Lighting design is the creative process for developing lighting solutions for the safe, productive and enjoyable use of the built environment. In the past there has been an overwhelming emphasis on assuring that an appropriate quantity of light is delivered to the task or work surface. Quality of light has been considered mainly in the limited sense of controlling direct glare from luminaires or reflected glare from surfaces and objects. However, lighting design extends far beyond these factors. Light is one of the tools used to shape our environment, visually and emotionally. Lighting design is a synthesis of light and shadow, color, form, space, rhythm, texture and proportion, achieved through an understanding of the technology necessary to produce these effects. Working with these elements is what distinguishes the work of the lighting designer from that of the artist, from whom the lighting designer draws inspiration, and from that of the engineer, from whom the designer learns practical problem solving.
