Abstract
Description
Technical Field
[0001] This application relates to the field of lighting device technology, and in particular to a supplementary lighting module. Background Technology
[0002] Sunlight is closely related to crop growth. Maximizing the capture of light energy and fully utilizing the potential of plant photosynthesis directly affects the efficiency of agricultural production. In recent years, driven by market demand, greenhouses have been widely used to produce off-season flowers, fruits, and vegetables. However, due to the short daylight hours in winter and spring, crop growth is slow and yields are low. Therefore, supplemental lighting is needed to improve crop growth.
[0003] Traditional grow lights are categorized into overhead grow lights and inter-plant grow lights based on their placement on the plants. Overhead grow lights primarily provide vertical illumination and are suitable for shorter plants such as melons, fruits, and flowers. Inter-plant grow lights primarily provide horizontal illumination and are suitable for taller plants such as tomatoes and cucumbers. When the type of plant changes or the plant's height changes, the direction of illumination needs to be adjusted. However, once installed, the direction of illumination with existing grow lights is fixed and cannot be changed. The only solution is to remove and reinstall the existing overhead or inter-plant grow lights, which is time-consuming and labor-intensive. Utility Model Content

[0024] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0025] This application discloses a supplementary lighting module.
[0026] Reference Figure 1 and Figure 3 A supplementary lighting module includes a lamp housing 1, a top supplementary light source 4, and a side supplementary light source 5. The top supplementary light source 4 includes a lamp panel 41, a first lamp tube 42, and several lamp beads 43. The lamp panel 41 is installed inside the lamp housing 1, and the several lamp beads 43 are evenly installed on the side of the lamp panel 41 away from the inside of the lamp housing 1. The first lamp tube 42 is installed inside the lamp housing 1 and emits light in the same direction as the lamp beads 43. The side supplementary light source 5 includes a lamp holder 51 and a second lamp tube 52. The second lamp tube 52 is installed inside the lamp holder 51. The length direction of the lamp holder 51 is parallel to the length direction of the lamp housing 1. The top of the lamp housing 1 is provided with a groove 2 for placing the second lamp tube 52. Both ends of the lamp holder 51 are provided with retractable extension brackets 6.
[0027] The top supplementary light source 4 provides vertical supplementary light, suitable for low-growing plants; the side supplementary light source 5 provides horizontal supplementary light through the lamp holder 51 parallel to the length of the lamp housing 1, suitable for tall plants; the two are integrated into the same module, which can flexibly switch or provide supplementary light in different directions at the same time, solving the problem of traditional supplementary lights needing to be removed and reinstalled, adapting to changes in plant species or growth height adjustments, and the extension brackets 6 at both ends of the lamp holder 51 can be stored, facilitating transportation and storage. The side supplementary light source 5 is limited and installed on both sides of the lamp housing 1 through the bracket structure, simplifying the installation process and requiring no additional tools.
[0028] In this embodiment, the top-fill light source 4 includes two light sources, which are evenly distributed along the width direction of the lamp housing 1. The length direction of the lamp plate 41 is parallel to the length direction of the lamp housing 1, and the first lamp tube 42 is installed between two adjacent lamp plates 41.
[0029] In this embodiment, the side-supplement light source 5 includes two, and the two side-supplement light sources 5 are symmetrically arranged along both sides of the lamp housing 1.
[0030] A reflector 3 is provided on the lamp housing 1, and a first lamp tube 42 is provided inside the reflector 3. The reflector 3 has a reflective surface on the side facing the first lamp tube 42. In this embodiment, three first lamp tubes 42 are provided and are evenly installed inside the reflector 3.
[0031] Multiple top supplementary light sources 4 are evenly distributed along the width of the lamp housing 1, expanding the coverage of top supplementary lighting, avoiding blind spots caused by a single light source, suitable for wide planting areas, improving the uniformity of top lighting, and promoting the balanced growth of low-growing crops.
[0032] The first lamp tube 42 is installed between adjacent lamp panels 41, and its light emission direction is coordinated with that of the lamp bead 43 to form a vertical superimposed illumination, which enhances the top illumination intensity and improves the photosynthetic efficiency.
[0033] The first lamp tube 42 is placed inside the reflector 3. The reflective surface reflects and converges the scattered light to the target area, reducing light energy loss and improving the concentration and effective illumination distance of the top supplementary light. It is suitable for high-ceilinged scenes such as greenhouses, reducing energy consumption and enhancing the supplementary light effect.
