Light is a vital force in our lives, as it brightens our days and nights. Light is the main source of energy that drives and sustains life on our planet. It is also an essential element of the built environment as it creates atmosphere, delivers information, and performs a broad range of tasks that are used in everyday life. Light is primarily produced by the sun but it can also be created by artificial sources such as lamps or light emitting diodes (LEDs). To use lighting effectively, we need to understand its principles and how it works, as different types of light and lighting techniques are used to create a range of effects. Lighting can be used for many purposes. It can be used to illuminate a space, set the mood of a room, or even create a specific atmosphere. When using artificial lighting, one needs to consider the quality of the light, the intensity, and the direction of the light. Additionally, proper lighting control and maintenance can help reduce energy costs, provides color rendering, and improves the efficiency of lighting systems. Lighting continues to play a vital role in our modern lives, from providing general illumination to creating art. It can be used to create a variety of effects and can be used both indoors and outdoors. As technology improves, so too does our ability to manipulate light, creating ever more exciting and dramatic lighting designs.
