LED LAMPS FOR IRRADIATION OF GLASSHOUSE PLANTS
Description
At present, much attention is paid to the production of domestic vegetable products. One of the main reserves of increasing the yield of vegetables is the production of products in sheltered ground. The intensive construction of new glasshouses and greenhouses complexes has sharply increased the demand for engineering facilities, with the help of which an artificial microclimate is created in the structures of the protected soil. To create high irradiations, a very significant specific installed power of photosynthetic radiation sources is required. Currently, advanced greenhouse plants use LED irradiation. The experience of these farms showed that LED irradiators have a number of significant advantages over discharge lamps: a significantly lower specific power of the irradiator; the service life of LEDs is several times higher; they do not contain toxic substances (mercury); LEDs are powered from a low voltage network, which is significant from a safety standpoint. Isolation of greenhouse plants from the effects of natural factors of the environment leads to undesirable consequences. The deficit of the amount of natural energy of optical radiation penetrating the structures of protected ground in modern industrial greenhouses during off-season is eliminated by additional artificial radiation from greenhouse lamps. In this case, the emission spectrum of lamps differs significantly from the natural one. This is especially true for ultraviolet radiation. The issue of creating an LED lamp for its application in structures of protected ground is considered. The main requirements for the creation of a photosynthetic lamp on the spectral composition of radiation are given. The necessity of a long-wave ultraviolet component in the emission spectrum of a lamp is substantiated
