[0046] To make the objectives, technical solutions, and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is apparent that the embodiments described are only some, not all, of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0047] An embodiment of the present invention provides a lighting system and device that uses a tree-shaped storage structure to store and call special effect lighting arrays and various lighting parameters in a tree-shaped structure in real time, providing a special effect implementation solution suitable for photographic scenes, simple stage scenes, and simple movie shooting scenes.

[0048] like Figure 2 FIG. 1 is a block diagram of a lighting system according to an embodiment of the present invention, comprising:

[0049] lighting equipment 201;

[0050] This embodiment is applicable to stage scenes, film and television drama shooting scenes, photography scenes, etc., so the lighting equipment includes all lighting lamps suitable for the above scenes.

[0051] The following description will mainly take a photography scene as an example, so the lighting equipment is preferably a photography light.

[0052] The microcontroller 202 is used to control the lighting device to output target special effect lights in real time according to the user's selection;

[0053] The microcontroller is the processor of the lighting system. This embodiment does not require high performance of the processor, and only requires simple data transmission and processing.

[0054] The first interaction unit 203 includes at least one input and output module, configured to enable the user to select the target special effect light from at least two special effect lights;

[0055] The first interaction unit is connected to the microcontroller (ie, the processor) and can be: a touch screen, a wireless communication interface, a display and buttons, a dial, or a slider.

[0056] All elements that can realize input and output that can be thought of by those skilled in the art should be considered to be within the scope of protection of the present invention.

[0057] In this embodiment, preferably, the first interactive unit is a touch screen, on which icons and texts of various special effects can be displayed for the user to click; further optionally, when the user adjusts the adjustable parameters, the changes in the parameters are displayed in real time on the screen.

[0058] The first interaction unit can be provided in the same device as the microcontroller, lighting device, etc., and be directly electrically connected thereto; or it can be designed to be separate and communicate with the controller or lighting device via wireless communication; for convenience, the first interaction unit can also be designed as a detachable component;

[0059] Furthermore, when a separate design is performed, the first interaction unit can be directly set in the mobile device, or directly use the touch screen of the mobile device to communicate with the lighting system body through wireless communications such as Bluetooth and WiFi.

[0060] Furthermore, when the first interactive unit, the microcontroller and the lighting device are arranged in the same device, that is, the first interactive unit is arranged in the main body of the lighting system, a lighting control module can also be set in the mobile device at the same time to achieve the same function as the first interactive unit.

[0061] The special effect array storage unit 2021 is used to store multiple data packets; each of the data packets stores a special effect array, and the special effect array in each data packet corresponds to a unique special effect light;

[0062] This embodiment has two optional implementations, namely: the special effect storage unit 2021 can be a part of the microcontroller, or can be an independent storage unit. This embodiment describes it as a part of the microcontroller as a preferred implementation.

[0063] The microcontroller selects a corresponding target data packet based on the value of at least one preset adjustable parameter and the target special effect light selected by the user, and outputs the target special effect array in the target data packet in real time through the lighting device to generate the target special effect light; wherein the storage structure of the multiple data packets is a tree structure, and each node corresponds to a specific range of the adjustable parameter, a specific value of the adjustable parameter range, or the special effect light;

[0064] The value of the adjustable parameter can be adjusted by the user in real time by directly inputting the parameter value; or, it can be adjusted from large to small or from small to large; when the user makes the adjustment, the microcontroller switches the corresponding target special effect array in real time for output.

[0065] In an optional embodiment, there is only one adjustable parameter, which is the lumen value;

[0066] In this embodiment, an optional example uses the adjustable parameter as a first-level child node and the special effect light as a leaf node. Since there is only one adjustable parameter, there is no other node between the leaf node and the first-level child node.

[0067] Optionally, each first-level child node corresponds to a specific adjustable parameter value, or a range of adjustable parameter values. The following description will take the adjustable parameter value range as an example:

[0068] The lumen value (also called brightness value) is divided into 10 lumen value ranges according to the power, namely:

[0069] 1-10%;

[0070] 10-20%; ...

[0072] 90%-100%;

[0073] There are 10 first-level child nodes, which correspond one-to-one to the above lumen value ranges.

