[0033] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way are interchangeable where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover other inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0034] The method embodiments provided in the embodiments of the present application can be executed in a light-emitting device. Taking the operation on a light-emitting device as an example, FIG1 is a hardware structure block diagram of a light-emitting device of a brightness adjustment method of an embodiment of the present application. As shown in FIG1 , the light-emitting device may include one or more (only one is shown in FIG1 ) processors 102 (the processor 102 may include but is not limited to a microprocessor (Microprocessor Unit, abbreviated as MPU) or a programmable logic device (Programmable logic device, abbreviated as PLD)) and a memory 104 for storing data. In an exemplary embodiment, the above-mentioned light-emitting device may also include a transmission device 106 and an input and output device 108 for communication functions. It can be understood by those skilled in the art that the structure shown in FIG1 is only for illustration, and it does not limit the structure of the above-mentioned switching device. For example, the light-emitting device may also include more or fewer components than those shown in FIG1 , or a different configuration having the same function as that shown in FIG1 or more functions than those shown in FIG1 .

[0035] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the brightness adjustment method in the embodiment of the present application. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, implementing the above-mentioned method. The memory 104 may include a high-speed random access memory and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include a memory remotely located relative to the processor 102, and these remote memories may be connected to the light-emitting device via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0036] The transmission device 106 is used to receive or transmit data via a network.

[0037] In this embodiment, a brightness adjustment method is provided, which is applied to the above-mentioned light-emitting device. FIG2 is a flow chart of the brightness adjustment method according to the embodiment of the present application, and the flow chart includes the following steps:

[0039] It should be noted that since the color of the white cloud area in the picture layer is white when the light-emitting device is in the off state, when the brightness of the lamp beads with different color temperatures is adjusted, the color of the white cloud area (which can be understood as the above-mentioned display parameters) changes accordingly. For example, when the brightness of the warm white lamp beads is higher, the white cloud area displays yellow; when the brightness of the cold white lamp beads is higher, the white cloud area displays white; or, the color or color temperature displayed in the white cloud area is formed by the mixed light of lamp beads with multiple color temperatures.

[0042] Through the above steps, a first set of lamp beads for adjusting the display parameters of the white cloud area of ​​the light output cover of the light-emitting device is determined, and a first dynamic control strategy for the first set of lamp beads is determined; then, the brightness of each lamp bead in the first set of lamp beads is adjusted according to the first dynamic control strategy. Since there is a white cloud area on the light output cover of the light-emitting device, and the display parameters of the white cloud area can be controlled by the dynamic control strategy to make the white cloud area present a dynamic effect, the above technical solution solves the problem of high cost and complex structure of the light-emitting device presenting a virtual dynamic white cloud visual effect in the prior art.

Y / Q, m is a positive integer, and m is less than Q.

[0207] Through the above embodiments, the final effect presented by the light-emitting device is: controlling the first color temperature lamp beads of column Q in the second lamp bead set to adjust from the first brightness to the second brightness; when the color temperature of the first color temperature lamp beads of column Q in the second lamp bead set is adjusted to the second brightness, again controlling the brightness of the first color temperature lamp beads of column m in column Q in the second lamp bead set to adjust from the second brightness to the first brightness, and controlling the brightness of the first color temperature lamp beads of column m adjacent to column Q in the second lamp bead set to adjust from the first brightness to the second brightness; and / or sequentially controlling the first color temperature lamp beads of column Q in the second lamp bead set to adjust from the first brightness to the second brightness. The second color temperature lamp beads in the first column are adjusted from the third brightness to the fourth brightness; when the color temperature of the second color temperature lamp beads in the Q column in the second lamp bead set is adjusted to the fourth brightness, the brightness of the second color temperature lamp beads in the m column in the Q column in the second lamp bead set is again controlled to be adjusted from the fourth brightness to the third brightness, and the brightness of the second color temperature lamp beads in the m column adjacent to the Q column in the second lamp bead set is controlled to be adjusted from the third brightness to the fourth brightness; that is, finally in the second lamp bead set, only the brightness of the first color temperature lamp beads in the Q column is the second brightness, and the brightness of the second color temperature lamp beads in the Q column is the fourth brightness.

