Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a plant lighting system. Background Technology

[0002] Currently, most high-density planting uses artificial light plant lights for illumination in controlled environments such as containers, plant factories, and tiered greenhouses, managing plant light within these environments. To improve space utilization within containers and ensure the lights don't interfere with daily maintenance and use of the aisles, current container planting systems typically have plant racks on both sides and an aisle in the middle. The aisle has a fixed width; a standard container's internal width is approximately 2280mm, but in practice, at least 750mm needs to be reserved for the aisle. Therefore, theoretically, the maximum utilization rate of planting space is only 67%, and the aisle space is not fully utilized when not harvesting or transplanting. Furthermore, because the existing lights are positioned directly above the plants, the light utilization rate in the peripheral areas is limited. Utility Model Content

[0003] The main purpose of this invention is to propose a plant lighting system that aims to improve the space utilization rate and light utilization rate of controlled environments.

[0004] To achieve the above objectives, the plant lighting system proposed in this utility model includes:

[0005] The fastener has a lifting section for hoisting;

[0006] At least two suspension ropes are arranged parallel to each other at intervals at the fixing member;

[0007] Multiple locking components are spaced apart along the length of each suspension rope;

[0008] Multiple lamp bodies are mounted on locking assemblies of two adjacent suspension ropes, and multiple such assemblies are present along the length of the suspension ropes; and

[0009] A retractable lifting device is provided on the fixing member. The retractable device has an unfolded state and a retracted state. In the unfolded state, multiple lamp bodies are suspended vertically along the suspension rope under the action of gravity and maintain a preset distance. In the retracted state, all lamp bodies are stacked and close together under the rotating shaft.

[0010] In one embodiment, the plant lighting system further includes a rotating shaft rotatably mounted on the fixing member;

[0011] The number of the winding and lifting devices corresponds to the number of the hoisting ropes, and each winding and lifting device includes:

[0012] A winding disc that rotates synchronously with the rotating shaft;

[0013] A rope wound on the winding reel, the free end of which is connected to a locking assembly at the bottom of the corresponding suspension rope or to a lamp body connected to the locking assembly; in the unfolded state, the rope is released.

[0014] In one embodiment, the plant lighting system further includes a drive motor, which is connected to the rotating shaft to provide rotational power.

[0015] In one embodiment, the drive motor is disposed at the end of the rotating shaft.

[0016] In one embodiment, the plant lighting system further includes a speed reducer connected between the drive motor and the rotating shaft; the drive motor is a single motor whose output torque is amplified by the speed reducer to drive the rotating shaft to rotate synchronously.

[0017] In one embodiment, the plant lighting system further includes a protective tube that seals over the drive motor and shaft, wherein the drive motor, reducer, and drive end of the shaft are sealed and housed within the protective tube.

[0018] In one embodiment, the locking assembly is adjustablely fixed at any position on the suspension rope; or the spacing of the locking assembly along the length of the suspension rope is a fixed spacing.

[0019] In one embodiment, the locking assembly includes a bracket and an adjustable tension head; the tension head is sleeved on the suspension rope and can move or be limited relative to the suspension rope, and abuts against the bracket for limitation; the bracket is detachably connected to the lamp body.

[0020] In one embodiment, the lamp body includes a lamp housing, a light-emitting element, and connecting joints located at both ends of the lamp housing; the bracket is detachably connected to the connecting joints.

[0021] In one embodiment, the hanging bracket has a U-shaped structure, comprising a top plate section, a vertical plate section, and a horizontal plate section, with a tension head installed on each of the symmetrical horizontal plate sections; and the suspension rope is configured as a steel wire rope, which passes through the tension heads on the horizontal plate sections.

[0022] In one embodiment, the top plate segment, the vertical plate segment, and the horizontal plate segment enclose a cable cavity, and the vertical plate segment has a wire-passing port; the lamp body cable is introduced into the cable cavity through the wire-passing port and electrically connected to the light-emitting element.

[0023] In one embodiment, the top plate section is provided with guide holes, and all guide holes are aligned to form a guide channel; the coiled rope passes through the guide channel, and the end of the coiled rope is provided with a limiting part, which abuts against the edge of the guide hole of the bottommost bracket.

[0024] In one embodiment, the plant lighting system is used for plant lighting management in a controlled environment, which is configured as a container or a multi-span greenhouse.

