With the advent of the intelligent industry and the internet of things era, more and more electrical products are incorporated into the internet of things for intelligent unified management. Similar changes also occur in the lighting industry, and with the popularization of the internet of things technology, communication modules are also installed or connected to more and more lighting fixtures to meet the requirements of intellectualization and interconnection.

Meanwhile, for indoor or outdoor lighting, users no longer satisfy the simple requirement of obtaining sufficient illumination with a single lamp, but increasingly focus on the decorative function of the lighting itself. By utilizing the combination of parameters such as the type, style, dimming performance and the like of a group of light units (such as light sources of lamps and lanterns, and components capable of changing the illumination state of the light sources, such as shutters, lampshades and baffles), various complicated and attractive illumination scenes can be combined, and the technical and artistic combination is popularized in the fields of commercial illumination and household illumination.

While group control can facilitate the user in constructing and reproducing complex and aesthetically pleasing lighting scenes, single lamp control is still not abandoned in most cases from the standpoint of operational and control flexibility. For the above reasons, as the control system needs to satisfy the requirements of both single-lamp control and group control, the number of selectable or adjustable items that need to interact with the user becomes more and more, and the system to be implemented becomes more and more complex.

The user can not only open a certain control to implement single-lamp control on the corresponding light unit, but also compile a plurality of light units into an independent control group, store the control group information compiled by the user, and further implement grouping control by taking the control group as a unit.

However, the intelligent mobile terminal is adopted to implement the control of the lighting system, on one hand, the cost of making software, a graphical user interface and the like is high, and on the other hand, part of countries and regions with insufficient popularization degree of the intelligent mobile phone and certain people with specific use habits (such as the elderly) do not tend to use the intelligent mobile terminal for installation and control, so that the terminal still faces a lot of difficulties when being applied to practical popularization.

Detailed Description

Hereinafter, preferred embodiments of the present invention will be described in general with reference to the accompanying drawings. The embodiments of the present invention are not limited to the following embodiments, and various embodiments within the technical concept of the present invention can be adopted.

The present embodiment first provides an illumination system, which is described below in various aspects with reference to fig. 1.

Wireless communication network

In the present embodiment, each of the light unit 10 and the remote controller 20 has a wireless communication unit (bluetooth communication module) based on the bluetooth standard protocol. The plurality of optical units 10 and the remote controller 20 are connected by a Bluetooth Mesh network (Bluetooth Mesh), and further, the Bluetooth Mesh network in this embodiment is a network topology constructed based on a Low power consumption version of Bluetooth standard protocol of 4.0 or more, that is, a Bluetooth Low Energy Mesh network (BLE Mesh).

Each of the bluetooth communication modules (10BLE and 20BLE) of the optical unit 10 and the remote controller 20 is a node in the bluetooth low energy mesh network, the nodes in the bluetooth low energy mesh network can communicate with each other in two directions, and 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 controller 20, so that the remote controller 20 can transmit control signals to the optical unit 10 outside the signal transmission working distance of the remote controller 20 by means of network connection broadcast data between the optical units 10 to implement control.

In a traditional lamp control mode, before a rest at night, a lamp in a current room needs to be turned off and left, if no other light source irradiates indoors, a user needs to move in a dark environment in the period from turning off the lamp in the current room to turning on the lamp in another room, and user experience is poor. By the above mesh network connection, the user can choose not to turn off the lamps in the current room, and turn off the lamps in the original room by using the portable remote controller 20 after moving to another room, without moving in a dark environment, thereby reducing the use requirements of the lamps to be considered in the initial design layout process.

Infrared communication network

In the lighting system provided in the present embodiment, the group control is performed based on the BLE Mesh network, and the single-lamp control of each light unit 10 is performed based on the interaction between the infrared transmitting unit 20IR of the remote controller 20 serving as a node in the BLE Mesh network and the infrared receiving unit 10IR of the light unit 10 also serving as a node in the BLE Mesh network.

In the present 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 transmitting an instruction to each light unit 10 through infrared communication.

The bluetooth communication module 20BLE of the remote controller 20 and the bluetooth communication module 10BLE of each light unit 10 in the lighting system are all capable of establishing a communication connection, and when the remote controller 20 is used as a single-lamp control, a user usually needs to select the light unit 10, which the user tries to implement the single-lamp control, from among the plurality of light units 10 of the lighting system. For lighting systems with a large number of light units 10 and a remote control 20 without a graphical user interface (or with a simple graphical user interface only), this selection process becomes extremely cumbersome.