[0208] Optionally, the above embodiment is described by taking B=1, Q=4, n=0, m=1, the first color temperature lamp bead is a warm white lamp bead, and the second color temperature lamp bead is a cool white lamp bead as an example:

[0209] In the case of Q=4, first, the warm white lamp beads in the 1st to 4th columns of the second lamp bead set are controlled to change, and when the brightness of the warm white lamp beads in the 1st to 4th columns of the second lamp bead set is adjusted to the second brightness, the brightness of the warm white lamp beads in the 1st column of the second lamp bead set is controlled to be adjusted from the second brightness to the first brightness, and the brightness of the warm white lamp beads in the 5th column of the second lamp bead set is controlled to be adjusted from the first brightness to the second brightness; then, when the brightness of the warm white lamp beads in the 5th column of the second lamp bead set is adjusted to the second brightness, the brightness of the warm white lamp beads in the 2nd column of the second lamp bead set is controlled to be adjusted from the second brightness to the first brightness, and the brightness of the warm white lamp beads in the 6th column of the second lamp bead set is controlled to be adjusted from the first brightness to the second brightness... and so on, until the brightness of the warm white lamp beads in the Yth column of the second lamp bead set is adjusted to the second brightness; and / or,

[0210] Control the changes of the cool white lamp beads in the 1st to 4th columns in the second lamp bead set. When the brightness of the cool white lamp beads in the 1st to 4th columns in the second lamp bead set is adjusted to the fourth brightness, control the brightness of the cool white lamp beads in the 1st column of the second lamp bead set to be adjusted from the fourth brightness to the third brightness, and control the brightness of the cool white lamp beads in the 5th column of the second lamp bead set to be adjusted from the third brightness to the fourth brightness; thereafter, when the brightness of the cool white lamp beads in the 5th column of the second lamp bead set is adjusted to the fourth brightness, control the brightness of the cool white lamp beads in the 2nd column of the second lamp bead set to be adjusted from the fourth brightness to the third brightness, and control the brightness of the cool white lamp beads in the 6th column of the second lamp bead set to be adjusted from the third brightness to the fourth brightness... and so on, until the brightness of the cool white lamp beads in the Yth column of the second lamp bead set is adjusted to the fourth brightness.

[0211] The final rendering effect is shown in Figure 18.

[0212] Method 2: Determine at least one fourth lamp bead set in the first lamp bead set; control the brightness of at least one first color temperature lamp bead in the at least one fourth lamp bead set to adjust from the first brightness to the second brightness; and / or control the brightness of at least one second color temperature lamp bead in the at least one fourth lamp bead set to adjust from the third brightness to the fourth brightness.

[0213] Through the above-mentioned second method, non-directional lamp bead display of the light-emitting device can be achieved.

[0214] Optionally, in the case where the light-emitting device is a direct-light type, determining a first lamp bead set for adjusting the display parameters of at least all or part of the white cloud area corresponding to the light-emitting device includes: determining a first lamp bead area in the light source assembly, wherein the similarity between the pattern composed of the lamp beads in the first lamp bead area and the pattern of the white cloud area is greater than a first preset threshold, and the first lamp bead area includes all or part of the lamp beads of the light-emitting device; determining the lamp beads in the first lamp bead area as the first lamp bead set.

[0215] It is understandable that the first lamp bead area is determined in the light source assembly, wherein the first lamp bead area of ​​the light source assembly should have a high similarity with the white cloud area of ​​the light output cover.

[0216] For example, the first preset threshold may be set to 80%. When the similarity between the first lamp bead area of ​​the light source assembly and the white cloud area of ​​the light output cover is greater than or equal to 80%, the lamp beads in the first lamp bead area are determined to be the first lamp bead set.

