Abstract

Solid state lighting has brought about a revolution in the lighting industry due to its superior performance, energy efficiency and long lifespan in comparison to traditional incandescent and fluorescent lighting technologies. This comprehensive review article aims to provide an overview of recent advancements in SSL technologies as well as their applications. Firstly. We discuss the fundamental principles and materials involved in solid state lighting before providing a detailed examination of the key developments in SSL devices such as Light Emitting Diodes (LEDs) and Organic Light Emitting Diodes (OLEDs). The article also looks into SSL research including novel fabrication techniques, enhanced efficiency, and color rendering properties. Additionally. There is an exploration of how solid-state lighting is applied across general lighting, automotive lighting, and horticultural lighting sectors. In conclusion, this review consolidates future prospects and challenges regarding solid state lighting.
