[0001] The utility model relates to the technical field of plant supplementary lighting lamps, in particular to an LED plant supplementary lighting lamp for greenhouse cultivation. Background Art

[0002] Greenhouse cultivation is a cultivation method for horticultural crops. It uses heat preservation, heating, light transmission and other equipment (such as cold beds, hot beds, greenhouses, etc.) and corresponding technical measures to protect thermophilic plants from cold and winter or promote growth and early flowering and fruiting. In order to further promote plant growth, it is necessary to irradiate the plants with LED plant fill lights at night so that the plants can photosynthesize at night.

[0003] The existing LED plant fill light has the highest brightness in the direction of illumination when the lamp is in use, and the light diffuses around with the illumination direction as the center. As the diffusion brightness gradually decreases, the growth of plants varies when the plant fill light is used. The existing LED plant fill light has a fixed illumination direction, and the illumination position of the LED plant fill light cannot be adjusted. As a result, when the plants need to be picked later, some mature prematurely and some need to continue growing, which is inconvenient to use. Utility Model Content

[0004] The purpose of the utility model is to provide an LED plant fill light for greenhouse cultivation, which can adjust the irradiation direction of the fill light at will, thereby facilitating the irradiation of vegetable areas with poor growth, making the growth of vegetables in the greenhouse more uniform and facilitating the later picking.

[0011] Preferably, the tooth pitch of the locking teeth is equal to the tooth pitch of the gear, and the locking teeth are elastically connected to the hanger via a spring.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. In the utility model, the fill light and the worm wheel form a lateral rotation, and the worm wheel forms an axial rotation with the hanger through the rotating shaft.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example:

[0022] See also Figures 1 to 3 The utility model provides a technical solution: an LED plant fill light for greenhouse cultivation, comprising a hanger 1, a rotating shaft 2 is rotatably connected to the middle of the hanger 1, and a gear 3 is fixedly connected to the bottom end of the rotating shaft 2, wherein:

[0023] The bottom of the gear 3 is fixedly connected with a worm wheel 4, and a fill light 5 is arranged below the worm wheel 4, and the fill light 5 is rotatably connected with the worm wheel 4;

[0025] The fill light 5 and the worm wheel 4 form a lateral rotation, and the worm wheel 4 forms an axial rotation with the hanger 1 through the rotating shaft 2. When it is necessary to adjust the irradiation direction of the fill light 5, the worm 6 is rotated. Through the engagement of the worm 6 and the worm wheel 4, the worm 6 drives the fill light 5 to rotate lateral while rotating to adjust the angle of the fill light 5. Then, the fill light 5 is rotated axially through the rotating shaft 2. Through this adjustment structure, the irradiation direction of the fill light 5 can be adjusted at will, thereby facilitating the irradiation of vegetable areas with poor growth, making the growth of vegetables in the greenhouse more uniform and facilitating later picking.

The photovoltaic power generation mechanism includes a photovoltaic power generation panel 7. The photovoltaic power generation panel 7 is installed on the top of the hanger 1. A battery 8 is installed on the top of the hanger 1 corresponding to the photovoltaic power generation panel 7. The battery 8 is electrically connected to the fill light 5. During the day, the photovoltaic power generation panel 7 converts solar energy into electrical energy, and the electrical energy is stored in the battery 8. When fill light is needed at night, the battery 8 is used to power the fill light 5, which can effectively save energy.

[0027] See also Figures 1 to 3 The locking mechanism includes a sliding frame 9, a sliding frame 9 is arranged on the bottom of the hanger 1 near the gear 3 for horizontal sliding, a locking tooth 10 is fixedly connected to the sliding frame 9 at an equidistant distance on one side of the gear 3, a sliding groove 11 is provided at the bottom of the hanger 1 corresponding to the sliding frame 9, a sliding block 12 is fixedly connected to the top of the sliding frame 9 corresponding to the sliding groove 11, a spring 13 is installed between the side of the sliding block 12 away from the locking tooth 10 and the inner end of the sliding groove 11, the tooth pitch of the locking tooth 10 is equal to the tooth pitch of the gear 3, and the locking tooth 10 is elastically connected to the hanger 1 through the spring 13. When the fill light 5 needs to be axially rotated through the rotating shaft 2, the sliding frame 9 drives the locking tooth 10 to overcome the elastic force of the spring 13 and move away from the gear 3, so that the rotating shaft 2 can rotate. After the adjustment is completed, the sliding frame 9 is released, and the locking tooth 10 is driven by the spring 13 to move toward the gear 3, so that the gear 3 is meshed with the locking tooth 10, thereby fixing the rotating shaft 2 to prevent the fill light 5 from rotating itself when in use.

[0028] Working principle: In this LED plant fill light for greenhouse cultivation, the fill light 5 and the worm wheel 4 form a lateral rotation, and the worm wheel 4 forms an axial rotation with the hanger 1 through the rotating shaft 2. When it is necessary to adjust the irradiation direction of the fill light 5, the worm 6 is rotated, and the worm 6 is meshed with the worm wheel 4, so that the worm 6 drives the fill light 5 to rotate horizontally while rotating, and the angle of the fill light 5 is adjusted. Then, the fill light 5 is rotated axially through the rotating shaft 2. Through this adjustment structure, the irradiation direction of the fill light 5 can be adjusted at will, so as to facilitate the irradiation of the vegetable area with poor growth, so that the growth of vegetables in the greenhouse is more uniform, which is convenient for later cultivation. The picking is carried out, and during the day, the photovoltaic panel 7 converts solar energy into electrical energy, and the electrical energy is stored in the battery 8. When supplementary lighting is needed at night, the battery 8 is used to power the supplementary light 5, which can effectively save energy. When the supplementary light 5 needs to rotate axially through the rotating shaft 2, the sliding frame 9 drives the locking tooth 10 to overcome the elastic force of the spring 13 and move away from the gear 3, so that the rotating shaft 2 can rotate. After the adjustment is completed, the sliding frame 9 is released, and the locking tooth 10 is driven by the spring 13 to move toward the gear 3, so that the gear 3 is meshed with the locking tooth 10, thereby fixing the rotating shaft 2 to prevent the supplementary light 5 from rotating itself during use.
