Solid-state lighting (SSL) refers to the technology used in light-emitting diodes (LEDs) and organic light-emitting diodes (OLEDs) to produce light. Unlike traditional incandescent bulbs or fluorescent lights, which rely on heating a filament or exciting a gas to generate light, solid-state lighting uses semiconductors to convert electrical energy directly into light.
LEDs, the most common form of solid-state lighting, are tiny semiconductor devices that emit light when an electric current passes through them. They are made of a semiconductor material, typically a compound of gallium, indium, and nitrogen (GaN), which produces visible light when electrons recombine with electron holes. The color of the emitted light depends on the specific materials used and the energy bandgap of the semiconductor.
Solid-state lighting offers several advantages over traditional lighting technologies. Here are a few key benefits:
Solid-state lighting has revolutionized the lighting industry and is widely used in various applications, including residential lighting, street lighting, automotive lighting, display screens, and backlighting for televisions, computers, and mobile devices. The technology continues to advance, offering even greater efficiency, improved color rendering, and new applications in areas such as horticultural lighting and smart lighting systems.
Thermal materials play a crucial role in lighting applications, particularly in managing heat generated by the light source. Excessive heat can degrade the performance and lifespan of lighting components, so effective thermal management is essential to ensure optimal operation and reliability. Here are some important thermal materials used in lighting:
