The Potential Savings in Power Consumption of Greenhouse Lighting Caused by the Transition from High-Pressure Sodium Lamps to White LED

Popis výsledku v původním jazyce

This study delves into the substantial energy savings achievable in large greenhouses through the adoption of white LED lighting, moving away from traditional high-pressure sodium lamps. Given the escalating importance of sustainable agricultural practices, the necessity of optimizing greenhouse lighting for enhanced plant growth while simultaneously reducing power consumption is necessary. This paper analyzes LED light sources by the conversion of light technical parameters into radiant and photosynthetic values that plants require. This process is crucial for determining the benefit of LED lights for the specific photosynthetic photon flux (PPF) demands of plants. The procedure introduced in this paper describes the relationship between luminous flux and PPF to facilitate the design of energy-efficient lighting systems for large-scale greenhouses. Utilizing standard lighting design software, the study proposes a light-technical model that specifies the photosynthetic photon flux density (PPFD) across different distances within the greenhouse, alongside data on power consumption. The energy efficiency of the proposed lighting system is thoroughly evaluated, considering the LEDs’ efficacy in converting electrical power to usable plant light and the overall efficiency of the lighting fixtures. © 2025 Elsevier B.V., All rights reserved.
