Light is a form of electromagnetic radiation visible to the human eye, essential for vision. It enables us to perceive objects and details in the environment. The lighting system refers to the infrastructure and devices designed to produce, distribute, and control light for various applications, including homes, streets, and industries. Efficient lighting systems balance energy use with optimal illumination, reducing energy waste and providing proper visibility. Friction to Heat The conversion of friction into heat is a physical process where mechanical energy, due to motion between two surfaces, transforms into thermal energy. When two surfaces rub against each other, the resistance generated creates friction, producing heat. This concept is utilized in traditional lighting systems, especially in primitive lamps where friction or fire was a source of illumination. Heat with Respect to Light Heat and light are interconnected in several lighting systems. For example, in incandescent...
