Solid State Lighting (SSL) refers to a type of lighting that uses semiconductor light-emitting diodes (LEDs), organic LEDs (OLEDs), or polymer LEDs (PLEDs) as sources of illumination, offering high energy efficiency, long lifespan, and reduced environmental impact compared to traditional lighting technologies. SSL is revolutionizing the lighting industry by enabling advanced features such as color tuning, smart lighting controls, and integration with digital networks.