In the existing lighting system, single-lamp control is usually implemented by using infrared remote controllers which are paired with the light units 10 one by one, while group control is performed by using intelligent terminals for the light units 10 interconnected by wifi, the control of the whole lighting system needs to depend on a plurality of control devices and a plurality of sets of control systems, the integration level is low, and the user experience is poor. If the infrared remote controllers paired with the light units 10 are integrated on the same remote controller, since the infrared light is not completely controlled point-to-point, the infrared light can cover a certain range and can be reflected by a wall surface or other objects, and therefore, infrared signals are received by a plurality of adjacent light units 10, and the problem that the single-lamp control is difficult to implement accurately is caused.

In order to solve the above problem, the present embodiment provides a lighting system in which the communication connection between the infrared receiving unit 10IR and the infrared transmitting unit 20IR has a plurality of data channels. In this embodiment, the encoding and decoding modes of different data channels are different, and therefore, by configuring the IR receiving units 10IR of the adjacent light units 10 on different data channels to transmit data, even if the IR signals transmitted by the IR transmitting units 20IR are received by the adjacent light units 10, since the adjacent light units are set to be on different data channels, the decoding cannot be performed, and thus, the erroneous setting of the adjacent lamp is avoided, and the accuracy of single-lamp control is improved.

In some embodiments, the number of light units 10 that can be programmed in the same control group has an upper limit value configured to be less than or equal to the number of data lanes. In the above manner, different data channels can be configured for the respective light units 10 within the same control group. Because different light units 10 are located in different data channels, different data channels can be used to match different light units 10 one by one, so that a single infrared signal does not cause the response of different light units 10, and the pointing accuracy of single-lamp control is further improved.

Light unit

In some embodiments, the light unit 10 may be one or a combination of several selected from incandescent lamps, decorative incandescent lamps, enclosed bulbs, infrared lamps, halogen lamps, LED lamps, fluorescent lamps, sodium lamps, xenon lamps, ceiling lamps, chandeliers, ceiling lamps, embedded ceiling lamps, wall-hung lamps, desk lamps, floor lamps, street lamps, garden lamps, door lamps, flashlights, pocket lamps, hand lamps, searchlights, spotlights, or any other suitable controllable light source, any suitable controllable light source as described above, and any suitable uncontrollable light source such as natural light sources, candles, oil lamps, and accessories capable of changing the lighting state of the light source, such as controllable blinds, shades, blinds, etc., and may also be controllable modules or components of any one or more of the light sources or accessories described above.

Referring to fig. 2, in the present embodiment, the light unit 10 is an LED lamp, and the LED lamp performs dimming control on a light emitting element 106 of the LED lamp through a driving power supply 104 by using a PWM dimming circuit 102. In this embodiment, the scene may be factory-preset, for example, constructed with different brightness, or may be set by the user, for example, by fixing and storing the result of the single lamp setting.

In this embodiment, the LED lamp (light unit 10) further includes a bluetooth communication module 10BLE with low power consumption, and the bluetooth communication module 10BLE is electrically connected to the PWM dimming circuit 102 of the light unit 10, or is integrated with the PWM dimming circuit 102 in the same main control chip 10C, and can adjust the on/off and dimming parameters of the light unit 10 based on a control command obtained by the bluetooth communication module 10 BLE. The PWM dimming circuit 102 is integrated with the bluetooth communication module 10BLE, so that the cost can be effectively reduced. In addition, in order to make the integrated bluetooth communication module 10BLE and PWM dimming circuit 102 adaptable to different types of light units 10, multiple types of chips may be adapted respectively, or a general bluetooth module may be adapted to cooperate with different peripheral circuits to reduce the cost of adapting to different types of light units.

In some embodiments, for some light units 10 that at least partially control their light performance by using an accessory, the bluetooth communication module 10BLE may further be in communication connection with a control portion of its accessory to control the operating state of the accessory, for example, in communication connection with a driving part of a lampshade to adjust the opening and closing degree of the lampshade.

In the present embodiment, the optical unit 10 further includes a mechanical switch 108 (for example, a wall switch), and the mechanical switch 108 is electrically connected to the optical unit 10 and can switch and control the optical unit 10.

