[0032] The present disclosure will be further described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0033] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present disclosure.

[0034] Figure 1 FIG. 1 is a flow chart of an automatic lighting arrangement method according to an embodiment of the present disclosure. In one embodiment, the method includes:

[0035] S101, determining the initial position of one or more light sources to be arranged in the area to be lit according to area parameters, illumination requirements and types of light sources to be arranged in the area to be lit;

[0036] S102, determining predicted illumination parameters in the area to be lit according to the initial positions of the one or more light sources in the area to be lit;

[0037] S103: Determine the target positions of the one or more light sources to be arranged according to the comparison between the predicted lighting parameters and the standard values ​​of the lighting parameters in the area to be arranged.

[0038] In the embodiment of the present disclosure, the area parameters of the area to be lighted may include area type, area size, area shape, etc. The illumination requirement may include an illumination requirement value, a power density requirement value, an average illumination requirement value, etc., which are not limited in the present disclosure. The types of light sources to be arranged may include downlights, spotlights, ceiling lights, chandeliers, wall lights, etc.

[0039] In the disclosed embodiment, the number and arrangement positions of light sources in the area to be lit can be determined according to a certain light source arrangement mode based on the area type, area size, area shape, set illumination standard value, power density, average illumination, and parameters of light sources corresponding to the light source type, such as power, luminous intensity, etc. For example, the light source arrangement mode may include ring ceiling, single linear, multi-linear, etc.

[0040] In the embodiments of the present disclosure, the predicted illumination parameters may include predicted illumination values, predicted power density values, etc., which are not limited in the present disclosure. After determining the arrangement of the light sources in the area to be lit, the predicted illumination parameters of the working surface (reference plane) under the current arrangement can be calculated based on the position, power, luminous intensity of each light source in the area to be lit, and the area, height, luminous flux, etc. of the working surface (reference plane) in the area to be lit.

[0041] In the embodiments of the present disclosure, the standard values ​​of lighting parameters may include standard values ​​of illumination, standard values ​​of power density, etc., which are not limited in the present disclosure. After the predicted lighting parameters of the arrangement of the light sources are determined, the predicted lighting parameters can be compared with the standard values ​​of the lighting parameters. When the predicted lighting parameters meet the requirements of the standard values ​​of the lighting parameters, the position of the light source in the arrangement of the light sources corresponding to the predicted lighting parameters is determined as the target position. When the predicted lighting parameters do not meet the requirements of the standard values ​​of the lighting parameters, return to S101 and redetermine the initial position of one or more light sources in the area to be lit. For example, change the number and / or arrangement positions of the light sources. Then, continue to execute S102 and S103 until the predicted lighting parameters meet the requirements of the standard values ​​of the lighting parameters.

[0042] According to the embodiments of the present disclosure, the simulated arrangement of light sources in the area to be lit can be automatically completed according to the parameters of the area to be lit and the light sources, thereby improving the efficiency of light source arrangement when designing decoration plans and improving the ease of use and applicability of automatic light source arrangement.

[0043] Figure 21 is a flow chart of an automatic lighting arrangement method according to another embodiment of the present disclosure. The method may include one or more features of the automatic lighting arrangement method described above. In one embodiment, S101 determines the initial position of one or more light sources to be arranged in the area to be lit based on the area information, illumination requirements, and the type of light source to be arranged of the area to be lit, including:

[0044] S201, determining a lighting design style according to the area information, the illumination requirement and the type of light source to be arranged;

[0045] S202: Determine an initial position of the light source in the area to be lit according to the lighting design style.

[0046] In the embodiments of the present disclosure, the lighting design style may include a design with a main light source, a design without a main light source, etc., which is not limited in the present disclosure. A design with a main light source may include using a light source such as a chandelier or a ceiling lamp as the main light source, and other types of lamps such as downlights and spotlights as secondary light sources. A design without a main light source may include not arranging a main light source, and using lamps such as downlights and spotlights as secondary light sources.

[0047] In the disclosed embodiment, the lighting design style can be determined based on at least one of the area information, illumination requirements, and light source types. For example, if the area type in the area information is a corridor, the lighting design style can be determined as a design without a main light based on the corridor type. For another example, if the area type in the area information is a living room, the lighting design style can be determined as a design with a main light based on the living room type. For another example, when the light source types include chandeliers and downlights, the lighting design style can be determined as a design with a main light. In the disclosed embodiment, the number and arrangement of light sources can be determined based on different design styles, thereby obtaining the initial position of the light source.

