Luminárias led para uso em cultivos de plantas com enfoque em controle do período de floração

Abstract

With the appreciation and expansion of the Brazilian floriculture market, the need to produce flowers throughout the year becomes inevitable. This is due to the great demand for this type of product in an ornamental, fresh and regular way, in addition to the fact that demand peaks on special dates. Therefore, being able to carry out the production and control of flowers production becomes attractive for the entire production chain. Thus, studies aiming at the use of LED modules with specific spectra for these purposes are essential for market development. So, the purpose of this work is to carry out a methodology for characterizing technical parameters regarding the components to be used in LED modules to control the period destined to flowering for sunflower (Helianthus annuus L.) cultures Vicent's choice and a statice (Limonium sinuatum) purple. Thermal, electrical and lighting issues are also addressed, both theoretically and in practice. Finally, the behavior of the flow of photons emitted by the different LED modules suggested during the work is analyzed.
