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...

The evolution of street lighting systems is a reflection of the technological, social, and environmental advancements that have taken place over centuries. Street lighting has transformed from rudimentary and manual methods of lighting streets to sophisticated, energy-efficient, and smart systems that cater to modern urban needs. Below is an overview of the key stages in the evolution of street lighting: 1. Ancient and Pre-Industrial Street Lighting The earliest street lighting systems were primitive but served the essential function of illuminating public areas at night. Torches and Oil Lamps : In ancient civilizations, such as in Roman and Greek cities, simple torches or oil lamps were used to light the streets. These were usually mounted on poles or carried by individuals. Oil lamps, fueled by vegetable oils, animal fats, or later kerosene, were placed in street corners or public areas. Gas Lamps (Late 18th to Early 19th Century) : The use of gas lamps marked the first significant s...
