Description

[0002] Currently, in large supermarket lighting systems, to ensure that all items on the shelves are visible to customers, a sufficient, or even excessive, number of lights are typically installed vertically or at fixed angles to cover a wide area, meeting illuminance requirements. However, in supermarket settings, due to the height limitations of the light fixtures, the vertical light intensity can easily shine directly into customers' eyes, causing glare, affecting the shopping experience and visual perception of the goods. Furthermore, the light spills over to adjacent shelves and the ceiling, resulting in low energy efficiency and a significant waste of light energy. Summary of the Invention

[0032] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Figure 1 shows a flowchart of a lighting coverage method for a display scene.

[0034] Referring to Figure 1, a first aspect of this application provides a lighting coverage method for a display scene, the method comprising: operation 101, determining a display area and a visitor 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 visitor area; operation 103, adjusting a first optical axis of the first lighting device based on the first installation coordinate, and determining corresponding optical axis deflection information when the first edge line corresponding to the first optical axis is located in a first area above the display area, the center line of the first optical axis is located in the display area, and the second edge line corresponding to the first optical axis is located in the visitor area; operation 104, installing the first lighting device based on the first installation coordinate and the optical axis deflection information.

[0035] This application provides a lighting coverage method for a display scene. Based on the display area and the visitor area, the first installation coordinates and corresponding optical axis deflection information of the first lighting device are determined. The first lighting device is installed based on the first installation coordinates and optical axis deflection information, so that the light from the first lighting device can accurately illuminate the display area, thereby achieving precise lighting of the display area and reducing the amount of light directly shining into the visitor area, reducing discomfort to visitors caused by direct light, and meeting the illuminance difference between the display area and the visitor area.

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

[0037] In operation 102 of this application embodiment, the first installation coordinates of the first lighting device can be determined based on the relative position information of the display area and the visitor area. The relative position information includes, but is not limited to, at least one of the following: the height, length, and width of the display area; the height, length, and width of the visitor area; and the angle, relative height, and relative dimensions between the visitor area and the display area. This application embodiment does not limit the device type, lighting color, or shape of the first lighting device; the first lighting device can be any of the following: track light, chandelier, spotlight, grille light, fluorescent light, panel light, concealed LED light, or other lighting fixtures. The first installation coordinates are used to determine the installation position of the first lighting device. In one 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 this embodiment, the first optical axis of the first lighting device is adjusted to meet the lighting coverage requirements of the display area and the visitor area, as well as the difference in illuminance. This ensures that the light from the first lighting device accurately illuminates the display area and prevents the light illuminating the visitor area from directly hitting the visitor's line of sight, thus guaranteeing visitor comfort during the visit. The first optical axis represents a straight line passing through the location of the light source of the first lighting device and perpendicular to the plane where the light outlet of the first lighting device is located. Adjusting the first optical axis can change the lighting range of the display area illuminated by the first lighting device. The adjustment method for the first optical axis can be angle adjustment.

[0039] In operation 103 of this application embodiment, 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 region is located above the display area and does not overlap with the display area; the first region may or may not be connected to the display area. 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 region located 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 viewing 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 viewing area. This satisfies the lighting requirements of the viewing area while avoiding excessive lighting in the viewing area, thus meeting the difference in illuminance between the viewing area and the display area.

[0040] The edge line is used to characterize the boundary between the illuminated and unilluminated areas, defining the effective coverage of the lighting. Depending on actual needs, the edge line can be determined based on a threshold of 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 this embodiment, the specific percentage position corresponding to 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 of the first lighting device can be adjusted by combining the basic illuminance formula, which is: ,in, It is light intensity. It's about distance. Considering the angle of incidence of light, we introduce the cosine rule, which states that illuminance is related to the cosine of the angle of incidence of light. = θ is the angle between the ray and the center line of the optical axis.

[0042] For display areas that are far from the light source, the light beams on the display surface need to rely on the center line of the light axis. Directional deflection lighting devices can ensure that the light flux is focused on the display area, so that the center line of the light axis falls on the lower half of the display area, thus ensuring uniform illumination on the shelf facade.

[0043] It should be understood that operations 101 to 103 of this application can be performed through simulation or in a real-world environment.

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

[0045] Figure 2 shows a flowchart of a lighting coverage method for a display scene;

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

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

[0048] Specifically, the target installation height of the first lighting device can be determined based on the first upper limit of the visitor area and the second upper limit of the display area. This application embodiment is applicable to implementation scenarios where the ratio of the first upper limit of the visitor area to the second upper limit of the display area is greater than 1.3:1. For example, when the second upper limit of the display area is 2 meters, the first upper limit of the visitor area in this application embodiment is not less than 2.6 meters.

[0049] In one specific implementation scenario, the ratio of the target installation height of the first lighting device to the upper limit of the second height of the display area is in the range of (1.3~1.5):1. Based on the upper limit of the first height of the visitor area and the range of the height ratio between the first lighting device and the display area, this application can adaptably select different types of lighting devices to meet lighting needs.

