DALI is a technical standard promulgated by IEC, the standard number is IEC60929. DALI is English Digital Addressable Lighting
The abbreviation for Interface, which means "digital addressable lighting interface". (In short, it is a standard of digital communication protocol.

*What are the characteristics of dali switch power supply
DALI protocol control dimming is different from traditional lighting control! Simply put, no matter how many loops the system is designed, it can also achieve point-to-point dimming (ie one-to-one precise control) from the system loop. Traditional control can only control all modules in one loop; the characteristic of DALI application is that the bus system can Accurately identify the digital address of each DALI power module, and achieve precise one-to-one control. As long as the system supports, waterproof dali power supply can realize remote terminal control!

*How many lights can be connected to the DALI system? What is the distance of the bus
One bus can recognize 64 addresses (that is, it can control 64 lights), and it can be expanded indefinitely. Every time a control area is expanded, DALI control bus equipment must be added; the distance of the line is up to 500 yards; the bus has dali dimming led driver, which can guarantee maximum The agreement signal is stable!

*The original intelligent lighting control system is analog control, what is the difference between the DALI system and the traditional analog signal control system
First of all, each component in the DALI system has its own independent address, so it can realize direct communication with each component. In other words, on a pair of twisted-pair wires, the DALI system can control several sets of devices. Thirdly, the lights can be turned off by issuing instructions through the DALI system without having to set a switch on the main circuit. Fourth, the DALI system can not only issue instructions to the lighting device, but also receive signals fed back from the lighting device. The traditional control system can only send instructions to the lighting device from the system, and the gap between the two is obvious. The DALI system receives the feedback signal of the lighting device including: the status of the light, that is, is the light on or off? The preset lighting level and the state of the ballast. Fifth, the control line is simple. No matter what topology is adopted, the control line in the DALI system is an ordinary two-core cable. Sixth, the DALI system can be easily reconfigured. By resetting the program, the lighting scene and function can be easily changed without changing any hardware. Seventh, it is easy to add new components. When the lighting system needs to be expanded and new components are added, no matter where in the DALI system, just connect the component to the DALI network without rewiring.
