[0019] The configuration system is adapted to generate a trigger signal corresponding to the position information of each SDL module to be triggered based on the configuration data, and send the trigger signal to the corresponding SDL module to be triggered.

[0020] Optionally, there are multiple SDL modules;

[0021] The lighting system further comprises: a clock calibration system adapted to record the real time of each of the SDL modules and to synchronize and calibrate the real time of each of the SDL modules

[0022] Optionally, the configuration information includes time information of each SDL module to be triggered;

[0023] The configuration system is adapted to generate a trigger signal corresponding to the time information of each SDL module to be triggered based on the configuration data, and send the trigger signal to the corresponding SDL module to be triggered.

[0024] Optionally, the configuration system and each SDL module are communicatively connected via wired communication or wireless communication.

[0025] The embodiment of the present specification also provides a lighting control method, which is applied to the SDL module described in any of the above embodiments and is suitable for controlling the lighting status of several lighting modules, wherein the lighting control method includes:

[0026] In response to the trigger signal, selecting a lighting control mode corresponding to the current type of trigger signal from preset lighting control modes, and generating a pulse width modulation control signal corresponding to the lighting control mode;

[0027] In response to the pulse width modulation control signal, at least one of the lighting modules is selectively turned on, and based on the pulse width modulation control signal, a voltage parameter outputted to at least one of the lighting modules is adjusted to control the lighting state of at least one of the lighting modules.

[0028] By using the SDL module provided in this specification, the lighting status of several lighting modules can be controlled, wherein the control module can generate a corresponding pulse width modulation control signal in response to a trigger signal from the outside, and then when the driving module receives the pulse width modulation control signal output by the control module, at least one of the driving units is selected to be turned on. Since each driving unit is coupled to each lighting module in a one-to-one correspondence, when the driving unit is turned on, the lighting module coupled to the driving unit can be turned on, and the pulse width modulation control signal can adjust the electrical parameters output to the lighting module, so the lighting status of at least one of the lighting modules can be controlled. Since the lighting status of multiple lighting modules is centrally processed by the control module, the problem of increased system complexity caused by the use of multiple control modules can be avoided, and the difficulty and cost of system design can be reduced. In addition, each lighting module, control module and each driving unit in the present invention are arranged on the same substrate, which can further reduce the complexity of system design.

[0029] Furthermore, by integrating the lighting modules, the control module and the driving units on the same substrate to form an integrated structure, the overall volume of the SDL module can be further reduced.

[0030] Furthermore, the types of multiple lighting modules are not exactly the same, and thus the SDL module can turn on at least two different types of lighting modules and control the lighting states of at least two different types of lighting modules in one lighting control process, thereby being able to selectively adjust the state of the lighting light of each lighting module, and thus being able to output lighting light that meets various requirements and is suitable for various lighting scenes.

[0031] Furthermore, based on the type of trigger signal, a lighting control method corresponding to the current type of trigger signal can be selected from preset lighting control methods, and a pulse width modulation control signal corresponding to the lighting control method can be generated, thereby realizing a variety of lighting control schemes suitable for a variety of scenes; and by adopting the above method, the lighting state of the lighting module can be associated with the lighting control method, and by adopting the corresponding lighting control method, the lighting control process of the lighting module can be realized.

[0032] Furthermore, since the current conversion module can be coupled between the external power supply line and each driving unit, the current conversion module can convert the type of current provided by the external power supply line and provide an adapted current type for each driving unit to improve the stability of the SDL module.

[0033] Using the lighting system in the embodiment of this specification, the configuration system can generate a trigger signal based on the configuration data, and send the trigger signal to at least one SDL module on any lighting device, so that the SDL module can adjust the lighting state of at least one lighting device, thereby avoiding the problem of increased system complexity caused by the use of multiple SDL module blocks and reducing the difficulty and cost of system design.

[0034] Furthermore, since the configuration information includes the position information of each SDL module to be triggered, the configuration system can generate a trigger signal corresponding to the position information of each SDL module to be triggered based on the configuration data, and send the trigger signal to the corresponding SDL module to be triggered, so that the SDL module can turn on or off the corresponding lighting devices in sequence according to the set position information, so as to realize the coordinated control of each lighting device in space; and by changing the current output to the lighting device when the lighting device is in the on state, the lighting state of the lighting devices in different positions can be controlled, thereby providing different lighting needs.