[0025] The technical solution of this utility model utilizes a lighting system with both extended and retracted states to dynamically utilize personnel access channels. During non-harvesting, planting, and maintenance phases, the lighting fixtures are fully extended to reduce the access channel size. During harvesting, planting, and maintenance phases, the lighting fixtures are retracted to increase the access channel size, facilitating personnel entry and exit. This meets green principles and has green benefits. Applying this lighting system in controlled spaces can improve space resource utilization (space saving), reduce carbon emissions (electricity saving / increased utilization rate), and lower maintenance difficulty, thereby increasing benefits and meeting the core requirements of green agricultural development.

[0026] The lighting system's vertical retraction / expansion allows for dynamic adjustment of the operating aisle width. When the lights are extended and operating in illumination mode (non-maintenance period), they are lowered vertically, occupying a portion of the original aisle's vertical space. During maintenance (retracted state), the lights fold upwards, freeing up vertical and horizontal space in the lower aisle, restoring or expanding the operating aisle for easier access for personnel and equipment, and facilitating maintenance and harvesting. This achieves "on-demand allocation" of the operating aisle space. During the peak light-growth period (which accounts for most of the time), the aisle is minimized, maximizing the use of valuable horizontal planting area. Wider aisles are only occupied during brief periods of operation, significantly improving overall space utilization. Compared to traditional solutions with central lighting and crops on either side, this solution reduces the width of the operating aisle, allowing the saved horizontal space to be used to increase the width of planting racks or add new planting layers, maximizing the use of valuable horizontal planting area. Furthermore, by arranging the lights centrally and vertically, the light path is optimized, waste is reduced, and edge lighting is improved, avoiding the problem of excessive light loss and waste when the lights were installed above the planting rack in the past, where the light from the edge lights was scattered outwards (towards the aisle).

[0047] Currently, most high-density planting uses artificial light plant lighting to manage plant light in controlled environments such as containers, plant factories, and tiered greenhouses. This is done to improve space utilization within containers and ensure that the lighting fixtures do not interfere with daily maintenance and use in aisles.

[0048] Taking container planting as an example, the layout of existing container planting systems generally involves placing plant cultivation racks on both sides and an aisle in the middle. The aisle has a fixed width; the internal width of a standard container is approximately 2280mm, and in practice, at least 750mm needs to be reserved for the aisle. Therefore, theoretically, the maximum utilization rate of planting space is only 67%, and the aisle space is not fully utilized when not harvesting or transplanting. Moreover, because the existing solutions have large lighting fixtures directly above the plants, the utilization rate of light from the lighting fixtures in the edge areas is limited.

[0049] This invention proposes a plant lighting system to improve the space utilization and light utilization rate of a controlled environment.

[0050] Please see Figure 1 In one embodiment of this utility model, the plant lighting system includes:

[0051] The fastener 10 has a lifting section for hoisting;

[0052] At least two suspension ropes 20 are arranged parallel and spaced apart at the fixing member 10;

[0053] Multiple locking components 30 are spaced apart along the length of each suspension rope 20;

[0054] Multiple lamp bodies 40 are mounted on locking assemblies 30 of two adjacent suspension ropes 20, and multiple ropes are provided along the length of the suspension ropes 20; and

[0055] The winding and lifting device 50 is located on the fixing member 10.

[0056] Reference Figure 1 and Figure 2 The winding device has an unfolded state; refer to Figures 2 to 5 The winding device has a retracted state, wherein: in the unfolded state, multiple lamp bodies 40 are suspended vertically along the suspension rope 20 under the action of gravity and maintain a preset row spacing; in the retracted state, all lamp bodies 40 are stacked and close together below the rotating shaft 60.

[0057] Reference Figure 1 and Figure 3 In one embodiment, multiple fasteners 10 are provided, and the multiple fasteners 10 are hoisted onto, for example, the top of a container or other components via a hoisting unit; each fastener 10 is also provided with a hoisting rope 20, such as three hoisting ropes 20 for light groups arranged in three columns along the length of the container (each light group has multiple rows of light bodies 40).

[0058] In other embodiments, the fastener 10 has an extended length, and multiple lifting parts are provided in the extended length direction.

[0059] The winding and lifting device 50 can be manual or electric, and there can be one or more of them. In one case, it is arranged in the middle of the lamp body 40.

