DALI is the young generation lighting control protocol in the realm of lighting control at present, which adopts Manchester encoding transmission, with overall grouping dimming, addressing dimming, various scene mode settings , brightness tracking , etc., powerful dimming functions . Modern top-grade hotels , shopping malls , and households increasingly request high standards for lighting systems . The DALI protocol bus-mastering, with simple, reliable, and superior functions , is widely used , demonstrating its powerful advantages in the realm of intelligent lighting control. DALI bus-mastering protocol is the intelligent lighting master used with dimmable ballasts to adjust the lighting scenarios of fluorescent lamps . The DALI LED dimmer launched by LTECH, which follows the IEC62386/IEC60929 standard, can connect any equipment that accords with the DALI protocol to one DALI bus-mastering, which realizes the integration of LED lighting products and traditional lighting in the same lighting system, greatly facilitating users.
