Description

Lighting system and control method thereof

Technical Field

Background

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.

In order to provide more complex human-computer interaction functions, a terminal application installed on an intelligent mobile terminal is generally used for controlling a system, and a graphical user interface provided by the terminal application can generate separate controls for different light units. 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.

Network

In this embodiment, the plurality of optical units 10 and the remote controller 20 are all 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 a 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.

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 first scene and the second scene may be factory preset, for example, constructed with 50% brightness and 100% brightness, respectively, 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.

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 in which 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 therebetween, which is shown by a solid line in the figure, and at least some light units 10 in different control groups also have bluetooth communication channels therebetween, which is shown by a dotted line in the figure.

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 single selection key 204, a feedback key 206, a dimming key 208, a bluetooth communication module 20BLE, a memory 20MEMO, and a processor 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; in the course of the selection of the light units 10 intended to carry out the single-lamp control, the establishment of the connection to be made in turn one by one in the light units 10 of the first control group 1a is indicated.

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 the present embodiment, the remote controller 20 has the single selection key 204 (single selection control module), and the remote controller 20 can establish communication connection with each light unit 10 in the same control group one by one in sequence in response to the operation of the single selection key 204 by the user.

Specifically, when the grouping control 200 is located in the shift position corresponding to the first control group 1a (the "group one" shift position), if a predetermined operation of the single selection key 204 by the user is detected (in this embodiment, the long press of the single selection key 204 exceeds 3s), the remote controller 20 broadcasts a trigger instruction of the single selection mode, and triggers each light unit 10 of the first control group 1a to enter the single selection mode. In the radio mode, the remote controller 20 will establish a connection with each light unit 10 in the first control group 1a one by one in turn, and the establishment of the connection is prompted by the indicator light 110 on the light unit 10.

The user may interact with the control system using the feedback keys 206 to confirm the goals of the single light control. Upon receiving the user feedback, the system will establish and maintain a communication connection between the user selected light unit 10 and the remote control 20 to ensure the persistence of the communication channel for implementing the single lamp control. For a detailed description of the corresponding functions of the above-described components, reference may be made to the subsequent method flow portion.

In addition, the remote controller 20 and the light unit 10 in the present embodiment are both provided with an indicator light, including the indicator light 210 of the remote controller 20 and the indicator light 110 of the light unit 10, the indicator light 110 is in communication connection with the main control chip 10C of the light unit 10, and the indicator light 210 is in communication connection with the main control chip 20C of the remote controller 20, so as to indicate the operating states of the remote controller 20 and the light unit 10, such as a single-light selection state, a pairing state, and the like, by using state changes such as flashing of the indicator lights 110 and 210. In some embodiments, the light unit 10 may also implement an indication function using its own state changes (e.g., state changes of blinking, extinguishing, and lighting, or adjustments of dimming parameters, such as changes in cool or warm tones). In other embodiments, the user may also be prompted with the sounding of a buzzer (not shown). The buzzer or the indicator light may be provided on the light unit 10 alone, on the remote control 20 alone, on the light unit 10 or the remote control 20 in a mutually paired manner, or in any other suitable position.

In this embodiment, the indicator 110 of the light unit 10 is in communication connection with the main control chip 10C, a connection indication module is stored in the memory 10MEMO of the main control chip 10C, and the processor can read and execute an instruction of the connection indication module to execute the following steps: the indicator lamp 110 blinks in response to the bluetooth communication module 10BLE of the light unit 10 establishing a communication connection with the bluetooth communication module 20BLE of the remote controller 20. The role that this connection indication module plays in the preparation step of the single light control will be detailed in the method flow section.

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 that the network establishment is successful, the process goes to the grouping step of 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 cancels the network establishment result, the power-on step of S01 is returned.

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, the initial setting is finished;

if the user cancels the grouping result, the process goes to S05.

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 and 6, 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, specifically, the control method includes the following steps:

in the ready state, the light unit 10 is in a normal operating state and the remote controller 20 is in an inoperative state. Take the grouping control 200 of the remote controller 20 being shifted to the gear corresponding to the first control group 1a (the "group one" gear), for example.

S07 single lamp control selection step, in response to the user' S long press of the single selection key 204, the remote controller 20 entering the single selection mode and the light units 10 in the same control group sequentially establish bluetooth communication connections one by one.

When a predetermined action by the user on the radio key 204 is detected, the remote control 20 and the individual light units 10 within the same control group (in this embodiment, the same control group is the first control group 1a since the grouping control 200 is located at the position corresponding to the first control group 1a) are triggered to enter the radio mode. In the radio mode, the remote controller 20 will establish a bluetooth communication connection with each light unit 10 in the first control group 1a one by one in turn. In the present embodiment, the operation for triggering entry into the radio mode is long pressing of the radio key for 3 seconds or more, but in other embodiments, other operations may be set as the trigger operation.