[0060] Reference Figures 1 to 5 In this embodiment, the lighting system also includes a rotating shaft 60, which is rotatably mounted on the fixing member 10.

[0061] Specifically, the number of the winding and lifting devices 50 corresponds to the number of the lifting ropes 20, and each of the winding and lifting devices 50 includes:

[0062] A winding disc 51 that rotates synchronously with the rotating shaft 60;

[0063] The free end of the rope 52 wound on the winding disc 51 is connected to the locking assembly 30 at the bottom of the corresponding suspension rope 20 or to the lamp body 40 connected to the locking assembly 30.

[0064] In the unfolded state, the winding rope 52 is released, and the multiple lamp bodies 40 are suspended vertically along the suspension rope 20 under the action of gravity and maintain a preset row spacing; in the retracted state, the rotating shaft 60 drives the winding disc 51 to wind the winding rope 52, pulling the locking component 30 at the bottom of each suspension rope 20 to rise, so that all the lamp bodies 40 are stacked and close together under the fixing member 10 in sequence.

[0065] This invention's technical solution dynamically adjusts the width of the operating passageway by retracting / unfolding the lighting system along the vertical direction. When the lighting system is in the unfolded state and operating in illumination mode (non-maintenance period), the lights are lowered vertically, occupying a portion of the original vertical space of the passageway. During maintenance (retracted state), the lights are stacked upwards, releasing the vertical and horizontal space of the passageway below, restoring or expanding the operating passageway, facilitating access for personnel and equipment for maintenance and harvesting. This achieves "on-demand allocation" of the operating passageway space. During the period when crops are primarily growing under light (occupying most of the time), the passageway is minimized, maximizing the use of valuable horizontal planting area. A wider passageway is only occupied during the brief periods when operation is needed, significantly improving overall space utilization. Compared to the traditional scheme of central lighting with crops on both sides, this solution reduces the width of the operating passageway, allowing the saved horizontal space to be used to increase the width of the planting rack or add new planting layers, maximizing the use of valuable horizontal planting area. Furthermore, by arranging the lights centrally and vertically, the light path is optimized, waste is reduced, and edge lighting is improved, avoiding the problem of excessive light loss and waste when the lights were installed above the planting rack in the past, where the light from the edge lights was scattered outwards (towards the aisle).

[0066] Specifically, the fastener 10 (fixed bracket) serves as the basic load-bearing and hoisting structure of the system. The fastener 10 has a hoisting part for fixing and suspending the entire lighting system on the top of the container to solve the problem of space utilization and maximize the use of the top. The fastener 10 also has a mounting position for a rotatable shaft 60.

[0067] The rotating shaft 60 provides rotational power to drive the winding lifting device 50. The rotating shaft 60 is connected to a motor or manual drive mechanism.

[0068] The winding reel 51 (drum or pulley, etc.) rotates synchronously with the shaft 60, and the winding rope 52 (belt, etc.) is wound around the winding reel 51. The end of the winding rope 52 is fixedly connected to the mounting part at the bottom of the suspension rope 20 (usually the bottom lamp body 40 of each column or its connection point).

[0069] The suspension rope 20 supports the weight of the lamp body 40 and provides a vertical track for the lamp body 40 to be raised and lowered. There are at least two suspension ropes 20, which are arranged in parallel at intervals along the length of the rotating shaft 60 (which determines the number of "columns" of the lamp).

[0070] In one embodiment, a plurality of locking components 30 are spaced apart along the length of each suspension rope 20 and are operablely adjustable to a fixed position on the suspension rope 20. The locking components 30 have a locking structure to maintain the position, so as to adjust the spacing of different lamp bodies 40 according to the usage scenario and meet different usage requirements.

[0071] The rotating shaft 60 releases the winding rope 52 (loosening) via a motor or manually, and the lamp body 40 falls vertically along the suspension rope 20 under the action of gravity. The mounting parts on the suspension rope 20 are spaced at a fixed interval, so that the lamp bodies 40 are arranged in parallel and at intervals, forming multiple rows of vertical "light curtains".