[0074] Each lumen value range corresponds to multiple special effect lights, such as:

[0075] There are 8 secondary child nodes (i.e. leaf nodes) in the 1-10% lumen value range. Each leaf node corresponds to a special effect light, such as: flash, flame, screen, lightning, pulse, fireworks, shutter, and explosion.

[0076] Furthermore, a lightning node within the 1-10% lumens range corresponds to a data packet containing an array of special effects that can be output as a lightning waveform curve. The lumens value of each value in this special effects array is also the lowest value (corresponding to 1-10%). For example, if the brightest and dimmest lightning values ​​have their own ranges, and each value is evenly spaced to 10 within their respective ranges, then each value in the current lightning special effects array is the lowest of the 10 values.

[0077] In this embodiment, the number of data packets (ie, the number of special effect arrays) is 10×8=80.

[0078] After the user turns on the lighting system, the first interactive unit will display 8 special effect lights in the form of pictures + text for the user to choose. At this time, the lighting device 201 will output the default normal light, or display the special effect light when it was turned off last time.

[0079] Optionally, in this embodiment, the lumen value may be a system preset value, such as 50-60%; it may be a value saved when the system was last shut down; a corresponding lumen value range may be pre-selected based on user usage habits (such as obtaining a user's fingerprint, facial contour, or iris, and determining the user's identity accordingly); or a corresponding lumen value range may be selected based on the surrounding environment (such as selecting 20-30% when the light is dim).

[0080] After the user selects the corresponding special effect lighting, the microcontroller will select the corresponding special effect array under the corresponding lumen value range node for output based on the user-selected special effect and lumen value range. The lumen value range is determined according to the method in the previous paragraph.

[0081] The user can adjust the lumen value before or after selecting a special lighting effect. For example, by directly entering a lumen value through the first interactive unit, the lighting system will then output the corresponding special effect array in real time based on the newly entered lumen value. Because the lighting system of the present invention changes the special lighting effect in real time based on the user's adjustments, the user can also continuously adjust the lumen value based on the displayed special lighting effect.

[0082] Another optional embodiment uses the special effect light as a first-level child node and the adjustable parameter as a leaf node. As in the previous embodiment, there is no other node between the leaf node and the first-level child node.

[0083] Optionally, each leaf node corresponds to a specific adjustable parameter value, or a range of adjustable parameter values. The following description will be given using specific adjustable parameter values ​​as an example:

[0084] Preferably, there are 8 special effect lights, such as flash, flame, screen, lightning, pulse, fireworks, shutter, and explosion; and the first-level child nodes correspond to each one, so there are 8 of them.

[0085] Assuming that the lumen value has 100 scales from low to high, that is, there are 100 values, then each first-level child node corresponds to 100 leaf nodes, corresponding to lumen values ​​1-100;

[0086] For example, there are 100 leaf nodes under the first-level node of the flame special effect.

[0087] Taking the array corresponding to the leaf node with a lumen value of 10 as an example, this array is a flame special effect array, but the value range of each number in the array is divided into 100 parts from small to large, and the value in the current array corresponds to the 10th part.

[0088] In this embodiment, the number of data packets, that is, the number of special effect arrays is: 100×10=1000.

[0089] In an alternative embodiment, the range of values ​​in the array cannot be divided into 100 equal parts, or dividing into 100 parts would require more storage space, or for other reasonable reasons, the range of values ​​in the array is divided into multiple groups, such as 20 groups, each with a single uniform value. The special effects arrays for the five leaf nodes with lumen values ​​of 1-5 are then identical. Alternatively, different special effects can be grouped differently. For example, the special effects array for the flame effect can be divided into 20 groups based on lumen value, while the special effects array for the shutter effect can be divided into only 5 groups.

[0090] There is no obvious difference when the user operates. The user just makes the selection based on the special effects first and then the lumen value.

[0091] The above implementation mode is only described for the case where there is one adjustable parameter, which should not be regarded as limiting the scope of protection of the present invention. Technical solutions for multiple adjustable parameters that can be reasonably implemented by those skilled in the art should also fall within the scope of protection of the present invention. For example, when two adjustable parameters are included, the tree structure should include three layers of child nodes, namely: first-level child nodes, second-level child nodes, and leaf nodes. If the degrees of the root node, first-level child node, and second-level child node are 10, 10, and 8 respectively, the number of leaf nodes is: 10×10×8=800, that is, 800 special effect arrays.