[0045] As described in the background art, the control method used in the lighting system with multiple lighting modules in the prior art has problems such as complex system design and low integration.

[0046] In order to solve the above technical problems, the embodiment of the present specification provides an SDL module, which can control the lighting status of several lighting modules, wherein the control module can generate a corresponding pulse width modulation control signal in response to a trigger signal from the outside, and then when the driving module receives the pulse width modulation control signal output by the control module, at least one of the driving units is selected to be turned on. Since each driving unit is coupled to each lighting module in a one-to-one correspondence, when the driving unit is turned on, the lighting module coupled to the driving unit can be turned on, and the pulse width modulation control signal can adjust the electrical parameters output to the lighting module, so the lighting status of at least one of the lighting modules can be controlled. Since the lighting status of multiple lighting modules is centrally processed by the control module, the problem of increased system complexity caused by the use of multiple control modules can be avoided, and the difficulty and cost of system design can be reduced. In addition, each lighting module, control module and each driving unit in the present invention are arranged on the same substrate, which can further reduce the complexity of system design. Therefore, by using the SDL module provided in the embodiment of this specification, lighting control of multiple lighting modules can be achieved with lower design complexity and cost, so that the lighting equipment using it can achieve precise, personalized and automated lighting control, providing a more intelligent, comfortable and efficient lighting experience.

[0047] The "several" mentioned below refers to one or more; the "plurality" mentioned below refers to at least two or more.

[0048] In order to enable those skilled in the art to better understand and implement the embodiments of the present invention, the concepts, schemes, principles and advantages of the embodiments of this specification are described in detail below with reference to the drawings and through specific application examples.

[0049] First, the embodiment of this specification provides an SDL (Soft Defined Lighting, software defined lighting) module, such as Figure 1 and 2 As shown, the SDL module 100 can control the lighting status of several lighting modules, wherein the SDL module 100 may include: a control module 110 and a driving module 120, wherein:

[0050] The control module 110 is adapted to generate a corresponding pulse width modulation control signal in response to a trigger signal from the outside;

[0051] The driving module 120 may include a plurality of driving units, and the driving units and the lighting modules are coupled one by one, and is adapted to select at least one of the driving units to be turned on when receiving a pulse width modulation control signal output by the control module, and adjust the electrical parameters output by the driving unit to the lighting module based on the pulse width modulation control signal, so as to control the lighting state of at least one of the lighting modules;

[0052] The control module 110 and each driving unit can be arranged on the same substrate 101. For example, the control module 110 and each driving unit are integrated on the same substrate by SMT (Surface Mounted Technology) to form an integrated structure, which can reduce the overall volume of the SDL module. Compared with the device in the prior art that uses an independent single lamp controller to control the lighting module, the SDL module is lighter, smaller, and has simpler wiring.

[0053] Combination Figure 1 The driving module 120 may include a plurality of driving units, for example Figure 1 The driving units 121, 122, ..., 12n shown in FIG. 1 , correspondingly, the number of the lighting modules is also multiple, and can be the same as the number of the driving units, for example Figure 1 The lighting modules 100_1, 100_2, ..., 100_n are shown in FIG. 1 , wherein n is an integer greater than 1. The number of driving units and lighting modules can be determined according to actual needs and is not specifically limited here.

[0054] In a specific implementation, the driving unit may be coupled to the corresponding lighting module to control the lighting state of the lighting module. For example, the driving unit 121 may be coupled to the lighting module 100_1 to control the lighting state of the lighting module 100_1; the driving unit 122 may be coupled to the lighting module 100_2 to control the lighting state of the lighting module 100_2; ...; the driving unit 12n may be coupled to the lighting module 100_n to control the lighting state of the lighting module 100_n, wherein the lighting state of the lighting module may include at least one of an on state, an off state, brightness, color, and color temperature.

