Description

Technical Field

[0001] This invention relates to the field of agricultural lighting devices, and in particular to a fence-type plant supplement light with adjustable light angle and height and circuit redundancy design, suitable for three-dimensional plant supplement light in greenhouses, vertical farms and other scenarios. Background Technology

[0002] Plant grow lights promote photosynthesis in plants by simulating the solar spectrum, which is especially crucial in low-light environments. Traditional grow lights are mostly top-mounted or side-fixed, which have problems such as many blind spots, poor adjustment flexibility, and low circuit reliability. For vertical planting systems (such as multi-layer cultivation racks), it is necessary to achieve 360° uniform lighting without blind spots, and the light parameters need to be dynamically adjusted according to the plant's growth stage.

[0003] Chinese patent CN109340668A proposes a height-adjustable LED plant light, but it only supports overall height adjustment and cannot adjust the local lighting angle for individual plants. Utility model patent CN212786995U designs a multi-strip combined supplementary lighting device, but the strips use a series circuit, so a single strip failure will cause the entire device to go out. While common fence-type supplementary lights on the market can surround plants, they have problems such as fixed illumination range, non-adjustable strip angles, and the need to disconnect power during maintenance.

[0004] The existing technology has the following drawbacks: 1. Insufficient illumination flexibility: The fixed beam angle leads to uneven light exposure for plants, and small plants are easily blocked; 2. Limited structural adjustment: Height adjustment requires overall disassembly, and the lamp bar angle cannot be independently rotated to adapt to different canopy layers; 3. Low circuit reliability: A single point failure in the series circuit can cause system paralysis, resulting in high maintenance costs. Summary of the Invention

[0005] To address the problems of fixed illumination angle, low circuit reliability, and inconvenient height adjustment in existing plant grow lights, this invention provides a fence-type plant grow light, aiming to achieve: 1. Independent angle adjustment for each light strip, adapting to different canopy plants; 2. Modular parallel circuit, supporting hot-swappable replacement of faulty light strips; 3. Rapid and stepped height adjustment to match the needs of plant growth cycles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fence-type plant grow light includes:

[0008] Vertical support system: It consists of a lamp mounting column and a detachable support column. The support column is a telescopic sleeve with positioning holes and can be locked in 5cm increments by spring pins.

[0009] Enclosed lighting system: Multiple LED light source components are horizontally connected to adjacent light fixture mounting columns via rotary joints to enclose and form a planting space;

[0010] Modular light source unit: Each LED light source component includes a PC diffuser cover, multi-segment spliced ​​LED light strips, and an independent driver power supply box;

[0011] Redundant circuit architecture: Each LED strip is connected in parallel to the main control module inside the lamp mounting column through waterproof connectors. When a single LED strip is removed, the remaining LED strips automatically continue to work.

[0012] The core innovations of this invention include:

[0013] 1. Dynamic angle adjustment mechanism: The rotary joint has a built-in damping shaft, which allows the LED light source assembly to rotate ±30° around the horizontal axis. Each light strip can be independently adjusted for pitch angle to eliminate plant shading.

[0014] 2. Fault isolation circuit design: The driver power supply box provides independent power to each LED strip. After any LED strip is removed through the plug-in terminal, the parallel circuit automatically shields that branch, ensuring zero downtime for system maintenance.

[0015] 3. Composite Adjustable Structure: The telescopic structure of the support column and the rotating structure of the light source assembly work together to achieve a three-dimensional adjustable illumination range: Vertical: The height of the support column can be adjusted from 50 to 150 cm; Horizontal: The single light strip has a 120° wide-angle beam superimposed and enclosed layout to cover the planting area with omnidirectional supplemental lighting.

[0016] Specifically, the present invention provides a fence-type plant supplement light comprising: a vertically arranged lamp mounting column and an adjustable height support column, wherein the support column is located below the lamp mounting column; multiple horizontally extending LED light source components connected between adjacent lamp mounting columns and forming a planting space; the lamp mounting column has a hollow cavity for accommodating electrical components; the LED light source components include a light-transmitting cover, at least one LED light strip, and a driver power supply box.

[0017] Preferably, the lamp mounting column and the support column are detachably connected by a snap-fit ​​connector, and a sealing ring is provided between the lamp mounting column and the support column for dust and water protection.

[0018] Preferably, the support column is a telescopic sleeve structure with positioning holes on its surface for stepped height adjustment.

[0019] Preferably, the LED light source assembly is connected to the lamp mounting column via a rotary joint, allowing the LED light source assembly to rotate up and down around a horizontal axis to adjust the angle.

[0020] Preferably, the LED light strip is composed of multiple independent light strips spliced ​​together, and the beam angle of a single light strip is ≥120°.

[0021] Preferably, each light strip has waterproof plug terminals at both ends to enable quick electrical connection between the light strips.

[0022] Preferably, the drive power supply box is equipped with an independent drive circuit, and the drive circuits of each LED light strip are connected in parallel to the main control module in the lamp mounting column.

[0023] Preferably, the positioning hole, in conjunction with a spring pin, locks the height of the support column, with an adjustment step of 5cm.

[0024] Preferably, the light-transmitting cover is a PC material diffuser cover that covers the outside of the LED light strip.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. Improved uniformity of illumination: The combination of wide-angle light strips (beam angle ≥120°) and PC diffuser achieves an illumination uniformity of over 85% within the enclosed area, a 40% improvement over traditional solutions;

[0027] 2. Improved maintenance efficiency: Replacement time for faulty light strips is ≤2 minutes (traditional series solutions require complete power outage and disassembly).