[0092] Optionally, the lighting system includes at least one independent parameter;

[0093] When there are multiple independent parameters, the storage structure of the multiple independent parameters is a tree structure.

[0094] Optionally, it further includes an independent parameter storage unit for storing independent parameters; the independent parameters are matched and outputted correspondingly with the special effect array.

[0095] Adjustable parameters include at least one or more of the following parameters:

[0096] Brightness (lumens), color temperature, frequency;

[0097] Independent parameters include at least one or more of the following parameters:

[0098] Brightness (lumens), color temperature, frequency;

[0099] Matching output refers to matching output through lighting equipment, specifically:

[0100] The lighting device includes light-emitting elements for generating light effects. These elements output different power levels in a timed sequence based on independent parameters and the special effects array. Optionally, when the adjustable or independent parameters include color temperature, the light-emitting elements include at least two, one producing cool light (preferably white) and the other producing warm light (preferably red). Adjusting the power of these two light-emitting elements adjusts the color temperature.

[0101] This embodiment has two optional implementations: the independent parameter storage unit is part of the microcontroller; or the independent parameter storage unit is an independent storage unit; further, the independent parameter storage unit and the special effects array storage unit are two storage spaces of the same memory. It should be noted that this is not a limitation of the present invention. If a person skilled in the art configures the independent storage unit and the special effects array storage unit as two completely independent memories in hardware, it should also fall within the scope of protection of the present invention.

[0102] In the above special effects arrays, each special effects array has been set according to the adjustable parameter values ​​or adjustable parameter ranges of its corresponding parent nodes. In other words, each special effects array has the corresponding adjustable parameters set, and the special effects arrays of the same special effect under different parent nodes are also different.

[0103] Correspondingly, the independent parameters are not preset into the special effects array, but are matched with the special effects array when output. It should be noted that when describing the aforementioned matching output, those skilled in the art often set up a "mixer" or "mixing unit" in the flow chart, such as mixing and modulating the special effects array and the corresponding independent parameters, but in this embodiment, when actually outputting, the independent parameters and the special effects array are directly notified to the matching output. Of course, the matching here refers to a strict matching in time. When matching the output, the two will naturally "mix" with each other, but there is no "calculation" here, and there is no calculation process.

[0104] In an optional embodiment, the independent parameter is not adjustable.

[0105] That is, the independent parameter is a constant value for all special effects; or, each special effect will have a specific independent parameter value, such as different independent parameter values ​​for lightning and fire; or, each special effect has a matching independent parameter array; but in short, the independent parameters here are not adjustable, but are matched with the special effect array during output.

[0106] In another optional embodiment, there is at least one specific special effect light, and the independent parameter corresponding to the specific special effect light is adjustable.

[0107] That is, corresponding to the previous embodiment, at least one independent parameter or independent parameter array matched by the special effect array can be adjusted in real time.

[0108] Optionally, the lighting system includes a second interaction unit 204;

[0109] The second interaction unit comprises at least one mechanical input element 2041;

[0110] The values ​​of the adjustable parameters can be adjusted by the user in real time, including:

[0111] The user adjusts the value of the adjustable parameter from large to small or from small to large through the mechanical input element; or

[0112] The user directly inputs the parameter value through the input / output module, or adjusts it from large to small or from small to large.

[0113] In a preferred embodiment, the mechanical input element is a circular knob, and the value of the adjustable parameter is adjusted by rotating the knob.

[0114] Optionally, the mechanical input unit includes a plurality of mechanical input elements; the number of the mechanical input elements is greater than or equal to the number of the adjustable parameters;

[0115] When the value of the adjustable parameter is adjusted in real time by the user through the mechanical input unit, each adjustable parameter has a one-to-one corresponding mechanical input element.

[0116] In a preferred embodiment of the present invention, the adjustable parameters are parameters related to the special effect array. A specific example is described as follows:

[0117] The lightning special effects array includes a set of lumen values ​​arranged in chronological order, and the adjustable parameter is the lumen value. Therefore, this embodiment adjusts and groups each special effects array according to the lumen value range; correspondingly, the independent parameter is not a related parameter, such as color temperature, which is an independently output value.

[0118] Optionally, the number of the mechanical input elements is at least one more than the number of the adjustable parameters; at least one of the mechanical input elements is used to input the value of at least one independent parameter;

[0119] The value of the independent parameter is not adjustable when controlling the lighting device to output the target special effect light in real time according to the user's selection; it can be adjusted in real time when the user selects ordinary light.

