Lighting or illumination is the deliberate use of light to achieve a practical or aesthetic effect. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight. Daylighting is sometimes used as the main source of light during daytime in buildings. This can reduce energy costs and improve the aesthetics and usability of a space. Lighting can also be an intrinsic component of landscape projects. By adjusting the direction and intensity of light, the mood of a space can be significantly altered. Lighting technology has developed rapidly in recent decades, and there is a wide range of options to enhance the aesthetics and performance of lighting. Low energy sources like LED lights have grown in popularity for their energy efficiency and long lifespan. In contrast, the use of traditional incandescent lighting is being phased out due to its inefficiency. The use of lighting can significantly affect our safety. For example, improved lighting on roads can improve visibility and help reduce the risk of accidents. Similarly, improved lighting in public parks can discourage crime and provide a safer environment for users. In summary, lighting is an important part of our lives – from enhancing our safety and usability of spaces, to providing an aesthetic effect. As technology continues to advance, so too our ability to create unique and effective lighting solutions.
