[0032] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0033] Figure 1 A schematic diagram showing a lighting coverage method for a display scene Figure 1 .

[0034] See also Figure 1 In a first aspect, an embodiment of the present application provides a method for lighting coverage of a display scene, the method comprising: operation 101, determining a display area and a visiting area adjacent to the display area; operation 102, determining a first installation coordinate of a first lighting device based on the display area and the visiting area; operation 103, adjusting a first optical axis of the first lighting device based on the first installation coordinate, and when the adjustment is such that a first edge line corresponding to the first optical axis is located in a first area above the display area, a center line of the first optical axis is located in the display area, and a second edge line corresponding to the first optical axis is located in the visiting area, determining corresponding optical axis deflection information; operation 104, installing the first lighting device based on the first installation coordinate and the optical axis deflection information.

[0035] An embodiment of the present application provides a lighting coverage method for a display scene. According to the display area and the visiting area, a first installation coordinate and corresponding optical axis deflection information of a first lighting device are determined, and the first lighting device is installed based on the first installation coordinate and the optical axis deflection information, so that the light of the first lighting device can be accurately irradiated to the display area, thereby realizing precise lighting of the display area, and reducing the amount of light directly irradiated to the visiting area, thereby reducing the discomfort of visitors caused by direct light, and meeting the illumination difference between the display area and the visiting area.

[0036] In operation 101 of the embodiment of the present application, the display area can form a facade with the visiting area. The display area is for displaying exhibits, and the exhibits can be three-dimensional exhibits, such as vegetables, fruits, goods, ornaments, etc., or flat exhibits, such as hanging paintings, calligraphy, etc. The visiting area can be an area for visitors to walk and stay, for example, a visiting aisle, a visiting gallery, etc. In a specific implementation scenario, when the visiting area is a visiting gallery, the display area can be at least one of a display surface of a shelf for placing goods, a wall area for hanging decorative paintings, and a display area of ​​a display rack for displaying exhibits.

[0037] In operation 102 of the embodiment of the present application, the first installation coordinates of the first lighting device can be determined based on the relative position information of the display area and the visiting area. The relative position information includes but is not limited to at least one of the height, length and width of the display area, the height, length and width of the visiting area, the angle, relative height, relative size, etc. between the visiting area and the display area. The embodiment of the present application does not limit the device type, lighting color and shape of the first lighting device. The first lighting device can be any one of a track light, a chandelier, a spotlight, a grille light, a fluorescent light, a panel light, a hidden LED light or other lamps. The first installation coordinates are used to determine the installation position of the first lighting device. In a specific implementation scenario, the first installation coordinates correspond to the center position of the light source of the first lighting device.

[0038] In operation 103 of the embodiment of the present application, the first optical axis of the first lighting device is adjusted to meet the lighting coverage requirements of the display area and the visiting area, and to meet the difference requirements of the contrast, so that the light of the first lighting device can accurately illuminate the display area, and the light irradiated to the visiting area will not directly hit the visitors' sight, thereby ensuring the comfort of visitors during the visit. The first optical axis is used to represent a straight line that passes through the light source of the first lighting device and is perpendicular to the plane where the light outlet of the first lighting device is located. The lighting range of the first lighting device irradiating the display area can be changed by adjusting the first optical axis, and the adjustment method of the first optical axis can be angle adjustment.

[0039] In operation 103 of the embodiment of the present application, the first edge line corresponding to the first optical axis is the highest lighting edge line in the lighting range corresponding to the first lighting device. The first area is located above the display area and does not overlap with the display area. The first area can be connected to the display area or not. Correspondingly, the second edge line corresponding to the first optical axis is the lowest lighting edge line in the lighting range corresponding to the first lighting device. By adjusting the first edge line corresponding to the first optical axis to the first area above the display area, adjusting the center line of the first optical axis to the display area, and adjusting the second edge line corresponding to the first optical axis to the visiting area, the main lighting range of the first lighting device can cover the display area, and the edge lighting range of the first lighting device can provide lighting for the visiting area, that is, it can meet the lighting requirements of the visiting area, and avoid excessive lighting in the visiting area, and meet the difference requirements of the illumination of the irradiated surface between the visiting area and the display area.

