Description

Technical Field

[0001] The present application relates to the field of plant cultivation, and in particular to a reflective device for plant growth. Background Art

[0002] Lighting is essential for plant growth. During plant cultivation, when natural light sources are unable to provide sufficient illumination for plants, artificial supplemental lighting devices are needed to supplement the light supply to promote plant growth. However, different plants require different supplemental lighting durations, and excessive supplemental lighting can negatively impact plant growth. When supplemental lighting is required for a variety of plants distributed over a large area, using a single light source consumes a lot of energy. Furthermore, since different plants require different supplemental lighting durations, a single light source cannot meet the illumination duration requirements of each plant. Using multiple light sources for one-on-one illumination of plants is cumbersome, requiring more space and hindering operators from performing other plant cultivation operations.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] like Figure 1 As shown, this embodiment provides a reflective device for plant growth, including a base plate 1, an LED light bar 2, and a reflector 3.

[0021] Specifically, such as Figure 1 As shown, the bottom plate 1 is in the shape of a rectangular plate and is used to carry plants to be cultivated.

[0022] Specifically, such as Figure 1 As shown, the LED light strip 2 is arranged above the base plate 1, and its length direction is parallel to the width direction of the base plate 1. The light emitting surface of the LED light strip 2 is the upper surface, and its light emitting direction is parallel to the height direction of the base plate 1.

[0023] Specifically, such as Figure 1 As shown, there are two reflectors 3, the front of the reflector 3 is used to reflect light, the reflectors 3 are all arranged above the LED light strip 2, and their length directions are parallel to the width direction of the base plate 1, and the reflectors 3 are respectively rotated around two rotation axes parallel to the width direction of the base plate 1, and the rotation axes are respectively located on the symmetrical planes of the two side surfaces of the corresponding reflectors 3, which means that the rotation axes and the back surfaces of the corresponding reflectors 3 are separated by the same predetermined distance, and the reflectors 3 corresponding to the above-mentioned rotation axes are reflectors that rotate around the rotation axes; the spacing between the rotation axes and the base plate 1 is equal and they are both movable along the length direction of the base plate 1, and the reflectors 3 are movable following the corresponding rotation axes.

The first reflector 3 is moved to the top of the LED light strip 2, and the first reflector 3 is rotated so that the front of the first reflector 3 faces the side of the base plate 1 and forms an angle of forty-five degrees with the upper surface of the base plate 1. The second reflector 3 is rotated so that the front of the second reflector 3 faces the base plate 1 and is perpendicular to the front of the first reflector 3. At this time, the light beam emitted by the LED light strip 2 will be reflected by the first reflector 3 to the second reflector 3, and then reflected by the second reflector 3 to the plant directly below the second reflector 3. The second reflector 3 is moved so that the second reflector 3 irradiates the plant directly below it in different time periods. When light needs to be irradiated to the plant at different angles, the second reflector 3 is moved and rotated to achieve light irradiation to the plant at different angles.

[0025] When irradiating the plants on the other side of the LED light strip 2, move the second reflector 3 to the top of the LED light strip 2, rotate the second reflector 3 so that its front faces the other side of the base plate 1 and forms a forty-five degree angle with the upper surface of the base plate 1.

[0028] Preferably, Figure 1 As shown, divergent lenses 4 are further provided on both sides of the LED light strip 2. The length directions of the divergent lenses 4 are parallel to the width direction of the base plate 1. The divergent lenses 4 are all arranged to move along the height direction of the base plate 1.

The front faces of the divergent lenses 4 are respectively arranged toward both sides of the LED light strip 2. The divergent lenses 4 are used to scatter the light received on its back side from its front side.

[0029] During operation, when it is necessary to illuminate all the plants on one side of the LED light bar 2, raise the divergent lens 4 on one side of the LED light bar 2, move one of the reflectors 3 to directly above the LED light bar 2, and rotate one of the reflectors 3 so that one of the reflectors 3 reflects the light beam emitted by the LED light bar 2 to the back side of the divergent lens 4 on one side of the LED light bar 2. After the light beam is diverged by the divergent lens 4, it illuminates all the plants on one side of the LED light bar 2.
