Lighting as an environmental design element has a significant impact on our atmosphere, building construction, and daily behavior. Lighting can help create a space of comfort and security, highlighting important individuality in our daily lives. Lighting can be used to improve lighting and visibility, or reduce it for a restful environment. Most interior lighting installations use a combination of artificial, natural, and reflective light sources. This is usually because of the amount, type and quality of available light, and cost. Lighting is used to adjust ambience, create accent, and create an environment conducive to gathering. Color and brightness contrast between lighting and surfaces can create interest, excitement, or tranquility, depending on the sophistication of the fixtures used and the colors of the background surfaces. Lighting enhances aesthetic elements within a space, such as wall coverings or fabric textures. Lighting can also have an effect on building elements, by allowing or limiting activities to specific areas. Lights can also indicate directions, help with wayfinding, and provide informative guidance. Not only does lighting affect us functionally, but also emotionally. It evokes a variety of emotions and can be used to influence our moods. Emotional responses to lighting are determined by the quantity, quality, direction and color of light. When designing with lighting, careful thought should be taken to ensure the most effective use of a space. Good lighting design not only makes a space more aesthetically pleasing, but contributes psychologically to our well-being. With the right lighting, you can create an inviting and comfortable atmosphere.
