LEDs have come a long way since the early days of lighting up digital clock faces. Remarkable progress has been made in the efficacy and color quality of LEDs in the last few years. Understanding LED Illumination presents light propagation and distribution characteristics of LED light sources for general illumination applications. The author provides an introduction to lighting fundamentals and technologies, and then LED science and technologies. Lamp designs, lighting theory, simulations and efficiency limiting factors are discussed as well. The author also addresses LED replacement lamps for household and commercial lighting use, as well as design for improving tubular LED replacement. The book includes an extensive reference list and index. Judging by the title of the book, I expected that it had been written for general public. However, this text is actually designed to teach scientists and engineers the fundamentals of lighting and LED lamp design.