[0072] The lamp body 40 is fully extended above the operating aisle, illuminating the crops on both sides downwards. Compared to the traditional solution where the lamp group is placed in the middle of the container aisle to illuminate the crops on both sides, this solution can add a row of crops to the original aisle, forming two aisles. The lamp body 40 is suspended in the middle of the aisle to solve the problem of edge lighting effect. The width of the aisle can be minimized (only a narrow gap needs to be left), and the width of the planting area is maximized to improve space utilization.

[0073] The light assembly (light source) includes multiple independent light bodies 40 (LED light strip / light panel modules), each light body 40 is horizontally installed between the mounting parts of two adjacent lifting ropes 20 in the same row or between the locking components 30, perpendicular to the length direction of the lifting ropes 20 (i.e. along the width direction of the container).

[0074] Reference Figure 1 and Figure 2 When the light fixtures are in the deployed state, their lighting mode addresses the issues of low space utilization inside the container and wasted planting area in fixed aisles. Specifically, by dynamically adjusting the width of the operating aisle, during non-maintenance periods (deployed state): the lights are lowered vertically, occupying a portion of the original vertical space of the aisle. At this time, the width of the operating aisle can be reduced, and the saved horizontal space can be used to increase the width of the planting racks or add new planting layers.

[0075] Refer to 3 to Figure 5 During maintenance (storage state): the lights are stacked upwards, freeing up vertical and horizontal space in the lower passageway, restoring or expanding the operating passageway, facilitating access for personnel and equipment for maintenance and harvesting. This achieves "on-demand allocation" of the operating passageway space. During the peak light-growth period (which accounts for most of the time), the passageway is minimized, maximizing the use of valuable horizontal planting area. A wider passageway is only occupied during brief periods when operation is needed, significantly improving overall space utilization.

[0076] Furthermore, when the light fixtures are in their extended state, they also solve the problems of uneven light utilization and poor edge lighting efficiency caused by traditional lighting layouts. Specifically, the light fixtures are centrally suspended, with the light efficiently covering the plant canopy vertically downwards. In the extended state, the light fixtures hang like a "light curtain" in the operating aisle, emitting light that primarily shines vertically downwards onto the plants on the planting racks on both sides. Because the light fixtures themselves are in the aisle, their light directly illuminates the canopy of the plants on both sides with almost no obstruction, including the edge plants near the aisle. This avoids the problem of significant light loss and waste caused by edge lights scattering outwards (towards the aisle) when the lights are mounted above the planting racks in the past. This more rational light path design effectively concentrates the light that would otherwise be wasted above the aisle onto the crop canopy area on both sides, especially significantly improving the light intensity and uniformity in the edge areas, increasing overall light utilization efficiency, and reducing light waste.

[0077] When the light assembly is in its retracted state (maintenance operation mode), the rotating shaft 60, via a motor or manual winding of the rope 52, pulls the locking component 30 at the bottom of the suspension rope 20 upwards. The bottom light body 40 is lifted first, and subsequent light bodies 40, due to the spacing limitations of the installation parts, are stacked upwards sequentially under the action of gravity and traction. Finally, all light bodies 40 are stacked and stored tightly against the bottom of the fixing component 10 on the top of the container (similar to a folding curtain), completely freeing up the vertical and horizontal space below, maximizing the operating passage and facilitating unobstructed maintenance. This solves the problem of traditional fixed light fixture structures affecting maintenance flexibility. Specifically, the quickly retractable vertical "light curtain" allows the lights to quickly fold upwards to the top like a "curtain" when operations requiring personnel to approach the plant, such as harvesting, transplanting, or equipment maintenance, are needed. Operators do not need to worry about bumping into the light fixture structure and can freely perform various operations, including tasks requiring reaching to the top or back of the plant. Once the operation is complete, the lights resume illumination, greatly improving the convenience, safety, and efficiency of maintenance. There's no longer a need for manual labor to move the bulky, fixed light fixtures, enabling a rapid switch between lighting and workspace.

[0078] In summary, this lighting system, through vertical retraction / expansion, minimizes aisle space during the peak light-growth period (which accounts for the majority of the time), maximizing the use of valuable horizontal planting area. It only occupies wider aisles during brief periods when operation is required, significantly improving overall space utilization and achieving maximum space efficiency.