[0055] When the control module 110 responds to the trigger signal, it can output a corresponding pulse width modulation control signal to the driving module therein, so that at least one driving unit can be turned on, for example, the driving unit 121 can be turned on, and then the lighting state of the lighting module 100_1 coupled to the driving unit 121 can be controlled (for example, the lighting module 100_1 can be switched from an off state to an on state); and through the pulse width modulation control signal, the electrical parameters output by the driving unit to the lighting module can be adjusted, so the brightness, color temperature, etc. of the lighting module 100_1 can be adjusted.

[0056] Therefore, by coupling the driving units and lighting modules one by one, one control module can control the lighting status of all lighting modules, which can avoid the problem of increased system complexity caused by the use of multiple control modules, reduce the difficulty and cost of system design, and enable the lighting equipment using it to achieve precise, personalized and automated lighting control, providing a smarter, more comfortable and efficient lighting experience; and the control module and each driving unit in the present invention are arranged on the same substrate, which can further reduce the complexity of system design.

[0057] It should be noted that the structure of the SDL module shown in the above embodiment is only for illustrative purposes. For example, in the actual lighting control process, the number of driving units can be adjusted according to the number of lighting modules to achieve lighting control of all lighting modules; for example, for multiple lighting modules with the same operating characteristics, one driving unit can be used to control their lighting, wherein the driving unit can be coupled to the lighting module through a power line; for another example, the electrical parameters in the embodiments of this specification can be voltage parameters or current parameters. The embodiments of this specification do not limit this, as long as the SDL module can control the lighting status of several lighting modules.

[0058] In order to enable those skilled in the art to better understand and implement the embodiments of this specification, some specific examples are given below for the specific implementation of the control system in the embodiments of this specification.

[0059] Here, in some embodiments of the present specification, each lighting module, control module and each driving unit can be arranged on the same silicon wafer of the same substrate, or can be arranged on different silicon wafers of the same substrate, so that each lighting module, control module and each driving unit can be flexibly arranged in the SDL module without being restricted by the existing layout, and the overall volume of the SDL module can be reduced.

[0060] For example, Figure 1 and 2 As shown, each lighting module is an external module of the SDL module. In actual use, each lighting module needs to be separately connected to the driving module of the integrated structure composed of the control module 110 and the driving module 120.

[0061] Better, in order to further improve the integration of SDL modules, such as Figure 4 and Figure 5As shown, as another specific example, each lighting module (100_1, ..., 100_n, wherein n is a natural number greater than or equal to 2), a control module (110) and each driving unit (121, ..., 12n, wherein n is a natural number greater than or equal to 2) are integrated on the same substrate 101 by means of SMT to form an integrated structure, thereby being able to further reduce the overall volume of the SDL module 100; moreover, since the lighting module, the driving module and the control module together constitute an integrated structure, at this time, the lighting module is a built-in module of the SDL module, and the lighting module is pre-connected with the driving module, and in actual use, there is no need to separately connect the lighting module and the driving module.

[0062] In a specific implementation, the substrate may be an aluminum substrate or a ceramic substrate for heat dissipation.

[0063] In practical applications, the lighting module may be any element that can provide a light source.

[0064] For example, the lighting module may be one or more of a light emitting diode (LED), an organic light emitting diode (OLED) bulb, and a halogen light source. Since LED and OLED have the advantage of being digitally controllable, the lighting module in this specification may be an LED.

[0065] In a specific implementation, the types of multiple lighting modules may not be exactly the same (for example, the types of lighting module 100_1 and lighting module 100_2 are different, and the types of lighting module 100_1 and lighting module 100_n are the same), that is, the SDL module can control at least two different types of lighting modules, and then the SDL module can turn on at least two different types of lighting modules and control the lighting status of at least two different types of lighting modules in one lighting control process.

[0066] As a specific example, continue to refer to Figure 1 Assuming that the lighting module 100_1 is a cold light source and the lighting module 100_2 is a warm light source, the SDL module 100 can light up the lighting module 100_1 and the lighting module 100_2 at the same time, and continuously adjust the color temperature of the lighting light output by the lighting module 100_1 and the lighting module 100_2 by adjusting the electrical parameters output to the lighting module 100_1 and the lighting module 100_2, so as to achieve coordinated control of the cold light and the warm light, so that the color temperature of the lighting light output by the lighting module 100_1 and the lighting module 100_2 can be close to natural light.

