[0032] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0033] like Figures 1-14 As shown, a multispectral lighting fixture for crops in a greenhouse includes a base 1; and also includes: The first spectral lamp 2 is installed at the bottom center of the base 1; Multiple second-spectrum lamps 3 are arranged in a ring array around the bottom perimeter of the base 1, such as... Figures 1-4 As shown, the number of second-spectrum lamps 3 can be three, and different numbers can be used in specific implementations; the second-spectrum lamps 3 are equipped with lamp bodies with adjustable spectral colors; One end of the second spectral lamp 3 is provided with an end seat 5, which is hinged to the base 1 and connected to a flipping mechanism. The flipping mechanism is used to drive the second spectral lamp 3 to rotate 90 degrees up and down for adjustment.

[0034] The first-spectrum lamp 2 emits light of the first spectrum; it can be an ultraviolet lamp or a regular incandescent lamp. The second-spectrum lamp 3 emits light of the second spectrum. Both spectra work simultaneously to aid the growth of crops inside the greenhouse.

[0035] Furthermore, the first spectrum lamp 2 can be a lamp that emits ultraviolet (UVB) wavelength light, which can sterilize crops by providing them with UVB wavelength light, thus helping the crops grow in many ways.

[0036] The second-spectrum lamp 3 uses a lamp body with adjustable spectral color, which can be adjusted according to the growth cycle of crops.

[0037] The second spectrum lamp 3 has a strip-shaped structure and can be rotated 90 degrees up and down for adjustment, such as... Figures 1-2 As shown, the illumination angle can be adjusted according to the location of the crops to meet different illumination angle requirements.

[0038] like Figure 3 As shown, the lamp body inside the second spectrum lamp 3 is composed of multiple first lamp beads 301, multiple second lamp beads 302 and multiple third lamp beads 303, and the multiple first lamp beads 301, multiple second lamp beads 302 and multiple third lamp beads 303 are evenly distributed inside the second spectrum lamp 3.

[0039] The first LED chip 301, the second LED chip 302, and the third LED chip 303 constitute a multi-chip LED light. These three chips are red, green, and blue LEDs, respectively. Using a dimmer or intelligent control system, the current intensity of the red, green, and blue chips is adjusted to achieve spectral color regulation, meeting the light requirements of different growth stages. For example, during the germination stage of crops, blue light is used to promote seed germination and seedling formation. Other spectral colors are adjusted accordingly during other growth stages of crops, and so on. Using LED lights is more energy-efficient and effective.

[0040] like Figure 2 , Figure 4 and Figure 6 As shown, the base 1 is composed of an upper shell 102 and a lower shell 101. The upper shell 102 and the lower shell 101 form a plurality of grooves 105 arranged in a ring array, and a first side groove 103 and a second side groove 104 connecting to both sides of the grooves 105; the end seat 5 is embedded in the grooves 105.

[0041] like Figure 8 As shown, a side cylinder 15 is fixed to one side of the end seat 5, and the side cylinder 15 is rotatably connected to the mounting seat 16 fixedly installed in the first side groove 103. The side cylinder 15 communicates with the end seat 5. The flipping mechanism includes a motor 8 and a fixing plate 12. The motor 8 and the fixing plate 12 are coaxially arranged with the side cylinder 15. The motor 8 is cylindrical and is fixedly installed in the second side groove 104. A circular hole is opened on the side of the end seat 5 away from the side cylinder 15. The motor 8 passes through the circular hole and enters the end seat 5. A connecting frame 1201 is fixed to the fixing plate 12. The connecting frame 1201 is fixed to the end seat 5.

[0042] like Figure 9 As shown, it also includes a rotating mechanism; the rotating mechanism is used to drive the second spectrometer lamp 3 to rotate and adjust its position around its length axis by 360 degrees; the rotating mechanism includes a transmission mechanism 10; a fixed inner plate 501 is fixedly installed inside the end seat 5, and the transmission mechanism 10 includes a rotating tube 1003 rotatably installed on the fixed inner plate 501; the rotating tube 1003 is fixedly connected to one end of the second spectrometer lamp 3, and a second bevel gear 1002 is fixedly sleeved on one end of the rotating tube 1003 located inside the end seat 5, the second bevel gear 1002 is meshed with a first bevel gear 1001, and a cylinder sleeved on the output shaft 801 of the motor 8 is provided in the middle of the first bevel gear 1001, and the cylinder is rotatably connected to a fixed frame 1004 fixedly installed inside the end seat 5.

