A Supplementary Lighting System for Plant Growth with Lighting-Emitting Diode Based on DT TS&IC

Abstract

In order to achieve quantitative supplementary lighting at different stages of plant growth, design a lighting system with LED that can provide different light quality. The system monitor illumination of light quality with specific wavelength in real-time, ambient temperature, the amount of light that plant really need, and control the brightness of red, blue LED lights by pulse width modulation (PWM) signal. The system can be used for different plants at different growth stages under different environments with different demand in light quantity and quality , with accurate, intelligent, low-power features. The system prevents plants from suffering light deficiency or excess, improve energy efficiency.
