Illumination device for targeted and controlled illumination e.g. of plants in greenhouse, uses laser light at specific wavelengths to illuminate specific site or surface

摘要

Laser light at a wavelength of 435 nm and 660 nm is used to illuminate specific sites and surfaces of all kinds. A cardan-type arranged laser (1) moves to create loop-shaped, diagonal, or point-wise beams of light over the surface automatically using a computer, to give constantly the optimally required quantity of light to the surface or the plants.
