Abstract

A light for growing plants includes at least one light source for generating light for growing at least one plant to be grown, at least one detection device for detecting at least one state parameter of the plant, and at least one adjustment device for moving the at least one light source relative to the plant depending on the at least one state parameter.

First claim

The invention claimed is:

1 . A light for growing plants, the light comprising:
a light base body, at least one light source for generating light for growing at least one plant to be grown, at least one detection device for detecting at least one state parameter of the at least one plant to be grown, and at least one adjustment device for moving the at least one light source relative to the at least one plant to be grown depending on the at least one state parameter detected by the at least one detection device, wherein the at least one adjustment device includes at least one boom pivotably mounted in relation to the light base body, wherein the at least one light source is arranged to be moved in relation to the light base body upon pivoting the at least one boom and to be movable along the at least one boom, and wherein the at least one adjustment device includes a linear drive, wherein the at least one boom is coupled via a coupling element to the linear drive of the at least one adjustment device, and wherein the at least one light source is coupled to the linear drive of the at least one adjustment device so that the movement of the at least one light source along the at least one boom depends on the pivot position of the at least one boom.

2 . The light as claimed in claim 1 , wherein the at least one light source is arranged on at least one flexible substrate.

3 . The light as claimed in claim 2 , wherein the at least one flexible substrate is movable along at least one boom of the at least one adjustment device.

4 . The light as claimed in claim 2 , wherein the at least one flexible substrate is coupled to a linear drive of the at least one adjustment device.

5 . The light as claimed in claim 1 , further comprising at least two light sources, wherein the at least two light sources are arranged such that light is irradiable from at least two sides onto the at least one plant to be grown by means of the at least two light sources.

6 . The light as claimed in claim 1 , wherein the at least one detection device includes at least one of at least one spectrometer, at least one distance sensor and at least one 3D scanner.

7 . The light as claimed in claim 1 , further comprising at least one secondary detection device for detecting at least one further state parameter of the at least one plant to be grown.

8 . An apparatus for growing plants, the apparatus comprising:
at least one light as claimed in claim 1 and at least one vessel for accommodating at least one plant substrate.

9 . The apparatus as claimed in claim 8 , further comprising at least one of at least one liquid reservoir and at least one fertilizer reservoir for supplying the at least one plant to be grown with at least one of liquid and fertilizer depending on at least one detected state parameter of the at least one plant to be grown.

10 . The light as claimed in claim 1 , wherein the at least one light source is arranged along a flexible substrate in the form of a light band that is configured to be guided by a linear guide on the at least one boom to provide relative linear movement of the light band in relation to the boom.

11 . The light as claimed in claim 1 , wherein the light base body includes a stand arranged in a central location of the light, and
wherein the stand extends in a vertical direction with the at least one boom being pivotally mounted to extend out from the light base body.

12 . A method for growing plants, the method comprising:
providing at least one plant to be grown, providing a light as claimed in claim 1 , irradiating light onto the at least one plant to be grown by means of the at least one light source, detecting at least one state parameter of the at least one plant to be grown by means of the at least one detection device, and moving the at least one light source relative to the at least one plant to be grown depending on the at least one state parameter by means of the at least one adjustment device.

13 . The method as claimed in claim 12 , wherein at least one of a leaf area index and a size of the at least one plant is detected by means of the at least one detection device.

14 . The method as claimed in claim 12 , wherein an emission characteristic of the at least one light source is varied depending on the at least one state parameter detected.

15 . The method as claimed in claim 12 , wherein at least one additional state parameter of the at least one plant to be grown is ascertained.

16 . The method as claimed in claim 15 , wherein at least one of the water content and the nutrient content of the at least one plant is ascertained.

17 . The method as claimed in claim 12 , further comprising a calibration step for determining a starting configuration of the light at the beginning of growing the plants.

18 . The method as claimed in claim 12 , wherein the movement of the at least one light source takes place in at least two degrees of freedom.

19 . The method as claimed in claim 18 , wherein the movement in different degrees of freedom takes place in a coupled manner.

20 . The method as claimed in claim 12 , further comprising a calibration step for determining at least one of a position and an emission characteristic of the at least one light source at the beginning of growing the plants.