[0040] Among them, the edge line is used to characterize the dividing line between the illuminated area and the non-illuminated area, and is used to define the effective coverage of the lighting. According to actual needs, the edge line can be determined according to the threshold of the lighting intensity, such as defining the position where the lighting intensity drops to a specific percentage of the maximum intensity as the edge line. For example, in one implementation scenario, the position where the lighting intensity drops to 10% of the maximum intensity is defined as the edge line. In an embodiment of the present application, the position corresponding to the specific percentage of the edge line can be any value between 0 and 50%, and the specific percentages of the first edge line and the second edge line can be the same or different.

[0041] In one implementation scenario, the deflection adjustment of the first lighting device can be implemented in combination with the basic illumination formula, and the basic illumination formula is: Where I is the light intensity and d is the distance. Considering the incident angle of the light, the cosine law is introduced, that is, the illumination is related to the cosine of the incident angle of the light, that is, θ is the angle between the light ray and the centerline of the optical axis.

[0042] The facade of the display area far away from the light source needs to rely on the light beam of the center line of the optical axis. The directional deflection lighting device can ensure that the light flux is focused on the display area, so that the center line of the optical axis falls on the lower half of the display area, ensuring uniform illumination of the shelf facade.

[0043] It should be understood that operations 101 to 103 of the present application may be performed through simulation processing or on-site processing in an actual environment.

[0044] In operation 104 of the embodiment of the present application, after determining the first installation coordinates and the optical axis deflection information, the first lighting device can be installed according to the first installation coordinates and the optical axis deflection information to achieve lighting coverage of the display scene in the actual scene.

[0045] Figure 2 A schematic diagram showing a lighting coverage method for a display scene Figure 2 ;

[0046] See also Figure 2 In one embodiment, operation 102 includes: operation 1021, determining a first upper height limit value corresponding to the visiting area and a second upper height limit value corresponding to the display area; operation 1022, determining a target installation height of the first lighting device based on the first upper height limit value and the second upper height limit value; operation 1023, determining a target installation distance of the first lighting device corresponding to the display area based on the display range of the display area and the visiting range of the visiting area; operation 1024, determining a first installation coordinate based on the target installation height and the target installation distance.

[0047] The first installation coordinates of the embodiment of the present application include a target installation height and a target installation distance. Operation 1022 includes: first, determining a first ratio of the first height upper limit value to the second height upper limit value; then, determining a second ratio range of the second height upper limit value based on the first ratio; and then, determining a target installation height of the first lighting device and a corresponding type of the first lighting device based on the second ratio range and the first height upper limit value.

[0048] Specifically, the target installation height of the first lighting device can be determined according to the first upper limit of the height of the visiting area and the second upper limit of the height of the display area. The embodiment of the present application is applicable to the implementation scenario where the ratio of the first upper limit of the height of the visiting area to the second upper limit of the height of the display area is higher than 1.3:1. For example, when the second upper limit of the height of the display area is 2 meters, the first upper limit of the height of the visiting area in the embodiment of the present application is not less than 2.6 meters.

[0049] In a specific implementation scenario, the height ratio range of the target installation height of the first lighting device to the second upper limit of the height of the display area is (1.3-1.5): 1. Based on the first upper limit of the height of the visiting area and the height ratio range of the first lighting device to the display area, the present application can adaptively select different types of lighting devices to meet lighting needs.

[0050] For example, in a specific implementation scenario, the top height of the visiting area is 2.7 meters and the top height of the display area is 2 meters. In this case, track lights and / or ceiling lights can be selected as the first lighting device. In another implementation scenario, the top height of the visiting area is 3.5 meters and the top height of the display area is 2 meters. In this case, a chandelier can be selected as the first lighting device.

[0051] In operation 1023, the display range of the display area can be characterized by the distance between the highest position of the display area and the height from the ground and the distance in the extension direction thereof, and the visiting range of the visiting area can be characterized by the distance between the visiting area and the display area in the extension direction thereof. For example, the display area is characterized as follows: the height of the display facade is 2 meters and the length is 2 meters; the visiting area is characterized as follows: the width of the visiting aisle is 2.06 meters and the length is 2 meters.

