Description

Lighting system and control method for lighting system

Technical Field

The present invention relates to the field of lighting, and more particularly to the field of lighting control technology.

Background

With the advent of the intelligent industry and the internet of things, more and more electric products are brought into the internet of things for intelligent unified management. Similar changes also occur in the lighting industry, and along with popularization of the internet of things technology, communication modules are also installed or connected on more and more lighting apparatuses so as to adapt to the needs of intellectualization and interconnection.

At the same time, for indoor or outdoor lighting, the user is no longer satisfied with the simple need to obtain sufficient illuminance with a single luminaire, but is increasingly focusing on the decorative function of the lighting itself. By utilizing the matching 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 lighting state of the light sources, such as shutters, lampshades and baffles), various complicated and attractive lighting scenes can be combined, and the matching of the technology and the art is promoted in the field of commercial lighting and household lighting.

While group control can facilitate the user in constructing and reproducing complex and aesthetically pleasing lighting scenes, single light control is still not disposable in most cases from the standpoint of operational and control flexibility. For the above reasons, as the control system needs to meet both single light control and group control requirements, the number of selectable or tunable items it needs to interact with the user becomes more and more, and the implemented system becomes more and more complex.

In order to provide more complex man-machine interaction functions, the system is usually controlled by using a terminal application installed on the intelligent mobile terminal, and a graphical user interface provided by the terminal application can generate separate controls for different light units. The user can click on a control to implement single-lamp control on the corresponding light units, or 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 control of the lighting system is implemented by using the smart mobile terminal, on the one hand, the cost of manufacturing software, a graphic user interface and the like is high, and on the other hand, some countries and regions with insufficient popularity of the smart mobile phone and some people with specific usage habits (such as the elderly) do not tend to use the smart mobile terminal for installation and control, so the terminal application still faces a plurality of difficulties in actual popularization.

Detailed Description

Hereinafter, preferred embodiments of the present invention will be described generally with reference to the accompanying drawings. The embodiments of the present invention are not limited to the following embodiments, and various embodiments within the scope of the technical idea of the present invention can be employed.

The present embodiment first provides an illumination system, and the illumination system provided by the present embodiment is described below with reference to fig. 1 from various aspects.

Network system

In this embodiment, bluetooth Mesh (Bluetooth Mesh) is used for connection between the plurality of optical units 10 and the remote controller 20, and further, the Bluetooth Mesh in this embodiment is a network topology constructed based on a low power version of Bluetooth standard protocol of 4.0 or more, that is, a Bluetooth low energy Mesh (BLE Mesh, bluetooth Low Energy Mesh).

Each of the optical units 10 and the remote controller 20 has bluetooth communication modules (10 BLE and 20 BLE) that are one node in the bluetooth low energy mesh network, and the nodes in the bluetooth low energy mesh network can be mutually transmitted 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 broadcast data by means of network connection between the optical units 10, and send control signals to the optical units 10 outside the signal sending working distance of the remote controller 20 to implement control.

In the conventional lamp control mode, the lamps in the current room need to be turned off and left before the night rest, if no other light source irradiates in the room, the user needs to act in a dark environment in the period from the time of turning off the lamps in the current room to the time of turning on the lamps in another room, and the user experience is poor. By the above mesh network connection, the user can choose not to turn off the lamp in the current room, and after moving to another room, the carried remote controller 20 is used to turn off the lamp in the original room, so that no action in dark environment is needed, and the use requirement of the lamp in the initial design layout process is reduced.

Light unit

In some embodiments, the light unit 10 may be one or a combination of several selected from incandescent, decorative incandescent, enclosed light, infrared, halogen, LED, fluorescent, sodium, xenon, ceiling, chandelier, ceiling, recessed ceiling, wall-mounted, wall-hung, desk, floor, street, garden, door, flashlight, pocket, lantern, searchlight, spotlight, or any other suitable controllable light source, or any combination of any suitable uncontrollable light source described above and accessories capable of changing the illumination state of the light source, such as controllable blinds, lampshades, baffles, etc., or may be a controllable module or assembly of any one or more of the above.

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 perform dimming control on a light emitting module 106 of the LED lamp via a driving power supply 104. In this embodiment, the first and second scenes may be factory preset, for example, may be constructed with 50% brightness and 100% brightness, respectively, or may be set by the user himself, for example, the result of setting a single lamp may be fixed and stored.

In this embodiment, the LED lamp (light unit 10) further has 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 integrated with the PWM dimming circuit 102 in the same main control chip 10C, so that the switching and dimming parameters of the light unit 10 can be adjusted based on the control instruction obtained by the bluetooth communication module 10 BLE. Integrating the PWM dimming circuit 102 with the bluetooth communication module 10BLE can effectively reduce cost. In addition, in order to make the integrated bluetooth communication module 10BLE and the PWM dimming circuit 102 be adapted to different types of light units 10, multiple types of chips may be used for adapting respectively, and a general bluetooth module may also be used for adapting to different peripheral circuits, so as to reduce the cost of adapting to different types of light units.