[0048] According to the embodiments of the present disclosure, the design style of the light source can be selected based on the area type, illumination requirements and light source type, so that the system can determine the position of each light source according to the design style of the light source, thereby improving the efficiency of the light source arrangement.

[0049] In one embodiment, the light source includes a main light source and / or a secondary light source, and S202, determining an initial position of the light source in the area to be lit according to the lighting design style, includes at least one of the following:

[0050] In the case where the lighting design style is a main light source design and a main light source already exists in the area to be lighted, determining an initial position of the secondary light source to be arranged in the area to be lighted;

[0051] When the lighting design style is a main light source design and there is no main light source in the area to be lit, executing a main light source lighting algorithm to determine an initial position of the main light source;

[0052] In the case where the lighting design style is a design without a main light source, the initial position of the secondary light source to be arranged in the area to be lit is determined.

[0053] In the embodiment of the present disclosure, when the lighting design style is a main light source design, it is possible to detect whether there is a main light source in the area to be lit. In the case that there is no main light source in the area to be lit, the position of the main light can be determined according to the main light position calculation algorithm. Specifically, the illumination requirement value of the area to be lit is obtained, the central area of ​​the area to be lit is identified, the central area of ​​the area to be lit is divided into a plurality of lighting points, the main light source is separately arranged at each lighting point, and it is detected whether the current illumination meets the requirement, and the position that meets the illumination requirement value is used as the position of the main light source. For example, the central area of ​​the area to be lit is evenly divided into 1*2 rectangular sub-areas, and the vertices of each rectangle are used as lighting points, which are recorded as (1, 1), (1, 2), (1, 3), (2, 1), (2, 2), and (2, 3) in sequence. The main light sources are enumerated starting from the position (1, 1), and the illumination of the area when the main light source is arranged at each position is calculated, and the position that meets the illumination requirement value can be used as the position of the main light source.

[0054] In the embodiment of the present disclosure, when the lighting design style is a main light source design, if there is no need for other secondary light source designs, only the main light source can be arranged. The arrangement of the main light source can refer to the above example.

[0055] In the embodiment of the present disclosure, when the lighting design style is a design with a main light source, if there is a pre-placed main light source or a pre-determined main light source position, the step of calculating the main light position can also be skipped, and the main light source can be directly arranged using the pre-placed main light source or the pre-determined main light source position.

[0056] In the embodiments of the present disclosure, when the lighting design style is a design without a main light source, or when the design style is a design with a main light source and the position of the main light source has been determined, the position of the secondary light source can be determined according to the arrangement method, layout parameters, etc. corresponding to the lighting design style.

[0057] According to the embodiment of the present disclosure, the presence and arrangement of the main light source and the auxiliary light source can be determined based on the lighting design style, and then the initial position of the light source in the area to be lit can be obtained, which improves the efficiency of light source arrangement.

[0058] In one embodiment, determining the initial position of the secondary light source to be arranged in the area to be arranged includes:

[0059] Determine the arrangement of the secondary light sources to be arranged in the area to be arranged;

[0060] According to the arrangement mode and the arrangement parameters, the initial position of the secondary light source to be arranged in the area to be arranged is determined.

[0061] In the embodiment of the present disclosure, the arrangement mode may include single-line, multi-line, ring ceiling, etc., which is not limited in the present disclosure. The arrangement mode of the secondary light sources may be determined according to the lighting design style.

[0062] In the embodiment of the present disclosure, the arrangement parameters may include the distance of the light source from the wall, the regional illumination requirement, the regional size, the attributes in the light source related standards, etc., which are not limited in the present disclosure. The number and position of the secondary light sources in the current lighting area can be determined based on the arrangement mode and the arrangement parameters.

[0063] According to the embodiments of the present disclosure, the initial position of the light source can be determined in the area to be lit according to the arrangement method and the layout parameters, thereby improving the efficiency of the light source design.

[0064] In one embodiment, determining the arrangement of the secondary light sources to be arranged in the area to be arranged includes:

[0065] Select a preset arrangement corresponding to the lighting design style;

[0066] Or, get a custom arrangement.

