Preferred embodiments of the present invention will be broadly described below with reference to the drawings. Moreover, the embodiments of the present invention are not limited to the following embodiments, and various various embodiments can be adopted without departing from the technical idea of the present invention.

The present embodiment first provides an illumination system. Hereinafter, with reference to FIG. 1, lighting systems provided in the present embodiment from various fields will be introduced.

Wireless Communication Network In this embodiment, each of the optical units 10 and the remote controller 20 has a wireless communication unit (Bluetooth (registered trademark) communication module) based on the Bluetooth (registered trademark) standard protocol. The plurality of optical units 10 and the plurality of optical units 10 and the remote control 20 are connected by a Bluetooth (registered trademark) mesh network (Bluetooth Mesh). Furthermore, the Bluetooth (registered trademark) mesh network in the present embodiment is a network topology built based on the low power consumption version of the Bluetooth (registered trademark) standard protocol 4.0 or higher, that is, the Bluetooth (registered trademark) low power consumption mesh network (BLE Mesh, Bluetooth Low Energy Mesh).

The Bluetooth (registered trademark) communication modules (10BLE, 20BLE) provided in each optical unit 10 and remote control 20 are both one grid of the Bluetooth (registered trademark) low power consumption mesh network, and the Bluetooth (registered trademark) low consumption The grids of the power mesh network can communicate with each other bi-directionally, and the Bluetooth (registered trademark) communication module 10BLE of the optical unit 10 can relay the signal of the Bluetooth (registered trademark) communication module 20BLE of the remote control 20, thereby: The remote controller 20 can transmit data through the network connection between the optical units 10, and the control signal is transmitted to the parts of the optical unit 10 outside the signal transmission operation distance of the remote controller 20 to implement the control.

In the traditional lighting control method, before going to bed at night, the lighting fixtures in the current room must be turned off before leaving. The user has to act in the dark until the lighting equipment in another room is turned on, which is not convenient for the user. On the other hand, according to the above mesh network connection, after moving to another room without turning off the light fixtures in the current room, the user can turn off the light in the previous room with the remote control 20 carried by him/her, allowing him to navigate in the dark. No need to move. It also reduces the usage demands that must be considered during the initial design layout of the luminaire.

Infrared Communication Network In the lighting system provided in this embodiment, group control is performed based on the BLE Mesh network. The independent control of each optical unit 10 is completed based on the interaction between the infrared transmission unit 20IR of the remote controller 20 as the grid of the BLE Mesh network and the infrared reception unit 10IR of the optical unit 10 as the grid of the BLE Mesh network. .

In this embodiment, each optical 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 transmitting a command to each optical unit 10 by infrared communication.

When the Bluetooth (registered trademark) communication module 20BLE of the remote controller 20 and the Bluetooth (registered trademark) communication module 10BLE of each light unit 10 in the lighting system can both establish a communication connection, and the remote controller 20 is used for independent control, A user typically selects a light unit 10 to perform single control from among the plurality of light units 10 of the lighting system. For a lighting system with a large number of light units 10 and a remote control 20 without a GUI (or with a simple GUI), this selection process becomes extremely cumbersome.

In a conventional lighting system, single control is usually performed using an infrared remote controller that is paired one-to-one with the light unit 10, but group control is interconnected via WiFi (registered trademark) using smartphones. The control of the lighting system as a whole must depend on a plurality of controllers and a plurality of control systems. When the infrared remote controls with which each light unit 10 is paired are integrated into the same remote control, the infrared light can be covered over a certain area and reflected off walls and other objects, instead of perfect point-to-point control. Therefore, the infrared signal is received by a plurality of adjacent optical units 10, causing a problem of difficulty in performing single control accurately.

To solve the above problem, in the lighting system provided in 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, the infrared receiving units 10IR of the adjacent optical units 10 are assigned to different data channels for data transfer, and the infrared signal transmitted from the infrared transmitting unit 20IR is Even if it is received by adjacent light units 10, it will not be decoded because the adjacent light units are set to different data channels, thereby avoiding erroneous settings for adjacent lighting fixtures. It is possible to improve the accuracy of single control.

In some embodiments, there is an upper limit on the number of light units 10 that can be included in the same control group, and the upper limit is allocated below the number of data channels. The above method allows different data channels to be assigned to each optical unit 10 within the same control group. Since different light units 10 are in different data channels, different data channels can be used to match different light units 10 one-to-one, so that a single infrared signal will not cause different light unit 10 responses. Therefore, it is possible to improve the directivity accuracy of the single control.

