Growth chamber illumination with a special luminaire

Article describes the design of lighting in growth chamber with low energy consumption. For this purpose we created a special luminaire that allows during different phases of plant life, regulate the spectrum of emitted energy and thereby effectively utilize light without wasting electricity. It is also important light intensity for proper growth of plants, respectively incident radiation. The paper discusses the directional characteristics of the luminaire and its spectral distribution which are an important part of the input data for the design lighting.
