Solid-state lighting (SSL) refers to a type of lighting that uses semiconductor devices, such as light-emitting diodes (LEDs), to produce light. Unlike traditional lighting methods, which rely on filaments or gas, SSL technology is more energy-efficient and has a longer lifespan. This makes it a popular choice for both residential and commercial applications. One of the key advantages of solid-state lighting is its ability to emit light in a specific direction, reducing the need for reflectors and diffusers. Additionally, SSL can be easily integrated with smart technology, allowing for features like dimming and color changing, enhancing its versatility in various settings.