[0217] For example, when the above-mentioned first preset threshold is 10% or lower, the first lamp bead area includes all the lamp beads of the light-emitting device; when the first preset threshold is a value greater than 10%, the first lamp bead area includes: part of the lamp beads of the light-emitting device.

[0218] Optionally, in the case where the light-emitting device emits light from the side, determining a first lamp bead set for at least adjusting the display parameters of all or part of the white cloud area corresponding to the light-emitting device includes: determining a second lamp bead area in the light source assembly, wherein the light-emitting coverage area of ​​the lamp beads in the second lamp bead area includes: all or part of the white cloud area, and the second lamp bead area includes all or part of the lamp beads of the light-emitting device; determining the lamp beads in the second lamp bead area as the first lamp bead set.

[0219] It is understandable that, when the light emitting device emits light from the side, it is also necessary to determine the second lamp bead area corresponding to the white cloud area, wherein the light emitted by the second lamp bead area should cover the white cloud area.

[0220] Optionally, determining the first dynamic control strategy of the first lamp bead set includes: determining the scene information to be executed, and determining the color temperature and brightness of the white cloud area based on the scene information; determining the first dynamic control strategy of the first lamp bead set based on the color temperature and brightness of the white cloud area.

[0221] It is understood that the color temperature and brightness of the white cloud area can be determined by determining scene information. For example, the scene area can be a sunset scene, a dark cloud scene, or a clear sky scene. Each scene information corresponds to a brightness and speed selection scheme for a lamp bead. When the corresponding scene information is selected, the brightness and speed scheme of the corresponding lamp bead is turned on, and the first dynamic control strategy of the first lamp bead set is determined based on the color temperature and brightness of the white cloud area.

[0222] Optionally, a fifth lamp bead set is determined for adjusting display parameters of other areas of the picture layer of the light output cover, wherein the light source assembly includes at least: the fifth lamp bead set, and the first dynamic control strategy simultaneously adjusts the brightness of each lamp bead in the fifth lamp bead set and the first lamp bead set; or, a second dynamic control strategy is determined for the fifth lamp bead set; and the brightness of each lamp bead in the fifth lamp bead set is adjusted according to the second dynamic control strategy.

[0223] It is understandable that the light-emitting device has other areas besides the white cloud area, such as the blue sky area, the grass area, etc. When determining the dynamic control strategy of the white cloud area, the lamp bead collection of other areas can be determined, and the same or different dynamic control strategy as the white cloud area can be selected.

[0224] Optionally, after determining the first dynamic control strategy of the first lamp bead set, the method also includes: receiving an adjustment instruction sent by an external control device; adjusting the first dynamic control strategy according to the adjustment instruction, and adjusting the brightness of each lamp bead in the first lamp bead set according to the adjusted first dynamic control strategy.

[0225] It is understood that the lighting device can also receive adjustment instructions sent by an external control device according to the determined first dynamic control strategy, so as to control the speed and pattern of row-by-row lighting of the lamp beads through external control. For example, external control can be performed through a remote control, wall switch, wall control panel, etc.

[0226] Optionally, adjusting the brightness of each lamp bead in the first lamp bead set according to the first dynamic control strategy includes: determining the current input to each lamp bead in the first lamp bead set according to the first dynamic control strategy; and adjusting the brightness of each lamp bead in the first lamp bead set by the current.

[0227] It is understandable that the brightness of each lamp bead can be adjusted by adjusting the current in each lamp bead. The larger the current, the brighter the lamp bead, and the smaller the current, the lower the brightness of the lamp bead.

[0228] Furthermore, each lamp bead can be connected in parallel, so that when one of the lamp beads is adjusted, the brightness of other lamp beads will not be affected.

[0229] In order to better understand the process of the above-mentioned brightness adjustment method, the implementation method flow of the above-mentioned brightness adjustment is described below in combination with an optional embodiment, but it is not used to limit the technical solution of the embodiment of the present application.