[0067] As another specific example, the lighting module can also be a light source of Red, Green, Blue, Coolwhite, and Warm white colors. By matching the above-mentioned lighting modules of different colors, the lighting device has a colorful dimming function.

[0068] It can be understood that the lighting processes of different types of lighting modules in the above examples are only examples, and the embodiments of this specification do not limit this, as long as the SDL module can control the lighting processes of several lighting modules; in addition, the types of lighting modules in the embodiments of this specification can be the same, and the embodiments of this specification do not impose any restrictions on the types of lighting modules.

[0069] In a specific implementation, the control module can obtain the trigger signal from the outside in a variety of ways. For example, the trigger signal can be obtained through an external interface; for example, the trigger signal can be obtained by wireless transmission; for example, it can also be obtained from other storage units, and the embodiments of this specification do not limit this.

[0070] In some embodiments, the trigger signal can be obtained through the configuration system of the peripheral device through wireless communication. The specific description can be found in the subsequent description of the lighting device, which will not be elaborated here.

[0071] In a specific implementation, the types of the lighting modules may be different or based on different application requirements, the lighting control methods of the lighting modules may also be different.

[0072] In some embodiments of the present specification, the control module may select a lighting control method corresponding to the current type of trigger signal from preset lighting control methods based on the type of trigger signal, and generate a pulse width modulation control signal corresponding to the lighting control method to associate the lighting state of the lighting module with the lighting control method.

[0073] Specifically, a rule engine (RMS, i.e. Rule Manage System) can be pre-set in the SDL module. The rule engine means that the SDL module can respond to a variety of different types of trigger signals. It can also be understood that the control module can select a lighting rule corresponding to the current trigger signal from a pre-defined lighting method, and generate a corresponding pulse width modulation control signal for the selected lighting rule, so that the driving unit can dim the lighting module under the drive of the pulse width modulation control signal, so that the lighting parameters (brightness, color, color temperature, etc.) of the lighting module can be accurately adjusted through software to associate the lighting state of the lighting module with the lighting control method.

[0074] Therefore, by adopting the above scheme, based on the type of trigger signal, a variety of lighting control schemes can be implemented, which are suitable for a variety of scenarios; and the lighting state of the lighting module can be associated with the lighting control method. By adopting the corresponding lighting control method, the lighting control process of the lighting module can be realized.

[0075] In the specific implementation, based on actual needs, refer to Figure 3 The SDL module 100 in the embodiment of the present specification may further include: a current conversion module 130, coupled between the external power supply line 14A and each driving unit, suitable for converting the type of current provided by the power supply line 14A.

[0076] Combination Figure 3 The current conversion module 130 can be coupled between any driving unit and the power line 14A, for example, coupled between the driving unit 12n and the power line 14A, to provide an adaptive current type for the driving units 121, 122, ..., 12n to improve the stability of the SDL module.

[0077] As a specific example, the current conversion module can convert alternating current (AC) into direct current (DC). When the voltage type provided by the power supply module is alternating current, the current conversion module can convert the alternating current into direct current, and input the converted direct current into each drive unit for power supply.

[0078] In some other examples, the current conversion module can convert direct current (DC) into alternating current (AC), so as to convert the DC current provided by the power supply module into an AC current. The embodiments of this specification do not limit the conversion type of the current conversion module, as long as it can provide a suitable current for the drive unit.

[0079] Continue to refer to Figure 3 The power supply line 14A can also be a control module 110. When the control module 110 determines that the corresponding driving unit is working according to the trigger signal, it can adjust the voltage output by the driving unit to the lighting module through the pulse width modulation control signal, thereby adjusting the brightness parameters of the lighting module.

[0080] For example, if it is determined that the driving unit 121 is turned on according to the acquired trigger signal, the voltage value output to the lighting module 100_1 can be reduced, and the brightness of the lighting module 100_1 is reduced; for another example, if it is determined that the driving unit 122 is turned on according to the acquired trigger signal, the voltage value output to the lighting module 100_2 can be increased, and the brightness of the lighting module 100_2 is also enhanced.

