The original intelligent lighting control system is analog control. What is the difference between the DALI system and the traditional analog signal control system?

A: First of all, each component in the DALI system has its own address, so direct communication to each component can be achieved. The DALI system can control several groups of devices on a pair of twisted pairs. Third, the DALI system can issue a command to turn off the light without having to set a switch on the main circuit. Fourth, the DALI system can both issue commands to the lighting device and receive signals from the lighting device. The traditional control system can only send instructions from the system to the lighting device, and the difference between the two is obvious. The feedback signal of the DALI system receiving the lighting device includes: the state of the light, that is, whether the light is on or off? Preset lighting levels and ballast status. Fifth, the control line is simple. Regardless of the topology used, the control lines in the DALI system are ordinary two-core cables. Sixth, the DALI system can be easily reconfigured. By program resetting, it is easy to change the lighting scenes and functions without changing any hardware. Seventh, it is easy to add new components. When the lighting system needs to be expanded to add new components, no matter where in the DALI system, as long as the component is connected to the DALI network, no rewiring is required. (As long as the products are manufactured in strict accordance with the DALI protocol, there is no problem with the system being incompatible)