[0230] This embodiment provides a simple dynamic lighting fixture with a virtual sky scene. It not only provides a clear blue sky and white cloud pattern, but also offers a dynamic visual experience of a virtual celestial scene, creating a sense of undercurrents flowing within the clouds and allowing for imagination. This creates a sense of being immersed in a comfortable, healthy, and natural lighting environment, achieving a positive effect of euphoria. Figure 4 illustrates the appearance of a simple dynamic lighting fixture with a virtual sky scene according to an embodiment of the present application. As shown in Figure 4, the dynamic lighting fixture includes a light source assembly, a chassis, a light output cover with a blue sky and white cloud image layer, and a control module. FIG5 is a schematic diagram (1) of the structure of a direct-down type dynamic lighting fixture with a virtual sky scene according to an embodiment of the present application, and FIG6 is a schematic diagram (2) of the structure of a direct-down type dynamic lighting fixture with a virtual sky scene according to an embodiment of the present application. As shown in FIG5 and FIG6, the light source assembly is located on the chassis, the light output cover is connected to the chassis and arranged directly opposite the light source assembly, and the lamp beads of different light colors that constitute the light source assembly are lit or dimmed (with a variable range of 0-100%) under the control of the control module. The light color of the LED lamp beads of the same color temperature is arranged adjacent to each other along the directional change direction, and the LED lamp beads of different color temperatures are arranged at intervals so that the areas where the lamp beads of the same color temperature are lit or extinguished row by row have the same color output on the light output cover, or the color or color temperature output on the light output cover is formed by mixing the light of lamp beads of multiple color temperatures. Based on cost factors and the fact that the entire row is changed during directional change, the light source assembly is preferably composed of multiple light strips arranged in parallel.

[0231] Among them, the light hood can be fixed on the chassis through an outer frame, or it can be directly connected to the chassis. In order to make the multiple lamps after splicing have a stronger virtual sense of blue sky, and to facilitate the lamps to be embedded or ceiling-mounted and suspended, the light hood preferably adopts a three-dimensional polygonal structure design. When splicing, the lampshades can be in direct contact with each other without being affected by the frame, which is conducive to forming a seamless light-emitting surface.

[0232] The light emitting cover of this embodiment is also provided with a magnet, and the above-mentioned chassis contains an iron metal frame, so that the light emitting cover can be connected to the chassis in a separate manner; the blue sky and white cloud image layer is attached to the light emitting cover by printing, spray painting or silk screen printing. In order to facilitate the processing of the image layer, the light emitting cover is preferably blow-molded or multi-faceted. Among them, the image layer contains at least part of the white cloud pattern, so that the area where the white clouds of the light emitting cover are located can more clearly feel the light color change. Figure 7 is a schematic diagram of the arrangement of the light source components and the control module arrangement of a direct-down dynamic lamp with a virtual sky scene according to an embodiment of the present application. As shown in Figure 7, the light source component composed of at least two LED lamp beads with different color temperatures dynamically changes alternately under the control of the control module, and its transformation schemes are:

[0233] Solution 1: The lamp beads change dynamically row by row according to the direction (from left to right, from top to bottom, diagonally from corner to corner, a single row changes row by row, or multiple rows can change row by row). The light mask will have a local area or the entire area of ​​the light color dynamically changing according to the direction, and output a dynamically changing light distribution (to simulate the movement of clouds in a certain direction);

[0234] Option 2: The lamp beads change in a non-directional dynamic manner (adjacent lamp beads with different light colors in a local area or adjacent lamp beads with different light colors in the entire area change alternately). The light output cover will show that the light color of the local area or the entire area changes dynamically in a non-directional manner and outputs a dynamically changing light distribution (to simulate the unbridled rolling of clouds).