In addition, the memory 10MEMO is integrated or connected to the main control chip 10C of the light unit 10 in the present embodiment, and the main control chip 10C can acquire the switching state and the dimming parameter of the light unit 10 and store the collected operation data about the switching state and the dimming parameter in the memory 10 MEMO. In some embodiments, the memory 10MEMO may also be disposed in the main control chip 10C of only a part of the light units 10 in the lighting system, and the one or more main control chips 10C disposed with the memory 10MEMO can acquire the operation data of other light units 10 via the mesh network established by the bluetooth communication module 10BLE and store the operation data in the memory 10 MEMO. The memory 10MEMO is only arranged in the main control chip 10C of a part of the optical units 10, so that the hardware cost of the system can be effectively reduced.

In some embodiments, memory 10MEMO may comprise a non-volatile memory, such as a read-only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), a FLASH memory (FLASH), or any other device capable of storing program instructions or data with or without an application power. The memory may 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), although other types of RAM may also be used to implement the storage. The memory 10MEMO may be implemented using a single memory module or a plurality of memory modules, and may be configured as a cloud memory separate from the light unit 10 or the remote controller 20.

The infrared receiving unit 10IR of the light unit 10 is communicatively connected to the processor 10MCU, and can obtain a single lamp control command of a user, and the processor can set a dimming parameter of the light emitting module 106 by the PWM dimming circuit based on the single lamp control command, and store the setting result in the memory 10 MEMO.

Grouping

The present embodiment is described by taking home lighting as an example, wherein a plurality of light units 10 in the same lighting system are divided into two control groups according to their spatial positions (in the present embodiment, the room where the light units are located is a grouping condition), wherein five light units 10 located in the living room are divided into a first control group 1a, five light units located in the bedroom are divided into a second control group 1b, each light unit 10 in the same control group has an interconnected bluetooth communication channel, and at least some light units 10 in different control groups also have bluetooth communication channels.

In other embodiments of the present invention, the illumination system may also be used in other forms of illumination, such as commercial illumination, outdoor illumination, etc., to provide illumination for scenes in different spaces or areas. The grouping condition is not limited to the spatial position of the light unit 10, and may be based on an actual use logic (for example, a group of spot lights that are distant from each other but emit light to the same area), or a characteristic thereof (for example, a color and intensity of light). Furthermore, although in the present embodiment the same light unit 10 may be grouped in a single control group in the lighting system, in some embodiments of the invention the same light unit may be shared by different control groups; the number of the control groups is not limited to two in the present embodiment, and three or more control groups may be provided according to actual needs.

Remote controller

Referring to fig. 3, the remote controller 20 used in the lighting system in the present 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, a memory 20MEMO, and a processor 20 MCU. Each button, bluetooth communication module 20BLE, memory 20MEMO all are connected with the input port of treater 20MCU, and bluetooth communication module 20BLE, memory 20MEMO and infrared emission unit 20IR still are connected with the output port of treater 20 MCU.

The grouping control 200 is a toggle switch, and the plurality of light units 10 in the system can be divided into two control groups to be controlled respectively, and accordingly, the two control groups are switched by using the two-position toggle switch. In other embodiments of the present invention, more than three-position toggle switches may be used, for example, four-position toggle switches may be used to switch between four control groups. In addition, other gears which do not correspond to the control group can be added to enrich the control function.

The grouping control 200 can indicate the number of control groups to be targeted during interaction with the user. For example, when the grouping control 200 is in the position of the first control group 1 a: in the grouping process, indicating that the grouping action is to allocate the optical units 10 to be grouped into the first control group 1 a; in the control process, it is indicated that this control action is to be performed for the light units 10 in the first control group 1 a; in the release or initialization grouping process, it is indicated that the grouping of the light units 10 in the first control group 1a is to be released or the light units 10 in the first control group 1a are initially set; during the single-lamp control, it is indicated that the single-lamp control is to be implemented for one of the light units 10 of the first control group 1 a.

