According to Various of bus protocol system，in addition to DMX512 and DALI deeply into the internal of lighting products。Other protocol just only to the wall of the connector and socket，not In deeply to internal of lighting products。In other words hadn’t unified standard according to the characteristics of various lighting and lighting terminal products, it is impossibility of open the function of lighting products。So，on one hand，they are only general simply on-off control and phase chopper。So ，has the very big limitation in the intelligent application of ordinary to office and family。and limited them to enter the general lighting market。On the other hand，because there hadn’t unified standard according to the characteristics of various lighting and lighting terminal products。And not have to in deeply to internal of lighting products。For various of lights products input supply to general simply adjustments to achieve the dimming purposes。Is easy to appear the lights flashing。Damaged the ballast controller or tubes，etc.， and even produce a security problems.Although the DMX512 into the internal of lights product。but the system is mainly for large stage lighting lamp design, many functions of the main consideration is the motor mechanical control, and no more consideration for the electric control by program cord。It’s not suitable for the ordinary office building lighting and household lighting in intelligent application。But some lights products with DALI digital addressable lighting interface。So as international unification standard into the intelligent ordinary office light and ordinary family light。The DALI digital addressable lighting interface is most promising， high quality and intelligent lighting control system。 The rapid development of DALI digital addressable lighting interface technology and DMX512 lighting technology application to update play a tremendous role in promoting。
