Abstract :
The plants growth included photosynthesis, photo morphogenesis, photoperiod adjusting and light intensity selectivity with spectrum. Multi-LED lighting for strawberry mainly confirms the main spectrum to match emission spectrum with the selective absorption spectrum of plants; Matching a variety of appropriate wavelength LED; The present system simulated sunlight from the visible light range to the infrared light. The LED light intensity all be regulate arbitrary in the range and simulate spectral distribution of the sunlight on time by pulse width modulation(PWM). A phalanx with 9 lines and 9 rows was adopted.
