  • Patent number: 8232731
    Abstract: The invention relates to a method, a control system and a shed wherein the lighting is adjusted depending on the presence of an animal in a specific section of a shed. The shed is divided into a number of sections, for example a separation section. When no cows have access to the separation section and the section is therefore empty, the control system ensures that the lighting in the respective section is switched off. As the control system according to the invention controls both access to the section and lighting thereof, it is possible to dispense with movement sensors for controlling lighting in the respective sections.
