DETAILED DESCRIPTION

[0035] A specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation.

[0036] like Figures 1 to 10 As shown, an LED fill light illumination system equipped with an optical sensor provided in an embodiment of the present invention comprises a lighting bracket 1 and a plurality of LED lamps 2 arranged on the lighting bracket 1, and also comprises a moving mechanism for adjusting the distance between the lighting bracket 1 and the plant stand, and the lighting bracket 1 is also provided with an adjusting device 1 and an adjusting device 2 for adjusting the irradiation angle of the LED lamp 2;

[0037] A plurality of lamp stands 3 are rotatably mounted on the lighting bracket 1, a mounting shaft 4 is rotatably provided on the lamp stand 3, the LED lamp 2 is provided on the mounting shaft 4, the adjusting device 1 can drive the plurality of lamp stands 3 to rotate synchronously, and the adjusting device 2 can drive the plurality of mounting shafts 4 on the plurality of lamp stands 3 to rotate synchronously;

[0038] The moving mechanism includes a guide rail 5 installed on the ground, a first cylinder 6 fixedly installed on the lighting bracket 1, and an optical sensor 7 installed on the top of the lighting bracket 1, wherein the optical sensor 7 is electrically connected to the first cylinder 6, and the extended end of the first cylinder 6 is fixedly installed on a baffle connected to the guide rail 5;

[0039] The vertical plate part of the lighting bracket 1 is made of transparent material, which can reduce the obstruction of sunlight;

[0040] When the sunlight intensity is weak or high but does not exceed the light intensity required for the rapid growth of Dendrobium, the optical sensor 7 sends a signal to the controller, and the controller receives the signal and starts the first cylinder 6, so that the lighting bracket 1 is closer to the Dendrobium; when the sunlight intensity increases but does not exceed the light intensity required for the rapid growth of Dendrobium, the optical sensor 7 sends a signal to the controller, and the controller receives the signal and starts the first cylinder 6, so that the lighting bracket 1 is away from the Dendrobium;

[0041] Since the growth rates of different dendrobium plants are not exactly the same, and the straightness of the plants is not exactly the same, it is necessary to adjust the angles of some LED lamps separately. Figure 2 As shown, a mounting seat for fixing the LED lamp 2 is arranged on the mounting shaft 4, and the mounting seat includes a seat body 11, a connecting block 12 rotatably arranged at one end of the seat body 11, and a rotating drum 13 fixedly connected to the other end of the seat body 11;

[0042] The LED lamp 2 is fixedly mounted on the connecting block 12 by means of bolts;

[0043] The rotating drum 13 is sleeved on the mounting shaft 4;

[0044] The seat body 11 is also hinged with a pressure plate 14, and the rotating drum 13 is provided with a groove for making way for the pressure plate 14. The seat body 11 is also equipped with a spring, one end of which is connected to the pressure plate 14 and the other end is connected to the seat body 11. One end of the pressure plate 14 is pressed against the mounting shaft 4 under the action of the spring.

[0045] like Figure 2 As mentioned above, two pressing plates 14 are symmetrically arranged on the seat body 11;

[0046] Press down one end of the pressing plate 14 located above the lampshade of the LED lamp 2, and the other end of the pressing plate 14 can be lifted up, and the pressing plate 14 is separated from the mounting shaft 4. At this time, the mounting shaft 4 can be rotated at any angle, and it can be automatically fixed by the spring when the hand is released;

[0047] The adjusting device is a first motor 21 used to drive the installation shaft 4 to rotate. The first motor 21 is fixedly mounted on the lamp holder 3. The upper and lower installation shafts 4 are connected by a belt transmission mechanism 22.

