Description

Technical Field

[0001] This utility model relates to the field of light guide tube system technology, and in particular to a roof ventilation light guide tube system. Background Technology

[0002] A light pipe system is a daylighting system that collects natural light and provides natural illumination to interior spaces and buildings by using highly reflective pipes.

[0003] Natural lighting has advantages over artificial lighting. Studies have shown that employees exposed to natural light in the workplace experience a significant reduction in eye strain, headaches, and fatigue, creating a healthier working environment.

[0004] Traditional light pipe systems utilize a light-collecting dome installed on the roof to guide light through a tubular system to each room requiring illumination. The light-collecting dome typically employs a dome structure to maximize the efficiency of sunlight collection throughout the day. The collected sunlight is guided through highly reflective pipes to minimize illumination loss. After the sunlight bends two or three times along its path, a diffuser is installed at the other end of the pipe to diffuse the light into the indoor areas.

[0005] Rooms that cannot obtain natural light through windows often face ventilation problems. For example, pump rooms or equipment rooms located underground, where workers need to operate equipment, typically have skylights installed in the roof to address both lighting and ventilation. However, skylights have limited lighting efficiency, and if ventilation is needed, the skylights must be opened from the roof, which increases the possibility of rainwater entering the room.