[0052] In a specific implementation scenario, the maximum value of the target installation distance does not exceed the maximum distance between the visiting area and the display area.

[0053] In another specific implementation scenario, when there are asymmetric display areas on both sides of the visiting area, the width of the visiting area can be divided based on the height ratio of the two display areas to determine the target installation distance. For example, the first display area is 1 meter above the ground, the second display area is 2 meters above the ground, and the visiting area is 1.5 meters wide. The target installation distance can be set at 0.5 meters away from the first display area and 1 meter away from the second display area.

[0054] In one possible implementation, operation 1023 includes: first, if there are two display areas and they are located on both sides of the same visiting area, the first lighting device is set at the center of the visiting area so that the target installation distance between the first lighting device and the two display areas is equal; the method also includes: setting the first lighting device to at least two optical axes so that the at least two optical axes are respectively directed toward the corresponding display areas according to the corresponding optical axis deflection information.

[0055] Display areas can be set on both sides of the visiting area. Correspondingly, the first lighting device can include at least two light sources. The optical axes of the two light sources can be deflected to the two display areas respectively. According to the actual conditions of the display areas, the target deflection information of the optical axes of the two light sources can be the same or different. In the case where symmetrical display areas are set on both sides of the visiting area, the target installation distance can be set in the middle of the visiting area. One of the light sources is used to provide lighting to the display area on one side, and the other light source is used to provide lighting to the display area on the other side. In the embodiment of the present application, the same light source may include multiple lamp beads, lamp bodies and / or light strips. The same light source in the embodiment of the present application is used to represent all lamp beads, lamp bodies and / or light strips with parallel optical axis center lines in the same lighting device.

[0056] In operation 1024 of the embodiment of the present application, if the range of the display area and the visiting area does not exceed the lighting range of the first lighting device, when the target installation height and the target installation distance are known, the coordinates of the first lighting device in the extension direction of the display area can correspond to the center of the display area. If the range of the display area and the visiting area exceeds the lighting range of the first lighting device, when the target installation height and the target installation distance are known, other lighting devices can be added equidistantly relative to the first lighting device in the extension direction of the display area to meet the lighting coverage of the display area. The distance to which other lighting devices are added is determined based on the lighting range or target standard. For example, if the standard for a certain area is that the spacing between lighting devices is not less than 2 meters, the spacing between other lighting devices is increased to be not less than 2 meters.

[0057] Figure 3 A schematic diagram showing a lighting coverage method for a display scene Figure 3 ;

[0058] See also Figure 3 In one embodiment, operation 103 includes: operation 1031, if the display area is set in a three-dimensional display structure, determine the top surface area of ​​the three-dimensional display structure; operation 1032, determine a first direction perpendicular to the display area based on the top surface area; operation 1033, determine a first area within the top surface area along the first direction, and the first area is adjacent to the display area; operation 1034, adjust the first edge line corresponding to the first optical axis to be located within the first area.

[0059] In a specific implementation scenario, the exhibits are usually three-dimensional structures and need to be placed in a three-dimensional display structure, such as a display cabinet, a display case, a wardrobe, a shelf, a shelf, a storage rack, a display box, etc. Such three-dimensional display structures all have a top surface area. In order to ensure lighting coverage, it is necessary to determine the top surface area of ​​the three-dimensional display structure, and make the lighting range cover the top surface area to ensure that the entire display area of ​​the three-dimensional display structure can be covered by the lighting range. The first area can be determined in the top surface area and adjacent to the display area, thereby ensuring lighting coverage of the display area.

[0060] In one possible implementation, if the three-dimensional display structure has double-sided display areas, the top surface area is divided so that the first areas corresponding to each display area do not overlap with each other.

[0061] In one feasible scenario, the three-dimensional display structure has a double-sided display area, and the double-sided display area is spaced apart from the viewing area, such as a supermarket shelf, where each aisle has shelves on both sides, and items can be placed on both sides of the shelf between the two aisles. In this implementation scenario, it is necessary to divide the top surface area of ​​the display structure so that the first areas corresponding to the two display areas do not overlap each other. In this way, when adjusting the optical axis, the edge lines of the lighting devices used to illuminate the two display areas do not overlap each other, thereby avoiding overlapping lighting fixtures in the top surface area, avoiding light overflow to another display area and the viewing area of ​​another display area, and improving lighting utilization while accurately covering the entire display area.

