Abstract
LED lighting devices/systems having air quality detection functions and methods for detecting air quality using the LED lighting devices/systems are provided. Exemplary LED lighting device includes an air quality detection unit configured to detect air quality parameter; a controller unit connected to the air quality detection unit to process data corresponding to the air quality parameter; an LED light source assembly controlled by the controller unit and configured to provide lighting; and an LED driver and power supply unit connected to drive the LED light source assembly, and to supply power to the entire LED lighting device. Exemplary LED lighting system includes at least two nodes each including an LED lighting device. By combining an air quality detection unit with an LED lighting device that are widely distributed and installed, the disclosed LED lighting devices/systems thus provide real-time and convenient air quality monitoring.