[0028] 3. Enhanced adaptability: The dual adjustment mechanism of height and angle can match the needs of crops with different plant heights, such as tomatoes and strawberries, at various growth stages. Attached Figure Description

This is only for the convenience of description and is not intended to indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention.

[0036] The terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly indicating the importance of the technical features shown.

[0037] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] The fence-type plant supplement light of this invention is mainly used for three-dimensional plant supplementation in greenhouses, vertical farms, and other similar settings. The following figures and the core structure of the technical solution are used to describe in detail its components, working principle, usage method, and typical application scenarios.

[0039] Please see Figures 1-5 The fence-type plant supplement light of this invention consists of three parts: a vertical support system, an enclosed supplement light system, and a redundant circuit system.

[0040] The vertical support system comprises a lamp mounting column 1 and a support column 2. Lamp mounting column 1 is made of 40mm×40mm aluminum alloy square tubing, with an internal hollow cavity to accommodate the main control module. Support column 2 is a three-stage stainless steel telescopic sleeve, with stepped height adjustment achieved through positioning holes 201 spaced 5cm apart on the sidewalls and a spring pin 7. The 7.9mm pin head of spring pin 7 forms an interference fit with the positioning hole 201, ensuring a secure, wobbly lock within a height range of 50-150cm. Lamp mounting column 1 and support column 2 are detachably connected via a snap-fit ​​connector 4, which has a silicone sealing ring on its inner side for dust and water resistance.

[0041] The core of the encircling lighting system consists of multiple LED light source components 3, which are horizontally connected to adjacent lamp mounting posts 1 via rotary joints 5. The rotary joints 5 incorporate nylon gear damping shafts and conductive slip rings, allowing the light source components 3 to rotate within a ±30° range around a horizontal axis. Each component includes: a PC material curved light-transmitting cover 301 (92% light transmittance), six 50cm long spliced ​​LED light strips 302 (120° beam angle per strip), and an independent driver power supply box 303.

[0042] The key to the redundant circuit system lies in the parallel architecture: the main control module branches out into 6 circuits with fuses, which are connected to each driver power supply box 303 via conductive slip rings. Each light strip 302 has IP67-rated three-pin waterproof connectors 6 at both ends. When a single light strip fails and is removed, the fuse of the corresponding branch blows, and the remaining light strips automatically continue to work (voltage fluctuation < 0.5V).

[0043] The working principle of this invention embodiment is as follows:

[0044] 1. Light adjustment: The damping shaft of the rotary joint 5 provides torque resistance, allowing the LED light strip 302 to be manually fixed at any tilt angle, and to cover different canopy layers of the plant with a 120° wide-angle beam;

[0045] 2. Circuit redundancy: The parallel architecture forms an independent power supply branch. A single light strip failure will only trigger the fuse of this branch to blow, avoiding system-wide power outages.

[0046] 3. Height Adaptability: Spring pin 7 can be inserted into positioning holes 201 at different heights to quickly match the needs of plant growth cycles.

[0047] The operating procedure for this device is as follows (taking tomato cultivation as an example):

[0048] 1. Assembly: Stretch the support column 2 to the target height (e.g., 50cm for seedlings) and insert the spring pin 7 to lock it; the lamp mounting column 1 is snapped onto the top of the support column 2, with a spacing of 1.5m between adjacent columns; insert the rotating joints 5 into both ends of the LED light source assembly 3 and press the plug-in terminal 6 to connect the circuit.

[0049] 2. Adjustment: Rotate the upper light bar to +20° to illuminate the canopy of tall plants, and adjust the lower light bar to -10° to cover the basal leaves; during the plant's growing season, raise the support column by 10cm every two weeks (adjust by pulling out the spring pin 7 step by step).

[0050] 3. Maintenance: The fault light strip can be replaced by simply unplugging and plugging in terminal 6 without powering off (the system continues to run).

[0051] Application scenarios of this invention include:

[0052] 1. Greenhouse fruit and vegetable cultivation (such as tomatoes and cucumbers)

[0053] Scenario requirement: Increased sunlight exposure to the lower part of the fruit is needed during the fruit enlargement period;

[0054] Advantages of this solution: The lower light bar is adjusted to -15°, allowing the light beam to penetrate the canopy and improve the fruit set rate at the bottom.

[0055] 2. Multi-level vertical farm

[0056] Scenario requirement: 0.5m narrow-pitch planting racks require lateral supplemental lighting;

[0057] Advantages of this solution: shortening the light strip to 30cm, 150° beam angle combined with rotation adjustment, achieving 80% uniformity of illumination in narrow spaces.

[0058] 3. Seedling factory

[0059] Scenario requirement: Frequent adjustments to light intensity to match seedling growth;

[0060] Advantages of this solution: Spring pin 7 enables 5cm step adjustment, completing the entire column height adjustment in 10 seconds.

[0061] The embodiments of the present invention can achieve the following technical effects:

[0062] Illuminance uniformity: Tested at 9 points within a 1m² enclosed area, the uniformity reached 85.2% (compared to ≤60% for traditional methods).

[0063] Repair efficiency: The average time to replace a single light strip is 1 minute and 45 seconds (the traditional solution requires complete power disconnection and disassembly, which takes ≥15 minutes).

[0064] Adjustment accuracy: After 10 repetitions to lock the height at 100cm, the deviation is ≤±1mm.
