Level4 - Control Equipment Schematic

4.1 DALI Control Protocal Intergrated with BMS

DALI is stands for Digital Addressable Lighting Interface. It is a lighting interface system that allows lighting to use a digital signal for more precise and flexible control. Using a two-way method, the system enables the user to communicate with LED drivers and ballasts, and vice versa, via a DALI controller, which is typically a computer system with software or dimming controller. DALI is also an international standard ( IEC 62386), created to ensure compatibility and interchangeability across lighting systems in the industry. In this building and also the forth floor or FBS, DALI system are working together with Building Control System to correspond the environment and time, also to create scenes among all needed areas in the building.

4.2 DMX-DALI Conversion

With increasing crossover between the entertainment, architectural and commercial lighting sectors, environments that require integration between DMX and DALI equipment are becoming more common. To convert DMX into DALI in this building of facade lighting for the exterior wall washing light, DMX to DALI is required. DMX to DALI quad converts packets from a DMX controller to DALI commands, enabling control of up to four circuits of 64 DALI ballasts each. This will achieve that DALI discovery to identify devices on the network, and enables ballasts to be controlled with the usual Broadcast, Channel, Group and Scene commands.

4.3 PWM-DALI Conversion

In the FBS Hub, the RGB linear ceiling recessed light need convert from PWN to DALI system, which can extracts dimming levels and address information from the incoming DALI data to control each of these four PWM dimming outputs individually.
