In its initials in English Digital Addressable Lighting Interface (DALI) is a protocol for DALI Lighting Control By ballasts can be controlled and dimmers and other devices. DALI was proposed as a successor to the lighting control system known as 1-10v (that is still in use) and his time as a competitor of a system called DSI.
One of the advantages of DALI is that it is an open standard and has no owner, ie anyone can develop their own teams DALI. Is it a replacement DALI DMX-512? No, there are some important differences that suggest that it is not a replacement.
If you want a quick response in an installation of lights (eg the case of the jacket with Capri ) DALI can not get the dynamics of DMX-512. In the case of a facility with 500 DMX-512 devices each device would receive updating their status every 23ms. In the case of DALI with a communication that operates at 1200 bps to update an installation of 63 devices arrive every 1s (16ms x device.) However, one of the advantages to be found in DALI is that their slow speed of communication is easily implemented with any small microprocessor.
If we refer to finished products, OSRAM development a number of very interesting products DALI, contralateral one allows up to 64 different RGB channels in a wide power range. All this via PC, remote controls, buttons, and dimmers.
In conclusion, if we talk about interactive installations, for DMX-512 now remains the most convenient. OSRAM DALI
