Description

Technical Field

[0001] This invention relates to the technical field of supplemental lighting equipment, and in particular to a plant supplemental lighting system. Background Technology

[0002] With the development of modern agricultural technology, optimizing the plant growth environment has become one of the key factors in improving crop yield and quality. Especially in cases of insufficient light or the need for stable production throughout the year, artificial lighting systems have become an important auxiliary means. Plant lighting systems simulate natural light conditions to provide plants with the necessary light source for photosynthesis, thereby promoting healthy plant growth and increasing yield.

[0003] Common supplemental lighting systems involve laying light strips or nets composed of light sources such as LED lights or fluorescent lights directly above the plants. The light sources are powered on to provide light to the plants, thus achieving the supplemental lighting effect. However, since supplemental lighting is carried out when sunlight is weakened, both sunlight and light sources provide light to the plants at the same time. The light emitted by the light source will be scattered over a large area and cannot be concentrated on the plants, resulting in a large amount of energy loss. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a plant supplemental lighting system, the specific technical solution of which is as follows:

[0005] A plant supplemental lighting system includes a long plate, a conveying channel, a first light guide tube, a second light guide tube, and an LED light source. The long plate is horizontal, and its cross-sectional shape along the length of the horizontal plane is arc-shaped. The arc-shaped opening of the long plate faces downward. Multiple arc-shaped light-transmitting mirrors are arranged on the lower arc surface of the long plate. The long plate is hollow inside, and light is conducted inside the long plate and passes through the arc-shaped light-transmitting mirrors to illuminate the plant downward. The first light guide tube is connected to the long plate through the conveying channel. A light-concentrating structure is arranged on the first light guide tube to concentrate sunlight and transmit it into the first light guide tube. The conveying channel diffuses and scatters the light into the long plate. The second light guide tube is installed at an angle on the outer wall of the first light guide tube and is connected to the first light guide tube. The LED light source is installed inside the second light guide tube.

[0006] The long plate, the conveying channel, the inner walls of the first light guide tube and the second light guide tube are all coated with a reflective coating.

[0007] Furthermore, it also includes a U-shaped base frame, with a long plate located inside the U-shaped base frame. Both ends of the long plate are equipped with sliding sleeves, which are vertically slidably mounted on the U-shaped base frame. The U-shaped base frame is equipped with a power unit for providing power for the movement of the sliding sleeves.

[0008] Furthermore, the light-concentrating structure includes a third light guide tube, a spherical light-concentrating plate, and a reflector. One end of the third light guide tube is slidably inserted into the first light guide tube. The spherical light-concentrating plate is fixed to the other end of the third light guide tube and is connected to the third light guide tube. The reflector is located inside the spherical light-concentrating plate and faces opposite directions to the reflector. The spherical light-concentrating plate and the reflector are connected by multiple connecting frames. When sunlight shines on the spherical light-concentrating plate, the spherical light-concentrating plate focuses and reflects the light onto the reflector, and the reflector vertically reflects the light into the third light guide tube.

[0009] Furthermore, the U-shaped base frame has a guide groove on its side wall, which consists of a conical opening, a vertical section, and an inclined section from top to bottom;

[0010] A rotating shaft is rotatably installed inside the first light guide tube. A shielding disc is installed on the rotating shaft. The end of the rotating shaft passes through the first light guide tube and extends out. The rotating shaft and the first light guide tube are connected by a torsion spring. A support arm is installed at the end of the rotating shaft. The length direction of the support arm is along the radial direction of the rotating shaft. A sliding column that cooperates with the guide groove is installed on the support arm.

[0011] Furthermore, a column, a resistor plate, and a guide sleeve are provided between the long plate and the U-shaped base frame. The column is vertically fixed on the long plate, the resistor plate is fixed on the column, and the guide sleeve is fixed on the U-shaped base frame. The resistor plate is vertically slidably inserted into the guide sleeve. A fixing groove is provided on the inner wall of the guide sleeve, and a conductive sheet is provided in the fixing groove.