Light Unit In some embodiments, the light unit 10 is an incandescent lamp, a decorative incandescent lamp, a sealed bulb, an infrared lamp, a halogen lamp, an LED lamp, a fluorescent lamp, a daylight lamp, a sodium lamp, a xenon lamp, a ceiling lamp. , Chandeliers, Ceiling pendant lamps, Ceiling lamps, Recessed ceiling lamps, Wall lamps, Wall lamps, Direct wall lamps, Table lamps, Floor lamps, Street lamps, Garden lights, Door lamps, Flashlights, Pocket lights, Hand lamps, Search may be selected from one or more combinations of lights, spotlights, or any other suitable controllable light sources, and any suitable controllable and natural light sources, candles, oil Any suitable non-controllable light source, such as a lamp, and an accessory capable of changing the lighting conditions of the light source, such as a controllable blind curtain, lampshade, shielding plate, etc., may also be combined. It may be a controllable module or assembly in any one or more light sources or accessories.

Referring to FIG. 2, in the present embodiment, the light unit 10 is an LED lamp, and the LED lamp uses a PWM dimming circuit 102 to dim and control a light-emitting member 106 of the LED lamp through a driving power source 104 . In this embodiment, the scene can be preset at the time of shipment. For example, each can be constructed with a different brightness. It can also be set by the user himself. For example, it can be obtained by fixing and saving a single setting result.

In the present embodiment, the LED lamp (light unit 10) further has a Bluetooth (registered trademark) communication module 10BLE with low power consumption, and the Bluetooth (registered trademark) communication module 10BLE is the PWM dimming circuit 102 of the light unit 10. or integrated in the same master control chip 10C as the PWM dimming circuit 102, based on the control command acquired by the Bluetooth (registered trademark) communication module 10BLE, switch and dimming parameters of the light unit 10 can be adjusted. Integrating the PWM dimming circuit 102 into the Bluetooth (registered trademark) communication module 10BLE can effectively reduce the cost. In addition, a plurality of types of chips may be adopted and adapted respectively so that the integrated Bluetooth (registered trademark) communication module 10BLE and PWM dimming circuit 102 may be adapted to different types of optical units 10, or different types may be adapted. In order to reduce the cost of adapting the optical unit, a generic Bluetooth(R) module may be used and adapted in a manner to suit different peripheral circuits.

In some embodiments, for some light units 10 that at least partially rely on accessories to control light performance, the Bluetooth® communication module 10BLE also determines the operational status of the accessories. It can be communicatively connected to the control portion of that accessory so that it can be controlled. For example, it is communicatively connected to the driving part of the lampshade so that the degree of opening and closing of the lampshade can be adjusted.

In this embodiment, the optical unit 10 further comprises a mechanical switch 108 (eg, a wall switch), which is electrically connected to the optical unit 10 and can perform switch control on the optical unit 10 .

In addition, the master control chip 10C of the optical unit 10 in this embodiment integrates or connects the memory device 10MEMO, the master control chip 10C can acquire the switch state and dimming parameters of the optical unit 10, and Execution data relating to dimming parameters are stored in the memory device 10MEMO. In some embodiments, only the master control chip 10C of some light units 10 in the lighting system may be provided with the memory device 10MEMO, and the one or more master control chips provided with the memory device 10MEMO 10C can acquire execution data of other optical units 10 through a mesh network established by Bluetooth (registered trademark) communication module 10BLE, and store the execution data in memory device 10MEMO. By providing the memory device 10MEMO only in the master control chip 10C of some of the optical units 10, the hardware cost of the system can be effectively reduced.

In some embodiments, memory device 10MEMO may include a non-volatile memory device. For example, a read-only memory device (ROM), a programmable read-only memory device (PROM), an erasable programmable read-only memory device (EPROM), a flash memory device (FLASH) or programmed or Any other device capable of storing data can be included. The memory device may also include volatile memory devices. For example, it can include random access memory devices (RAM), static random access memory devices (SRAM), dynamic random access memory devices (DRAM) and synchronous dynamic random access memory devices (SDRAM), as well as other types. of RAM may be used for storage. The memory device 10MEMO can be realized by one memory device module or by a plurality of memory device modules, and may be a cloud memory device provided separately from the light unit 10 or the remote control 20. FIG.

The infrared receiving unit 10IR and the processor 10MCU of the optical unit 10 are connected to communicate with each other, and can acquire the user's single control command. Then, the setting result can be stored in the memory device 10MEMO.

