Description

Technical Field

[0001] The invention relates to the technical field of lighting, and in particular to a plant supplementary lighting device. Background Art

[0002] Plant fill light is a plant growth auxiliary lamp that uses semiconductor lighting principles and is specially used for the production of flowers, vegetables and other plants, combining high-precision technology. Generally, indoor plants and flowers will grow worse and worse over time, mainly because of the lack of light exposure. Through the irradiation of LED lights suitable for the spectrum required by plants, it can not only promote their growth, but also prolong the flowering period and improve the quality of flowers. Further application of this high-efficiency light source system to agricultural production such as greenhouses and other facilities can, on the one hand, solve the problem of insufficient sunlight leading to a decline in the taste of greenhouse vegetables such as tomatoes and cucumbers. On the other hand, it can also make winter greenhouse eggplant and fruit vegetables available on the market around the Spring Festival, thereby achieving the purpose of off-season cultivation.

[0003] Existing plant fill-in lights generally use multiple light strips for fill-in lighting, but the emission angle of the light emitted by the light strips is generally fixed, and the emission angles of the light of these light strips are basically the same, all irradiating vertically downward above the plants. This will limit the light emission angle of the plant fill-in light, resulting in a small light emission angle and a small light coverage area, making it inconvenient to adjust the lighting range of the lamp, and it is also inconvenient to store the lamp when not needed. Therefore, there is an urgent need to invent a plant fill-in lighting device to solve the above problems. Summary of the invention

[0019] (III) Beneficial effects

[0020] Compared with the prior art, the present invention provides a plant supplementary lighting device, which has the following beneficial effects:

[0021] 1. The plant supplementary lighting device can conveniently adjust the angle of the second reflector in each lighting assembly through the angle adjustment component, thereby changing the irradiation range of the lighting lamp under the first reflector, and can also conveniently reduce the angle between the second reflectors for easy storage. The distance adjustment component and the connecting component can conveniently change the distance between the lighting assemblies. The change of the distance between the lighting assemblies can conveniently change the irradiation range of the lighting lamp. The three lighting lamps can be conveniently coordinated with the angle adjustment component to change the overall and local irradiation range, making the adjustment more flexible. At the same time, changing the distance between the lighting lamps is more conducive to storage.

[0022] 2. The plant supplementary lighting device is provided with an angle adjustment component. When the movable rod moves up and down, it drives the connecting block to move up and down. When the connecting block moves up and down, it drives the upper end of the third connecting rod to move up and down through the shafts at both ends of the connecting block. At this time, the lower end of the third connecting rod drives the second connecting shaft to move through the third connecting hole. When the second connecting shaft moves, it drives the first connecting shaft at the upper end of the second reflector to rotate in the connecting ring, so that the second reflector rotates around the first connecting shaft, so that the opening angles of the second reflectors on both sides below the first reflector change, thereby adjusting the irradiation range of the lighting lamp below the first reflector, and also conveniently storing the second reflector.

[0023] 3. The plant supplementary lighting device is provided with movable limiting fins. When the first knob is rotated, the angle adjustment rod is driven to rotate. When the angle adjustment rod is rotated, the first limiting block fixedly installed at the bottom of the angle adjustment rod is driven to rotate in the first connecting groove. When the angle adjustment rod is rotated, the movable plate is driven to move up and down through the second connecting hole threadedly engaged with the angle adjustment rod. When the movable plate moves up and down, the movable rod is driven to move up and down. The movable rod moves up and down in the first connecting hole on the first connecting rod. When the movable plate moves up and down, the movable limiting fins at the four corners of the movable plate move up and down in the movable groove on the second connecting rod. The second connecting rod limits the movable plate when it moves, thereby maintaining its stability.

[0024] 4. The plant supplementary lighting device is provided with a distance adjustment component. When the second knob is turned, the second knob will drive the distance adjustment rod to rotate. When the distance adjustment rod rotates, the third limit blocks at both ends of the distance adjustment rod will rotate in the first rotation groove. When the distance adjustment rod rotates in the first rotation groove, the third limit blocks can limit the distance adjustment rod in the first rotation groove. The rotation of the distance adjustment rod will drive the movable connection block to move through the fourth connection hole engaged with the thread on the distance adjustment rod. Since the movable connection blocks are distributed in a mirror-symmetrical manner with respect to the center position of the distance adjustment rod, and the distance adjustment rod is provided with a mirror-symmetrical thread about the center, when the distance adjustment rod rotates, the two movable connection blocks will be moved closer or farther away, and the movable connection block moves When the fifth connecting rod moves, the sixth connecting hole at one end of the fifth connecting rod will rotate around the connecting rod in the connecting rod, and the other end of the fifth connecting rod will rotate around the fourth connecting rod on the fourth connecting rod. Thus, the angle between the two fifth connecting rods can be changed synchronously, and the distance between the fourth connecting rod and the connecting rod can be changed at the same time, so as to conveniently change the illumination range of the lighting lamp. With the help of the angle adjustment component, the three lighting lamps can be conveniently coordinated to change the overall and local illumination ranges, making the adjustment more flexible. At the same time, changing the distance between the lighting lamps is more conducive to storage.

[0025] 5. The plant supplementary lighting device is provided with a fifth connecting rod, so that the fourth connecting rod drives the second fixed plate to move, the movement of the second fixed plate drives the second connecting rod to move, the movement of the second connecting rod drives the first reflector to move, the movement of the first reflector drives the lighting lamp to move, thereby changing the illumination range of the lighting lamp.
