Lighting is important to our daily life because it brightens our environment, providing us visibility and safety. It has a great impact on the interior design of a space and can be used to create different moods and atmospheres. There are many different lighting options available, such as incandescent lights, fluorescent lights and LEDs (light-emitting diodes). Incandescent lights use a filament of wire heated to produce light, and are still the most widely used lighting source. Fluorescent lights use a gas and electrical current to create an ultraviolet light, which in turn causes a phosphor coating on the inside of the bulb to emit a visible light. LEDs consume significantly less energy and generate much less heat than traditional bulbs, making them both energy efficient and cost-effective. Lighting can be used to highlight areas of a room, accentuate architectural features, or even provide background lighting. Task lighting is a practical type of lighting that provides illumination specifically for one activity, such as reading or cooking. Accent lighting can be used to draw attention to specific elements in a room, such as artwork or furniture. Lastly, ambient lighting is used to create a general level of illumination that covers a larger area. Modern lighting technology allows us to create a sophisticated lighting system that is not only pleasing to the eye, but more importantly energy efficient. With so many lighting options available, its easier than ever to find the perfect lighting for any given space.