[0235] Due to the different shades of color in the image layer, in order to clearly display the transformed light and color areas, at least one of the brightness and color temperature of the corresponding parts of the white cloud area and the blue sky area of ​​the image layer changes accordingly (for example, the brightness of part of the white cloud area changes from bright to dark, and the color dynamically changes to white, orange, gold, etc.; the brightness of part of the blue sky area changes from bright to dark, and the color can also dynamically change to dark blue, light blue, sunset sky, etc.) so that the interior of the light output cover with the blue sky and white cloud image layer presents a dynamic virtual visual effect, giving people a sense of picture and imagination space as if there is an undercurrent surging inside the clouds.

[0236] Figure 8 is a schematic diagram of the light color after transformation according to the embodiment of the present application in a complete row and full area transformation mode, and Figure 9 is a schematic diagram of the light color after transformation according to the embodiment of the present application in a complete row and local area transformation mode. As shown in Figures 8, 9 and 3, LED lamp beads of different color temperatures can be replaced by the light color after the complete row change during the dynamic row-by-row change process, or by the light color before and after the incomplete row transformation. The corresponding display on the light output mask is to realize the complete dynamic replacement of one light color with the previous light color along the corresponding boundary line of the light output mask, or at least two different row-by-row transformation modes in which only part of the opposite edges along the transformation direction on the light output mask are dynamically replaced. The shaded part represents the light color area after the change displayed on the light output mask.

[0237] Among them, b1, b2, and b3 are the instantaneous states of a1, a2, and a3 after the alternating changes from left to right in a directional and row-by-row manner. Among them, a1 to b1 indicates that the transformation mode is carried out in the entire area in a multi-row sequential manner, and the light color is transformed according to the entire row; and b1 also indicates that the entire area is undergoing light color transformation during non-directional alternating transformation; a2 to b2 indicates that the transformation mode is carried out in a local area of ​​a single row or multiple rows in a sequential manner, and the light color is transformed according to the entire row; and b2 also indicates that the local area is undergoing light color transformation during non-directional alternating transformation; a3 to b3 indicates that the transformation mode is carried out in a local area of ​​a single row or multiple rows in a sequential manner, and the light color is transformed according to an incomplete row; and b3 also indicates that the local area is undergoing light color transformation during non-directional alternating transformation.

[0238] Among them, the straight lines in Figures 8, 9, and 3 are mainly used to illustrate that the lamp beads perform row-by-row light color changes along the straight lines, which are actually reflected on the light output cover. Due to the influence of the uniformity and diffusion of the diffusion cover and the brightness differences of the lamp beads, the outer contour of the changed light color area is not a straight line visible to the naked eye. The figure is only expressed by straight lines to illustrate the position of the LED during the row-by-row change.

[0239] In addition, the LED lamp beads in the embodiments of the present application have different color temperatures. Warm white and cool white lamp beads with large color temperature differences are preferably used. RGB lamp beads with large color differences can also be used to emit light, so that after different color temperatures change in brightness and darkness, the changes in light color areas can be observed after passing through the blue sky and white cloud film.

[0240] The control module in the embodiment of the present application may also include a control receiving module to facilitate the control of the line-by-line conversion speed and the line-by-line conversion mode described above through an external controller; the external controller can be a remote control or a wall control panel or other wireless low-voltage control solution.

[0241] FIG10 is a schematic diagram of a straight-line splicing arrangement of dynamic lamps with virtual sky scenes according to an embodiment of the present application, and FIG11 is a schematic diagram of a field-shaped splicing arrangement of dynamic lamps with virtual sky scenes according to an embodiment of the present application. As shown in FIG10 and FIG11, signal input and output ports are also provided on the chassis of the lamps, which facilitate signal connection when different lamps are arranged in a straight line or a field shape as shown in the figure and spliced ​​into a whole. According to different splicing methods, in order to achieve the overall row-by-row conversion effect, the positions of the signal input / output ports are different. When the straight-line connection is used, the signal input / output port is located at the end face of the row-by-row conversion direction. To achieve the effect of line-by-line conversion signal series connection, when connected in a field shape, the signal input / output ends are respectively located at the end face of the line-by-line conversion direction and the end face of the extension direction of the row, so as to simultaneously play the role of converting the line length signal series connection; the receiving module is located on the main lamp, so that after splicing, the main and auxiliary lamps can be turned on or off line by line as a whole under the control of the controller in the same mode, and at the same time, the light output cover after splicing can form a larger area of ​​virtual blue sky dynamic scene; in order to make the virtual sense of the blue sky of multiple lamps after splicing stronger, the image layer usually adopts a complete pattern composed of various splicing bodies to facilitate seamless splicing and the integrity of the image layer after splicing.