Grouping This embodiment will be described by taking household lighting as an example. Among them, a plurality of light units 10 in the same lighting system are divided into two control groups based on their spatial position (in this embodiment, the room in which they are located is a grouping condition). Among them, the five light units 10 in the living room are divided into the first control group 1a, and the three light units in the bedroom are divided into the second control group 1b. It has a Bluetooth® communication channel connected to each other, and also has a Bluetooth® communication channel between at least some of the light units 10 in different control groups.

In another embodiment of the present invention, the lighting system can also be used for other types of lighting, such as commercial lighting, outdoor lighting, etc., to provide illumination for scenes in different spaces or areas. In addition, the grouping condition is not limited to the spatial position based on the light unit 10, but the actual usage logic (for example, radiant lamps that are separated from each other but emit light toward the same area are grouped) or their own characteristics. The grouping may be based on, for example, the color or intensity of lamp light. In addition, in this embodiment, the same light unit 10 is divided into a single control group in the lighting system, but in some embodiments of the present invention, the same light unit may be shared by different control groups. good. Also, the number of control groups is not limited to two employed in this embodiment, and three or four or more may be provided according to actual demand.

Remote Control Referring to FIG. 3, the remote control 20 used for the lighting system in this embodiment includes a grouping switch 200, a scene switch 202, a channel switching button 204, a feedback button 206, a dimming button 208, an infrared transmission unit 20IR, Bluetooth ( (registered trademark) communication module 20BLE, memory device 20MEMO, and processor 20MCU. Each button, the Bluetooth (registered trademark) communication module 20BLE, and the memory device 20MEMO are all connected to the input port of the processor 20MCU, and the Bluetooth (registered trademark) communication module 20BLE, the memory device 20MEMO, and the infrared transmission unit 20IR are further connected to the output of the processor 20MCU. connected to a port.

Among them, the grouping switch 200 is a manual switch, and the plurality of optical units 10 in the system are divided into two control groups and controlled respectively. Correspondingly, a two-stage manual switch is employed to switch between the two control groups. In other embodiments of the invention, more than three stage manual switches may be used, for example a four stage manual switch may be used to switch between four control groups. In addition, other gears that do not correspond to the control group may be added to enhance the control function.

The grouping switch 200 indicates the corresponding control group number in the interactive process with the user. For example, when the grouping switch 200 is in the position of the first control group 1a, in the grouping process, the current grouping operation instructs the grouped optical units 10 to be distributed to the first control group 1a. In the control process, the current control operation is instructed to be performed for the optical units 10 in the first control group 1a. In the process of canceling or initializing the grouping, the grouping of the optical units 10 in the first control group 1a is canceled or the initialization of the optical units 10 in the first control group 1a is instructed. In the single control process, one of the plurality of light units 10 of the first control group 1a is instructed to perform single control.

In the present embodiment, the scene switch 202 of the remote control 20 comprises a turn off button and two preset scene buttons for the user to press to turn off all light units in the corresponding control group ( off), 50% light intensity (scene 1 factory setting), or 100% light intensity (scene 2 factory setting). In alternate embodiments of the present invention, the number of buttons on scene switch 202 may also be added or reduced as needed for control functions. In this embodiment, the user can adopt a single adjustment method, after adjusting the dimming parameters of the light units 10 in the control group to a satisfactory state, modify the factory setting of the scene switches 202 such as scene 1 and scene 2. The dimming parameters of the light unit 10 are stored in the remote controller 20 or in the memory device 10MEMO or 20MEMO of the light unit 10 so that it can be done. For specific system settings and operation methods, refer to the flow chart portion of the method described later.

In some embodiments of the present invention, there are more remote controllers 20, and all of them can be used as a grid of the BLE Mesh network, and the setting and storage information between different remote controllers 20 can be kept in sync, and users can access each Control can be performed using a remote control 20 corresponding to the room.

In this embodiment, a scene control command is sent through the Bluetooth(R) communication module 20BLE in response to the scene switch being triggered. A single control command is transmitted through the infrared transmission unit 20IR in response to the dimming button 208 being triggered. Since the same remote controller 20 includes an infrared transmission unit 20IR and a Bluetooth (registered trademark) communication module 20BLE, the infrared transmission unit 20IR transmits a single control command, and the Bluetooth (registered trademark) communication module 20BLE transmits a scene control command. . The preferred signal transfer method assignment can be completed for various setting operations at the time of shipment, and the user does not need to manually select at the time of implementation.