[0079] Furthermore, by centrally hanging and vertically illuminating the light source, the light path is optimized, waste is reduced, and edge lighting is improved. This avoids the problem of excessive light loss and waste when edge lights are mounted above the planting racks, resulting in significant light scattering outwards (towards the aisle). This more rational light path design effectively concentrates light that was previously wasted above the aisle onto the crop canopy areas on both sides, significantly improving the light intensity and uniformity in the edge areas, increasing overall light utilization efficiency, and reducing light waste. By switching between extended and retracted states, obstacles above the plants are removed, creating an ideal operating environment. This solves the problem of traditional fixed lighting fixtures affecting maintenance flexibility, eliminating the need for laborious manual removal of bulky fixed light stands. It enables rapid switching between lighting and workspace, and seamless, quick switching between two spatial modes (planting / maintenance) to adapt to different needs.

[0080] To avoid the labor-intensive and inefficient nature of manual operation and to achieve automated operation, the lighting system also includes a drive motor 53, which is connected to the rotating shaft 60 to provide rotational power.

[0081] Specifically, for ease of maintenance and to avoid the need for complete disassembly, the drive motor 53 is located at the end of the rotating shaft 60. Of course, the drive motor 53 can also be located in the middle or at both the middle and the end, such as in the middle and at both ends.

[0082] Furthermore, due to the poor synchronization and high cost of multi-motor systems, a single motor drives the entire system, and torque control ensures that all winding discs 51 are raised and lowered synchronously. Specifically, the lighting system also includes a reducer (not shown in the figure), which is connected between the drive motor 53 and the rotating shaft 60. There is one drive motor 53, and its output torque is amplified by the reducer to drive the rotating shaft 60 to rotate synchronously.

[0083] Combination Figure 2 Furthermore, to prevent motor / bearing corrosion and adapt to the high humidity environment of agriculture, a fully enclosed moisture-proof structure is designed. The lighting system also includes a protective tube 70, which seals over the drive motor 53 and shaft 60. The drive ends of the drive motor 53, reducer, and shaft 60 are sealed and housed within the protective tube 70. For easy disassembly, the protective tube 70 includes a removable end cap with a sealing ring between the end cap and the protective tube 70. The end cap can also be configured as a winding disc 51, allowing for motor / reducer maintenance by removing the end cap. To improve moisture protection, the inner wall of the protective tube 70 is coated with a moisture-absorbing layer to enhance moisture resistance and address condensation issues. Understandably, the lighting system also includes a height sensor and a controller. The height sensor detects the position of the lamp body 40 and feeds it back to the controller. The controller dynamically adjusts the speed of the drive motor 53 to achieve a smooth start and stop, preventing damage to the stacked lamp bodies 40 due to rapid lifting and lowering collisions. Of course, a smooth start and stop can also be achieved solely through the drive motor 53 and reducer to prevent damage to the stacked lamp bodies 40 due to rapid lifting and lowering collisions.

[0084] In one embodiment, the fastener 10 and the protective tube 70 are integrated, such as the fastener 10 (fixed bracket) being welded to the protective tube 70; or the fastener 10 and the protective tube 70 being integrally formed.

[0085] In this embodiment, the winding disc 51 is mounted on the fixing member 10. Since there are multiple winding discs 51, the lifting parts of multiple fixing members 10 can lift the lighting system at multiple points, and the protective cover and the fixing member 10 can be better sealed.

[0086] Combination Figure 4 and Figure 5 Furthermore, in order to facilitate the disassembly and maintenance of the lamp body 40, the locking assembly 30 includes a bracket 31 and an adjustable tension head 32; the tension head 32 is sleeved on the suspension rope 20 and can move or be limited relative to the suspension rope 20, and abuts against the bracket 31 for limitation; the bracket 31 is detachably connected to the lamp body 40.

[0087] Specifically, the lamp body 40 includes a lamp housing 41, a light-emitting element (not shown in the figure), and connecting connectors 42 located at both ends of the lamp housing 41; the bracket 31 is detachably connected to the connecting connectors 42, and can be adapted to various lamp housings 41 by connecting the bracket 31 through the connecting connectors 42.

[0088] In one embodiment, the bracket 31 and the connector 42 are connected by a male and female plug mating method.

[0089] In one embodiment, to improve connection reliability, the bracket 31 and the connecting joint 42 are fastened with threads, which has good vibration resistance and avoids loosening. Specifically, the bracket 31 has a fixing part (not shown in the figure), and the connecting joint 42 has a connecting part (not shown in the figure). The fixing part and the connecting part are fastened together by fasteners.

