[0002] Light environment is one of the essential physical environmental factors for plant growth and development. Controlling plant morphology through light quality regulation is an important technology in the field of facility cultivation. Plant lighting is even more environmentally friendly and energy-saving. Plant lighting provides plants with photosynthesis, promotes plant growth, supplements light for plants or completely replaces sunlight. Plant lights are very suitable for plant growth, flowering and fruiting, shortening the time for plants to flower and fruit, and improving production. In modern construction, it is an indispensable product for crops.

[0003] In existing technologies, the illumination range of lighting lamps is not adjustable. When there are many plants or the required light intensity is high, the limited illumination range of the lighting lamps cannot meet the growth needs of the plants, resulting in slow plant growth. Furthermore, the light from existing lighting lamps has a wide dispersion range, which cannot concentrate the light on the plants, affecting the photosynthetic efficiency of the plants and causing a large loss of light and electrical energy. Utility Model Content

[0004] The purpose of this invention is to provide a plant lighting lamp with adjustable illumination range to solve the problems mentioned in the background art.

Detailed Implementation

[0021] 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.

[0022] This utility model provides a technical solution: such as Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, in this embodiment, a plant lighting lamp with adjustable illumination range includes a mounting base 1, a fixing base 9 fixedly mounted on the mounting base 1, a base 10 fixedly mounted below the fixing base 9, a reflector 8 provided below the mounting base 1, three sets of annularly distributed guide rails 11 fixedly mounted inside the base 10, three sets of annularly distributed guide rods 12 provided between the base 10 and the fixing base 9, the three sets of guide rods 12 corresponding to the guide rails 11, the guide rods 12 and the guide rails 11 being slidably connected, and an adjustment rod 13 fixedly mounted on each of the three sets of guide rods 12, a disc 14 provided inside the fixing base 9, and multiple sets of annularly distributed adjustment rods provided on the disc 14. The groove 15 has multiple sets of adjustment grooves 15 corresponding to the adjustment rod 13. The adjustment rod 13 is slidably connected to the disc 14 through the adjustment groove 15. Below the three sets of guide rods 12, there are multiple sets of equidistantly distributed adjustment blocks 21. Each set of adjustment blocks 21 has a lamp holder 22 fixedly installed below it. When the motor in the fixed seat 9 drives the screw 19 to rotate, the rack 18 slides under the limiting action of the fixed seat 9. The second gear 17, which meshes with the rack 18, drives the rotating rod 16 and the disc 14 to rotate. The annularly distributed adjustment grooves 15 on the disc 14 rotate accordingly, thereby causing the adjustment rod 13, which is slidably connected to the disc 14 through the adjustment groove 15, to be limited by the guide rail 11. Under the action of the position, the corresponding guide rod 12 slides in the guide rail 11, completing the synchronous adjustment of the positions of the three sets of guide rods 12. The disc 14 is rotatably connected to the fixed seat 9 through the rotating rod 16. The rotating rod 16 is sleeved with the second gear 17. The fixed seat 9 is slidably installed with a rack 18, which meshes with the second gear 17. The fixed seat 9 is provided with a screw 19, the two ends of which pass through the fixed seat 9 and are rotatably connected to the fixed seat 9 through bearings. The screw 19 passes through the rack 18 and is threadedly connected to the rack 18. Limit rails 20 are fixedly installed on all three sets of guide rods 12. The two sets of adjusting blocks 21 on both sides are respectively connected to the guide rods 12 and the guide rails 12. The base 10 is fixedly connected, and the limiting rail 20 is slidably connected to multiple sets of adjusting blocks 21. Each set of adjusting blocks 21 is rotatably mounted with two sets of cross-distributed connecting rods 23. The connecting rods 23 between adjacent sets of adjusting blocks 21 are rotatably connected by a rotating shaft. During the sliding of the guide rod 12, the limiting rail 20 and the adjusting blocks 21 fixedly connected to it slide synchronously. During the sliding of the outermost adjusting block 21, the cross-distributed connecting rods 23 between adjacent adjusting blocks 21 move accordingly, causing the multiple sets of adjusting blocks 21 to move at equal distances, thereby realizing the adjustment of the spacing and illumination range between multiple sets of lamp holders 22 below the base 10.

[0023] like Figure 1 and Figure 2As shown, the mounting base 1 has a mounting ring 2 inside, which is rotatably connected to the mounting base 1 via a bearing. A toothed ring 3 is sleeved on the mounting ring 2. Multiple sets of annularly distributed adjustment frames 4 are provided below the mounting base 1. Each set of adjustment frames 4 has a bracket 7 fixedly mounted on it. The reflector 8 is fixedly sleeved on the multiple sets of annularly distributed brackets 7. The multiple sets of adjustment frames 4 are rotatably connected to the mounting base 1 via mounting shafts 5. Each set of mounting shafts 5 has a first gear 6 sleeved on it. The multiple sets of first gears 6 are meshed with the toothed ring 3. When the motor inside the mounting base 1 drives one set of mounting shafts 5 to rotate, the first gear 6 on the mounting shaft 5 rotates accordingly, thereby driving the toothed ring 3 to drive the mounting ring 2 to rotate. When the mounting ring 2 rotates, the multiple sets of first gears 6 drive the mounting shafts 5 to rotate synchronously, and the multiple sets of adjustment frames 4 rotate synchronously, changing the diameter of the circle formed by the multiple sets of brackets 7, thereby adjusting the radius of the reflector 8. The reflector 8 is made of an elastic and stretchable material.

[0024] This utility model provides a plant lighting lamp with adjustable illumination range. The specific working principle is as follows: When the motor inside the fixed base 9 drives the screw 19 to rotate, the rack 18 slides under the limiting action of the fixed base 9. The second gear 17, meshing with the rack 18, drives the rotating rod 16 and the disc 14 to rotate. The annularly distributed adjustment grooves 15 on the disc 14 rotate accordingly. This causes the adjustment rod 13, which is slidably connected to the disc 14 via the adjustment grooves 15, to drive the corresponding guide rod 12 to slide within the guide rail 11 under the limiting action of the guide rail 11, thus completing the synchronous adjustment of the positions of the three sets of guide rods 12. During the sliding process of the guide rod 12, the limiting rail 20 and the adjustment block 21 fixedly connected to it also slide together. As the outermost adjusting block 21 slides, the connecting rods 23 that are intersected between adjacent adjusting blocks 21 move accordingly, causing multiple sets of adjusting blocks 21 to move at equal intervals, thereby adjusting the spacing between multiple sets of lamp holders 22 below the base 10 and the illumination range. When the motor inside the mounting base 1 drives a set of mounting shafts 5 to rotate, the first gear 6 on the mounting shaft 5 rotates accordingly, thereby driving the gear ring 3 to drive the mounting ring 2 to rotate. When the mounting ring 2 rotates, multiple sets of first gears 6 drive the mounting shafts 5 to rotate synchronously, and multiple sets of adjusting brackets 4 rotate synchronously, changing the diameter of the circle formed by multiple sets of brackets 7, thereby adjusting the radius of the reflector 8, wherein the reflector 8 is made of an elastic and stretchable material.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
