With the continuous development of technology, lighting methods are also constantly innovating. Traditional skylights have defects such as local spotlighting, which is particularly prominent in large factories and other places. However, the sun tunnel lighting system can solve this problem and has many advantages. Firstly, the sun tunnel lighting system is not affected by changes in the angle of light incidence and provides a large and uniform lighting area, avoiding the occurrence of local spotlighting. In addition, compared to traditional skylights, the sun tunnel lighting system has higher installation flexibility and easier waterproof treatment. Different installation methods and waterproof measures can be used for different types of roofs, without being restricted by indoor ceiling structures, and are more convenient. The light pipe sun tunnel lighting system is composed of a light collector, light guide, and diffuser. The light collector, also known as the light hood, is the part of the system exposed to the outdoors, mainly collecting sunlight. Currently, light hoods are mainly made of PMMA or PC injection molding materials, with good light transmittance and impact resistance. The light guide is the key component for transmitting light and requires a surface material with high reflectivity to ensure system efficiency. The diffuser evenly distributes the collected outdoor natural light indoors while improving system efficiency.

The sun tunnel lighting system is suitable for various places. In terms of industrial buildings, such as large factories, warehouses, and subway maintenance facilities, the sun tunnel lighting system can greatly improve lighting effects and meet the requirements of working environments. In public buildings, such as shopping malls, supermarkets, stadiums, exhibition halls, and museums, the sun tunnel lighting system can provide sufficient natural light indoors and enhance the user experience. For military facilities, such as aircraft hangars, maintenance facilities, and equipment storage, the reliability and adaptability of the sun tunnel lighting system can meet the special requirements of military facilities. In addition, the sun tunnel lighting system is also suitable for civilian buildings, such as underground parking lots, airport terminals, schools, hospitals, government office buildings, hotels, and residential homes. Whether in public places or personal residences, the sun tunnel lighting system can bring natural and comfortable lighting indoors.

In summary, the lsun tunnel lighting system has many advantages, such as being unaffected by the angle of light incidence, providing a large lighting area, and distributing light evenly. In various applications, the sun tunnel lighting system can provide high-quality daylighting. In the future, with further technological advancements, the sun tunnel lighting system is expected to be applied in more fields and create a brighter environment for people.