[0048] A transmission mechanism for connecting two mounting shafts 4 on a coaxial line is provided between each two adjacent lamp stands 3;

[0049] The second adjustment device is a second motor 23 fixedly installed in the base of the lighting bracket 1, the output shaft of the second motor 23 is drivingly connected to the central axis of one of the lamp brackets 3, and every two adjacent central axes are drivingly connected via a belt transmission mechanism 22;

[0050] The transmission mechanism includes two transmission groups symmetrically arranged, and the transmission group includes a connecting rod 24 fixedly connected to the mounting shaft 4, a connecting shaft 25 sleeved on the connecting rod 24, a sleeve 26 fixedly installed on the connecting shaft 25, a connecting plate 27 for connecting a plurality of sleeves 26, and a second cylinder 28 connected and fixedly installed on the lamp holder 3, and the extended end of the second cylinder 28 is fixedly connected to the connecting plate 27;

[0051] The transmission mechanism can mutually transmit the multiple installation shafts 4 located on the same axis, and can separate the insertion rod 29 from the insertion hole by driving the second cylinder 28 before the lamp holder 3 rotates, so as to avoid affecting the rotation of the lamp holder 3;

[0052] The connecting shaft 25 can move back and forth along the length direction of the connecting rod 24;

[0053] An insertion rod 29 is fixedly connected to the end of the connecting shaft 25 of one of the transmission groups, and a socket 30 cooperating with the insertion rod 29 is opened at the end of the connecting shaft 25 of the other transmission group.

[0054] The pressing plate 14 is provided with an arc-shaped groove matched with the mounting shaft 4 , and a plurality of rubber strips for increasing friction are fixedly installed in the arc-shaped groove.

[0055] A cleaning pipe 8 is provided at the center position of every four LED lamps 2. Four nozzles are provided at the end of the cleaning pipe 8. The four nozzles are respectively directed toward the four LED lamps 2. The cleaning pipe 8 is connected to the vertical plate part of the lighting bracket 1. A water cavity is provided in the vertical plate part, and the water cavity is connected to a water inlet pipe.

[0056] Working principle: When in use, the optical sensor 7 senses the sunlight intensity in real time. When the sunlight intensity changes, the first cylinder 6 drives the lighting bracket 1 away from or close to the dendrobium, thereby providing the most suitable lighting environment for the dendrobium;

[0057] As the Dendrobium grows, the height of the Dendrobium plant gradually increases, and the illumination angle of the LED lamp 2 needs to be adjusted, which can be adjusted using the adjustment device 1 or the adjustment device 2 according to the needs;

[0058] When the adjustment device 1 is used, the first motor 21 is started, and under the action of the belt transmission mechanism 22 and the transmission mechanism between the two installation shafts 4, the multiple installation shafts 4 rotate simultaneously, thereby completing the adjustment of one angle of the LED lamp 2;

[0059] When the second adjustment device is used, the second cylinder 28 of the transmission mechanism is first started, and the second cylinder 28 drives the connecting plate 27 to move, so that the insertion rod 29 is pulled out of the insertion hole 30, and then the second motor 23 is started. The second motor 23 drives the multiple lamp holders 3 to rotate simultaneously under the transmission of the belt transmission mechanism 22, thereby completing the adjustment of another angle of the LED lamp 2;

[0060] After completing the angle adjustment twice, if one or more LED lamps 2 need to be adjusted in angle because the straightness or height of a plant is different from that of other plants, firstly, the LED lamp 2 is directly rotated around the axis connected to the connecting block 12 to adjust the angle; secondly, one end of the pressing plate 14 on the LED lamp 2 whose angle is to be adjusted is pressed, so that the other end of the pressing plate 14 is tilted, thereby releasing the fixed relationship between the mounting seat and the mounting axis 4, and then the angle can be adjusted around the mounting axis 4;

[0061] As the Dendrobium plant grows, the illumination angle of the LED lamp also needs to be adjusted. The adjustment device 1 and the adjustment device 2 can synchronously adjust the illumination angles of all LED lamps 2, which is more convenient than workers adjusting the illumination angles one by one, and reduces the workload of workers. There are some Dendrobium plants whose height or straightness is different from other plants due to varieties and other reasons. Therefore, after the overall LED lamp is synchronously adjusted, the angle of the LED lamp illuminating this plant needs to be adjusted separately. The present invention is provided with a mounting seat, and the structure thereon can realize manual adjustment of the illumination angle, thereby solving this demand.

[0062] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit and essential features of the invention.