[0012] The resistor plate is electrically connected to the LED light source.

[0013] Furthermore, the power unit includes a main shaft rotatably mounted on a U-shaped base frame, with a first adjusting arm fixed at both ends of the main shaft, a second adjusting arm rotatably mounted on the first adjusting arm, and the second adjusting arm rotatably connected to a sliding sleeve.

[0014] The U-shaped base frame is equipped with a motor that provides power for the rotation of the main shaft.

[0015] Furthermore, the inner wall of the long plate is provided with a reflective slope at one end of the conveying channel.

[0016] Furthermore, a light intensity meter is installed on the conveying channel.

[0017] The advantages of this invention are:

[0018] By allowing both sunlight and LED light to pass through the long board and illuminate the plants via curved light-transmitting mirrors, the system facilitates the concentration and independent transmission of light, preventing light from spreading randomly in the air and wasting energy. This method of isolating and concentrating light improves the light utilization rate when using LED supplemental lighting, thus ensuring the light intensity and quality required for plant growth. In summary, this plant supplemental lighting system, through its ingenious design, not only solves the problem of light loss in traditional supplemental lighting systems but also makes full use of natural light, reduces energy waste, and improves light efficiency and the quality of plant growth.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] In the description of this invention, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0031] like Figures 1 to 3As shown, a plant supplemental lighting system of the present invention includes a long plate 1, a conveying channel 3, a first light guide tube 4, a second light guide tube 5, and an LED light source 6. The long plate 1 is horizontal, and its cross-sectional shape along the length direction perpendicular to the length of the long plate 1 is arc-shaped. The arc-shaped opening of the long plate 1 faces downward. Multiple arc-shaped light-transmitting mirrors 2 are provided on the lower arc surface of the long plate 1. The long plate 1 is hollow inside, and light is conducted inside the long plate 1 and passes through the arc-shaped light-transmitting mirrors 2 to illuminate the plant downward. The first light guide tube 4 is connected to the long plate 1 through the conveying channel 3. The first light guide tube 4 is provided with a light-concentrating structure, which gathers sunlight and transmits it into the first light guide tube 4. The conveying channel 3 diffuses and scatters the light into the long plate 1. The second light guide tube 5 is installed obliquely on the outer wall of the first light guide tube 4 and is connected to the first light guide tube 4. The LED light source 6 is installed inside the second light guide tube 5.

[0032] Among them, the inner walls of the long plate 1, the conveying channel 3, the first light guide tube 4 and the second light guide tube 5 are all coated with a reflective coating.

[0033] In detail, each curved light-transmitting mirror 2 corresponds to a plant below it. In this way, the light in the long plate 1 can shine downwards onto the plant through the curved light-transmitting mirror 2, thereby providing a light source for the plant. The setting of multiple curved light-transmitting mirrors 2 can output light at a designated position, thereby avoiding the random dispersion of light and causing energy waste. Since the cross-sectional shape of the long plate 1 is curved, it is easy to concentrate the light on the plant. The shape of the conveying channel 3 is bucket-shaped, and the light inside it can diffuse into the long plate 1, thus avoiding the light from concentrating in the long plate 1 and making it easy to transmit light evenly in the long plate 1. Since the second light guide tube 5 is tilted, it is easy for the light emitted by the LED light source 6 to tilt downwards and enter the conveying channel 3 and the long plate 1, avoiding the light from entering the first light guide tube 4 upwards and being discharged through the top of the first light guide tube 4, thus reducing light loss.

[0034] In use, the light-concentrating structure gathers sunlight and transmits it to the long plate 1 through the first light guide tube 4 and the conveying channel 3. The conveying channel 3 diffuses the light into the long plate 1, making the light uniform within the long plate 1. The light propagates along the length of the long plate 1. When the light moves to the position of the arc-shaped light-transmitting mirror 2, some of the light can shine down onto the plant through the arc-shaped light-transmitting mirror 2, allowing the plant to receive the light and carry out normal photosynthesis. When the sunlight weakens, the light received by the light-concentrating structure weakens. At this time, the LED light source 6 is powered on and emits light. The light enters the first light guide tube 4 and propagates to the long plate 1 through the conveying channel 3, thereby supplementing the light within the long plate 1 and ensuring that the plant always has sufficient light.