In this embodiment, the scene control 202 of the remote controller 20 includes a light-off key and two preset scene keys, which can be pressed by a user to turn off (light-off) all light units in the corresponding control group, and 50% light intensity (factory setting of scene one) or 100% light intensity (factory setting of scene two). In other embodiments of the present invention, the number of buttons in the scene control 202 may be increased or decreased according to the need of the control function. In this embodiment, a user may adopt a single-lamp adjustment mode, after adjusting the dimming parameters of the light units 10 in the control group to a satisfactory state, store the dimming parameters of the light units 10 in the remote controller 20 or the memory 10MEMO or 20MEMO of the light units 10, and modify the factory settings of the scene controls 202 of the first scene, the second scene, and the like, where specific system configuration and operation modes refer to the following method flow part.

In some embodiments of the present invention, the remote controller 20 may further have a plurality of remote controllers, each of which is used as a node in the BLE Mesh network, and the set and stored information between different remote controllers 20 may be kept synchronized, so that the user may perform control by using the remote controller 20 corresponding to each room.

In this embodiment, in response to the scene control being triggered, the bluetooth communication module 20BLE sends a scene control instruction; in response to the dim key 208 being activated, a single lamp control command is sent via the infrared emitting unit 20 IR. Because the same remote controller 20 has the infrared emission unit 20IR and the bluetooth communication module 20BLE, the infrared emission unit 20IR is used to transmit the single lamp control instruction, and the bluetooth communication module 20BLE is used to transmit the scene control instruction, a more preferable signal transmission mode can be configured for each set action when the remote controller leaves a factory, and a user does not need to manually select the signal transmission mode again when the remote controller is implemented.

In this embodiment, the channel switching key 204 of the remote controller 20 enables 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 may also be determined according to feedback of the light unit 10 through the BLE Mesh network, for example, a signal strength detection function of the BLE Mesh network may be used, when the remote controller 20 is moved to a position close to a specific light unit, if it is detected that the signal strength of the bluetooth connection between the specific light unit and the remote controller 20 exceeds a threshold value, the data channel information of the specific light unit is sent to the remote controller 20, after the remote controller 20 receives the data channel information, the data channel currently used by the infrared emission unit 20IR may be automatically determined, and a channel indicator lamp 212 may also be used to send a prompt message to prompt the user to switch to a matched data channel to implement single-lamp control. Through the signal intensity detection function, the independent operation of grouping and single lamp control is matched, a user only needs to approach the light unit 10 to be controlled and directly presses the corresponding dimming key 208, the single lamp control can be accurately implemented on the target light unit 10, the operation is simple and convenient, and the pointing precision is high.

Method flow (initial setting method)

The present embodiment also provides an initial setting method applicable to the above-described illumination system.

Referring to fig. 4, the initial setting method provided in the present embodiment specifically includes the following steps:

and S01, electrifying.

After purchase and installation, the user turns on the power supply to each light unit 10 and the remote controller 20.

S02. initialization

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

S03. network establishment

Each light unit 10 and the remote controller 20 enter a pairing waiting mode, in which the bluetooth communication module 10BLE of the light unit 10 communicates with each other using a short-distance broadcast mode, and in the short-distance broadcast mode, by setting a signal intensity threshold, a signal smaller than the signal intensity threshold is ignored, so as to reduce the possibility that the light unit 10 to be paired is misbound by networks of other lighting systems.

In the present embodiment, the optical unit 10 can detect the operation (or the switching state) of the mechanical switch 108, and forcibly initialize the optical unit 10 in response to the operation or the state satisfying a preset condition. In the above manner, even if some of the optical units 10 are misbound by other networks, the mechanical switch 108 thereof can be used to trigger the initialization of the optical unit 10, and the optical unit 10 that has been misbound can be forcibly unbound from other networks.

For example, the action of repeatedly opening and closing the mechanical switch 108 for a certain period of time (or the detection of repeated switching of the switch state) may be used as a trigger action for initializing the optical unit 10, and in response to the detection of the trigger action, the optical unit 10 is forcibly initialized to the factory state and removed from the paired BLE Mesh network. In some embodiments, light units 10 in different rooms or areas are joined in the same network in response to separate acknowledgements from those different rooms or areas.

S04 confirms the result of the networking.

The user can know the result of the network establishment through the light unit 10 and the indication of the

indicator lamps

110, 210 on the remote controller 20. If the light unit 10 and the remote controller 20 are paired, the indicator lights 110 and 210 on the light unit 10 and the remote controller 20 notify the user of the networking result through blinking behaviors, turning on and off, blinking frequency, breathing light changes, and the like.