The order in which the bluetooth communication connections are established with the individual light units 10 can be adjusted to the actual situation. In some embodiments, the signal strength of the bluetooth communication connection between each light unit 10 and the remote controller 20 may be detected in the grouping step of S05, and the sequence of establishing the bluetooth communication connection between the remote controller 20 and the light units 10 in the step of S07 single-light control selection may be generated after sorting according to the magnitude of the signal strength. In some embodiments, the order of the bluetooth communication connections may also be established using the ordering of the MAC addresses.

S08 prompt step, in response to the corresponding current light unit 10 establishing connection with the remote controller 20, the indicator lamp 110 (i.e., the prompting portion) blinks (i.e., issues prompting information).

The indicator lamp 110 on the light unit 10 can prompt the user of the light unit 10 currently connected with the remote controller 20, and the user can determine whether the connected light unit 10 is the light unit 10 that the user intends to perform single-lamp control according to the prompt information, and switch between the light units 10 by using the interaction with the remote controller 20 until the target is selected. The selection process of the target is realized through the S09 selection step:

s09 selection step, by pressing the one-touch key 204 a plurality of times in succession, switching between a plurality of light units 10 within the same control group until the indicator light 110 of the light unit 10 to be subjected to the one-light control blinks.

In this embodiment, the light unit 10 to be controlled by one lamp is selected by switching in response, that is, if a single pressing operation of the one-selection key 204 by the user is detected, the communication connection with the current light unit 10 is disconnected, and the communication connection with the next light unit 10 is established according to a predetermined sequence. In another embodiment of the present invention, an automatic switching mode may be adopted, for example, a communication connection may be established with a certain light unit 10 when entering the radio mode, and the user may be notified of the connection state by the indicator lamp 110. Then, at preset intervals (e.g. 5 seconds), the communication connection with the current light unit 10 is automatically disconnected and a communication connection with the next light unit 10 is established in accordance with a predetermined sequence. If the user observes that the indicator lamp 110 of the light unit 10 to be subjected to single lamp control is blinking, the communication connection may be established directly via the feedback key 206. In yet another embodiment of the present invention, a pair of keys for the user to operate may be provided on the remote controller 20, wherein one of the keys may perform the sequential selection according to the predetermined sequence, and the other key may perform the reverse sequential selection opposite to the predetermined sequence, so as to improve the selection efficiency through the cooperation of the pair of keys. The predetermined sequence and the selection manner of the selection step are not limited, and may be implemented in any other suitable manner.

S10 feedback confirmation step of establishing or canceling the communication connection of the light unit 10 based on the detected operation result for the feedback key 206.

The feedback key 206 of the remote controller 20 is used for receiving the confirmation result of the selection of the light unit 10 by the user, and if the confirmation information is received, the communication connection between the current light unit 10 and the remote controller 20 is established, and the communication connection is maintained to receive the single lamp control instruction of the user; if the cancellation information is received, the process goes to S07 single-lamp control selection step, and communication connection is established with each light unit 10 in the control group one by one again.

S11 single lamp control step, which performs single lamp control on the single lamp control light unit 10TBC for which communication connection is established, and adjusts the dimming parameter of the single lamp control light unit 10TBC in accordance with a single lamp control command generated by the user through operation of the dimming key 208.

In the present embodiment, the remote controller 20 includes a light adjustment key 208, and can adjust the brightness of the light unit 10. In other embodiments of the present invention, the remote controller 20 may also have other dimming functions, for example, after establishing a communication control connection between the remote controller 20 and the current light unit (i.e. the single lamp control light unit 10TBC) associated with issuing the current prompt message, the remote controller 20 may adjust at least one or more of the color temperature, the time-delayed lamp elimination function, and the buzzer control function of the single lamp control light unit 10 TBC.

S12 setting and storing step, if receiving the confirmation information fed back by the user, changing the dimming parameter of the single lamp control light unit 10TBC and storing the changed dimming parameter in the memory 10MEMO or the memory 20MEMO, so as to modify the factory settings of the dimming parameters corresponding to the scene control 202 of the first scene, the second scene, and the like.

S13 scene generating step, based on the saved dimming parameters of the light units 10 in the same control group, creating a scene for the control group and saving it in the memory 20 MEMO.

In the present embodiment, a scene generation module (not shown) is stored in the memory of the remote controller, and the scene generation step S13 can be performed by reading and executing the scene generation module.

In some embodiments, a user may enter a scene setting mode by using a scene setting button (not shown) on the remote controller 20, after the light units that need to adjust the dimming parameter in the control group are all controlled by a single light, the final single light control results are determined, summarized and generated into a scene, and the scene is stored in the memory 20MEMO for the remote controller 20 to directly call by using the scene control 202 in the subsequent control process to reproduce the user-defined scene setting.

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, in the single-lamp control process, only a few light units 10 in the same group need to be selected, so that the user can conveniently complete the selection with fewer times. In addition, a prompt is given in the selection process, so that the selection intuitiveness and the selection speed are further improved. Moreover, a scene customized by a user can be generated based on the single-lamp control result, and the scene control 202 under the grouping control can be directly called.