[0120] Optionally, the independent parameter includes color temperature.

[0121] Optionally, the special effect lighting includes at least the following special effects suitable for photography:

[0122] Flash, flame, screen, lightning, pulse, fireworks, shutter, explosion.

[0123] On the other hand, an embodiment of the present invention provides a lighting control module 001 provided in a mobile device, which can communicate wirelessly with the above-mentioned lighting system to achieve the same function as the first interaction unit.

[0124] Figure 3 This is a structural block diagram of the wireless connection between the lighting control module 001 and the lighting system.

[0125] On the other hand, an embodiment of the present invention provides a lighting device, in which the above-mentioned lighting system is used.

[0126] The beneficial effects of the present invention are as follows: the present invention stores the special effect arrays of special effect lights in a tree structure according to the special effect categories and various lighting parameters, and selects the special effect arrays on the corresponding leaf nodes of the tree structure for output in real time according to the user's input, adjustment or selection. Since each special effect array is pre-existing in the lighting system, there is no need for temporary complex modulation, which greatly reduces the user operation complexity of "special effect modulation"; because the system only needs to "select" and does not need to perform any "calculation", the stability and efficiency of the system processing are improved.

[0127] The present invention will be further described below with reference to specific examples with reference to the accompanying drawings.

[0128] Figure 4 A flowchart for special effect lighting adjustment in the prior art;

[0129] As shown in the figure, in existing technology, after the input unit inputs various parameters, the processor generates the required output array based on the user's input parameters. If there are different types of parameters, they need to be mixed before output. In practice, "mixing" is not a calculation process, but simply aligning the timestamps of the different types of parameters (also known as matching) and outputting them after alignment.

[0130] The input unit here is generally a mechanical unit. To enhance the user experience, a display unit is generally provided to display the parameters input by the user in real time.

[0131] This solution can be achieved through products similar to flash boxes in the field of stage and movie shooting. However, it should be noted that due to the difference in fields, the special effects required in the field of photography are relatively simpler than those in stage and movie shooting. They do not use very complex lighting systems and generally only require a photography light. Therefore, the "photography flash box" in the existing technology is different from the attached Figure 1 The flash box in the example is much simpler than the one in the example, so I will not explain it in detail.

[0132] Figure 5 This is a flowchart of special effect lighting adjustment in this embodiment;

[0133] As shown in the figure, this embodiment is described by taking a photography scene as an example, wherein the lighting is preferably a photography light.

[0134] A microcontroller is used to control the lighting device to output target special effect lights in real time according to the user's selection;

[0135] The microcontroller is the processor of the lighting system. This embodiment does not require high performance of the processor, and only requires simple data transmission and processing.

[0136] A first interaction unit includes at least one input and output module, configured to enable a user to select the target special effect light from at least two special effect lights;

[0137] This embodiment is described using a touch screen as an example, where icons and text of various special effects can be displayed on the screen for the user to select. Optionally, when the user adjusts the adjustable parameters, the changes in the parameters can be displayed on the screen in real time.

[0138] The first interaction unit, the microcontroller, the lighting device, etc. are arranged in the same device.

[0139] It also includes a special effect array storage unit for storing a plurality of data packets; each of the data packets stores a special effect array, and the special effect array in each data packet corresponds to a unique special effect light;

[0140] It should be noted that the special effect array storage unit can be a part of the microcontroller, or a storage unit independent of the microcontroller. This embodiment is described using it as an independent storage unit as an example.

[0141] In this embodiment, a mechanical input element is selected as a preferred implementation of the second interaction unit for further explanation.

[0142] The microcontroller selects a corresponding target data packet based on the value of at least one adjustable parameter input by the user through the mechanical input element and the target special effect light selected by the user through the first interactive unit, and outputs the target special effect array in the target data packet in real time through the lighting device to generate the target special effect light; wherein the storage structure of the multiple data packets is a tree structure, and each node corresponds to a specific range of the adjustable parameter, a specific value of the adjustable parameter range, or the special effect light;

[0143] The value of the adjustable parameter can be adjusted by the user in real time by directly inputting the parameter value; or, it can be adjusted from large to small or from small to large; when the user makes the adjustment, the microcontroller switches the corresponding target special effect array in real time for output.