[0067] In the disclosed embodiments, the arrangement method may include an arrangement method that has been set in advance for each lighting design style. For example, the candidate arrangement method for the auxiliary light source corresponding to the main light source design may be single-linear, multi-linear, etc. For another example, the candidate arrangement method for the auxiliary light source corresponding to the main light source design may be single-linear, multi-linear, ring ceiling, etc. An arrangement method may be selected from the candidate arrangement methods as the arrangement method for the auxiliary light sources in the area to be lit. It may be selected by the user, or it may be a default, or it may be automatically selected based on parameters such as the area type, or it may be randomly selected. The arrangement method may also include an arrangement method customized by the designer or the user. For example, after completing a lamp design, the designer may store the current arrangement method as a custom arrangement method, and may select the custom arrangement method when designing lamps for other apartment plans. One or more custom arrangement methods may be stored, and the designer or user may freely name the custom arrangement method.

[0068] According to the embodiment of the present disclosure, the arrangement of light sources can be obtained, which facilitates the determination of the positions of light sources in the area to be lit.

[0069] In one embodiment, determining the initial position of the secondary light source to be arranged in the area to be arranged according to the arrangement mode and the arrangement parameters includes:

[0070] Determine the number of the secondary light sources according to at least one of the illumination requirement, the light source utilization coefficient, the maintenance coefficient in the arrangement parameters of the secondary light sources, the work surface area in the area information, and the attributes of the secondary light sources;

[0071] The initial position of the auxiliary light source is determined according to at least one of the number of the auxiliary light sources, the spacing in the arrangement, the distance from the wall, and the area size in the area information.

[0072] In the embodiment of the present disclosure, the illumination may be the energy of visible light received per unit area of ​​the working surface (reference plane), and an optional calculation formula is as follows:

[0073] E=dΦ / dA Formula 1

[0074] Wherein, dΦ can represent the luminous flux incident on the working surface (reference plane) containing the point, and the luminous flux can be the light energy radiated by the light source per unit time, and its unit is lumen. dA can represent the area of ​​the working surface (reference plane), and E can represent the illuminance, and its unit is lux (lx).

[0075] In the disclosed embodiment, the light source utilization coefficient may be the ratio of the luminous flux received directly or through mutual reflection to the sum of the rated luminous flux emitted by all light sources on the working surface or other specified reference plane. An optional calculation formula is as follows:

[0076] Cu=Fu / F0 Formula 2

[0077] F=(E n ×dA) / (N×Cu×K) Formula 3

[0078] Where Cu is the light source utilization coefficient, Fu is the useful luminous flux, which can be calculated based on the direct luminous flux and the reflected luminous flux. F0 is the total luminous flux emitted from the light source. F is the luminous flux of a single light source, and E is the total luminous flux emitted from the light source. n It can be the illumination requirement, which can include the average illumination value of the working condition specified by the lighting standard. dA can be the area of ​​the working surface (reference plane). N can be the number of arranged light sources, and K can be the maintenance factor, which can represent the ratio of the average illumination or average brightness on the working surface (reference plane) after the light source has been used for a certain period of time to the average illumination or average brightness obtained on the same working surface (reference plane) when the device is newly installed under the same conditions. Among them, Cu and K can be found based on relevant standards.

[0079] In the disclosed embodiment, the room index (RI) may be calculated first. The room index may represent the geometric shape of the room. An optional calculation formula is as follows:

[0080] RI=(l×w) / [h×(l+w)]Formula 4

[0081] Among them, l can be the length of the area to be lit, w can be the width of the area to be lit, and h can be the distance between the light source and the working surface (reference plane), which can be calculated based on the difference between the light source setting height and the working surface (reference plane) height. After obtaining the room type index, the room type index and reflectivity can be used to query and obtain the lamp utilization coefficient. The reflectivity can represent the reflectivity of the walls, ceilings and floors of the space, and can be obtained based on the material of the apartment plan. For example, a room is 19.2m long and 12.8m wide, the lamp installation height is 2.6m, and the working surface height is 0.75m. Then, the room area is calculated to be 245.76m 2 , the room index is calculated to be 4.15. The reflectivity of the current room is obtained as 70% for the wall, 50% for the ceiling, and 20% for the floor. The utilization coefficient table is queried and the utilization coefficient value of the room index 4.15 is calculated to be 1.005. An example of a utilization coefficient table is shown in Table 1 below.