[0050] For example, in one specific implementation scenario, the ceiling height of the visitor area is 2.7 meters and the ceiling height of the display area is 2 meters. In this case, track lighting and / or ceiling lights can be selected as the primary lighting devices. In another implementation scenario, the ceiling height of the visitor area is 3.5 meters and the ceiling height of the display area is 2 meters. In this case, pendant lights can be selected as the primary lighting devices.

[0051] In Operation 1023, the display area can be characterized by the distance between the highest point of the display area and its height above the ground, as well as the distance in its extending direction. The visitor area can be characterized by the distance between the visitor area and the display area in its extending direction. For example, the display area can be characterized as: the height of the display facade is 2 meters and the length is 2 meters; the visitor area can be characterized as: the width of the visitor aisle is 2.06 meters and the length is 2 meters.

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

[0053] In another specific implementation scenario, where there are asymmetrical display areas on both sides of the visitor area, the width of the visitor area can be divided based on the height ratio of the two display areas to determine the target installation distance. For example, if the first display area is 1 meter above the ground, the second display area is 2 meters above the ground, and the visitor 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 first display area.

[0054] In one possible implementation, operation 1023 includes: first, if there are two display areas located on opposite sides of the same visitor area, a first lighting device is placed at the center of the visitor area, such that the first lighting device is equidistant from the target installation distance of the two display areas; the method further includes: setting the first lighting device to at least two optical axes, such that the at least two optical axes are respectively directed toward the corresponding display area according to the corresponding optical axis deflection information.

[0055] Display areas can be set up on both sides of the viewing area. Correspondingly, the first lighting device can include at least two light sources, and the optical axes of the two light sources can be deflected towards the two display areas respectively. Depending on the actual situation of the display areas, the target deflection information of the optical axes of the two light sources can be the same or different. When there are symmetrical display areas on both sides of the viewing area, the target installation distance can be set at the middle of the viewing area. One light source is used to provide illumination to the display area on one side, and the other light source is used to provide illumination to the display area on the other side. In the embodiments of this application, the same light source can include multiple lamp beads, lamp bodies, and / or light strips. The same light source in the embodiments of this 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 this application embodiment, if the range of the display area and the visitor area does not exceed the illumination range of the first lighting device, and given the known target installation height and target installation distance, 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 visitor area exceeds the illumination range of the first lighting device, and given the known target installation height and target installation distance, other lighting devices can be added at equal intervals relative to the first lighting device in the extension direction of the display area to meet the illumination coverage of the display area. The distance between the added other lighting devices is determined based on the illumination 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, then the spacing between the added other lighting devices will not be less than 2 meters.

[0057] Figure 3 shows a flowchart of a lighting coverage method for a display scene;

[0058] Referring to Figure 3, in one possible implementation, operation 103 includes: operation 1031, if the display area is set in a three-dimensional display structure, determining the top surface area of ​​the three-dimensional display structure; operation 1032, determining a first direction perpendicular to the display area based on the top surface area; operation 1033, determining a first area in the top surface area along the first direction, the first area being adjacent to the display area; operation 1034, adjusting so that the first edge line corresponding to the first optical axis is located in the first area.

[0059] In a specific implementation scenario, the displayed items are typically three-dimensional structures that need to be placed within a three-dimensional display structure, such as display cases, cabinets, wardrobes, shelves, racks, storage racks, and display boxes. These three-dimensional display structures all have a top surface area. To ensure lighting coverage, it is necessary to define the top surface area of ​​the three-dimensional display structure and ensure that the lighting range covers this area, thus guaranteeing that the entire display area is illuminated. A first area can be defined within 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 a double-sided display area, the top surface area is divided so that the first area corresponding to each display area does not overlap.

[0061] In one feasible scenario, the three-dimensional display structure has double-sided display areas, which are spaced apart from the viewing area. For example, in a supermarket, each aisle has shelves on both sides, and items can be placed on both sides of the shelves located between the two aisles. In this scenario, the top area of ​​the display structure needs to be divided so that the first areas corresponding to the two display areas do not overlap. This design ensures that when adjusting the light axis, the edges of the lighting fixtures used to illuminate the two display areas do not overlap, thus preventing overlapping illumination from the lighting fixtures in the top area and preventing light from spilling into the other display area and its viewing area. This improves lighting utilization while ensuring accurate coverage of 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 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 half of the display area.

[0063] In one specific implementation scenario, on a parallel surface parallel to the light-emitting surface, the light intensity of the center line of the optical axis is usually higher than that of the edge line of the optical axis, and the light intensity is lower the further away from the light-emitting surface. Therefore, the embodiments of this application can initially balance the illuminance of the upper and lower half of the display area by adjusting the center line of the first optical axis to be located in the lower half of the display area, thereby achieving relative illuminance balance of the display area.