[0035] By ensuring that both sunlight and light from the LED light source 6 can reach the plants through the long plate 1 and be projected onto them via the curved light-transmitting mirror 2, the system facilitates the concentration and independent transmission of light, preventing light from spreading randomly in the air and wasting energy. This method of isolating and concentrating light improves the light utilization rate when supplementing light with the LED light source 6, thus ensuring the light intensity and quality required for plant growth. In summary, this plant supplementary lighting system, through its ingenious design, not only solves the problem of light loss in traditional supplementary lighting systems but also makes full use of natural light, reduces energy waste, and improves light efficiency and the quality of plant growth.

[0036] like Figure 1 As shown, it also includes a U-shaped base frame 7, with a long plate 1 located inside the U-shaped base frame 7. Both ends of the long plate 1 are provided with sliding sleeves 8, which are vertically slidably mounted on the U-shaped base frame 7. The U-shaped base frame 7 is provided with a power unit for providing power for the movement of the sliding sleeves 8.

[0037] In detail, the plant is located inside the U-shaped base 7. The light emitted by the multiple arc-shaped light-transmitting mirrors 2 on the long plate 1 can shine on the plant. When the sunlight is sufficient, in order to avoid damage to the plant due to excessive light intensity, the long plate 1 can be moved upward by the power unit and the distance between the long plate 1 and the plant can be adjusted. When the light is weak, the long plate 1 can be moved downward by the power unit and the distance between it and the plant can be reduced, thereby providing sufficient light for the plant. When the long plate 1 moves, it drives the sliding sleeve 8 to slide on the U-shaped base 7.

[0038] like Figure 3 As shown, the light-concentrating structure includes a third light guide tube 9, a spherical light-concentrating plate 10, and a reflector 11. One end of the third light guide tube 9 is slidably inserted into the first light guide tube 4. The spherical light-concentrating plate 10 is fixed to the other end of the third light guide tube 9 and is connected to the third light guide tube 9. The reflector 11 is located inside the spherical light-concentrating plate 10, and the spherical light-concentrating plate 10 and the reflector 11 are in opposite directions. The spherical light-concentrating plate 10 and the reflector 11 are connected by multiple connecting frames 12. When sunlight shines on the spherical light-concentrating plate 10, the spherical light-concentrating plate 10 concentrates and reflects the light onto the reflector 11, and the reflector 11 reflects the light vertically into the third light guide tube 9.

[0039] In detail, the positions of the third light guide tube 9 and the spherical light-concentrating plate 10 are fixed. When the long plate 1 moves, the third light guide tube 9 and the first light guide tube 4 will slide relative to each other. The reflector 11 is supported by multiple connecting frames 12. When sunlight shines on the spherical light-concentrating plate 10, the inner wall of the spherical light-concentrating plate 10 will focus and reflect the light into the reflector 11. The reflector 11 will then reflect the light vertically downwards into the third light guide tube 9 and the first light guide tube 4, thereby achieving the focusing and propagation of light.

[0040] like Figures 3 to 4 As shown, the U-shaped base frame 7 has a guide groove 13 on its side wall. The guide groove 13 consists of a conical opening, a vertical part, and an inclined part from top to bottom.

[0041] A rotating shaft 14 is rotatably disposed inside the first light guide tube 4. A shielding disc 15 is disposed on the rotating shaft 14. The end of the rotating shaft 14 passes through the first light guide tube 4 and extends out. The rotating shaft 14 and the first light guide tube 4 are connected by a torsion spring 16. A support arm 17 is disposed at the end of the rotating shaft 14. The length direction of the support arm 17 is along the radial direction of the rotating shaft 14. A sliding column 18 that cooperates with the guide groove 13 is disposed on the support arm 17.

