Abstract
The performance of LED-based light sources is increasing day- by-day, thanks to the continuous efforts of manufacturers and researchers on the developments of this technology. As a consequence, solid-state light sources have higher efficiency and similar color rendering compared to conventional light sources, and have costs that are rapidly decreasing as the market penetration increases. Despite the excellent characteristics of modern power LEDs, several factors complicate the development of robust and efficient LED-based light sources, including a non-trivial thermal management, problems related to chemical compatibility, the need of designing suitable optical and mechanical design, and developing efficient electrical configurations
