Description

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.

Wireless communication network

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

Infrared communication network

In the lighting system provided in this embodiment, the packet 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 as a node in the BLE Mesh network and the infrared receiving unit 10IR of the light unit 10 also 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 instructions to each light unit 10 by infrared communication.

The bluetooth communication module 20BLE of the remote control 20 is capable of establishing a communication connection with the bluetooth communication module 10BLE of each light unit 10 within the lighting system, and when the remote control 20 is used as a single light control, a user typically needs to select the light unit 10 from the plurality of light units 10 of the lighting system that he tries to perform the single light control. For lighting systems where the number of light units 10 is large and the remote control 20 does not have a graphical user interface (or only a simple graphical user interface), this selected procedure becomes extremely cumbersome.

In the existing lighting system, single-lamp control is usually implemented by using an infrared remote controller paired with the light units 10 one by one, and grouping control is performed by using an intelligent terminal for wifi interconnected light units 10, so that the control of the whole set of lighting system is required 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, infrared light is not completely controlled point-to-point, and can cover a certain range and be reflected by a wall surface or other objects, so that infrared signals will be received by a plurality of adjacent light units 10, which further causes a problem that single-lamp control is difficult to be accurately implemented.

In order to solve the above-described problem, in the illumination system provided in the present embodiment, 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, so that by configuring the infrared receiving units 10IR of the adjacent light units 10 on the different data channels to transmit data, even if the infrared signals emitted by the infrared emitting units 20IR are received by the adjacent light units 10, the adjacent light units are set on the different data channels, so that the adjacent light units cannot be decoded, thereby avoiding erroneous setting of adjacent lamps and improving accuracy of single-lamp control.

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

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 scenes may be factory preset, for example, may be constructed with different brightnesses, or may be set by the user himself, for example, the result of setting the 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.

The infrared receiving unit 10IR of the light unit 10 is in communication connection with the processor 10MCU, so that a single lamp control command of a user can be obtained, and the processor can set the dimming parameters of the light emitting component 106 by means of 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 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 of the light units (in this embodiment, the room is taken as a grouping condition), wherein 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, and at least some light units 10 in different control groups also have bluetooth communication channels.

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 grouping control 200, a scene control 202, a channel switching key 204, a feedback key 206, a dimming key 208, and an infrared transmitting unit 20IR, a bluetooth communication module 20BLE, a memory 20MEMO, and a processor 20MCU. Each key, bluetooth communication module 20BLE, memory 20MEMO are all connected with the input port of processor 20MCU, bluetooth communication module 20BLE, memory 20MEMO and infrared emission unit 20IR still are connected with the output port of 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; during the single lamp control, it is indicated that the single lamp control is to be performed 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 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 this embodiment, in response to the scene control being triggered, a scene control instruction is sent via the bluetooth communication module 20 BLE; in response to the dimming key 208 being activated, a single lamp control instruction is transmitted via the infrared transmitting unit 20IR. Because the same remote controller 20 has both the infrared emission unit 20IR and the Bluetooth communication module 20BLE, the infrared emission unit 20IR is utilized to send a single-lamp control instruction, and the Bluetooth communication module 20BLE is utilized to send a scene control instruction, the more preferable signal transmission mode can be configured for each set action when leaving the factory, and the user does not need to manually select again when implementing.

In this embodiment, the channel switch key 204 of the remote controller 20 can be used for a user to manually select a data channel currently used by the infrared transmitting 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 via the BLE Mesh network, for example, a signal strength detection function of the BLE Mesh network may be utilized, 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 receiving the data channel information, the remote controller 20 may automatically determine the data channel currently used by the infrared transmitting unit 20IR, or may send a prompt message by using the channel indicator lamp 212 to prompt the user to switch to the 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 press the corresponding dimming key 208, so that single lamp control can be accurately implemented on the target light unit 10, and the operation is simple and convenient and the pointing precision is higher.

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 successful networking using the feedback key 206, the process goes to the step S05 of grouping. 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 feedback key 206 cancels the networking result, the power-up step is returned to S01.

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 using the feedback key 206, then turning to S07 the channel allocation step;

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

S07 channel allocation step.

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

Method flow (grouping 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 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, 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 general, since the infrared emission unit 20IR has directivity, when the remote controller 20 is directed to the target light unit 10 attempting to perform the single-lamp control, the infrared mode can be automatically activated by pressing the dimming key 208, and the dimming parameters of the light unit 10 can be directly adjusted.

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

s08, in response to the long-pressing operation of the channel switch key 204 by the user, the signal detection mode of the remote controller 20 is activated. In the signal detection mode, the remote controller 20 can detect the signal intensity of the bluetooth communication connection established between each light unit 10 and the remote controller 20, and if the signal intensity of the specific bluetooth communication connection is higher than a threshold value or is the maximum value of the signal intensity of each bluetooth communication connection, determine that the spatial position of the corresponding specific light unit and the remote controller 20 is closest.

S09, a channel matching step, wherein a signal aiming at the specific light unit is broadcasted, the specific light unit is informed, and the information of the data channel currently used by the infrared receiving unit 10IR of the specific light unit is sent to the remote controller 20 through a BLE Mesh network. After receiving the data channel information, the remote controller 20 automatically matches the data channel adopted by the infrared emission unit 20IR with the data channel setting of the specific light unit, or sends out prompt information through the channel indicator lamp to prompt the user of the matched data channel setting.

And S10, single-lamp control is carried out on the specific light unit with the communication connection established, and the dimming parameter of the specific light unit is adjusted according to a single-lamp control instruction generated by a user through operation of the dimming key 208.

In the present embodiment, the remote controller 20 has a dimming key 208, and can adjust the luminance 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 a specific light unit, the remote controller 20 may be capable of adjusting at least one or more of a color temperature, a time delay dimming function, and a buzzer control function of the specific light unit.

And S11, setting and storing, namely, if the confirmation information fed back by the user through the feedback key 206 is received, changing the dimming parameter of the specific light unit, storing the changed dimming parameter in the memory 10MEMO or the memory 20MEMO, and further modifying factory settings of the dimming parameters corresponding to the scene controls 202 such as the scene one, the scene, and the like.

In some embodiments, the user may enter a scene setting mode by using a scene setting key (not shown) on the remote controller 20, after finishing single-lamp control on all the light units required to adjust the dimming parameters in the control group, determine, aggregate and generate a final single-lamp control result as a scene, and store the scene in the memory 20MEMO for the remote controller 20 to directly call by using the scene control 202 in a subsequent control process so as to reproduce the user-defined scene setting.

In the above manner, the control method provided in this embodiment can realize grouping control and single lamp control for a complex lighting system by using the remote controller 20 having no graphical user interface or only a simple graphical user interface. In addition, the control of each light unit 10 and each control group in the system can be implemented by using the same remote controller 20, so that the integration level of the control equipment is greatly improved. Furthermore, the operation process is simple and convenient, the pointing precision of single-lamp control is high, a scene customized by a user can be generated based on the single-lamp control result, and the scene control 202 for grouping control can be directly called.

Although the specific light unit controlled by the current view of the user is determined by the signal intensity 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 receiving condition of each light unit 10 for infrared signals. If the light unit 10 receives the infrared test signal, the indicator light 110 can be used to prompt the user for communication contact establishment. The user may ensure that only the indicator lamp 110 of the light unit whose target performs the single-lamp control is turned on by adjusting the spatial position, the remote control orientation, or the like, to ensure the accuracy of the single-lamp control, or may select from the light units 10 for which communication is established by using other controls, to ensure that the single-lamp control is directed to only a single target light unit 10.