In this embodiment, the channel switch button 204 of the remote controller 20 allows the user to manually select the data channel currently used by the infrared transmission unit 20IR of the remote controller 20 . The selection of data channels may be determined based on feedback through the BLE Mesh network of light units 10 . For example, the signal strength detection function of the BLE mesh network can be used, the remote control 20 moves close to a specific light unit location, and the strength of the Bluetooth® connection signal between the specific light unit and the remote control 20 exceeds the threshold. If it is detected to exceed, the data channel information of the specific optical unit is sent to the remote control 20, and the remote control 20 automatically selects the data channel currently used by the infrared transmission unit 20IR after receiving the data channel information. can be determined. Also, the channel indicator lamp 212 may emit notification information so as to notify the user to switch to the matching data channel and perform independent control. According to the signal strength detection function, in line with the grouping and the single execution of single control, the user can go near the light unit 10 to be controlled and directly press the corresponding dimming button 208 to control the target light unit 10 alone. It can be controlled accurately, is easy to operate and easy to use, and has high directional accuracy.

Method flow chart (initial setting method)
The present embodiment further provides an initialization method applicable to the above lighting system.

Referring to FIG. 4, the initialization method provided in this embodiment specifically includes the following steps:

S01 Power on.
After purchase and installation by the user, each light unit 10 and remote control 20 are turned on.

S02 Initialization Each optical unit 10 and remote control 20 read the initial data of the firmware and initialize the settings of the optical unit.

S03 Network construction Each optical unit 10 and the remote control 20 enter pairing standby mode, and in the pairing standby mode, the Bluetooth (registered trademark) communication module 10BLE of the optical unit 10 communicates with each other in the short-range communication mode. By setting a signal strength threshold in the short-range transmission mode, signals below the signal strength threshold are become ignored.

In this embodiment, the light unit 10 can detect the operation (or switch state) of its mechanical switch 108 and force the light unit 10 in response to said operation or state meeting a preset condition. be initialized. According to the above method, even if some optical units 10 are erroneously bundled with other networks, the mechanical switch 108 is used to trigger the initialization of the optical units 10, and the erroneously bundled optical units 10 are can be forcibly unbundled from other networks.

For example, the operation of repeatedly turning on and off the mechanical switch 108 within a certain period of time (or the detection of repeated switching of the switch state) is taken as the trigger operation for the initialization of the optical unit 10, and in response to detecting the trigger operation, The optical unit 10 is forcibly initialized to the shipping state and removed from the BLE Mesh network for which pairing has already been completed. In some embodiments, light units 10 in different rooms or areas are added to the same network in response to respective confirmations from those different rooms or areas.

S04 Confirmation of network construction results.
The user can obtain the network construction result by means of the indication lamps 110, 210 on the light unit 10 and the remote controller 20. FIG. After the pairing of the light unit 10 and the remote controller 20 is completed, the indicator lamps 110 and 210 on the light unit 10 and the remote controller 20 will notify the user of the network construction result by blinking, turning on/off, blinking frequency, and changing the notification lamp. to notify.

When the user confirms the success of the network construction with the feedback button 206, the process proceeds to the S05 grouping step. In the present embodiment, after successful network construction, indicator lamp 110 flashes once and then lights up as a preset notification method.

When the user cancels the result of network construction with the feedback button 206, the process moves to the S01 power-on step.

S05 Grouping.
The light unit 10 automatically or in response to a remote control 20 command enters the grouping setup mode.

In the grouping setting mode, for the grouping of light units 10 in any suitable manner, it is possible to organize a plurality of light units 10 in the lighting system into a plurality of control groups.

S06 Confirmation of grouping results.
When the user confirms the grouping result with the feedback button 206, the process proceeds to the S07 channel distribution step.

When the feedback button 206 cancels the grouping result, the process proceeds to the S05 grouping step.

S07 channel distribution step.
Through 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 each optical unit 10 to the data channel adopted by the infrared receiving unit 10IR. It is preferable to distribute different data channels to adjacent optical units 10 in the same control group so that the directivity accuracy of single control can be enhanced.

Method flow chart (group control method)
After the initial setting is completed, when the manual switch 200 on the remote controller 20 is manually moved to the first gear (group 1), the plurality of light units 10 in the first control group 1a corresponding to the gear are combined into one. Group controlled. In addition, in some embodiments, in conjunction with other switches of the remote controller 20, the operation of ungrouping the optical units 10 in the group (still in the network) and unbundling the network can also be realized. For example, when the manual switch 200 is manually moved to the first gear (group 1), the first control group 1a can be released when the user's predetermined action on the remote control is detected. Network unbundling operations can be performed at the optical unit 10 portion by activating mechanical components attached to the optical unit 10 to initialize one optical unit and remove bundling from the network. Also, it is possible to perform group operations from the remote control 20 portion. For example, the manual switch 200 can be manually moved to the first gear (group 1) to initialize all the optical units 10 in the first control group 1a and release the bundling from the network by a predetermined action.

