Abstract
This work presents an electronic system in order to provide a simplified and efficient alternative for plants physiology experiment as well as for its utilization in greenhouses. Initially, it is shown a brief description regarding the artificial lighting and plants cultivation interaction, aiming the interpretation about plants behavior in botanic studies and to help the oriented and commercial crops purposes. Based on some previous work, it is proposed an autonomous system comprised of a white LEDs lighting fixture. Moreover, this paper includes an experimental prototype in order to evaluate converter efficiency and radiometric lamp behavior. Thus, the results have shown that the developed system is able to integrate flexibility, accurate control and relevant radiometric for some selected crops.
