Lighting, as the important means of living environment, can distinctively affect humans living quality and environment itself. Lights, various shapes, colors, brightness, shapes, and applications make it possible to light up all kinds of spaces, whether commercial premises, public buildings, interiors, or outdoors. Lighting is the term that refers to the use of lights to illuminate an area, as well as lighting design as a tool to achieve desired effects. In addition to lighting spaces, lighting can also be used to create a certain atmosphere. A good lighting design can set the mood of a room, from romantic to dramatic, warm to cool, by the use of different light levels. For example, in a bedroom, selecting a warm, low wattage bulb can produce a charming, romantic ambience. Whereas a harder, brighter light can create a more modern and fashionable atmosphere in a living room. Lighting is an important part of any interior and exterior design. It can be used to accentuate architectural features, or highlight important elements within a space. It can also be used to create the illusion of space, and add character to a room. When it comes to outdoor lighting, safety is a key consideration. Lights used outdoors must be suitable for the weather, and be positioned to prevent trips and falls. In conclusion, Lighting is a powerful tool used to create the desired atmosphere, whether it is for a home, business or outdoor activities. With the right design, the right combination of lighting can create the perfect setting for any occasion.