[0082] Table 1 Utilization coefficient table

[0083]

[0084]

[0085] In the embodiments of the present disclosure, the properties of the light source may include the luminous intensity, power, color temperature, type, etc. of the light source, which is not limited in the present disclosure. Based on the arrangement mode, the number of secondary light sources that can meet the illuminance requirement can be calculated according to the illuminance requirement, light source utilization factor, maintenance factor, work surface area, and luminous intensity, power, type, etc. of the secondary light sources in the current arrangement parameters. An optional calculation formula is as follows:

[0086] L n =(E n ×dA) / (F×Cu×K) Formula 5

[0087] Among them, L n can be the number of lamps, E n It can be the illumination requirement, and can also be called the target average illumination of the working surface (reference plane). dA can be the area of ​​the working surface (reference plane), F can be the luminous flux of a single light source, Cu can be the light source utilization coefficient, and K can be the maintenance coefficient.

[0088] In the disclosed embodiment, the position of the secondary light source can be calculated based on one or more of the calculated number of secondary light sources, the spacing between light sources in the arrangement parameters, the distance from the wall, and the area size, so as to obtain the position of the light sources that meet the illumination requirements and are evenly arranged in an arrangement manner, and obtain the initial position of the secondary light source.

[0089] In the embodiment of the present disclosure, when there is a main light source design, after the positions of the main light source and the auxiliary light source are determined respectively, the two can be combined to obtain the initial position of the light source. When there is no main light source design, the initial position of the auxiliary light source can be used as the initial position of the light source.

[0090] According to the embodiments of the present disclosure, the initial position of the light source can be determined based on the arrangement mode and the layout parameters, without the need for the user to manually set the light source, thereby improving the efficiency of lamp design.

[0091] Figure 3 is a flow chart of an automatic lighting arrangement method according to another embodiment of the present disclosure. The method may include one or more features of the automatic lighting arrangement method described above. In one embodiment, S102 determines the predicted lighting parameters in the area to be lit according to the initial position of the one or more light sources in the area to be lit, including:

[0092] S301, querying the scene illumination configuration table according to the type of the area to be lit to obtain the working surface of the area to be lit;

[0093] S302, dividing the working surface into grids to obtain grid points, and calculating the illumination of all the grid points according to the initial positions of the light sources;

[0094] S303: Calculate the average illumination and illumination uniformity of the reference plane according to the illumination of all grid points to obtain the predicted illumination parameters.

[0095] In the embodiment of the present disclosure, the scene illumination configuration table may include illumination standard values ​​corresponding to different area types, heights of work surfaces (reference planes), general color rendering indexes, etc. After obtaining the type of the area to be lit in the apartment plan, the corresponding illumination standard value, height of the work surface (reference plane), general color rendering index, etc. may be queried based on the type of the area to be lit.

[0096] In the embodiment of the present disclosure, after obtaining the working surface (reference plane), the working surface (reference plane) can be grid-divided according to a certain ratio to obtain grid division lines, and then the intersection of the grid division lines is used as the grid point. The illumination value of each grid point under the initial position condition of the current light source can be calculated. The calculation method can refer to the above formula 1.

[0097] In the embodiment of the present disclosure, after the illumination values ​​of all grid points are obtained, the average illumination value of the reference plane can be calculated based on the sum of the illumination values ​​of the grid points and the number of grid points. An optional calculation formula is as follows:

[0098]

[0099] Among them, E avg Can be the average illumination value, E i It can be the illumination value of different grid points, and n can be the total number of grid points.

[0100] In the embodiment of the present disclosure, after obtaining the average illumination value of the reference plane, the illumination uniformity of the reference plane can be calculated based on the average illumination value and the minimum illumination value. An optional calculation formula is as follows:

[0101] U0=E min / E avg Formula 7

[0102] Among them, U0 is the illumination uniformity, E min It can be the minimum illuminance value among the grid point illuminance values.

[0103] According to the embodiments of the present disclosure, the predicted illumination parameter value at the initial position of the light source can be calculated, which provides a judgment basis for determining the target position of the light source.

