Lighting plays an important role in creating and defining space in architectural design. It has the capacity to control the ambient environment and to engage the viewer's emotions. By utilizing the right lighting fixtures, designers can create atmosphere, dimension, and focus interior elements. Lighting fixtures can provide both direct and indirect light, as well as integral accent illumination. Direct or artificial lighting is often used to highlight focal points and is usually desired for task-oriented purposes. Indirect lighting, on the other hand, creates the desired atmosphere that one may be seeking. At times, this can be achieved with a combination of both direct and indirect lighting. Accent lighting is usually used to bring attention to a surface or artwork. This type of lighting is often used in halls, foyers, stairwells, art galleries and patios. The best accent lights are often used for highlighting specific parts like artwork, furniture and architectural details. In addition to the practical uses of lighting, the use of light in architectural design can also be used to create an emotional effect. For example, light can be used to encourage people to explore a space or to draw attention to certain elements in a space. Different lighting techniques can be used to create different feelings, such as warmth, coziness, and energy. In conclusion, there are many different types of lighting fixtures available for architectural design. Lighting can be used to create atmosphere, dimension, focus and emotional effect. Different types of lighting can be used to create different types of experiences in any given space.