Method flow chart (single control method)
For a system in which grouping has already been completed by the initial setting method, the present embodiment further provides a control method for performing single control using the remote controller 20 capable of performing group control. 5, the left side of FIG. 5 is the operation performed by the remote controller 20 in the single control method, and the right side of FIG. 5 is the operation performed by the light unit 10 in the single control method.

Normally, since the infrared transmission unit 20IR has directivity, when the remote control 20 is aimed at the target optical unit 10 to be independently controlled and then the dimming button 208 is pressed, the infrared mode is automatically activated. It can be activated to directly adjust the dimming parameters of the light unit 10 .

However, some of the optical units 10 are too close to each other, and the infrared signal for independent control emitted from the remote controller 20 is received by the multiple optical units 10 after being reflected, or the infrared signal is received by the multiple optical units 10 . May cover directly. The present embodiment also provides a single control method for such situations. The single control method includes the following steps:

In the S08 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 button 204 . In the signal detection mode, the remote control 20 can detect the signal strength of the Bluetooth® communication connection established by each light unit 10 and the remote control 20, and the signal strength of a particular Bluetooth® communication connection is higher than a threshold, or , the maximum value of the signal strength of each Bluetooth® communication connection, the spatial position of the corresponding specific light unit and the remote controller 20 is determined to be the closest.

S09 In the channel matching step, a signal is transmitted to the specific optical unit to notify the specific optical unit, and the data channel information currently used by the infrared receiving unit 10IR of the specific optical unit is transmitted through the BLE Mesh network. Send to the remote controller 20 . After the remote controller 20 receives the data channel information, it automatically matches the data channel adopted by its infrared transmission unit 20IR with the data channel of a specific light unit, or emits announcement information through the channel indicator lamp to match. Advertise the data channel settings to the user.

In the single control step S10, single control is performed on the specific light unit for which the communication connection has been established, and dimming of the specific light unit is performed based on the user's single control command generated by operating the dimming button 208. Adjust parameters.

In this embodiment, the remote controller 20 has a dimming button 208 that can adjust the brightness of the light unit 10 . In alternate embodiments of the present invention, remote control 20 may also include other dimming functions. For example, after establishing a communication control connection between the remote control 20 and a specific light unit, the remote control 20 can adjust at least one of the color temperature, turn-off delay function, and buzzer control function of the specific light unit.

S11 In a setting saving step, upon receipt of feedback confirmation information from the user's feedback button 206, the dimming parameter of a specific light unit is changed, and the changed dimming parameter is saved in the memory device 10MEMO or memory device 20MEMO, Then, the factory settings of the dimming parameters corresponding to the scene switches 202 such as scene 1 and scene 2 are corrected.

In the S12 scene generation step, a scene is formed in the control group based on the stored dimming parameters of the light units 10 in the same control group and stored in the memory device 20MEMO.

In some embodiments, the user can enter the scene setting mode by means of a scene setting key (not shown) on the remote control 20 and set the dimming parameters for any of the light units to be adjusted within the control group. After the single control is completed, the final single control result is determined, collectively generated into a scene, and the scene is stored in the memory device 20 MEMO, so that the scene setting defined by the user can be reproduced. Thus, the remote control 20 can be directly used by the scene switch 202 in the subsequent control process.

According to the above method, the control method provided in this embodiment can realize group control and single control for a complex lighting system by remote control 20 with no GUI or only a simple GUI. In addition, each optical unit 10 and each control group in the system can be controlled by the same remote controller 20, so that the degree of integration of control equipment can be greatly increased. In addition, the operation process is simple and easy to use, the directivity of the single control is highly accurate, and the scene defined by the user can be generated based on the single control result, so that the group control scene switch 202 can be used. can be used directly.

It should be noted that although in this embodiment the method of signal strength detection determines the particular light unit the user is currently trying to control, any other suitable light unit may be used in other embodiments of the present invention. You can also make that determination in any other way. For example, an infrared test signal may be sent in response to the infrared mode operation of the remote control, and the test signal does not include a single control command, but only tests the infrared signal reception status of each optical unit 10 . When the light unit 10 receives the infrared test signal, its indicator lamp 110 can notify the user that communication has been established. The user can adjust the spatial position, the direction of the remote control, etc. to ensure that only the indicator lamp 110 of the target light unit to be independently controlled is illuminated, thus ensuring the accuracy of the independent control. Alternatively, it is possible to ensure that single control is performed only for a single target light unit 10 by selecting from each light unit 10 with which communication has already been established by another switch.
