In recent years, with people's living standards improving, lighting quality requirements also increase correspondingly. Modern lighting systems require to achieve energy-saving, environmentally-friendly, and high efficiency and be comfortable, flexible, and human-oriented.

At this same time, with the development of information network technology, the KNX bus technology is becoming more and more mature, which has promoted the development of the intelligent building industry. Under the preconditions mentioned, the concept of an "intelligent lighting control system" emerged. The architecture of the system consists of a power supply that supplies the KNX bus. The KNX switch actuator is used to control the LED driver. With different input interfaces, you can control the light manually or adjust the light automatically. If a dimming function is required, an optional dimming switch actuator with a dimmable LED driver is expected.
