the S05 grouping step. In this implementation mode, after the network is successfully established, the indicator light 110 will flash once and then light up as a predetermined prompt.

If the user feedback key 206 cancels the network construction result, return to S01 power-on step.

S05 grouping.

The optical unit 10 enters the group setting mode automatically or in response to an instruction from the remote controller 20. In the group setting mode, any suitable way can be used to group the light units 10, and the multiple light units 10 in the lighting system are organized into several control groups.

S06 confirms the grouping result.

If the user uses the feedback key 206 to confirm the grouping result, go to the S07 channel allocation step; if the user uses the feedback key 206 to cancel the grouping result, go to the S05 grouping step. S07 channel allocation steps.

Using the BLE Mesh network, the remote controller 20 can establish a point-to-point connection with each optical unit 10 in the same control group, and set the data channel used by the infrared receiving unit 10IR for each optical unit 10. Preferably, different data channels are allocated to adjacent light units 10 in the same control group to improve the pointing accuracy of single lamp control.

Method flow (group control method)

After the initial setting is completed, when the toggle switch 200 on the remote controller 20 is toggled to the first gear position (group one), several light units 10 in the first control group la corresponding to the gear position can be used as Group control as a whole. In addition, in some implementation manners, other controls of the remote controller 20 may also be used to implement the operations of ungrouping the optical units 10 in the group (still in the network) and unbinding the network. For example, when the toggle switch 200 is toggled to the first gear (group one), if a predetermined action of the user on the remote control is detected, the first control group la can be cancelled. The network unbinding operation can be activated and implemented at the optical unit 10 by using mechanical components installed on the optical unit 10 to initialize a single optical unit and unbind from the network; it can also be performed in groups from the remote control 20, for example, The toggle switch 200 is toggled to the first gear (group one), and through a predetermined action, all the optical units 10 in the first control group la are initialized and unbound from the network.

Method flow (single lamp control method)

For systems that have been grouped by the above initial setting method, this embodiment also provides a control method for implementing single lamp control by using the remote controller 20 capable of grouping control. Referring to Fig. 5, the left side of Fig. 5 shows the actions performed by the remote controller 20 in the single lamp control method, and the right side of Fig. 5 shows the actions performed by the light unit 10 in the single lamp control method.

Under normal circumstances, due to the directivity of the infrared emitting unit 20IR, after the remote controller 20 is aimed at the target light unit 10 that is trying to implement single-lamp control, pressing the dimming key 208 can automatically activate the infrared mode, directly to the light unit 10 Adjust the dimming parameters.

However, due to some situations where part of the light units 10 are too close to each other, the infrared signal sent by the remote controller 20 for single lamp control can be received by multiple light units 10 after being reflected, or the infrared signal can be directly covered Multiple light units 10. This embodiment also provides a single lamp control method for these situations, and the single lamp control method includes the following steps:

S08. In the signal detection step, the signal detection mode of the remote controller 20 is activated in response to the user's operation of long pressing the channel switching key 204. In the signal detection mode, the remote controller 20 can detect the signal strength of the Bluetooth communication connection established by each optical unit 10 and the remote controller 20, if the signal strength of the specific Bluetooth communication connection is higher than the threshold, or is less than the signal strength of each Bluetooth communication connection Biggest Value, it is determined that the spatial position of the corresponding specific light unit and the remote controller 20 is closest.

S09. Channel matching step, broadcast a signal for the specific optical unit, notify the specific optical unit, and send the data channel information currently used by the infrared receiving unit 10IR of the specific optical unit to the remote controller 20 via the BLE Mesh network. After the remote control 20 receives the data channel information, it automatically matches the data channel used by its infrared emitting unit 20IR with the data channel setting of the specific light unit, or sends out a prompt message through the channel indicator to remind the user of the matching Data channel setting.

S10 Single-lamp control step, implement single-lamp control on the specific light unit with the communication connection established, and adjust the dimming parameters of the specific light unit according to the single-lamp control command generated by the user through the operation of the dimming key 208.

In this embodiment, the remote controller 20 has a dimming key 208, which can adjust the brightness of the light unit 10. In other embodiments of the present invention, the remote control 20 may also have other dimming functions. For example, after the communication control connection between the remote control 20 and a specific light unit is established, the remote control 20 can at least adjust the specific light unit One or more of the color temperature, delayed light-off function, and buzzer control function.

S11 Setting saving step, if receiving the confirmation message fed back by the user using the feedback key 206, change the dimming parameters of the specific light unit and save the modified dimming parameters in the memory 10MEMO or the memory 20MEMO, and then perform the scene 1 The factory settings of the dimming parameters corresponding to the second-class scene control 202 are modified.

In the S12 scene generation step, based on the saved dimming parameters of each light unit 10 in the same control group, a scene is created for the control group and stored in the memory 20MEMO.

In some embodiments, the user can use the scene setting button (not shown) on the remote control 20 to enter the scene setting mode. After the light units in the control group whose dimming parameters need to be adjusted are all controlled by a single lamp, The final single lamp control result is determined, summarized and generated as a scene, and the scene is saved in the memory 20MEMO for the remote control 20 to use the scene control 202 to directly call in the subsequent control process to reproduce the user-defined scene setting set.

Through the above methods, the control method provided by this embodiment can utilize the remote controller 20 without a graphical user interface or with only a simple graphical user interface to realize group control and single lamp control for a complex lighting system. Moreover, the control of each optical unit 10 and each control group in the system can be implemented using the same remote controller 20, which greatly improves the integration of control equipment. Furthermore, the operation process is simple and convenient, and the pointing accuracy of the single lamp control is high. Based on the single lamp control result, a user-defined scene can also be generated for the scene control 202 of group control to be directly called. It should be noted that although the signal strength detection method is adopted in this embodiment to determine the specific light unit controlled by the user's current view, in other embodiments of the present invention, any other suitable method may also be used for the determination. . For example, in response to the operation of the infrared mode of the remote control, an infrared test signal can be sent out,

The test signal does not include a single lamp control command, and is only used to test the reception of the infrared signal of each optical unit 10. If the optical unit 10 receives an infrared test signal, its indicator light 110 can be used to prompt the user to establish a communication link. The user can ensure that only the indicator light 110 of the light unit whose target implements single-lamp control is lit by adjusting the spatial position, the orientation of the remote control, etc., to ensure the accuracy of single-lamp control, or they can also use other controls to change Select among the light units 10 that establish a communication link to ensure that the single lamp control is only for a single target light unit 10.
