Incandescent luminescence refers to the visible light produced when atoms are excited by heat. This process is used in incandescent lamps, where an electric current passes through a tungsten filament inside a vacuum. As the filament heats up, it reaches a high temperature and begins to glow, emitting visible light. The color temperature of standard incandescent bulbs is around 2800K, giving off a warm, yellowish light that differs from natural daylight. One of the main advantages of incandescent lamps is their low cost and ease of installation. They are also suitable for frequent on-off cycles, as the switch-on process has minimal impact on their performance or lifespan. However, they do come with several drawbacks. Incandescent lamps have a relatively short lifespan and low energy efficiency. Only about 10% of the energy consumed is converted into visible light, while the rest is lost as heat through infrared radiation. Additionally, these bulbs emit a significant amount of ultraviolet (UV) light, which can cause fading or damage to sensitive materials such as fabrics, artwork, and photographs. This makes them less ideal for long-term use in environments where preserving colors is important. Despite their inefficiency, incandescent lamps are still widely used in certain applications due to their simplicity, affordability, and the soft, warm lighting they provide. However, many countries have started phasing them out in favor of more energy-efficient alternatives like LED or compact fluorescent lamps (CFLs).