[0090] Combination Figure 5 Furthermore, single-point suspension has poor stability. To improve the stability of the lighting system, symmetrical force is used to enhance stability. The steel wire rope is designed for tensile strength. The bracket 31 has a U-shaped structure, including a top plate section 311, a vertical plate section 312, and a horizontal plate section 3313. Each of the symmetrical horizontal plate sections 3313 has a tension head 32 installed on it. The suspension rope 20 is a steel wire rope, and it passes through the tension heads 32 on the horizontal plate sections 3313. Alternatively, the suspension rope 20 can pass through the middle of the bracket 31, and the coiled rope 52 is arranged parallel to the suspension rope 20.

[0091] Combination Figure 4 and Figure 5Furthermore, to avoid interference with the lifting rope and to improve aesthetics, concealed wiring is adopted. The top plate section 311, the vertical plate section 312, and the horizontal plate section 3313 enclose a cable cavity 31a, and the vertical plate section 312 has a wire passage 31b. The lamp body 40 cable is introduced into the cable cavity 31a through the wire passage 31b and electrically connected to the light-emitting element.

[0092] Furthermore, in order to ensure the accuracy of the lifting trajectory, the top plate section 311 is provided with guide holes 31c, and all guide holes 31c are aligned to form a guide channel; the winding rope 52 passes through the guide channel, and its end is provided with a limiting part, which abuts against the edge of the guide hole 31c of the bottommost hanging bracket 31.

[0093] Furthermore, the lighting system is used for plant light management in a controlled environment. Controlled environment light management means the lighting system is used to provide light to plants. The controlled environment includes fully enclosed scenarios such as greenhouses / containers, and the lighting system has intelligent photoperiod control attributes.

[0094] Specifically, the controlled environment refers to shipping containers or multi-span greenhouses. In vertical agriculture, the lighting system is most effective when placed inside containers or greenhouses for planting (plant cultivation requires uniformity in light and environmental control (the difficulty of controlling different sizes varies)). Therefore, containers / greenhouses (with limited space) have a greater advantage. The lighting system can save aisle space, improve space utilization, increase planting area, thereby increasing planting yield and reducing environmental control pressure.

[0095] In summary, this utility model utilizes a lighting system with both extended and retracted states to dynamically utilize the personnel operation channel. During non-harvesting, planting, and maintenance phases, the lighting system is fully extended to reduce the operation channel size. During harvesting, planting, and maintenance phases, the lighting system needs to be retracted to increase the operation channel size and facilitate personnel access.

[0096] This foldable lighting system also meets green principles and has green benefits (the core of green principles is efficient resource utilization and environmental friendliness). Applying this system in controlled spaces can improve space resource utilization (saving space), reduce energy consumption (saving electricity / increasing utilization rate), and reduce maintenance difficulty, thereby increasing benefits and meeting the core requirements of green agricultural development. On one hand, the lights can be folded up like "curtains" to free up operating space (solving the problem of passageway space occupation). By dynamically folding and releasing passageways through the lighting system, space utilization can be improved, providing planting area. The original scheme of central plant lights and planting units on both sides can be transformed into a three-row planting unit arrangement with plants on both sides and in the middle. The lighting system dynamically utilizes the personnel operating passageway by folding and releasing passageways. During non-operating periods, the 40-layer light body can be stacked and stored at the top, minimizing the width of the operating passageway (e.g., compressing it from a fixed 750mm to 450mm), thus increasing the utilization rate of container planting space. Adding one planting unit is equivalent to increasing crop output by half with the same energy consumption. On the other hand, hanging the lights vertically provides more even lighting (solving the problem of wasted light at the edges). During non-harvesting, planting, and maintenance phases, the lights can be fully extended to form a curtain-like vertical light screen. The light bodies 40 are arranged in rows and columns along the hanging ropes 20, and when extended, the horizontal spacing matches the spacing between the plant rows (adjusted via the locking component 30), ensuring that the light source covers the planting area. Precise light management of the planting units is achieved through the precise positioning of the light bodies 40, improving the light / electricity conversion efficiency. This solves the problem of traditional lights being fixed directly above the plants, with light from the edge light bodies 40 scattering into the aisle, resulting in ineffective light energy loss.