[0081] By setting the power supply line, voltage can be provided to the control module and each driving unit, ensuring that the control module and each driving unit can work stably, thereby improving the stability of the SDL module.

[0082] In some other embodiments, the control module and each driving unit may have a built-in corresponding power supply, and different power supplies may be used to power the control module and each driving unit, respectively, without the need to provide an additional power supply module; or a power supply module provided in the SDL module may be used to power the control module and each driving unit at the same time, and the embodiments of this specification do not impose any restrictions on this.

[0083] Therefore, by using the SDL module in the above example, based on the acquired trigger signal, the lighting status of several lighting modules can be controlled, so that the lighting equipment using it can achieve precise, personalized and automated lighting control, providing a smarter, more comfortable and efficient lighting experience.

[0084] It can be understood that the above describes multiple embodiment schemes provided by the embodiments of this specification, and the various optional methods introduced in each embodiment scheme can be combined and cross-referenced with each other without conflict, thereby extending a variety of possible embodiment schemes, which can all be considered as embodiment schemes disclosed and open in this specification.

[0085] In a specific implementation, the SDL module of any of the above embodiments may be applied to a corresponding lighting system to control the lighting state.

[0086] Reference Figure 6 The structural diagram of a lighting system in an embodiment of this specification is shown in FIG. Figure 6 As shown, in some embodiments of the present specification, the lighting system 200 may include: a plurality of lighting devices and a configuration system 220, wherein:

[0087] Each lighting device is configured with at least one SDL module according to any of the aforementioned embodiments;

[0088] The configuration system 220 is coupled to the SDL module, and is adapted to generate a trigger signal based on the configuration data, and send the trigger signal to at least one SDL module on any lighting device.

[0089] For the convenience of explanation, an illumination device 210 in the illumination system is taken as an example, and the illumination device 210 has multiple SDL modules. For the description of other illumination devices, refer to the content of the illumination device 210 .

[0090] Combination Figure 6 , the lighting device 210 may include multiple SDL modules, such as Figure 6, 210_1 , 210_2 , . . . , 210_m are shown in FIG. 2 , where m is an integer greater than 1, and the SDL modules 210_1 , 210_2 , . . . , 210_m are all coupled to the configuration system 220 .

[0091] It is understandable that the number of SDL modules can be determined according to actual needs and is not specifically limited here.

[0092] Using the lighting system 200 in the embodiment of the present specification, the configuration system 220 can generate a trigger signal based on the configuration data, and send the trigger signal to at least one SDL module on any lighting device, such as the SDL module 210_1, so that the SDL module 210_1 can adjust the lighting state of the lighting device 210, thereby avoiding the problem of increased system complexity caused by the use of multiple SDL module blocks, reducing the difficulty and cost of system design, and being able to control the lighting state of the lighting device 210, for example, changing the brightness and color temperature of the lighting device 210, or switching the on and off state of the lighting device 210, thereby being able to provide appropriate lighting light, achieve precise, personalized and automated lighting control, and provide a smarter, more comfortable and efficient lighting experience.

[0093] In the process of controlling the lighting status of multiple lighting devices, the SDL module, in addition to outputting pulse width modulation control signals, also generates a large amount of intermediate data. These intermediate data and pulse width modulation control signals can represent the real-time operating status of the currently controlled lighting devices. Therefore, these data can be recorded to improve the continuity and integrity of the lighting control process of the SDL module; on the other hand, it can optimize the lighting control process of the SDL module, improve control stability, and by configuring different trigger signals, it can achieve multiple controls of lighting devices.

[0094] In a specific implementation, the configuration system can configure the lighting control method of each lighting module (for example, lighting up or extinguishing the corresponding lighting modules in sequence, or turning on or off the corresponding lighting modules in a time-sharing manner), the lighting duration of each lighting module, the lighting intensity of each lighting module, etc. based on the configuration data.

