Abstract

The paper presents the LED illumination control system that is applied in plant tissue culture. Monochromatic light illuminating with appropriate light intensity will produce high bio-energy efficiency that in turn stimulates the growth of the plant than other types of conventional bulb. This article presents a light controller system for LED arrays with power of 24W (24 bulbs 1W) which features: controlling the light intensity of LED arrays, displaying real time; being able to set up process of cultivation, saving and exporting data for research report.
