Lighting plays an important role in people's daily life. It is used for building environmental illumination, making and creating atmosphere, highlighting aesthetic characteristics of architectural objects, expressing psychological meanings and enhancing safety. In order to meet the needs of people, different types of lighting have been researched and developed. Traditional lighting sources include incandescent lamps, fluorescent lamps, and high-pressure sodium lamps. These lighting sources were used for a long time until LEDs entered the market. LED lights offer a much more efficient option for lighting, consuming up to eighty percent less energy than traditional lighting sources. LED lighting technology not only provides a longer lifetime with lower maintenance cost, but also features low ultraviolet and infrared radiation levels. The development of LED lighting technology has also made possible creative designs for light fixtures. Compared to traditional lighting, LED lighting allows for more flexible designs, including ceiling lights, wall lights, and other decorative lighting fixtures. LED lighting is also increasingly popular in outdoor lighting, where it is being used in street and park lighting. In addition, LEDs are increasingly being used for automotive lighting. Overall, LED lighting has proved to be a great advances in lighting technology. It is energy efficient, flexible to design, and can be used in a variety of applications, from indoor to outdoor lighting. In the future, LED lighting technology will continue to evolve, further improving its quality and efficiency.