[0095] Specifically, the configuration system usually controls the output of different trigger signals to multiple SDL modules (e.g. Figure 6 In the example of FIG. 1 , the trigger signal includes the position information of the m SDL modules, and thus a sequential lighting mode can be defined. In this lighting mode, the first to the nth SDL modules can receive the trigger signal in sequence and light up the corresponding lighting devices. If the lighting mode is to be triggered, a trigger signal generated based on the position information of the m SDL modules can be sent to the SDL module to light up different lighting devices in sequence.

[0096] As a specific example, there are multiple SDL modules, and the configuration information includes the location information of each SDL module to be triggered, so that the configuration system can be suitable for generating a trigger signal corresponding to the location information of each SDL module to be triggered based on the configuration data, and sending the trigger signal to the corresponding SDL module to be triggered.

[0097] And by adopting the above method, the lighting state of the lighting equipment can be selectively controlled according to the acquired data. For example, for places with a large number of people or densely populated areas, more lighting equipment can be controlled to light up in sequence; while for places with fewer people or sparsely populated areas, fewer lighting equipment can be controlled to light up in sequence; for example, for darker areas, more lighting equipment can be controlled to light up in sequence or the voltage output to the lighting equipment can be increased to enhance the brightness of the lighting equipment; while for relatively bright areas, fewer lighting equipment can be controlled to light up in sequence or the voltage output to the lighting equipment can be reduced to reduce the brightness of the lighting equipment.

[0098] By adopting the above-mentioned lighting control method, based on the position information of the SDL module, the coordinated control of various lighting devices in space can be achieved, and by changing the current output to the lighting device when the lighting device is in the on state, the lighting state of lighting devices in different positions can be controlled, thereby providing different lighting needs.

[0099] It can be understood that the above-described method of controlling the lighting status of the lighting device according to the position information of the SDL module is only an example. For example, the lighting status of the lighting device at a specific location can also be controlled. The embodiments of this specification do not limit this, as long as the lighting status of the lighting device can be controlled.

[0100] In a specific implementation, there are multiple SDL modules, and the working hours of multiple SDL modules may be different. Based on this, the lighting system in the embodiment of this specification may also include: a clock calibration system, suitable for recording the real-time time of each SDL module and synchronizing and calibrating the real-time time of each SDL module.

[0101] Specifically, by setting up a clock calibration system, all communication nodes in the SDL module in the communication network can achieve time synchronization through the Network Time Protocol (NTP), and all communication nodes can achieve real-time data transmission through the Time-Sensitive Networking (TSN), so that each communication node follows the same rules when processing and forwarding communication data packets, as well as the same rules when selecting communication paths and reserving bandwidth and time slots.

[0102] In this case, the configuration information includes the time information of each SDL module to be triggered, and the configuration system can be adapted to generate a trigger signal corresponding to the time information of each SDL module to be triggered based on the configuration data, and send the trigger signal to the corresponding SDL module to be triggered.

[0103] Specifically, since the time information of multiple SDL modules is synchronized, a time-sharing lighting method can be defined. In this lighting method, the lighting equipment is controlled to be turned on or off at different time points, or the lighting parameters of the lighting equipment are adjusted at different time points to change the current lighting state.

[0104] For example, when it turns from day to night, each lighting device can be lit in turn according to the preset time to gradually illuminate the streets or other areas that need lighting, or the electrical parameters (such as current) output to the lighting devices can be increased in turn at different time points to enhance the brightness of each lighting device; for example, when it enters late at night, only some lighting devices can be lit, for example, lighting devices in underground parking lots, monitoring areas, and road areas are lit; for another example, when it turns from night to day, each lighting device can be turned off in turn according to the preset time, or the electrical parameters output to the lighting devices can be reduced in turn at different time points to reduce the brightness of each lighting device.

[0105] Therefore, by adopting the above-mentioned lighting control method, based on the time information of each SDL module, the coordinated control of each SDL module in terms of time can be achieved; and by changing the electrical parameters output to the lighting device when the lighting device is in the on state, the lighting state of the lighting device can be controlled at different or specific time points, thereby providing different lighting needs.

[0106] It can be understood that the above-described method of controlling the lighting status of the lighting equipment according to the time information of each SDL module is only an example. For example, the lighting status of the lighting equipment at a specific time point can also be controlled, such as turning off all lighting equipment at 7 o'clock in the morning. The embodiments of this specification do not limit this, as long as the lighting status of the lighting equipment can be controlled at different time points.