If the user confirms the success of the network establishment using the feedback key 206, the process goes to S05. In the present embodiment, after the network is successfully established, the indicator light 110 blinks once and then lights up as a predetermined prompting method.

If the user feedback key 206 cancels the network establishment result, the power-on step of S01 is returned to.

S05.

The light unit 10 enters the group setting mode automatically or in response to an instruction of the remote controller 20.

In the grouping setting mode, the programming of the plurality of light units 10 in the lighting system into a number of control groups for the grouping of light units 10 may be achieved in any suitable way.

S06 confirms the grouping result.

If the user confirms the grouping result using the feedback key 206, the flow goes to S07 channel assignment step;

if the grouping result is canceled by using the feedback key 206, the flow goes to S05 grouping step.

And S07 channel allocation step.

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

Method flow (packet control method)

After the initial setting is completed, when the toggle switch 200 on the remote controller 20 is toggled to the first gear (group one), the light units 10 in the first control group 1a corresponding to the gear can be controlled in groups as a whole. Furthermore, in some embodiments, the operations of group release (still in the network) and network unbinding of the light units 10 in the group may also be implemented in cooperation with other controls of the remote controller 20. For example, when the toggle switch 200 is toggled to the first gear (group one), the first control group 1a may be released if a predetermined action of the user on the remote controller is detected. The operation of network unbinding can be activated and carried out at the light unit 10, using mechanical means installed on the light unit 10, initializing the single light unit to be unbound from the network; it is also possible to perform the operations in groups from the remote controller 20, for example, the toggle switch 200 can be toggled to the first gear (group one), and all the light units 10 in the first control group 1a can be initialized completely through a predetermined action, so as to be unbound from the network.

Method flow (Single lamp control method)

With respect to the system in which grouping has been completed by the above initial setting method, the present embodiment also provides a control method of implementing single lamp control using the remote controller 20 capable of implementing grouping control. Referring to fig. 5, the left side of fig. 5 is the action performed by the remote controller 20 in the single lamp control method, and the right side of fig. 5 is the action performed by the light unit 10 in the single lamp control method.

In a normal case, since the infrared emitting unit 20IR has directivity, when the remote controller 20 is directed to the target light unit 10 attempting to perform single-lamp control, pressing the dimming key 208 can automatically activate the infrared mode, and directly adjust the dimming parameter of the light unit 10.

However, since some light units 10 are too close to each other, the infrared signal for single lamp control from the remote controller 20 can be reflected and received by a plurality of light units 10, or the infrared signal can be directly applied to a plurality of light units 10. The present embodiment also provides a single-lamp control method for these situations, the single-lamp control method including the steps of:

s08. signal detection step of activating the signal detection mode of the remote controller 20 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 between each light unit 10 and the remote controller 20, and if the signal strength of a specific bluetooth communication connection is higher than a threshold value or is the maximum value of the signal strength of each bluetooth communication connection, it is determined that the spatial position of the corresponding specific light unit is closest to the spatial position of the remote controller 20.

In this way, the control method provided by the present embodiment can use the remote controller 20 without a graphical user interface or with only a simple graphical user interface to implement group control and single lamp control for a complex lighting system. Moreover, the control of each light unit 10 and each control group in the system can be implemented by using the same remote controller 20, thereby greatly improving the integration level of the control equipment. Moreover, the operation process is simple and convenient, the pointing accuracy of single-lamp control is high, and a user-defined scene can be generated based on the single-lamp control result and can be directly called by the scene control 202 under the group control.

It should be noted that although the specific light unit controlled by the current view of the user is determined by the signal strength detection method in the present embodiment, the determination may be performed by any other suitable method in other embodiments of the present invention. For example, an infrared test signal may be emitted in response to operation of the remote control in an infrared mode,

the test signal does not contain a single lamp control command and is only used for testing the infrared signal receiving condition of each light unit 10. If the light unit 10 receives the infrared test signal, it may prompt the user to establish a communication link using its indicator light 110. The user can ensure the accuracy of the single-light control by adjusting the spatial position, the orientation of the remote controller, and the like to ensure that the indicator light 110 of the light unit only the target of which performs the single-light control is turned on, or can also ensure that the single-light control is only directed to a single target light unit 10 by selecting from the light units 10 with which the communication connection is established by using other controls.
