Claim Text:
1. An irradiation device for irradiating plants, the device comprising a carrier element defining a culture plane for cultivating the plants, multiple radiation sources for irradiating the plants with at least one of visible and ultraviolet irradiation, and multiple infrared emitters for irradiating the plants with infrared radiation, the infrared emitters being designed for a temperature from 800° C. to 1800° C. and each of the infrared emitters having a cylindrical emitter tube having an emitter tube length in a range from 50 mm to 500 mm and a reflector facing an installation space B allocated to a top side of the emitter tube, wherein the emitter tubes extend parallel to each other in an emitter zone Z lying above the culture plane, wherein a population density of the infrared emitters in relation to a surface area of the culture plane is in a range between 0.2 m −2 and 1.0 m −2 , and wherein irradiation areas of adjacent ones of the infrared emitters overlap on the culture plane, such that an average irradiation intensity on the culture plane is between 10 W/m 2 and 100 W/m 2 with a maximum fluctuation range of 50%.