[0104] Figure 4 1 is a flow chart of an automatic lighting arrangement method according to another embodiment of the present disclosure. The method may include one or more features of the automatic lighting arrangement method described above. In one embodiment, S103 compares the predicted lighting parameters in the area to be lit with the standard values ​​of the lighting parameters to determine the target positions of the one or more light sources to be arranged, including:

[0105] S401, querying the scene illumination configuration table to obtain the standard value of the lighting parameter according to the type of the area to be lit, and comparing the standard value of the lighting parameter with the predicted lighting parameter;

[0106] S402: if the predicted illumination parameter does not meet the illumination parameter standard value, re-determine the initial position of the light source;

[0107] S403: When the predicted illumination parameter meets the illumination parameter standard value, output the current initial position of the light source as the target position of the light source.

[0108] In the embodiment of the present disclosure, the illumination parameter standard value may include an average illumination standard value and / or an illumination uniformity standard value. The average illumination value in the predicted illumination parameter and the average illumination standard value in the illumination parameter standard value may be compared to obtain a comparison result. And / or, the illumination uniformity in the predicted illumination parameter and the illumination uniformity standard value in the illumination parameter standard value may be compared to obtain a comparison result.

[0109] In the disclosed embodiment, the comparison result may include that the predicted lighting parameters meet the standard values ​​of the lighting parameters or that the predicted lighting parameters do not meet the standard values ​​of the lighting parameters. In the case where the predicted lighting parameters do not meet the standard values ​​of the lighting parameters, it is necessary to re-execute the aforementioned step S101 to re-determine the initial position of the light source. In the case where the predicted lighting parameters meet the standard values ​​of the lighting parameters, the initial position of the current light source can be used as the target position of the light source.

[0110] In the disclosed embodiment, light source design and effect rendering can be performed in the apartment plan according to the obtained target position of the light source to present the effect after the light source arrangement.

[0111] According to the disclosed embodiments, the arrangement of light sources can be screened through the scene illumination configuration table to obtain an arrangement result that meets the requirements, thereby improving the availability of the light source arrangement and improving the efficiency of light source design.

[0112] In one embodiment, the method further comprises:

[0113] The area is divided according to the apartment plan to obtain the area to be lit, and the area parameters of the area to be lit are obtained.

[0114] In one embodiment, the method further comprises:

[0115] Perform regional division according to the lighting plan to obtain the area to be lit, and set regional parameters of the area to be lit.

[0116] In the disclosed embodiments, the apartment plan may include an apartment diagram, a design drawing, and the like. Based on an area division algorithm, the apartment plan may be divided into a plurality of areas to be lit, and the shapes of the areas to be lit may include a variety of shapes, such as rectangles, triangles, trapezoids, or other irregular shapes. And the type of the area to be lit is determined according to the markers or area features in the apartment plan. The markers may include other items that have been arranged in the area to be lit, such as a sofa, a television, a bed, a cabinet, and the like. The area features may include the type of adjacent areas of the current area, the location of the current area, the shape of the current area, and the like. The area parameters of the area to be lit may include the type, length, width, and the like.

[0117] In one application scenario, taking the apartment plan including the living-dining room area as an example, the area division can be performed according to the following steps:

[0118] 1. The order of determining the area types in the apartment plan can be: living room - corridor - dining room - entrance - corridor;

[0119] 2. Use the TV and sofa orientation and adjacent walls to find the living room; if the sofa is not against the wall, set up a virtual sofa wall based on the sofa position;

[0120] 3. Find the long corridor area based on the slope and length of the side of the apartment in the apartment plan excluding the living room area;

[0121] 4. After finding the living room and corridor, find the largest inscribed rectangle in the remaining area, which must include the dining table and be a long strip with a not-too-extreme aspect ratio, to determine the dining room area;

[0122] 5. Look for the entrance area in the remaining area. The entrance area may overlap with the living room or dining room so it may not exist;

[0123] 6. For the remaining scattered areas that have not been divided or select the polygon with the largest area, find the largest inscribed rectangle and fill it as the corridor area.

[0124] In the disclosed embodiment, the apartment plan may also be divided into areas based on a pre-designed lighting plan to obtain areas to be lit.

[0125] According to the embodiments of the present disclosure, the area to be lit can be divided according to the apartment plan, and various parameters of the area to be lit can be obtained, providing a basis for subsequent automatic lighting.
