Light is a form of energy that travels in the form of a wave. It is visible only if it is contained in visible spectrum, which is just a tiny portion of the electromagnetic spectrum. We can see light because our eyes have special cells that respond to the different wavelengths of light. Light not only provides us with the ability to see our surroundings, but it also plays a major role in our well-being. In nature, sunlight is our primary source of light, which provides essential nutrients to our planet and its inhabitants. Lighting has also been used as a way of controlling our environment since ancient times. By manipulating the characteristics of light, such as intensity, color, and angle, we can influence our moods and behavior. Modern lighting can be found everywhere, from homes, businesses, and public venues, to areas where people work and gather. Through advancements in energy-efficient LED lighting, designers are now able to create stunning visual effects that provide a unique feeling of atmosphere. By controlling the direction, intensity, and spectrum of light, designers are able to create lighting that greatly enhances a space and increases its mood and functionality. The advancements in lighting technology have allowed us to use light in ways that were not possible before, giving us the ability to design and create spaces that are truly unique and artistic. Lighting has truly evolved into an art form, yet its primary purpose is still to provide us with safety, security, and proper illumination. Lighting also offers countless opportunities to be creative and express ourselves in ways that werent possible before.
