sijalicu

Sijalica is a term that primarily refers to an electric light bulb. This common household item, also known as a lamp, is a device that produces light from electricity. The most prevalent type of sijalica historically has been the incandescent bulb, which works by heating a filament until it glows. This filament is typically made of tungsten and is enclosed in a glass bulb filled with an inert gas or a vacuum to prevent oxidation.

While incandescent bulbs were once ubiquitous, they are now being phased out in many regions due to their energy inefficiency, as a significant portion of the energy they consume is released as heat rather than light. More energy-efficient alternatives like halogen lamps, compact fluorescent lamps (CFLs), and light-emitting diodes (LEDs) have become increasingly popular.

LED sijalice, in particular, have gained widespread adoption due to their exceptionally long lifespan and minimal energy consumption. They work by passing an electric current through a semiconductor material, causing it to emit light. This technology allows for a wide range of colors and brightness levels, making them versatile for various lighting applications. The term "sijalica" can also be used metaphorically to represent an idea or a moment of inspiration, akin to the English phrase "a light bulb moment."