[0043] like Figure 7As shown, it also includes a switching assembly 13 disposed between the fixed disk 12 and the first bevel gear 1001. The switching assembly 13 is connected to a translation mechanism 7, and the switching assembly 13 is slidably sleeved with a square post 17 fixedly mounted on the output shaft 801. The translation mechanism 7 is used to drive the switching assembly 13 to move along the axial direction of the output shaft 801, so that the output shaft 801 is switched to be connected with the fixed disk 12 and the first bevel gear 1001 through the switching assembly 13.

[0044] like Figure 2 As shown, the switching assembly 13 includes a sleeve 1301; a square groove is provided at the axis of the sleeve 1301, and the square groove is connected to the square column 17 with clearance fit; a side frame 1302 is fixed on one side of the sleeve 1301; elastic rods are provided on both sides of the side frame 1302, and the elastic rods include an outer cylinder 1304 fixedly installed on the side frame 1302 and a first spring 1306 disposed in the outer cylinder 1304; a movable insert 1305 is slidably installed on the outer cylinder 1304, and one end of the movable insert 1305 located in the outer cylinder 1304 is elastically connected to the inner end face of the outer cylinder 1304 through the first spring 1306; a plurality of arc-shaped grooves 22 distributed in a ring array are provided on the side of the fixed disk 12 facing the switching assembly 13 and the side of the first bevel gear 1001 facing the switching assembly 13.

[0045] The switching component 13 is driven by the translation mechanism 7 to move, and the sleeve 1301 slides on the square post 17. Before and after the switching component 13 moves, the sleeve 1301 is always connected to the square post 17. When the switching component 13 moves closer to the fixed plate 12, the movable insert 1305 on the side closer to the fixed plate 12 is inserted into the arc-shaped groove 22 on the fixed plate 12, or the movable insert 1305 is blocked by the side wall of the fixed plate 12 (i.e., the position between two adjacent arc-shaped grooves 22), so that the movable insert 1305 is pressed against the fixed plate 12. Inside the outer cylinder 1304, the first spring 1306 is compressed; the movable insert 1305 is located in the arc-shaped groove 22, the motor 8 drives the square column 17 to rotate through the output shaft 801, and the entire switching assembly 13 rotates together with the square column 17. The movable insert 1305 on the switching assembly 13 moves in the arc-shaped groove 22 until it is in contact with one end of the groove wall of the arc-shaped groove 22. The above rotation continues, and the movable insert 1305 pushes the fixed plate 12 to drive the end seat 5 and the second spectrum lamp 3 to rotate together, so that the second spectrum lamp 3 is in such a position as Figures 1-2The system allows for switching between two states. When the movable insert 1305 is positioned between the two arc-shaped slots 22, it drives the switching assembly 13 to rotate. The movable insert 1305 moves between the two arc-shaped slots 22, and after moving onto one of them, the spring force of the first spring 1306 causes the movable insert 1305 to insert into the arc-shaped slot 22. Then, it continues to rotate, and the movable insert 1305 pushes the second spectral lamp 3 to rotate and adjust. In the above description, the switching assembly 13 is connected to the fixed plate 12.

[0046] The switching assembly 13 is driven by the translation mechanism 7 to move closer to the first bevel gear 1001. The movable insert 1305 on the side closest to the first bevel gear 1001 is inserted into the arc-shaped groove 22, or the movable insert 1305 is blocked by the side wall of the first bevel gear 1001 (i.e., between adjacent arc-shaped grooves 22), causing the movable insert 1305 to be pressed into the outer cylinder 1304 and compress the first spring 1306. When the movable insert 1305 is in the arc-shaped groove 22, the motor 8 drives the square column 17 to rotate via the output shaft 801. The entire switching assembly 13 rotates together with the square column 17, and the movable insert 13... The insert block 1305 moves within the arc-shaped groove 22 until it contacts one end of the groove wall. It then continues to rotate, pushing the first bevel gear 1001 to rotate. When the movable insert block 1305 is positioned between two arc-shaped grooves 22, it drives the switching assembly 13 to rotate. The movable insert block 1305 moves between two arc-shaped grooves 22, and after moving onto one, it is inserted into the groove by the force of the first spring 1306. It then continues to rotate, pushing the first bevel gear 1001 to rotate. In this process, the switching assembly 13 is connected to the first bevel gear 1001.

