LED lamp with spectral characteristics suitable for application in greenhouses

The aim of this work is investigating the possibilities for creation of energy effective LED modules with special spectral characteristics and radiant flux, suitable for greenhouse applications. Combinations of different types of LEDs and LED modules are tested to achieve spectral power distribution proper for particular types of plants. Proper thermal management analysis and experimental investigations in thermal chamber are made. Safety operation conditions for LEDs are determined in dependence of LEDs' operation regimes and ambient conditions.
