Lighting is the intentional use of light to achieve a practical or aesthetic effect. Lighting includes the use of both artificial light sources like lamps and natural illumination of interiors from daylight. Proper lighting can enhance task performance, improve the appearance of an area, or have positive psychological effects on occupants. Over lighting in an interior can lead to discomfort and glare. On the other hand, inadequate lighting can lead to eyestrain, headaches and a decrease in efficiency. Both natural and artificial lighting can be used in various configurations to enhance the look, feel, and atmosphere of a living space. There are several types of artificial lighting, the most common of which are incandescent light bulbs, fluorescent tubes, and LED bulbs. Proper lighting techniques can help conserve energy and result in fewer energy costs. So when choosing lighting fixtures, it is important to take into consideration both the energy efficiency and the aesthetic appeal of the fixtures. In addition to artificial light, natural light is also an important part of lighting. Natural light can be used to enhance living spaces, provide extra lighting in certain areas, or balance the color temperature of artificial lighting. Natural lighting can also be used to improve visibility and reduce glare in a space, which are both very important aspects of good lighting. Overall, lighting is an integral part of any living space, and can have a major impact on the dynamics of the space. So it is important to plan ahead and take into consideration all the different aspects of lighting. By creating a well-lit and inviting space, occupants can enjoy a comfortable and pleasant environment.