[0107] In some embodiments of the present specification, a clock chip (i.e., RTC, Rael-Time Clock) can be set inside each SDL. The clock chip can record the real-time time of the SDL module, provide conditions for time calibration between multiple SDL modules, and make it possible to control the lighting status of the lighting device through the SDL module at a specific time point.

[0108] In some embodiments of the present specification, the configuration system may output a trigger signal to the SDL module in a variety of ways, for example, inputting configuration data to the SDL module through an external interface; for example, inputting a trigger signal to the SDL module through wireless communication. The embodiments of the present specification do not limit the communication method between the configuration system and the SDL module, and they may be connected through wired communication or wireless communication.

[0109] In actual application, at least one of the following methods can be used to achieve communication between the configuration system and the SDL module: Bluetooth; WiFi; ZigBee; PLC (PowerLine Communication); 485; DALI; DMX512; KNX; BLE.

[0110] In some embodiments of the present specification, since power carrier communication can realize long-distance transmission of trigger signals with the help of power lines, the configuration system and the SDL module can realize signal transmission through power carrier communication, and by adopting this communication method, the configuration system and the SDL module can be respectively set at locations far away to realize remote control.

[0111] When the configuration system and the SDL module adopt power line carrier communication to realize signal transmission, the configuration system may include an input port (e.g., a current input port), a central coordinator (CCO), a power line carrier communication (PLC) module, and an output port (e.g., a current output port), wherein the current input port is connected to an external power supply and draws power, the central coordinator may be connected to the power line carrier communication module, the current input port is connected to the power line carrier communication module and the output port, and the output port is connected to the lighting system and the SDL module via a power line.

[0112] To facilitate understanding of the working process of the lighting system in the embodiments of this specification, a detailed description is given below through specific examples in conjunction with the accompanying drawings.

[0113] See also Figure 7 The structural diagram of the lighting system in a specific application scenario in the embodiment of this specification is shown in FIG. Figure 7 As shown, the lighting device system includes three lighting devices and a configuration system connected to the power lines of each lighting system, wherein the three lighting devices have the same structure and can include a pole body and multiple lighting modules arranged on the pole body, and at least one SDL module arranged inside the pole body.

[0114] Specifically, Figure 7As shown, the lighting device may include a rod body 20 and LEDs 21, 22 and 23 disposed on the rod body 20, wherein the SDL module is installed inside the rod body 20 and connected to the LEDs 21, 22 and 23 via power lines. It is understood that the structures of other lighting devices can refer to the above description and will not be expanded here.

[0115] Figure 7 The working principle of the lighting system is as follows: when the input port outputs AC power to the power line through the output port, the central coordinator 11 can directly generate control trigger instructions for each pole body (including on-off control, or dimming control), or directly receive control trigger instructions sent by an external control device through a gateway. The communication module 12 (specifically, it can be a power line carrier communication module) can encode the control trigger instruction into a trigger signal, and transmit it to the corresponding pole body through the output port and the power line in turn. For example, the trigger signal Tr1 can be transmitted to the pole body 20, the trigger signal Tr2 can be transmitted to the pole body 30, and the trigger signal Tr3 can be transmitted to the pole body 40.

[0116] The SDL module (specifically, it can be a control module) corresponding to each pole body receives the control trigger signal. The communication control module selects a dimming rule corresponding to the current control trigger signal from a predefined dimming rule library based on the rule engine under the drive of the control trigger signal, and generates a corresponding pulse width modulation control signal for the selected dimming rule, and inputs the control instruction corresponding to the pulse width modulation control signal to the driving module, so that the driving module performs dimming control on the LED under the drive of the pulse width modulation control signal.

[0117] For example, during a lighting control process, the LED 21 may be turned on, and parameters such as the brightness and color temperature of the LED 21 may be adjusted.

[0118] In some embodiments, multiple SDL modules can be set on a pole, and the rule engine of each SDL module can define some lighting rules associated with the individual control or combined control of multiple LED lights on a single pole, and can also define a group composed of multiple light poles for spatiotemporal coordinated control (i.e., in terms of space and time). This integrated design makes the lighting system more flexible and customizable to meet the control needs of different users and scenarios.

