Fundamentals and Applications of Light-Emitting Diodes : The Revolution in the Lighting Industry

Traditional light sources are fast being replaced by light-emitting diodes (LEDs). The fourth generation of lighting is completely dominated by LED luminaires. Apart from lighting, LEDs have extended its hold on other fields such as digital communications, horticulture, medical fields, space research, art and culture, display devices, entertainment, etc. The technological promises offered by LEDs have elevated it as a front-runner in the lighting industry. This book will explore the journey of LEDs for readers belonging to scientific community.

This book reviews the general understanding of the luminescence process and the background of solid state lighting. It includes special emphasis on the phosphor-converted LEDs that are based on inorganic phosphors. It also explores the different types of LEDs that are based on inorganic, organic, quantum dots, perovskite-structured materials and biomaterials. A detailed description has been included about the diverse applications of LEDs in fields such as lighting, displays, horticulture, biomedical and digital communication. Considerable importance has been given to discussion of the challenges that must be solved before using LEDs in commercial applications.