[0242] FIG12 is an external view of a side-emitting structure with a dynamic lighting fixture having a virtual sky scene according to an embodiment of the present application; FIG13 is a cross-sectional schematic view of a side-emitting structure with a dynamic lighting fixture having a virtual sky scene according to an embodiment of the present application;

[0243] As shown in Figures 12 and 13, the lamp can also include a lighting module for providing daily lighting and a virtual scene light module, so that it can also provide lighting during the dynamic scene mode. The scene light module can adopt a side-emitting light structure, with an outer frame provided on the outside of its chassis, and the light source assembly is located on the outer frame. The light output cover with a blue sky and white cloud pattern outputs the light generated by the light source assembly outward through the transmission of the light guide plate and reflective paper.

[0244] FIG14 is a schematic diagram of the arrangement and position of a side-emitting structure light source component according to an embodiment of the present application. As shown in FIG14 , the LED lamp beads of different color temperatures on the light source components on both sides of the light guide plate are arranged at intervals along the length direction of the light board, and the direction of the dynamic row-by-row transformation will be carried out along the length direction of the light board. The dynamic row-by-row light color transformation can be that the light source components on both sides participate in the row-by-row transformation at the same time, or only the light source component on one side performs the row-by-row transformation. When the light source components on both sides transform row by row, whether the lamp beads of the same color temperature facing each other are transformed at the same time or the lamp beads of the same color temperature corresponding to each other in the oblique direction are transformed at the same time, the same light output cover is displayed as above. The complete whole-row conversion mode of the direct-down structure is the same. Figure 15 is a schematic diagram of the light color after the side-light emitting structure according to the embodiment of the present application is transformed by the complete whole-row and whole-area row-by-row conversion mode, and Figure 16 is a schematic diagram of the light color after the side-light emitting structure according to the embodiment of the present application is transformed by the complete whole-row and local area row-by-row conversion mode. As shown in Figures 15 and 16, the shaded part represents the light color area after the transformation after the light source components on both sides participate at the same time, where d1 is the dynamic transformation mode of c1 from multiple rows to the full area row by row, and d2 is the dynamic transformation mode of c2 from a single row or multiple rows to the local area row by row.

[0245] When only a single-sided light source assembly participates in the row-by-row conversion, due to differences in photoelectric properties such as color temperature and output brightness between the lamp beads on both sides, a light color dividing line is formed in the middle of the light guide plate. This dividing line, which is ultimately reflected back on the light output shield, often becomes a curve with unclear boundaries due to the influence of the light output shield's diffusion rate and the inconsistency of the lamp bead brightness before and after the conversion. Its visual presentation is similar to the aforementioned direct-down incomplete full-row conversion mode, except that one end of the conversion area is always located at the edge of the light output shield. FIG17 is a schematic diagram of the light color of a side-emitting structure after conversion according to an embodiment of the present application, which is converted in a half-area conversion mode and a partial-area conversion mode. FIG18 is a schematic diagram of the light color of a side-emitting structure after conversion according to an embodiment of the present application, which is converted in a half-area conversion mode and a partial-area conversion mode. As shown in FIG17 and FIG18, the shaded areas represent the converted light color areas. D3 is derived from C3 by the dynamic conversion mode of multiple rows in which the single-sided light source assembly participates, and D4 is derived from C4 by the dynamic conversion mode of a single row or multiple rows in which the single-sided light source assembly participates, which is a partial-area conversion mode. The most obvious feature of this mode is that the front and back light colors are always maintained on the light output mask during line-by-line conversion.
