Domestic Horticultural – Centric Lighting Design

Lighting and particularly coloured lighting is a vital factor that contributes to plant growth inducing both photosynthesis, phototropism and photo-morphogenesis. Detailed experimental studies on the photobiology of plants have already shown the importance of creating lighting receipts specific for different species’ growth and development in order to obtain a good plant productivity and nutritional quality formation. LEDs, nowadays, represent a good solution for creating the proper lighting receipts composed by different narrow wavelength specifically combined for every plant. Small dimensions, long operating lifetime, great efficiency, digitally controllable features and optically controllable performances are also useful aspects for an horticultural – centric lighting not only for laboratorial research experimentations, for aero-spatial and industrial food production but also for educational, medicinal and therapeutic scopes [1-2-3]. More than this, domestic food farming is currently an increasing trend derived by both the emergent interest in eating healthy, genuine, km-0 and origin controlled food combined with a raising necessity of nature reconciliation through sustainable behaviours and responsible choices [4]. In this regard, an LEDs lighting system for home farming can be a possible solution especially in domestic environment lacking natural lighting or good climatic conditions, with limited or absent natural spaces as gardens, terraces and balconies.
