Lighting is an essential part of our daily life—we can see it everywhere and it affects our mood, productivity and even our emotions. The way we use lighting can make a significant difference in the environment, whether we are in the office, home or outdoors. The earliest use of artificial lighting comes from Chinese philosopher and scientist Mozi, who is credited with creating the earliest oil lamps and candle sticks. Since then, lighting technology has evolved significantly. With the advancement in technology, our current lighting sources include florescent lamps, LEDS, and incandescent bulbs. Choosing the right lighting for a specific environment can be a difficult task. For the office, the use of brighter and more intense lighting can improve productivity and focus, while in the home, softer lighting can create a more relaxing atmosphere. Outdoors, light can be used to create an inviting atmosphere or to accentuate features of the architecture. Lighting is not only used to light up an environment, it can also be used as a tool to improve our mental and physical health. Studies have found that lighting can influence our sleep cycles and improve our mood. With the right lighting, we can have a better quality of sleep, increased alertness during the day, and improved mood and wellbeing. Overall, lighting is an important tool for daily life and should be carefully selected for each environment. With the right lighting, we can create environments that are more conducive to productivity, mood or sleep. Lighting can also be used to create a beautiful and inviting atmosphere.