[0062] In one possible implementation, operation 103 includes: operation 1035, determining the center position of the display area, and determining the lower display half of the display area based on the center position; operation 1036, adjusting the center line of the first optical axis to be located in the lower display half.

[0063] In a specific implementation scenario, on a parallel plane parallel to the light-emitting surface, the light intensity of the center line of the optical axis is generally higher than the light intensity of the edge line of the optical axis, and the farther away from the light-emitting surface, the lower the light intensity. Therefore, the embodiment of the present application can preliminarily balance the illumination of the upper half and the lower half of the display by adjusting the center line of the first optical axis to be located in the lower half of the display, thereby achieving illumination balance relative to the display area.

[0064] In one possible implementation, operation 103 further includes: operation 1037, determining the orthographic projection coordinates of the viewing area corresponding to the first installation coordinates; and operation 1038, adjusting the second edge line corresponding to the first optical axis to be within the projection range corresponding to the projection coordinates.

[0065] In operation 1038, the projection range is used to characterize the target range formed by the projection coordinates. In one implementation scenario, the projection range is the projection coordinates. The projection range can be determined based on various errors and / or errors such as installation error, simulation error, manual error, standard allowable deviation, etc. By adjusting the second edge line to the projection range, in a scenario where there are display areas on both sides of the viewing area, the viewing area can be fully covered by lighting, and the lighting does not overlap, thereby improving energy utilization.

[0066] It should be understood that the markings of operations 1031 to 1038 in the present application are only used to distinguish the operation steps, and the operation steps can be executed simultaneously or in a different order according to actual conditions.

[0067] Figure 4 A schematic diagram showing a lighting coverage method for a display scene Figure 3 ;

[0068] See also Figure 4In one embodiment, the method further includes: operation 201, determining a first dark area existing at the top of the display area in the extension direction; operation 202, adding a second lighting device and a corresponding second installation coordinate in the extension direction of the visiting area based on the first installation coordinate and the first dark area, so that the lighting range of the second lighting device covers the first dark area; wherein the second installation coordinate has the same target installation height and target installation distance as the first installation coordinate; operation 203, and so on, until there is no dark area in the display area, and stop adding lighting devices and corresponding installation coordinates.

[0069] In the implementation scenario where the range of the display area and the visiting area exceeds the lighting range of the first lighting device, since the lighting area is generally elliptical, the dark areas corresponding to the multiple lighting devices are mainly located in the extension direction of the top of the display area. Based on this, the embodiment of the present application first determines the first dark area existing in the extension direction of the top of the display area, and then adjusts the distance between the first lighting device and the second lighting device so that the lighting range of the second lighting device completely covers the first dark area, so that there is no dark area in the entire display area, meeting the requirement of complete lighting coverage of the display area.

[0070] It is understandable that in a scenario with multiple lighting devices, if the display ranges of display areas at different positions vary in the extension direction, and / or the widths of the visiting areas corresponding to display areas at different positions vary, the target installation height and target installation distance of each lighting device may also be determined in accordance with the method provided by the above-mentioned feasible scenario. If the display areas at different positions are the same in the extension direction, and the widths of the visiting areas corresponding to display areas at different positions are the same, the target installation height and target installation distance of each lighting device may remain unchanged.

[0071] In one embodiment, operation 202 includes: first, determining a first boundary coordinate based on the edge of the first dark area and the display area; then, deflecting the optical axis of the second lighting device based on the optical axis deflection information, and adjusting the coordinates of the second lighting device after the optical axis deflection; and then, when the third edge line of the second lighting device after the optical axis deflection is adjusted to cover the first boundary coordinate, determining the second installation coordinates of the second lighting device.

[0072] The first boundary coordinates are the edge intersection points of the first dark area, the corresponding display area and the first region, so as to meet the requirement that the first dark area can be completely covered when the lighting covers the first boundary coordinates.