[0047] When the first bevel gear 1001 is driven to rotate, the meshing transmission between the first bevel gear 1001 and the second bevel gear 1002 causes the rotating tube 1003 to drive the second spectral lamp 3 to rotate 360 ​​degrees around its axis with its length direction as the axis direction, thereby realizing that the second spectral lamp 3, in addition to the above, can also rotate in other directions. Figures 1-2 In addition to the 90-degree vertical rotation shown, the above-mentioned rotation adjustment is also performed. This is suitable for situations where crops have grown taller than the light fixture, allowing for rotation adjustment so that the luminous side faces the crops above.

[0048] The switching component 13 is connected to the first bevel gear 1001 and the fixed plate 12, so that the two flip adjustments of the second spectrum lamp 3 can be driven by a single motor 8 without the need for too many power components.

[0049] like Figure 8As shown, the translation mechanism 7 includes an electric push rod 701 fixedly installed in the first side groove 103. The output end of the electric push rod 701 is fixed with a connecting rod 704, and the connecting rod 704 passes through the hole in the middle of the side cylinder 15 and the fixed plate 12. The connecting rod 704 is rotatably connected to the end of the sleeve 1301. A guide strip 702 is fixedly installed on the output end of the electric push rod 701. The guide strip 702 is slidably sleeved with the guide sleeve 703 fixedly installed on the shell wall of the electric push rod 701.

[0050] The extension and retraction of the electric push rod 701 drives the connecting rod 704 to move, and the connecting rod 704 drives the switching component 13 to move. During the movement, the guide bar 702 and the guide sleeve 703 provide guidance.

[0051] The connecting rod 704 is rotatably connected to the sleeve 1301. When the sleeve 1301 rotates, the connecting rod 704 does not rotate with the sleeve 1301.

[0052] To ensure the stability of the second spectrum lamp 3 after flipping and adjustment, a shaft damper is provided between the side cylinder 15 and the mounting base 16 and between the rotating tube 1003 and the fixed inner plate 501 to provide a limit after flipping.

[0053] Meanwhile, in order to determine the flip angle of the second spectrum lamp 3, angle sensors are installed between the side cylinder 15 and the mounting base 16 and between the rotating tube 1003 and the fixed inner plate 501, and feedback signals are provided through the angle sensors.

[0054] A first sealing ring 6 is provided on one side of the end seat 5. The first sealing ring 6 fits against the side wall of the groove 105 near the first side groove 103. A second sealing ring 9 is provided on the circular hole wall on the other side of the end seat 5. The inner ring of the second sealing ring 9 fits against the outer shell of the motor 8. Both the first sealing ring 6 and the second sealing ring 9 are inflatable sealing rings, and both the first sealing ring 6 and the second sealing ring 9 are connected to a connecting pipe 14. The connecting pipe 14 is arranged inside the end seat 5. The connecting pipe 14 is connected to an inflation assembly 18, and the inflation assembly 18 is installed on the inner wall of the end seat 5.

[0055] The inflation assembly 18 includes a pressure-bearing column 1802 and a connecting seat 1803 fixedly installed on the inner wall of the end seat 5. An air cylinder 1801 is fixedly installed on the connecting seat 1803. A piston sleeve 1804 is fitted inside the air cylinder 1801. The piston sleeve 1804 is fixedly sleeved with one end of the pressure-bearing column 1802 located inside the air cylinder 1801. The piston sleeve 1804 and the inner wall of the air cylinder 1801 form an air injection chamber, and a second spring 1805 is provided inside the air injection chamber. The pressure-bearing column 1802 is elastically connected to the inner end face of the air cylinder 1801 through the second spring 1805. The air injection chamber is connected to the connecting pipe 14. A pressure ring 11 is fitted to one end face of the pressure-bearing column 1802 located outside the air cylinder 1801. The pressure ring 11 is fixed to the side frame 1302 through a connecting block 1303.