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

[0065] In operation 1038, the projection range is used to characterize the target area formed by the projection coordinates. In one implementation scenario, the projection range is the same as the projection coordinates. The projection range can be determined based on various errors and / or tolerances, such as installation errors, simulation errors, human errors, and standard allowable deviations. By adjusting the second edge line to the projection range, in scenarios where there are display areas on both sides of the visitor area, the visitor area can achieve full lighting coverage without overlapping lighting, thus improving energy efficiency.

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

[0067] Figure 4 shows a flowchart of a lighting coverage method for a display scene.

[0068] Referring to Figure 4, in 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 based on the first installation coordinate and the first dark area in the extension direction of the visitor area, so that the lighting range of the second lighting device covers the first dark area; wherein, the target installation height and target installation distance of the second installation coordinate are the same as those of the first installation coordinate; operation 203, and so on, until there is no dark area in the display area, and then stopping the addition of lighting devices and corresponding installation coordinates.

[0069] In implementation scenarios where the display area and visitor area exceed the illumination range of the first lighting device, since the illumination area is typically elliptical, the dark areas corresponding to multiple lighting devices are mainly located along the extension direction of the top of the display area. Based on this, the embodiments of this application first determine the first dark area existing in the extension direction at the top of the display area, and then adjust the distance between the first lighting device and the second lighting device so that the illumination range of the second lighting device completely covers the first dark area, thereby eliminating dark areas within the entire display area and meeting the requirement of complete illumination coverage for the display area.

[0070] It is understandable that in scenarios with multiple lighting installations, if the display area varies at different locations along the extension direction, and / or the width of the viewing area varies for each display area, the target installation height and target installation distance for each lighting installation can be determined in accordance with the methods provided in the aforementioned feasible scenarios. If the display areas at different locations are identical along the extension direction, and the width of the viewing area for each display area is consistent, then the target installation height and target installation distance for each lighting installation can remain unchanged.

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

[0072] The first boundary coordinate is the intersection of the first dark area, the corresponding display area, and the first area, thus satisfying the requirement that the first dark area can be completely covered when the lighting covers the first boundary coordinate.

[0073] Correspondingly, 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 of each lighting device can be determined according to the above-mentioned feasible implementation method.

[0074] In one embodiment, the method further includes: first, determining the major axis and minor axis of the first lighting device; then, making the minor axis perpendicular to the display area and performing asymmetrical light distribution processing on the first axis based on the display area; and finally, making the major axis parallel to the display area and performing symmetrical light distribution processing on the second axis based on the visitor area.

[0075] After determining the target installation coordinates and optical axis deflection information of the first lighting device, asymmetric light distribution processing of the short axis of the first lighting device is achieved through optical design of the optical elements of the first lighting device, thereby achieving uniform illuminance for the upper and lower halves of the display area. The optical design includes, but is not limited to, lens design, reflector design, and / or other designs. As shown in Figure 5, the optical design enables the short axis light of the first lighting device to exhibit asymmetric light distribution.

[0076] By designing the optical elements of the first illumination device, symmetrical light distribution along the long axis of the first illumination device is achieved. As shown in Figure 6, the optical design enables the long axis light rays of the first illumination device to exhibit symmetrical light distribution.

[0077] The first lighting device provides uniform illumination to the visitor area and allows for wide-angle illumination, thus achieving efficient utilization of the lighting device.

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

[0079] Understandably, given the target installation coordinates and optical axis deflection information, 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 candidate model set of lighting devices that meet the target lighting range can be obtained, and the candidate model set can be further filtered according to the illuminance and intensity requirements of the lighting to determine the target model that meets the lighting coverage requirements.

[0080] Figure 7 shows a schematic diagram of a lighting coverage method for a display scene.

[0081] Referring to Figure 7, to facilitate a comprehensive understanding of the above feasible scenarios, a specific implementation scenario is provided below for illustration.

[0082] In this specific implementation scenario, the overall setting is a supermarket with a ceiling height of 2.8 meters. The viewing area is an aisle with a width of 2.06 meters, and the display area is shelves with a height of 2 meters. The lighting fixtures are LED track lights, installed with a spacing of 3 meters between the track lights.

[0083] Based on the above parameters, the height of the first installation coordinate is determined to be 2.8 meters, positioned in the middle of the aisle, equidistant from the two shelves. The optical axis deflection is 26°. In conjunction with the optical design related to the track light source, the center of gravity of the light spot is shifted, ensuring that the luminous flux is focused on the shelf area. This results in asymmetrical light distribution of the reflected light from the light source, achieving precise projection of light onto the effective area of ​​the shelf facade with uniform illuminance. As shown in Figure 8, referring to the light intensity distribution diagram, the half-intensity beam angle in the short axis direction is 28°, which is sufficient to cover half of the aisle and the top area of ​​the shelves. The long axis direction is parallel to the aisle direction, employing symmetrical light distribution, with a half-intensity beam angle of 105°, achieving continuous light spot coverage along the aisle direction, especially ensuring no dark areas are covered on the top of the shelf surface.