[0034] Reference Figure 1 , Figure 2 and Figure 3The extension bracket 6 includes an extension rod 61 and a slider 62. One end of the extension rod 61 is rotatably connected to the lamp holder 51, and the other end of the extension rod 61 is rotatably connected to the slider 62. The lamp housing 1 is provided with a slide rail 9. In this embodiment, the slide rail 9 is set as a dovetail block. The slider 62 is provided with a dovetail groove for accommodating the dovetail block. The slider 62 moves horizontally along the width direction of the lamp housing 1 via the slide rail 9. The extension rod 61 and the lamp holder 51 are rotatably connected via a damping shaft 10. A positioning element 7 is provided between the end of the extension rod 61 away from the lamp holder 51 and the slider 62. The positioning element 7 includes a rotating shaft 71, a ratchet 72, a pawl 73, and a sliding rod 74. One end of the rotating shaft 71 is fixedly connected to the extension rod 61, and the other end of the rotating shaft 71 is rotatably connected to the slider 62. The ratchet 72 is coaxially fixedly connected to the rotating shaft 71. One end of the sliding rod 74 is fixedly connected to the slider 62. The pawl 73 is slidably sleeved on the sliding rod 74. The axes of the sliding rod 74 and the ratchet 72 are parallel. The pawl 73 and the ratchet teeth of the ratchet 72 are engaged. A torsion spring is provided between the pawl 73 and the slider 62. The torsion spring is sleeved on the sliding rod 74. One end of the torsion spring is fixedly connected to the side wall of the pawl 73, and the other end of the torsion spring is fixedly connected to the side wall of the slider 62. A lever 11 is provided on the top of the pawl 73.
[0035] The extension rod 61 is connected to the lamp holder 51 via the damping shaft 10, allowing it to rotate at any angle and remain fixed, thus enabling adjustment of the horizontal supplementary lighting angle. The angle of the extension rod 61 is locked by the engagement of the pawl 73 and the ratchet 72, providing a reliable positioning effect and preventing the light source from shaking during the supplementary lighting process. The handle 11 can be easily unlocked and adjusted quickly, improving the ease of operation.
[0036] When arranging the side-supplement light source 5, firstly, use the lever 11 to pull out the pawl 73 along the axis of the sliding rod 74, releasing the engagement between the pawl 73 and the ratchet 72. Then, move the lamp holder 51 along with the second lamp tube 52 away from the bottom of the groove 2. At this time, the extension rod 61 rotates, pulling the lamp holder 51 along with the extension rod 61 towards the side wall of the lamp housing 1. The slider 62 slides on the slide rail 9, and the lamp holder 51 separates from the lamp housing 1 to one side of the lamp housing 1. After the lamp holder 51 is moved to the desired position, release the lever 11. The pawl 73 moves towards the slider 62 under the drive of the torsion spring. The pawl 73 engages with the ratchet teeth of the ratchet 72, thus limiting the position of the extension rod 61 and the lamp holder 51. Finally, twist the lamp holder 51. The lamp holder 51 and the extension rod 61 are connected by the damping shaft 10, so that the lamp holder 51 rotates to the desired illumination angle.
[0037] Reference Figure 1 and Figure 4 The top of the lamp housing 1 is provided with a heat dissipation cover 12, and the heat dissipation cover 12 is provided with multiple heat dissipation holes 13.
[0038] The heat generated by the supplementary lighting module during operation is quickly dissipated through the heat dissipation hole 13, which prevents the LED beads 43 and the first lamp tube 42 from aging due to high temperature, extends the service life of the supplementary lighting module, and maintains stable light output to achieve a good supplementary lighting effect.
[0039] Reference Figure 4 In this embodiment, in order to fix the supplementary lighting module to an external structure, such as a crossbeam 14, the supplementary lighting module also includes multiple fixing members 8. The multiple fixing members 8 are distributed along the extension direction of the second lamp tube 52. Each fixing member 8 can be detachably installed on the lamp housing 1. Each fixing member 8 is provided with a hook, and each fixing member 8 is hung on the lamp housing 1 by the hook.
[0040] When the operator needs to install the supplementary lighting module on the crossbeam 14, the fixing part 8 can be removed from the lamp housing 1 first, and then the fixing part 8 can be hung on the crossbeam 14. Finally, the hook of the fixing part 8 can be hung on the top of the lamp housing 1 to facilitate the installation of the supplementary lighting module.
[0041] The implementation principle of the supplementary lighting module in this application embodiment is as follows: The supplementary lighting module integrates top and side supplementary light sources 5 and is combined with an adjustable installation structure to achieve flexible switching between vertical and horizontal supplementary lighting directions. It can adapt to the supplementary lighting needs of different plant species or growth stages without disassembly and reinstallation, reducing labor costs and improving supplementary lighting efficiency. At the same time, the reflector 3, heat dissipation design and detachable fasteners 8 further optimize the light intensity, service life and installation convenience, solving the core problem of insufficient flexibility of traditional supplementary lights, and is suitable for diverse agricultural scenarios such as greenhouses.
[0042] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