[0144] As shown in Figure 4, there is only one adjustable parameter, which is the lumen value. In this implementation, the adjustable parameter is used as a first-level child node, and the special effect light is a leaf node. Since there is only one adjustable parameter, there are no other nodes between the leaf node and the first-level child node. Each first-level child node corresponds to a range of adjustable parameter values:

[0145] The lumen value (also called brightness value) is divided into 10 lumen value ranges according to the power, namely:

[0146] 1-10%;

[0147] 10-20%; ...

[0149] 90%-100%;

[0150] There are 10 first-level child nodes, which correspond one-to-one to the above lumen value ranges.

[0151] Each lumen value range corresponds to 8 special effect lights:

[0152] There are 8 secondary child nodes (i.e. leaf nodes) in the 1-10% lumen value range. Each leaf node corresponds to a special effect light, such as: flash, flame, screen, lightning, pulse, fireworks, shutter, and explosion.

[0153] Optionally, it further includes an independent parameter storage unit for storing independent parameters; the independent parameters are matched and outputted correspondingly with the special effect array.

[0154] In this embodiment, the independent parameter storage unit is provided in the microcontroller. In another optional embodiment, there is no specific independent parameter storage unit, and the independent parameter is input by the user and directly output by the lighting device after passing through the processor.

[0155] In the above special effects arrays, each special effects array has been set according to the adjustable parameter values ​​or adjustable parameter ranges of its corresponding parent nodes. In other words, each special effects array has the corresponding adjustable parameters set, and the special effects arrays of the same special effect under different parent nodes are also different.

[0156] Correspondingly, the independent parameters are not preset into the special effects array, but are matched with the special effects array when output. It should be noted that when describing the aforementioned matching output, those skilled in the art often set up a "mixer" or "mixing unit" in the flow chart, such as mixing and modulating the special effects array and the corresponding independent parameters, but in this embodiment, when actually outputting, the independent parameters and the special effects array are directly notified to the matching output. Of course, the matching here refers to a strict matching in time. When matching the output, the two will naturally "mix" with each other, but there is no "calculation" here, and there is no calculation process.

[0157] In an optional embodiment, the independent parameter is not adjustable.

[0158] That is, the independent parameter is a constant value for all special effects; or, each special effect will have a specific independent parameter value, such as different independent parameter values ​​for lightning and fire; or, each special effect has a matching independent parameter array; but in short, the independent parameters here are not adjustable, but are matched with the special effect array during output.

[0159] In another optional embodiment, there is at least one specific special effect light, and the independent parameter corresponding to the specific special effect light is adjustable.

[0160] That is, corresponding to the previous embodiment, at least one independent parameter or independent parameter array matched by the special effect array can be adjusted in real time.

[0161] Since whether independent parameters and adjustable parameters are adjustable and how to adjust them are related to the requirements of various special effects, the following will use the three special effect lights preferred in this embodiment as an example to illustrate whether the parameters are adjustable in conjunction with the accompanying drawings.

[0162] As shown in the figure, Figure 6 This is a graph showing the change over time of the Flash effect array output. The horizontal axis is time and the vertical axis is lumen value.

[0163] The adjustable parameter is the lumen value, and the independent parameter is the color temperature value, both of which are adjustable. Preferably, both are adjustable in real time. Preferably, the maximum value in the special effect array curve is the user-preset adjustable parameter value (lumen value); in another optional embodiment, the mean value can also be used as the user-preset adjustable parameter value.

[0164] Preferably, the independent parameter color temperature value is adjustable. To ensure the flash effect, the preferred adjustment range is 2700K~6500K.

[0165] like Figure 6 As shown in the figure, assuming that the user presets a lumen value of 100lm and a color temperature of 3000K, the flash effect array will output lumen values ​​according to the curve shown in the figure (0-100-0-100...0-100-0) and maintain a constant color temperature of 3000K.

[0166] Optionally, during the special effect output process, the user can also adjust the lumen value or color temperature value. For example, if the user adjusts the color temperature value to 3600K, the special effect output will be adjusted to a constant color temperature of 3600K in real time, but the lumen output will not be affected.