[0073] Correspondingly, corresponding lighting devices can be added according to the actual range, size and extension direction of the visiting area and the display area, and the target installation coordinates and optical axis deflection information corresponding to each lighting device can be determined according to the above-mentioned implementable methods.

[0074] In one embodiment, the method also includes: first, determining the major axis and the minor axis of the first lighting device; then, making the minor axis perpendicular to the display area, and performing asymmetric light distribution on the first axis based on the display area; and then, making the major axis parallel to the display area, and performing symmetric light distribution on the second axis based on the visiting area.

[0075] After determining the target installation coordinates and optical axis deflection information of the first lighting device, the optical design of the optical elements of the first lighting device is used to achieve asymmetric light distribution processing on the short axis of the first lighting device, so as to achieve uniform illumination of the upper and lower halves of the display by the first lighting device. The optical design includes but is not limited to lens design, reflector design and / or other designs. Figure 5 As shown, the short-axis light of the first lighting device presents an asymmetric light distribution through optical design.

[0076] By optically designing the optical elements of the first lighting device, symmetrical light distribution processing on the long axis of the first lighting device is achieved. Figure 6 As shown, the long-axis light of the first lighting device presents symmetrical light distribution through optical design.

[0077] The first lighting device can provide uniform illumination to the visiting area and can illuminate the area in a wide angle, thereby achieving efficient use of the lighting device.

[0078] In one embodiment, the method also includes: first, obtaining target lighting information; determining a target lighting range of the first lighting device based on the target lighting information, the first edge line, the second edge line and the center line; and then determining a target model of the first lighting device based on the target lighting range.

[0079] It can be understood that, when the target installation coordinates and optical axis deflection information are determined, the target lighting range of the first lighting device can be roughly determined based on the positions of the first edge line, the second edge line and the center line. On this basis, a set of candidate models of lighting devices that meet the target lighting range can be obtained based on the target lighting range, and then the candidate model set can be screened according to the illumination requirements and intensity requirements of the lighting to determine the target model that meets the lighting coverage requirements.

[0081] See also Figure 7 To facilitate the overall understanding of the above-mentioned implementable scenarios, a specific implementation scenario is provided below for illustration.

[0082] In this specific implementation scenario, the overall scene is a supermarket with a floor height of 2.8 meters, the visiting area is an aisle with a width of 2.06 meters, the display area is a shelf with a height of 2 meters. The lighting device is an LED long track light, and the distance between the track lights is 3 meters.

[0083] The above parameters determine that the height of the first installation coordinate is 2.8 meters, set in the middle of the aisle, and the distance to the two shelves is equal. The optical axis deflection information is 26°. In conjunction with the optical design of the track light source, the center of gravity of the light spot is offset to ensure that the light flux is focused on the shelf area, so that the reflected light corresponding to the light source is asymmetrically distributed, and the light is accurately projected to the effective area of ​​the shelf facade with uniform illumination. Figure 8 As shown in the reference light intensity distribution diagram, it can be seen that the half-intensity beam angle in the short axis direction is 28°, so that the beam can cover half of the aisle and the top area of ​​the shelf. The long axis direction is parallel to the aisle direction, and symmetrical light distribution is adopted. The half-intensity beam angle is 105°, achieving continuous coverage of the light spot along the aisle direction, especially without dark area coverage on the top of the shelf irradiation surface.

[0086] An embodiment of the present application provides a lighting system for a display scene 100. According to a display area 200 and a visiting area 300, first installation coordinates and corresponding optical axis deflection information of a first lighting device 400 are determined. The display area 200 and the visiting area 300 are illuminated based on the first lighting device 400 installed at the first installation coordinates and the optical axis deflection information, so that light can be accurately irradiated to the display area 200, thereby achieving accurate lighting of the display area 200, and reducing the amount of light directly irradiated to the visiting area 300, thereby reducing the discomfort of visitors caused by direct light, and satisfying the illumination difference between the display area 200 and the visiting area 300.

[0087] In one possible implementation manner, the lighting device is at least one of a track light, a chandelier, a spotlight, a grille light, a fluorescent light, a panel light, and a hidden LED light.
