Abstract
Aiming at meeting the need of plant characteristic spectrum research, a lighting system is designed which chooses STC89C52RC as the control core, uses RX5801 chip to drive multi channel high-power LED with constant current and takes PWM to adjust the intensity. The system achieves the goal of multi-channel LED working independently, multi-stage adjustable intensity as well as any combination of different spectra with different intensity. Its abundant spectral combination can provide the experimental conditions for the study of different plant characteristic spectrum effect on plant growth.关键词