[0167] In another optional embodiment, a frequency parameter is further included. The frequency parameter can be used as an adjustable parameter or as an independent parameter. It should be further explained that, in an optional embodiment:

[0168] If there is more than one independent parameter, the multiple independent parameters are stored in a tree structure, and are selected according to user input like adjustable parameters, and are matched with the special effect array for output.

[0169] Figure 7 A graph showing the brightness (lumens) and color temperature changing over time when the Flame effect array is output;

[0170] The horizontal axis is time, and the vertical axis is lumen value; the curved line is lumen value, and the straight line is color temperature. The color temperature is only for reference and the corresponding value is not marked on the vertical axis.

[0171] As shown in the figure, the adjustable parameter is the lumen value, and the independent parameter is the color temperature value. The lumen value is adjustable, while the independent parameter color temperature is not adjustable and is always set to a warm color temperature. In this embodiment, the color temperature is preferably set to 2700K. Those skilled in the art may of course set the color temperature to other values, but this should not be construed as a limitation of the present invention.

[0172] As with the flash effect, the color temperature is constant when the special effect array is output. Optionally, the adjustable parameter value (lumen value) input by the user is used as the mean value of the special effect array; or as the peak value of the special effect array.

[0173] Figure 8 A graph showing how color temperature and brightness change over time when outputting a screen effects array.

[0174] As shown in the figure, the horizontal axis is time and the vertical axis is lumen value; the maximum brightness of the Screen effect is the lumen value set by the user; the color temperature is only for reference and the corresponding value is not marked on the vertical axis.

[0175] The difference between screen effects and flash effects is that when the independent parameter color temperature is output in the special effects array, the matching color temperature value is a curve that changes over time, not a single constant value.

[0176] Furthermore, the color temperature is adjustable:

[0177] In an optional embodiment, the color temperature is adjusted only to the peak value. After the peak value is adjusted, the valley value remains unchanged, and the amplitude of the entire color temperature value curve changes accordingly. In this embodiment, the valley value of the color temperature value curve is constant, the minimum value of the peak value adjustment is the valley value, and the maximum value is 6500k.

[0178] In another optional embodiment, the color temperature is adjusted by adjusting all values ​​on the entire color temperature value curve simultaneously. In this case, the adjustable color temperature value is the average value of the entire color temperature value curve, and its adjustable range is 2700K-6500K.

[0179] Optionally, the color temperature can be adjusted continuously or in steps. When adjusted in steps, in this embodiment, each 100K is preferably regarded as a step.

[0180] Figure 8 This is only one implementation of screen special effect lighting and is not intended to limit the present invention. Optionally, in screen special effect lighting, the color temperature output can also be a straight line that matches one cycle of the lumen value curve, just like the flash effect, that is, the color temperature is a constant value.

[0181] To ensure the output effect, the color temperature adjusted by the user can be optionally maintained during the special effect display process. Specifically, the output of the user adjustment can be delayed, or the adjustment can be performed when the special effect is exited.

[0182] "Tree storage" itself is not a new technology, but in stage scenes or movie shooting scenes, there are many lighting devices and the requirements for lighting effects are much higher, which requires coordination of multiple devices. If the solution of the present invention is adopted, a huge storage space and a very complex storage structure will be required. At the same time, the equipment corresponding to the lighting effect solution in this scene does not require "portability". The equipment can be very large, and the processor can also use a more expensive and efficient processor. Under this premise, directly generating "fully customized" lighting effects that better meet the requirements of lighting technicians through "calculation" is a better solution with better robustness. Therefore, those skilled in the art have no reason and no motivation to develop a technical solution such as the present invention.

[0183] In summary, the present invention applies "tree storage" to the field of photography that requires "portability", utilizes the existing "microprocessor" and a smaller memory to store the special effects array according to adjustable parameters, and further adds independent parameters, creatively realizing a "lightweight and customizable" lighting effect implementation solution compared to stage scenes.

[0184] The beneficial effects of the present invention are as follows: the present invention stores the special effect arrays of special effect lights in a tree structure according to the special effect categories and various lighting parameters, and selects the special effect arrays on the corresponding leaf nodes of the tree structure for output in real time according to the user's input, adjustment or selection. Since each special effect array is pre-existing in the lighting system, there is no need for temporary complex modulation, which greatly reduces the user operation complexity of "special effect modulation"; because the system only needs to "select" and does not need to perform any "calculation", the stability and efficiency of the system processing are improved.

[0185] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
