Lighting is an essential element in home and office decoration. As one of the four basic elements of interior decoration, lighting is also one of the most important elements to consider when designing an environment. Good lighting can make a space look brighter, more spacious and create a more comfortable environment. Lights can also adjust the atmosphere, giving rise to different emotions according to their intensity, color, and direction. Besides its function of illuminating a room, lighting may also serve as a decorative purpose. Stylish and fashionable designs bring life and fun to any space. Special lights featuring geometric shapes, modern abstract designs, chandeliers, and hanging lamps are great for creating an atmosphere filled with atmosphere. The selection of lighting is vitally important when considering interior environment design. Various types of lights like wall lamps, down lights, spotlights, and hybrids are available to meet different needs in different rooms. As for energy-saving, LED lights and energy-saving bulbs are good choices. Lighting is a vital part of home and office furnishings. Without it, the atmosphere in a room would be dim and gloomy and it would be hard to create a comfortable environment. Therefore, when decorating a living space, considering the placement and selection of lighting is of utmost importance.