[0056] The first sealing ring 6 and the second sealing ring 9 provide a seal for the interior of the end seat 5 and the first side groove 103, improving dustproof and waterproof performance. The inflation component 18 is provided to further enhance the sealing effect.

[0057] Among them, such as Figure 12 As shown, when the switching component 13 is connected to the first bevel gear 1001, the pressure-bearing column 1802 is subjected to the pressure of the pressure ring 11 and is drawn into the air cylinder 1801. The piston compresses the air injection chamber in the air cylinder 1801 and compresses the second spring 1805. The gas in the air injection chamber is injected into the first sealing ring 6 and the second sealing ring 9 through the connecting pipe 14, causing them to expand and improve the sealing effect. At this time, the motor 8 can be used to drive the second spectral lamp 3 to rotate around its own length axis. The end seat 5 does not rotate, and the first sealing ring 6 and the second sealing ring 9 do not rub against the wall of the groove 105 and the wall of the motor 8 housing.

[0058] In the above state, the switching assembly 13 moves closer to the fixed disk 12, establishing a connection between the switching assembly 13 and the fixed disk 12. The switching assembly 13 drives the pressure ring 11 to move together, and the pressure ring 11 separates from the pressure column 1802. Through the elastic force of the second spring 1805, the pressure column 1802 and the piston sleeve 1804 move together, increasing the volume of the air injection chamber. The gas in the first sealing ring 6 and the second sealing ring 9 is drawn through the connecting pipe 14, causing the first sealing ring 6 and the second sealing ring 9 to contract. When the motor 8 drives the end seat 5 to rotate, the wear of the first sealing ring 6 and the second sealing ring 9 can be reduced.

[0059] Through the above design, when the drive end seat 5 rotates, the first sealing ring 6 and the second sealing ring 9 contract, reducing wear. When the drive end seat 5 does not need to rotate, the first sealing ring 6 and the second sealing ring 9 expand, ensuring improved sealing performance.

[0060] The upper housing 102 and the lower housing 101 form a cavity, and the main control module 4 is disposed within the cavity. Figure 4 As shown, the power connector on the top of the main control module 4 connects to an external power source, while the power connector on the bottom of the main control module 4 connects to the first spectrometer lamp 2. The main control module 4 has two sets of drive circuits: one connected to the first spectrometer lamp 2 for control, and the other connected to the lamp body of the second spectrometer lamp 3 for control. The upper housing 102 and the lower housing 101 are fixed together with screws, and a sealing element is provided between the bottom surface of the upper housing 102 and the top surface of the lower housing 101 to ensure the waterproof sealing of the cavity formed by the two housings.

[0061] A junction box 19 is installed inside the end bracket 5. The circuit board inside the junction box 19 is connected to the main control module 4 via wires 401. Figures 4-5 As shown, the wire 401 is reserved with sufficient length in the first side groove 103. When the end seat 5 drives the second spectrum lamp 3 to rotate up and down by 90 degrees, the wire 401 will not cause dragging and affect the rotation.

[0062] like Figure 11 As shown, the circuit board inside the junction box 19 is electrically connected to a socket 20. The socket 20 is fixed to the junction box 19 by a support rod, and the socket 20 is coaxial with the rotating tube 1003. A cable 304 is fixedly installed at the axis of the rotating tube 1003, and the cable 304 is encased in a rigid tube to give it rigidity. The cable 304 connects the lamp body of the second spectrum lamp 3 to the plug 21, which is inserted into the socket 20. Both the plug 21 and the socket 20 are round, ensuring electrical connection even under relative rotation. In summary, the lamp body of the second spectrum lamp 3 is electrically connected to the main control module 4 through the cable 304, plug 21, socket 20, circuit board inside the junction box 19, and wire 401. The main control module 4 controls the second spectrum lamp 3 through a set of drive circuits. Specifically, this set of drive circuits adjusts the spectral color of the lamp body through a dimmer or intelligent control system.

[0063] The motor 8 and electric push rod 701 are directly electrically connected to the main control module 4, which controls them. The angle sensor on the rotating tube 1003 is connected to a circuit board in the junction box 19, and is electrically connected to the main control module 4 via the circuit board and wire 401. The angle sensor on the side cylinder 15 is also directly electrically connected to the main control module 4.
