DALI Lighting Control over other dimming options?
There are many ways to dim an LED lighting product but what have to be taken into consideration are the “Driver” and “Controller” The controller is down to choice and the responsibility of the designer and installer. The driver however is a matter of choice from the designer’s perspective in consultation with the client. The four classifications of controlling an LED light can be looked at as follows.
1) Non dimmable driver (Fixed constant current/voltage driver)
2) 1-10v analogue dimming driver
3) DSI (Digital Serial Interface) mostly only used by Tridonic drivers and is very much classed now as out of date
4) DALI (Digital Addressable Lighting Interface)
From the options above when it comes to dimming control in commercial buildings are, 1-10V, DSI and DALI. The first two are channel control protocols which control all the connected devices in the same way. The last, DALI can be used in the same way 1-10V and DSI systems. If you are deciding between these three options, using DALI instead of DSI or 1-10V can be implemented for almost the exact cost of the other two systems (DALI Drivers are in some markets equal to the DSI and 1-10V Drivers). More so, True DALI systems provide a future proof solution should the requirements for energy consumption change. (ie, due to the re-configurability of DALI)
Those two points aside, the following is a simple breakdown of the benefits of DALI to everyone involved, from the designer to the installer and users.