In some embodiments, for some light units 10 whose light performance is controlled at least partially by the accessory, the bluetooth communication module 10BLE may also be communicatively connected to the control portion of the accessory to control the working state of the accessory, for example, to the driving component of the lampshade to adjust the opening and closing degree of the lampshade.

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

In addition, the main control chip 10C of the light unit 10 in the present embodiment is integrated with or connected to the memory 10MEMO, and the main control chip 10C can acquire the switching state and the dimming parameter of the light unit 10, and store the acquired operation data about the switching state and the dimming parameter in the memory 10 MEMO. In some embodiments, the memory 10MEMO may also be set in the main control chip 10C of only part of the light units 10 in the lighting system, where the one or more main control chips 10C provided with the memory 10MEMO can obtain 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 light 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 read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), FLASH memory (FLASH), or any other device capable of storing program instructions or data with or without application of 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 be used to implement the storage. The memory 10MEMO may be implemented using a single memory module or multiple memory modules, and may also be configured as a cloud memory separate from the light unit 10 or remote control 20.

Grouping

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

In other embodiments of the invention, the lighting 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 actual usage logic (for example, a group of spot lights which are far from each other but illuminate the same area), or its own characteristics (for example, according to the light color and intensity), or the like. Furthermore, although in the present embodiment the same light unit 10 may be divided into a single control group in the lighting system, in some embodiments of the present invention the same light unit may also be used by different control groups; the number of control groups is not limited to two in the present embodiment, and three or more may be provided according to actual needs.

Remote controller

Referring to fig. 3, the remote controller 20 used in the lighting system of the present embodiment includes a group control 200, a scene control 202, a radio key 204, a feedback key 206, a dimming key 208, and a bluetooth communication module 20BLE, a memory 20MEMO, and a processor 20MCU.

The grouping control 200 is a toggle switch, and the plurality of light units 10 in the system can be respectively controlled by two control groups, and correspondingly, the two control groups are switched by adopting a two-position toggle switch. In other embodiments of the present invention, more than three toggle switches may be used, such as four toggle switches to effect switching 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 group control 200 is in the position of the first control group 1 a: in the grouping process, indicating that the grouping action is to distribute the optical units 10 to be grouped into the first control group 1 a; during the control, indicating that the present control action is to be performed for the light units 10 in the first control group 1 a; in the releasing or initializing grouping process, it is instructed that grouping of the light units 10 in the first control group 1a is to be released or that the light units 10 in the first control group 1a are to be initially set; in preparation for the selection of the light units 10 to perform the single-light control, the establishment of connections to be made one by one in sequence among 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 button and two preset scene buttons, which can be pressed by a user to turn off (light off) all light units in the corresponding control group, 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 as desired for the control function. In this embodiment, the user may use a single-lamp adjustment manner, after adjusting the dimming parameters of the light units 10 in the control group to a satisfactory state, save the dimming parameters of the light units 10 in the remote controller 20 or the memory 10MEMO or 20MEMO of the light units 10, so as to modify the factory settings of the scene control 202 such as the scene one and the scene one, and see the following method flow part for specific system configuration and operation manner.

In some embodiments of the present invention, the remote controllers 20 may also have a plurality of remote controllers and each may be used as a node in the BLE Mesh network, the information set and stored between different remote controllers 20 may be kept synchronous, and the user may implement control using the remote controller 20 corresponding to each room.

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

Specifically, when the grouping control 200 is located in the gear corresponding to the first control group 1a (the "group one" gear), if a predetermined operation of the single selection key 204 by the user is detected (in this embodiment, the single selection key 204 is pressed for longer than 3 s), the remote controller 20 broadcasts a trigger instruction of the single selection mode, and the light units 10 of the first control group 1a are triggered to enter the single selection mode. In the single-choice mode, the remote control 20 will establish connections with the individual light units 10 in the first control group 1a one by one in sequence, 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 key 206 to confirm the goal of single light control. Upon receiving 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 viability of the communication channel over which the single light control is implemented. Specific descriptions of corresponding functions of the above components may be found in the subsequent flow part of the method.

In addition, in the present embodiment, the remote controller 20 and the light unit 10 are provided with indicator lamps, including the indicator lamp 210 of the remote controller 20 and the indicator lamp 110 of the light unit 10, the indicator lamp 110 is in communication connection with the main control chip 10C of the light unit 10, and the indicator lamp 210 is in communication connection with the main control chip 20C of the remote controller 20, so that the operating states of the remote controller 20 and the light unit 10, such as a single lamp selection state, a pairing state, and the like, are indicated by using state changes such as blinking of the indicator lamps 110, 210. In some embodiments, the light unit 10 may also implement an indication function using its own state change (e.g., a state change of blinking, extinguishing, and lighting, or adjustment of a dimming parameter, such as a change in cool-warm tone). In other embodiments, the sounding of a buzzer (not shown) may also be employed to alert the user. The buzzer or the indicator lamp may be separately provided on the light unit 10, may be separately provided on the remote controller 20, may be provided on the light unit 10 or the remote controller 20 in a mutually paired manner, or may be provided at any other suitable position.