[0119] For example, in one lighting control process, LED 21 and LED 32 may be lit at the same time, and parameters such as the brightness and color temperature of LED 21 and LED 32 may be adjusted.

[0120] It is understandable that the lighting control process of each LED can be flexibly controlled according to actual needs, and the embodiments of this specification do not limit this, as long as the lighting equipment can achieve accurate, personalized and automated lighting control to provide a smarter, more comfortable and efficient lighting experience.

[0121] In actual working process, when lighting equipment runs for a long time, it may be affected by various factors and its operating state (such as luminous power) may change or even flicker until it cannot be used.

[0122] Based on this, the lighting system in the embodiment of this specification may also include a status acquisition system, to which each lighting device is coupled, suitable for acquiring the operating status of each lighting device, and outputting a warning signal when it is determined that the operating status of the lighting device is abnormal.

[0123] Specifically, the status acquisition system can automatically collect the operating status of each lighting device and generate a characteristic signal corresponding to the operating status. Based on the characteristic signal, the operating status of the lighting device can be judged and an early warning signal can be output.

[0124] In a specific implementation, one characteristic signal generally corresponds to one status judgment result. In order to more accurately judge the operating status of each lighting device, in some embodiments of the present specification, the status acquisition system can collect multiple characteristic signals of the lighting device or collect multiple characteristic signals of the lighting device within a certain time period, and judge the status judgment result of each lighting device in turn according to the preset abnormal judgment conditions, and when the number of status judgment results reaches a preset threshold, output a warning signal to remind maintenance personnel to perform maintenance.

[0125] The size of the preset threshold can be set according to the importance of the abnormality of the lighting device. For example, for some abnormalities with a higher degree of importance (for example, the lighting device cannot work), the corresponding preset threshold can be smaller, such as 1, that is, as soon as the lighting module has an abnormality, it will immediately output a warning signal; for some abnormalities with a lower degree of importance (for example, low luminous power), the corresponding preset threshold can be larger, and this specification does not make specific restrictions on this.

[0126] Therefore, by adopting a lighting system with a status acquisition system, by collecting the operating status of each lighting device and outputting a warning signal when it is determined that the operating status of the lighting device is abnormal, it is possible to ensure the stable and safe operation of the lighting system. By setting a preset threshold, it is possible to avoid misjudgment of the operating status of the lighting device due to a single accidental factor, thereby improving the robustness of the lighting system.

[0127] Accordingly, the embodiments of the present specification also provide a lighting control method, which is described in detail below with reference to the accompanying drawings and through examples.

[0128] It should be noted that the lighting control method described below can be considered as a control method adopted by the SDL module provided in the embodiment of this specification; the content of the lighting control method described below can be referenced in correspondence with the content of the SDL module described above.

[0129] Reference Figure 5 The flowchart of a lighting control method in the embodiment of the present specification is shown, and the lighting control method is applied to the SDL system of any of the above embodiments, and is suitable for controlling the lighting status of several lighting modules, such as Figure 8 As shown, the lighting state of the lighting module can be controlled by the following steps:

[0130] S11, in response to a trigger signal, selecting a lighting control mode corresponding to the current type of trigger signal from preset lighting control modes, and generating a pulse width modulation control signal corresponding to the lighting control mode.

[0131] S12, in response to the pulse width modulation control signal, selectively turn on at least one of the lighting modules, and based on the pulse width modulation control signal, adjust the voltage parameter outputted by at least one of the lighting modules to control the lighting state of at least one of the lighting modules.

[0132] By adopting the above-mentioned lighting control method, the lighting status of multiple lighting modules can be centrally processed, which can avoid the problem of increased system complexity caused by using multiple control modules to process separately, reduce the difficulty and cost of system design, and enable the lighting equipment using it to achieve precise, personalized and automated lighting control, providing a more intelligent, comfortable and efficient lighting experience design complexity.

[0133] Although the embodiments of this specification are disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, so the protection scope of the present invention shall be subject to the scope defined by the claims.
