Lighting is the process of setting up a light source in a certain area or room in order to produce a desirable effect. Lighting is a very important component of interior design, as it creates an atmosphere in a certain room or space, emphasizing on certain elements. When used correctly, lighting can have a positive impact on a persons well-being and improve their ability to concentrate. When considering lighting, there are many aspects to take into account. The size of the room, the type of furniture, its color scheme are all important factors to consider before choosing the type of lighting. There are different types of lighting to choose from, such as natural, ambient, task and accent lighting, each of these can be used in a different way to create a specific effect. Natural lighting is the most desirable for a living space as it is pleasant to look at and provides a sense of calmness. Natural light also helps to regulate body rhythms and can help to reduce energy bills. Ambient lighting is the light that fills a room and is used to brighten up a room, while task lighting is used for specific activities such as reading or cooking. Accent lighting is used to highlight artwork or a specific area of a room. Lighting should be chosen depending on the purpose of the room, for example, a living room should have bright, warm lights that are placed around the room to create a cozy atmosphere; while a bedroom will need softer, duller lights so that it can create a calming environment. Ultimately, the ideal lighting in a room will depend on the individuals preferences and the activity they will be using it for. It is important to ensure that all areas of the room are illuminated in order to create an atmosphere conducive to productivity, relaxation and overall wellbeing.