In this embodiment, the indicator lamp 110 of the optical unit 10 is in communication connection with the main control chip 10C, the connection indication module is stored in the memory 10MEMO of the main control chip 10C, and the processor can read and execute the instruction of the connection indication module to execute the following steps: the indicator light 110 flashes 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 control 20. The function that the connection indicating module plays in the preparation step of the single lamp control will be described in detail 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 this embodiment specifically includes the following steps:

and S01, powering up.

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

S02, initializing

Each light unit 10 and remote control 20 reads the initial data in the firmware and initializes the light unit settings.

S03, networking

Each light unit 10 and the remote controller 20 enter a pairing waiting mode, in which the bluetooth communication modules 10BLE of the light units 10 communicate with each other using a short-range broadcast mode, in which signals smaller than the signal strength threshold are ignored by setting the signal strength threshold, so as to reduce the possibility that the light units 10 to be paired are wrongly bound by the networks of other lighting systems.

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

For example, an operation of repeatedly opening and closing the mechanical switch 108 (or repeatedly switching of the switch state is detected) for a certain period of time may be used as a trigger operation for initializing the optical unit 10, and in response to detecting the trigger operation, the optical unit 10 may be forcedly initialized to a factory state and removed from the BLE Mesh network after pairing is completed. In some embodiments, the light units 10 within different rooms or areas are added to the same network in response to separate acknowledgements from those different rooms or areas.

S04, confirming a networking result.

The user can learn the networking result through the indication of the light unit 10 and the indication lamps 110, 210 on the remote control 20. If 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 inform the user of the networking result by means of flashing behavior, turning on and off, flashing frequency, breathing lamp change and the like.

If the user confirms that the network construction is successful, the step of grouping is switched to S05. In this embodiment, after the network is established successfully, the indicator lamp 110 is turned on after flashing once, and is used as a predetermined prompting mode.

If the user cancels the networking result, returning to the step S01 of powering on.

S05, grouping.

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

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

S06 confirms the grouping result.

If the user confirms the grouping result, the initial setting is completed;

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

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 plurality of light units 10 in the first control group 1a corresponding to the gear may be group-controlled as a whole. In addition, in some embodiments, the operations of group de-grouping (still in the network) and network de-binding of the light units 10 within the group may also be implemented in conjunction with other controls of the remote control 20. For example, when the toggle switch 200 is toggled to the first gear (group one), if a predetermined action of the user on the remote controller is detected, the first control group 1a may be released. The network unbinding operation may be activated and implemented at the light unit 10 using mechanical means mounted on the light unit 10, initializing individual light units to unbinding from the network; it is also possible to perform the operation from the remote control 20 in groups, for example, the toggle switch 200 may be toggled to the first gear (group one), and all the light units 10 in the first control group 1a are initialized by a predetermined action, and unbind from the network.

Method flow (Single)Lamp control method

As for the system in which grouping has been completed by the above initial setting method, the present embodiment also provides a control method for implementing single-lamp control by 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 steps of:

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

And S07, single-lamp control selection, namely, in response to the operation of long-time pressing of the single-selection key 204 by a user, sequentially establishing Bluetooth communication connection between the remote controller 20 entering the single-selection mode and each light unit 10 in the same control group one by one.

When a predetermined action of the user on the single selection key 204 is detected, the remote control 20 and the same control group (in this embodiment, the same control group is the first control group 1a because the grouping control 200 is located at a position corresponding to the first control group 1 a) are triggered, and each light unit 10 in the same control group enters the single selection mode. In the single-choice mode, the remote control 20 will establish bluetooth communication connections with the individual light units 10 in the first control group 1a one by one in sequence. In the present embodiment, the operation to trigger the entry into the single-selection mode is a long press of the single-selection key for 3 seconds or more, and in other embodiments, other operations may be set as the trigger operation.

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

S08, in response to the corresponding current light unit 10 establishing a connection with the remote controller 20, the indicator light 110 (i.e., the prompting portion) blinks (i.e., sends out a prompting message).

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

s09 selecting step of switching between the plurality of light units 10 in the same control group by continuously pressing the single key 204 a plurality of times until the indicator lamp 110 of the light unit 10 to be subjected to the single lamp control blinks.

In this embodiment, the selection of the light unit 10 to be subjected to the single-light control adopts a response switching manner, that is, if a single pressing operation of the single-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 manner may be adopted, for example, a communication connection may be established with a certain light unit 10 when entering the radio mode, and the indication lamp 110 informs the user of the connection state. Then, at every preset time (for example, 5 seconds), the communication connection with the current light unit 10 is automatically disconnected, and the communication connection with the next light unit 10 is established in a predetermined order. If the user observes that the indicator light 110 of the light unit 10 to be subjected to the single-light control blinks, the communication connection can be established directly via the feedback key 206. In still another embodiment of the present invention, a pair of keys for user operation may be provided on the remote controller 20, wherein one key may be selected in a predetermined order, and the other key may be selected in a reverse order opposite to the predetermined order, so as to improve the selection efficiency by cooperation of the pair of keys. The above-mentioned selection method of the predetermined sequence and the selection steps is not limited, and may be implemented in any other suitable manner.
