Conception and design of a lighting system based on Light Emitting Diodes for spectrum simulation

This work aims to develop an electronic system based on Light Emitting Diodes (LEDs) to emulate a reference light spectrum. Light Emitting Diodes are used due to their well-known advantages over other light sources. As an example of application, this work focuses on the design and implementation of a solid-state solar simulator whose spectrum resembles the natural daylight to support research on photosynthetic organisms. The system design and a spectrum optimization process are presented. Mixed Integer Programming (MIP) is adopted to set the optimal amount of LEDs that result in the most accurate response. The study of the LED spectrum, power converters for LED driving and control are discussed.
