Greenhouse system
First Claim
1. Greenhouse system for providing illumination to plants in a greenhouse for the benefit of plant growth, the system comprisinga lamp or lamps for the illumination of the plants inside the greenhouse;
- a sensor or sensors for measuring wavelength distribution of actual light in the greenhouse; and
a controller coupled to the lamp or lamps and the sensor or sensors and configured to control the lamp or lamps in dependency of the output of the sensor or sensors by varying intensity and spectral distribution of the light emitted by the lamp or lamps in dependency of the output of the sensor or sensors for measuring the wavelength distribution.

Abstract
Greenhouse system may comprise an illumination, a sensor, and a controller. The illumination and controller are arranged to vary the intensity and the spectral distribution of the light emitted by the illumination. The emitted light may be pulsed light, the pulse characteristics being variable by the controller in dependency of the output of the sensor. The controller is arranged to interpret the relevant variables measured by the sensor and to assess the actual and/or expected growth of the relevant plants, and to control the intensity and/or the spectral distribution of the light emitted by the illumination. Some sensors may be provided for measuring the intensity and/or spectral distribution of the actual light in the greenhouse, other sensors for measuring plant dimensions of the relevant plants or plant groups. The illumination may comprise a heat collector which can be connected to heating or air conditioning inside or outside the greenhouse.

5. A tangible, non-transitory, computer-readable medium comprising a computer program with instructions that, when executed by a programmable computer, will cause the computer to interpret at least one of CO2 pressure, temperature, air humidity and soil humidity measured by a sensor or sensors in a greenhouse and to assess the actual and/or expected growth of plants, and to generate a control signal for controlling the intensity and/or the spectral distribution of light emitted by a lamp or lamps, to those plants in accordance with a result of the assessment.