[0042] In detail, the torsion spring 16 provides elastic force to the rotating shaft 14. In its natural state, the support arm 17 is vertically downward, and the light-shielding disc 15 is vertical. At this time, the light in the first light guide tube 4 propagates normally. As the light intensity decreases, the long plate 1 gradually moves downward, and the first light guide tube 4 moves downward synchronously. The sliding column 18 gradually enters the conical opening and the vertical part on the guide groove 13. The conical opening facilitates the smooth entry of the sliding column 18 into the guide groove 13. At this time, the light-shielding disc 15 remains vertical. When there is no more light, the sliding column 18 slides into the guide groove 13. Inside the inclined section of the groove 13, the sliding column 18 moves horizontally. The sliding column 18 drives the shielding disc 15 to rotate through the support arm 17 and the rotating shaft 14. The shielding disc 15 blocks the first light guide tube 4, and the light-gathering structure no longer receives sunlight. Part of the light emitted by the LED light source 6 enters the first light guide tube 4, and after being blocked by the shielding disc 15, it enters the long plate 1 in the opposite direction, thereby reducing the loss of light. During the day, the light intensity gradually increases, the first light guide tube 4 and the long plate 1 gradually move upward, and the shielding disc 15 returns to the vertical state.

[0043] like Figure 5 As shown, a column 19, a resistor plate 20, and a guide sleeve 21 are provided between the long plate 1 and the U-shaped base frame 7. The column 19 is vertically fixed on the long plate 1, the resistor plate 20 is fixed on the column 19, and the guide sleeve 21 is fixed on the U-shaped base frame 7. The resistor plate 20 is vertically slidably inserted into the guide sleeve 21. A fixing groove is provided on the inner wall of the guide sleeve 21, and a conductive sheet 22 is provided in the fixing groove.

[0044] Among them, the resistor plate 20 is electrically connected to the LED light source 6.

[0045] In detail, when the long plate 1 moves down, the column 19 and the resistor plate 20 move down synchronously. When the resistor plate 20 contacts the conductive sheet 22, external energy supplies power to the LED light source 6 through the conductive sheet 22 and the resistor plate 20. At this time, the LED light source 6 lights up. As the resistor plate 20 moves down, the effective conductive length on the resistor plate 20 gradually decreases, the circuit current intensity gradually increases, and the light emitted by the LED light source 6 gradually increases. As the light intensity decreases, the long plate 1 moves down and the brightness of the LED light source 6 gradually increases. When the resistor plate 20 separates from the conductive sheet 22, the LED light source 6 is de-energized.

[0046] like Figure 1 As shown, the power unit includes a main shaft 23 rotatably mounted on a U-shaped base frame 7. Both ends of the main shaft 23 are fixed with first adjusting arms 24. A second adjusting arm 25 is rotatably mounted on the first adjusting arm 24. The second adjusting arm 25 is rotatably connected to the sliding sleeve 8.

[0047] The U-shaped base frame 7 is equipped with a motor 26 that provides power for the rotation of the main shaft 23.

[0048] In detail, the motor 26 can drive the two first adjusting arms 24 to tilt synchronously and in the same direction through the main shaft 23. The first adjusting arms 24 drive the sliding sleeve 8 to move up and down through the second adjusting arm 25, thereby providing power for the position adjustment of the long plate 1.

[0049] like Figure 6 As shown, the inner wall of the long plate 1 is provided with a reflective slope 27 at one end of the conveying channel 3.

[0050] In detail, the reflective slope 27 corresponds to the position of the conveying channel 3. The light transmitted by the conveying channel 3 can enter the long plate 1 through the reflection of the reflective slope 27, thereby preventing the light from re-entering the conveying channel 3 and facilitating the guidance of the direction of light propagation.

[0051] like Figure 6 As shown, a light intensity meter 28 is installed on the conveying channel 3.

[0052] In detail, by setting up a light intensity meter 28, the light intensity transmitted from the conveying channel 3 to the long plate 1 can be easily detected, thereby controlling the motor 26 to run and adjusting the position of the long plate 1 through an external controller or other control unit.

[0053] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
