The dimming device for tubular daylighting system is driven by the small motor to open and close the shutter, which can adjust or even completely shut off the indoor illumination; this whole process takes no longer than only 10 seconds. There are two control modes: switch control and remote control.
A high precision illumination sensor is installed in the system, which can set the illuminance threshold of the sensor according to the indoor illumination requirement. When the indoor illumination is below the set value, the LED inside the system can be automatically connected to turn on the light. When the indoor lighting environment is relatively constant, the intelligent dimming device can also be connected to the automatic control, so that the indoor illumination is not affected by the outdoor light environment.

The integrated tubular daylight + ventilation system is an energy-free system in which a tubular daylighting system and a natural ventilation system are combined. Not only does it transmit natural light to the interior, but it also meets the needs for indoor natural ventilation. (Patent No.: ZL 2014 2 0745251.8)
