Lighting is generally defined as the deliberate use of light to achieve a practical or aesthetic effect. There are various kinds of lighting used in a variety of settings including indoor and outdoor lighting scenarios. With the help of lighting, the environment of space and architectural designs can be changed significantly. Good lighting is essential to the creation of any successful interior and exterior design project. It is usually the key element that will help to make a space feel comfortable, inviting and beautiful. Lighting can also be used to enhance the security of an area by reducing shadows that may be created by trees or buildings. When considering lighting design, the aim is to use light to create the desired atmosphere in a space. This is often achieved by the strategic placing of different types of lighting such as task lighting, accent lighting, and daylighting. Every architectural space contains different challenges, which should all be taken into account when designing the lighting plan. Task lighting is a type of lighting designed to provide an even illumination of an area, and usually used for work countertops or desks. Accent lighting focuses on a particular object or area, adding a dramatic effect. Daylight is indirectly used to flood a space with light from the outdoors. Today, there are many innovative lighting technologies available that allow for more freedom and creativity when it comes to designing lighting. LED lighting is one of the most popular types of lighting, as it is energy-efficient and has a very long life. Additionally, intelligent lighting systems are becoming increasingly common, enabling the user to control their lighting from their smartphone. All of these advancements have allowed designers to create new and interesting lighting solutions to suit almost every need. Lighting has the power to transform a space, and with so much creativity and energy now put into lighting design, it is no wonder that lighting has become one of the most impactful elements of any interior or exterior design.
