Lighting can be referred to as any form of illumination, whether natural or artificial, used to enhance visibility and provide safety and security for any event or activity. Lighting is used outdoors for venues like concerts, sports, and other entertainment, while indoor use includes domestic, commercial, and industrial use. Outdoor lighting has been used for centuries. Early Chinese and Egyptians used oil lamps and candles to illuminate their homes. During the 17th century, gas lanterns were popular for outdoor lighting. The invention of the modern light bulb by Thomas Edison in 1879 revolutionized outdoor lighting, providing brighter and more distributed light. Today, electricity provides the abundant and inexpensive energy needed for outdoor lighting. Lighting is also used for special occasions and in the dark. Ceremonies and other public events often use festive lighting to add color and style to the celebration. During night time, safety lighting is used to provide safety, security, and visibility. Flashlights, street lights, and other lighting fixtures are used for security purposes. These days, lighting has become much more specialized. LEDs, neon lights, and other technologies are used for a variety of purposes. LEDs are energy efficient and provide high brightness and a long lifespan. Theyre used for everything from decorative lighting to a flood light for sports fields. In conclusion, lighting is an essential part of everyday life. Lighting can enhance visibility, improve safety, and provide a festive atmosphere for special events and activities. New technologies such as LEDs have greatly expanded the possibilities of lighting.
