LED Dynamic Lighting Control System for Greenhouses
The SSHLighting (solid-state horticultural lighting system) project was a recent collaboration between researchers from Aalto University and the University of Helsinki. One of the project's goals was to develop and test a dynamic lighting control (DLC) scheme for plant growth applications in greenhouses using warm-light LEDs. The LED-DLC lighting system was used for instantaneous compensation of lack in daylight availability, and aimed to reduce electrical consumption as well as improve plant growth. This video shows a time-lapse of lettuce plants growing under the LED-DLC lighting system in a greenhouse environment. The use of the DLC resulted in a 20% reduction in the electricity consumption in comparison to a similar lighting system operated under a discontinuous on?off regime.
